问题补充:
today, he would get there by Friday.
A. Were he to leave
B. If he had left
C. Did he to leave
D. Had he left
答案:
(答案→)A. Were he to leave
B. If he had left
C. Did he to leave
D. Had he left
解析:句意:要是他明天离开,在星期五之前就会到那里。这里的were he to leave today=If he were to leave today, 为虚拟语气,if条件句谓语中如果有系动词were,助动词should,had可将它提到主语前面,省去if.所以选A。
