If it is neither first nor last the topic sentence will, of course, appear somewhere in the middle of the paragraph. In this case, the topic sentence splits the paragraph into two parts: those sentences preceding it and those that follow it. The sentences that precede the topic sentence often lead up to or introduce the main idea. At other times, the preceding sentences often lead up or introduce the main idea. At other times, the preceding sentences may function as a transition, connecting the ideas to be expressed in the paragraph with ideas in previous paragraphs. The sentences that follow the topic sentence usually explain, describe, or provide further information about the main idea. Notice the placement of the topic sentence as you read the following paragraph. [5] There are 74.5 million television sets in the United States, at least one set for 98 percent of all American homes. Forty-eight percent of all U.S. homes have more than one set, and some families even have a set for every person in the house. Yet, despite the fact that the number of sets in the United States has virtually reached a saturation point, the amount of time spent watching television has declined steadily since 1973. Explanations vary from the increasingly poor quality of network shows the rising popularity of home video equipment, but the fact remains that we are owning more sets but enjoying them less. The main idea of this paragraph is despite the fact that the number of sets in the United States has virtually reached a saturation point, the amount of time spent watching television has declined steadily since 1973.2.2.2 Implied main ideas
Although most paragraphs do have a topic sentence, some do not. This type of paragraph contains only details or specifics that, taken together, point to the main idea. In paragraphs in which no one sentence clearly expresses the main idea, you must figure it out. Reading a paragraph in which the main idea is unstated is similar to doing a math problem. It is a process of adding up the facts and deciding what they mean together. To solve this math problem you add the numbers and come up with a total sum. [6] I’d been to Los Angeles before, and I’d even performed inside Pauley Pavilion, the basketball arena where the Olympic Gymnastics events were going to be held. But this time the whole atmosphere was different. The American team was staying in dormitory rooms at University of Southern California with runners and swimmers and fencers and cyclists and thousands of athletes from all over the world. You could walk around the campus and see people from China and Brazil and Romania and dozens of other countries who’d all been working just as long and hard as you had and who had the same dreams. And all of them were on different schedules. Some were competing on the first day; others had to wait more than a week. So the cafeteria and infirmary and game rooms were open around the clock, buses were coming and going at all hours, and there were chain-link fences and security guards everywhere to protect us.Here are some skills to find out the main idea of this passage.
