Question 1 is based on the news report you have just heard.

News Report One

    You probably think college students are experts at sleeping, but parties, preparations for tests, personal problems and general stress can wreck a student’s sleep habits, which can be bad for the body and the mind. Texas Tech Universityis even offering a class called “Improving Your Sleep Habits”. People suffering from sleep loss are at an increased risk from obesity, psychological problems and car crashes. Students who don’t get enough sleep have poorer attendance and lower grades. On top of all that, （2）a new study published in the journal Learning and Memory finds you are probably better off sleeping than making last-minute preparations for a test. Two hundred college kids were taught to play some unfamiliar video games. Subjects who learned the games in the morning lost some skills when they played again 12 hours later, （1）but they did much better after getting a good night’s sleep. So if you really want to do your job well, don’t forget to get some sleep.

1. What is the news report mainly about?

本道题属于主旨大意题。从原文前半部分我们大概能听出来这是一篇关于睡眠对学生的影响的报道，最后一句话也点出报道主题，想要工作更出色就需要睡眠。文中重点强调的是睡眠的重要性而不是如何改善睡眠习惯，故正确答案为 C。
