名词性从句讲义1
名词性从句讲义一. 名词性从句在句子中起名词性作用的从句叫做名词性从句(Noun Clauses). 名词性从句在句中的作用相当于名词或名词短语, 在复合句中担当主语, 宾语, 表语和同位语等. 因此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.引导名词性从句的连接词可分为三种:连接词: that, whether, if (不在从句中做任何成分)连接代词: what, who, whom, which, whose和wh+ever (通常在从句中做主语,宾语,表语等) 连接副词: when, where, why, how以及wh/h+ever(通常在从句中做状语)二.主语从句1.概念: 主语从句是在复合句中充当主语的从句.2.连接词:that只起连接主句和从句的作用,在从句中不担任任何成分,本身没有词义,不可省略whether 连接主句和从句, 在从句中不担任任何成分, 但本身有选择或是否的含义whether与if 区别〔一〕引导宾语从句，一般既可用whether 也可用if。
但1 or not放在whether之后时，只能用whether 不用if。
I don’t know whether or not he will come. 我不知道他是不是回来。
注1：如果or not放在whether所引导的从句句尾，那么可以用if来替换。
I don’t know whether/if he will come or not.我不知道他是不是回来。
2 在强调任意选择时,用whether…or,此时不用if替换whether。
He asked me whether I wanted to go there by train or by bus.他问我是想乘火车还是坐公共汽车去那里。
注：whether和or一起还有“不管〞之意,引导让步状语从句。
Whether he drives or takes the train, he will be here on time.不管开车来还是乘火车来，他都会准时到。

名词性从句(1)一、名词性从句1．—What impresses you most when you visit the Acropolis ?— ________ it is that has brought the grand palace into today's terrible scene.A. WhereB. WhatC. HowD. When【答案】 B【解析】【分析】句意：——当你参观雅典卫城时，你印象最深的是什么？——使我印象最深的是什么将从前宏伟的宫殿变成了今天惨不忍睹的样子。
强调句型的特殊疑问句式：疑问词（如what） is it that+其它，本句强调的是什么使得从前宏伟的宫殿蜕变的，所以用表示内容的what，选B【点评】考查主语从句和强调句，本题强调主语从句的引导词。
2．Some people believe _______ has happened before or is happening now will repeat itself in the future.A. whateverB. wheneverC. whereverD. no matter what【答案】 A【解析】【分析】句意：一些人认为之前发生的或现在正在发生的任何事情在将来都会重复发生。
Whatever has happened before or is happening now是一个主语从句，whatever既引导起这个主语从句，也在句中做主语。
BC项都属于副词的性质，都不能做主语，通常只能做状语；no matter what只能用来引导状语从句，故选A。
【点评】考查名词性从句，本题涉及"特殊疑问词+ever"引导的主语从句。
3． is even more important is the earth cooled down, water began to appear on its surface.A. When; that; whenB. What; whether; asC. What; that; asD. lt; whether; as 【答案】 C【解析】【分析】这题考查从句的用法，第一空填what引导主语从句，在主语从句中what做主语，第二空填that引导表语从句，在表语从句中，as是引导时间状语从句，句意是：甚至更重要的是：随着地球的冷却，水开始出现在表面。

二、注意正确使用时态
1. 如果主句是一般现在时、一般将来时或祈使句时，宾 语从句时态不受限制 I hear he is here today/ he was here yesterday/ he will be here tomorrow. 2. 如果主句是一般过去时，宾语从句应与主句保持一致， 即使用过去时态的某种形式。 He said he was watching TV/ he had swept the floor/ he would play football after school. 3. 如果宾语从句所叙述的是客观事实、自然现象、科学 真理等时，从句不受主句限制，用一般现在时。 Everyone answered there are sixty minutes in an hour.

名词性从句1
名词性从句英语从句其实就是三个句型的衍生物。
掌握了三个句型就已经掌握了名词性从句。
名词性从句并不难。
只是在我们过去学过的三种基本句型中出现名词的位置上，根据需要将名词扩大成一个句子，并做小小的改动。
也就是说在一个主系表或主谓宾句型中再套上一个主系表或主谓宾的句子而已。
注意中英文表达上的区别I know the teacherI knowI knowI knowI knowI believe that you know that she found▲由连词that、if、whether引导的名词性从句主语谓语宾语（宾语从句）每个人都知道地球围着太阳运行。
主语状语谓语主语谓语宾语（宾语从句）●Everyone knows连词主语谓语状语从上面的例句可以看出，宾语从句只是将宾语扩大成一个句子，并用连词that 引导。
因为that 没有实际意思，通常可以省略。
主语（主语从句）系表语地球围着太阳运行是一条真理。
主语（主语从句）系表语●形式主语系表语主语（主语从句）●It is a truth同样的一个句子，当把它放在主语的位置时，我们便称其为主语从句。
通常将主语从句放在句子的后面，并用it 代替其原先的位置，叫做形式主语。
在这种情况下，连词that 通常不省。
主语系表语（表语从句）●My idea is我的意思是星期天我们去长城。
从上面的句子可以看出将一个完整的句子置于表语的位置，便称作表语从句。
主语从句、表语从句以及宾语从句在句子中所占的位置是名词的位置，所以称它们为名词性从句。
由连词if、whether 引导的名词性从句也是完整的句子，所不同的是that 在句子中没有实际意思，可以省略，而if、whether 因为有是否的意思，故不可省略。
主谓宾语从句●●I wonder形式主语系表语主语从句注：whether可加or not而if 不能。
有时我们可以将由whether引导的主语从句放在句首，if则不能。
名词性从句(1)
(2)表语从句中的虚拟语气 若主句的主语是 advice,suggestion,order,request, requirement等，表语从句中要用虚拟语气。 My suggestion is that we (should) have a discussion.
四、同位语从句
在复合句中充当同位语的名词性从句称为同 位语从句。它一般跟在某些名词之后，用 以解释说明该名词的具体内容。 I heard the news that our team had won. I have no idea when they will be back and settle down. 1.可以跟同位语从句的名词通常有 news,idea,fact,promise,question,doubt, thought,hope,message,suggestion,word, Possibility等
1.在某些名词如demand，wish,suggestion 等后面的同位语从句要用虚拟语气。 There was a suggestion that Brown should be dropped from the team. 2.Whether可引导同位语从句，但if不可以引 导同位语从句。 The question whether we should call in a specialist was answered by the family doctor.
用it 作形式主语的结构
(1) It is ＋ 名词 ＋ 从句 It is a pity that you didn’t attend the lecture yesterday (2) It is ＋ 形容词 ＋ 从句 It is likely that there will be a snowstorm tomorrow. (3) It ＋ 不及物动词 ＋ 从句 It seems that you object to the plan. It happened that… 碰巧… It appears that… 似乎… (4) It ＋be+ 过去分词 ＋ 从句 It is reported that the professor has already carried out this experiment. 据报道…

名词性从句一．概述：在句子中起名词作用的各种从句统称为名词性从句。

二．名词性从句连接词四．if, whether的区别1.引导主语从句时，如果主语从句放在句首，只能用whether不能用if引导，但是如果用it 做形式主语，而把主语从句放在句末时，也可以用if引导.2.引导宾语从句时常放在动词know, ask, care, wonder之后，if和whether均可。
