课时分层作业(十七)Ⅰ.单句语法填空1．If you have some trouble getting(get)along with your friends，you can write to them.2．This is important because the more you speak English，the better(good)your English will become.3．Struggling for our dreams，as the headmaster addressed at the meeting，offers us a sense of responsibility.4．In a way I can see what you mean，even if I don't share your point of view.5．We have to write a description(describe) of the street where we live and give it to the teacher tomorrow.6．Compared with/to natural disasters，such as typhoons，floods and earthquakes，humans are very weak.7．After a month of training，he became equal to the work as a bus driver.8．If you are talking to someone senior to you，you'd better be polite.9．She demanded to_see(see) the headmaster immediately to settle the problem.10．I'd like to read books related (relate) to western culture and custom.Ⅱ.阅读理解Many people believe that there is one form of their language that is more correct than others.For example，they may believe that British English is more correct than other varieties；or that written English is more correct than spoken English；or that standard spoken forms are more correct than dialect forms.Often this belief is supported by reference books on grammar，usage guides or dictionaries：If something goes against a rule in a grammar，or if the word isn't in the dictionary，it “must be wrong”．Since the reference books are often based on observation of the standard written language，the argument is really circular：These books will naturally describe standard usage，because that is what they are for；but this does not mean that there is anything wrong with other kinds of usage less often described.A better way of looking at things is to say that usage is “correct in its place”．Standard American English is correct in America，British English is correctin Britain，spoken grammar is accepted in casual speeches，and formal written grammar is employed in formal writing.The only forms that are wrong in all contexts(语境) are learners'errors.For example，“I have forgetting the your address.”or “One of your chairs are broken.”This means there is no answer to the question：“What kind of English should learners study？”It depends on their purposes.For many learners，the best model is British or American English.Neither of these is “better” than the other，and they are both used and understood worldwide.People are also worried about language change.If younger people “break” the rules that older people have learned，or use language in new ways，older people often feel disturbed：They are concerned that younger people no longer know their grammar，and that the language is going downhill.This is a needless worry：Change is natural and inevitable；it cannot be stopped，and it does not generally affect a language's efficiency as a communicative tool.A great deal of modern English grammar would have been wrong three hundred years ago，and will perhaps be wrong again three hundred years from now.【语篇解读】不同的语境决定了不同的语言使用方法，所以作者认为，没有所谓“一定正确”和“一定错误”的语言。
