请大家分析两个英语句子
1 kids need a range of authentic role models—as opposed to members of their clique ,pop stars and vaunted athletes.2 They
have to be careful not to come across as disappointed in their child.
(这两句话里面AS各是啥意思,又各引导什么成分)
第一句话里的opposed是过去分词吗,

两句中 " as" 的意思和成分是一样的:做代词,可以理解为 which is.
那么opposed 就能理解了,是which is opposed to...
第一句中的 as 指代的是 " a range of authentic role models"
第二句中指的是一件事," their come cross".
