强调句的用法
强调句型的构成是:it
is
(was)
+
被强调部分+
that
(who)
+
句子的其他成分。被强调的部分放在
it
is
(was)
之后,其它部分置于that之后。被强调部分可以是主语,宾语,表语或状语。强调的主语如果是人,可以由who代替that。
1.
被强调的成分举例:
原句:tom
found
my
pen
in
the
classroom
yesterday.
强调主语:it
was
tom
who
/
that
found
my
pen
in
the
classroom
yesterday.
强调宾语:it
was
my
pen
that
tom
found
in
the
classroom
yesterday.
强调地点状语:it
was
in
the
classroom
that
tom
found
my
pen
yesterday.
强调时间状语:it
was
yesterday
that
tom
found
my
pen
in
the
classroom.
2.
强调句型的一般疑问式:
直接把is或was提到it之前即可。例如:
was
it
tom
that
found
your
pen
in
the
classroom
yesterday?
3.
强调句型的特殊疑问式:
特殊疑问词+
is
(was)
it
+
that
+句子的其他成分。特殊疑问词即是被强调的成分。例如:
who
was
it
that
found
your
pen
in
the
classroom
yesterday?
4.
that
(who)
有时可以省略:
这种强调句型中的that或who有时可以省略。例如:
it
was
my
brother
(that
/
whom)
you
saw
the
other
day.
5.
强调原因状语从句要注意:
若从句由as或since引导,强调时则改为because,这是因为,because引导的原因从句表示的意义非常强烈,符合强调句的目的。例如:
as
she
got
up
late,
she
missed
the
first
bus.
变为:
it
was
because
she
got
up
late
that
she
missed
the
bus.
6.
强调句的否定转移:
有些否定句在变成强调句时,要把否定转移到被强调的词语之前。尤其是“not...
until...”句式的强调要特别注意。例如:
he
didn't
realize
his
mistake
until
the
teacher
had
told
him.
变为:
it
wasn't
until
the
teacher
had
told
him
that
he
realized
his
mistake.
【注意】
在强调句式中,虽然not被提前,但“not...
until...”句型不要倒装。
高考中强调句型考查热点
考点一:强调句型的基本结构
强调句型“it
is
/
was
+
被强调的成份
+
that
+
其他成份”用来强调主语、宾语和状语等成份。that只起连接作用,不作成份,但不能省略。有时强调的部分比较特殊,如主语从句、状语从句、名词、不定式短语、v-ing的复合结构等。如:
it
was
in
the
library
that
i
saw
her
yesterday.
我昨天正是在图书馆见到她的。
考点二:特殊句式中的强调句型
1.
如果强调的是特殊疑问句中的疑问词,表示“到底”、“究竟”等语气时,就用如下结构:
“特殊疑问词
+
is
/
was
+
it
+
that
+
该句的其余部分”。如:
how
is
it
that
you
usually
go
to
work?
你通常是怎样去上班的?
2.
在强调“not...
until”结构中由until所引导的短语(或从句)作时间状语时,要用固定的强调句型:“it
+
is
/
was
+
not
until...
+
that
+
该句的其余部分”,that所引导的从句中的谓语动词用肯定式。如:
his
father
didn't
come
back
from
work
until
12
o'clock.
=
it
was
not
until
12
o'clock
that
his
father
came
home
form
work.
直到12点他的爸爸才下班回家。
考点三:强调句型与时间状语从句、定语从句的判断
强调句型要注意和it代表时间、距离、温度、自然现象、具体事物或人物等时所构成的各种句型的区别。试比较:
it
was
on
march
1
that
i
had
my
hair
cut.
(强调句)
it
was
march
1
when
i
had
my
hair
cut.
(后面是定语从句)
判断是否是强调句,可采用“还原法”。如果还原为一般句式后,句子各种成份完整,则是强调句。否则不是。如第一句可还原成:i
had
my
hair
cut
on
march
1.
考点四:偶尔考查谓语动词的强调句式
英语中常用助动词do、does或did强调谓语。如:
he
did
go
to
the
airport
yesterday,
but
he
didn't
find
you.
他昨天确实去了机场,但他没有找到你。
助动词表示强调的用法
助动词表示强调,放在动词前面,根据时态、单数、复数的不同,其形式可以是do,did,does。
助动词后面的动词用原形。如:
1. He does like me.
2. Tom did come here yesterday.
3. They do have nothing to say.
do
英 [duː , də , dəʊ] 美 [duː , də , doʊ].
v.(以某种方式)做;办(某事);行动;表现;(问询或谈论时用)进展。
