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。

5. “疑问词+ever” whatever, whichever, whoever, whomever 引导宾语从句 I’ll show you whatever you want to see. He likes to makes friends with whoever shares his interest.
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.
• 2.引导主语从句的词： • 连词：that, whether
起连接作用不充当成分
• 连接代词：what(ever),who(ever), which(ever)，whose,
充当主语/宾语/定语等
• 连接副词：when, where, how ,why
充当状语表时间、地点、方式、原因
连接副词：when, where, how ,why引导的主语从句
1.I hear (that)___________.(一小时后会回来)
2.He said (that)___________.(他非常想我们) 3.The teacher told us (that)_____________. (地球围绕太阳转）

That; whatB. That; thatC. What; thatD. What; what【答案】 A【解析】【分析】句意：众说周知，礼貌在每一个国家中都是非常重要的，但是麻烦是，不同的国家对于什么是良好的礼貌有着不同的认识。
逗号前有两个谓语动词，一个是are，一个是is known，故是两句话，需填连词连接这两句话，根据句意可知，前面是主语从句，故填that，此处的that，只起连接作用不作任何成分。
about是介词，其后是个句子故应填连词把这两句话连接起来，所缺词作are的表语，故填what。
因此选A。

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。

(4)当主语为suggestion, order, requirement， request，demand等这类名词时。表语从句的 谓语动词为(should) do，其中should可以省略。

他的建议是你应该戒烟。
experience.
问题是我没有多少经验。

医生建议他应该戒酒。
(3)在动词believe, expect, suppose, think等后 接宾语从句时, 有时宾语从句中的谓语虽然含有否 定意思，但不能用否定形式，要将其否定转移到 主句的谓语动词。(注意:主语为第一人称才转移)

恐怕今天晚上我不能同你去参加晚会了。
(6)还有“介词+宾语从句”的结构。 l don’t agree with what you’ve said． 我不同意你所说的话。

4．同位语从句 同位语从句跟在名词后面，进一步说明该名
词的具体内容，可跟同位语从句的名词主要有 fact, news, promise, idea, truth等。连接词用 that, 不用which。
引导表语从句的关联词除了as if, as though, because外, 其余与引导主语从句的关联词一样， 其具体用法如下：

据报道地震中没有人死亡。 2．宾语从句
置于动词、介词等词后面起宾语作用的从句叫
作宾语从句。宾语从句的语序必须是陈述语序。 谓语动词、介词、动词不定式、v-ing形式后都 能带宾语从句，有些形容词(afraid，sure，glad 等)之后也可以带宾语从句。具体用法如下：
(1)关联词that引导宾语从句，没有实际意义，而 只起连接的作用，即在宾语从句中不充当任何成 分，在口语中常省略。
