一题语法题,怎么去做If __________ a man on the moon,why can't they sort out paper-jams?

If __________ a man on the moon,why can't they sort out paper-jams?

选B.
be able to do= can do= manage to do 成功做成了某事.
翻译:
如果他们能把一个人送上月球,为什么竟然不能解决卡纸问题?
再问: CD分别错在哪?
再答: C错在we',后面是they,前面应该也用they才合适。 D的话,说明是if they had landed,这是虚拟语气,表示与真实情况相反,不符合题意。
再问: 这个句子都要前后主语一致吗?不是只有在不是并列句的句子里才要这样吗?
再答: 是的,只有并列句一致是必须的,但是不要忽视虚拟语气哦。 如果说: If we could land a man on the moon,.....这样是没问题的。 if we had landed a man....虚拟语气与现实相反。似乎不太合适。你觉得呢?
