特殊虚拟语气结构
wish从句
现在愿望：过去式（如I wish I knew the answer.）
过去愿望：had + 过去分词（如I wish I had gone there.）
建议/命令类动词（如suggest, demand）
从句用 “(should) + 动词原形”（如He suggested that she leave at once.）
固定句型
It’s time that...：过去式（如It’s time we left.）
as if/though：根据时间选择过去式或had done（如He talks as if he were an expert.）
记忆技巧
时间轴法：
现在相反 → 用过去式；
过去相反 → 用had done；
将来相反 → 用should/were to。
省略if的倒装：
将were/had/should提前（如Were I you → If I were you）。
关键词联想：
wish/suggest等词后必接虚拟形式。
常见错误提醒
避免混淆真实条件句（如If it rains, I will stay.）与虚拟语气。
be动词在虚拟中统一用were（非正式语境可用was）。
