     In formal paragraphs you will sometimes see a sentence at the end of the paragraph which summarizes

the information that has been presented. This is the concluding sentence. The concluding sentence is similar

to the topic sentence. They are both general sentences. The concluding sentence can be written in two ways:

     1. State the topic sentence in different words.

     2. Summarize the main points in the paragraph.

     You can understand concluding sentences with this example. Consider a hamburger that you can buy at

a fast-food restaurant. A hamburger has a top bun, meat, cheese, lettuce (生菜), and other elements in the

middle of the hamburger, and a bottom bun. Note how the top bun and the bottom bun are very similar. The

top bun, in a way, is like a topic sentence, and the bottom bun is like the concluding sentence. Both buns

"hold" the meat, onions, and so on. Similarly, the topic sentence and concluding sentence "hold" the supporting

sentences in the paragraph. Let's see how a concluding sentence might look in our sample paragraph about

Wheaton:

     My hometown is famous for several amazing natural features. First, it is noted for the Wheaton River,

which is very wide and beautiful. Also, on the other side of the town is Wheaton Hill, which is unusual because

it is very steep. The third amazing feature is the Big Old Tree. This tree stands two hundred feet tall and is

probably about six hundred years old. These three landmarks are truly amazing and make my hometown a

famous place.

     Notice how the concluding sentence, "these three landmarks are truly amazing and make my hometown

a famous place", summarizes the information in the paragraph. Notice also how the concluding sentence is

similar to, but not exactly the same as, the topic sentence.

     Usually, we begin a concluding sentence with "in conclusion" or "in summary". Remember, not all

paragraphs contain concluding sentences,especially if the paragraph is very short. However, if your paragraph

is very long, it is a good idea to use a concluding sentence.

1. What does the author mainly intend to tell us in this passage?

A. How to write a concluding sentence.

B. What the top bun and the bottom bun are like.

C. Why his hometown is a famous place.

D. To use a concluding sentence in our writing.

2. Why does the author write about a hamburger?

A. Because he can buy a hamburger at a fast-food restaurant.

B. Because a hamburger has a top bun and a bottom bun.

C. Because the top bun and the bottom bun are very similar.

D. Because he wants to explain his main idea in another way.

3. The underlined word "noted" probably means "_____".  

A. written down

B. famous

C. noticed

D. recorded

4. Which of the following statements is TRUE about the passage?

A. A sentence at the end of a paragraph is the concluding sentence.

B. All paragraphs contain concluding sentence.

C. It is a good idea to use a concluding sentence in a long paragraph.

D. The concluding sentence is the same as the to pic sentence.

A. the Wheaton River,Wheaton Hill and my hometown

B. natural features,the Wheaton River and the Wheaton Hill
