语法是语言学的一个分支，研究按确定用法来运用的"词类"、"词"的曲折变化或表示相互关系的其他手段以及词在句中的功能和关系。下面是小编给大家整理的初中英语语法，供大家参阅!

初中英语语法：some和any的用法

初中英语语法：动词不定式

动词不定式可以作以上各种成分，但它毕竟是动词，所以有动词的属性。

动词不定式及其短语还可以有自己的宾语、状语，虽然动词不定式在语法上没有表面上的直接主语，但它表达的意义是动作，这一动作一定由使动者发出。这一使动者我们称之为 逻辑主语，其形式如下：

(1)语态

如果动词不定式的逻辑主语是这个不定式所表示的动作的承受者，不定式一般要用被动语态形式。如：

It's a great honour to be invited to Mary's birthday party.(不定式作主语是被动语态to be invited是被邀请)

It was impossible for lost time to be made up.(不定式作主语)

I wish to be sent to work in the country.(不定式作宾语)

Can you tell me which is the car to be repaired?(不定式作定语)

He went to the hospital to be examined.(不定式作状语)

在There be结构中，修饰主语的不定式可用被动，也可用主动。如：There are still many things to take care of (to be taken care of).但有时两种形式表达的意思不同，如：There is nothing to do now.( We have nothing to do now.) There is nothing to be done now.(We can do nothing now.)

(2)时态

1) 现在时：一般现在时表示的动词，有时与谓语动词表示的动作同时发生，有时发生在谓语动词的动作之后。

He seems to know this.

I hope to see you again. = I hope that I'll see you again. 我希望再见到你。

2) 完成时：表示的动作发生在谓语动词表示的动作之前。

I'm sorry to have given you so much trouble.

He seems to have caught a cold.

3) 进行时：表示动作正在进行，与谓语动词表示的动作同时发生。

He seems to be eating something.

4) 完成进行时：

She is known to have been wreaking on the problem for many years.

一般在情绪后加to do to do 也表将来

编辑本段疑问词+不定式结构疑问词who,what,which,when,where,whether,how后可接不定式构成不定式短语，在句中作主语、宾语、表 语等。如：

①When to leave for London has not been decided yet. (不定式在句子中做主语)

②Mr. Smith didn't know whether to leave or stay there. (不定式在句子中做宾语)

③I asked Professor Xu how to learn English well. (不定式在句子中做直接宾语)

④The question was where to get the medicine needed. (不定式在句子中表语)

以上例句中疑问词+不定式部分，均可转换为相应的从句形式。如：①When we shall leave…③…how I

could learn…

经常在这种结构中使用的动词有：consider,decide,discover,explain,find out,forget,hear,know,lea rn,observe,understand,wonder等。

编辑本段语法功能一、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：

①It+be+名词+to do

It's our duty to take good care of the old.

②It takes sb+some time+to do

How long did it take you to finish the work?

③It+be+形容词+for sb+to do

It is difficult for us to finish writing the composition in a quarter of an h

It is stupid of you to write down everything (that) the teacher says.

④It seems(appears)+形容词+to do

It seemed impossible to save money.

在句型③中，常用表示客观情况的形容词，如：difficult,easy,hard,important,impossible,necessary 等;在句型④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

It's so nice to hear your voice.

听到你的声音真高兴。

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:

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

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.
