题目

\.—When will you come to see me,Dad?—I will go to see you when you _______ the training course.
.—When will you come to see me,Dad?
—I will go to see you when you _______ the training course.
A.will have finishedB.will finish C.are finishingD.finish
假如没有“i will go to see you",后面为什么用finish?

答案

状语从句和主句的动作如果没有发生,则在时态上遵循“主将从现”原则,即主句用一般将来时,而状语从句用一般现在时代替一般将来时.
就算（省略了）没有I will go to see you,由问句中When wll you come to see me也可看出这一点.
再如：I will go fishing if it doesn't rain tomorrow.
如果明天不下雨的话,我会去钓鱼.
