初中英語語法必考內容

賓語從句

①定義

在句子中起賓語作用的從句叫做賓語從句。

②連接詞

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的情況：

1. 與or not連用：

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

2. 與動詞不定式連用：

He doesn’t know whether to accept the invitation.

3. 連接詞前有介詞時：

It depends on whether he is coming.

③時態

1. 主句是一般現在時態，從句根據實際情況而定(各種時態均可)

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

2.主句是一般過去時態，從句用相應的過去的時態。

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. 如果賓語從句說的是客觀真理、自然現象或事實時，這時賓語從句要用一般現在時態。

The teacher said that the earth goes round the sun.

定語從句

①定義

在復合句中修飾名詞、代詞的從句叫定語從句。

②先行詞

先行詞指人 who /that

先行詞指物 which/ that

定語從句一般緊跟被修飾的名詞或代詞(即先行詞)后

③關系代詞

關系代詞代替先行詞在句子中擔當成分，所以從句中不可再出現其他代替先行詞的代詞

④翻譯方法 “…. 的”

Whom: 先行詞指人，則代替先行詞在定語從句中充當賓語(包括介詞的賓語), 與who的區別是如果前面帶介詞則必須用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，作定語，表示 “…的”

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

關系代詞只能 that 的特殊情況：

1.先行詞前有序數詞修飾時：

This is the first gift that my parents bought me.

2.先行詞前有形容詞最高級修飾時：

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

3. 先行詞是不定代詞something, anything等時.

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