什么是宾语从句
合作探究一:请观察下列句子宾语的构成:
①
I
have
a
friend.
②
Her
mother
bought
it.
③They
like
reading
the
book.
?Jane
wants
to
have
a
rest.
(名词)
(代词)
(动词不定式)
(动名词)
结论:当宾语可以用一个单词或短语表达时,我们就直接把该单词或短语置于动词后面作宾语,宾语一般由
______________________________来充当。
名词、动名词、代词或动词不定式
合作探究二:
请思考:如何表达“我知道你在看电视”
宾语从句
分析:
宾语是一个完整的句子,无法用一个单词来表达“你在看电视”,只能用句子表达,即:
结论:
这种放在动词后面作宾语的句子,就叫作
__________。
I
know
(that)
you
are
watching
TV.
合作探究三:
宾语从句的种类
1.动宾:
动词后面+句子
I
think
you
are

2.介宾:
介词后面+句子
He
is
sorry
for
what
he
said.
3.be+形容词后面+句子
I
am
not
sure
whether

are
UFOS.
合作探究四:宾语从句三要素是什么?
请观察下列句子:
①I
am
sure
that
he
is
a
bad
boy.
②Do
you
know
whether
Tom
will
come
here?
③He
asked
me
when
I
was
born.
三要素:
引导词,
语序,
时态
合作探究五:引导词
1.由从属连词
______引导的宾语从句
2.由从属连词
__________引导的宾语从句
3.由连接代词
__________________________
连接副词
_________________________
引导的宾语从句,也可理解为由___________引导的宾语从句。
that
whether,
if
who,
whose,
which,what
where,
how,
why,
when
特殊疑问词
(1)由从属连词that引导的宾语从句
that
在句中没有词汇意义,在从句中不能充当成分,只
是使读者清楚后面的句子是前面动词的宾语,在口语当中
往往省略。
一般情况下,当______做宾语时用______引导。
eg.
1.
I
hear.(一小时后他会回来)
-→
陈述句
that
I
hear
(that)
he
will
be
back
in
an
hour.
He
will
be
back
in
an
hour.
2.
He
said.(他非常想念我们)
-→
3.
I
hope.(他们将会玩得开心)
-→
He
missed
us
very
much.
He
said
(that)
he
missed
us
very
much.
They
will
have
a
good
time.
I
hope
(that)
they
will
have
a
good
time.
(2)由从属连词whether,
if
引导的宾语从句
whether
/if
本身作“是否”讲,如果我们要表达一个不确定的概念,就要用whether/if来引导一个从句。一般情况下,如果宾语是__________,就要换成由从属连词____或________引导的宾语从句。
whether和if常常可以互换,但是,当从句后面有
or
not的话,就只能使用whether构成“whether…or
not”的结构。
注:whether/if
后面的句子要用________,即主语在前,谓语在后。
一般疑问句
if
whether
陈述语序
例句分析:
eg.
1.
他问我们周日是否去钓鱼。
在这句话中,“周日我们去钓鱼吗”是一个一般疑问句的含义,所以转换成宾语从句时用whether/if引导。
?
?
-→
He
asks.(主句)
Will
we
go
fishing
on
Sunday?
(从句:一般疑问句)
He
asks
whether/if
we
will
go
fishing
on
Sunday.
2.
我不知道李明明天会不会来。
在这句话中,“李明明天来吗”是一般疑问句的含义,所以转换成宾语从句时用whether/if引导。
?
?
-→
I
don't
know.(主句)
Will
Li
Ming
come
tomorrow?
(从句:一般疑问句)
I
don't
know
whether/if
Li
Ming
will
come
tomorrow.
练习:pair
work
1.
Did
Peter
come
here
yesterday?
Li
Lei
wants
to
know.
(改为含宾语从句的复合句)
Li
Lei
wants
to
know
________
Peter
______
here
yesterday.
2.
Is
Lingling
a
student?
I
don’t
know.
I
don’t
know
_____________________________.
whether/if
came
whether/if
Lingling
is
a
student
3.
我不知道明天是否会下雨。
I
don’t
know__________________________.
4.
李明问我周日是否去北京。
Li
Ming
asks__________________________
___________
5.
老师问我们是否写完了作业。
Teacher
asks
__________________________________.
whether/if
I
will
go
to
Beijing
on
Sunday
.
whether/if
it
will
rain
tomorrow
whether/if
we
have
finished
our
homework
只用whether,
不用if
的情况
1、在带to的不定式前
eg:
2、在介词的后面
eg:
We
decided
whether
to
walk
there.
I’m
thinking
of
whether
we
should
go
to
see
the
film.
3、直接与or
not连用时
eg:
?.我不知道他是否会来。
?.
玛丽问我是否在做作业。
I
don’t
know
whether
he
will
come
or
not.
Mary
asked
whether
I
was
doing
my
homework
or
not.
(3)由特殊疑问词引导的宾语从句。
如果遇到什么时间、什么地点、什么方式、什么原因之类的问句时,我们就要使用相应的疑问词来连接从句。也就是说,当宾语是特殊疑问句时,就要用相应的______来引导。在疑问词引导的从句中,一定要用______语序。
eg.
I
didn’t
hear.(主句)
What
did
he
want
me
to
do?
(疑问语序)
(从句:特殊疑问句)
-→
疑问词
陈述
I
didn’t
hear
what
he
wanted
me
to
do.
(陈述语序)
把一个特殊疑问句放在宾语从句中,我们要做好两步:
1.
移。就是把特殊疑问句中的特殊疑问词移到句子中来;
2.
变。就是把特殊疑问词后面的一般疑问句变为陈述句语序。
e.g.
How
can
I
get
to
the
station?
I
don’t
know.
首先,我们把主句找出来,即:I
don’t
know.
那么接下来是我不知道什么呢?后面就需要一个宾语从句,而后面的句子是以特殊疑问词How来引导,所以,
第一步疑问词移下来变为:
第二步看剩下的部分:
是一个一般疑问句,要改成陈述句,即把主语放到前面:
然后加到前面的句子上。
那么这句话就变成了:
I
don’t
know
how…
I
can
get
to
the
station.
can
I
get
to
the
station?
I
don’t
know
how
I
can
get
to
the
station.

探究练习:合成宾语从句

the
question.
Can
you
tell
me
where
he
is?
Could
you
tell
me
how
I

the
station?
注意这些例句中的陈述语序。
