More examples of type 2 conditional sentences

最近我都在反複講述如何正確地運用 type 2 conditional sentences(有些課本稱它為 pattern 2;名字不重要),因為我發現很多學生都把它用錯。由於上課時間上的限制,我沒有辦法慢慢地去跟你們解釋。希望你們能從這些例子中充份地了解它的用法。


If he had a choice to worry about food or not to worry about food, he would choose not to have to worry about food. 

在上面的 if-clause 中,我們有 "he had a choice to worry about food or not to worry about food"。在 main clause 裡,我們有 "he would choose not to have to worry about food"。

我們都知道,「他有選擇為食物擔心與否的餘地」這句話是不真實的 (unreal),所以我們用 type 2 的 structure (past subjunctive + conditional tense) 去表達 if-clause 中提及的事的不真實性 (unreality):if he had a choice....he would choose.... 


如果你是圖中的男人,你會說 "If I have money" 或是 "If I had money" 呢? 你應該說 "If I had money"。

A: Could you please give me some money?
B: If I had money, I would give it to you.


Imagine that we are in a forest.  If I came across a lion, instead of fleeing from it, I would shoot at it. 

因為以上的句子是虛構性的 (imaginary),我們會說 "If I came across a lion" 而不是說 "If I come across a lion"。之後的 main clause 我們會用 conditional tense: I would shoot at it. (我會向它開槍)
