25. If he had taken my advice, he _____ the mistake. Now he regretted not listening to me.
(A) might make
(B) might had made
(C) might not made
(D) might not have made

完整句子：

If he had taken my advice, he might not have made the mistake. Now he regretted not listening to me.

（如果他當時接受了我的建議，他可能就不會犯那個錯誤了。現在他後悔沒有聽我的話。）

文法解析

這是 第三類條件句（與過去事實相反）：

If + 主詞 + had + p.p., 主詞 + might/could/would have + p.p.

例如：

If I had studied harder, I might have passed the exam.
If she had left earlier, she would not have missed the train.

所以：

If he had taken my advice（過去未發生的假設）
→ he might not have made the mistake（過去可能不會犯錯）
其他選項
A. might make ❌（現在或未來語氣，不符合過去假設）
B. might had made ❌（文法錯誤，應為 might have made）
