【正确答案】 A

【答案解析】[听力原文] Moderator: Faced with a wide variety of goods in the shopping mall, have you ever been crazy for the choice overload problem? Today, we are honored to have Sheena Zyengar, business professor from Columbia University, to give us a lecture on how to make choice easier. Sheena Zyengar: Thank you! Do you know how many choices you make in a typical day? Do you know how many choices you make in a typical week? I recently did a survey with over 2,000 Americans, and the average number of choices that the typical American reports making is about 70 in a typical day. There was also recently a study done with CEOs in which these scientists followed CEOs around for a whole week. And they simply documented all the various tasks that these CEOs engaged in and how much time they spent engaging in matting decisions related to these tasks. And they found that the average CEO engaged in about 139 tasks in a week. Each task was made up of many, many sub-choices of course. 50 percent of their decisions were made in nine minutes or less. Only about 12 percent of the decisions did they make an hour or more of their time. Think about your own choices. Do you know how many choices make it into your nine minute category versus your one hour category? How well do you think you're doing at managing those choices? Today I want to talk about one of the biggest modern day choosing problems that we have, which is the choice overload problem. I want to talk about the problem and some potential solutions. Now as I talk about this problem, I'm going to have some questions for you and I'm going to want to know your answers. So when I ask you a question, since I'm blind, only raise your hand if you want to burn off some calories. Otherwise, when I ask you a question, and if your answer is yes, I'd like you to clap your hands. So for my first question for you today: Are you guys ready to hear about the choice overload problem? What is the purpose of the survey done with CEOs? 该题考查对CEO做的研究的目的。在对CEO的调研中，科学家们记录下CEO做的各项任务及在每项任务中做决定花费的时间。故A正确。 虽然CEO在商务会议上也可能做决定，但调研侧重的是CEO做决定花的时间，而不是在会议上花费的时间，故排除B。C“了解他们出差旅行的频率”及D“了解他们工作压力的强度”均未在录音中提及，故排除。

【正确答案】 A

【答案解析】[听力原文] What is the focus of Professor Sheena Zyengar's speech? 录音首尾处均提到，演讲的主要内容是关于选择过多造成的问题及其解决方案，有解决方案的人能让选择更容易，故A正确。 B“让工作时间更有效率”，做选择花费的时间确实会影响到工作的效率，但这不是演讲的重点，故排除B。C“让购物更加方便”，D“更独立地做决定”，演讲者没有提及购物的问题，也没有说要独立地做决定，故排除C、D。

【正确答案】 C

【答案解析】[听力原文] How will the audience respond to the speaker's question if their answer is 'yes'? 该题问面对演讲者的问题，听众如何互动，在录音最后，演讲者让听众通过拍手的方式来表示yes，故C为正确答案。 A“通过说话”，演讲者没有让他们用语言来表达yes，而是用拍手的方式，故排除A。演讲者是个盲人，眼神交流和举手她都看不到，这样的互动是无效的，故排除B、D。
