17.(A) Attending every lecture. (C) Reading very extensively.
　　(B) Doing lots of homework. (D) Using test-taking strategies.
　　17. M: I’m really surprised you got an “A” on the test. You didn’t seem to have done a lot of reading.
　　W: Now you know why I never missed a lecture.
　　Q: What contributes to the woman’s high score?
　　【答案】A
　　【解析】该题各选项都是某人努力学习的各种方法。各选项意思不重叠，听音时要注意关键信息的识别。对话中男士对女士在考试中得了一个“A”表示奇怪，因为女士看起来也没读很多书。女士回答说Now you know why I never missed a lecture(现在你知道我为什么一节课都不错过的原因了吧)。由此我们可以推理，女士是因为坚持上每一节课而取得好成绩的。故答案为A。
