本题考查if虚拟语气中的用法.此题中有从句我已经通过了考试（would have passed ）,表明从句是过去时,故对过去进行虚拟
全句话的意思就是我要是再努力一点,就通过考试了.由于此题中,主从句的主语都是一样的,故用Had you worked
if虚拟语气和if引导从句的一般将来式的区别如下
if引导条件状语从句的时候,我们分为两种情况,一种是真实的条件,一种是假设,叫作非真实条件状语从句
当IF引导真实条件状语从句,就要遵循我们所说的主将从现的原则,即主句用一般将来时,从句用一般现在时,比如 If all goes according to plan,the first concert will be Tuesday evening.这个就是真实的.
当IF引导非真实条件状语从句时,就要用虚拟语气表达.
1.if + 一般过去时,与现在事实相反,if i were a bird ,i would fly out of the school.
2.if + should/could/would +do,与将来事实相反,if i would finish the job tomorrow,i will call you.
3.if + had done ,与过去事实相反,if i had asked you how to do it ,i would not have made such a fool mistake.
怎么区别,就是看从句的时态,在根据语境判断.

首先主句you would have passed this exam用了将来完成时，则从句要用过去完成时。
Had you worked是倒装句，相当于If you had worked。这种倒装是有规律的，记住它
相信你知道这是
如果你付出了更多的努力，你可以过这个考试的。（考试已经完了，努力的过程也完了）
是过去将来时
条件一般用过去完成时
所以答案选D，
一般类似题目直接找过去完成时
就是那种Had you done something或者是if you had done something
希望采纳~...
