If she had caught the bus,she wouldn't have been late.If you had paid attention,you wouldn't have made so many mistakes.虚拟已经过去了的事情要用过去完成时（基本原则是看原句用的过去时，变虚拟语气就用过去完成时）My friend Rita called.She said me if I saw her on TV last night.The police officer asked me my name is.(这句可直接说asked me my name)if she catched the bus, she will not be late.if you payed attention, you will not make so many mistakes.
