这是一道阅读题,请帮忙找出理由,并给出答案,
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(交流) of ideas and information.It’s meaningless knowing 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 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’re 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,they make language.But a people can only make its own language.It can’t make another people’s language.So Chinese students of English should pay attention to grammar,but they shouldn’t overdo it.They should put communication first.
