农村文化建设意式风格Comparison and contrast is a method that is often ud by writers to analyze the similarities and differences between two subjects. To compare is
to bring out the similarities between two things，and to contrast，which is a form of comparison，is to emphasize the differences between them. As a result，we can understand the two subjects better than we would do if we just examine the two individually.
In writing a comparison and contrast essay，you may emphasize either the similarities or the differences between the two subjects，or if you like，you may include in your essay both the similarities and differences. No matter what you may emphasize in your essay，remember you should make a point in your essay，that is，there should be a purpo for making the comparison and the contrast. If the two items are too similar or too different，there won’t be any point in comparing or contrasting them.

The organization of a comparison and contrast essay：
A .How to introduce a comparison and contrast essay
You can introduce your comparison and contrast essay by explaining clear your purpo for making the comparison and/or contrast. You can also prent the background information that promotes you to write the essay.
B. How to organize the body of a comparison and contrast essay：
辐射损伤When you come to the body of a comparison and contrast essay，you should follow the following two steps：
Identifying the points：If you don’t know what points to compare and/or contrast about the subjects，you can create a list of potential points for each of the subjects. Then you can rearrange the points.
2. Choosing an effective pattern to organize the similarities and differences. a）The subject-by-subject pattern：to prent each of the two subjects parately，that is，to prent first about one of the subjects，covering the points completely，then proceed to the other subject，also covering all the
points completely. In general，this way works better in short essays where few aspects are considered，or where the writer’s interest is in the whole. Its pattern is like the following：
b）The point-by-point pattern：to discuss the two subjects for each point of comparison and contrast，that is，you write about the first point in terms of the similarities and differences between the two subjects，then proceed to the next point，and so on. This way is preferable in long essays where many aspects are mentioned，for a long discussion of the various aspects of one item puts too much burden on the reader’s memory. Its pattern is like the following：
c）The sim-diff pattern：The writer puts all the similarities between the subjects together and all the differences together. This technique is suitable for tho subjects who similarities and differences are more balanced. In an essay using this pattern to organize the body part，the whole essay will be arranged in the following way：
Introduction
Similarities
Differences
Conclusion
C. How to end a comparison and contrast essay：
Your conclusion should help your readers draw conclusions. You may propo an action，stimulate the reader or make a generalization. You can also restate your purpo in a fresh way.
