Question

you -----have passed the exam if you had worked harder横线中应该填什么？

Answer 1

答案;You【would】have passed the exam if you had worked harder.

翻译：如果你努力学习，你将会通过考试。

解析；这是由if引导的条件状语从句。passed,had worked 等词都用到了

过去时态，所以would也要用过去时态。

Answer 2

you -----have passed the exam if you had worked harder.
解析。这句话是虚拟语气，如果你努力学习，你就可以通过考试。说明他现在没有通过考试，是虚拟语气
拟过去时是表示与过去事实相反的假设，if 从句的谓语形式用过去完成时即had＋过去分词，主句用would / should / could / might + have +过去分词，例如：If it had not rained so hard yesterday we could have played tennis.
所以这里应该填写would
