CPE 考的不是 if I were you 这种初中虚拟，而是倒装虚拟、错综时间、含蓄条件、wish/if only/it's high time 的高级变体。这一课把 C2 条件句家族一次讲透。
⑥ 中国学生高频错误诊断
错误 1：倒装忘了语序❌ Had I have known… ✅ Had I known…（had 后直接过去分词，不要再加 have）。
错误 2：与现在相反 be 动词用 was❌ If I was you… ✅ 正式文体 If I were you（were 用于所有人称）。
错误 3：错综条件时态套错❌ If I had studied, I would be a doctor now 写成 would have been。✅ 主句说现在用 would be。
错误 4：without 后误用动词❌ Without you helped me… ✅ Without your help / Without you helping me，without 是介词，后接名词或动名词。
⑦ CPE 考点与真题风格演练
CPE Use of English Part 4（key word transformations）极爱考倒装虚拟与含蓄条件。
真题风格 1I didn't see you, so I didn't say hello. (HAD)
→ Had I seen you, I would have said hello.
真题风格 2Thanks to your advice, I didn't make a mistake. (FOR)
→ But for your advice, I would have made a mistake.
真题风格 3It's time for us to leave. (HIGH)
→ It's high time we left.

⑨ 口语练习：说出来才算会
跟读 3 遍：Had I known about the meeting, I would have attended.
用自己的话回答：What would you have done yesterday if you had had a free evening?（至少 3 句，用 would have done）
条件反应：听到「要不是…」就用 But for… / Without… 说出英文。
录音回听：用 Were I you, I would… 给朋友一条建议，录音检查 were 的发音。
示范回答If I had had a free evening, I would have gone to the cinema. Had I known the film was on, I would have booked tickets earlier.
