题目内容
9.Your teacher was really worried about you.You couldn't have left school without telling him.分析 你的老师真的很担心你.你本不应该不告诉他就离开学校.
解答 75.couldn't 改为shouldn't 这里考查情态动词+have done的用法. couldn't have done表示"过去不可能做了某事",不符合本句子的逻辑. shouldn't have done:本不应该做某事却做了,本句意思为"本不应该离校却离校了",故改成shouldn't.
点评 情态动词+have done是高考的高频考点,需要平时多加记忆.
