comparison and contrast 写作方法ppt课件

1、COMPARISON AND CONTRAST,1. Pictures Brainstorming Generating Ideas,2. Writing Strategies,In making contrast, we have to compare. There is no other way to point out the difference, i.e. the contrast. What is of great importance is to know that professional writers frequently use these two strategies

2、to develop paragraphs. There are two major ways of organizing paragraphs of comparison and contrast. One way is to examine one thing thoroughly and then start the other Allabout pattern; The other way is to examine two things at the same time, discussing them point by point Seesaw pattern.,2.1 To ex

3、amine one thing thoroughly and then start the other.,Focus: The aspects examined in the two things should be identical and in the same order. Pattern: A1, A2, A3; B1, B2, B3. （Allabout Pattern） Example: Contrast 1My hometown is quite different from what it used to be. Subtopic: 2Just a little more t

4、hat ten years ago my hometown was a small quiet place. A（1） 3The houses were small and mean. A（2） 3The streets were for the most part narrow and winding. A（3） 3There were few people in the streets and shops.,Subtopic: 2Now, everything has changed. B（1）: 3Looking in every direction from the center of

6、 in the past, my hometown has now transformed into a big city, cheerful, colorful,and prosperous.,2.2 To examine two things at the same time, discussing them point by point.,Focus: Aspects examined in two things should be identical and in the same order. Pattern: A1, B1;A2, B2;A3,B3 (Seesaw Pattern)

7、 Example: comparison. 1Despite their obvious differences in length, the paragraph and the essay are quite similar structurally. A（1）: 2For example, the paragraph is introduced by either a topic sentence or a topic introducer followed by a topic sentence. B（1）: 2In the essay, the first paragraph prov

8、ides introductory material and establishes the topic focus. A（2）: 2Next, the sentences in the body of a paragraph develop the topic sentence. B（2）: 2Similarly, the body of an essay consists of a number of paragraphs that expand and support the ideas presented in the introductory paragraph.,A（3）: 2 F

9、inally, a terminator-whether a restatement, conclusion, or observation-ends the paragraph. B（3）: 2The essay, too, has a device which brings its ideas to a logically and psychologically satisfying completion: the concluding paragraph. C Although exceptions to these generalizations may be observed in

10、modern creative writing,most well written expository paragraphs and essays are comparable in structure. Notes:1) 1,2,3 indicates the level of generality at which a sentence is in the paragraph. 2) C is the short form of conclusion, that is, the concluding sentence.,2.3 An Analysis of An Essay,These
