explores the main idea explicitly and concretely,with 3.第一个写作常识has sound internal structure.The

qualities that indicate sound internal structure are unity,coherence,and completeness.

4.怎样做到内容一致An excellent way of achieving unity is by means of the topic sentence.Properly used,the topic sentence forces the writer to adhere to and to sustain the

point he is trying to establish

5.标题句① the topic sentence properly used can achieve unity in the paragraph,which indicate the importance of the topic sentence;②the topic sentence

6.第二个写作常识 In short,a good topic sentence has a limited subject and a sharp focus,namely,a good topic sentence is not too general nor too narrow.A topic sentence that is too general requires much more than a paragraph to develop it.A topic sentence

that is too narrow leaves little to be said in the rest of the coherence is connection and consistency.A coherent paragraph is one in which all the sentence are related logically and grammatically to make a whole that allows the reader to follow the writer’s train of thought step by step

8．第三个写作常识 Just as topic sentences help readers follow our ideas,other signals also help them understand what we have to say.When we write and when we revise,look for the areas that seem choppy or unconnected—that

lack coherence.We can establish better coherence by using the following devices:pronoun reference,repetition ,and in a paragraph means that the topic is adequately developed by details,explanations,definitions,evidences,and the like,so that the reader is not left with only a fuzzy idea of what the writer means

3Deductive Pattern (演绎法概念)：In developing a paragraph by means of the deductive pattern the writer begins with a generalization(the topic sentence) and proceeds with specific elaboration or application of the general idea.

4Inductive-deductive Pattern(归纳演绎法)：As the name indicates, in developing a paragraph by means of inductive-deductive pattern the writer first presents particular instances and a resulting generalization, then applies the generalization to a new instance.5第五个写作常识：Sequences of development are not independent of types of development. The most important sequences of development are general to particular, particular to general, climactic, chronological, and spatial.

6Climactic Sequence (层递顺序)：In a climactic sequence, the most intense or highest point of interest is saved for the final sentence, which may be, but is not necessarily, the topic sentence.

7.Chronological Sequence (时间顺序):A chronological sequence is one in which earlier things precede later things; items are listed in the order in which they occur in time. The most obvious use of a chronological sequence is in telling a story.

8Spatial Sequence (空间顺序)：A spatial sequence is used in descriptions of various types. It starts the reader at a particular point and then moves logically in some direction, from one place to another.

9第六个写作常识：The type of development is the way in which the main idea is supported-by details, definitions, statements of cause and effect, and so on.

10段落展开方式：Among the most important types of paragraph development are development by detail, comparison and contrast, process, classification and partition, cause and effect, definition, and mixed development.
