我们将学最后一种Conditional——Third Conditional（第三条件的）.
Third Conditional的句子结构：
If＋Past Perfect（过去式分词）＋ .＋would have＋Past Perfect（过去式分词）
1.Third Conditional是用来表达过去式,如果(If)当时那样发生,另外一方面（当时）会如何（通常是指过去的事情,带有一切已经太迟而不能够补救的意思）.
例句(6)：If Ali had studied hard for the subjects,he would have passed the final examination.如果阿里当时勤力地把那些科目读好,他在末考中将会及格.（现在不及格而带有后悔的意思）
2.过去没有发生而感觉到安慰.
例句(7)：If I had not missed my school bus,I would not have been late for school.如果我不错失学校巴士,上学将不会迟到.（现在我来得及而没有迟到）
例句(8)：If I had not taught you,what would you have done?如果我未教你,你将会做了什么?
3.Third Conditional的其它使用方式：
例句(9)：If you had been to the party,you might have met someone special.如果你去过那宴会,你可能已经遇见心目中的人.（当时你没有见到她）
例句(10)：I could have finished the task,if I had had good ideas.我将把那任务做完,如果已经有一些好概念.（但是当时我没有好的概念）
句中的第一个had指的是已经,然而第二个had指的是有.
