如何区别,虚拟语气和条件状语从句.
有两个句子：
1 虚拟语气, if i had had enough money, i would have bought a car
2 条件状语从句,if i had eaten breakfast several hour ago, i would notbe hungry now
怎么区分这两种句子啊?
答
真实条件句:表示句子所描述的事件是事实或在说话人看来可能实现的事情.
非真实条件句:表示的条件与事实相反或不大可能实现的事情.
1.If I had had enough money,i would have bought a car.
全句译：如果我当时有钱,我会买辆车.
此句是虚拟语气.因为当时"没钱"是事实,这里只是对当时有钱的一种假设.
2.If I had eaten breakfast several hour ago,i would not be hungry now
全句译：如果几个小时前我吃过早餐,现在我不会感到饿.
此句同样是虚拟语气,而不是真实条件句.
因为几个小时前"没吃早餐"那是事实,这里只是对当时吃过早餐的一种假设.
提问者可能有疑惑,即然是虚拟语气,那为什么主句没用would have been 形式
构成与从句相对应的形式.这里涉及到混合时间虚拟语气（主要是抓住时间状语).主句中有明显的时间状语"now"表现在时间,所以要对现在对行虚拟.
即从句对过去虚拟,主句对现在虚拟.
