CRecently, more than 2,000 high school teachers have been asked about the effect of the Internet on their students. Teachers say the Internet has had a good influence（影响）and a not-so-good influence on this generation.Three quarters of the teachers say the Internet and search tools have had a great effect on their students' research habits and skills. But 87 percent agree that this young generation don't know about hard work and can't stay attentive（注意力集中的）for long. And 64 percent say the Internet does more to distract（使分心）students than to help them in their studies. Many students think "doing research" just means doing a quick search on Google.According to the teachers, one problem is that students trust too much of the information on the Internet. These students have not developed skills to judge the quality of the information. It's something that really has to be taught and paid attention to. It's like everything else. In a world where things can happen quickly, you really need to have a way to step back, think and make judgment about the information you have. And teachers can do a lot to teach that.Another problem is that being able to quickly find information keeps the students from working hard. They become dependent on search tools and do not make enough use of printed books. Many teachers are also afraid that the Internet makes it easy for students to copy work done by others.What does the text mainly discuss about the Internet?

DI am watching my son and hundreds of his classmates, marching in perfect order into the university football stadium（体育场）. Holding back my tears, I search for my son in the sea of people. Suddenly, there he is. I jump to my feet and start waving. Arms flying back and forth above my head, I look like a windmill（风车）, or maybe an airport worker guiding a plane. I see him smile, then laugh as he pulls his camera out of his pocket. He takes a picture of me as he waves back, and then goes to find his seat.What is it about graduations that makes them so moving? Why do most of us women cry as we watch our sons, daughters, grandchildren, nieces, and nephews march in dark robes（长袍）? We cry partly because, no matter how old our children are, and no matter how much they have achieved, in our eyes they are still the little babies we carry around the house to comfort.And, of course, we cry also because something wonderful is ending, and we miss it already. Whatever is on its way to take its place will not be the same. It has been such a gift to have my son go to college close to home. We never have to worry about whether he will be able to make the trip home for a holiday. But this was a time-limited gift. My son will attend graduate school in California. We will talk and text like crazy, and visit as often as we can. But it will not be the same.Why are people gathering in the university stadium?
