掌握三种经典虚拟倒装，让你告别“If”句式依赖
📘 虚拟语气的倒装形式：你真的掌握了吗？
在英语高级语法中，虚拟语气不仅能表达假设，还能通过倒装结构实现更精炼的表达。这类结构常用于考试作文、演讲或正式语境中，展现语言多样性和表达力。
🧠 举例对比：
- If I had arrived earlier, I could have met her.
- ✅ Had I arrived earlier, I could have met her.
▶️ 定义概括：
将 if 省略，助动词（如 had / were / should）提前构成句首倒装结构，是典型虚拟条件句的升级表达法。
🛠️ 倒装结构分类整理
| 类型 | 例句（常规） | 倒装形式 |
|---|---|---|
| 假设过去 | If he had helped, they would have won. | Had he helped, they would have won. |
| 假设现在 | If I were taller, I’d play basketball. | Were I taller, I’d play basketball. |
| 假设将来 | If she should ask, tell me. | Should she ask, tell me. |
📎 倒装后语义不变，但表达更高级、更地道。
