1、【考点点拨】名词性从句可分为主语从句、宾语从句、表语从句和同位语从句。近几年高考对名词性从句的考查重点如下：,【考点1】名词性从句中引导词that与what的使用场合。,1 that 引导名词性从句时，不在从句中充当任何成分，只起连接作用；而what是连接代词，在从句中充当成分。 _ made the school proud was _ more than 90% of the students had been admitted to key universities. (2003上海春季) A. What / because B. What / that C. That / what D

2、. That / because,2that在主语从句、表语从句和同位语从句中不可省略, 但当有两个和两个以上的宾语从句并列时，第二个从句以下的that不可省略。 如：She said (that) she had left school and that her parents would find her a job. Word comes _ a group of Australian guests will come to visit our school next week. A. thatB. whichC. 不填D. about which (2005天津2月),3介词后的宾语从

3、句常用what，whether引导，不用that，which引导。但在介词besides，except，in后可用that引导宾语从句。在有it作先行词时，that可用来引导介词后的宾语从句。 The other day, my brother drove his car down the street at _ I thought was a dangerous speed. A. asB. which C. what D. that (2004上海春季),【考点2】名词性从句中引导词whether与if 的用法区别。,可以互换的场合： A.引导及物动词或形容词后的宾语从句 He is no

4、t sure if / whether he can manage to do it. B.当与or not分开使用时 He wondered if / whether we will attend the meeting or not. 只能用whether不能用if的场合： A.引导表语从句、同位语从句及位于句首的主语从句引导介词后的宾语从句（有时可省略） B.后面紧跟or not时 C.后面直接跟动词不定式时, _ the flight to New York will be delayed is _ Im especially worried about. (2003南京) A. If

5、 ; whatB. Whether ; thatC. When ; thatD. Whether ; what I dont know whether to go there at once. 我不知道是不是该立刻去那里。 (河北：李亚男),虽引导宾语从句，但为了强调宾语部分，也可把从句放在句首，此时只用whether不用if。 Whether he will come I am not sure.他是不是来我拿不准。,从句作介词宾语时只用whether不用if。 It depends on whether it will be fine.那得看是不是晴天。,作discuss等动词的宾语时，用

6、whether不用if。 We discussed whether we should close the shop.我们讨论是不是该关掉商店。,句子中有if引导的条件句，如再有表示“是否”的宾语从句，用whether不用if。 He asked me whether Id move to New York if I got the job.他问我如果我得到那份工作是否会搬家到纽约。,如果宾语从句为否定句时，则只用if不用whether。 I dont know if it wont rain tomorrow.我不知道明天是不是会下雨,在引导主语从句、表语从句、同位语从句时一般用whethe

7、r不用if。如： Whether it is true remains a question.(主语从句)那是不是真的还是个问题。 The question is whether it is true.(表语从句)问题是是不是真的。 We have a doubt whether it is true.(同位语从句) 我们怀疑那是不是真的。 注:whether引导主语从句放在主句之后时可用if来代替。 It is unclear whether/if he likes the present.他是不是喜欢那个礼物还不清楚。,【考点3】,在动词：一坚持（insist）、二命令（order，com

8、mand）、三建议（suggest，advise，propose）、四要求（demand，require，request，ask）后的宾语从句和这些动词的过去分词后的主语从句，以及这些动词的名词引出的表语从句和同位语从句中，谓语部分常用（should）do形式。 I advised that he _ to the hospital at once, but he insisted that he _ quite well then. A. be sent; was feelingB. was sent; sent C. be sent; feelD. should be sent; shou

9、ld feel (2005年山东2月),【考点4】,名词性从句的语序只能是陈述句语序，宾语从句的时态应该与主句的谓语动词的时态保持一致。 They are teachers and dont realize _ to start and run a company. (2004 黄冈) A. what takes itB. what they takeC. what takes themD. what it takes,【考点5】,whoever，whichever，whatever，whenever，wherever和however在引导名词性从句时不可与no matter who / wh

11、词在定语从句中的作用；特别注意指代整个主句内容的关系代词which引导的非限制性定语从句。 I shall never forget the day _ Shenzhou V was launched, _ has a great effect on my life. A. when; whichB. that; whichC. which; thatD. when; that (2004北京东城),【考点7】,关系代词that，who，which以及as的用法区别。 指人时常只用who不用that的情况； 指物时只用which不用that的情况； 只用that不用which的情况； 关系代词

12、as与which的用法区别； the same that 与the same as 的区别 There is no such place _ you dream of in all this world. (2004北京西城5月) A. that B. whatC. whichD. as,【考点8】区别that引导的定语从句与that引导的同位语从句。,that引导同位语从句时，that是纯连词，在从句中不充当任何成分；that引导定语从句时，that是关系代词，在从句中充当主语或宾语等。 比较： The news that they had won the game arrived soon

13、. The news that you told me yesterday is true. Is this the reason _ at the meeting for his carelessness in his work?

15、he way which,答案：BACDA DAADA DA,1The boy dived into the water and after _ seemed to be a long time, he came up again. A. what B. thatC. itD. which 分析：句中的after用作了介词，后接的从句应该是宾语从句。这个从句少主语，所以应该用what来引导。选A.that引导宾语从句时，不充当句子成分。,2These two areas are similar _ they both have a high rainfall during this season. A. except thatB. in whichC. in that D. so that 介词后的宾语从句常用what，whether引导，不用that，which引导。但在介词besides，except，in后可用that引导宾语从句。在有it作先行词时，that可用来引导介词后的宾语从句。,3You may depend on _ that all the goods will be shipped abroad in time.
