1、语法专题(九)省略与倒装,省 略 一、简单句中的省略 一个句子中有时一个或更多的成分被省略，这样的句子称为省略句。省略主要出现在下列情况中： 1省略主语 (It)Sounds like a good idea. (这个)听起来是个好主意。 (I)Beg your pardon？请(你)再说一遍？,这样考过 Hi，Sam，Im going to take a long walk along the sunny beach and go swimming today. _ ! AHow nice you are BThats all right CSounds great DGood exerci

2、se,解析：考查交际用语。这道题实际上是将主谓一致和交际用语结合起来进行考查。当对方提出建议，你认为是个好主意的时候，可以说Thats a good idea./That sounds great./That sounds good.在口语中，我们常常把主语省略，但如果省略的主语是第三人称单数，其动词仍然需要加上s。 答案：C,2省略谓语或谓语的一部分 (Does)Anybody need help？谁需要帮忙？ (Is there)Anything to drink？有喝的吗？,这样考过 Be careful！Dont forget you are on a ladder. But you

3、are holding it for me，nothing _. Aworry about Bto worry about Cis worried about Dworrying about 答案：B, Mum，you always tell me that if I work hard，I will pass the exam.

4、ther he is or not.) 对不起，我不知道(他是否在)。,这样考过 Jim managed to get into his house without the key._？ I dont know.He might have asked someone for help. AWhat for BGuess how CSo what DWho knows,解析：句意：“吉姆没有钥匙却设法进了房子。猜猜怎么进去的？”“不知道。他可能向别人求助了吧。”what for“为何”；so what“那又怎么样”；who knows“谁知道”。题干中的问句补充完整为：Guess how he

5、got into the house without the key. 答案：B,4省略主语和谓语(或谓语的一部分) (It is a)Pity that we live so far from the sea. 真遗憾，我们住得离海太远了。,这样考过 Have you finished your first paper? _.Just half of it.How about you? ANot at all BNot likely CNot a bit DNot yet 解析：句意：你的第一篇论文写完了吗？还没有。刚完成一半。你呢？首先排除A、C，因为not at allnot a bit

6、一点也不，不符合题意；not likelyused to disagree strongly with a statement or suggestion绝不可能，绝对不会，也不符合题意。 答案：D, Why didnt you buy the book? I _，but I didnt have enough money with me. Awould Bhad had Cwould have Dhad bought 解析：根据句意可知，我本来会买的，可是当时我没有钱，所以没买。表示与过去事实相反，主句的谓语用would have done。 答案：C, Who are you waitin

7、g for? _ the man wounded in the left leg. AThe doctor will operate on BThe nurse to be looked after CThe doctor to operate on DHis brother got,解析：回答的who是作wait for的宾语，而A、D两项是句子的表达形式，所以排除；B项应该把to be looked after改为to look after。答语中to operate on the man作定语，修饰the doctor；wounded in the left leg过去分词短语作定语修饰

8、the man。所以只有C项正确。该句补充完整为：I am waiting for the doctor to operate on the man wounded in the left leg. 答案：C, Excuse me.Can you help me to change this 20 note for coins，please? Oh，sure！_？ AWhat for BFor what CHow much DHow many 解析：What for补充完整为：What do you change it for？Why do you change it？句意：“对不起，你能帮我

9、把这20英镑兑换成硬币吗？”“哦，没问题。但是你为什么兑换呢？” 答案：A,二、并列句中的省略 1在并列句中，省略是常见的语法现象。在不引起歧义的情况下，后句与前句相同的部分可以省略。 Disney picked up his pencil and(he)started to draw. 迪斯尼拿起铅笔，(他)开始画了起来。 His suggestions made John happy，but(his suggestions made)Mary angry. 他的提议使约翰很高兴，但(他的提议使)玛丽很生气。,这样考过 Does Betty know where her violin is?

10、 She saw somebody walking off with one，but she doesnt know _. Awhose Bit Cwhom Dwhich 解析：设空句是省略句，完整的句子应该是“.but she doesnt know _ violin it is.”引导词在宾语从句中作定语，意思是“谁的”，应用whose。 答案：A,2省略主语 He talked little but(he)did much.他说的少做的多。 I am and will always be at your service. 不管现在和将来，我随时为你效劳。 3省略谓语或者谓语主要部分 Jo

11、lley will be arriving today and Ann tomorrow. 乔利今天到，安明天到。 He works in a factory，and his brother on a farm. 他在工厂工作，他兄弟在农场工作。 John will sing at the party and Mary wont. 约翰将在宴会上唱歌，玛丽不唱。,这样考过 As is known to all，Montreal is the second largest Frenchspeaking city in the world，_. AParis is the largest BPar

12、is to be the largest CParis the largest DParis be the largest,解析：若两个句子之间有逗号隔开，那么这两个句子之间必须要有连词，若无连词，则要改为非谓语的形式。此题若选A项，缺少连词；B、D两项的非谓语表达形式与此题不符。所以此题只有C选项的省略形式是正确的。 答案：C,4省略宾语或表语 John likes smoking，but Mary hates. 约翰喜欢吸烟，但玛丽讨厌。 Bob hasnt written his report，but he will soon. 鲍勃还没写报告，但他很快就写。 此外，下面这种类型的句子也

Ahopes to Bhopes so Chopes not Dhopes for 解析：句意：Della怎么了？哦，她父母不让她去参加晚会，但她仍然希望去参加。本句属省略句，完整形式应为：.，but she still hopes to go to the party. 答案：A, Will you go

15、 home tomorrow evening? No，I am going to a lecture，or at least I am planning_. Aso Bto Cit Dthat 解析：用不定式符号to代替整个不定式to go to a lecture。 答案：B,2有时形容词或名词后的整个动词不定式可以省略 Id like to come，but I have no time(to) 我想来，但我没有时间来。 Hell never leave home；he hasnt got the courage(to) 他永远不会离开家，他也没有勇气离开家。,3在助动词have to，o

17、um instead of walking? No，thanks，_. AIm able to BIm used to CIm about to DIve got to 解析：句意：你为什么不坐我的车去博物馆而是步行呢？不用了，谢谢，我习惯了。be able to“能够”；be used to“习惯于”；be about to“正打算，正要”；have got to“不得不”。故选B项。 答案：B,4want和(would)like后的不定式在省略后常要保留to，但在从句中却常常一起省略 Come when you want.想来你就来。 Come and stay as long as yo

18、u like. 你来吧，想住多久就住多久。,5在see，watch，hear，feel，observe，notice，look at，listen to等感官动词或使役动词make，let，have等之后的“宾语不定式作宾补”结构中，不定式不带to。但这类动词如为被动语态，to须保留。在why not.(为什么不)句型中，to常省去 I often hear her sing the folk song. 我常听到她唱这首民歌。 The boss made the workers work day and night. 老板迫使工人们日夜干活。,He was seen to enter the

19、 room. 有人看见他走进房间去了。 Jim was observed to go home. 有人看见吉姆回家了。 Why not try again？为什么不再试一下？,可能这样考 The boy watched the cooks_with each other for an hour. Afight Bfights Cto fight Dfighted 解析：watch后面可接不定式或动名词作宾语补足语，其形式为watch sb.do/doing sth.，但强调看到某人做某事的全过程，则用watch sb.do sth.，故正确答案为A。 答案：A,6在介词but/except等前

20、边有实义动词do的某种形式时，其后的to可以省去 He can do nothing but/except lie down and sleep. 他别无选择，只好躺下睡觉。 There is nothing to do but wait.只好等待。,可能这样考 And then there was no choice but_down and sleep.

23、句主语为it，谓语动词是be，常常可以省略从句的主语和谓语动词(或助动词)be,这样考过 Who should be responsible for the accident? The boss，not the workers.They just carried out the order _. Aas told Bas are told Cas telling Das they told,解析：句意：谁应当对这一起事故负责？是老板，而不是工人。工人们只是执行了他们被吩咐的指令。从题意可知，workers和tell之间应当是被动关系，排除C、D。而当从句主语和主句主语一致，且从句中有be动词时

24、，从句主语和be动词可以同时省去。A项可以补全为：They just carried out the order as they were told。 答案：A,The flowers his friend gave him will die unless _ every day.

26、 commonly _. Asupposing Bto suppose Cbeing supposed Dsupposed 解析：考查非谓语动词的用法。suppose与其逻辑主语it是动宾关系，所以用过去分词形式表被动。 答案：D,3其他情况 She did all she could(do)to help him. 她竭尽全力地帮助他。 Well get everything ready tomorrow if not earlier(If we cant get it ready earlier)我们最迟明天把一切准备好。,可能这样考 Have you been to the Great

49、妈直到我回家才上床睡觉。not until引导状语从句且提前置于句首需要部分倒装，又因为时态是过去时(从came可知)，所以要将助动词did提前。 答案：B,Little _ that we were watching his every move，so he seemed to be going his own way in this business.
