新课讲解
虚拟语气在条件句中的应用
条件句可分为两类,
一类为真实条件句,
一类为非真实条件句。非真实条件句表示的是假设的或实际可能性不大的情况,
故采用虚拟语气。
※真实条件句?
真实条件句用于陈述语气,
假设的情况可能发生,
其中if是如果的意思。
※非真实条件句
非真实条件句用语虚拟语气,
假设的情况不可能发生,
或者可能性很小,
其中if
是“要是、如果”的意思。即:“要是……就好了”;
“如果……,
……就会……”

if

和

(supposing),
也可以引导虚拟从句.
If
only
I
had
more
time,
I
could
go
there
to
help
them.
Supposing
it
were
fine
tomorrow,
would
you
go
climbing
the
mountain
with
us?
If
it
were
not
/
had
not
been
for…
也是常见的虚拟句型,意思是“要不是…” 例如:
If
it
had
not
been
for
your
help,
we
would
not
have
achieved
so
much
in
our
work.
If
it
were
not
for
the
wise
decision,
We
could
not
be
living
a
happy
life.
虚拟语气假设条件句型注意点:
1.
假设条件从句谓语动词发生的时间与主句所假设的谓语动词不一致,
叫做错综条件虚拟语气。主句和从句的谓语动词要依照假设的时间而定。
If
the
weather
had
been
finer,
the
crops
would
be
growing
still
better.
If
you
had
followed
the
teacher’s
advice,
you
wouldn’t
be
in
the
hospital.
2.
假设条件虚拟倒装。条件从句中有should,
were,
had三个助动词可以把if省略,
并将这
三个词提至句首。
If
I
were
you,
I
would
give
it
up.
Were
I
you,
I
would
give
it
up.
If
it
were
not
for
your
advice,
we
couldn’t
have
got
over
the
difficulties.
Were
it
not
for
your
advice,
we
couldn’t
have
got
over
the
difficulties.
If
I
had
had
time,
I
would
have
run
round
that
lake
again.
Had
I
had
time,
I
would
have
run
round
that
lake
again.
If
there
should
be
a
flood,
what
should
we
do?
Should
there
be
a
flood,
what
should
we
do?
3.
谓语动词以should
+
have
done的形式出
现的时候,
表示过去应该做而没有做的事
情,
从而表示一种责备的语气。
e.g.
1)
You
should
have
finished
your
homework
yesterday.
2)
You
should
have
come
here
five
minutes
earlier.
3)
He
should
have
told
me
about
it
earlier.
注意:
在虚拟语气的从句中,
动词be的过去时态一律用were,
不用was,
即在从句中be用were代替。
If
I
were
you,
I
would
go
to
look
for
him.如果我是你,
就会去找他。
If
he
were
here,
everything
would
be
all
right.
如果他在这儿,
一切都会好的。

注意:

not
to
do,
而不能说
Weren’t
I
to
do.
