Answer 4

选A，这个句子是一个虚拟条件状语从句
if
的条件从句分为真实条件从句和虚拟条件从句。而真实条件从句适用于主将从现，是假设有可能发生的。而虚拟条件从句是假设不太可能发生的。
IF的虚拟语气有三种：
内容
从句
主句
与现在事实相反
动词过去式（be用were）
would/could/should/might+动原
与过去事实相反
had+动词过去分词
would/could/should/might+have+动分
与将来事实相反
should/were
to+动原
would/could/should/might+动原
下面三句依次是上面三种情况的例句：
If
i
were
you
,I
would/could/should/might
do
that.
If
i
had
know
that
yesterday,I
would/could/should/might
have
told
you
.
If
it
should
rain
,the
crops
would/could/might
be
saved.
