難點釋疑：
so作“也”講時，引導的句子用倒裝語序。
例如：He went to the film last night.So did I. 他昨天晚上去看電影了，我也去了。
如不作“也”講而只起連詞作用，表示一種結果的意思，句子就要用正常語序。
例如：His mother told him to go to the film.So he did. 他母親叫他去看電影，他就去了。
“He is a tall thin man.” “So he is.” “他又高又瘦?！薄按_實如此?！?BR> Young as he is，he knows a lot. 雖然他年輕，卻知道很多東西。
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。
