要是我是你、我希望我会飞、他看起来好像认识我、早该睡觉了——当说的不是事实，而是愿望、假设、建议，动词就要「退一格」变成虚拟。这一页带你搞定 if I were / wish / as if / it's time / would rather。

拆成 4 步，一步都别跳：
1记句型（10 分钟） 背 6 个虚拟句型：if I were / wish / as if / it's time / would rather。
2辨时间（10 分钟） wish 后：现在愿望用过去时，过去后悔用 had done。
3做题（15 分钟） 完成 3 道题，检查 were 和过去时表虚拟。
4讲出来（10 分钟） 用费曼三问讲清：为什么 It's time we went 是现在该做。

防坑三则① If I were you 永远用 were，即使主语是 I / he / she——这是虚拟，不是真实条件。 ② wish 后说「现在做不到」用过去时，说「过去后悔」用 had done，别一上来都写过去时。 ③ It's time you went 里用过去式 went 不是过去时间，是虚拟语气，意思却是「现在该走了」。

中国学生高频错误诊断
错误 1：if I was you ✗ If I was you, I would go. → ✓ If I were you… 虚拟条件 be 一律 were。
错误 2：wish 后时态错 ✗ I wish I have more time. → ✓ I wish I had more time. 表现在愿望用过去时。
错误 3：it's time 用现在时 ✗ It's time we go home. → ✓ It's time we went home. It's time sb did 用过去时。

自测三题（点击按钮对答案）
basic填空：If I ___ (be) you, I would apologize.
were。虚拟条件句，所有人称 be 都用 were。
mid填空：I wish I ___ (can) fly.（但愿我会飞，与现在事实相反）
could。wish 表现在愿望，can 倒退为 could。
hard填空：It's time we ___ (start) the meeting.（早该开会了）
started。It's time sb did sth，用过去时表虚拟，意为「现在该……」。
费曼三问：用你自己的话讲清楚
用你自己的话回答这三问① 为什么 If I were you 里是 were 而不是 was？② wish I knew 和 wish I had known，分别对应「现在遗憾」还是「过去后悔」？③ It's time we left 用过去式，为什么说的却是「现在该走了」？
