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.
【小题1】If you want to look up some information about something or somebody, you____.

Reading is a good habit. There are hundreds of skills to help you read much in a short time. Here are two skills that I think are especially good.
Preview(预览)---if it’s long and hard. Previewing is especially useful for getting a main idea of heavy reading like long articles and reports.
Here’s how to preview.
●Read the first two paragraphs(段落) and the last two paragraphs carefully.
●Then read only the first sentence(句子) of the other paragraphs.
Previewing doesn’t give you everything. It stops you from spending time on things you don’t really want or need to read.
Skim(略读)----if it’s short and simple. Skimming is a good way to get a main idea of light reading ---like news about popular sports and stars.
Here’s how to skim.
●Get your eyes to move fast. Look through each line.
●Pick up only a few important words in each line.
Everybody skims differently. You and I may not pick up the same words when we skim the same piece, but we’ll get the main idea of the news or article.
