资料题：If a student doesn't understand an important part of the lesson, he or she（　）。

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 until3 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 g 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 that 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 to 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!
