今天讲的是宾语从句需要注意的地方，我只针对高考中经常出现的知识点进行讲解。

1、连词that一般可省略

e.g. I hope (that) everything is all right.

2、连词that在以下几种情况中不能省略

（A）当that从句和主句谓语动词之间有插入语，that不可省略；

He judged that, because he was a child, he did not understand wine.

（B）当that 从句与另一从句并列作宾语时，that不能省；还可以理解为第一个宾语从句that可以省略，第二个宾语从句不能省略；

Everyone knew what happened and that she was worried.

Everyone knows he is a good student and that he gets on well with other fellow students.

（C）当that作介词宾语时，that不可省掉。如：

The reason lies in that she works harder than the others do.

3、whether和if的用法

1）whether和if在宾语从句中可以互换，但是作介词宾语时用whether。如：

It all depends on whether they will come back.

2）后面直接跟or not 时用whether，但是or not和前面分开始，可以用if, 也可以用whether。如：

I didn’t know whether or not he had arrived in Wuhan.

I didn’t know whether he had arrived in Wuhan or not.

I didn’t know if he had arrived in Wuhan or not.

3）whether常与or连用表示一种选择，if不能这样用

The question of whether they are male or female does not matter.

4、形式宾语

在英语中，有些表示“喜怒哀乐”的动词（enjoy, hate, love, like, dislike, appreciate, prefer）后面接when, if 引导的从句作宾语，还有表示大脑思想活动的动词（think, make, find, consider, feel, suppose）后面接宾语补足语时，后面也接宾语从句。

I will appreciate it if you could lend me a hand.

He makes it a rule that he walks for half an hour every day.

5、主句是think, believe, suppose, expect等表示心理活动的单词，如果从句表示否定含义，需要将not否定词转移到主句上

I don’t think you are right.

我想你是不对的。

6、虚拟语气

(1) 在我们总结的歌诀：“一坚持，二命令，三建议，四要求”这些动词的后面跟宾语从句的话，需要用虚拟语气。

My English teacher always suggests that we should read more English materials.

(2) wish后的宾语从句要用虚拟语气。

I wish I could be a pop music composer.
