主语从句、表语从句、宾语从句、同位语从句，在整个句子中所起的作用，相当于一个名词因此，这四种从句通称为名词性从句。引导名词性从句的连接词可分为三类：连接词that，whether, if （不充当从句的任何成分）连接代词：what, whatever, who, whoever, whom, whose, which,连接副词：when, where, how, why, wh- ever
名词性从句连接词的选用
一、that 和what的选用：
that 和what都可引导所有的名词从句。但是，what除起连接作用外，还在名词性从句中充当成分，可做从句的主语、宾语、或表语。而that在名词性从句中不充当任何成分，只起连接作用。
二、if 和whether 的选用
不能使用if 的情况：
a. 主语从句句首
b. 表语从句，同位语从句
c. if引起歧义
d. 介词后的宾语从句
e. 与to do连用 f .whether or not 连在一起引导宾语从句时不用if
三、其它连接代词和副词的连用
主要根据名词性从句中的具体意义,正确的选择who、which、when、where、why、how 等连接词，这些连接词既具有疑问含义，又起连接作用，同时在从句中充当各种成分。
四、引导词that 的省略
that 可省略的情况：单个宾语从句中的that可省略
that不可省略的情况：a.主语从句b.表语从句c.同位语从句d.用it做形式宾语的宾语从句e.并列的宾语从句中，后几个从句的引导词that 不能省略
五、同位语从句的引导和辨别
1.同位语从句的格式：n.+ 连接词+ 从句
2.能接同位语从句的名词有：fact、idea, news, information, order, belief, suggestion, advice等.
3.连接词通常是that,也可根据含义选用whether, what, when, where 等来引导同位语从句.
4.中心词是“意见、建议、命令”从句要用虚拟（should）do
六、同位语从句和定语从句的区别
1.定语从句是先行词的修饰语。从句中that充当成分，做宾语时可省略。
2.同位语从句表明中心词的具体内容。that 在同位语从句中不做任何成分,只起连接作用,无具体含义,且不可省略.
判断从句类型
七、宾语从句的时态呼应
1. 如果主句时态是现在时或将来时,从句谓语可根据句意需要而选用任一种时态.
2. 如果主句时态是过去式，从句要改成相应的过去式
八、it做形式主语
常用句型如下：（1）It + be + 名词+ that从句（2）It + be + 形容词+ that从句
（3）It + be + 动词的过去分词+ that从句（4）It + 不及物动词+ that 从句

表语从句讲解及专项练习概念：表语从句是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+系动词+表语从句” 可以接表语从句的连系动词有be, look, remain, seem等。 ★ The trouble is that we are short of money.困难是我们资金短缺。 ★ That is why stone walls are used instead of fences around New England fields.这就是为什么在新英格兰用石头墙而不用栅栏的原因。 ★ At that time, it seemed as if I couldn't think of the right word anyhow.当时,我似乎怎么也想不出一个恰当的字眼来。 引导表语从句的词： 从属连词that、whether、as though、 as if（That引导表语从句时，在口语中，间或可以省略。） 关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等； 关系副词when, where, why, how, however, whenever, wherever等。 ※ 由从属连词that，whether引导的表语从句。 that在引导表语从句时无词义，而whether有词义，意为、“是否”。这时主句的
主语常常是些抽象名词，如question(问题)，trouble(麻烦)，problem(问题)，result(结果)，chance(可能性)，suggestion(建议)，idea(想法)，reason(理由)等。表语从句对主句主语进行说明、解释，使主语的内容具体化。 例如： ★ The trouble is (that) she has lost his money. 麻烦的事是他丢了钱。 ★ The question is whether we need more ice cream.问题是我们是否还需要一些冰淇淋。 ★ The problem was that it was too valuable for everyday use.问题是它作为日常之用太贵重了。 ★ What she couldn’t understand was that fewer and fewer students showed interest in her lessons. 我们不能理解越来越少的学生对他的课不感兴趣。 ※ 由关系代词引导的表语从句。 关系代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等引导表语从句，在句中作主语、宾语、表语，关系代词不能省略。 例如： ★ The question is which of us should go.问题是我们哪一个应该去。 ★ The problem was who could do the work.问题是谁能做这项工作。

01 有关概念 由一个主句和一个或一个以上从句构成的句子叫做复合句。所谓主句，就是在复合句中起统领作用 的句子，它是全句的主体，通常可以独立存在；而从句则是复合句的一个句子成分，不能独立存在。 如： You’ll feel better after you take the pills. 吃完药丸后你会感到好一些。 The police learned that he wasn’t there at that time. 警察获知他那时不在场。 这两句都是复合句，第一句的主句是You’ll feel better，从句是after you take the pills，由after 引导，在整个复合句中用作状语，表示时间；第二句的主句是The police learned是主句，that he wasn’t there at that time是从句，由that引导，在整个复合句中用作宾语。 注意，英语的复合句不是简单句的反面，不要将它误解为“复杂句”。事实上，英语的简单句有时 也可以比较“复杂”，而复合句也可以比较“简单”。如： He stopped because he was tired. 他停下来是因为他累了。 这个句子比较“简单”，却是一个典型的复合句，其中的he stopped是主句，because he was tired 是从句，在复合句中用作状语，表示原因。 02 从句的分类 前面我们说到从句是整个复合句的一个句子成分，它可以用作主语、宾语、定语、状语等。一般说 来，一个从句在复合句充当什么成分我们就叫它为什么从句——从句在复合句用作主语，我们就叫 它为主语从句；从句在复合句用作宾语，我们就叫它为宾语从句；从句在复合句用作状语，我们就 叫它为状语从句；等等。 如： He answered that he knew nothing about it. 他回答说他不知情。 The trouble is that I have lost his address. 麻烦的是我把他的地址丢了。 He was rather pleased when he won that prize. 他获奖后相当高兴。 She was not in the train that arrived just now. 她不在刚到的那列车上。
高中状语从句讲解+练习 状语通常由副词、介词短语、动词不定式、分词和从句等担当。例如： 1. Naturally , our grandparents were pleased to get our phone call . (副词) 2. We worked hard , from sunrise to sunset . (介词状短语) 3. To help my disabled aunt , I spend an hour working in her house every day . (不定式) 4. Seen from a distance , the farmhouse looked deserted . (过去分词) 5. I know how to light a camp fire because I had done it before .（原因状语从句） 状语从句主要用来修饰主句或主句的谓语。一般可分为九大类，尽管种类较多，但由于状语从句与汉语结构和用法相似，所以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词和特殊的连接词即考点。现分别列举如下: 1．时间状语从句 常用引导词：when, as, while, as soon as, while, before, after, since , till, until 特殊引导词：the minute, the moment, the second, the instant, immediately , directly, every time, the day，no sooner …than, hardly …when, scarcely …when （1）Tell him I need to see him the minute he arrives. 他一到就告诉他我要见他。 （2）The children ran away from the orchard(果园) the moment they saw the guard.

She was standing exactly where you are standing now那时他就站在你现在站的地方。 Stay where you are.呆在原地别动。 Wherever you go, you should work hard. Sit anywhere you like 随便坐吧 3．原因状语从句
