SAT OG 里语法题求助
the tribal council`s program familiarized young people with cherokee history,(taught them)B tribal traditions,and (they had)C the (opportunity to)D learn skills used by ancient artists.E
这题我选的是B,因为我觉得这里主语是program而不是人,没办法taught them traditions.可是为什么答案是C啊,

答案是C因为是满足平行结构,即:familiarized young people,taught them tribal traditions,and gave them theopportunity to.三个动词平行.
主语是program没错,但是program是可以taught them 的.意思是这样一个项目.
