英语语法：省略在虚拟条件句中的应用
一、省略连词if
有时可将条件从句的连词if省略，但此时应用倒装句型，即将从句中的were,should,had等提到句首。如：
Were I you,I would stay.倘若我是你,那我就留下。
Should I be free tomorrow,I will come.万一我明天有空，我会来。
Had it not been for the bad weather we would have arrived in time.若不是天气坏，我们就准时到达了。
注：①若条件从句为否定句，否定词not应置于主语之后，而不能与were,should,had等缩略成weren't,shouldn't,hadn't而置于句首。
②有时省略if后提前的had不是助动词。如：
Had I time,I would come.假若我有时间，我会来的。(=If I had time…)
二、省略从主语和动词be
若主从句主语一致，且谓语部分包含有动词be，通常可将主语和动词be省略。如：
If repaired earlier,the tractor would not have broken down.要是早点儿修一下，拖拉机就不会抛锚了。(=If it had been repaired earlier…)
三、省略“it+be”
If necessary,I would send more farm-hands to help you.如果需要的话我会派更多的民工去你。
四、省略整个条件从句
这样的省略通常需要借助一定的上下文，即省略条件从句后，所剩下的主句的意思在一定的上下文中意思是清楚的。如：
I might see her personally.It would be better.我可以亲自去看她，这样好一些。(=…If I saw her personally,it would be better.)
