初中英语语法必考内容

宾语从句

①定义

在句子中起宾语作用的从句叫做宾语从句。

②连接词

that: I think that you can pass the exam.

Whether/if:I wonder if / whether I can get some advice from you.

Ask him whether / if he can come.

“Wh”: I don’t know what the word means.

I don’t know where he found the book.

只用whether的情况:

1. 与or not连用:

I don’t know whether it’s raining or not.

2. 与动词不定式连用:

He doesn’t know whether to accept the invitation.

3. 连接词前有介词时:

It depends on whether he is coming.

③时态

1. 主句是一般现在时态,从句根据实际情况而定(各种时态均可)

She wants to know what he has done for the exam.

2.主句是一般过去时态,从句用相应的过去的时态。

1)She said that she was a student.

2)She said that she would fly to Japan in a week.

3)She said that she had finished her homework already.

3. 如果宾语从句说的是客观真理、自然现象或事实时,这时宾语从句要用一般现在时态。

The teacher said that the earth goes round the sun.

定语从句

①定义

在复合句中修饰名词、代词的从句叫定语从句。

②先行词

先行词指人 who /that

先行词指物 which/ that

定语从句一般紧跟被修饰的名词或代词(即先行词)后

③关系代词

关系代词代替先行词在句子中担当成分,所以从句中不可再出现其他代替先行词的代词

④翻译方法 “…. 的”

Whom: 先行词指人,则代替先行词在定语从句中充当宾语(包括介词的宾语), 与who的区别是如果前面带介词则必须用whom

1. This is the teacher whomwho we like best.

2. I don’t like the boy to whom you are talking.

Whose : 指人或物,作定语,表示 “…的”

eg: Harry is the boy whose mother is our math teacher.

关系代词只能 that 的特殊情况:

1.先行词前有序数词修饰时:

This is the first gift that my parents bought me.

2.先行词前有形容词最高级修饰时:

This is the most exciting film that I have ever seen.

3. 先行词是不定代词something, anything等时.

e.g. Is there anything that you want in this shop
