2019年mpa考试英语真题——虚拟语气311

{01}He studied hard and ____ pass the examination . A.could able to B.could C.was able to D.ought 解析：be able to 含有“经过努力而完成某一动作”的意思，相当于 manage to do 或 succeed in doing，而 can 只“单纯地表示能力或可能”。
本题选C。

{02}I _____ you somewhere before , but your name has escaped me _____ moment . A.must see ; for a moment B.must have seen ; for a moment C.must see ; for the moment D.must have seen ; for the moment 解析：must与不定式的完成体连用表示对过去发生的事持肯定态度的推断，在疑问句中用can，在持否定态度的推断时用can not 。例如：He must have rid himself of his preumonia last week , for you see , he doesn"t cough at all now . (他在上星期肯定治愈了他的肺炎，你看，他现在一点都不咳嗽了。) for a moment表示一个动作延续了一会儿，而for the moment 则表示"目前；暂时"。
本题选D。
