she has a lot of experience dealing with teenager's problems.这里为什么用dealing?
答
现在分词短语作后置定语修饰experience
这句话的简单句是she has experience 她有经验， a lot of ，dealing with teenager's problems都是定语，修饰experience的
类似的结构有
the man smoking isn't my teacher ,抽着烟的那个人不是我的老师
答
dealing with 是现在分词短语作定语的用法，修饰experience。
她在处理少年问题上有很多经验。
答
dealing 做experience的后置定语.当然,不定式也可做后置定语,但表示还没做或将做的事,如I have something to eat .而现在分词做后置定语表示主动.还有,过去分词也可做后置定语,但表示被动.
