很多的喔。。。。
我把我记得的告诉你好了。
if条件句
1.
与现在事实相反
if+did/were
,
主句would
do,should
do,could
do,might
do
2,
与过去事实相反
if+had
done
,
主句
would
have
done
,should
have
done,
could/might
have
done
3.
与将来事实相反
if+were
to/did/should
，
主句would/should/could/might

但这个有个特别点
should的时候，主句还可以接陈述句和祈使句。
.......,he
will
come
.......,let
me
know.
