Stave said that if he had known how it worked,he would have been told

问题描述:

Stave said that if he had known how it worked,he would have been told

史戴夫(人名随意,有时会依照惯例)说,如果他知道它是怎样运行(工作)的,他早就说出来了

史蒂夫说如果他要是已经知道这是怎么回事,他就应该被别人告知了

这是一个third conditional的句子阿叫做 pass future perfect:过去将来完成时-----------------if he had known how it worked,这后半句用了被动啊 he would have been told-----------------抛开句意原来应该是 if...
