从句

1.宾语从句

在复合句中，由一个句子充当宾语，这个句子叫做宾语从句。宾语从句主要有三种类型，分别是that引导的宾语从句、if或whether引导的宾从、连接代词和连接副词引导的宾语从句。 常见的宾语从句引导词：that、if、whether、what、who、where、why和how。

Eg. I am sad that you refused me. 我很难过你拒绝了我。

2.定语从句

定语从句在中考和高考中出现的频率都非常高。在复合句中，修饰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。定语从句一般放在先行词的后面。常见的关系代词包括that,which,who(宾格whom，所有格whose),as 等，关系副词包括where,when,why等。

Eg. Lily likes music that is quiet and gentle. 玛丽喜欢轻柔的音乐。

3.状语从句

状语从句就是由一个句子在复合句中充当状语。所以状语从句又可以分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句等等。每种状语从句都有特定的引导词：

(1)地点状语从句：where,wherever

(2)时间状语从句：when, while, as, before, until, till, since

(3)原因状语从句：because, since,as, now that, not that…, but that…, seeing that,

considering that, in that

(4)目的状语从句：so, so that, in order that, that, to the end that, in case,for fear that,lest

(5)结果状语从句：so...that, such that, so that, with the result that

(6)条件状语从句：if,unless,if only,only if,in case,suppose/supposing

(that),provided/providing(that),on condition that,so/as long as

一. 定义：

由to+动词原形构成。不定式是一种非限定性动词。而非限定动词是指那些在句中不能单独充当谓语的动词，可分为不定式，动名词，现在分词和过去分词。“动词不定式”由动词+不定式构成。动词不定式在句中可以作句子除谓语之外的任何句子成分。动词不定式的被动形式除了一般形式外还有其完成式和进行式。

二. 动词不定式的构成：to+动词原形

(1)作主语

动词不定式作主语时，句子的谓语动词常用单数，其位置有以下两种： (1)把不定式置于句首。

如：To get there by bike will take us half an hour.

(2)用it作形式主语，把真正的主语不定式置于句后，常用于下列句式中。

如：

It+be+名词+to do It's our duty to take good care of the old.

It takes sb+some time+to do How long did it take you to finish the work?

It+be+形容词+for sb+to do It is difficult for us to finish writing the composition in a quarter of an hour.

It+be+形容词+of sb+to do It is stupid of you to write down everything (that) the teacher says.

It seems(appears)+形容词+to do It seemed impossible to save money.

在句型中，常用表示客观情况的形容词，如：difficult，easy，hard，important，impossible，necessary 等;

在句型中，常用careless，clever，good，foolish，honest，kind，lazy，nice，right，silly，stupid，wise等 表示赞扬或批评的词。

在不定式前的sb，可看作其逻辑主语。这一句式有时相当于Sb is+形容词+to do句式 ，如：It's kind of you to help me with my English.=You are kind to helpme with my English.

(3)举例

(1) It's easy (for me) to do that.我做这事太容易了

easy,　difficult,　hard,　important,　possible,　impossible,　comfortable,　necessary,　better;

the first,　the next,　the last,　the best,　too much,　too little,　not enough

1、It's so nice to hear your voice.

听到你的声音真高兴。

2、It's necessary for you to lock the car when you do not use it.

当你不用车的时候，锁车是有必要的。

(2) It's very kind of him to help us.　他帮助我们，他真好。

Kind,　nice,　stupid,　rude,　clever,　foolish,　thoughtful,　thoughtless,　brave,　considerate(考虑周到的),　silly,　selfish(自私的)

例句:

1、It was silly of us to believe him.　我们真愚蠢，竟然相信了他。

2、It seemed selfish of him not to give them anything.　他不给他们任何东西，这显得太自私了。

注意：

(1) 其他系动词如，look，appear等也可用于此句型

(2) 不定式作为句子成分时，动词用单数形式。

(3) 当不定式作主语的句子中又有一个不定式作表语时，不能用It is… to…的句型

(对)To see is to believe.　眼见为实。

(错)It is to believe to see.
