新概念英语第三册语法总结：虚拟语气
虚拟语气用来表达不可能或难以实现的愿望，与事实相反的假设，通常分为基本的三种形式。
1. 与现在事实相反的虚拟：
If + did / were + …， … would/ should/ could/ might+ do （动词原形）
If I were you， I would go abroad at once.（I am not you.）
If he knew it now， he could help me.（He doesn‘t know it now.）
2. 与过去事实相反的虚拟：
If + had done + …， … would （might） have done …
If I had known your telephone number yesterday， I would have phoned you.（I didn‘t know your telephone number.）
If you had come here a little earlier just now， you might have met her.（You didn‘t come here earlier.）
3. 与将来事实相反的虚拟：
（1） If + should + v.， … would + v.（可能性很小）（译作“万一”）
If it should rain tomorrow， you could stay at home.
If I should fail， what should Ido?
（2） If + did / were to + v …， would + v.（完全不可能）
