问题
Mary______my letter; otherwise she would have replied before now.
选项
A、has received
B、ought to have received
C、couldn’t have received
D、shouldn’t have received
答案
C
解析
空白处的意思应该是玛丽可能没收到信,所以选[C]couldn’t have received,表示对过去行为的否定推测。在情态动词的推测性用法中must只用于肯定句中.can/could不能用于肯定句中。couldn’t have+过去分词正好与must have+过去分词的意思相反,后者表示对过去行为的肯定推测。
