　　SAT考试写作题目：Writing & Language

　　After reading the passage, choose the answer to the question that most effectively improves the quality of writing in the passage or that makes the passage conform to the conventions of standard written English. Sometimes the question will include a "NO CHANGE" option. Choose that option if you think the best choice is to leave the relevant portion of the passage as it is.

　　To show how a common desk fan cools a person, Rhett Allain, a physics professor and writer for Wired magazine, performed a simple experiment. He wet a paper towel with warm water and wrapped it around a thermometer. Allain wrapped a second thermometer in a dry paper towel, and then he set both thermometers in front of a fan. Initially the fan was turned off. The temperature of the thermometer wrapped in the wet paper towel decreased—at first rapidly, then more slowly—and eventually dropped below room temperature. After the fan was turned on, the temperature of the wet thermometer underwent another rapid decrease. Similarly, the temperature of the thermometer wrapped in the dry paper towel barely changed during the entire experiment. This experiment demonstrated the power of evaporation to cool wet objects, such as a sweaty person, and the role of a fan in making evaporation more effective.

　　Select an answer

　　(A) NO CHANGE

　　(B) By contrast

　　(C) Futhermore

　　(D) Therefore

　　答案：B

　　解析：

　　Choice B is the best answer because it creates the most logical transition within the paragraph's summary of the experiment's data. Given the data provided, it makes sense to present the dry thermometer results as being in contrast to the wet thermometer results.
