注意4. 含蓄虚拟条件句
有时为了表达的需要，在虚拟语气中并不总是出 现if引导的条件句，而通过其他代替条件句。
I was ill that day. Otherwise, I would have taken part in the sports meet.
He telephoned to inform me of your birthday, or I would have known nothing about it .
问句中用的是虚拟语气，主句用 would have called, 从句 中与过去相反的动词形式为 had done；答句中表示的是 真实的情况，所以该用陈述语气。
注意2.虚拟倒装句
1.Were it (=If it were) not for their help,we couldn’t have got over the difficulties. 2.Had I (=If I had) known about it,I would have told you. 3.Should anyone (=If anyone should )call, please take
2) --- Would you have called her up ___A__ possible? --- Yes, but I _____ busy doing my homework.
