导语:英语语法是针对英语语言实行研究后,英语语法系统地总结归纳出来的一系列语言规则。英语语法的精髓在于掌握语言的使用。

语法时态。语法:直接引语变间接引语。

直接引用别人的话叫直接引语,用来转述别人的话叫间接引语。例:

he said, "he will go to beijing tomorrow." 直接引语)

he said that he would go to beijing the next day.

直接引语变间接引语时时态、人称及一些时间或个别词都要做相对应的改变。

①时态:一般现在时→一般过去时一般将来时→过去将来时。

现在实行时→过去实行时一般过去时→过去完成时。

现在完成时→过去完成时。

* 但真理性的句子时态不变。例:

he said: "the sun rises in the east."

he said that the sun rises in the east.

他说太阳从东方升起。

②时间:now→then, last month→the month before.

today→ that day, three days ago→three days before.

tonight→that night, tomorrow→the next day.

yesterday→the day before, the day after tomorrow→in two days.

③其它变化:

this→that these→those here→there

come→go

句式的改变:

①直接引语是陈述句加"that"能够省去。例:

he said, "my sister was here three days ago."→

he said that his sister had been there three days before.

②直接引语是一般疑问句,变成用if/whether引导的宾语从句,人称时态等作相对应改变。

mother asked me, "did you buy any meat for lunch?"→

mother asked me if/whether i had bought some meat for lunch.

③直接引语是特殊问句,变成由原来疑问词一样的连接词引导的宾语从句,时态人称等作相对应改变。例:

"what do you do?" he asked me.

he asked me what i did.

④直接引语是选择问句变成由whether或if引导的宾语从句。

"do you like english or chinese?" he asked me.

he asked me whether i liked english or chinese.

语法:被动语态。

1.英语中动词有两种语态:主动语态和被动语态。

主动语态表示主语是谓语动词动作的执行者,被动语态表示主语是谓语动词动作的承受者。

当我们强调谁是某个动作的执行者,即"谁做了某种事情"时,用主动语态。

eg: daniel bought a new computer 丹尼尔买了一台新电脑。(不是别人)

如果主语不是动作的执行者,而是动作的承受者时,就是被动语态。

eg: a new computer was bought by daniel 一台新电脑被丹尼尔买了。

被动语态的谓语由be + 动词的过去分词构成,其中be是助动词,随时态改变。

一般现在时的被动语态由"am / is / are +动词的过去分词"构成。

一般过去时的被动语态由"was / were +动词的过去分词"构成。

2.被动语态的用法:

当不知道或没必要说明动作的执行者时,用被动语态。

eg: rice is grown in south china. 华南种植水稻。(没必要说明是谁种)
