有时条件从句中的动作和结果与主句中的动作，发生的时间不一致，这时动作的形式应根据它所表示的时间加以调整。如：
　　1. 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。

　　2. 从句表示将来，主句表示过去：
　　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.

　　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.

　　6.从句表示现在，主句表示过去
　　⑴、 If I were you, I would have gone to her birthday party.如果我是你，我就去参加她的生日晚会了。 (从句说明现在，主句说明过去。 )

　　7.从句表示过去，主句表示过去和现在
　　⑴、 If you hadn't lent me some money, I couldn't have bought the new house and most likely I would be still living in the dangerous house now.
　　在不少情况下，虚拟式已变成习惯说法，很难找出其暗含的条件。

　　(1)  You wouldn't know. 你不会知道。

　　(2)  I would like to come. 我愿意来。

　　(3)  I wouldn't have dreamed of it. 这是我做梦也不会想到的。

　　(4)  He told the story in such minute detail that he might himself have been an eye-witness. 他将那事讲的非常仔细，简直就象他亲眼看见一样。
