1、感谢你来百度 英语聊聊吧， 欢迎以后再来：http:/ 18章 名词性从句一.概念名词性从句共有四种:主语从句,表语从句,宾语从句和同位语从句二.相关知识点精讲1 主语从句：主语从句在整个句子中作主语。(1)不同于其它的连词，它不充当句子的成分，只是单纯的连接词，通常不可以省略。分句置于句首时，that 绝对不可以省略。That the driver could not control his war was obvious.It was obvious that the driver could not control his car.(2)if 不能用在主语从句中，而是用 whetherW
2、hether he left (or not) is unknown(3)当主语从句作主语时，谓语动词一般用第三人称单数，下面这个句型例外。What we need is more time and money.What we need are many more books.2.表语从句：表语从句出现在系动词后，充当表语。The trouble is that we are short of money.Go and get your coat. Its where you left it.(1)引导表语从句除了上述三类词外还有 because, as if/ as though等等The
3、reason (why/for which) is that It/This/That is because(2)连系动词“appear, look, seem”的两个常用句型It seems/appears that.It looks/seems as if/as though(与事实相符用陈述语气，与事实相反用虚拟语气)(3)as 也可以引导表语从句Things are not always as they seem to be3. 宾语从句：及物动词，形容词和介词后加宾语从句作其宾语。(1) 宾语从句时态与主句相呼应，但宾语从句表示的是客观真理或普遍现象除外The teacher tol
4、d us that the earth moves around the sun(2) 连词 whether和 if 可以互换，但注意下列情况连词后紧跟 or not时用 whetherI want to know whether or not they will come.作介词宾语是用 whether引导宾语从句He was interested in whether he saw her there.连接词后直接加不定式，不能用 if只能用 whetherHe doesnt know whether to stay or not.如果宾语从句是否定时，一般用 if引导I care if
5、he will not attend the meeting.(3) 当宾语从句后带宾补时，要用“主语+谓语+it +宾补+that-clause,that 不可省略I think it certain that she will do well in her exam.(4) 当主语是 I, we ，主句用 think, believe, suppose, expect, imagine五个动词时，用否定转移I dont think he will win the game, will he?(5) that在宾语从句常可以省略，但由 and或 but连接两个或多个宾语从句时，仅可以省略第一
6、个连词 thatHe said (that) he had eaten nothing but that he wasnt hungry.(6) 注意区别 if引导的宾语从句和条件状语从句I dont know if he will come.If he comes, Ill let you know.4.同位语从句，在句中作某些名词的同位语，对前面的名词进一步说明。用在下列名词 fact,news,idea,hope,believe,hope,thought,doubt.truth,order,suggestion, word etc.(1)There is no doubt that he
7、 will come.There is doubt whether he will come.Word came that Napoleon would come to inspect them.There is no possibility that.(2)that引导的同位语从句与定语从句的区别：在同位语从句中：that 不可以省略，不作成分;定语从句的关系代词 that在定语从句作成分，作宾语时可以省略We are interested in the news that some foreigners would visit our school.We are interested in
8、 the news that he told us.when, where引导的同位语从句与定语从句的区别：在定语从句中，when, where前有分别表示时间、地点的先行词；而在同位语从句中无此对应关系They have no idea at all where he has gone.(同位语从句)Go and get your coat. Its in the place where you left it.(定语从句)5. 疑问词-ever 既可以引导名词性从句，也可以引导让步状语从句，而 no matter+疑问词只能引导让步状语从句No matter where I go, my
9、heart is towards China.I believer whatever he says. Whatever he says, I will never believe him.who与 whoever 的区别 who是“谁”的意思，表示具有疑问，who 相当于 anyone who“无论谁”Whoever leaves the room last ought to turn off the lights.Can you tell me who that gentleman is?6当名词性从句缺少主语、宾语或表语时，引导词通常用 what，它相当于。另外，有时具有感叹意义 all
10、 that, anything that或 the thing(s) thatWhat we cant get seems better than what we have.Tom thought what a beautiful girl Mary was.7.注意区分 it 作形式主语的主语从句与强调句强调句句型 It is/was+被强调部分+that, 去掉 It is/was, that，句子仍然成立。It is natural that they should have different views. 主语从句It is only lately that he had had a
11、 family himself. 强调句What was it that he wanted? I dont know what it was that he wanted.It was in the hotel where he stayed that we discussed the serious problem8.注意 it 作形式主语的主语从句和 as引导非限制性定语从句引导的不同It is known to all that the earth is round.As is known to all. the earth is round.三.巩固练习1_he does has n

30、从句中作主语）He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。（whom/that 在从句中作宾语）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） 。例如：They rushed over to help the man whose car had broken down. 那人车坏了，大家都跑过去帮忙。Please pass me the book whose （of which） cover is green. 请递给我那本绿皮的书。3）which, that 所代替的先行词是事物的名
31、词或代词，在从句中可作主语、宾语等。例如：A prosperity which / that had never been seen before appears in the countryside.农村出现了前所未有的繁荣。 （which / that 在句中作宾语）The package （which / that）you are carrying is about to come unwrapped. 你拿的包快散了。 （which / that 在句中作宾语）2.关系副词引导的定语从句 关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。1）关系副词 when, wher
32、e, why的含义相当于“介词+ which“结构，因此常常和“介词+ which“结构交替使用。例如：There are occasions when （on which） one must yield. 任何人都有不得不屈服的时候。Beijing is the place where（in which） I was born. 北京是我的出生地。Is this the reason why （for which） he refused our offer? 这就是他拒绝我们帮助他的理由吗？2）that 代替关系副词，可以用于表示时间、地点、方式、理由的名词后取代 when, where,
33、why和“介词+ which“引导的定语从句，在口语中 that常被省略。例如：His father died the year （that / when / in which） he was born. 他父亲在他出生那年逝世了。He is unlikely to find the place （that / where / in which） he lived forty years ago. 他不大可能找到他四十年前居住过的地方。3.判断关系代词与关系副词 方法一： 用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词
34、。例如：This is the mountain village where I stayed last year. 这是我去年呆过的山村。Ill never forget the days when I worked together with you.我永远不会忘记与你共事的日子。习惯上总把表地点或时间的名词与关系副词 where, when联系在一起。此两题错在关系词的误用上。方法二： 准确判断先行词在定语从句中的成分（主、谓、宾、定、状） ，也能正确选择出关系代词/关系副词。关系词的选择依据在从句中所做的成分，先行词在从句中做主、定、宾语时，选择关系代词（who, whom, that
35、, which, whose） ； 先行词在从句中做状语时，应选择关系副词 （ where 地点状语，when 时间状语，why 原因状语） 。4.限制性和非限制性定语从句 1） 定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开。例如：This is the house which we bought last month. 这是我们上个月买的那幢房子。（限制性）The house, which we bought last month, is very n
36、ice.这幢房子很漂亮，是我们上个月买的。 （非限制性）2） 当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的。例如：Charles Smith, who was my former teacher, retired last year. 查理史密斯去年退休了，他曾经是我的老师。My house, which I bought last year, has got a lovely garden. 我去年买的的那幢房子带着个漂亮的花园。This novel, which I have read three times, is very touching. 这本小说
37、很动人，我已经读了三遍。3） 非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数。例如：He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思，这使我心烦。Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。说明：关系代词 that和关系副词 why不能引导非限制性定语从句。5.介词+关系词 1）介词后面的关系词不能省略。2）that 前不能有介词。3）某
38、些在从句中充当时间，地点或原因状语的“介词+关系词“结构可以同关系副词 when 和 where 互换。例如：This is the house in which I lived two years ago. 这是我两年前住过的房子。This is the house where I lived two years ago.Do you remember the day on which you joined our club? 还记得你加入我们俱乐部的那一天吗？Do you remember the day when you joined our club?6.as, which 非限定性定
39、语从句 由 as, which 引导的非限定性定语从句， as和 which可代整个主句，相当于 and this或 and that。As 一般放在句首，which 在句中。例如：As we know, smoking is harmful to ones health. 如我们所知，吸烟有害健康。The sun heats the earth, which is very important to us. 太阳使地球暖起来，这对我们人类很重要。as 和 which在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。但不同之处主要有两点：（1）
40、as 引导的定语从句可置于句首，而 which不可。（2） as 代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词；若为行为动词，则从句中的关系代词只能用 which.。7.先行词和关系词二合一 1） Whoever spits in public will be punished here. （Whoever 可以用 anyone who 代替）2） The parents will use what they have to send their son to technical school.（what 可以用 all that代替）8. what/whatever; th
41、at/what; who/whoever 1）what = the thing which；whatever = anything。例如：What you want has been sent here. 你要的动词都送来了。Whatever you want makes no difference to me. 不管你要什么，跟我没什么关系。2） who= the person that whoever= anyone who。例如：3） that 和 what 当 that引导定语从句时，通常用作关系代词，而引导名词性从句时，是个不充当任何成分的连接词。宾语从句和表语从句中的 that常可
42、省略。What 只能引导名词性从句，用作连接代词，作从句的具体成分，且不能省略。例如：I think（that）you will like the stamps. 我想你会喜欢这些邮票的。What we need is more practice. 我们需要的是更多的实践。9.关系代词 that 的用法 1）不用 that的情况a） 引导非限定性定语从句时。例如：（错）The tree, that is four hundred years old, is very famous here.b） 介词后不能用。例如：We depend on the land from which we get
43、 our food. 我们依赖土地获得食物。We depend on the land that/which we get our food from.2） 只能用 that作为定语从句的关系代词的情况a） 在 there be 句型中，只用 that，不用 which。b） 在不定代词，如：anything, nothing, the one, all, much, few, any, little等作先行词时，只用 that，不用 which。c） 先行词有 the only, the very修饰时，只用 that。 d） 先行词为序数词、数词、形容词最高级时，只用 that。.e） 先
44、行词既有人，又有物时。例如：All that is needed is a supply of oil. 所需的只是供油问题。Finally, the thief handed everything that he had stolen to the police. 那贼最终把偷的全部东西交给了警察。三.巩固练习1.
