其它注意事项?/p>
1.
错综复杂的时间条件句?/p>
主句和从句的动作不是发生在同一时间?/p>
其动词形式要根据时间而定?/p>
例如?/p>
If he had taken the medicine, he would be all right now.
If I were you, I would
have gone with him.
2.
If
的省略与倒装?/p>
在正式文体中,有时可省去
IF
。而将从句?/p>
were,had,should
提到主语前。例
如:
1.Were she here(=If she were here),she could give us help.2.Had he not left so
early(=If he had not left so early), he might have missed the bus.3.Should it rain
tomorrow(=If it should rain tomorrow), I would sleep for a day.
3.
含蓄条件有时虚拟条件不用从句
,
而用介词
?/p>
without,bu for
?/p>
例如?/p>
Without(=But
for)air(=If
there
were
no
air),
wre
couldn
?/p>
t
live.
2.I

busy,now.
Otherwise,
I
would help you. 3.It would be wrong not to help him if we were not to help him.
