假设的条件
假设的结果
考点延伸：
1.在if引导的虚拟条件从句中有had,should,were时,可省略if,
把had,should,
were提到句首，
变为部分倒装句式。
If
you
had
come
earlier,
you
would
have
caught
the
bus.
→
Had
you
come
earlier,
you
would
have
caught
the
bus.
如果你来得早些，你就能赶上那辆公共汽车了。
If
I
were
trump,
I
would
be
a
peace
lover.
→Were
I
trump,
I
would
be
a
peace
lover.

If
it
should
rain
next
week,
the
crops
would
be
saved.
→Should
it
rain
next
weeek,
the
crops
would
be
saved.
如果下星期下雨，庄稼就可以保住了。
2.错综时间虚拟句
当条件状语从句表示的动作或行为和主句表示的动作或行为发生的时间不一致时，
动词的形式要根据它所表示的时间做出相应的调整。
If
I
were
you,
I
wouldn't
have
missed
the
film
last
night.
（从句与现在事实相反，主句与过去事实相反）
如果我是你，我就不会错过昨晚那部电影。
If
you
had
taken
the
doctor's
advice,
you
would
be
better
now.
（从句与过去事实相反，主句与现在事实相反）
如果你听从了医生的建议，你现在会好得多。
3.含蓄虚拟条件句
有时假设的情况并不以条件句表示出来，而是通过介词（短语）with,
without,
but
for等来表示。
But
for
(Without)
your
help,
we
couldn't
have
finished
the
work
ahead
of
time.
没有你的帮助，我们就不能提前完成这项工作。
