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 will happen when students depend too much on search tools?
A、They won't make good use of books.
B、They won't copy work done by others.
C、Their studies will be greatly improved.
D、Their attention to things will last longer.
