特例

2.省略If的条件从句
如果条件句中有were/had（助动词）/should时，可使用倒 装句结构——省略If，把were/had（助动词）/should放句 首。如果条件句是否定句时，not应置于主语后，不能与 were/had（助动词）/should等缩略成 weren’t/hadn’t/shouldn’t. 例：Had I seen him then, I would have been very happy. =If I had seen him then, I would have been very happy. Should I have time, I would go with you. =If I should have time, I would go with you. Were I not so busy, I would go to the concert. =If I weren’t so busy, I would go to the concert.
特例

1. 错综时间条件句
定义：主句和从句动作发生的时间不同 例1） If they had studied hard, they could finish the work in a very short time.如果他们当时刻苦学习，现在就能快速 完成这份工作了（从句说明过去，主句说明现在）。
Practice
1. If you had told me in advance, I ____ him at the airport. A. would meet B. would have met C. would had met D. should meet

Practice
1. If you had told me in advance, I ____ him at the airport. A. would meet B. would have met C. would had met D. should meet
与过去相反，以前没有刻苦学习
与现在事实相反，现在没有快速 完成
2）If I were you, I would have gone to her birthday party yesterday.如果我是你，我就去参加她昨天的生日聚会了 （从句说明现在，主句说明过去）。
♦ 要根据动作发生的时间选择恰当的动词形式。
