The best way to understand the role of the topic sentence in paragraph development is to imagine that any given paragraph is a miniature essay that has its own thesis, support, and conclusion. The parts of a paragraph easily correspond to the parts of an essay:

Just as an effective essay starts off with an introduction that presents the paper's thesis statement and indicates the specific claim or argument that the essay will develop, each paragraph should begin with a topic sentence that indicates the focus of that paragraph, alerting the reader to the particular subtopic that the paragraph will provide evidence to support.

A strong topic sentence should be placed at or near the beginning of a paragraph. In addition, this sentence should focus on a specific issue, avoid the use of direct quotations, and leave room for support and analysis within the body of the paragraph. Read on to learn more about creating an effective topic sentence.

The topic sentence does not have to be the first sentence in the paragraph; however, it should come early in the paragraph in order to orient the reader to the paragraph's focus right away. Occasionally a writer may place a transition sentence before the topic sentence, to create continuity between topics.

Topic Sentence to begin paragraph:

In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness.

Transition Sentence + Topic Sentence to begin paragraph:

However, Morrison does not only use the emotional and spiritual bonds between her female characters to initiate their coming-of-age. In addition, the author uses the physical bonds of female friendship to propel her adolescent protagonists into self-awareness.

Specificity

Your topic sentence should be more narrowly focused than your thesis sentence, and you will want to make sure the claim you are making can be supported, argued, and analyzed within the body of your paragraph.

Example: In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness.

In this topic sentence, the essayist is arguing that physical bonds of friendship, specifically, make the female characters more self-aware. Because this idea can be refuted or supported by readers (based on how successfully the essayist persuades his or her readers with examples and analysis from the novel), and because the claim is narrow enough to address within a single paragraph, the above sentence is a successful topic sentence.

Direct Quotations (Are Best Avoided)

Although it might be tempting to begin a paragraph with a compelling quotation, as a general rule, topic sentences should state the main idea of the paragraph in your own words. Direct quotations have a place later in the paragraph, where they may be incorporated to support the topic sentence.

Needs Improvement: As Morrison (1982) conveyed, the girls' "friendship let them use each other to grow on…they found in each other's eyes the intimacy they were looking for" (p. 52).

Better: In the novel Sula , Morrison uses the physical bonds of female friendship to propel her characters into self-awareness. Pointing to the connection of eyes meeting and bodies growing together, Morrison makes coming-of-age an interactive physical process between the adolescent protagonists. Specifically, Morrison describes how Sula and Nel have used "each other to grow on…they found in each other's eyes the intimacy they were looking for" (p. 52).

In this second paragraph, the topic sentence appears first, immediately orienting readers to the main focus (or topic) of the paragraph. The quotation is used later in the paragraph as a form of evidence or support for the topic sentence.

If you are finding it challenging to create effective topic sentences, you might consider outlining before beginning to write a paper. The points and subpoints of an outline can then become the topic sentences for the paper's paragraphs.

Additionally, because the topic sentence functions similarly at the paragraph level to the thesis at the essay level, you may also find it helpful to check out our thesis statement construction information. Our resource on paragraphs has helpful information about the scope of a paragraph, as well.

Topic Sentence and Paragraph Organization

Paragraph organization refers to the way sentences are structured and ordered to create a unified and cohesive body of text.

The principal features to consider in paragraph organization are the topic sentence and controlling idea, supporting details, organizational patterns, and signal words. Together, these features develop a topic and connect ideas from one point to the next, logically and fluidly. This resource explains these features and provides numerous examples of paragraph organization.

The Topic Sentence and Controlling Idea

Similar to a thesis statement, which establishes the central focus or point of a whole piece of writing, a topic sentence works at the paragraph level to express the focus and general point of an individual paragraph. A topic sentence has two parts: 1) the topic that is being discussed throughout the paragraph and 2) a controlling idea that limits the focus on the topic to one point or idea. Each additional sentence in the paragraph then develops or expounds on that point with supporting details. The example topic sentence below is from a body paragraph in an informative essay.

Example Topic Sentence and Controlling Idea

The economy also plays a role in an increase in prescription pain reliever addiction.

The example topic sentence suggests the paragraph topic is “the economy,” and the controlling idea about the economy is how it “plays a role in an increase” in opioid addition. The signal word “also” connects this topic as an additional example or contributing factor to the opioid epidemic, the focus of the paper. The example below shows the topic sentence in the context of the complete paragraph.

The economy also plays a role in an increase in prescription pain reliever addiction. According to Jungeun Olivia Lee, a social work professor at University of Southern California, “The relationship between joblessness and substance abuse is strongest among people from low socioeconomic brackets, who might not be able to afford healthier ways to relieve their stress” (2017, as cited in Khazan, 2017, para. 8). Additionally, every point the unemployment rate rises, opioid-related death rates rise by almost 4 percent (Khazan, 2017). Unemployment makes it not only difficult for those suffering from pain to afford medication or healthy alternatives, but it can also contribute to depression and varying degrees of self-medication and addiction.

Supporting Details

In a paragraph, the topic and controlling idea are developed with supporting details. Listed here are some types of supporting details found in paragraphs along with an example of each in a sentence.

Facts: statistics or evidence from research that can be verified

• The office sold seven million dollars of real estate during the boom years.

Opinions: statements, quotes, or paraphrases from subject matter experts

• According to expert tea maker, Millie Stoff, there are three easy steps to making tea.

Definitions: explanations of what a term or concept means

• A crossover is a family vehicle with the features of a sedan, a mini-van, and an SUV.

Examples: parts, pieces, instances, traits, or specimens that illustrate the essence or character of a greater whole.

• Mario is a shy, introverted young man. For example, he has few friends and mostly keeps to himself.

Anecdotes: narrative accounts of one time or recurring events

• When I visited the Washington Monument, I enjoyed the 180-degree view the most.

Descriptions: a visual or sensory depiction of a person, place, event, activity, or idea

• Frostbit leaves crunched beneath our winter boots on the path through the snow-frosted trees.

Example Paragraph and Analysis of the Supporting Details

Hiking can be exhilarating during snowy winter months. When my friend and I visited North Carolina last January, we hiked in the Blue Ridge Mountains near the highest peak, Mount Mitchell, which is6,684 feet above sea level. We first crossed a foot bridge over a rapidly moving, ice-cold river and then followed a wooded trail up to a waterfall. Frostbit leaves crunched beneath our winter boots on the path through the snow-frosted trees. We saw deer and rabbits as we trekked up the path. I assure you that nothing feels better than inhaling crisp mountain air, but the neatest part of hiking in winter, besides the beauty of the mountain, is exhaling and seeing my breath turn to frost when it hits the cold air!

The topic sentence in the example paragraph indicates that the paragraph is on “hiking,” and the focus is that hiking is “exhilarating” during winter. The sentences in the paragraph support and develop this idea with an anecdote of the writer’s experience hiking up a mountain during winter. An anecdote is a narrative account that helps a reader understand an event or situation. Had the writer said hiking was “dangerous” instead of “exhilarating,” the anecdote in addition to the visual and sensory details, facts, and opinions about the experience would have been different. Additionally, while the sample paragraph is a personal account, writers in many professions use anecdotal evidence to report events from an objective point-of-view, where the writer is not a participant but rather a witness or observer.

Paragraph Organization

Along with having topic sentences and supporting details, paragraphs are also organized to achieve a certain purpose. However, just as a paragraph can contain different types of supporting details, a paragraph may also include more than one organizational pattern. Listed here are some common patterns for organizing a paragraph:

• Cause and Effect for showing how one thing leads to another
• Chronological Order for narrating events that occurred over time
• Classification for grouping things together according to their features
• Comparison and Contrast for showing how things are similar or different
• Definition and Example for defining a term or idea and then expanding it with examples
• Description for listing details
• Episode for presenting details or information about a specific event or anecdote
• General/Specific Order for presenting a general idea followed by specific examples
• Generalization/Principle for making a general statement or applying a broad principle to explain the supporting details
• Listing for presenting ideas from least to most important
• Order of Importance for building up to or leading away from the most important point.
• Problem and Solution for presenting an issue and a way to address it
• Process/Cause for explaining what or how something happens and then why
• Spatial Order for ordering details directionally

Signal Words

Signal words are signposts or clues to a paragraph’s organization. If the word “type” is used in a sentence, for example, it signals that the ideas involve types or classification, which is an organizational pattern. Signal words are context clues that hint at what the paragraph is about and how it is organized.

Listed here are signal words associated with different types of paragraph organization.

• Cause and Effect : because, consequently, for this reason, hence, and on account of
• Chronological Order : after, at last, at (time), as long as, at the same time, as soon as, before, during, eventually, finally, in (month or year), later, meanwhile, next, on (day or date), since, second, subsequently, then, until, and whenever
• Classification : categories, classes, classifications, elements, features, groups, kinds, methods, types, varieties, and ways
• Comparison and Contrast : another, both, however, likewise, one difference, on the other hand, on the contrary, similarity, similarly, unlike, and while
• Definition and Example : concept, defined as, described as, e.g., for example, for instance, i.e., illustrates, is, is called, is stated, known as, means, refers to, specifically, such as, term, and that is to say
• Description : above, across, along, appears to be, as in, behind, below, beside, between, down, in back of, in front of, looks like, near, onto, on top of, outside, over, such as, to the right/left, and under
• Episode : a few days/weeks later, around the same time, as a result of, as it is often called, because of, began when, consequently, for this reason, just, lasted for, led to, shortly thereafter, since then, subsequently, this led to, and when
• General/Specific Order : for example, for instance, indeed, in fact, in other words, like, namely, such as, and that is
• Generalization/Principle : additionally, always, because of, clearly, conclusively, first, for instance, for example, furthermore, generally, however, if…then, in fact, it could be argued that, moreover, most convincing, never, not only…but also, often, second, therefore, third, truly, and typically
• Listing : additionally, also, and, as well as, besides, furthermore, in addition, in fact, moreover, or, plus, and too
• Order of Importance : central, chief, ending with, finishing with, key, lastly, least, main, major, finally, primary, principal, and significant
• Problem and Solution : answer, challenge, difficulty, dilemma, enigma, indicate, improve, issue, need, plan, problem, propose, resolve, respond, solve, and suggest
• Process/Cause : accordingly, as a result of, because, begins with, consequently, effects of, finally, first, for this reason, how to, how, if…then, in order to, is caused by, leads/led to, may be due to, next, so that, steps involved, therefore, thus, and when…then
• Spatial Order : above, below, behind, beside, down, east, feels, highest, looks, lowest, next to, north, smells, sounds, south, tastes, under, and west

Sample Paragraphs and Analyses of the Organization

The sample paragraphs in this section illustrate topic sentences, supporting details, organizational patterns, and signal words in context. Read each paragraph to identify the type of paragraph organization on your own, and then proceed to the analysis to check your comprehension.

Sample Paragraph 1

• In 1995, Lawrence started his real estate business, and it has since become a huge success. When Lawrence Real Estate opened its door in Oviedo, Florida, it sold seven million dollars of real estate during the first few boom years. By 2000, Lawrence decided to open two branch offices: one in Tampa in 2003 and one in Miami in 2004. By 2007, the home office and both the branch offices had survived the economic slowdown, so Lawrence and his associates expanded their business to the Carolinas and opened a branch office in Charlotte in 2020. It can be safely said that Lawrence Real Estate has become a model for success despite economic struggles and real estate devaluation.

Analysis of Paragraph 1: According to the topic sentence, which contains two coordinating clauses and therefore two subjects and two topics, this paragraph is about Lawrence and his real estate business, and the controlling idea is that they have been successful.

To understand how the supporting details are organized to present information about this topic and idea, the reader can consider the supporting details. To do this, they look at the way the sentences begin and at any signal phrases that lead readers along a certain line of thinking. Here are some key signal words: “in 1995,” “By 2000,” “By 2007,” and “in 2020.” These dates make a pattern. They go back to 1995 and then in a chronological order, they move forward to when the success of the business happened.

This paragraph uses chronological order . The reader will notice too that the last sentence returns to the beginning idea of 15 years ago. In this sentence, a final comment about the time period overall is given with respect to the new information

Sample Paragraph 2

• Making a great cup of tea is easy if you follow these three steps. First, heat a cup of water to the boiling point. Then put the tea bag in the hot water, and let it steep for at least three minutes. Finally, add creamer and sugar to taste. There is nothing tastier than a strong cup of tea early in the morning.

According to the topic sentence, which is the first sentence of the paragraph, making a cup of tea is the topic, and the controlling idea is that it’s easy to do if you follow three steps. Signal words open the following sentences: “first,” “then,” and “finally.” These indicate a sequence of steps, not times or dates as in a narrative story, but steps that happen in a specific order as in the process of doing something or informing others how to do something.

This paragraph uses process order (or process/cause). In the last sentence of this paragraph, the process is completed with a return to the original topic—a cup of tea—and a new comment about it—that a strong cup is tasty in the morning, making those three steps not only easy but also worthwhile.

Sample Paragraph 3

• The Washington Monument is divided into three main areas. The lowest section of the building houses the entrance, a gift shop, and a restaurant. The middle section consists of elevators and stairways to the top. The top section of the monument includes an observation deck with a spectacular view of the Washington D.C. area. When I visited the Washington Monument, I toured every section but enjoyed the spectacular 180-degree view the most.

Based on the topic sentence at the beginning of the paragraph, the topic is the Washington Monument, and the controlling idea is that it is divided into three main areas. The paragraph presents information about the lowest section first, the middle section second, and the top section third. The last sentence makes a remark about the most enjoyable of all the sections. This is an example of spatial organization . The information is given in the order you might see it if you were there.

Sample Paragraph 4

• There are three types of family vehicles made in the United States. The first type is the minivan. All American car manufacturers make a version of the minivan. Some say that the comfort and amenities of the minivan compare to none. The second type of family vehicle is the SUV. Some SUVs offer four-wheel-drive to navigate tough terrains, and they also offer seating for a large crowd. A third type of family vehicles is called the crossover. These vehicles supposedly have the best features of the sedan, minivan, and SUV. They are easy to maneuver, look much like a regular sedan, and sit up to six people. All of these vehicles are family friendly; they offer safety, roomy comfort, and many extra features to accommodate the special needs of families.

This paragraph shows another way to organize the details of a topic. The topic sentence of this paragraph is structured differently than the previous ones. Typically, the topic of a sentence is also the grammatical subject, but the subject in this sentence is “there,” a pronoun, and the topic that tells what the paragraph is about, “family vehicles,” is in the predicate of the sentence. The controlling idea is that there are three types made in the U.S.

The paragraph is organized according to those three types: the first type, the second type, and the third type. To conclude, there is a comment about “all of these vehicles” or all of these types of vehicles. When information is organized by types or features, the information is classified. This type of organization is classification .

Sample Paragraph 5

• Although the twin brothers share many physical characteristics, they handle themselves differently in social situations. Mario is a shy introverted young man. He has few friends and mostly keeps to himself. On the other hand, Gino is outgoing and the life of the party. Unlike Mario, Gino has many friends and feels totally at ease among big crowds. The best way to tell these identical twins apart is to invite both to a party and observe how differently they interact with the other guests.

When the topic sentence is complex (having more than one clause) as in this paragraph, there may be two subjects and therefore two topics; however, here, the subject of the first clause is “the twin brothers” and the subject for the second clause is “they,” so both subjects refer to the same topic—the twin brothers. The controlling idea is that the twin brothers share many physical characteristics but handle themselves differently socially.

The paragraph then progresses with descriptions of these similarities and differences. Contrast is created by signal phrases and words such as “although, “on the other hand,” and “unlike.” Words such as “apart” and “differently” also indicate that the organizational pattern of this paragraph is comparison and contrast .

Sample Paragraph 6

• There are many reasons why I enjoy walking tours when visiting new cities. For starters, walking through a city allows the visitor to see the details of an area without having to hurry. This often results in meeting locals and experiencing their lives and traditions first hand. Furthermore, walking tours are flexible and inexpensive because there are no strict schedules or transportation expenses. Travelers taking walking tours are rewarded with firsthand experiences in the places they visit and the opportunity to personally interact with the people who live there.

Because the first sentence begins with “there are,” the reader must move beyond the subject and verb to find the topic. Additionally, this is a complex sentence with an independent and dependent clause connected by “why,” so there may be two topics. Looking at the objects of both clauses, the reader finds “many reasons” and “walking tours.” These two topics are linked together by the controlling idea: the writer enjoys walking tours while visiting new cities for many different reasons.

The signal words build on this idea of “why” with terms such as “results” and “because.” The last sentence then sums up the ultimate effect of walking tours: Travelers are rewarded. This is an example of cause and effect organization.

Sample Paragraph 7

• Hiking can be especially exhilarating during snowy winter months. When my friend and I visited North Carolina last January, we hiked in the Blue Ridge Mountains near the highest peak, Mount Mitchell, which is 6,684 feet above sea level. We first crossed a footbridge over a rapidly moving, ice-cold river and then followed a wooded trail up to a waterfall. Frostbit leaves crunched beneath our winter boots on the path through the snow-frosted trees. We saw deer and rabbits as we trekked up the path. I assure you that nothing feels better than inhaling crisp mountain air, but the neatest part of hiking in winter, besides the beauty of the mountain, is exhaling and seeing my breath turn to frost when it hits the cold air!

In the first sentence, the topic of the paragraph is “hiking,” and the comment or main idea is that it “can be especially exhilarating during snowy winter months.” Based on this, the reader can expect supporting details to illustrate this exhilaration, but they do not know how it is organized until they look at the signal words that help progress the topic from one idea to the next.

Taking inventory of the signal words, the reader will find several time markers: “When” and “last January” set the narrative in the past while “first” and “then” develop a chronological order of events. The final summarizing sentence about hiking “in winter” reminds the reader of the season.

Within this chronology , signal words are associated with spatial organization: “over,” “up,” “beneath,” “through,” “crunched” (sounded), “saw,” “feels,” and “seeing.” Narratives typically include descriptive elements about the setting. Additionally, the concluding thought contrasts “inhaling” to “exhaling.” The reader can thus conclude that this paragraph has multiple patterns of organization that are intricately connected.

The structure of academic writing requires several standards to be followed to ensure the coherence of your essay. One of the techniques you should use in your writing is essay topic sentences. However, why is it necessary, and how to write a topic sentence? We will answer this and many further questions in this article. Keep reading if you want to know:

• The essence of the topic sentence and its use;
• The crucial aspects of composing a topic sentence;
• Types of topic sentences and their implementation in the text;
• How to write your topic sentence and see the examples of it.

A strong topic sentence is a guarantee to be heard by the readers! Let’s start by looking at the meaning of this term and the main purpose of topic sentence.

What Is a Topic Sentence

A topic sentence is a generalized main idea of a paragraph summarized in one phrase. This statement provides a smooth transition from one central point to the next. But do not confuse it with the thesis statement. So, let’s review the topic sentence vs thesis statement and see if there is any difference.

A thesis statement sums up the idea of your essay or thesis, but it is usually found in the introduction, presenting the main point of the whole piece. Our service is ready to help you with writing a thesis statement correctly to ensure the highest results. An effective topic sentence includes two parts: the topic and the controlling idea. Use a topic sentence to organize your formal writing. Thus, you will delimit the main ideas within the boundaries of your essay paragraphs and ensure your text is coherent. This technique also aims to interest the reader by revealing the concept of your written work.

Characteristics of an Effective Topic Sentence

Using a topic sentence is an efficient strategy that will inform a reader about the topic of its paragraph briefly. To achieve this result of idea explanation and its evolution through the following parts of the text, learn the main characteristics of effective topic sentences. Below, we listed particular features that create a perfect topic sentence formula.

A good topic sentence requires clarity and unambiguity. The reader must understand exactly what work he is about to read. Therefore, your task is to introduce the main idea of each paragraph clearly.

Always remember about the idea of your paper, and don’t add anything extraordinary. You should only include information in your topic sentences that will be presented in the supporting sentences of the body part of an essay . Thus, your text will be easy and exciting to read, regardless of the topic.

• Completeness

You are faced with the difficult task of condensing a complete main idea into just one topic sentence. It must be comprehensive, express a complete thought, contain the controlling idea, and convey the topic you presented in a particular paragraph.

The topic sentences should motivate further reading. Therefore, you should present the information in a captivating way, ensuring the reader’s interest.

Types of Topic Sentences

There are three main types of topic sentences that cover a wide range of functions. Each type is suitable for a different purpose, but they all aim to include the key information in the current paragraph and emphasize the reader’s attention to it.

Interrogative

The topic sentence is presented as a question, and the following paragraph provides the answer. Such a topic sentence will effectively attract attention, increasing interest in reading. However, be careful to give an unambiguous answer to the question posed in your topic sentence.

Topic: Fast fashion

Topic sentence: What changes are required in the organization of the fashion industry to overcome total environmental pollution?

Reinforcement

Topic sentences and supporting details can serve as a reinforcement, supporting the central idea expressed in the essay’s thesis statement. This keeps the story flowing, showing that you’re not jumping between ideas inconstantly.

Thesis statement: AI development will provide the labor market with dozens of new positions.

Topic sentence: A lot of new job opportunities will be discovered with the development of AI.

Transitional

The topic sentences can also play the role of a link, logically and smoothly connecting several paragraphs into one whole. In this way, a clear structure of academic writing is maintained, and the author can relate one central point to another.

Last sentence of the previous paragraph: The issue of the need for school uniforms has been actively discussed for many years.

Topic sentence: School uniform is necessary for the development of discipline in children.

How to Write a Good Topic Sentence

First, remember that the focus sentence is the most important sentence in a paragraph. It should not only state the paragraph’s main idea, but it should be intriguingly interesting, concise, and include a controlling idea. Experts of our writing service have prepared for you some tips on how to make a topic sentence. It’s important to consider many different factors before writing a topic sentence for an essay. Keep reading to see the most essential ones.

Understanding the Paragraph’s Main Idea

The key to writing the topic sentence is to determine the main point of the paragraph. Think about the purpose for which you wrote this fragment. What would you like the reader to remember most? In other words, if you extract all the topic sentences from your essay and compose a text from them, you will get a complete digest of all the main ideas of the thesis.

Keeping it Concise

Sometimes, it can be difficult to fit everything you want to convey to the reader into one concluding sentence. After all, everything you wrote is valuable information worthy of attention. Still, be brief when writing your topic sentence to entice the audience to continue reading the rest of the paragraph.

Positioning the Topic Sentence

The topic sentence can be written in any part of the paragraph. Most commonly, placing it in the beginning, thus you ensure a smooth transition from the previous paragraph and give readers a hint about what the upcoming piece will be about. If it’s in the middle of the text, it can describe the main idea after having revealed some crucial background details of the main idea. When you write the topic sentence at the end of the paragraph, it concludes and highlights the essential concepts of the piece.

Make it Interesting but not Over-complicating

To start with, brainstorm to point out the most creative and interesting idea for your topic sentences. For example, if you use statistics in later paragraphs, include them in the hook sentence as well, this will intrigue readers. At the same time, do not forget that due to the topic sentence structure, the size of the topic sentence is very limited, so do not try to overcomplicate it.

Better to Use Active Voice

From a grammatical and lexical point of view, it is believed that the passive voice complicates the construction of sentences. You may consider the previous sentence as an example of a topic sentence that is difficult for a reader. Your topic sentences should be brief and comprehensive yet simple to understand. Prefer active voice to make the body paragraph easier to read.

Enhance with Evidence

First of all, any essay, likewise scientific work, requires accuracy. That is why using verified statistical data and citing reliable sources makes your topic sentence and controlling idea credible and respected. Pay attention to the plausibility of data when you write academic essay papers to avoid misleading information. Topic sentences for essays should also contain precise facts, which you subsequently describe in the new paragraph.

Bind the Paragraph Together by Repeating Words or Phrases

In poetry, there is a technique called anaphora, when each line or sentence of a verse begins the same. This is often used to influence the reader’s emotions, strengthening his awareness of a certain concept of the subject. So, to reinforce your main idea and relate your paragraphs, you can also use this device in your essay writing.

Use Transition Words

Of course, without connecting words, argumentative essays will turn into a collection of words and incoherent sentences. Build a clear essay structure by combining topic sentences with the rest of the paragraph with linking words. Therefore, to make your narrative coherent and logical, you should soften the transitions. Introduce these words at the beginning: first of all, to start with, therefore, based on this, moreover, and many others to enrich your writing.

Examples of Topic Sentences

Modern technologies have helped to significantly simplify working conditions for people. For centuries, people have had to work hard to provide basic means of living. In the absence of mechanization, unfathomable amounts of effort were required to complete basic tasks. For this reason, people worked day and night for six days a week and, in some cases, without days off at all. However, our generation was much luckier. The development of artificial intelligence and the automation of most production processes at this point allow people to work more efficiently while spending less time and effort.

What we know about recycling is a drop, what we don’t know is the ocean. In recent years, there have been many environmental campaigns to explain the importance of recycling. Most developed countries invest a large share of their budget in developing environmental solutions for the most optimal recycling of waste. However, at the same time, ordinary users still know very little about the rules for sorting waste. In reality, only a very small percentage of plastic can be recycled. Few people know that only the cap of a plastic bottle is recycled.

Society is moving online, and the changes it brings to the future are difficult to ignore. Of course, we don’t know exactly what the future of our society will be, but now we can trace some trends that will lead to steady changes. The children from the youngest age know how to use gadgets and independently find information on the Internet. Friendship, relationships, study, work, and all this already exist in the electronic dimension. Sociologists are interested in the question of what the society of the future will look like and whether there will be a place for offline communication in it.

The eternal question of style: to follow or not to follow the fashion trends. There probably is no single correct answer to this question. Social media influencers are actively sharing the hottest trends in the fashion world. The main fashionistas immediately run to the store to buy the latest new items. However, one thing is obvious – trends are certainly not for everyone. Starting from different body types to color types. We are all different, and this is our uniqueness. Trends certainly cannot look complimentary to everyone.

Our inner confidence provides external attractiveness. I have seen more than once that confident people often receive more positive attention. This is due to certain biological factors since a person with leadership qualities can lead a community, and therefore, people are drawn to him/her. And yet the advantage is not only respect from others. People with high self-esteem are perceived as more physically attractive.

Topic Sentences as an Integral Part of Every Paragraph

Your creative ideas that bring scientific novelty are the key element of your academic essays. At the same time, an idea without form is just a set of concepts. Using topic sentences will help you navigate and organize your ideas in a logical flow. Furthermore, it not only provides direction and focus for a paragraph, ensuring coherence and unity, but it also guides the reader’s journey through a text.

TOPIC SENTENCE/ In his numerous writings, Marx critiques capitalism by identifying its flaws. ANALYSIS OF EVIDENCE/ By critiquing the political economy and capitalism, Marx implores his reader to think critically about their position in society and restores awareness in the proletariat class. EVIDENCE/ To Marx, capitalism is a system characterized by the “exploitation of the many by the few,” in which workers accept the exploitation of their labor and receive only harm of “alienation,” rather than true benefits ( MER 487). He writes that “labour produces for the rich wonderful things – but for the worker it produces privation. It produces palaces—but for the worker, hovels. It produces beauty—but for the worker, deformity” (MER 73). Marx argues capitalism is a system in which the laborer is repeatedly harmed and estranged from himself, his labor, and other people, while the owner of his labor – the capitalist – receives the benefits ( MER 74). And while industry progresses, the worker “sinks deeper and deeper below the conditions of existence of his own class” ( MER 483).  ANALYSIS OF EVIDENCE/ But while Marx critiques the political economy, he does not explicitly say “capitalism is wrong.” Rather, his close examination of the system makes its flaws obvious. Only once the working class realizes the flaws of the system, Marx believes, will they - must they - rise up against their bourgeois masters and achieve the necessary and inevitable communist revolution.

Not every paragraph will be structured exactly like this one, of course. But as you draft your own paragraphs, look for all three of these elements: topic sentence, evidence, and analysis.

Paragraphs & topic sentences.

A paragraph is a series of sentences that are organized and coherent, and are all related to a single topic. Almost every piece of writing you do that is longer than a few sentences should be organized into paragraphs. This is because paragraphs show a reader where the subdivisions of an essay begin and end, and thus help the reader see the organization of the essay and grasp its main points.

Paragraphs can contain many different kinds of information. A paragraph could contain a series of brief examples or a single long illustration of a general point. It might describe a place, character, or process; narrate a series of events; compare or contrast two or more things; classify items into categories; or describe causes and effects. Regardless of the kind of information they contain, all paragraphs share certain characteristics. One of the most important of these is a topic sentence.

TOPIC SENTENCES

A well-organized paragraph supports or develops a single controlling idea, which is expressed in a sentence called the topic sentence. A topic sentence has several important functions: it substantiates or supports an essay’s thesis statement; it unifies the content of a paragraph and directs the order of the sentences; and it advises the reader of the subject to be discussed and how the paragraph will discuss it. Readers generally look to the first few sentences in a paragraph to determine the subject and perspective of the paragraph. That’s why it’s often best to put the topic sentence at the very beginning of the paragraph. In some cases, however, it’s more effective to place another sentence before the topic sentence—for example, a sentence linking the current paragraph to the previous one, or one providing background information.

Although most paragraphs should have a topic sentence, there are a few situations when a paragraph might not need a topic sentence. For example, you might be able to omit a topic sentence in a paragraph that narrates a series of events, if a paragraph continues developing an idea that you introduced (with a topic sentence) in the previous paragraph, or if all the sentences and details in a paragraph clearly refer—perhaps indirectly—to a main point. The vast majority of your paragraphs, however, should have a topic sentence.

PARAGRAPH STRUCTURE

Most paragraphs in an essay have a three-part structure—introduction, body, and conclusion. You can see this structure in paragraphs whether they are narrating, describing, comparing, contrasting, or analyzing information. Each part of the paragraph plays an important role in communicating your meaning to your reader.

Introduction : the first section of a paragraph; should include the topic sentence and any other sentences at the beginning of the paragraph that give background information or provide a transition.

Body : follows the introduction; discusses the controlling idea, using facts, arguments, analysis, examples, and other information.

Conclusion : the final section; summarizes the connections between the information discussed in the body of the paragraph and the paragraph’s controlling idea.

The following paragraph illustrates this pattern of organization. In this paragraph the topic sentence and concluding sentence (CAPITALIZED) both help the reader keep the paragraph’s main point in mind.

SCIENTISTS HAVE LEARNED TO SUPPLEMENT THE SENSE OF SIGHT IN NUMEROUS WAYS. In front of the tiny pupil of the eye they put , on Mount Palomar, a great monocle 200 inches in diameter, and with it see 2000 times farther into the depths of space. Or they look through a small pair of lenses arranged as a microscope into a drop of water or blood, and magnify by as much as 2000 diameters the living creatures there, many of which are among man’s most dangerous enemies. Or , if we want to see distant happenings on earth, they use some of the previously wasted electromagnetic waves to carry television images which they re-create as light by whipping tiny crystals on a screen with electrons in a vacuum. Or they can bring happenings of long ago and far away as colored motion pictures, by arranging silver atoms and color-absorbing molecules to force light waves into the patterns of original reality. Or if we want to see into the center of a steel casting or the chest of an injured child, they send the information on a beam of penetrating short-wave X rays, and then convert it back into images we can see on a screen or photograph. THUS ALMOST EVERY TYPE OF ELECTROMAGNETIC RADIATION YET DISCOVERED HAS BEEN USED TO EXTEND OUR SENSE OF SIGHT IN SOME WAY. George Harrison, “Faith and the Scientist”

In a coherent paragraph, each sentence relates clearly to the topic sentence or controlling idea, but there is more to coherence than this. If a paragraph is coherent, each sentence flows smoothly into the next without obvious shifts or jumps. A coherent paragraph also highlights the ties between old information and new information to make the structure of ideas or arguments clear to the reader.

Along with the smooth flow of sentences, a paragraph’s coherence may also be related to its length. If you have written a very long paragraph, one that fills a double-spaced typed page, for example, you should check it carefully to see if it should start a new paragraph where the original paragraph wanders from its controlling idea. On the other hand, if a paragraph is very short (only one or two sentences, perhaps), you may need to develop its controlling idea more thoroughly, or combine it with another paragraph.

A number of other techniques that you can use to establish coherence in paragraphs are described below.

Repeat key words or phrases. Particularly in paragraphs in which you define or identify an important idea or theory, be consistent in how you refer to it. This consistency and repetition will bind the paragraph together and help your reader understand your definition or description.

Create parallel structures. Parallel structures are created by constructing two or more phrases or sentences that have the same grammatical structure and use the same parts of speech. By creating parallel structures you make your sentences clearer and easier to read. In addition, repeating a pattern in a series of consecutive sentences helps your reader see the connections between ideas. In the paragraph above about scientists and the sense of sight, several sentences in the body of the paragraph have been constructed in a parallel way. The parallel structures (which have been emphasized ) help the reader see that the paragraph is organized as a set of examples of a general statement.

Be consistent in point of view, verb tense, and number. Consistency in point of view, verb tense, and number is a subtle but important aspect of coherence. If you shift from the more personal "you" to the impersonal “one,” from past to present tense, or from “a man” to “they,” for example, you make your paragraph less coherent. Such inconsistencies can also confuse your reader and make your argument more difficult to follow.

Use transition words or phrases between sentences and between paragraphs. Transitional expressions emphasize the relationships between ideas, so they help readers follow your train of thought or see connections that they might otherwise miss or misunderstand. The following paragraph shows how carefully chosen transitions (CAPITALIZED) lead the reader smoothly from the introduction to the conclusion of the paragraph.

I don’t wish to deny that the flattened, minuscule head of the large-bodied "stegosaurus" houses little brain from our subjective, top-heavy perspective, BUT I do wish to assert that we should not expect more of the beast. FIRST OF ALL, large animals have relatively smaller brains than related, small animals. The correlation of brain size with body size among kindred animals (all reptiles, all mammals, FOR EXAMPLE) is remarkably regular. AS we move from small to large animals, from mice to elephants or small lizards to Komodo dragons, brain size increases, BUT not so fast as body size. IN OTHER WORDS, bodies grow faster than brains, AND large animals have low ratios of brain weight to body weight. IN FACT, brains grow only about two-thirds as fast as bodies. SINCE we have no reason to believe that large animals are consistently stupider than their smaller relatives, we must conclude that large animals require relatively less brain to do as well as smaller animals. IF we do not recognize this relationship, we are likely to underestimate the mental power of very large animals, dinosaurs in particular. Stephen Jay Gould, “Were Dinosaurs Dumb?”
