⑴、If I were not to make a preparation for my experiment this afternoon, I would have gone to see the film with you last night.
2. 从句表示过去，主句表示将来：
⑴、If they had started the early morning yesterday, they would be here now.
⑵、If we hadn' t made adequate preparations, we shouldn' t dare to do the experiment next week。
3.从句表示将来，主句表示现在：
⑴、If we shouldn't have an exam this afternoon, I would go shopping now.
4.从句表示过去，主句表示现在。
⑴、If they had stared the early morning yesterday, they would be here now.
⑵、If you had followed my advice, you would be able to finish the work now.
