Question

看CNN新闻看到这么一句话

And what better spokeman against distracted driving than someone who wants to race cars for a living...什么意思啊。。。。帮分析一下成分。。。完全搞不懂 what放在这里我连谓语都搞不清了

Answer 1

and what better spokeman(against distracted driving 这是定语 ）than someone（who wants to race cars for a living定语从句）
哪有能比为了生活而赛车的人更适合做一个反对分心的驾驶代言人？

这里有省略的成分： is there

and what better spokeman(against distracted driving 这是定语 ）【is there】 than someone（who wants to race cars for a living定语从句）

反问句，意思是:

there‘s no better spokeman against distracted driving than someone who wants to race cars for a living.
没人能比为了生活而赛车的人更适合做一个反对分心的驾驶代言人？
