第二部分：用括号内动词的适当形式填空 (Fill in the blanks) - 每题4分，共40分

根据语境，使用情态动词及动词的正确形式（包含对过去情况的推测或遗憾）。

21. I was so lucky. I _______________ (kill) in the car accident. (本可以，但没发生)
22. The ground is wet. It _______________ (rain) last night. (肯定下过了)
23. You _______________ (buy) so much food. We already have plenty in the fridge. (本来不必买，但买了)
24. He _______________ (not see) the boss just now. The boss is currently in London. (不可能看见)
25. I _______________ (finish) the work earlier, but I got distracted by a phone call. (本可以完成)
26. If you wanted to borrow my car, you _______________ (ask) me first. (本应该问)
27. Where is my key? I _______________ (drop) it somewhere on my way home. (可能掉在某处了)
28. She _______________ (be) very happy when she heard the good news. (想必当时很高兴)
29. You _______________ (not tell) him the secret. Now everyone knows! (本不该告诉)
30. — Why is he so late?
    — He _______________ (miss) the bus. (可能错过了)

在整理这30道题时，我观察到情态动词最容易出错的地方在于“时态”与“语气”的结合。例如 must have done 表示对过去的肯定推测，而 should have done 则带有责备或遗憾的色彩。这种细微的差别是机器翻译难以完全捕捉，但人类交流中至关重要的。

我删减了一些过于简单的基础题（比如单纯考察 can 表示能力的题），因为那对提高你的语法水平毫无意义。我更倾向于让你在“推测（Deduction）”和“虚拟/遗憾（Non-fact）”的语境中去思考。
