【正确答案】
A
【答案解析】[听力原文] Millions of students have been taught a formula that has nothing to do with chemistry. The formula is for writing a five-paragraph essay. First, write an introductory paragraph to state the argument. Then, add three paragraphs of evidence. Finally, write a conclusion. Linda Bergmann is director of the Writing Lab at Purdue University in Indiana. Her job is to help students, including international students, improve their writing. Professor Bergmann has worked with many students who learned this traditional five-paragraph formula. She says international students sometimes have difficulty with this formula if they learned a different writing structure. But just knowing how to write a five-paragraph essay is not going to be enough for a college student who has to write a longer academic paper. As Professor Bergmann points out, the formula is too simple to deal with subjects that require deeper thought and investigation. So what are the qualities that make up a good writing? Karen is executive director of courses in the Institute for Writing and Rhetoric at Dartmouth College. Karen says there are no simple answers—except maybe for one. That is, there is no formula that students can follow to guarantee a well-written paper. In some cultures, students organize their paragraphs to build toward the main idea at the end of the paper. American college students are usually expected to state their thesis at the beginning. And, while students in some cultures use lots of descriptive words, American professors generally want shorter sentences. What can we know about the formula? 短文首段提到…write an introductory paragraph to state the argument... Finally，write a conclusion. 即“开篇写一段导人性质的论点，中间三段列出论据，最后一段做出总结。”所以答案为选项A。其他三项均有细节描述错误，故可全部排除。
