语法:
强调句
[品句归纳]
看看以下句子与原句“My
father
did
the
experiment
in
the
lab
yesterday

①It
was
my
father
that
/
who
did
the
experiment
in
the
lab

通过观察以上句子,我们发现:在It
was
和that
/
who之间插入了单词或短语,它们分别是原句的四个成分(主语、宾语、时间状语、地点状语),且这四个句子都是(1)
________
结构,我们把它们叫作it的强调句型。此结构可以强调除
(2)
_________
以外的所有句子成分。强调句中的连接词只用that(指人或物)或who（仅指人），且都不可省略。21教育名师原创作品
[具体用法]
（一）基本用法
1.
强调句的陈述句式
“It
is/was+被强调部分+that/who+剩余部分”
It
was
Lang
Lang
who
held
a
charity
concert
in
Taipei
last
Wednesday.
强调句的一般疑问式
“Is/was
it
+被强调部分+that/who+剩余部分”
Was
it
Li
Ping
who/that
he
met
yesterday
他昨天遇到的是李萍吗？
强调句的特殊疑问式
“被强调的特殊疑问词+is/was
it+that+剩余部分”
How
is
it
that
she
turned
down
our
help
4.
not
…
until的强调句
“It
is/was
not
until
+
被强调部分+that+剩余部分”
It
was
not
until
he
came
back
that
I
knew
the
result.2·1·c·n·j·y
（二）强调句应注意的问题
强调句的判断
如果把强调结构去掉，句子结构完整，那么这个句子就是强调句。如果去掉了强调结构，结构不完整，则句子不是强调句。如：
www-2-1-cnjy-com
①(It
was)
because
he
was
ill
(that)
he
came
here
late.(强调句)
②(It
was)
1998
(that)
she
was
born.（错;1998前加in构成状语作为被强调部分）
易与强调句混淆的几个句式
It
is+时间+when…，when引导的是时间状语从句，主句中的it
指时间，表语由具体的时间充当。
It
was
ten
o’clock
when
we
got
home
last
night.（时间状语从句）
It
was
at
ten
o’clock
that
we
got
home
last
night.
（强调句）
it
was/will
be…before…
过……就……
It
was
not/will
not
be…before…不久……就……
主句中的it指时间，表语多是long,
not
long,
three
days,
two
weeks等表示“一段时间”的词或短语。
It
was
three
days
before
he
went
to
Beijing.
It
was
three
days
ago
that
he
went
to
Beijing.
(强调句型)
[用法检测]
(1)
It
was
_______
back
home
after
the
experiment.

A.
not
until
midnight
did
he
go
B.
until
midnight
that
he
didn’t
go
C.
not
until
midnight
that
he
went
D.

midnight
when
he
didn’t
go
(2)
It

I
that
________
against
you.
A.
am;
is　
B.
is;
is
C.
is;
am
D.
was;

did
