语法探究
英语中,在复合句中作宾语的句子叫作宾语从句。请注意以下问题:
1.
宾语从句由连接代词或连接副词来引导
(1)that
引导宾语从句时,在句子中不充当任何成分,在口语和非正式文体中常被
________
。例如:
They said they had been there before.
他们说他们以前去过那儿。

省略
(2)
如果宾语从句是
_________
,则由
if/whether
引导。例如:
I don't know if/whether they will come here.
我不知道他们是否会来这儿。
本句是由“
I don't know.”
和“
Will they come here
?”合并而成, 后一句是一般疑问句,作从句时语序要发生变化, 应变为
________(
语序
)
。此时需用
if
或
whether
来引导宾语从句。
注意: ①
if
和
whether
作“是否”讲时,用于引导宾语从句,常放在动词
know, ask, care, wonder, find out
等词或短语之后,介词后

②少数动词,如:

后的宾语从句常用

③whether
后可以加
or not
,但是
if
不可以。
④在不定式前只能用
whether
。例如:
I can't decide whether to stay.
我不能决定是否留下。
(3)
如果宾语从句是

,则由特殊疑问词
what, how, which, when, where, why
