3、固定句式:it is the first/second/last time that +延续性动词过去完成时 It is the first time that I have met Jane. 那是我第一次见到简。

第二节 被动语态 to do sth. 一般集中在挑错题中
特别关注:不定式的被动式,由主动变被动时to的特殊处理
相关知识:
A、及物动词和不及物动词 及物动词:后面可直接加宾语(名词、动名词、人称代词的宾格、数词)
不及物动词:后面不可直接加宾语,+介词+宾语 有些动词在不同的句子中既可作及物动词,也可作不及物动词。water 49. These part-time students expect to to offer some jobs on campus during the coming summer vacation. (0404A)
答:A,改为to be offed。
offer为及物动词,后面必须有宾语,若后面宾语,应是被动句
答:D。改为to be solved solve为及物动词 后面必须有宾语,若后面宾语,应是被动句 (2002)
答:B。改为;was cancelled (2002) 被动语态,因为cancel 是及物动词,而后面没有跟宾语,应考虑是被动语态。
B、行为动词与系动词 行为动词:表示实际动作,包括表示思维活动的词: want, think…等 系动词:表示主语的性质、状态和特征,be动词、可放在形容词前的某些动词:get、run、turn、smell…等
一、何种情况下可使用被动语态:
1,强调动作的接受者。
The kitchen is shared by the three of us. 厨房是我们三人用。
Football is played over of the world. 世界各地都踢足球。
2,不知道或没必要说明的执行者是谁。 The data have been computerized for two years now. 这些数据已经由计算处理两年了。 These books are written for children. 这些书是儿童读物
3,出于礼貌、措辞婉转等原因不方便、不愿意说明动作的执行者。
I was told that you are very lazy. 我听人说你很懒。 The car was damaged. 车撞坏了。
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.
It’s an honour for me to be invited to speak 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. The famous novel is said _ C. to have been translated _ into Chinese.
本句是动词不定式的完成、被动式。当不定式的逻辑主语是不定式表示的动作的对象时(或是动作的承受者时),不定式一般要用被动式。不定式的完成式所表示的动作发生在谓语动作或状态之前。如:He is not likely to have been told the result.这个结果可能还没有告诉他。 2000年
17. We shall ask for samples A and then we can make our decision. (0311)
A. to be sent B. being sent C. to set D. to have been sent
18. The forest fire caused by the volcano is difficult to be C . (0311)
A. put off B. put away C. put out D. put up
34. The question C at the meeting tomorrow is very important. (0411)
A. to discuss B. being discussed C. to be discussed D. will be discussed
2,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 write B. written C. writing D. write D。have sb do sth 让某人做某事。have此处为使役动词,后面接宾补的时候省to
58. The middle-aged man was seen _____ out of the house on the afternoon of the murder.
A. came B. come C. to come D. have come
C。感官动词feel,hear,see,watch等后面接宾补的时候,要用无to不定式。但如果句子是主语的补足语的话,要加上to。 (2000)
3,短语动词的被动语态。动词后面接一个介词或副词构成短语,将其看成一个及物动词。
The children are 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 was asked where to find the manager.
6,特殊句型 be said/reported to have done 据说/据报道
22. The famous novel is said _____ into Chinese.
A. to have translated B. to be translate C. to have been translated D. to translate
答C。本句是动词不定式的完成、被动式。当不定式的逻辑主语是不定式表示的动作的对象时(或是动作的承受者时),不定式一般要用被动式。不定式的完成式所表示的动作发生在谓语动作或状态之前。如:He is 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. I'm going to get the film _____.
A. being developed B. developing C. developed D. to be developed 答:C。过去分词在动词have, get两词后面作宾补时,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 had B. could have had C. should have had D. must have had
47. Something must have happened on their way here. Or they _________by now. (02)
A. should have arrived B. should arrive C. would have arrived D. 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 rain
may + have done 对过去发生的事情的较有把握的猜测,“也许“
22. I can’t 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、I’m sorry I couldn’t get in touch with him before he left, I ____ him earlier. (2000)
A. had a telephone B. have phoned C. should have phoned D. should be phoned
36、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 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 didn’t get our invitation 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4-5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 should + 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. know
B. 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. came
C. 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
⑴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,即把这些词放到主语前面。
1. _____ you were busy, I wouldn't have bothered you with my questions. (B, 96年)
A. If I realized B. Had I realized C. Did I have realized that D. As I realized
57. Had the weather been good, the children _____ out for a walk. (2001)
A. had gone B. could have gone C. would go D. went
答:B。当虚拟语气中含有were, 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 have 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
⑵ 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 couldn’t 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 finished
32. 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
