13.If you take away many sentences from somebody's written work as your own without permission,it's called plagiarism(剽窃),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(大脑)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.
