题目列表(包括答案和解析)
If you take away many sentences from somebody's written work as your own without permission, it's called plagiarism，but if you take the knowledge from a piece of work by another and change the words, then it's not plagiarism. This is the difference between using the Internet and plagiarism. If you are given homework to work out math problems, then you should use your brain without a computer! If the teacher asks you to learn something about a famous literary person, you can use the computer. If you take down the main important information of the task, it’s OK. However, if you run to the computer to do your thinking for you all the time, you don’t exercise your brain and you will forget how to work out a problem. By using a computer, students may get a useful answer fast, to finish homework, but when they have to face an exam, they will not be ready for it.
Though teachers say finding or buying homework answers online is not many in schools, an interview with school students shows only 10% hopes to finish their holiday homework by themselves. They complain that the homework is too much for them to finish. Besides, many of students have to go to all kinds of training classes during the holiday. These take away much of their time for doing homework. So they want to find or even buy answers online or copy each other's homework. Students should learn that being a student is about getting skills, but not just getting quick, cheap "answers" for homework problems. I mean we should use the computer properly.
