14、子主语The accident和谓语动词avoid之间是被动关系,结合句意可知答案为D。情态动词+ have done结构:1.“must + have + 过去分词”表示对过去发生的事情或状态进行推测,语气比较坚定,通常只用于肯定句。It must have rained last night,for the ground is wet.2.“can / could + have + 过去分词”表示对过去某种情况的怀疑或不确定。can和could一般用于否定句和疑问句,could的语气较can弱。He cant have finished the work so soon.3.“may /
15、might + have + 过去分词”表示对已发生的动作或存在的状态进行不肯定的推测,might的语气比may弱一点。这种结构主要用于肯定句和否定句,疑问句改用can或could。They may not have known it beforehand.4.“need + have + 过去分词”表示过去做了不必做或不需要做的事情,或过去做某事纯属多余。I neednt have bought so much wineonly five people came.5.“should / ought to + have + 过去分词”表示过去本该做某事但没做,其否定式表示过去不该做某事但做了,

19、本来有必要做而未做”;“neednt have done”指过去本来没必要做而做了。根据上一句时间状语“yesterday”可知本句指的是过去发生的事。结合第二句“because my director was there(我的主管)在”可推断出,我本来不必要去。故选D。17Students _ remain in their seats until all the papers have been collected according to the regulation.Awould Bshall Cwill Dcould学生们必须呆在自己的座位上,直到所有的试卷都被收回。根据句意,“学生
20、们呆在自己的座位上”是一项规定。shall 可表示某种规定或义务,用于第二、三人称的句子中。而其他情态动词无此用法。故正确答案为B。18While it wasnt the goal of the trip, I was rewarded with fresh insights, ones that _ to me during the regular course of business.Amight never happen Bcould never have happenedCshould not happen Dneednt have happened考查虚拟语气。虽然这并不是这次旅行
21、的目的,但我得到了一些新的领悟,那些领悟在我的日常生活中是本不可能发生的。此处考查虚拟语气,“我得到新的领悟”发生在过去,故此处是与过去事实相反,应用could/might/would/need/should+have done,“本不可能发生”是could never have happened,故选B项。本题考查“情态动词+have done”的虚拟语气,其常用表达有:could have done本能做某事而未做 couldnt have done不可能做了某事should have done本应该做某事而未做 shouldnt have done本不应该做某事而做了would have
22、 done本会某事而未做 wouldnt have done本不会做某事而做了need have done本需要做某事而未做 neednt have done本不必要做某事而做了19Sorry, Mum! I failed the job interview again.Oh, its too bad. You_ have made full preparations.Amust Bcan Cwould Dshould考查情态动词+have done结构。对不起,妈妈,我面试又失败了。噢,那太糟糕了,你应该做好充分准备的。A.must必须;B.can可以;C.would将会;D.should应
23、该。这里是情态+have done的结构的虚拟语气,can+have+done”表示对过去行为的怀疑,用于疑问句,译成“可能做过吗?”;could+have+done,表示对过去事情的假设,意思是本来能够做某事而没有做;must+have+done”表示对过去事情的肯定推测,译成“一定做过某事”,该结构只用于肯定句;should+have+done意思是“本来应该做某事,而实际没做”。故选D【名师点睛】情态动词是一种本身有一定的词义,表示说话人的情绪、态度或语气的动词,但它不能单独作谓语,只能和其他动词一起构成谓语。情态动词是每年高考的热点也是难点,每年单项填空题必考一题。考点集中在:情态动词

A. can可能,可能性,表示可能性时,常用于否定句和疑问句中,且有时还带有“惊奇、不相信” 等感情色彩。B. should 应该; C. may也许,表示可能性时常用于肯定句中,不用于疑问句中。D.must常用于肯
25、定句中表推测,“一定”的意思;本题是强调句型的一个变式:强调其特殊疑问句how的形式。根据前句“斯密斯先生几乎是很准时”可推测出“怎么可能开会迟到呢?”。根据句意可知,用于疑问句中的“可能性”且有不相信的色彩,四个选项只有“can”符合题意。故选A情态动词就是表示说话者对事情的一种看法,也就是一种语气。情态动词的用法一直是命题者常设置的考点和重点,平时要加强记忆。21If we had paid enough attention to the issue of the heavily-overloaded vehicles, the tragedy of the collapse of an
26、overpass in Wuxi _ avoided.Ashould Bcould be Cshould have been Dcould have been考查情态动词用法。如果我们对超载车辆问题给予足够的重视,就可以避免无锡立交桥垮塌的悲剧。本句为“情态动词+have done”结构,结合句意表示“本来可以;本来能够”应用could have done结构,且主语与谓语动词avoid构成被动关系,故应用be done形式。情态动词+have done的结构和用法有以下几种:一、must have done sth.“一定做了某事”。表示对过去事情的较有把握的推测,这时只能用在肯定句中,“肯
27、定/必须已经干过”,在否定句和疑问句中用cant或couldnt或can/ could,例如:1.From what you said, she must have told you all about it. 从你的话看,她一定告诉了你所有的事情。二、can/could have done sth.本来能够做某事,而实际上未做;1.But we could have done it all so much better. 但是,我们本可以把这一切做得更好。三、cant/couldnt have done sth.不可能做过某事;1.
