I have to do my homework.抱歉，我不能，我得做作业。1. Which sounds more polite to you?Can you do the dishes?Could you please do the dishes?探究归纳：1.虽然情态动词can和could均可用来提出要求，但could要更为委婉客气。Could you please.?是一个礼貌委婉地提出要求的句式，其后只要添加所要求的内容即可。肯定回答用“Yes, sure./Certainly”回答用“Sorry，I cant”.-我可以出去打篮球吗？ -当然可以，但你必须先完成作业。 【探究小结】：在表示请求帮助或请求允许的疑问句中，常用could代替can，以表示礼貌，委婉或者不确定的语气，而can则不具备这些语气。这种情况下不能把could看作can的过去式。以上两句中用could是为了表示礼貌的请求。表示请求帮助或者请求允许时，除了can和could之外，还可以用may，句子的表达方式各有不同，可以用不同的方式来表示同一个概念。例如：Could/ Can/May I use your car for a day?I wonder if I could use your car for a day?Do you mind if I use your car for a day?对于句所作允答可以各种各样，如同意可以说Yes或Sure或C二天旅游，还可以说Yes,please或Of course(you can/may).或Thats OK/all right.如果不同意可以说Im sorry you cant.或Im really sorry,but I have to use it today.要避免说No,you cant.这样显得很没有礼貌。否定回答通常用委婉语气。对于第所作回答可以说Never mind./ Not at all. 表示“不介意”。不能用Yes./Sure./Of course./Certainly.等。观察下列句子：【合作探究】二 borrow, lend, keep辨析单词意义常见搭配例句borrow借（进）Borrow sth from sb向某人借某物We can borrow this book from our Teacher.我们可以从老师那借这本书。lend借（出）Lend sb sth = lend sth to sb借某物给某人You mustnt lend this book to others.你不能把这本书借给别人。keep保留，引申为“借用”“Sb keep sth + 时间段”表示“某人借某物多长时间”，也可与how long 连用You can keep this book two weeks.这本书你可以借两个星期。注意：不管是借入还是借出，都是就主语而言的。此外，borrow 和lend 均为非延续性动词，若表达借某物多长时间，不能用borrow 和lend，而要用keep，意为“保存；保留”。练一练1.-How long may I _ your dictionary?-For one week.But it mustnt _ to others.
