43、如果你不反對的話，我可能就去那里。,Why on earth didnt he send to say that he was ill?We might have helped him.,究竟為什么他不捎信來說他生病了？我們本可以幫助他的。,2.may 和 can,may較正式，而can口語化。,May (might) I speak to you for a moment, professor?,Can(could) I have a cup of tea,mom?,could 有時也可表示推測，因此三者可以互換。,He may/might/could be at the conferenc

44、e.,may not 表示不可能時，重音落在may上。,may not表示不許可時，重音落在否定詞上。,因此在書面語中，為防止歧義，表示不可能用can,t,3 will/would,1.will /would,表請求，指將來，用于疑問句。此時,would,更委婉。,would you mind closing he door?,Will you give her the letter?,2.will /would,表習(xí)慣反復(fù)動作，用于肯定句。,You will have your own way.,你總是想怎樣就怎樣。,3 will/would,will /would,表料想推測，指沒現(xiàn)在或?qū)?/p>
