Most paragraphs have a "topic sentence" which expresses the central idea. The remaining sentences in the same paragraph expand or support that idea. It has been estimated that between 60-90% of all expository(阐述，说明) paragraphs in English have the topic sentences placed at the beginning of the paragraphs. Always pay special attention to the first sentence of a paragraph; it is most likely In give you the main idea.Sometimes, though, the first sentence in the paragraph does not have the feel of a main idea" sentence. It does not seem to give us enough information to justify a paragraph. The next most likely place to look for the topic sentence is the last sentence of the paragraph. Take this paragraph for example:"Some students prefer a strict teacher who tells them exactly What to do. Others prefer to be left to work on their own. Still others like a democratic type of class. No one teaching method can be devised to satisfy types of class at the same time."Remember that the opening and closing paragraphs of a passage or chapter are particularly important. The opening paragraph suggests the general direction and context of the piece, while the closing paragraph often summarizes the very essence of what has been said. What does the author want to tell readers Readers should（）to [he first and closing sentences of a paragraph.

Once you decide to choose a topic to write an effective paragraph, the first key to write a good topic sentence. The topic sentence does two things: it tells the reader what the topic of the paragraph is, and it says something about that topic. What the topic sentence says about the topic is called the controlling idea; it is the point of the paragraph, and every other sentence in the paragraph must be related to this point.The topic sentence should be the first sentence in the paragraph unless there is some special reason for placing it somewhere else. When the topic sentence is the first sentence of the paragraph, the reader immediately knows what you intend to discuss. In addition, you have the topic sentence to refer to as you make each of the other sentences in the paragraph, so that you can be sure that each of those sentences refers to your subject and to your controlling idea. Sometimes experienced writers put the topic sentence at the end of the paragraph or even in the middle to create some kind of special impression; but while you are still learning to write effective paragraphs, it is safest to put the topic sentence at the beginning unless you have a special reason for doing something else.A good topic sentence is a clear, definite statement with a limited and special topic and a limited and specific controlling idea. It is usually placed at the beginning of the paragraph. Now that you have had some practice in identifying and constructing good topic sentences, we are ready to look at some of the basic principles that govern the composition of effective paragraphs. The topic sentence should often be placed in the front of the paragraph,（）
