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.
再问：那这句话是2个主语么？都是you？
再答：后面beforeyou ___the road是一个从句，当主句和从句的主语一致时，一般为了避免重复，常省略后面的you，而以ing形式（主动）出现。
再问：那这里没省略第二个you 那是不是就是二个主语了？
再答：是的，但是后面的主语是从句的。
