4. WRITING TOPIC SENTENCES FOR PARAGRAPHS
A paragraph is a sequence of sentences which cooperate in supporting one main point. Sometimes that point is so obvious that it doesn't need to be stated, but often a paragraph begins with a topic sentence which states the main point directly. Before you can decide on a topic sentence, you must decide what you want to say and what you don't want to say. In other words, you must first explore your starting topic and then select your limited topic. The next step is to make a statement about the limited topic. Keep these points in mind: 1) A starting topic is usually broad, stimulating many ideas. 2) A limited topic is narrow, connecting a few selected ideas. 3) A topic sentence makes a statement about the limited topic. For example, study this progression:
- Starting topic: Football
- Limited topic: The role that football has played in my education
- Topic sentence: If it hadn't been for football, I might never have taken school seriously.
EXERCISE A: Study a limited topic you have chosen as a result of freewriting or clustering. What statement can you make about that topic? Write a topic sentence that could introduce a paragraph on that limited topic. Check to make sure that it is a complete sentence.
A topic sentence is always a complete sentence expressing an idea about the limited topic. It is not a title (What football means to me), or an explanation of the writer's plan (I am going to tell you about the role football played in my education.) The more clearly it focuses the reader's attention on the points covered by the paragraph, the better.
EXERCISE B: For each limited topic below, circle the numbers of two items which could serve as topic sentences.
Limited topic: how to train a cat.
- This paragraph is about how to train a cat.
- Before a cat learns anything, it first teaches its owner a lesson in humility.
- Everything you wouldn't have thought to ask about training a cat.
- Training a cat takes physical stamina.
- Animal training is a complicated subject.
Limited topic: changes in patients' attitudes as they settle into convalescent homes
- Americans are learning how to grow old gracefully.
- The outside world seems to shrink when seen through the window of a convalescent home.
- Closing up a home and moving to a small room can make even an extrovert turn inward.
- It is important to look at the changes in patients' attitudes as they settle into convalescent homes.
- The increasing delight in daily conversation as patients become accustomed to life in a convalescent home.
Notice that choosing a topic sentence helps to focus the topic still further. The student writing about the role football played in his education could have chosen one of these topic sentences instead:
- My high school football coach transformed a sport into a powerful mental discipline.
- The lessons I learned from playing high school football prepared me for the challenges of college.
Each sentence declares a slightly different role that football played in this student's education and alerts the reader to a different focus in the paragraph. Therefore, the topic sentence acts as a tool for organizing the rest of the paragraph.
EXERCISE C. Click HERE to see a table showing the Nielsen Ratings for the week of January 22, 1996. (This is a large document -- 205k -- and may take a moment to download.) Nielsen ratings purport to show the relative popularity of television programs; they measure the millions of households tuned in to various programs and rank those shows accordingly. The figures on the chart are explained at the bottom of the chart.
Below are three topic sentences. Use the topic sentences to help you select and organize the facts in these Nielsen ratings. Under each topic sentence, list three details a writer could include in a paragraph introduced by that sentence.
1. Topic sentence: Sports programming has proven to be a big winner for television networks.
Supporting details:
2) Topic sentence: Commercial sponsors were wise to invest in NBC during this week in 1996.
Supporting details:
3) Topic sentence: Situation comedies ("sitcoms") such as Friends and Seinfeld seem to do best when grouped with other sitcoms.
Supporting details:
Compare your selection of facts with those of a classmate to see that you have considered all the possibilities. Be sure that neither of you has included facts that will not support the topic sentence.
5. GIVING EXAMPLES AND EXPLANATIONS
Giving examples and explanations helps your reader understand what has led you to a conclusion. Whenever you're writing, imagine a reader asking constantly, "What makes you say that?" "What do you mean?" If you heard that question in conversation, you'd probably answer, "Well, for instance. . . " and then you would give an example. You need to give examples in writing, too. Here are some statements that could lead readers to ask those questions:
- Fruit is good for you.
- People who live together fight sometimes.
- Reading enriches your life.
An example may offer further information, apply a general statement to a specific problem, or tell a story. Its purpose is to tie your idea to other ideas that everyone recognizes, proving that you know what you're talking about and encouraging your readers to stay on the path of your thought.
EXERCISE A: Support each statement below with examples and explanations, adding one more item to each column.
Statement: Fruit is good for you
