探究一：
宾语从句
在复合句中充当宾语的从句叫宾语从句，就是用一个句子来构成主句的宾语。看上表格：
探究宾语从句的用法，要从概念、引导词、主句从句时态以及宾语从句的语序这几个方面探究。
探究一：宾语从句
1.概念：什么是宾语从句？(略)
第二单元已学，不再重复
2.宾语从句的引导词

Grammar

a.
Could
you
tell
me
who
he
is
waiting
for?
b.
Our
teacher
said
(that)
the
earth
goes
around
the
sun.
c.
I
don’t
know
if
he
will
come
tonight.
d.
I
am
thinking
about
what
he
said.
e.
I
wonder
if\whether
he
will
come.
观察下列句子，请圈出宾语从句的引导词。
回顾：宾语从句有三类引导词。
1.由
that
引导的宾语从句，无意义，可省略。如a.句。
2.
由whether(or
not),
if
引导的宾语从句，翻译为“是否”
，不可省略。if/whether可互换,
但whether…or
not为固定搭配.
如c.
e.句。
2.宾语从句的引导词
3.
引导词除了可以用that,
whether
,
if
,
还可以用where，how，
when，who
等
____________.
特殊疑问词
知识拓展：把下列直接引语变成间接引语
1.
He
says,
“Tom

a
good
student
”.
2.
She
tells
me,
“I
don’t
like
sports
”.
3.
“Can
you
finish
it
by
yourself?”
he
asks.
4.
”Who

Do

know?
5.
“Can

探究一：宾语从句
2.宾语从句的引导词
发现：1.
直接引语是陈述句转换成间接引语时，宾语从句用that引导。
that
无意义，可以省略。如1.
2.句。
2.
直接引语是一般疑问句或反意疑问句变成间接引语时，宾语从句
用if\whether引导。if\whether不能省略。如3.
5.句。
He
says,
“Tom
is
a
good
student
”.
He
says
________________________.
that
Tom
is
a
good
student.
“They

Great
Wall,
won’t
they?”
he
asked.
He
asked
__________________________________________.
if
(whether)
they
would
go
to
visit
the
Great

3.
直接引语是特殊疑问句变成间接引语时，宾语从句用原来的who\what
等特殊疑问词引导。特殊疑问词不能省略。如4.
6.句。
“How
can
we
get

I
wonder.

2.宾语从句的引导词
疑问词引导的宾语从句
疑问词what,
who,
whom,
whose,
which，when,
where,
how,
why可引导宾语从句，它们在从句中可作主语、宾语、表语、定语或状语等。
I
don’t
know
who
will
teach
us
chemistry.
（作主语）
I
wonder
what
I
need
to
prepare
next.
（作宾语）
We
wonder
whose
this
car
is.
（作表语）
Could
you
tell
me
which
bus
I
can
take
to
the
art
museum?
（作定语）
注意：
当疑问代词在宾语从句中作主语时，宾语从句语序不变；另外含有宾语从句的句子的句末标点由主句决定。
Can
you
tell
me
when
she
will
be

观察下列句子，根据句意用所给动词的适当时态填空。

his
father
came
back.
was

will
cook
is
singing
has

was

发现：当主句是一般现在时，宾语从句的时态不作限制，我们可以根据句子的需要使用任何一种时态。
需要性原则
主现从不限
探究一：宾语从句
3.宾语从句的时态
1)
He
will
go
to
Hong
Kong
.
2)
He
is
sick.
3)
He
is
reading
a
book
.
4)
He
has
finished
his
work.
He
said
He
_________

Hong
Kong
.
he
_____

he

book
.
He

work.
将下列句子放在宾语从句的位置，用动词的适当时态填空。
would
go
was
was
reading
had
finished
发现：当主句是一般过去时的时候，宾语从句必须运用相应的过去时态，从而达到主句和从句的相互一致。
呼应性原则
主过从也过
探究一：宾语从句
3.宾语从句的时态
注意:当宾语从句表达的是客观事实(真理、自然现象、名言、警句、谚语等)的时候,其时态不受主句的影响,仍是用一般现在时态。
观察下列句子，根据句意用所给动词的适当时态填空。

did
you
find
out?
探究二：疑问词+不定式
当宾语从句中的主语与主句的主语或宾语一致时，可使用“疑问词+动词不定式(短语)”结构对从句进行改写。如：
I
really
don’t
know
which
book
I
should
buy.
=
I
really
don’t
know
which
book
to
buy.
Can
you
tell
me
where
I
can
get
a
dictionary?
=
Can
you
tell
me
where
to
get
a
dictionary?
含有宾语从句的复合句与简单句的转换
(1)若主句的主语和从句的主语一致，可以将疑问词引导的宾语从句转化为“疑问词＋动词不定式”结构。
I
don’t
know
what
I
should
do
next.
=
what
to
do
(2)若主句的谓语动词是hope,
agree,
wish等，且主句的主语和从句的主语一致时，可以将that引导的宾语从句转化为动词不定式结构。
She
hopes
that
she
can
get
good
grades.
=
to
get
(3)若主句的谓语动词是see,
hear,
watch,
notice等时，其后由that引导的宾语从句可以转化为“宾语+宾语补足语(动词原形/动词-ing形式)”。
I
heard
that
two
girls
were
singing
in
the
next
room.
=

V.阅读理解
When
you
try
to
contact
an
old
friend
you
haven't
seen
for
many
years,
do
you
choose
to
make
a
call
or
send
a
message?
Many
people
may
choose
to
send
messages
so
that
they
won't
feel
embarrassed.
However,
new
research
has
found
that
making
a
phone
call
is
the
best
way
to
get
in
touch.
In
the
study,
researchers
did
all
kinds
of
experiments.
In
one,
they
asked
200
people
to
make
predictions
about
what
it
would
be
like
to
contact
an
old
friend
by
e?mail
or
by
phone.
Then
the
people
did
one
or
the
other.
Although
people
supposed
that
a
phone
call
would
be
more
embarrassing,
hearing
someone's
voice
actually
made
the
experience
better.
In
another
experiment,
the
researchers
had
strangers
connect
by
sending
messages,
talking
over
video
chat,
or
talking
using
only
audio(音频).
They
found
that
both
forms
of
voice
communication—whether
video
or
audio
only—made
the
strangers
feel
more
connected
than
communicating
by
sending
messages.
Many
people
choose
to
send
messages
or
e?mails
instead
of
calling
because
they
think
it's
convenient.
What's
more,
they
think
it's
a
form
that
can
be
controlled.
In
fact,
sending
messages
or
e?mails
can
make
it
hard
to
find
out
the
true
meaning
behind
a
conversation.
A
phone
call
is
actually
more
convenient
than
sending
messages.
When
calling,
both
can
know
about
the
meaning
behind
the
conversation.
There
is
no
need
for
them
to
think
about
the
possible
meanings
behind
words.
So
if
you
want
to
feel
more
connected
to
the
people
you're
talking
to,
you
should
call
them
instead
of
sending
messages.
( )21.Why
do
many
people
choose
to
contact
old
friends
by
sending
messages?
A.
To
avoid
feeling
embarrassed.
B.
To
communicate
better.
C.
To
save
more
time.
D.
To
be
more
convenient.
( )22.What
did
the
200
people
do
in
the
experiment?
A.
They
talked
to
old
friends
face
to
face.
B.
They
chatted
with
old
friends
on
the
Internet.
C.
They
called
or
sent
messages
to
old
friends.
D.
They
talked
with
old
friends
by
only
using
audio.
( )23.What
do
researchers
find
in
the
experiments?
A.
People
prefer
listening
to
someone's
voice.
B.
Sending
messages
may
make
people
embarrassed.
C.
People
feel
more
connected
when
getting
messages.
D.
Sending
messages
is
more
convenient
than
calling.
( )24.What
can
we
know
from
the
fourth
paragraph?
A.
Sending
messages
is
actually
more
convenient
than
making
calls.
B.
It's
hard
to
know
the
true
meaning
behind
the
conversation
by
sending
messages.
C.
Calling
is
a
form
that
can
be
controlled.
D.
There
is
no
need
to
send
messages.

passage?

Reasons
You
Should
Call
Instead

B.
