2019年mpa考试英语真题——虚拟语气373

{01} Since the road is wet this morning, _____ last night. A.it must rain B.it must be raining C.it must have rained D.it must have been rain 解析： must have done用于对过去发生的事情进行推测，且较有把握。
本题选C。

{02}Had it been possible I would have gone to the movies but I _____ busy. A.had been B.am C.was D.would be 解析：but前的句子是一个与过去事实相反的虚拟语气， but后引出了一个过去事实,说明不去看电影的理由。故用一般过去时。
本题选C。

{03}My aunt _____ here by now, for she took the early bus.
A.must arrive B.can arrive C.may arrive D.ought to have arrived 解析：ought to除了可以跟should一样表示“应该”之外，还可以表示推测，“照理应该”，而must表示相当肯定的语气，“一定；必定”，本题还着重考查正确使用时态，表示到目前应该已经发生用ought to +完成时态。
本题选D。
