关于“Whether“的用法
回楼主,这句话不能这么改。
当whether作为疑问词来提问的时候,必须放在主语或者形式主语的前面(这里的
whether
可以被
if
完全同意替换,意思是“是否”),表条件或者选择。
例如:
Whether
(if)
it
going
to
rain
tomorrow?
明天是否会下雨?
Wheterh
(if)
England
will
win
the
game?
英格兰能否赢下这场比赛?
whether的用法~~
whether和if的用法分析
whether和if都可以引导宾语从句,表示“是否”,在口语或间接引语中两者可以互换使用。如:
I
wonder
if
/
whether
I
can
get
some
advice
from
you.
Ask
him
whether
/
if
he
can
come.
但在有些情况下,whether和if的用法有一定区别。
1.
whether引导的从句常可以与连词or或or
not直接连用,而if一般不能。如:
正:
Let
me
know
whether
you
can
come
or
not.
误:
Let
me
know
if
you
can
come
or
not.
2.
当宾语从句提到句首时,只能用whether引导,而不能用if。如:
正:
Whether
it
is
true
or
not,
I
can’t
tell.
误:
If
it
is
true
or
not,
I
can’t
tell.
3.
whether可以引导带to的不定式,if则不能。如:
正:
I
don’t
know
whether
to
accept
or
refuse.
误:
I
don’t
know
if
to
accept
or
refuse.
4.
whether及其引导的成分可放于介词之后,作介词的宾语,但if不能。如:
正:
I
worry
about
whether
I
hurt
her
feelings.
误:
I
worry
about
if
I
hurt
her
feelings.
5.
whether可以引导从句,作主语、表语或同位语,而if不能。如:
正:
It
was
uncertain
whether
he
would
come.
误:
It
was
uncertain
if
he
would
come.
正:
His
first

was
whether
Tom

arrived
yet.

His
first
question
was
if

had

讲讲宾语从句whether的用法
通常用 whether 的场合
(1) 引导主语从句且放在句首时。如:
Whether he will come is still a question. 他是否会来还是个问题。
注:若在句首使用形式主语 it,而将主语从句放在句末,则有时也可用 if 来引导。如:
It was not known whether [if] he would come. 不知他是否会来。
(2) 引导表语从句时。如:
The question is whether we should go on with the work. 问题是我们是否应该继续进行这项工作。
注:引导表语从句偶尔也用 if (很不正式),但远不如用 whether 常见。
(3) 引导宾语从句且放在句首时。如:
Whether he is single I don’t know. 他是否单身,我不知道。
(4) 引导让步状语从句时。如:
Whether he agrees or not, I shall do that. 不管他同意与否,我都要那样做。
(5) 与 or 连用分别引导两个从句时。如:
I don’t know whether he is wrong or she is wrong. 我不知道是他错了,还是她错了。
注:or 若不是引导两个从句,而是连接两个词或短语,则也可用 if (但不如用 whether 常见)。如:
He didn’t know if [whether] we should write or phone. 他不知道我们是写信好还是打电话好。
(6) 用于不定式之前时。如:
I’m not sure whether to stay or leave. 我不知是留还是去。
I didn’t know whether to laugh or to cry. 我真是哭笑不得。
(7) 用于介词之后时。如:
It depends on whether the letter arrives in time. 这取决于信是否来得及时。
I worry about whether I hurt her feelings. 我担心是否伤了她的感情。
(8) 直接与 or not 连用时。如:
I will write to you whether or not I can come. 我能不能来,我将写信告诉你。
注:若不是直接与 or not 用在一起,则有时也可用 if。如:
I don’t know whether [if] he will win or not. 我不知他是否能赢。
(9) 在某些动词后(如 discuss 等) 通常只用 whether。如:
We discussed whether we should hold a meeting. 我们讨论了是否要开一个会。
