第12 讲 宾语从句专题
【学习目标】
【基础知识】
Ⅰ . 定义
1. 宾语从句,顾名思义,是一个用作宾语的句子。例如:
I don’t know if / whether my father will come back tomorrow. (我不知道明天我爸爸是否会回
来。)
Tom can’t decide which sweater he should buy. (汤姆不能决定应该买哪一件羊毛衫。)
We all know(that)the sun rises in the east. (我们都知道太阳在东方升起。)
Ⅱ . 语序
宾语从句必须用陈述句语序
主语十谓语+宾语从句(从句由“连接词+陈述句”构成
Ⅲ . 连接词
1. that 引导宾语从句只起连接作用,其本身没有意义,在口语中常可省略:
主语+谓语+宾语从句(“ that+陈述句”)
I think(that)you should be more careful.我觉得你应多加小心。
I’m afraid(that)he won’t come on time.我恐怕他不会准时到。
2. whether/if 引导宾语从句,意为“是否”:
主语+谓语+宾语从句(“whether+陈述句”)
I wonder whether/ if he will come.
我不知道他是否会来。
【注意】只用 whether 不用 if 的情况
引导介词后的宾语从句时
It depends on whether it will snow tomorrow.
与or not 连用时
I ask your secretary whether she could come or not.
与不定式连接
I really don't know whether to accept or refuse.
④宾语从句前置,置于句首时
Whether they can come here on time,we don’t know.
3. 疑问代词和疑问副词引导宾语从句
疑问代词 who,which,what,whose,whom 以及疑问副词 when,where,how,why 均引导
宾语从句,但一定要注意用陈述句语序。
(1) who/whom: 主语+谓语+宾语从句(“who/whom+陈述句”)
Do you know who/ whom they are? 你知道他们是谁吗?
(2) who: 主语+谓语十宾语从句(“who+陈述句”)
I know who is crying over there.我知道谁在那里哭。
(3) which: 主语+谓语+宾语从句(“which+陈述句”)
Please tell me which bus I should take.请告诉我该做哪一辆公交车。
(4) what: 主语+谓语+宾语从句(“what+陈述句”)
I don’t know what I should do. 我不知道该做什么。
(5) when: 主语+谓语+宾语从句(“when+陈述句”)
Do you know when he will go? 你知道他什么时候走?
(6) where: 主语+谓语+宾语从句(“where+陈述句”)
Can you tell me where he will go? 你能告诉我他要去哪么?
(7) how: 主语+谓语+宾语从句(“how 十陈述句”)
I don’t know how to do it. 我不知道怎么做。
Ⅳ . 时态
1. 当主句的谓语动词时一般过去时时,其宾语从句的时态一般要用相应的过去时态。
The policewoman asked the little boy where he lived.
He said (that)he was going to take care of the baby.
2. 当主句的谓语动词是一般现在时或祈使句时,其宾语从句的时态可以是任何适当的时态。
Please tell me whom you went to the garden with this morning.
3. 当宾语从句表达客观事实或规律时,其时态应用一般现在时。
The teacher said that the earth goes round the sun.
Everyone knew that there are sixty minutes in an hour.
Ⅴ . 直接引语变间接引语
1. 引语是陈述句: 主语+said, “陈述句” => 主语+said+(that)+陈述句
直接引语:He said, “I’m very glad.”
间接引语:He said (that) he was very glad.
2. 引语是一般疑问句: 主语+asked, “一般疑问句 => 主语+asked+ whether/if+陈述句
直接引语:He asked, “Are you very busy these days?”
间接引语:He asked me whether/was very busy those days.
直接引语:He said, “Can you come this afternoon, John?”
间接引语:He asked whether John could go that afternoon.
3. 引语是特殊疑问句: 主语 asked, “特殊疑问句” => 主语+asked+疑问词+陈述句
He said, “When do you want to leave?” => He asked me when I wanted to leave.
He said, “What do you want to read?” => He asked me what I wanted to read.
He said, “Where is Mr. Wang?” =>He asked where Mr. Wang was.
4. 引语是祈使句: 主语+ask/tell/ order sb. (not) to do sth.
He said, “Open the door, John!” =>He asked John to open the door.
He said, “Don't talk in class!” => He ordered us not to talk in class.
