  • 解析:(Family environment) (is (widely) believed) (to be) (the most important inflence on children's development).(Family environment) 是主语(is (widely) believed) 是谓语,believe的被动式,中间又夹个了adv(to be) 前面已经有了个谓语,所以这个他用了动词不定式 (to do, to be 形式(属于非谓语动词的一种))(the most important inflence on children's development) 是宾语目测结果:这是一个是主谓宾结构的,用了被动语态以及动词不定式的说.
