祈使句+and+陈述句（是一种什么关系）

Ask him again, and he will tell you.

If you ask him again, he will tell you.

这个句子答案填and，相当于一个条件句If you ask him again, he will tell you.

and前后两个句子是顺承关系还是条件关系？这个题该怎么解析呢？

解析如下：

祈使句（表条件）+ and +主句（表结果）

(1)祈使句（表条件）+ or else/or/otherwise + 主句（表结果）…… “否则……，要不然……”

=If you don't hurry up, you will be late.

如果你不快点，你会迟到的。

你来之前打个电话，否则，我们也许会出去。

(2)祈使句（表条件）+ and +主句（表结果）

Think it over and you will find the answer.

=If you think it over, you will find the answer.
