宾语从句
8 )引导宾语从句的连词:that(陈述句作宾语从句由that引导,that无意义,可省去),if/whether(一般疑问句作宾语从句用if或whether引导,意为“是否”)和特殊疑问词(用来引导特殊疑问句所作的宾语从句)。
1.引导词
(1)在以that 引导的宾语从句中,若是that引导陈述句作宾语,that可以省略。如:
The radio says (that) it will rain tomorrow.
收音机报道说明天要下雨。
(2)以连接代词which,what,who等或连接副词how,where,why,when等引导特殊疑问句作宾语的从句,从句改用陈述语序。如:
Could you tell me ______________ to you?
你能告诉我他跟你说了些什么吗?
what he said
Can you tell me __________________________________________?
你能告诉我他从哪里来的吗?
I don’t know ________________________.
我不知道我爸爸什么时候来。
where he is from/ where he comes from
when my father will come
(3)以 whether 或 if 引导一般疑问句或选择疑问句作宾语的从句,从句改用陈述语序。如:
I wonder __________ you have told the news to Li Lei.我想知道你是否已经告诉李雷这个消息了。
如果句中有出现or not 只能用whether 引导
if/whether
2.时态
(1)当主句为一般现在时、现在进行时、或一般将来时时,从句使用相对应的时态。如:
Xiaoming wants to know what time you got up this morning.小明想要知道今天早晨你是几点起床的。
(2)当主句为一般过去时时,从句要用相对应的过去时。如:
We asked what Jean was doing then.
我们问Jean那时正在做什么。
(3)当从句表述的是客观真理或普遍规律时,宾语从句要使用一般现在时。如:
Lisa asked whether light _____________ faster than sound.
丽萨问光的传播速度是否比声速快。
Polly said ___________________.
波利说没有消息就是好消息。
travels/goes
no news is good news
3.语序
(1)陈述句改为宾语从句,语序不变,即仍用陈述语序。
He is a good boy. The teacher said.
→The teacher said (that) he was a good boy.
(2)一般疑问句和特殊疑问句改为宾语从句,语序改为陈述语序。
Does he work hard?I wonder.
→I wonder if/whether ______________.
When did he leave?I don't know.
→I don't know ________________.
he works hard
when he left
[提醒] 宾语从句与简单句的转换
由特殊疑问词引导的宾语从句常可以转换为“特殊疑问词+to do”结构的简单句。
I don't know what I should say.
→I don't know what__________.
to say
2.引导宾语从句的连词:that(陈述句作宾语从句由that引导,that无意义,可省去),if/whether(一般疑问句作宾语从句用if或whether引导,意为“是否”)和特殊疑问词(用来引导特殊疑问句所作的宾语从句)。如:
I want to know ______ you will start.
我想知道你何时出发。

我担心她能否按时来。
