   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 1 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.)

n.拖拉机,牵引车
  • You must oil the tractor every day.你必须每天给拖拉机加油。
  • He has a tractor.他有一台拖拉机。
