省略if的虚拟倒装句

Question

英语省略if的虚拟语气倒装句
有一个例句（省略if 的虚拟语气倒装句）是：
Should you be interested in it ,i can lend it to you.
为什么是Should you 而不是Were you.呢
原句不应该是：If you were interested in it ,i can lend it to you.

Answer 1

省略了if的虚拟条件句中,把were, had或should放在句首时,构成倒装,原句应该是：If you should be intrested in it, I can lend it to you
