they get more black eyes than goals.

问题描述:

they get more black eyes than goals.
听"LISTEN TO THIS"中一篇关于阐述足球的段子.
They get more black eyes than goals.这话是指"射空比射中多"吗?
还有一句On dry,hard pitches they break their bones.On muddy ones,they sprain their muscles.其中"on dry"和"on muddy ones"是指干燥的情况下,和泥泞的情况下 为什么要用介词ON.能否举些例子.

关于第二个问题,On dry,hard pitches 意思是“在干燥坚硬的沥青上时”,所以on后的主语实际上是pitches(沥青),而不是dry & hard
同样后面的on的主语是ones,当然啦,同样指代沥青
