You should know better than（ ）into the road.

A.rush
B.to rush
C.rushing
D.rushed
答案选B，但我选A，因为我想这是前后一致原则，前面是”know“，所以后面也要用原型，但为什么不选A呢？最好帮我逐项分析一下，谢谢大家了！

know better than+不定式。这种结构意为“不至于”：
She knows better than to go alone on such a night.
在这样的夜晚，她不至于连不宜单独外出也不知道。
know better than to do sth.的含义是be wiser,better informed,or more
sensible than to do or believe sth.

better by far you should forget and smile than that you should remember and be sad.

笑一笑而忘掉，比愁眉苦脸地记住要好得多。
