老师晚上好:看到这个句子:Water is necessary for life.学生有了疑问:因为曾看到过这样的论述——主语为具体的物,介词用to。如:The book is important to me.主语为抽象的事,介词用for。如:Studyig English is important for me.望老师点拨。
In my day, if I were to put
on a pair of trousers like they do now, lightning would strike me.这个句子中。前边的 In my day明明是一个过去时间。为什么后边用将来时的虚拟语气呢?是不是应该用与过去事实相反的虚拟语气呢?
原句:The practice provides people with a new interest, animal friendships
and a continuous supply of fresh eggs.老师,这里:a continuous supply of fresh eggs 为什么不是the continuous
supply of fresh eggs,这里用了a是涉及什么语法了吗?
