Advice to Freshman You have been at Furnell University for two weeks now. As usual, you need enough time to sleep and eat. You also want to spend time with your new friends and get some exercise. But, after the first two weeks of classes, you have probably concluded that there isn't enough time to do all these things, because you also have to attend classes, go to labs, do assignments and write papers. Soon you will be in a situation like this one: You are going to have a quiz in your ten o'clock class. You studied for it until 3 A. m. You also have an eight o'clock class. Should you sleep late and skip the eight o'clock class? To some extent the answer depends on the professor of the course. Some instructors announce that they require attendance. In that case you really should go to class. Some don't say anything. In that case you have to decide. Once in a while it is better to stay in bed and sleep than to get so tired you cannot think. However, it is not a good idea to skip class more than a few times. If you have to skip a class, ask another student for the class notes, announcements and the assignment. Also, come to the next class prepared. If you miss class because you are sick, tell the instructor afterward. He or she may let you make up the work. If you have an important appointment, tell the instructor about it before you miss the class. Here is another common problem. You took the quiz. Even after studying very hard, you could not answer all the questions. In high school you always got every answer right. What went wrong? Nothing. High school work is easy, so a good student is supposed to get a perfect score. In college the teacher wants to challenge even the best students. Therefore, almost nobody answers every question correctly. But maybe there were some very basic ideas in that course you did not understand. Go see the teacher during his or her office hours. Most teachers will gladly explain things again. Of course, they will not be pleased to repeat what they said in class to someone who skipped class. Maybe you really should get up for that eight o'clock class! According to the article, a good student in college must ______.
A.
go to every class, no matter how he/she feels
B.
go to class unless there is a good reason not to
C.
stay in the dormitory and study
D.
make excuses to the teacher

【简答题】阅读下面的短文,然后回答问题: 人为什么长两只耳朵呢?人长两只耳朵可以帮助我们确定声源的位置.声音从声源处传到我们耳朵时,并不是同时到达我们两只耳朵的.若声源在人的左边,声音就会先到达左耳,再到达右耳,所以两只耳朵收到声音的先后、强弱都不会完全相同,靠这种差别我们就能确定声源的位置了,这叫双耳效应. 小明等同学做了一个实验.当小明被蒙上眼睛时,另一个同学在他的正前方拍手,他却指向正后方,另外的同学...
