Grammar
宾语从句
在句子中起宾语作用的从句称为宾语从句。宾语从句可以分为三类：that引导的宾语从句、whether/if 引导的宾语从句和疑问词引导的宾语从句。在本单元我们学习 that 和 whether/if 引导的宾语从句。
that引导的宾语从句
I hope (that) you will come to my birthday party.
I believe (that) we shall become good friends.
1. 当谓语动词表示肯定的概念，如“希望”“相信”“知道”或“说”时，其后面的句子一般用that 引导。that没有词义，只具有语法功能，目的是使读者清楚后面的句子是作前面动词的宾语的，多数情况下可以省略。
that引导的宾语从句
I hope (that) you will come to my birthday party.
I believe (that) we shall become good friends.
注：并非所有的动词后面都可一接that 引导的宾语从句。常接 that 引导的宾语从句的谓语动词有 believe, expect, explain, feel, hear, hope, know, imagine, prefer, promise, report, say, see, tell, think, understand, warn, wish 等。
that引导的宾语从句
I’m glad (that) you are coming here on holiday.
I’m sure (that) you'll like it.
2. 主句是“系动词＋形容词”构成的系表结构时，常接that 引导的宾语从句。这类形容词多表示感情，如happy, sorry, afraid, glad, sure 等。
that引导的宾语从句
当主从句之间有插人语时。
It says, on the card, that it is made in China. 卡片上说，它产于中国。
当宾语从句中含有主从复合句时。
I'm afraid that if you've lost it, you must pay for it. 恐怕如果你弄丢了它，你必须赔偿。
3. 引导词 that 用于下列情况时不可省略：
that引导的宾语从句
当宾语从句是双宾语中的直接宾语时。
I can't tell him that his father died.
我不能告诉他他的父亲去世了。
④ 当两个或多个 that 引导的宾语从句由并列连词连接时，除第一个从句中的that 可以省略外，其余从句中的 that 都不可以省略。
He said (that ) the film was very interesting and that he enjoyed seeing it very much.
他说那部电影很有趣，他非常喜欢看。
3. 引导词 that 用于下列情况时不可省略：
whether/if 引导的宾语从句
I want to know whether/if my sister is waiting for me at the school gate.
We don't know whether/if Lucy will be back in two days.
1. whether/if 引导宾语从句时，意为“是否”，表达一个不确定的概念，常放在ask, wonder, know, find out 等词（组）后面。whether/if在从句中不充当句子成分，但不能省略。
whether/if 引导的宾语从句
① 引导的从句作介词的宾语时
I'm thinking about whether we should go to the movies. 我正在考虑我们是否应该去看电影。
2. whether 和 if一般情况下可以互换使用，但在下列情况下只能使用whether，不能使用if。
whether/if 引导的宾语从句
② 直接与 or not 连用时
I'm not sure whether or not his answer is right.我不确定他的答案是否正确。
③后面直接跟带to的不定式时
Mike didn't know whether to go to Australia.
迈克不知道是否要去澳大利亚。
