Then came the chairman. Here is your letter. 2) 表示运动方向的副词或地点状语置于句首，谓语表示运动的动词。 Out rushed a missile from under the bomber. Ahead sat an old woman. 注意：上述全部倒装的句型结构的主语必须是名词，如果主语是人称代词则不能完全倒装。 Here he comes. Away they went. 2 倒装句之部分倒装 部分倒装是指将谓语的一部分如助动词或情态倒装至主语之前。如果句中的谓语没有助动词或情态动词，则需添加助动词do, does或did，并将其置于主语之前。 1) 句首为否定或半否定的词语，如no, not, never, seldom, little, hardly, at no time, in no way, not until… 等。 Never have I seen such a performance. Nowhere will you find the answer to this question. Not until the child fell asleep did the mother leave the room. 当Not until引出主从复合句，主句倒装，从句不倒装。 注意： 如否定词不在句首不倒装。 I have never seen such a performance. The mother didn't leave the room until the child fell asleep. 典型例题 1) Why can't I smoke here? At no time___ in the meeting-room A. is smoking permitted B. smoking is permitted C. smoking is it permitted D. does smoking permit 答案A. 这是一个倒装问题。当否定词语置于句首以表示强调时，其句中的主谓须用倒装结构。 这

魏秋蓉 授课老师 授课形式 苏亮亮 一对一 （ ） 小组授课（ ） 所授科目 课 时 数 授课课时 英语 总（ ）课时 第（ ）课时 （ ）课时 倒装和虚拟语气 掌握倒装句和虚拟语气的具体用法 些否定词包括no, little, hardly, seldom, never, not only, not until等。本题的正常语序是 Smoking is permitted in the meeting-room at no time. 2） Not until the early years of the 19th century ___ what heat is. A. man did know B. man know C. didn't man know D. did man know 答案D. 看到Not until…的句型，我们知道为一倒装句，答案在C，D 中选一个。 改写为正常语序为，Man did not know what heat is until the early years of the 19th. 现在将not提前，后面就不能再用否定了,否则意思就变了。 3 以否定词开头作部分倒装 如 Not only…but also, Hardly/Scarcely…when, No sooner… than Not only did he refuse the gift, he also severely criticized the sender. Hardly had she gone out when a student came to visit her. No sooner had she gone out than a student came to visit her. 典型例题 No sooner___ than it began to rain heavily. A. the game began B. has the game begun C. did the game begin D. had the game begun 答案D. 以具有否定意义的副词放在句首时，一般采用倒装句(谓语前置)。这类表示否定意义的词有never, seldom, scarcely, little, few, not, hardly, 以及not only…but (also), no sooner…than, hardly… when scarcely… when 等等。 注意：只有当Not only… but also连接两个分句时，才在第一个分句用倒装结构。如果置于句首的Not only… but also仅连接两个并列词语，不可用倒装结构。 Not only you but also I am fond of music 4 so, neither, nor作部分倒装 表示\"也\"、\"也不\" 的句子要部分倒装。 Tom can speak French. So can Jack. If you won't go, neither will I. 典型例题 ---Do you know Jim quarrelled with his brother? ---I don't know, _____. A. nor don't I care B. nor do I care C. I don't care neither D. I don't care also 答案：B. nor为增补意思\"也不关心\"，因此句子应倒装。A错在用 don't 再次否定， C neither 用法不对且缺乏连词。 D缺乏连词。 注意： 当so引出的句子用以对上文内容加以证实或肯定时，不可用倒装结构。意为\"的确如此\"。 Tom asked me to go to play football and so I did. ---It's raining hard. ---So it is. 5 only在句首要倒装的情况 Only in this way, can you learn English well. Only after being asked three times did he come to the meeting. 如果句子为主从复合句，则主句倒装，从句不倒装 Only when he is seriously ill, does he ever stay in bed. 6 as, though 引导的倒装句 as / though引导的让步从句必须将表语或状语提前 （形容词, 副词, 分词, 实义动词提前）。 1) 句首名词不能带任何冠词。 2) 句首是实义动词, 其他助动词放在主语后。如果实义动词有宾语和状语, 随实义动词一起放在主语之前。

Try hard as he will, he never seems able to do the work satisfactorily. 让步状语从句中，有though，although时，后面的主句不能有but，但是 though 和yet可连用 虚拟语气 1） 概念 虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。 2） 在条件句中的应用 条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。 1 真是条件句 真实条件句用于陈述语气，假设的情况可能发生，其中 if 是如果的意思。 时态关系 句型： 条件从句 主句 一般现在时 shall/will + 动词原形 If he comes, he will bring his violin. 典型例题 The volleyball match will be put off if it ___. A. will rain B. rains C. rained D. is rained 答案B。真实条件句主句为将来时，从句用一般现在时。 注意： 1） 在真实条件句中，主句不能用be going to表示将来，该用shall, will. (错) If you leave now, you are never going to regret it. (对) If you leave now, you will never regret it. 2） 表示真理时，主句谓语动词便不用shall (will) +动词原形，而直接用一般现在时的动词形式。 2 非真是条件句 1）时态：可以表示过去，现在和将来的情况。它的基本特点是时态退后。 a. 同现在事实相反的假设。 句型 ： 条件从句 主句 一般过去时 should( would) +动词原形 If they were here, they would help you. b. 表示于过去事实相反的假设。 句型： 条件从句 主句 过去完成时 should(would) have+ 过去分词 If she had worked harder, she would have succeeded. The rice would not have been burnt if you had been more careful. If my lawyer had been here last Saturday, he would have prevented me from going. If he had come yesterday, I should / would have told him about it. 含义：He did not come yesterday, so I did not tell him about it. If he had not been ill and missed many classes, he would have made greater progress. 含义： He was ill and missed many lessons, so he did not make greater progress. c. 表示对将来的假想 句型： 条件从句 主句 一般过去时 should+ 动词原形 were+ 不定式 would + 动词原形 should+ 动词原形 If you succeeded, everything would be all right.

If you should succeed, everything would be all right. If you were to succeed, everything would be all right. 3混合条件句 主句与从句的动作发生在不同的时间，这时主，从句谓语动词的虚拟语气形式因时间不同而不同，这叫做混合条件句。 If you had asked him yesterday, you would know what to do now. （从句与过去事实相反，主句与现在事实相反。） If it had rained last night (过去), it would be very cold today (现在). 4 虚拟条件句的倒装 虚拟条件句的从句部分如果含有were, should, 或had, 可将if省略，再把were, should或had 移到从句句首，实行倒装。 Were they here now, they could help us. =If they were here now, they could help us. Had you come earlier, you would have met him =If you had come earlier, you would have met him. Should it rain, the crops would be saved. =Were it to rain, the crops would be saved. 注意： 在虚拟语气的从句中，动词'be'的过去时态一律用\"were\"，不用was， 即在从句中be用were代替。 If I were you, I would go to look for him. 如果我是你，就会去找他。 If he were here, everything would be all right. 如果他在这儿，一切都会好的。 典型例题 _____ to do the work, I should do it some other day. A. If were I B. I were C. Were I D. Was I 答案C. 在虚拟条件状语中如果有were, should, had这三个词，通常将if省略，主语提前, 变成 were, should, had +主语的形式。但要注意，在虚拟条件状语从句中，省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说 Were I not to do., 而不能说 Weren't I to do. 5 wish的用法 1）用于wish后面的从句，表示与事实相反的情况，或表示将来不太可能实现的愿望。其宾语从句的动词形式为： 真实状况 wish后 从句动作先于主句动词动作 现在时 过去时 （be的过去式为 were） 从句动作与主句动作同时发生 过去时 过去完成时 （had + 过去分词） 将来不大可能实现的愿望 将来时 would/could + 动词原形 I wish I were as tall as you. 我希望和你一样高。 He wished he hadn't said that. 他希望他没讲那样的话。 I wish it would rain tomorrow. 我希望明天下雨就好了。 2）Wish to do表达法。 Wish sb / sth to do I wish to see the manager. = I want to see the manager. I wish the manager to be informed at once. (= I want the manager to be informed at once.)

6比较if only与only if only if表示\"只有\"；if only则表示\"如果……就好了\"。If only也可用于陈述语气。 I wake up only if the alarm clock rings. 只有闹钟响了，我才会醒。 If only the alarm clock had rung. 当时闹钟响了，就好了。 If only he comes early. 但愿他早点回来。 7 It is (high) time that It is (high) time that 后面的从句谓语动词要用过去式或用should加动词原形，但should不可省略。 It is time that the children went to bed. It is high time that the children should go to bed. 8 need \"不必做\"和\"本不该做\" didn't need to do表示： 过去不必做某事, 事实上也没做。. needn't have done表示： 过去不必做某事, 但事实上做了。 John went to the station with the car to meet Mary, so she didn't need to walk back home. 约翰开车去车站接玛丽，所以她不必步行回家了。 John went to the station with the car to meet Mary, so she needn't have walked back home. 约翰开车去车站接玛丽，所以她本不必步行回家了。 (Mary步行回家，没有遇上John的车。) 典型例题 There was plenty of time. She ___. A. mustn't have hurried B. couldn't have hurried C. must not hurry D. needn't have hurried 答案D。needn't have done. 意为\"本不必\"，即已经做了某事，而时实际上不必要。 Mustn't have done 用法不正确，对过去发生的事情进行否定性推断应为couldn't have done, \"不可能已经\"。 must not do 不可以（用于一般现在时）。 请在下列选项中打√ 学生评价 1. 讲课生动易懂 □ 一般 □ 枯燥乏味 □ 学生签名 2. 收获很大□ 有点收获□ 不知道学到了什么□ 教学反思 审核签名
