I_____you a beautiful present for your birthday, but I was short of money at that time. A. would buy          B. had bought C. would like to have bought  D. must have bought 参考答案与简析 1.C。will在此表示“应诺”。 2.B。May I...?中的may用以表示“允许、许可”。 3.A。shall 用于第二、三人称的肯定句或否定句,表示说话人的意愿,有“命令、警告、威胁、强制、允诺、决心”之意。 4.C。may表示“允许”。回答may引起的问句,肯定式一般用 Yes, of course./Yes, certainly./Sure./Yes, you may.否定式用No, you mustn’t. 5.A。needn’t表示“不必要”;mustn’t表示“禁止”;wouldn’t表示“拒绝”。 6.A。can表示“可能性”,通常用于否定句或疑问句中,且有时还带有“惊奇、不相信”等感情色彩。 7.B。must表示说话人的主观愿望,而have to多表示客观需要。 8.D。would have done表示对过去已发生的事情的推测,表示“可能……”。 9.B。shouldn’t have done表示“过去本来不应该做某事而事实上已经做了”。 10.D。should/should not+do,表示“(现在)应该/不应该……”。 11.B。Let’s do sth.表示“建议做某事”,含听话一方在内,故用 shall we。如果用Let us do sth.结构,则用will you?表示请求对方允许。 12.A。情态动词dare的过去式为dared,常用于否定句、疑问句及条件句中,没有人称和数的变化,否定式是在dare后接not,再接动词原形。dare作为实义动词时,有人称和数的变化,构成否定句时,前要加助动词,后接带to或不带to的动词不定式。13.D。need作为情态动词,一般用于否定句、疑问句及条件句中,后接动词原形。表示“现在不必干某事”,用need not do sth.;表示“过去不必干某事”,用need not have done。need作为实义动词,与其它动词用法相同,用于否定句或疑问句要加助动词。 14.C。“must have done”结构,表示对过去发生情况的肯定推测。 15.B。can’t have done,表示对过去发生情况的否定推测,意为“不可能已经……”。 16.B。must have done表示对过去发生情况的肯定推测,句中带有明确的过去时间状语,故附加疑问句用“didn’t they”。 17.C。should/ought to have done表示“本来应该做的事而事实上并未做”。根据上下文,句中省去了seen her。 18.C。回答must引起的问句,否定回答用needn’t或don’t have to. 19.C。I’m sorry/surprised/disappointed之后的从句中,有时采用虚拟语气should do来表示“难过、惊奇”等情绪。 20.B。“Will you...?”在此表示邀请或请求,回答时如果用 I won’t 显得极不礼貌,也不符合下文; My brother is... me.表示“我不能来的原因”。 21.C。此题表示与过去事实相反的假设,主句用would have done,从句用had done,此处用了倒装的省略形式,即省去if, had提到句首。 22.D。参见上题。 23.D。此题表示与现在事实相反的假设,主句用should/would/might/could+do. 24.D。参见注17。 25.B。would在此表示过去的习惯、习性、倾向等,意为"常......",通常与often,sometimes,for hours等表示时间的短语连用。 26.C。would rather do sth. than do sth.为固定搭配,“宁愿做……而不愿做……”。 27.D。It’s(high/about) time that从句的谓语动词多用过去式,有时也可用should do。 28.C。Could I...?问句表示委婉的请求,若允许对方,应用can来作答,而不用could。 29.A。在It’s important/surprising/desirable/strange/necessary/no wonder/a pity/a shame+that 从句中,从句谓语动词用(should ) do。 30.B。wish后接从句,如果从句指将来的愿望,谓语动词用would/could+do;如果表示过去未能实现的愿望,从句谓语动词用had done;如果表示现在未能实现的愿望,从句的谓语动词用过去式,be动词用were。 31.B。could have done表示对过去发生情况的可能性推测。 32.D。must be using表示此刻“一定正在使用……”。 33.B。在suggest, demand, request,require(要求),order(命令),insist(坚持),advise(劝告)等动词之后的宾语从句中,谓语动词要用(should) do,同时还应注意语态。 34.C。as if引导的从句,如果所说内容与事实不相符时,常用虚拟语气。此题是一种自然现象,故应用一般过去时。注意比较It seems/looks as if it is going to rain.(看起来天将要下雨。) 35.A。参见注33。 36.D。在if only引导的感叹句中,谓语动词的形式与wish后宾语从句中谓语动词的形式一样。 37.B。参见注29。 38.C。will在此为情态动词,表示“意愿”。 39.A。根据上下文可知句意为“他不愿意帮助别人,但也许他会帮你的忙”。用“might”,表示“可能性”比较小。 40.D。can表示能力时可用be able to代替。但can只有一般时和过去时,be able to可用于各种时态。如果表示“过去有能力并成功地做成了某事"时,要用was/were able to,不用could。 41.D。参见注3。 42.C。mustn’t在此表示“禁止”。 43.C。参见注 30。 44.D。参见注33。 45.A。would like sb. to do sth.意为“想要某人做某事”。为固定搭配。 46.A。mustn’t be doing与always连用,表示“一定不要总是在做……”,含有“埋怨、不满”等感情色彩。 47.D。该题表示与现在事实相反的假设,从句谓语动词用过去式,be用were,主句用would do。 48.C。该句叙述当时的真实情况,故用C。 49.A。该题中as if引导的从句表示与过去事实相反的假设,从句谓语动词用had done。 50.D。but for(要不是)引导的介词短语,相当于if it hadn’t been the fog。 51.A。该题中suggest意为“表明、暗示”,这时其后宾语从句中谓语动词用陈述语气。 52.B。在advice,demand,idea,order,plan,suggestion等名词后的同位语从句或表语从句中要用虚拟语气,其谓语形式为“(should)do”。 53.D。句中的must表示对现在的状态或现在的事实进行推测,故后面的附加疑问部分用一般现在时。 54.B。insist意为“坚持说”时,后面的宾语从句中谓语动词用陈述语气,即如果从句动作与主句动作同时发生,从句谓语用一般过去时;如果从句动作先于主句动作发生,则从句谓语用过去完成时。意为“坚决要求”时,后面宾语从句中谓语动词用“(should) do”。 55.B。本句属于隐含式虚拟语气。句中without短语相当于一个与过去事实相反的虚似条件句,故选B。 56.B。本题是对将来情况的一种假设。英语中,如果虚拟条件句的谓语部分有should,had或were时,可把if省去,而把should,had,were放在从句主语前,构成主谓部分倒装。 57.B。can在本句中指一种理论上的可能性。 58.C。本题为与过去事实相反的假设,在以otherwise引导的并列分句中用虚拟语气,时间概念可由上下文看出。 59.D。or引出的一个分句表示对过去的情况进行假设,故用would have done。 60.C。从 but 引导的分句可看出,前一分句是与过去事实相反的假设。
