风唱梵音你好.【表示与现在相反】从句：主语+过去时 　　主句：主语+should/would/could/might+do eg.If I were you,I would take an umbrella.如果我是你,我会带把伞.（事实：我不是你） 2.If I knew his telephone number,I would tell you.如果我知道他的电话号码,我就会告诉你.（事实：不知道）【表示与过去相反】从句：主语+had done 　　主句：主语+should/would/could/might+have done　 eg.If he had taken my advice,he would not have made such a mistake.如果他听我的劝告的话,就不会犯这样的错误了.（事实：没有听我的话）======以下答案可供参考======供参考答案1:你可以参考资料啊供参考答案2:主要是看虚拟证语气的这个句子所写的事情是发生在过去还是现在,如果是在讲述现在的愿望或者是与现在不可能实现的事情,则用与现在事实相反的虚拟句,如If I were a bird , I could fly in the sky. 如果是过去的愿望或者是与过去发生事实相反的事情则用与过去事实相反的情况,如:If I had bought the book yesterday, I would have sent a gift to my brother.

我也是这个答案
