4. 在虛擬語氣中，如果非真實條件句省略if，須將主句中的were， had和should等助動詞和主語顛倒形成部分倒裝。例如：
Were he younger （= If he were younger）， he would learn skating. 假如他年輕一些，他就會去學溜冰。
Should they forget （= If they should forget） to bring a map with them， they would get lost in the woods. 如果他們忘記帶一張地圖的話，他們就會在深林里迷路。
Had they realized （= If they had realized） how important the task was， they wouldn‘t have refused to accept it. 假如他們認識到這個任務是多么重要的話，他們就不致于拒絕接受這項任務。
