含蓄条件句

W hat would I have done without you? 1. 条件暗含在短语中。如： W hat would I have done without you? (条件暗含在分词短语without you中) It would be easier to do it this way. (条件暗含在不定式短语to do it this way 中) But for your help we couldn’t have succeeded in the experiment. (暗含条件是but for your help)

2. 条件暗含在上下文中。如： You might stay here forever. (可能暗含if you wanted to) We would have succeeded. (可能暗含if we had kept trying) Your reputation would be ruined. (可能暗含if you should accept it) I would appreciate a little of your time. (可能暗含if you were so kind as to give me a little of your time)
