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。
