Thank you for all your hard work last week．I don't think we __________ it without you．（ ）

A. can manage

B. could have managed

C. could manage

D. can have managed

题目解答

答案

B. could have managed

解析

本题考查虚拟语气的用法，核心在于判断句子中隐含的假设条件。句中"I don't think..."引导的宾语从句描述的是对过去情况的虚拟（即假设"没有你的帮助"），因此需要用could have done结构表达"本不可能做到"的含义。关键点在于识别时间状语last week和without you所隐含的虚拟情境。

选项分析

  1. A. can manage

    • 错误原因：can manage是现在时态，与句中时间状语last week矛盾。

  2. B. could have managed

    • 正确原因：could have done表示对过去未发生的情况进行虚拟，符合句中"没有你的帮助"这一隐含假设，且与last week的时间一致。

  3. C. could manage

    • 错误原因：could manage是过去时态，但句中需要表达的是对过去情况的虚拟（"本不可能做到"），而非单纯描述过去能力。

  4. D. can have managed

    • 错误原因：can have managed结构不符合英语语法规范（正确虚拟结构应为could have done）。
