Introductory Sentences Versus Topic Sentences. Because textbook authors often make the first sentence of a paragraph the topic sentence, readers sometimes confuse introductory sentences with topic sentences.

Introductory paragraph. The Introductory paragraph introduces the paper's thesis to the reader. This type of paragraph is used not only to present the topic and organization of the paper but also to grab the reader's attention. When writing the introduction, it is probably best to use the funnel or general-to-specific method.

Here is an example of an introductory paragraph written with the funnel method: The number of cars that are mass produced today is astounding. More than 200 million are produced every year throughout the world. The number of automobiles that are owned by people in America is equally staggering.

To get your paper off to a great start, you should try to have a first sentence that engages your reader. Think of your first sentence as a hook that draws your reader in. It is your big chance to be so clever that your reader can’t stop. As you researched your topic, you probably discovered many interesting anecdotes, quotes, or trivial facts. This is exactly the sort of thing you should use for an engaging introduction.

The typical paragraph found in an essay is the main paragraph, but there are also three special types of paragraphs that are essential to writing an effective essay. These are the introductory, transitional, and concluding paragraphs.

1 Sentence 1 is an introductory sentence rather than a topic sentence, and. 2  Sentence 2 might well be the topic sentence. 3  What would confirm the expectations about the second sentence's role in the paragraph is the third sentence.

Topic Sentence First: In the paragraph that follows, the topic sentence comes first and the remaining sentences pick up on the idea that babies are instinctively social: Infants appear to have a natural tendency to be social.

Supporting Sentences. The body of your introductory paragraph should fulfill two functions: it should explain your first sentence and it should build up to your thesis statement. You'll find that this is much easier than it sounds. Just follow the pattern you see in the above examples.

At this point, experienced readers know two things: 1  Sentence 1 is an introductory sentence rather than a topic sentence, and. 2  Sentence 2 might well be the topic sentence. 3  What would confirm the expectations about the second sentence's role in the paragraph is the third sentence.

The entirety of your paper hangs on that sentence, which is generally the last sentence of your introductory paragraph. In summary, your introductory paragraph should contain the following: 1  an attention-grabbing first sentence. 2  informative sentences that build to your thesis.
