They are very intimate with each other sometimes. Some people think too much intimacy has a bad influence. It takes lovers too much time and energy. Then how about their studies? Furthermore, their intimacy can aisc distract their own as well as other students' attention from study. Campus should be a place for study and should maintain an atmosphere of learning.On the other hand, other people believe it is OK. Pursuing love is all right to students on campus and intimacy is a natural expression of love. Some scholars of law hold that friendships and appropriate intimacy are an important pard of student development. A sociologist says, "Students' right to self-expression should be respected."In my opinion, what all people should do is just leave it as it is. University students are adults, and they can handle their own affairs well enough. However, they have to admit that school is a place where people receive an education and their main task is to study. Therefore, students are expected to behave themselves in proper ways.经典谚语积累Genius is nothing but labor and diligence. 天才不过是勤奋而已。

She told me that was because someone thought everyone work most of the time, and friends might take up your time, so they were thieves of your time. I thought it was funny. I even wanted to ask them, “Don’t you think you are happy when you are staying with your friends? Isn’t happiness an important thing?”If one lives without friends, I can’t imagine his life in the world. And if one has good friends, even only one, I think he may be the luckiest onein the world.

Since then, millions of children have grown up in front of the set. Many people now worry about the effect of TV on the young. They wonder if television should be allowed to go on. Many parents wish that there had never been such an invention. Why are they so afraid? Is television really harmful?Like almost anything else, television has its good as well as bad sides. It makes us informed of daily news. It tells us product information. It lets us know of the outside world. It provides lessons for learners. And it has brought joy and interest into the lives of the old, the sick, and the lonely. Without it, some of these people would have little pleasure in the world.Unfortunately, some television programs have been extremely harmful to the young. Children do not have enough experience. They do not realize that TV programs often show an unreal world. Commercials tell lies in order to sell products that are sometimes bad or useless. Children believe them and want to imitate what they see on TV. They believe that they will make more friends if they use a certain soap----or some other product. They believe that the murders on TV screens are normal and acceptable. By the time theyare out of high school, most young people have watched about15，000 hours of television, and have seen about 18,000 Dviolent deaths. If they see violent deaths every day, how can they be shocked by murder in real life?Television has certainly changed our lives and our society. Along with its good points, it has brought many problems. We must find a solution to these problems because----whether we like it or not----television is here to stay.经典谚语积累Empty vessels make the greatest sound. 实磨无声空磨响，满瓶不动半瓶摇。
