2.名词性从句分类练习篇二

名词性从句:在复合句中起名词性作用的从句叫名词性从句。名词性从句可在句中作主语、宾语、表语或同位语, 所以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。

定语从句:用来修饰主句中某一名词或代词 (有时也可修饰整个主句或主句中的一部分) 而起定语作用的句子叫作定语从句。

二、引导词

引导名词性从句的有:

连接词, 如that, whether, if (不充当从句任何成分) 等。

连接代词, 如what, whatever, who, whoever, whom, whose, which等。

连接副词, 如when, where, how, why等。

引导定语从句的有:

关系代词, 如who, whom, whose, that, which, as等。

关系副词, 如when, where, why等。

三、引导词在从句中的作用

1.名词性从句

(1) that, whether和if。

连接词that本身没有意义, 在从句中不充当任何句子成分, 在宾语从句中有时可省略。

whether可以引导所有的名词性从句, 而if只能引导宾语从句。

whether引导的宾语从句可作介词的宾语, 而if则不能。

if既可引导定语从句, 也可引导宾语从句。如果用if会引起歧义, 应避免使用if, 而用whether。

(2) 连接代词who, whom, whose, what, which等在从句中既起连接作用, 同时又担当主语、宾语、定语、表语等成分。

(3) 连接副词where, when, how, why等在从句中既是连接词, 又作状语。

连接代词whoever = anyone who任何人, 无论谁;whatever =anything that凡是, 无论什么;whichever = anything that无论哪一个, 任何一个;whomever = anyone whom (whoever的宾格形式) 。

2.定语从句

(1) 关系代词who, whom 和that代替的先行词是物或人的名词或代词。

(2) whose 用来指人或物, 只用作定语, 若指物, 它还可以同of which互换。

(3) which, that所代替的先行词指事物, 在从句中可作主语、宾语等。

(4) when, where及 why分别指时间、地点和原因, 在定语从句中作时间状语、地点状语和原因状语。

四、定语从句与宾语从句的区分

1.通过从句的位置来判断

定语从句的位置通常在名词、代词的后面, 而宾语从句的位置一般在动词或者介词短语之后, 因为宾语一般都在动词或者介词短语之后。

2.通过引导词来判断

定语从句的关系代词只有that, who, which, whom, 关系副词也只有when, where, why, 所以如果有的从句是whether, if, how, what等词引导的, 肯定不是定语从句。

3.通过从句的成分来判断

都是that引导的从句, 宾语从句和定语从句也有区别, 我们可以通过that在从句中充当的句子成分判断。

如:I know that you are right. that引导的是一个宾语从句, that只是连接词, 不充当任何成分, 所以that后面的句子“you are right”是一个主语谓语完全的句子。

五、同位语从句和定语从句的区分

1.从语法功能上区分

定语从句是形容词性的从句, 是对前面名词的性质、特征进行描述, 它与先行词是修饰与被修饰的关系;而同位语从句是名词性从句, 是对前面名词作进一步的补充性解释说明, 它与前面的名词是同位关系, 即前面名词是从句的概括总结, 从句是前面名词的具体内容, 且名词与该同位语从句有逻辑上的主表关系。

2.从先行词上区分

定语从句的先行词没有限定, 举不胜举, 而同位语从句的先行词仅限于具有一定内容的抽象名词, 如idea (想法, 主意) , hope (希望) , thought (想法) 等。

3.从引导词上区分

3.名词性从句（二）篇三

名词性从句除了由连词that, whether 或if引导之外，还可以由连接代词 who, whom, whose, what，which, whoever, whomever, whatever, whichever等和连接副词when, where, why, how, whenever, wherever, however, because, as if等引导。

请看几个例句：

What was said here must be kept secret.

He can’t tell which method they will use for the experiment.

The problem is how much we should charge for the new mobile phone.

We haven’t yet settled the question where we are going to spend New Year’s Day．

以上几个句子中的划线部分分别是主语从句、宾语从句、表语从句和同位语从句。

使用连接代词或连接副词引导名词性从句时，要注意以下几点：

（一）从句的语序

1. _______ is not known yet.

A. Where has she gone

B. Where she has gone

C. How did she leave

D. Why did she go

2. We don’t know_______.

A. this is whose dictionary

B. whose dictionary is this

C. whose dictionary this is

D. whose is this dictionary

提示答案为B;C。在名词性从句中, 除了关联词要提到句首之外, 一律要用陈述句语序。当关联词含疑问意义时, 初学者就会受习惯影响错误地使用疑问句语序。克服这种错误的关键是要找准从句中的主语和谓语。

（二）连词的选用

3._______ you did it is not known to all.

A. Who B. What

C. Which D. How

4. The question came up at the meeting_______ we had enough money for our research.

A. that

B. whether

C. which

D. if

5. —What were you trying to prove to thepolice?

—______ I was last night.

A. That

B. When

C. Where

D. What

提示答案为D;B;C。连词的选用要依据上下文所表述的内容及其该连词在从句中的作用而定。连词that, whether或if引导名词性从句时只起连接主句与从句的作用，在从句中并不担任句子成分。与that, whether或if不完全相同的是，连接代词who, whom, whose, what，which, whoever, whomever, whatever, whichever等和连接副词when, where, why, how, whenever, wherever, however等在名词性从句中既起连接主句与从句的作用，又在从句中担任句子成分，而且各自还保留原来疑问词的含义。

（三）时态、语态

6. We were all surprised when he made it clear that he_______ the office soon. A. leaves

B. would leave

C. left

D. had left

7. —He ran into a tree on his way home.

—I suppose he_______ too fast.

A. drives

B. was driving

C. drove

D. had driven

8. The teacher said that light______ faster than sound.

A. has traveled

B. traveled

C. had traveled

D. travels

提示答案为B;B;D。一般说来，从句的谓语动词时态受主句谓语动词的影响。如果主句的谓语动词是一般现在时，从句中的谓语动词可以用各种时态；如果主句中的谓语动词用了一般过去时，则从句中的谓语动词通常用与过去相关的某种时态形式，但如果从句表达的是客观真理或客观存在则不受此影响。

（四）特殊的谓语动词形式

9. It is required that mobile phones_______ in their school.

A. should not use

B. aren’t used

C. won’t be used

D. not be used

10.—Don’t you want to go to a karaoke bar with us?

—I wish I_______, but I have an appointment.

A. may

B. could

C. can

D. should

11. When a pencil is partly in a glass of water, it looks as if it _______.

A. breaks

B. has broken

C. were broken

D. had been broken

提示答案为D;B;C。与advice, advise, insist（坚持要），order, request, require, suggest（建议），suggestion等词有关的从句中，谓语动词通常采用“should + 动词原形”的形式，且should可以省略；wish，would rather后宾语从句及as if/though引导的表语从句中谓语动词用过去式表示现在（be用were），用过去完成式表示过去。

（五）双重连词的使用

12. He said a lot, but I didn’t understand  he said meant.

A. all that

B. what what

C. what that

D. that what

13. He said_______I did not have time I might not go.

A. that

B. if

C. that if

D. that whether

提示答案为B;C。所谓“双重连词的使用”是指在一个名词性从句中包含另一个从句，而且引导两个从句的词紧紧相连。值得注意的是，除了依据上下文所表述的内容及其在从句中的作用而确定连词外，紧紧相连的两个连词一个都不可省略。

在使用连接代词或连接副词引导名词性从句时，初学者容易混淆下列几组词，请注意他们之间的区别：

(一)that, what

14. Each blind man believed_______ he knew just_______ the elephant looked like.

A. that; what

B. what; that

C. that; that

D. what; what

15. After______ seemed like hours he came out with a bitter smile.

A. which

B. it

C. what

D. that

提示答案为A;C。that和what都可以引导名词性从句，但that是连词，本身无词义，仅起连接主句和从句的作用，不在从句中担任任何成分；what是连接代词，不仅起连接主句和从句的作用，而且在从句中充当一定的成分，如主语、宾语或表语。what除了保留其疑问的含义外，还有the thing(s) which或all that之意，可以用来表示“……的时间、……的地点、……的人、……的速度”等。

(二) what(ever), which(ever)

16. Dr Black comes from either Oxford or Cambridge. I can’t remember _______.

A. where

B. there

C. which

D. that

17. It is generally considered unwise to give a child _______ he or she wants.

A. however

B. whatever

C. whichever

D. whenever

提示答案为C;B。一般说来，what(ever)不强调限定范围，而which(ever)则表示在一个限定范围内进行选择。

(三)who, whoever, whomever

18. It was a matter of_______ would take the position.

A. who

B. whoever

C. whom

D. whomever

19. This old computer must have been of great use to_______ did the scientific research.

A. those

B. when

C. whoever

D. whomever

提示答案为A;D。作为引导名词性从句的连接代词，who仍然保留着其疑问的含义，而whoever的含义是anyone who，强调任何一个人，没有疑问的含义。who和whoever在从句中通常作主语，口语中可以代替whom和whomever作宾语，但whomever只能作宾语。

(四) whatever, whoever等；no matter what/who等

20._______ David says sounds right to Helen. That’s why she has made up her mind to leave withhim______ happens.

A. Whatever; no matter what

B. No matter what; whatever

C. No matter what; no matter what

D. Whatever; however

提示答案为A。连接代词whoever，whatever可引导名词性从句，相当于anyone who, anything that等。他们也可以引导让步状语从句，相当于no matter who/what。但no matter who/what/which等只能引导让步状语从句。

答案与解析

1. C 考查宾语从句。由于宾语从句部分句子结构完整无缺，所以用that引导。

2. D what引导主语从句，并作从句的主语；that引导表语从句，只起连接主句与从句的作用，在从句中不作成分。

3. D 第一空所填之词作主语they的同位语，表示前文提到的两趟公共汽车，意思是“两个都……”，用both；第二空所填之词引导宾语从句，引导词在从句中作定语，修饰代词one，又由于有限制性范围（Bus No.9 or No.12），所以用whichever。

4. C 根据句意可知此句空白处用how引导表语从句。

5. C is后面是表示地点的表语从句。假如看作定语从句而选择the place，其后应加上where 或in which。

注意：受固定思维的影响，做本题时很容易把表语从句看作定语从句。解决办法是看原句中有没有先行词，引导词在从句中作什么成分。

6. A that the satellite Chang’eⅠ has beensuccessfully sent up to circle the moon是the news的同位语，对其内容加以解释。that在从句中没有词义，也不作成分，但不能省略。

7. D that引导同位语从句。第二空用those who填空，those who come first in this book fair中的those作be given to的宾语，who引导定语从句修饰those。如将题干中的come改成comes，则第二空可以用anyone who或whoever。

8. B 所填之词引导从句作discuss的宾语，同时在从句中充当主语；由于该词只表示疑问，不表示强调，所以用who而不必用whoever。

9. B what引导名词性从句作介词to的宾语，同时在从句中作主语。what的含义相当于the place that。

10. B 第一空所填之词引导表语从句，由于从句意思完整，因此选用that；从句中的动词受suggestion的影响，须采用“should + 动词原形”的形式，且should可以省略。

11. C 该题测试宾语从句中动词的特殊表达形式：would rather，wish后宾语从句中谓语动词用过去式表示现在，用过去完成式表示过去。

12. A 该题测试引导名词性从句的that和what的用法：that只起连接主句与从句的作用,在从句中并不担任句子成分; what既起连接主句与从句的作用，又在从句中担任句子成分。该题中，what is troubling me 是主语从句，what在从句中作主语； that I don’t understand what he said是表语从句；what he said是表语从句中动词understand的宾语，what在从句中作said的宾语。

13. A 该句空白处所填的词引导主语从句，并且在从句中作主语，所以用whatever，而不用no matter what。

4.名词性从句分类练习篇四

◆典型陷阱题分析◆

1.She was so angry and spoke so fast that none of us understood _______ he said meant.A.that B.what

C.that that D.what what 【陷阱】可能误选B。许多同学一看选项首先就排除了C和D，认为这样两个“引导词”叠用的情况不太可能。在A和B两个选项中，选项A肯定不行，因为它引导宾语从句时不能充当句子成分，所以便选择

了B。

【分析】正确答案选 D。第一个what 用作动词 meant 的宾语，第二个what 用作动词 said 的宾语，即在 none of us understood what what he said meant 中，none of us understood 为主句，what what he said meant 为宾语从句，而在此宾语从句中又包括有 what he said 这样一个主语从句。

2.After _______ had happened he could not continue to work there.A.which B.how C.what D.having

【陷阱】可能误选A。

【分析】最佳答案选 C。有的同学误选A，是因为认为介词后应接关系代词 which，但实际上，若填关系代词，其前没有先行词，这根据不是一个定语从句。另外，由于 had happened 缺主语，所以B和

D也不能选。请再做下面一题(答案选B)：

He pointed to ______ looked like a tomb and said, “Ghost.”

A.that B.what C.which D.as 3．“Is ______ you want to say?” asked the teacher.A.this B.that C.all that D.that all

【陷阱】根据中文字面意思误选A或B。

【分析】最佳答案选 D。假若选A或B，那么转换成陈述句即为：This is you want to say./ That is you want to say.显然句中的两个谓语动词 is与want相冲突。选D组成的句子是 Is that all you want to say? 其中的that 为句子主语，all 为表语，you want to say 为定语从句，用以修饰all。

4.“When ______ leave for Japan?” “When ______ leave for Japan is kept secret.”

A.they will, will they B.will they, they will C.they will, they will D.will they, will they 【陷阱】可能误选D，认为 when 后应用疑问句词序。

【分析】最佳答案选 B。第一个when引出的是一个特殊疑问句，故用疑问词序；第二个 when 引出的是主语从句，故其后用陈述句词序。请做以下试题(答案选C)：

(1)None knows if _______ that boy, but if _______ him, her parents will be disappointed.A.she will marry, she will marry B.she marries, she marries C.she will marry, she marries D.she marries, she will marry(2)“Where _______ go to work?” “Where _______ go to work is not known.”

A.we shall, we shall B.shall we, shall we C.shall we, we shall D.we shall, shall we 5.Someone is ringing the doorbell.Go and see ______.A.who is he B.who he is C.who is it D.who it is

【陷阱】几个干扰项均有可能误选。

【分析】此题最佳答案为D。首先可以排除A和C，因为空格处实为一个宾语从句，所以不能用疑问句词序。另一方面，但按英语习惯，当用于指代身份不明的人时，要用代词it，而不用 he 或she等。

比较以下两句：

Mr Smith is at the door.He wants to see you.史密斯先生在门口，他想见你。Someone is at the door.It may be the postman.有个人在门口，可能是邮递员。第一句因前面指明了是 Mr Smith，所以后面用代词 he；而第二句因前面用的是不定代词

someone，说明此人身份尚不明确，故其后用了代词 it 来指代。

6.Don’t you know, my dear friend, ______ it is your money not you that she loves?

A.who B.which C.that D.what 【陷阱】此题容易误选 A或B：选 A 的同学认为这是指人的，故用who；选B的同学认为这是非限制性定语从句，两者都是误认为这是定语从句(注意没有先行词)。

【分析】其实答案应选C。that引导的是一个宾语从句，用作动词 know 的宾语，它只是被句中的插入语 my dear friend 隔开罢了。请做以下试题(答案均为C)：

(1)Everyone knows, perhaps except you, _______ your girl-friend is a cheat.A.who B.which C.that D.what(2)I think, though I could be mistaken, ______ she liked me.A.who B.which C.that D.what

(3)He told me the news, believe it or not, ______ he had earned $1 000 in a single day.A.that B.which C.as D.because 前面两题 that 引导宾语从句，后面一题 that同位语从句(修饰the news)。

【答案与解析】

1.选D。what made matters worse 是主语从句(注意其后有谓语动词was)，相当于 the thing that

made matters worse。

2.选A。what 引导的是表语从句，相当于 the thing that it takes to do anything well。

3.选C。that 引导的是一个主语从句，句首的it为形式主语。

4.选 C。答句为省略句，其完整形式为 I was trying to prove to the police where I was last night，在此 where 引导的是一个宾语从句。类似地，下面选 C：

“_______ made her struggle to become an artist so hard?” “______ she was a woman.”

A.What, What B.That, That C.What, That D.That, What 5.选D。what 引导的是表语从句，what 在此相当于 the things that。

6.选 C。句首的 it 是形式主语，空格处所填词用于引导主语从句。由于该主语从句中又缺主语，故排除A、B、D。（注意：不能选 A，因为 that 引导名词性从句时不能充当句子成分）7.选 A。第一空填 what，是因为该主语从句中的动词 understand 缺宾语；why 和 because 均可引导表语从句，其区别是： why 引导表语从句强调结果，because 引导表语从句强调原因。句中空格

后文表明的是结果，故用 why。

8.B。what 在此引导主语从句且在从句作宾语，它相当于 the thing that。

9.B。两空均填 what，均用于引导宾语从句，因为两个宾语从句中的动词 said 和do 均缺宾语，而在各个选项中只有 what 可用作宾语。

10.选 A。what 引导宾语从句。由于动词 wants 缺宾语，所以填 what。句意是：当你找工作面试回答问题时，请记住这条黄金定律：永远给予对方确实想要的东西。

11.选 A。I can to save them 为 I can do to save them 之略，此句中的 do 缺宾语，故选

whatever。

12.选 B。that 在此引导主语从句，无词义，也不充当句子成分。注意不要根据中文意思选 D，因

为 because 不用于引导主语从句。

13.选 C。两个空格处均为引导宾语从句的引导词，而四个选项中两者可引导宾语从句的只有 C。14.选 B。比较 That’s why… 与 That’s because…：前者用于强调结果，后者用于强调原因。如

下面一题选 D：

I got wet all through._______ I had neither a raincoat nor an umbrella.A.It’s the reason B.That’s why C.There’s why D.That’s because

15.选 D。由 is worth praising 这一谓语可知前面是主语从句，排除不能引导从句的 B 项和 C 项；whoever 引导主语从句表示“任何……的人”，在此它相当于 anyone who。

5.名词性从句篇五

一：名词性从句：在句子中起名词作用的句子叫名词从句。名词从句的功能相当于名词词组，它在复合句中能担任主语、宾语、表语、同位语等，因此根据它在句中不同的语法功能，名词从句又可以分为主语从句、表语从句、宾语从句和同位语从句。

主语从句：作主语的从句叫主语从句，它一般放在句首，也可以用it作形式主语，主语从句放在主句后面。Who will win the match is still unknown.It is still unknown who will win the match.Whether she will leave for Beijing hasn’t been decided..宾语从句：作宾语的从句叫宾语从句，它位于及物动词或介词后面。也可用it作形式宾语，宾语从句后移。He don’t know what he wants.下列四种情况须用it 作形式宾语： ① 当不定式（短语）、动名词（短语）或从句在复合宾语结构中作某些动词的宾语时（如think, make, find, consider, feel, suppose等）；

e.g.They found it pleasant that they worked with us Chinese.I don’t feel it difficult to understand the Special English.He makes it a rule never to borrow money.② 某些表示“喜、怒、哀、乐”的动词，如like, enjoy, love, hate等，往往不能直接接宾语从句；e.g.I don’t like it that he’s so lazy.I hate it when my mother asks me to eat eggs.③ that引导的宾语从句不能直接作介词的宾语； e.g.You may depend on it that we shall always help you.Would you see to it that she gets home early?

He insisted on it that he was innocent.④ 由及物动词与介词组成的固定搭配中，宾语从句若作该动词的宾语时，须借用it。We owe it to you that there wasn’t a serious accident.表语从句：作表语的从句叫表语从句，它位于系动词之后。

同位语从句：作同位语的从句叫同位语从句，同位语从句说明其前面的名词的具体内容，前面名词是抽象名词：advice,news,fact,truth,word等。Word came that he won the match.通过分析下列从句所在的位置，判断下列句子分别是什么从句，并试着翻译。1.What he did satisfied everybody.2.Whether she will leave for Beijing hasn’t been decided.3.I want to know what he has told you.4.Could you show me how I can reach the station.5.Everything depends on whether we have enough money.6.The question is when he will come.7.He looks as if he is very angry.8.That’s what he wants.9.The news that we won the game is exciting.10.The doctor gave him a suggestion that he(should)give up smoking.11.I have no idea where he has gone.二：引导词：用上面例句练习引导词的用法。连接词 that(无实意，在从句中不作成份，只起引导作用)whether/if(是否)as if/as though, because(只引导表语从句)连接代词

what（什么；……的……, 在名词性从句中作主语、宾语、表语、定语）I don’t know what foreign language we’ll learn at college.Which(哪一个，在名词性从句中作主宾表定)who(谁，主宾表)Whose(谁的，定语)Whom(谁，宾语)Whatever=anything that(无论什么)Whichever(无论哪一个)Whoever=anyonewho(无论谁)。连接副词 when(什么时候，何时)where(什么地方，何地)why(为什么)how(如何，怎样)三：注意：1.在名词性从句中，疑问语序变成陈述语序（主语+谓语）。①When he will leave for Beijing hasn’t been decided.②I don’t know where he comes from.③The question is what he wants.④I have no idea when he will be back.2.Whether和if引导名词性从句的时候都是“是否”的意思，但下列情况只能用whether.1.引导主语从句并放在句首时。Whether there is life on the moon is an interesting qustion.It is an interesting question whether/if there is life on the moon.2.从句在介词后面时。Everything depends on whether we have enough money.3.引导表语从句时。The question is whether he will like the gift.4.引导同位语从句时。I have no idea whether the meeting will be held.5.从句后有“or not”时。It remains to be seen whether or not he will succeed.6.后接动词不定式时。He doesn’t know whether to trust her words.3.名词性从句中的省略

在由连接词that引导的宾语从句中，可以把that省略。但如从句是并列句时，第二个分句前的that不可省。例如：He says(that)he often runs in the morning and that he always runs as fast as possible.4.表建议、命令、要求的词后的从句的谓语动词常用（should）+动词原形。Suggest、advise、command、order、demand、require、request等。The general ordered that troops(should)set off at once.The doctor gave him a suggestion that he(should)give up smoking.The suggestion is that he(should)give up smoking.It is suggested that he(should)give up smoking.5.What的用法

什么;

……的……

1.What make the school proud was that more than 90% of the students had been admitted to key universities.2.The city is not what it used to be.3.She is not what she was 5 years ago.4.This is what we should do(all that)

5.What he wants is a book.6.I don’t know what foreign language we will learn at college.6.Who与whoever引导名词性从句的辨析：Who broke the window is unknown.Whoever(Anyone who)breaks the law will be punished.Whoever told you about it was lying.What与whatever 后者比前者语气强What she did was right.Whatever she did was right.7.Whoever /whatever/whichever即可引导名词性从句，也可以引导让步状语从句。引导让步状语从句时可以与no matter+疑问词互换。分析下列句子是名词性从句还是让步状语从句。Do it whatever other say.Whoever breaks the law will be punished.Whatever he did was right.Whatever happens, we shall not lose heart.Whoever comes, he will be welcome.He would believe whatever I said.Whatever the weather is like, we’ll go camping.However busy he was, he studied English every day.四：1.主语从句中的主谓一致

When and where I will go hasn’t been decided.When I will leave and where I will go haven’t been decided.2.宾语从句中的时态呼应

当主句动词是现在时，从句根据自身的情况而使用不同时态。

I know(that)he studies English every day.I know(that)he studied English last term.I know(that)he will study Enlishi next year.I know(that)he has studied English since 1998.当主句动词是过去时态（could, would除外），从句则要用相应的过去时态（一般过去时，过去进行时，过去将来时，过去完成时），当从句表示的是客观真理，科学原理，自然现象，则从句仍用现在时态。The teacher told us that nothing is difficult if we put our hearts into it.The teacher told us that Tom had left us for America two weeks before.He said that light travels much faster than sound.4.做形容词后的定语从句，形容词后的介词要去掉

I’m afraid(that)I’v made a mistake.He is pleased with his great achievement.He is pleased that he has achieved so much 5.当主句的主语是第一人称，并且主句的谓语动词是think, believe, imagine,suppose等动词，这时要进行否定转移（把对从句谓语动词的否定转移到主句谓语动词上）。We don’t think you are here.I don’t believe he will do so.6.That引导同位语从句和定语从句的区别：that在定语从句中作成分（主宾表）；that在同位语从句中不作成分，只起引导作用。We heard the news that he won the game.We heard the news that he had told her.1．____he does has nothing to do with me.A.whatever B.No matter what C.That D.If 2.The manager came over and asked the customer how____

A.did the quarrel came about

6.名词性从句教案(定) 篇六

一、学情分析

教学对象为高中三年级学生，智力发展趋于成熟。他们的认知能力有了进一步的发展，渐渐形成用英语获取信息、处理信息、分析问题和解决问题的能力。他们学习英语方法由死记硬背转型向理解型并应用到交际上，他们有自己的学习技能和策略，学会把语言学习与现实生活和兴趣联系起来。通过任务型课堂活动和学习，学生的学习自主性得到加强，不再认为英语的课堂学习很枯燥，主动参与到活动中去，成为课堂的主体，同时也加强了与他人交流合作的能力。学生已经完成了高中英语两年多的学习，渐渐习惯了教师的教法。他们会对课堂内容提出自己的疑惑和勇于阐述见解，并且从课内知识拓展到课外，通过多种渠道获取学习资源。不过，本班学生的水平参差不齐，两极分化现象较严重。因此在教学过程中，布置的任务要兼顾各个层次的学生，使他们都有所收获。

二、教材分析

复习课的内容一般比较丰富，既要复习已学的知识，更重要的是将已学的知识进行总结、归纳，找出其内在联系，及其规律。并在此基础上结合考点去扩展知识、指导实践，从而使学生对知识掌握得更加深刻更加牢固。根据学生水平和教学设计进行整合或增减，让不同层次的学生在课堂上都有所收获。

1.整理语法笔记

2.语法练习一张（要求：限时完成2个/min）课后反思：

改错:(名词性从句在改错题中的运用)1.Here is my idea about how a friend is like.(2010重庆卷)2.I have no lectures this morning so I think I’d email you and let you know what things are going.（2009宁夏卷）

1.The Black Country is about 10 miles from Birmingham.Historically, it was famous for industry, which explains __16__ the area is called the Black Country.（2011广州一模）

7.全面剖析名词性从句篇七

其用法相当于名词的从句叫名词性从句。根据它在句中不同的语法功能可分为主语从句、宾语从句、表语从句和同位语从句等。如：

Where cars will be parked in the future is a question. （主语从句）

I think that watching TV too much is bad for people’s health. （宾语从句）

Wenchuan is not what it used to be after the earthquake. （表语从句）

Along with the letter was his promise that he would visit me this coming Christmas. （同位语从句）

2. 名词性从句应注意的几个问题

（1）引导词。引导名词性从句的连接词可分为三类：①that ②if / whether ③wh-疑问词。引导词必须位于名词性从句的最前面。

（2）语序。名词性从句采用陈述句语序，即“主语＋谓语”。如：

I really don’t know_____I kept the secret papers.

A. where was it

B. it was where that

C. where it was that

D. where was it that

【解析】 C考查宾语从句。根据引导词一定要位于从句的最前面，排除B项；又因为要用陈述句语序，排除A和D项，故C项正确。

（3）时态一致。当主句的谓语动词是一般现在时时，从句的谓语动词可根据情况使用各种时态；当主句的谓语动词是一般过去时时，如果从句表述的不是一个客观事实或真理，其谓语动词也必须用某种过去时态。如：

The man insisted that the lady_____his wallet and that she_____to the police station.

A. steal； should be taken

B. stole； be taken

C. stole； should take

D. should steal； should take

【解析】 Binsist后接宾语从句表示“坚持……，主张……应该……”（即该动作尚未发生）时，从句谓语动词用“（should）＋动词原形”，should可省略；insist意为“坚持说……，认为……”，表示事实时，从句谓语动词根据情况选择使用适当时态。由本句句意可知第一个that从句表示的是“坚持说……”，而主句谓语动词是一般过去时，根据时态一致原则第一空应用一般过去时，排除A和D项；第二个that从句表示“主张……”，故选B。

1. 名词性从句中that与what的区别

① When faced with life-and-death decisions，

a teacher can be expected to do is to protect students with his or her own life.

A. thatB. what

C. howD. whether

【解析】 B考查主语从句。本题主语从句中连接词作宾语，排除作状语的how和不充当句子成分的whether。that引导主语从句时在句中也不充当成分，故选择B。

② It is difficult to fill the kids’ minds with the idea_____they must love study.

A. whichB. what

C. whetherD. that

【解析】 D名词idea后的从句不缺少句子成分，由此可断定是同位语从句，故选择连接词that。

点拨名词性从句中that与what的区别是：

（1） that在名词性从句中不充当句子成分，只起连接作用；而what在名词性从句中不仅起连接作用，也充当句子成分，如主语、宾语、表语等。

（2） that在主语从句、表语从句和同位语从句中不可以省略，但如果有两个或两个以上的宾语从句并列时，第二个从句（及以下）中的that不可以省略。如：

She said （that） she had left school and that her parents would find her a job.

2. 名词性从句中的it作形式主语或形式宾语

① Why don’t you bring_____to his attention that now students are bearing too heavy a study load？

A. itB. this

C. thatD. what

【解析】 A考查it作形式宾语的用法。“that now

students are bearing too heavy a study load”是真正的宾语。that和this不能作形式宾语。

②_____disappeared as time went on that he was afraid of climbing high mountains.

A. ItB. That

C. WhatD. Which

【解析】 A考查it作形式主语的用法。句中that引导的从句是真正的主语。

点拨在名词性从句中，为了保持句子的平衡，往往用it作形式主语或形式宾语，而把真正的主语或宾语放到后面，尤其是that引导的主语从句常用it作形式主语。

（1）动词find，feel，consider，make，believe等后面有宾语补足语时，需要用it作形式宾语，而将that宾语从句后置。如：

I think it necessary that we drink plenty of hot water every day.

（2）主语从句一般位于句首，但有时可以用it作形式主语，而把主语从句后置。这种用法通常用于“It’s+名词/形容词/过去分词+主语从句”句型中。如：

It’s reported that the president would come to visit our school.

It’s certain that he will attend the meeting.

3. 名词性从句中whether与if的区别

you go or stay at home won’t make any difference.

A. IfB. When

C. ThatD. Whether

【解析】 D考查主语从句。本句不缺任何成分，排除作状语的when；if不能引导主语从句，也排除。whether引导主语从句时只起连接作用，虽有意义，但不充当句子成分，故选D。

点拨whether与if表示“是否”时的区别：

两者都没有实际意义，在引导宾语从句时，可以互换使用；但在引导主语从句、表语从句和同位语从句以及介词后面的宾语从句或后面紧跟or not时通常只能用whether，而不能用if。

4. 在某些动词后的宾语从句或这些动词的过去分词后的主语从句，以及这些动词的名词形式引导的表语从句和同位语从句中，谓语部分常用“（should）+动词原形”。常见的此类动词有：insist，order，command，suggest，advise，demand，require，request等。

I advised that he_____to the hospital at once， but he insisted that he_____quite well then.

A. be sent； was feeling

B. was sent； felt

C. be sent； feel

D. should be sent； should feel

【解析】 Aadvise后接的宾语从句的谓语动词用“should+动词原形”；insist在句中意为“坚持说……”，其后的宾语从句根据时态一致原则采用一般过去时。

5. whoever，whichever，whatever引导名词性从句与引导让步状从句的区别

Word comes_____free books will be given to_____come first in this book fair.

A. which； no matter who

B. that； anyone who

C. which； whoever

D. that； whoever

【解析】 D“Word comes that ...”意为“消息传来说……”，that引导的同位语从句中含有一个介词后的宾语从句。whoever引导宾语从句，在此相当于“those who ...”，但不能替换为no matter who。

点拨whoever，whichever，whatever可引导名词性从句和让步状语从句。引导名词性从句时，不可由no matter who，no matter which，no matter what替换，因为后者只能引导让步主语从句。值得注意的是whoever引导名词性从句时，通常相当于anyone who或those who；whatever引导名词性从句时相当于anything that。

难点一：连接词多，难以确定

多数名词性从句的连接词都有其特定意思，且在从句中充当句子成分。请参看下表：

注意：that在名词性从句中只起连接作用，不充当句子成分，其本身没有实际意义，在主语从句、表语从句和同位语从句中不能省略，引导宾语从句时可以省略。

点拨解题时应先分析名词性从句意义是否完整，确定应使用有意义的连接词还是无意义的连接词，然后再根据从句所缺成分及连接词的意义确定连接词。

① The media today can draw public attention to

help is actually needed.

A. thatB. which

C. whereD. whose

【解析】 C考查介词后的宾语从句。分析宾语从句句子成分可知，从句是主系表结构，缺少地点状语，故选C。

②All the books I have are here. You may borrow_____you like.

A. whateverB. whichever

C. wheneverD. however

【解析】 B考查宾语从句。从句中缺少宾语，应用连接代词，排除作状语的C和D项。whatever意为“任何……的事物”，不符合题意，也可排除。选择B。

难点二： what考题结构复杂，语义抽象

I lived in_____you call “Ancient Greece” and I used to write about the Olympic Games a long time ago.

A. whatB. which

C. thatD. where

【解析】 Ain后的宾语从句中缺少call的宾语，应用连接代词，排除作地点状语的where；that在宾语从句中不充当句子成分，也不合题意；而which语义不符。

点拨what引导的名词性从句是常考易错点。what除表达具体明确的“所……的东西/事”外，还可以表示“……的时间/地点/人/速度”等抽象意义，难度较大。注意解题时不能仅根据汉语意思选择连接词。

难点三：同位语从句和定语从句的区分

Information has been put forward_____ more middle school graduates will be admitted into universities.

A. whileB. that

C. whenD. which

【解析】 B从句不缺少句子成分，是同位语从句，故选择that作连接词。

点拨同位语从句和定语从句的区别：

同位语从句对名词加以补充说明，是名词内容的体现，且名词和同位语从句的连词均不在从句中充当成分；定语从句对名词加以限制，是名词内容的修饰性定语，且定语从句的关系词在从句中必定充当句子成分。解题时应先分析从句和先行词之间是同位关系还是修饰关系：如果为同位关系则属于同位语从句，如果为修饰关系则是定语从句。

难点四：名词性从句中的插入成分

When you are reading， make a note of_____ you think is of great importance.

A. whichB. that

C. whatD. when

【解析】 C考查名词性从句。介词of后的宾语从句中you think是插入语，从句中缺少主语，故排除D项。which语义不符，而that在从句中不充当句子成分，故选择C项。

点拨有插入语的情况多出现在宾语从句中，常见的插入语有：he thought， you think， I think / suppose / believe等。遇到这种情况时，删除插入语会更容易选出正确答案。
