从句(真正宾语)
的句型中不省略。

不省略。

told
me（
that）he
would
come
and
that
he
would
come
on
time.

c.当that作介词
except,
in等宾语时。
?They
believe
in
that
she
must
still
be
single.
?I
know
nothing
about
him
except
that
he
is
living
in
Beijing.
2.由从属连词
whether,
if
引导的宾语从句。
?I
want
to
know
if/whether
she
is
right
.
?They
didn’t
know
whether
Tom
could
come
back
or
not
.
if/whether
引导宾语从句
表示“是否”。
if/whether可互换，但whether…or
not为固定搭配。
1).whether和if都可以引导宾语从句
?I
don’t
know
whether
or
not
he
will
come.
如果or
not放在whether所引导的从句句尾，可用if
替换。
?I
don’t
know
whether/if
he
will
come
or
not.
?I
worry
about
whether
I
hurt
her
feeling.
注意whether和if的使用区别
a.当whether后紧跟or
not时，不用if.
b.介词后面的宾语从句不能用if.
?He
asked
me
whether
I
wanted
to
go
there
by
train
or
by
bus.他问我是想乘火车还是坐公共汽车去那里。
whether...or还有“不管”之意，引导让步状语从句。
?Whether
he
drives
or
takes
the
train,
he
will
be
here
on
time.
不管开车来还是乘火车来，他都会准时到。
c.在强调任意选择时，用whether…or，此时不用
if
替换whether。
?He
asked
me
whether
I’d
move
to
New
York
if
I
got
the
job.
d.
虽引导宾语从句，但为了强调宾语部分，也可把从句放在句首，此时只用whether不用if。
?Whether
he
will
come
I
am
not
sure.
e.句子中有if
引导的条件句，如再有表示“是否”的宾语从句，用whether不用if。
?Please
let
me
know
if
you
need
help.
如果你需要帮助请告诉我。
或：请告诉我你是否需要帮助。对比：
?Please
let
me
know
whether
you
need
help.
请告诉我你是否需要帮助。
f.
容易产生歧义时用whether不用if来表示“是否”。
?I
don’t
know
if
it
won't
rain
tomorrow.
我不知道明天是不是会下雨。
g.
如果宾语从句为否定句时，则只用if不用
whether。
3.由连接代词
who,
whom,
whose,
which,
what
和连接副词
where,
how,
why,
when引导的宾语从句
?Do
you
know
whose
book
it
is
?
?Please
tell
me
when
we’ll
have
a
meeting
.
?
Could
you
tell
me
why
the
train
is
late?
?He
asked
who
could
answer
the
question.
if或whether引导宾语从句时，作“是否”讲，一般情况下，两者常可换用。
在动词不定式之前只能用whether
I
can’t
decide
whether
to
stay.
在
whether
…
or
not
的固定搭配中
I
want
to
know
whether
it’s
good
news
or
not
.
在介词后，只能用whether。
I
worry
about
whether
I
hurt
her
feelings.
宾语从句放在句首表示强调时
Whether
it
is
true
or
not,
I
can’t
tell.
只
用
whether

1.陈述句
2.一般疑问句
