Eg.

TV.
如果我做完家庭作业,我就去参加晚会.
If

go/have
gone

如果你昨天晚上不看电视,就不会迟到了.
If
you
hadn’t
gone
to
the
cinema,
you
would
not
have
been
late
for
class.[来源:学科网]
如果你努力地学习的话,你就会考试及格了。
If

you
would
have
passed
the
exam.[来源:学。科。网Z。X。X。K]
The

our
garden__________better
if
it
had
not
rained
so
much
last
year.
A.had
grown
B.would
have
grown
C.were
growing
D.would
grow
Note:
a).条件从句中if
的省略,要倒装
如果条件从句的谓语动词包含有were或助动词、情态动词had,should,could,有时可将连词if省去,而将
条件从句的主语置于were,had,should,could之后。这种用法主要用于书面语,如:
a.与现在相反:If
I
were
you
(=Were
I
you)
,
I
would
go
with
him.
[来源:学#科#网]
???
b.与过去相反:If
I
had
had
time
then
(=Had
I
had
time
then),
I
would
have
gone
with
you.
???
c.与将来相反:If
I
were
to
visit/should
visit/visited
the
Great
Wall
tomorrow,
(=Were
I
to
/Should
I
visit
the
Great
Wall
tomorrow),
I
would
take
my
son
with
me.
???
注意:在否定句中not不可提至主语前,如:
???
(误)Weren’t
I
here
now,
I
would
be
in
the
bus.
???
(正)Were
I
not
here
now,
I
would
be
in
the
bus.
b).without
可以代替条件从句
Eg.没有水和空气,我们就不能生存。[来源:学科网ZXXK]
We
would
not
live
without
water
or
air.
c)
混合虚拟条件句
???
如果条件从句的动作和主句的动作不是同时发生,主句和从句的谓语动词的形式应分别根据各自所表示的
时间加以调整。这种句子叫做混合虚拟条件句。如:
???
If
he
had
followed
my
advice,he
would
be
quite
all
rightnow.(从句述说过去,主句述说现在)
If
China
had
not
been
liberated,the
working
people
wouldstill
be
leading
a
miserable
life.(
从句表示与过去的事实相反,主句说明与现在的事实相反)
d)
省略主句,只保留if(only)的条件句
???
虚拟条件句中的表示结果的主句有时形式上可以省略,但意义仍然存在。这
种句子只保留一个if(only)条
件从句,表达说话人的强烈愿望。如:If(only)she
were
my
sister!她是我的妹妹就好了!
e)
用but或but
for引导含蓄条件句(but后跟从句,but
for后跟短语:
假如没有,
要不是)
???
But
for
your
help,our
experiment
wouldn’t
have
been
sosuccessful.
???
假如没有你们的帮助,我们的实验是不会如此成功的。
???
But
for
the
storm,we
should
have
arrived
earlier.
???
要不是碰到暴雨我们会到得早一些。
???
We
would
have
invited
them
to
the
dance,but
they
were
too
busy.
???
要不是他们太忙,我们会邀请他们来参加舞会的。
???
此句可改写为:If
they
had
not
been
so
busy,we
would
haveinvited
them
to
the
dance.
???
But
that
he
is
in
hospital,He
would
go
abroad
for
hissummer
vacation.
???
要不是生病住院,他就出国度暑假了。
???
该句可改写为:If
he
wereint
in
hospital,he
would
go
abroadfor
his
summer
vacatiom.
f)
"If?only?..."这是一种特殊句式结构
一、"If
only..."用于感叹句中,是一个保留条件句,省略了主句的形式。用来表示某人对某事的一种强烈愿望或未实现的条件,其意为"但愿……;真希望……;要是……就好了"。常用于虚拟语气的谓语动词形式。
If?only?she?were?my?sister!?如果她是我姐姐该多好啊!
(=How?fine?it?would?be?if?she?were?my?sister!)
"If?only..."引导的从句谓语动词形式分以下几种:
1.?If?only后常接一般过去时,表示对现在的一种难以实现的愿望。
如:1)If?only?I?had?that?book!?我要是有那本书就好了。
=How?fine?it?would?be?if?only?I?had?the?book?(but?I?haven't?the?book).
2)If?only?I?were?younger!?要是我年轻点儿就好了!
=How?fine?it?would?be?if?only?I?were?younger!?(but?I?am?not?younger)
3)If?only?my?mother?were?here?now!?要是我母亲现在在这儿就好了。
(but?she?isn't?here?now)
4)How?fine?it?would?be?if?only?they?could?find?a?way?to?get?to?the?room!他们要是能够找到一条通道进入那个房间该多好啊!
2.
If
only后常接过去完成时,表示过去没有实现的愿望。
如:1)?If?only?you?had?worked?with?greater?care!?你当时干活时要是再认真些就好了!
(but?you?didn't?work?with?greater?care)
2)?If?only?we?had?arrived?in?time,?we?would?not?have?missed?the?train!?要是我们及时赶到,就不
会误车了。(but?we?didn't?arrive?in?time)
3.?If?only后常用过去将来时表示将来不大可能实现的愿望。
如:If?only?she?would?win!但愿她能赢!
二、If
only有时也可引导陈述语气的真实条件句,意思为"只要……"。
If?only?it?clears?up,?we'll?go.?只要天一放晴,我们就去。
与此句型容易混淆的还有一种结构"only
if...",only置于if前表示强调if条件,意为"只要……",用于引导陈述语气的真实条件句。
Only?if?you?study?hard,?you?will?pass?the?test.?只要你努力学习,就会通过考试。
