Asympathy Btheme Cobject Dpoint 【解析】 考查名词辨析。句意：依你看，如果他都不努力帮他自己，那我们帮他的目的是什么呢？whats the point of.表示“的目的(意图)是什么？”，而sympathy同情，theme主题，object物体，与句意不符。 【答案】 D,观察下列从Listening and vocabulary中选取的句子，体会“情态动词have done”的用法。 1The dinosaurs may have stopped evolving，and been unable to adapt to changes in the climate. 2They might have killed each other. 自我总结 “情态动词 ”结构一般有两个主要用法：一是表示对 发生的动作或状态的 ，二是表示对 发生的动作的遗憾或责备。 【答案】 have；done；过去；推测；过去,情态动词have done 1“musthave done”表示对过去发生的事情的肯定推测，意为“一定做过某事”，该结构只用于肯定句中。 You must have been mad to drive so fast. 你车开得那么快，一定是疯了。 It must have rained last night，for the ground is wet. 昨晚一定下雨了，因为地面还是湿的。,2“can/couldhave done”用于否定句表示对过去发生事情的否定推测，意为“不可能做过某事”；用于疑问句表示对过去行为动作的怀疑，意为“可能做过 吗？”。 Mr.Smith cant have gone to Beijing，for I saw him in the library just now.史密斯先生不可能去北京了，我刚才还在图书馆见过他。 I met him at school yesterday afternoon，so he couldnt have attended your lecture.昨天下午我在学校遇上他了，因此他不可能参加你的讲座。 There is no light in the room；can they have gone out? 屋里没有灯，他们可能出去了吗？,【提示】 “couldhave done”用于肯定句，表示对过去事情的假设，意思是“本来能够做某事而没有做”。 He could have passed the exam，but he was too careless. 本来他能够通过考试，但是他太粗心,3“may/might have done”表示对过去发生的事情的可能性推测，意为“可能已经做了；也许已经做了”，多用于肯定句。might have done的可能性比may have done的还要小。 What has happened to Tom? 汤姆发生了什么事？ I dont know.He may have got lost. 我不知道。他可能迷路了。 She might have achieved greater progress，if you had given her more chances. 如果你多给她点机会，她或许能取得更大的进步。,4“should/ought tohave done”表示“本来应该做某事，而实际没做”；“shouldnt/oughtnt tohave done”表示“本来不应该做某事，而实际做了”，二者都含有指责对方或自责的意味。 Tom，you are too lazy.The work should have been finished yesterday. 汤姆，你太懒惰了，这项工作本来应该昨天就做完的。 Look，Tom is crying.I shouldnt have been so harsh on him.看，汤姆哭了，我本来不应该对他如此严厉。,I ought to have gone home last Sunday. 我理应上星期日回家。 You ought not to have given him more help. 你不应该帮助他那么多。 5“neednthave done”表示“本来不需要做某事而做了”。 I neednt have bought so much wineonly five people were here. 我本来没有必要买这么多酒，只来了五个人。,.单项填空 1(2012北京高考)We the difficulty together，but why didnt you tell me? Ashould face Bmight face Ccould have faced Dmust have faced,【解析】 考查虚拟语气。句意：我们原本可以一起面对困难的，可是，你为什么不告诉我呢？由but和didnt可知，此处是与过去事实相反的虚拟语气，与过去事实相反的虚拟语气的主句形式为could/would/should/might have done，所以C项正确。A项和B项都是与现在事实相反的虚拟语气，可排除；D项表示推测，故排除。 【答案】 C,【解析】 题干的意思是：你的眼睛为什么这么红？你昨晚肯定没有睡好。是的，我熬夜写了一篇报告。cant have done意为“不可能做过”，表示对过去事情的否定推测。由题中的关键信息stayed up late writing a report“熬夜写报告”可推测昨晚没有睡好，所以选A。mustnt表示“禁止”，neednt表示“没必要”，wont表示“不愿意”，均不合题意。 【答案】 A,【解析】 句意：Harry(现在)感觉不舒服。昨天晚上在宴会上他肯定喝多了。此处表示对过去动作的肯定推测，应该用“情态动词havedone”结构，故排除A项和B项；C项不表示推测，而是虚拟语气，表示与过去的事实相反的情况；must have done意为“(过去)肯定做过某事”，表示对过去事情的肯定推测。 【答案】 D,4You all those clothes！We have a washing machine to do that sort of thing. Aneednt have washed Bshouldnt have washed Cmust not have washed Dcannot have washed 【解析】 句意：你不必洗衣服。我们有洗衣机做这样的事。neednt have washed“没有必要做某事，但实际上做了某事”。 【答案】 A,5Jenny have kept her word.I wonder why she changed her mind.

She to the hospital yesterday. Ahad to be taken Bshould have taken Cmust have been taken Dought to have been taken 【解析】 句意：我的小女儿咳嗽得很厉害了。昨天她就应该被送往医院。she与take to the hospital之间为被动关系，且表示“本来应该，但没有”，故选D。 【答案】 D,7Guess what！I have got A for my term paper. Great! You read widely and put a lot of work into it. Amust Bshould Cmust have Dshould have 【解析】 must have done表示“一定做了某事”，是对过去的肯定推测。根据语境可知答案为C。 【答案】 C,8I didnt go to work yesterday afternoon because my car broke down. You mine；I wasnt using it. Acould have borrowed Bmight borrow Cmust have borrowed Dought to borrow 【解析】 句意：昨天下午我没能去上班，因为我的车抛锚了。你本来可以借我的，那时我刚好不用它。表示对过去事情的虚拟，所以用could have done。 【答案】 A,9I wonder why Mr.Green looks worried today.
