poorly on being good role models when it comes to dealing with lifes difficulties

不应该是seem to be done
答
这个句子挺容易混淆的,考察的是语态,及主动还是被动语态的问题.seem to be doing 这句的parents只给建议这个动作的主使者,肯定是要用主动语态.如果是advice做主语,它与give的关系是被动,而且选项A也不对,应该为to be...那如果是 seem to give对么。。。也可以，seem to be doing这种用法很少，除非强调动作与seem是一起进行的才用，一般seem to do就可以了。
