【正确答案】
D
【答案解析】[听力原文] Most American college students need to be efficient readers. This is necessary because full-time students probably have to read several hundred pages every week. They don't have time to read a chapter three or four times. They need to extract as much information as possible from the first or second reading. An extraordinarily important study skill is knowing how to mark a book. Students mark the main ideas and important details with a pen or pencil, yellow or blue or orange. Some students mark new vocabulary in a different color. Most students write questions or short notes in the margins. Marking a book is a useful skill, but it's important to do it right. First, read a chapter with one pen in your hand and others next to you on the desk. Second, read a whole paragraph before you mark anything. Don't mark too much. Usually you will mark about 10% of a passage. Third, decide on your own system for marking. For example, maybe you will mark main ideas in yellow, important details in blue and new words in orange. Maybe you will put question marks in the margin when you don't understand something and before an exam. Instead, you just need to review your marks and you can save a lot of time. What should American college students do to cope with their heavy reading assignments? 细节题。题目问的是美国大学生如何应付繁重的阅读作业。文中第一句话就提及美国大学生必须做一个有效率的阅读者，接下来说道面对每周阅读数以百页的材料，他们不可能每个章节读三四遍，他们需要在阅读第一、二遍的时候就得到关键信息。故选D。本题中“extract”表示“提取，选取”，与选项D中“get key information”属于同义替换。
