he acted as if he everything in the world .

问题描述:

he acted as if he everything in the world .
A)knew B )knows C )has known D )won't know 这句话不是虚拟语气吗?为什么不应该用had known

A吧?
他表现的好像他啥都知道.
别想太多啦 这种题就是看你钻不钻牛角尖的
你就把as if 后面当成一个陈述句来看
比如 你表现得好像你是老板一样 就是 you act as if you are the boss 不是you have been the boss
