8、t (5). You cant imagine _when they received the nice gift.A. how they were excited B. how excited they were C. how excited were they D. they were how excitedl 在以下情况中that不能省略1、当句中的动词后接多于两个由that引导的宾语从句时，第一个that可省，但后面的that不可省。I believe(that)you have done your best and that things will get better.2、当主句的

9、谓语动词与that宾语从句之间有插入语时，that一般不可省。Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap. 3、当that从句是双宾语中的直接宾语时，that不可省。I cant tell him that his mother died. 4、当it作形式宾语时 例句：She made it clear that she had nothing to do with him许多带复合宾语的句子，that引导的宾语从

10、句经常移到句子后部，而用it作形式宾语。5、当宾语从句前置时 That our team will win，I believe6、当that作learn,suggest,explain,agree,wonder,prove,mean,state,feel,hold等动词的宾语时; 2、由whether,if 引导的宾语从句当由一般疑问句充当宾语从句时，用if或whether引导，意为“是否”。如：I dont know if /whether he still lives here after so many years我不知道这么多年后他是否还住在这儿。l 但在下列情况下只能用whether

11、，不能用if：在具有选择意义，又有or或or not时，尤其是直接与or not连用时，往往用whether(ifor not也可以使用)。如：Let me know whether /if he will come or not(Let me know whether or not he will come)让我知道他是否能来。I dont know whether /if he does any washing or not(I dont know whether or not he does any washing)我不知道他洗不洗衣服。I wonder whether we stay

12、or whether wego我不知道我们是去还是留。在介词之后用whether。如：Im interested in whether he likes English我关心的是他是否喜欢英语。Were thinking about whether we can finish the work on time.我们正在考虑是否能按时完成这项工作。在不定式前用whether。如：He hasnt decided whether to visit the old man他尚未决定是否拜访那位老人。He hasnt decided whether to go by bus or by train他还

13、未决定是乘公共汽车去还是坐火车去。whether置于句首时，不能换用if。如：Whether this is true or not，I cant say这是否真的我说不上来。引导主语从句和表语从句时宜用whether。如：Whether she will come or not is still a question她是否能来还是个问题。若用if会引起歧义时，则用whether。如：Please let me know if you like the book可理解为：If you like the book，please let me know你如果喜欢这本书，请告诉我l 只能用if不能用

14、whether引导的宾语从句if引导条件状语从句，意为“如果”The students will go on a picnic if it is sunny.if引导否定概念的宾语从句时He asked if I didnt come to school yesterday. 引导状语从句even if(即使)和as if(好象)时He talks as if he has known all about it. 二)、连接代词和连接副词引导的宾语从句这样的宾语从句实际上是由特殊疑问句变化而来的，宾语从句要用陈述句语序。用于这种结构的动词常常是：see, say, tell, ask, ans

20、从句的语序无论主句是陈述句还是疑问句，宾语从句都必须使用陈述语序，即“主句连词宾语从句(主语谓语)”句式。根据连接词在从句中所担任的不同成分，可分为以下四种：1)连接词谓语。连接词在从句中作主语。常见的连接词有：who，what，which等。如：Could you tell me who knows the answer，please？你能告诉我谁知道答案吗？The small children dont know what is in their stockings这些小孩子不知道袜子里有什么东西？2)连接词名词谓语。连接词在从句中作主语的定语。常见的连接词有：whose，what，whi

21、ch，howmany，how much等。如：He asked whose handwriting was the best in our class他问我们班上谁的书法最好。The teacher asked us how many people there were in the room老师问我们房间里有多少人。3)连接词主语谓语。连接词在从句中作宾语、状语或表语。常见的连接词有：who(m)，what，which，how many，how much， when，why，how，where，if whether(在句中不充当任何成分)等。如：He hasnt decided if hel

26、l 主句是过去时态，从句须用过去时态的某种形式。例句：She was sorry that she hadnt finished her work on time. l 当宾语从句表示的是一个客观真理或者事实时，即使主句是过去时，从句也用一般现在时态。例句：The teacher told his class that light travels faster than sound. 练习题：(1) Its 7:30. I cant believe you_ cooking dinner yet, Sally.A. havent started B. didnt C. dont start D

27、. hadnt started(2) The teacher told us yesterday that December 25 _ Christmas Day.A. is B. was C. has been D. will be (3) The teacher said that the earth _round the sun.A. goes B. go C. went D. will go(4) We d like to tell you that you _the exam.A. have passed B. had passed C. pass D. will pass (5)

29、r that he _ to Beijing yesterday.A. goes B. will go C. went D. have gone注意：l 运用虚拟语气的情况在表示：建议 suggest 、advise、propose；要求demand 、desire、request； 决定 decide；命令 order、command、require；坚决主张 insist；等动词后跟宾语从句，用(should)+v(虚拟语气) Eg：I suggested that you(should)study hard.He ordered that we should go out at once

30、.l 虚拟语气的用法虚拟语气是一种动词形式，表示说话人的一种愿望，假设，怀疑，猜测，建议等含义，虚拟语气所表示的含义不是客观存在的事实。虚拟语气的用法：1) 虚拟语气用在简单句中，表示祝愿，命令。如：May you be happy. 祝你幸福。May you have a good time. 祝愿你玩得痛快。May the friendship between us last long. 祝愿我们的友情天长地久。Have a good journey! 祝愿你旅途愉快！You go out！ 你出去！2) 虚拟语气用在宾语从句中：动词 wish, suggest,order,insist,

31、 propose,等词后面的宾语从句表示的是一种虚拟语气，宾语从句中的动词动作表示的只是一种愿望、要求。如：I wish she would be on my side. 我希望她能站在我一边。I wish I could help him. 我希望我能帮助他。He insisted that all of us should be there on time by any means.他坚持要我们大家想尽办法按时去那儿。动词 demand, suggest, order, insist, propose 后面的从句中，should 可以省略。如：The teacher suggested t

32、hat we (should) clean the blackboard after class.老师建议我们课后把黑板擦了。He ordered that the students wash the clothes every week by themselves.他要求学生每周都要自己洗衣服。3) 虚拟语气用在主语从句中：在句型 It is important (necessary, strange, natural) that . 中，that 后面的从句中的谓语动词用： should + 动词原形，如：Its necessary that we should have a walk n

33、ow. 我们有必要出去散散步。Its natural that she should do so. 她这样做是很自然的。Its important that we should take good care of the patient. 重要的是我们要照顾好病人。4) 虚拟语气用在状语从句中：虚拟语气最多地用在表示条件的状语从句和表示结果的从句中。在表示与事实相反的虚拟语气时，动词有三种时态形式，即现在、过去和将来。 A、与现在事实相反的：If I (we,you,he,they)+ 动词过去式. if I (he,she) were. I (we) should + 动词原形。 He (y

34、ou,they) would + 动词原形。 B、与过去事实相反的：If I(we,you,he,they)+ had + 过去分词 I(we)should + have+ 过去分词。He (you,they) would + have + 过去分词。 If I were you, I should buy it. 如果我是你，我就买了它。 If I had time, I would study French. 如果我有时间，我会学习法语的。 If she knew English,she would not ask me for help. 如果她懂英语的话，她不会找我帮忙的。 If yo

35、u had got up earlier, you could have caught the train. 如果你早一点起床，就会赶上火车的。 If it were fine tomorrow,I would go shopping. 如果明天天气好，我就去买东西。明白了虚拟语气的用法就会明白什么时候需要用虚拟语气了，在表示说话人的一种愿望，假设，怀疑，猜测，建议等含义，或表示的含义不是客观存在的事实时需要用虚拟语气。l 简化宾语从句常用六法同学们常会遇到把含有宾语从句的复合句转化为简单句，使其与原句意思相同(或相近)的试题。下面就介绍几种常用的简化宾语从句的方法：方法一：当主句谓语动词是h

36、ope，decide，wish，choose，agree，promise等，且宾语从句的主语与主句主语一致时，宾语从句可简化为不定式结构。例如：Li Ming hopes he will be back very soon. Li Ming hopes to be back very soon.We decided that we would help him. We decided to help him.方法二：当主句谓语动词是know， learn， remember， forget， tell等动词，且主句主语与从句主语一致时，宾语从句可简化为“疑问词+不定式”结构。例如：She ha

37、s forgotten how she can open the window. She has forgotten how to open the window.注：当主句谓语动词是tell, ask, show, teach等动词，且后带双宾语，从句主语和间接宾语一致时，宾语从句可简化为“疑问词+不定式”结构。例如：Could you tell me how I can get to the station？ Could you tell me how to get to the station？方法三：当主句的谓语动词是order(命令)，require(需要)等时，如果主句和从句的主语

38、不一致，宾语从句可简化为“名词(代词)+不定式”结构。例如：The headmaster ordered that we should start at once. The headmaster ordered us to start at once.方法四：某些动词后的宾语从句，可以用介词加动名词(短语)等其他形式简化。例如：He insisted that he should go with us. He insisted on going with us.The poor boy doesnt know when and where he was born. The poor boy d

39、oesnt know the time and the place of his birth.方法五：某些动词后面的宾语从句可转化为“宾语+V-ing形式(作宾语补足语)”结构。例如：Liu Ping found that there was a wallet lying on the ground. Liu Ping found a wallet lying on the ground.方法六：动词seem后的宾语从句，也可以用不定式(短语)来简化，但句型需要进行适当的变化。例如：It seemed that the boys were going to win. The boys seem

40、ed to win.除上述方法外，还有一些特殊句式的转化。例如：I found that it was difficult to learn English well. I found it difficult to learn English well.Soon we found that the ground was covered with thick snow.
