宾语从句
基本结构：___________________________
主+谓+that引导的宾语从句
1. that引导的宾语从句
＊主句的谓语动词是know, believe, think, hope, tell, say, understand, report, wish, promise, see, expect, explain, feel, hear, imagine, prefer, warn等时，常接 that 引导的宾语从句。
3) Bill thinks that the book is interesting.
1) I’m afraid (that) he can’t come．
恐怕他不能来了。
2) I’m so pleased that you will come tomorrow.
我很高兴明天你来。
＊宾语从句也可用于一些描写情感的形容词之后，如：afraid, glad, happy, pleased, sad, sure, sorry等等。
* think, believe, suppose, guess等动词作主句的谓语，且主句的主语是第一人称 I 或we时，宾语从句的否定词not习惯上要转移到主句中，即“否定转移”。
我相信他不会做如此愚蠢的事。
I believe he will not do such a silly thing.
I don’t believe that he will do such a silly thing.
我认为他不会说英语。
I don’t think he can speak English.
I think he can’t speak English.
有些宾语从句不能省略that：
谓语动词后跟有两个或更多个并列的宾语从句，第二个及以后的that都不可以省略。
He said (that) the book was very interesting
and that(不省略) all the children liked to read it.
I think it necessary that he should stay here.
2) 主语中有it作形式宾语，that不可省。

2) He asks whether/if we will go fishing on Sunday.
他问我们是否周日去钓鱼。
if/whether常放在 ask, see, say, know, wonder, find out等动词/词组之后，表达不确定概念，意为“是否”，从句部分的语义相当于一个一般疑问句；whether/if 不可省略，两者常可换用，口语多用if。
2. whether/if 引导的宾语从句
基本结构：_________________________________
主+谓+(宾)+whether/if引导的宾语从句
if或whether引导宾语从句时，作“是否”讲，一般情况下，两者常可换用。
只能用 的情况 Please tell us whether to go or stay here.

not 的固定搭配中
3. 在介词后
4. 宾语从句放在句
首表示强调时

She wonders if/whether she can keep that book for one more week.

2)“Can you help me ” She asks. →

2) Does he work hard I wonder. (合成一句)
3.宾语从句的语序
不论什么情况下，宾语从句都要用陈述语序，即“主语＋谓语＋其他”。

1) He tells me that he’s very busy.
2) He tells me that he was born in 1985.
3) It says that the experiment has been done successfully.
4) I don't know whether we'll go there tomorrow.

主句：一般现在时
当主句是现在时态时，从句可以根据实际情况采用任何时态。
1. It seemed that they were speaking to me in person.
2. We thought somebody was moving about.
3. Lingling's uncle said it was an animal.

他说时间就是生命。
如果从句表达的是客观事实、真理、自然现象、名言、警句、格言、谚语等等，尽管主句用过去时态，从句也要用一般现在时。
