问题描述：
If it were not for the fact that you are ill,I would ask you to do this right now.
为什么这里用you are ill,而不是you were ill?不是虚拟语气吗
答
三言两语说不清。
虚拟语气在，if it were not for…已经体现。
答
是虚拟语气 但是不是you are ill这部分 这里虚拟的是这个事实
答
是虚拟语气,但是 YOU ARE ILL 是个事实.
答
句子是虚拟语气，但这个情况比较特殊，虚拟中有真实的成分！the fact that 表明是事实，实际情况就是生病了，这不是虚拟的！
答
前面的it were for the fact that就表明了虚拟语气,
后面的you are ill只不过是充当the fact的内容,the fact现实当然要用一般现在时.
答
这里的 If it were 中的 were 并不是过去式。是假设语气的固定说法。
比这个更特殊的，如果主语是 I 表示假设条件时任然是用If I were。。。
（注意不是was）
