1、高考英语 语法重难点系列 专题10 名词性从句考点（直击高考）2013高考英语 语法重难点系列 专题10 名词性从句考点 在句子中起名词作用的句子叫名词性从句(Noun Clauses），引导名词性从句的词叫连词。 名词性从句又分别称为: 主语从句、宾语从句、表语从句、同位语从句主语从句：是在复合句中充当主语的从句，常放在谓语动词之前或者用形式主语it代替，将其本身放在句尾。 例如：1. That he came here just now has been proved. 他刚才来的这里得到了证实。 解析：That he came here just now在谓语has been prove

2、d的前面，所以是主语从句。 2. Its true that we are going next week. 我们下星期走是真的。 解析：真正的主语是 that we are going next week，前面的it是形式主语。宾语从句：在复合句中作宾语的名词性从句，通常放在主句谓语动词（及物动词）和介词之后。例如：1. We all know what he is. 我们都知道他是干什么的。 解析：what he is作及物动词know的宾语从句。 2. His worry is about whether he can succeed. 他的担忧是关于他是否能成功。 解析：whether

3、 he can succeed作介词about的宾语从句。表语从句：在复合句中作表语的名词性从句，放在系动词之后，一般结构是：主语+联系动词+表语从句例如：1. His question is where he can buy a house. 他的问题是他能在哪里买房子。 解析：where he can buy a house是联系动词is后面的表语从句。 2. This is why we cant get their support. 这就是我们得不到他们支持的原因。 解析:why we cant get their support是联系动词is后面的表语从句。同位语从句：是用以说明所修

4、饰名词的具体内容的，它与被修饰的词语通常可以划等号。例如：We heard the news that our team had won. 我听说了我们球队获胜的消息。 为了思维的连贯性，此专题我们不以从句的分类来讲，而以连词的分类讲。引导名词性从句的连词主要有以下几类：1.具有词汇意义的连词 （what, how, who, when, where, why,whose, which）2.没有词汇意义的that（that在句中没有如何意义，只起连词的作用）3.if/whether （是否）4.具有双重身份的what5.疑问词+ ever（whatever、whoever、whomever、h

5、owever、whenever、wherever、whichever）一、具有词汇意义的连词 1. I know when he was born. 我知道他什么时候出生的。 2. Where he lives is known to us all. 他住在哪里我们大家都清楚。 3. My question is how you came to school. 我的问题是你怎样来的学校。 4. He told us why she was late. 他告诉我们她为什么迟到。 5. Please let me know what you are . 让我们知道你是干什么的。 6. Which

6、team will win isnt clear. 哪只队将要赢还不清楚。 从上面的例句我们可以看出上述引导名词性从句的连词都具有词汇意义。 二、that的用法1.I know that your name is Tom. （宾语从句） 我知道你名字叫汤姆。2.The news that they won the match excited us very much. （同位语从句）他们获得了比赛胜利的消息使我们都非常兴奋。3.That he often helps my sister makes me happy. （主语从句） 他经常帮我妹妹使得我开心。4.My demand is tha

7、t you (should ) try to study hard. （表语从句）我的要求是你们尽力努力学习。 从上述四个句子我们可以看出that在句中不具有任何词汇意义，也不充当任何成分。一）that引导主语从句常用it作形式主语的情况：（should) do.（因为其动词都是表“建议、命令、要求、主张、决定”等）动词原形的虚拟语气。1）老师建议我们早上早起。 The teacher suggests that we (should) get up early in the morning. (宾语从句）2）我们决定你们下个星期去郊游。 We have decided that you (s

8、hould) go for an outing next week.(宾语从句）3）班长要求我们的家庭作业尽早地交上去。 The monitor demands that our homework (should) be handed in as soon as possible. （宾语从句）3.

18、. 他除了嘴唇在动，一动不动地站在那里。6.宾语从句中that不可省略的使用情况：引导宾语从句中的that 通常可以省略，但是在下列情况下不能省a. 一个动词后面跟有两个或两个以上的宾语从句时 , 最后一个从句前的that不能省 I know (that) you are very clever and that you always work hard. 我知道你很聪明你很用功。b. 当that从句作learn, suggest, explain , agree, prove, mean, feel, state等动词的宾语时 I learn that he has arrived. 我得知

20、道你需要的仅仅是本书。f. 当主句中的谓语动词是固定词组时 He has made up his mind that he will try to catch up with his classmates. 他下决心他将努力赶上他同班同学。7.宾语从句中否定的转移：当主句的主语是第一人称，谓语是think, believe, suppose等表示“意念，信念，揣测”的动词时，宾语从句的否定要提到主句上来，反义疑问句则要根据宾语从句的主谓进行变化。a.

23、 The teacher told us knowledge is power. 老师告诉我们知识就是力量。b. When I was a boy, I knew the earth is round. 当我小的时候我知道地球是圆的。三、if/whether（是否）的用法 四、what：在从句中具有双重身份。即：既引导名词性从句，在名词性从句中 又充当一个成分。 我父母把我培养成我现在的样子。 解析：这里的what相当于the person who/that7. After what seemed five years , he came . After five years，he came.

24、 似乎过了五年之后，他来了。 解析：这里的what相当于the time that8.Finally he went to what is called America. Finally he went to America. 最后他去了叫美国的地方。 解析：这里的what相当于the place that9. I live in what people call Wuhan .

26、nyone who/anyone that，而whomever只作宾语。 2. however 1）不管怎样 However =No matter how you come to school, you must arrive on time. 不管怎样来上学，你都必须准时。2）形容词或者副词要紧跟在后面 a. However hard English is , I want to study it well.= No matter how hard English is, 不管英语多难，我都想学好。 b. However busy he is ,he will come to see me.

27、= No matter how busy he is, 不管他多忙，他都要来看我。 c.

(what） 答案: No matter what 解析：在做这道题时，许多学生的答案可能会是Whatever. 在这里是引导的状语从句，但 由于是要求用括号内的单词完成句子，所以答案

28、就只能是No matter what 2)_ (不管你什么时候方便）, please come to my home .(when) 答案：No matter when it is convenient to you。 解析：在这里就不能是Whenever it is convenient, 理由是括号里给的是when。 七，表语从句的补充：1.This is where he lives. 这就是我住的地方。2.Thats where I first met her. 那就是我第一次遇见她的地方。3.Thats how he studies his lessons. 他就是这样学习功课的。4

29、.Thats why he didnt come. 这就是他没有来的原因。5.This is why he ran so quickly . 这就是他跑得这样快的原因。6.That was when I was fifteen . 这是我15岁的时侯发生的事。根据上面的例句大家注意到了where，how，when，why在引导表语从句时的中文意思。where 的意思是“的地方”、why的意思是“原因”、how的意思是“这样”、 when的意思是“的时候”在这种情况下其句子的主语都是“this”或者“that”，否则他们的词汇意义就会有变。1.My problem is how he can a

30、rrive so early. 我的问题是他怎样能那样早到。 2.His doubt is when they will finish the project. 他的疑问是他们什么时候将完成那项工程。 3.What I want to know is why you always sleep in class. 我想知道的是你为什么上课总睡觉。 4.His question is where he must go. 他的问题是他必须去哪里。八、同位语从句在句中作同位语的名词性从句叫同位语从句.它用以进一步说明与它同位的名词所表示的具体内容。常可带同位语从句的名词有advice,belief,doubt,dream,hope,idea,message, news,order,possibility，promise, problem, question, suggestion, thought, truth, view,wish,word等1.The news that they have won the match is true. 他们获得比赛胜利的消息是真的。 解析：that they have won the match是前面news的内容。2.
