19、。4，避免变换主语，以求行文流畅。 He appeared on the stage and was warmly applaused by the audience. 他出现在舞台上时，观众的热烈鼓掌。二、使用被动高不成低不就需要注意的问题1，不定式的被动式 to be done 当不定式的逻辑主语是这个不定式表示的动作的接受者, 用被动式He asked to be sent to work in Tibet. 他要求派去西藏工作I want to do some shopping tomorrow. Its an honour for me to be invited to speak
20、here today. 很荣幸被邀请Are you going to the meeting to be held at 6:00? 你要参加6点的会吗？22.

22、mportant. (0411)A. to discuss B. being discussed C. to be discussed D. will be discussed2，某些动词由主动变被动时不定式符号”to”的处理 7个感观动词see, watch, observe, notice, listen to, hear,fell; 3个使役动词let, have让, make 56. The teacher has his students _ a composition every other week. (2000) A. to writeB. writtenC. writingD

24、e well looked after. 这些孩子得到了很好的照顾。(介)The meeting has been put off till next week. 会议被推迟到下周。(副)注意：不是所有短的语动词都有被动语态，判断：相连的介词或副词不能折开4，带情态动词的被动语态：情态动词+be+过去分词。 Bad things sometimes can be turned into good ones. 坏事有时可变好事5，被动语态后可接从句或W不定式He was told that his father was sick. 他被告知他父亲病了A assistant of the shop

26、s not likely to have been told the result.这个结果可能还没有告诉他。 (2000)7，get + 动词过去分词构成被动语态， 多用于口语或非正式书面语中 He had some pictures taken in the park. 他在公园里照了几张像。(别人给他照的48. I have taken many photos. Im going to get the film _.A. being developedB. developingC. developedD. to be developed 答：C。过去分词在动词have, get两词后面作
27、宾补时,常常表示这个动作不是由主语完成的,而是由别人完成的。 (2001)第三节 情态动词情态动词用来表示能力、允许、许诺、可能、劝告、意愿等概念或态度,无人称变化,在句子中和动词原形一起构成谓语。着重测验情态动词接完成时的用法。一、must + have done 表示对过去发生的事情的有把握的猜测。58、I believe he _ an accident, otherwise he would have arrived on time. (D,01)A. would have hadB. could have had C. should have hadD. must have had4
28、7. Something must have happened on their way here. Or they _by now. (02)A. should have arrivedB. should arriveC. would have arrivedD. would arrive 答：C。第一句是must+have +过去分词的结构，表示对过去事实的推测。The road is wet. It must have rained last night.路是湿的，昨晚上肯定下雨了。因此我们可以推断：这是一个和过去的事实相反的虚拟语气。should +have +过去分词的结构，表示对过
29、去动作的责备、批评。如：You should have gone over your lessons.你应当把功课复习好的。但是此句只是一个表示和过去的事实相反的虚拟句子，并没有责备的意思。本句意思：路上肯定出事了,否则他们现在已经到了。因此正确答案应是C.35. Since this road is wet and slippery this morning, it last night. (C,0411)A. must rain B. was raining C. must have rained D. may rainmay + have done 对过去发生的事情的较有把握的猜测，“也
30、许“22. I cant find the recorder in the room. It C may have been taken by somebody. ( 0311) 二、should (ought to) + have done 含有对过去的动作的责备、批评意思 肯定表示应该做的事情而没有做26、Im sorry I couldnt get in touch with him before he left, I _ him earlier. (2000)A. had a telephone B. have phoned C. should have phoned D. shoul
31、d be phoned36、You ought to B to have reported the matter to the manager the day before yesterday. 否定式表示不该做的事情做了 They should not have left so soon. 他们不应该这么早就走的 She was very unhappy. You ought not to have hurt her feeling. 她当时够难受了你不应该再伤害她三、would (not) have done 表示过去没有完成的动作，多和虚拟语气连用，不含批评意思45. Mary said
32、 to me, “Had I seen your bag, I it to you.” (D,0404)A. will return B. must return C. could return D. would have returned四、could + have done 表示过去存在的某种可能性，但这种可能性由于客观条件限制没能实现。表示对过去能做而未做的事情感到惋惜，遗憾。You could have made a more detailed plan. 你本可以做出更详尽的计划。 He could have joined us, but he didnt get our invit
33、ation in time.他本来能够参加我们的，但是他没有收到我们的请贴。第四节 虚拟语气 (每次考试一般占45分)所表示的条件根本不可能实现或实现的可能性很小，称为虚拟条件句。虚拟条件句，主句与从句中谓语动词的形式可分为下面三类：假设类型 条件从句动词的时态 结果主句的动词的时态与现在事实相反 if + 过去式(be只用were不用was) would/should/might/could + 动词原型与过去事实相反 if had + 去过分词 would/should/might/could + have + 过去分词与将来事实可能相反 if were to + 动词原形if shoul
34、d + 动词原形 would/should/might/could + 动词原型一、在条件句中的应用： If he had time, he would come. 如果有时间，他一定来。(已经过去)A. 现在事实 I would certainly go if I had time. 如果我有时间当然去。 If he were here, he might help you. 如果他在这也许帮能你。1、I would ask George to lend us the money if I _ him. (C, 95年)A. had known B. have known C. knew D
35、. knowB. 过去事实 59、If Bob_ with us, he would have had a good time. (C, 95年)A. would come B. would have come C. had come D. cameC. 将来事实 we would state at home if it should rain tomorrow. If I were to do the examination I would it some other way.注意条件从句中，如果含有be动词、助动词、情态动词, had, should或动词to have，可省略if，要倒装
36、，即把这些词放到主语前面。1. _ you were busy, I wouldnt have bothered you with my questions. (B, 96年)A. If I realizedB. Had I realizedC. Did I have realized thatD. As I realized57. Had the weather been good, the children _ out for a walk. (2001)A. had gone B. could have goneC. would go D. went 答：B。当虚拟语气中含有were,
37、had, should, would等词时， 可以省略if, 把这些词放在主语之前。Should I meet her, I would tell her.万一我见到他， 我会告诉他的。Were I in your position, I would do it better.如果我处在你的位置上， 我会做的更好。Had they made preparations, they would have succeeded.如果他们准备了的话， 他们应该能成功的。本句为和过去的事实相反的虚拟语气，因此选B。32. the advice of his friends, he would not ha
38、ve suffered such a heavy loss in his business. (D, 0404) A. If he took B. If he should take C. Were he to take D. Had he taken 条件从句有时可以用介词短语代替。有时一个假设的情况不用条件从句表示，而用其它方式来表示，这样的句子叫含蓄条件句。常用with，without，but for。We couldnt have achieved so much without your help. 要不是你们帮忙我们不会取得这么大的成绩36. But for my classmat
39、es help, I the work in time. (D, 0404)A. did not finish B. could not finish C. will not finish D. would not have finished32. Without heat and sunlight, plants on the earth well. (A, 0411)A. would not grow B. will not grow C. had not grown D. would not be grown 条件从句有时可以用介词短语代替。有时一个假设的情况不用条件从句表示，而用其它方
40、式来表示，这样的句子叫含蓄条件句。常用with，without，but for。We couldnt have achieved so much without your help. 要不是你们帮忙我们不会取得这么大的成绩36. But for my classmates help, I the work in time. (D, 0404)A. did not finish B. could not finish C. will not finish D. would not have finished32. Without heat and sunlight, plants on the
41、earth well. (A, 0411)A. would not grow B. will not grow C. had not grown D. would not be grown二、以wish（that）引导的表示“愿望”的宾语从句，虚拟语气中时态类似在非真实条件从句中时态的应用时态后移, 引导从句的that可以省略表示现在或将来的愿望相反的用过去时：主语wish 从句(过去时) were I wish (that) I were as young as you. 我真希望和你们一样年青 I wish (that) I knew his address. 我真希望知道他的地址与将来的愿望相反即愿望难以实现（用过去将来时），I wish I could be of more use in the future.我希望我将来有点用处。表示与过去没有实现的愿望用过去完成时： 主语wish +从句（主语过去完成时） I wished he hadnt made the big mistake.他要是不犯那个大错误，该有多好！32.
