解析
试题分析:考查情态动词表示推测。如果是对过去情况的推测,要使用“情态动词+have done”的形式;如果是对现在的情况进行推测要使用“情态动词+动词原形”;句意:她不可能已经离开了学校,因为她的自行车还在那里。说明是对过去发生的情况的推测。Shouldn’t have done本不应该做某事,实际上却做了;needn’t have done本不需要做某事实际上却做了。故A正确。 点评:情态动词的用法比较复杂。突出的是表示推测:如果是对现在的情况进行推测,使用“情态动词+动词原形”;对过去的情况进行推测,使用“情态动词+have done”;情态动词也经常用于虚拟语气,要分具体情况来分析,在条件句中和宾语从句,表语从句中都有体现。 |
