12、would的基本用法
(1)would作为will的过去式,可用于各人称,表示过去时间的“意志”或“决心”,如:He promised
he would never smoke again. (2)在疑问句中,用于第二人称,表示说话人向对方提出请求或许问对方的意愿时,比用will的气更加婉转,如:Would you like some more coffee? (3)在日常生活中,学用“I would like to…”表示“我想要”或“我愿意”之意,以使语气婉转,如:I would like to do Ex.2 first. (4)would可以表示过去的习惯动作,比used to正式,并没有“现已无此习惯”的含义。如:Last year our English teacher would sometimes tell us stories in English after class. / During the vacation he would visit me every week. (5)表料想或猜想,如:It would be about ten when he left home./ What would she be doing there?/ I thought he would have told you about it.
13、used to, had better, would rather的用法
(1)used to表示过去的习惯动作或状态,现在已不存在,在间接引语中,其形式可不变,例如:He told us he used to play foot ball when he was young. 在疑问句、否定句、否定疑问句或强调句中,可有两种形式。疑问句:Did you use to/ Used you to go to the same school as your brother? 否定句:I usedn’t to / didn’t use to go there. (usedn’t 也可写作usen’t);否定疑问句:Usen’t you to/ Didn’t you use to be interested in the theatre? 强调句:I certainly used to/ did use to smoke, but it was a long time ago.;其反意疑问句或简略回答中,也有两种形式:She used to be very fat. didn’t she?/ use(d)n’t she? Did you use to play chess? Yes, I did./ Used you to get up early in the morning? Yes, I did./ used to. (2)had better意为“最好”,后接不带to的不定式,例如:---- We had better go now . ---- Yes, we had (we'd better/ we had better)./ Hadn’t we better stop now? (Had we better not stop now?)/ I think I’d better be going. (用于进行时态,表“最好立即”)/ You had better have done that (用于完成时态,表未完成动作) 注:had better用于同辈或小辈,对长辈不可用。(3)would rather意为“宁愿”,表选择,后接不带to的不定式,例如:I’d rather not say anything./ Would you rather work on a farm?/ ---- Wouldn’t you rather stay here? ---- No, I would not. I’d rather go there. 由于would rather表选择,因 而后可接than,例如:I would rather work on a farm than in a factory. / I would rather watch TV than go to see the film/ I would rather lose a dozen cherry trees than that you should tell me one lie./ I’d rather you didn’t talk about this to anyone. (句中的 'd rather不是情态动词,would 在此是表愿望的实义动词)
