英语名词性从句用法系统归纳

一、句子的种类

英语句子分为三种类型：简单句( Simple Sentence )、并列句( Compound Sentence )和复合句( Complex Sentence )。简单句只有一个谓语，并列句有两个（以上）谓语并且各所代表的部分在句中的地位同等重要，复合句有两个（以上）谓语但是各所代表的部分在句中的地位并非同等重要。

试分析：

1) My head aches. （简单句）

2) We fished all day, but we didn’t catch a thing. （并列句）

3) The alarm was raised as soon as the fire was discovered. （复合句）

二、从句的种类

复合句的各个组成部分在句中的地位不是同等重要的，其中，相对重要的部分是主句( Main Clause )而相对次要的部分是从句( Subordinate Clause )。从句分为三种类型：

⑴副词从句( Adverbial Clause )，即状语从句，在整个复合句中相当于副词的作用；

⑵名词从句( Noun Clause )，包括主语从句( Subject Clause )、宾语从句( Object Clause )、表语从句( Predicative Clause )和同位语从句( Appositive Clause )，在整个复合句中都相当于名词的作用；

⑶形容词从句( Attributive Clause )，即定语从句，在整个复合句中相当于形容词的作用。

三、主句和从句的区分

可以按照以下步骤进行主句和从句的区分：

⑴找出所有谓语；

⑵找出所有连接主句和从句的连词；

例如：

1.从句是由关联词和从属连词引导的,从句的结构是关联词/从属连词+主语+谓语+其他成分. 主句是主语+谓语+其他成分.

I don't konw the place where he lives'

where是从属连词,where he lives 是状语从句.i don't konw the place 是主句.

②After _____seemed a very long time，I opened my eye and found myself in bed.

A.what

B.when

C.that

D.which

(what相当于“the time that”，表示“……时间”)

③He is not what he was a few years ago. Who is it that has made Fred what he is now? (what表示“……的人”，相当于“the person that…”)

④What is now the North Sahara Desert was once a civilized world.

(what表示“……的地方”，相当于“the place that…”)

⑤Our income is now double what it was ten years ago

(what表示“……的数目”，相当于“the amount /number that…”)

名词性从句用法详解

名词性从句用法详解一、概说名词性从句，即指性质相当于名词的从句，它包括主语从句、宾语从句、表语从句和同位语从句。从高考的考查的实际情况来看，名词性从句考得最多的是宾语从句，其次是主语从句，再次是表语从句，而同位语从句则很少考查。二、名词性从句的一般引导词 1. 连接词that 只起连接作用，没有任何意思，也不充当句子成分，在宾语从句中可省略，但引导其他名词性从句时通常不省略。如： I hope (that) you enjoy your holiday. 希望你假期过得好。 That he likes you is very obvious. 很显然他喜欢你。 2. 连接词whether 也不充当句子成分，但有自己的意思，表示“是否”；引导宾语从句时，可换成if，但引导其他名词性从句时不能换成if。如： He asked whether [if] I would show him the way. 他问我是否可以给他带路。 Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。(引导主语从句，不能用if 代替whether) 3. 连接代词who(m), whose, which, what 等，均有各自的意义，在从句中作主语、宾语、定语等。如： That’s why she wanted to leave. 这就是她想离开的原因。 When we arrive doesn't matter. 什么时候到没有关系。 Tell me which one you like best. 告诉我你最喜欢哪一个。 4. 连接副词when, where, why, how 等，也各自有自己的意义，在从句中作状语。如： The question is how we should carry out the plan. 问题是怎样执行这个计划。 When she’ll be back depends much on the weather. 她什么时候回来在很大程度上要看天气。 Why he did it will remain a puzzle forever. 他为什么这样做将永远是一个谜。三、名词性从句的重要引导词 1. what 用于引导名词性从句是一个十分重要的引导词，它可引导主语从句、宾语从句和表语从句，但不用于引导同位语从句。它引导的名词性从句有两个意思是：一是表示“什么”，带有疑问意味；二是表示“…所…的”，相当于一个先行词后接一个关系代词。如： I don’t know what you want. 我不知道你想要什么。 I don’t know what you want is this. 我不知道你所想要的是这个。 2. what 引导名词性从句时可用作限定词，其后修饰名词。如： I gave him what books I had. 我把我所有的书都给他了。 He gave me what money he had about him. 他把身边带有的钱全给了我。注：what 后的名词可以是复数名词或不可数名词，但通常不能是单数可数名词，并且后接不可数名词时，有时可有little修饰，两者的区别是：what+不可数名词=所有的都，what little+不可数名词=虽少但全部。如：

高中英语名词性从句 which的用法

一、在名词从句中连接词which 有两种词性, 常用来引导宾语从句： 1. [连接代词] 哪个 1）用作从句的主语，如： He wanted to know which was on the table. 他想知道哪一个在桌子上。 2) 用作从句的宾语，如： He asked me which I liked best. 他问我最喜欢哪一个。 2. [连接形容词]放在名词前作定语，表示“哪个XX，哪些XX”，如： Do you wnow Which country is the largest? 你知道哪国家一个最大? Could tell me which children made him still more angry. 能告诉我那些孩子使他更加生气了。二、which 除引导上述宾语从句外，还可以引导主语从句和表语从句。 1. 主语从句(常用形式主语it) It was clear which children made him still more angry. 显而易见那些孩子使他更加生气了。 It is known to us which he liked best. 众所周知他最喜欢哪一个。 2. 表语从句 That was which children made him still more angry. 那就是那些孩子使他更加生气了。 This is which he liked best. 这就是他最喜欢哪一个。三、which 与what 的区别用在名词从句中，which 意思是“哪一个/那一些”，what 意思是“所...的”，后者等于“先行词+关系代词”，如你的补充问题就需要选择what： It's quite different from what I read last month. = It's quite different from (the one that) I read last month. 这本书与我上周所读过的那一本区别很大。 1.that在所有名词性从句中无成分无意义。 2.which强调哪一个，有一个选择的范围。从句中from后边缺宾语，所以要选择的是宾语从句的引导词，首先that引导宾语从句时，不做介词宾语（除了in,except,but) 其次read后边缺宾语，也就是从句中缺成分，参见上面第一条，所以排除that.B选项which指哪一个，这里
