定语从句

1. 定语从句的概念

在复合句中，修饰某一名词或代词的`从句叫定语从句。被修饰的名词或代词叫先行词，引导定语从句的词叫关系词，定语从句一般放在先行词的后面。

2. 定语从句的关系词

引导定语从句的关系词有关系代词和关系副词，常见的关系代词包括that， which， who(宾格whom，所有格whose)等，关系副词包括where， when， why等。关系代词和关系副词放在先行词及定语从句之间起连接作用，同时又作定语从句的重要成分。

3. 定语从句的分类

根据定语从句与先行词的关系，定语从句可分为限制性定语从句及非限制性定语从句。限制性定语从句紧跟先行词，主句与从句不用逗号分开，从句不可省去。非限制性定语从句与主句之间有逗号分开，起补充说明作用，如省去，意思仍完整。

4. 关系代词的用法

(1)that 既可以用于指人，也可以用于指物。在从句中作主语、宾语或表语。作主语时不可省略，作宾语可省略。例如：

Mary likes music that is quiet and gentle.

玛丽喜欢轻柔的音乐。(that作主语)

The coat (that) I put on the desk is blue.

我放在桌子上的那件外套是蓝色的。(that作宾语)

(2)which用于指物，在句中作主语、宾语或表语。作主语不可省略，作宾语可省略。例如：

The film (which) we saw last night was wonderful.

我们昨天晚上看的那部电影很好看。(作宾语)

(3)who， whom用于指人，who 用作主语，whom用作宾语。在口语中，有时可用who代替whom。who和whom作宾语时也可省略。例如：

经常在英语方面帮助我的那个女孩是英国人。(作主语)

Who is the teacher (whom) Li Ming is talking to?

正在与李明谈话的老师是谁?(作宾语)

4. 关系副词的用法

(1)when指时间，其先行词表示时间，when在定语从句中作时间状语。例如：

This was the time when he arrived.

这是他到达的时间。

(2)where指地点，其先行词表示地点，where在定语从句中作地点状语。例如：

状语从句

1. 时间状语从句

(1)时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。例如：

While he was doing his homework, the telephone rang.

As he walked along the lake, he sang happily.

He had learned a little Chinese before he came to China.

After he finished middle school, he went to work in a factory.

(2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如：

I’ll ring you up as soon as I get to New York.

I will tell him everything when he comes back.

He won’t believe it until he sees it with his own eyes.

(3)在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是“一直到……时”，谓语动词只能用延续性动词。如果主句用否定式，其含义是“直到……才……”， “在……以前不……”， 谓语动词可用瞬间动词。例如：

The young man read till the light went out.

Let’s wait until the rain stops.

We won’t start until Bob comes.

Don’t get off until the bus stops.

2. 条件状语从句

(1)条件状语从句通常由if, unless引导。例如：

What shall we do if it snows tomorrow?

Don’t leave the building unless I tell you to.

(2)在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。例如：

I’ll help you with your English if am free tomorrow.

He won’t be late unless he is ill.

(3)“祈使句 + and (or)+ 陈述句” 在意思上相当于一个带有条件状语从句的复合句。例如：

Hurry up, or you’ll be late.

=If you don’t hurry up, you’ll be late.

Study hard and you will pass the exam.

=If you study hard, you will pass the exam.

3. 原因状语从句

He didn’t come to school because he was ill.

As it is raining, we shall not go the zoo.

Since you can’t answer the question, I’ll ask someone else.

(2)because表示直接原因，语气最强。Because引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because。As和since语气较弱，一般用来表示明显的原因。由as和since引导的原因状语从居多放在句首。例如：

------Why aren’t going there?

------Because I don’t want to.

As he has no car, he can’t get there easily.

Since we have no money, we can’t buy it.
