题型：不详难度：来源：
Mike ______have stolen the money from the bank,______he appeared to be rich overnight.| A．can’t; for | B．might; for | C．must; since | D．can’t; since |
|
答案
| B |
解析
试题分析：考查情态动词+have done和连词的用法：句意：迈克可能从银行偷钱了，因为他好像一夜暴富了。For和since都有“因为”的意思，for用于“推测”，since是“既然”，表示说话双方都知道的理由。这句话是推测他偷银行的原因，所以用for，can’t have done不可能做…，must have done过去一定做了，might have done过去可能做了，这里只是有这种可能，选B。 |
