含蓄条件句

英语中的含蓄条件句是什么意思？！~

解题思路： 英语中某些假设的条件句不是通过if从句表达出来，而是包含在某些短语、上下文或其他方式中，其谓语也常用虚拟语气，我们称此种结构为含蓄条件句。
解题过程：
“含蓄条件句”是指用词组的形式，如介词短语，动词过去分词或现在分词等方式来表达，起到代替条件句的作用。主句中的谓语动词仍可象虚拟条件句那样采用各种虚拟式。含蓄条件句常见的句式有以下几种：
　　
　　一、用介词短语表示
　　
　　1. Without electricity human life would be quite different now.（= If there were no electricity…）
　　
　　如果没有电，今天人类的生活会完全不一样。
　　
　　2. But for the storm, we should have arrived earlier.（= if it had not been for the storm…）
　　
　　要不是由于这场暴风雨，我们一定到得更早。
　　
　　二、用动词过去分词或现在分词表示
　　
　　1. Given more time and money, we could do the work better.（= If we were given more time and money…）
　　
　　假如多给一些时间和钱，我们会把工作干得更出色。
　　
　　2. Not having finished her homework, she could not have been back home.（= If she had not finished her homework…）
　　
　　如果完不成作业，她是不会回家的。
　　
　　三、用转折语气的连词（but, otherwise）表示
　　
　　1. Jack can’t have arrived yet; otherwise he would have telephoned me. （otherwise = if he had arrived）
　　
　　杰克不可能已经到了，要不，他早就给我打电话了。
　　
　　2. Li Ming would have fallen into the well but his uncle caught him. （but his uncle caught him = if his uncle had not caught him）
　　
　　要不是李明的叔叔把他拉住，他就掉到井里了。
　　
　　四、用独立主格结构表示
　　
　　1. Weather permitting, we would go out to have a picnic.（I weather permitted…）
　　
　　天气好的话，我们会出去野餐。
　　
　　2. The heavy rain being over, we would continue marching.（If the heavy rain were over…）
　　
　　大雨过后，我们会继续前进。
　　
　　五、根据上、下文表示
　　
　　该句式可以完全省略条件句，但可根据上下文线索来判断其省略的条件部分。
　　
　　1. Einstein received several baskets of cards, letters and telegrams of congratulation. The gifts to him would have filled a railroad freight car.（省略了If his gifts had been put together.）
　　
　　爱因斯坦收到了满满的几篮子表示祝贺的卡片、贺信和贺电。送给他的礼物之多简直要把一节货车都快装满了。
　　
　　2. Anyone in his position would have done the same.（省略了If anyone had been in the position.）
　　
　　任何人处在他的位置上，都会这么做的。
　　
　　3. We would have succeeded.（省略了If we had kept trying.）
　　
　　我们本来是会成功的。
　　
　　4. I would appreciate a little of your time.（省略了If you were so kind as to give me a little of your time.）
　　
　　给我一点时间，我将不胜感激。
