if条件句可以用过去式吗
这句话没有任何问题。真实条件句可以是对过去作假设。例如，If he missed the first bus, he would be late again. 说话人并不知道主语he是否真的错过了头一班车，只是假设如果这样就会如何，并没有表示与事实相反。

曹老师对四个问题的解答，我在温习是遇到的问题。
我的疑问1：同理He looked at me ，为什么不是终结性持续动词？比如我我看其他地方，现在我看你，导致我看的目标改变。那么状态改变是以什么为参考？ look at sb/sth的动作是可以持续的，你可以连续看几个小时，即这个动作有一个或长或短的持续期，所以它是持续性动词。你look at sb/sth这个动作结束以后，你还是原来...
