Article: What is language for? Some people seem to think it's for practicing grammar rules and learning lists of words -- the longer the lists, the better. That's wrong. Language is for the exchange of ideas and information. It's meaningless to know all about a language if you can't use it freely. Many students I have met know hundreds of grammar rules, but they can't speak correctly or fluently . They are afraid of making mistakes. One shouldn't be afraid of making mistakes when speaking a foreign language. Native speakers often make mistakes and break rules, too. Bernard Shaw once wrote, "Foreigners often speak English too correctly." But the mistakes that native speakers make are different from those that Chinese students make. They are English mistakes in the English language. And if enough native speakers break a rule, it is no longer a rule. What used to be wrong becomes right. People not only make history, but they also make language. But people can only make their own language. They can't make another people's language. So Chinese students of English should pay attention to grammar, but they shouldn't overdo it. When they learn a foreign language, they should put communication first.

Article: Experts say that students usually need eight to ten hours' sleep at night, but most Chinese students do not get enough sleep. Some Chinese parents are usually glad to see their children study late. They will think their children work very hard. But not all parents are happy about this. Once a mother told us that every morning her 10-year-old boy put up one finger with his eyes still closed, begging for one more minute to sleep. Like thousands of students "early birds" in China, he has to get up before six every morning. A report shows that without a good night's sleep, students seem to be weaker than they should be. Many students have fallen asleep during class at one time or another. Too much homework is not the only reason why students stay up late. Some watch TV or play the computer games late into the night. Experts have said that students should develop good study habits. So some clever students never study late, they are able to work well in class.
