2、要注意区分判断由if、when引导的从句类型.

3、　 连接代词who, whom, whose, what, which，连接副词when, where, why, how， 它们起连接作用，作句子成分，各有自己的意义。

eg. The teacher asked the new students which class he was in.

　 I wonder where he got so much money.

[注意]1、由连接代、副词引导的宾语从句可以和“疑问词+不定式”结构转化。

eg. I don’t know how I should do with the presents. è I don’t know how to do with the presents.

2、　 连词if 、whether，它们起连接作用，在从句中不作句子成分，作“是否”解，在口语中多用if。

eg. Tom don’t know if/whether his grandpa liked the present.

　 He asked me whether or not I was coming.

一般情况下，if 和whether可以互换，但以下3种情况只能用whether：

　 ①在不定式前：Whether to go there or not hasn’t been decided.

②在介词前：It depends on(依靠) whether it is going to rain.

③与or not连用：They are talking about whether to go there or not.

1、　 连词that，只起连接作用，在从句中不作句子成分，也无词汇意义，在口语中常被省略。

eg. He knew (that) he should work hard.

5. My sister said,“The earth travels round the sun.”

　 My sister said that ______________________________.

4. She said,“Come at five o’clock.”
