省略句知识点总结：省略在虚拟条件句型中的应用

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werent, shouldnt, hadnt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.)
