是对现在的虚拟.found 是过去式
对现在情况的虚拟
条件从句中谓语动词用一般过去式,主句用“would/should/might/could+动词原形”形式,表示对现在不可能实现情况的假想.
If I were you,I would choose to work in a small town.
如果我是你,我会选择在小城镇工作.（事实上我不是你）
If I had a map now,we could easily get out of the forest.
如果现在有地图,我们能很容易地走出森林.（事实上是现在没有地图）这里的ever怎么理解ever这里用作语气词，有强调的意思ever的这个用法能给我举点例子吗Did you ever discoverwhosentyoutheflowers 你到底搞清了是谁给你送来的花了没有？In your country, do people (ever)give flowers as a gift?在你们国家人们到底会不送花当做礼物？
