名詞性從句難點及考點歸納

1、名詞性從句難點及考點歸納名詞性從句包括主語從句、賓語從句、表語從句、同位語從句。其重點、難點及高考熱點是語序、引導(dǎo)詞選用和時態(tài)呼應(yīng)等問題。 現(xiàn)綜述如下（選項為斜體的是正確答案)： 一、語序 名詞性從句的引導(dǎo)詞都位于從句之首，從句均為陳述語序（主謂不倒裝)。 As soon as he comes back, Ill tell him when _ and see him. A. you will come B. will you come C. you come D. do you come He asked _ for the violin. A. did I pay how much B.

2、 I paid how much C. how much did I pay D. how much I paid 二、引導(dǎo)詞的選用 1. whether與if (1）引導(dǎo)主語從句（放在句首)、表語從句、同位語從句只能用whether不用if；引導(dǎo)賓語從句時，一般二者均可。 What the doctors really doubt is _ my mother will recover from the serious disease soon. A. when B. how C. whether D. why _ well go camping tomorrow depends on th

3、e weather. A. If B. Whether C. That D. Where （2）介詞后的賓語從句用whether不用if。 They are worried about whether they can pass the exam. （3）whether后可緊跟or not,也可將or not放在句末; if不與or not 連用。 We havent decided whether or not we will go out for a drive. (=We havent decided whether we will go out for a drive or not.)

4、 (4）賓語從句放在句首時，只用whether不用if。 Whether she is married, I dont know. (5) 賓語從句是否定句時用if, 不用wheth-er。 I wonder if he wasnt hurt in the accident. 2. that與what that 在名詞性從句中只起連接作用，不作任何成分，that在賓語從句中常省略; what=the thing(s) that (所的東西), 既起連接作用，又作句子成分，不能省略。 Little Tommy was reluctant to tell the schoolmaster _ he

5、 had done the day before. A. that B. how C. where D. what _ caused the accident is still a complete mystery. A. What B. That C. How D. Where 3. how 與 what how 在從句中作方式狀語，what作主語、賓語或表語。 A computer can only do _ you have instructed it to do. A. how B. after C. what D. when Do you remember _ he came? Ye

6、s , I do, he came by car. A. how B. when C. that D. if 4. whoever, whomever, whatever, whichever whoever (=anyone who), whomever(=anyone whom), whatever (=anything that), whichever (=the one which)也可引導(dǎo)名詞性從句,它們分別是 who, whom, what, which 的強調(diào)用法。 These wild flowers are so special I would do _ I can to s

7、ave them. A. whatever B. that C. which D. whichever It was a matter of _ would take the position. A. who B. whoever C. whom D. whomever 5. why與because why是連接副詞，because連詞, 都可引導(dǎo)表語從句。 _ she couldnt understand was _ fewer and fewer students showed interest in her lessons. A. What; why B. That; what C. W

8、hat; because D. Why; that He was absent for the meeting. Thats because he was ill. 三、it作形式主語或形式賓語 1.英語中經(jīng)常用it 作形式主語，提在前面,把真正作主語的從句放在句末。 _ is a fact that English is being accepted as an international language. A. There B. This C. That D. It I read about it in some book or other, does it matter _ it wa

9、s? A. where B. what C. how D. which 2.如果賓語從句后有賓語補足語等成分，常用it 作形式賓語放在賓語原來的位置上，將賓語從句置于后面;某些詞后有時無賓語補足語等成分，也用it 作形式賓語。 He tried to make it clear to us which is correct and which is incorrect. I hate _when people talk with their mouths full. A. it B. that C. these D. then 四、時態(tài)呼應(yīng) 1.主句的謂語是現(xiàn)在時態(tài)、將來時態(tài)或主句為祈使句等，

10、賓語從句可用它所需要的時態(tài)。 Please tell me when the plane will take off. Can you make sure _ the gold ring? A. where Alice had put B. where Alice has put C. where had Alice put D. where has Alice put 2. 主句是過去時，賓語從句應(yīng)用過去時態(tài)的某種形式。 We were all surprised when he made it clear that he _ office soon. A. leaves B. would

11、leave C. left D. had left The police found that the house _ and a lot of things _. A. has broken into; has been stolen B. had broken into; had been stolen C. has been broken into; stolen D. had been broken into; stolen 3.若賓語從句敘述的是客觀事實或真理,即使主句用過去時，從句仍用一般現(xiàn)在時。 When I was a child, I knew the sun rises in the east and sets in the west. 五、語氣 suggest（建議)，order（命令)，advise （勸告）,demand（要求)，insist（主張）等動詞的賓語從句及suggestion, order等作主語時，其后的表語從句、同位語從句常用虛擬語氣“(should ) do”；suggest作“暗示，表明” 時，其賓語從句用真實語氣。 Janes pale face suggested that she _ ill, and her
