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．
