考博英语每日一练（8.24）参考答案

1.C

【句意】玛丽不可能收到我的信；否则她之前就会给我回信。

【解析】语法结构——虚拟语气和情态动词的用法。由关键信息“otherwise否则”知“Marry ______ my letter”表示对过去的推测。couldn’t have done表示对过去某事的否定猜测；shouldn’t have done表示“过去本不该做某事却做了”；ought to have done 表示“过去本应该做某事却未做”，故答案选项为C。




2.B

【解析】固定搭配。由句中关键词“challenges encountered in trading贸易中遇到的挑战”的对应知可构成固定搭配“in response to应对”的B项正确。awareness“意识”；contrast“对比”；agreement“协议”。
