这里是填cross 还是crossing啊?为什么呢?我觉得是crossing.可是答案是cross啊!

You should look both ways before you ___the road.这里是填cross 还是crossing啊?为什么呢?我觉得是crossing.可是答案是cross啊!
cross
这里beforeyou ___the road整个在句子中是以从句的形式充当状语,需要填一个谓语动词,如果填ing形式,则应该是把you省略前提下.

cross,这里就应该用动词原形,因为before后面是个完整的句子

第二个单词是must吧 Looking both sides before crossing the road 穿过马路前你最好两边都看一下

cross
因为you后面接的是原形,所以是cross
