2 If it rained tomorrow,we would stay at home 这句.
3 If it rains tomorrow,we will cancel the picnic 对未来的推测,用现在.
这2句虚拟语气到底有什么区别
第一句是真实条件句，还是什么的
句子是对的

第一句是虚拟语气.if从句表示与现在的事实相反的假设时,从句的谓语动词用一般过去时,表虚拟.
If it rained tomorrow,we would stay at home.万一明天下雨,我们就呆在家.
If we had enough money,we would buy a computer.如果我们有钱,我们就买台电脑.（事实是我们现在没钱.）
If I were you,I would take her advice.如果我是你,我会接受她的建议.（事实是我不是你）
If places were alike,there would be little need for geographers.
如果各个地方都一样,就不需要地理学家了.（事实是每个地方不都一样）
Our life would be better if there were no examination.没有考试的话,日子就好过多了（现实是不可能没考试）
第二句不是虚拟句,只是一种情况的假设.所以谓语动词不用变为过去时.
If it rains tomorrow,we will cancel the picnic.如果明天下雨,我们就呆在家里.
再问：我知道了，第一句是与现在事实相反，用过去。第二句是，对未来之不确定的假设，用现在。是不是呀
再答：正确！！！
