语法讲解
宾语从句
I. 宾语从句 即在复合句中作主句的（及物动词或介词）宾语。宾语从句通常由连接代词或副词引导；可分为四类：
1．由 that引导的宾语从句（that没有任何意义，在从句中不充当任何成分，在口语和非正式文体中常可以省略）：
I thought （that）the food was rather expensive.
Mother knows (that) Jim will work hard.
2. 由 if /whether“是否” 引导的宾语从句：
I wonder if/whether it was Disney who made the first cartoons.
Could you tell me if/whether Mr. Black lives here?
3. 由 what, why, when, where, who, which, whose, whom, how 等 wh- 类连接代词或副词引导的宾语从句：
Can anyone fail to see what kind of show they are putting on?
Please tell me which class you are in?
He asked me whom I was waiting for.
The stranger doesn’t know when the ship arrives.
I didn’t understand why the boy had so many questions.
Please ask the teacher how we get to the place.
4．由关系代词型what 等代词引导的宾语从句：
We always mean what we say.
I will try to make up what I have missed.
I’ll give you whatever help you need.
I’ll read whichever book you recommend
II.使用宾语从句应注意的几个问题
1．连接代词或副词的使用。连接代词或副词的使用是由句子的意义决定的（这是高考的重点）。
A computer can only do what you have instructed it to do.
--“Doesn’t Helen live on this street?”
--“No. This is where Leon lives.”
2. 宾语从句的语序。无论是连接代词还是连接副词引导的宾语从句的 语序都应是陈述句的语序。
She asked the boys if they had white hats.
I don’t remember when we arrived.
Do you know which class he is in?
3. 时态的呼应。分以下三种情况考虑：
1） 主句的谓语动词是过去时态时，从句的时态也应是过去的某种时态。
He answered (that) he was listening to me.
Lily told us (that) she was born in May, 1980.
2) 主句的谓语动词是过去时态时，从句所叙述的是客观真理、格言时，从句时态无需改变，仍用一般现在时。
The teacher said that (that) the earth goes around the sun.
Father told me that practice makes perfect.
2）主句的谓语动词是现在时或将来时，从句的时态不受限制。根据实情，可使用任何所需时态。
He says he will be back in an hour.
They know Jim is working hard.
4．形容词后的宾语从句。
