1、A 考查虚拟语气：“might have done”可以用来表示“本来有可能做某事,事实上却没做”,表达一种婉转的批评或责备.本题是说“他即使很忙也可能帮助你的（但实际上却并没有）”.因为是谈论过去的事情,情态动词应与不定式的完成式连用,排除B和D.C是对过去事实的推测,与后文不符.选A.
考点：考查虚拟语气
点评：在even if,even though 所引导的让步状语从句中,可用虚拟语气,主句、从句的结构与if所引导的条件从句的各种时态、结构相同.如：Even if he were here himself,he should not know what to do.即是他亲自来也不知该怎么办
2、A can表示可能性的推测,常用于疑问句或否定句中；may表“可能性”常用于肯定句或否定句中；must常用于肯定句中表推测,“一定……”的意思．
1.A根据题意 过去完成时 所以选A
2.正确答案是 A. can
How can it be = 怎么能够， 为什么， 何故？
Mr bush is on time for everything. How can it be that he was late for the meeting?
布什先生惯常是准时的。这一次的会议他怎么迟到了？
A
might have done 本可能给你更多帮助
实际上没有，虚拟
A
can,表示否定的猜测 一般用can't的
how can it be怎么可能，意思就是不可能
也就是can't的意思
其他几个都是肯定的猜测
