有人知道下面这句英文句子用了什么语法
Children need family,but the family seems alo to need children,as the social institution uniquely available,
at least in principle,for security,comfort,assurance,and direction in a changing,often hostile,world

Answer 1

主谓宾+ but + 主谓宾 + as + 主谓宾 （but和as作连词连接三个句子）
但第三个句子里少了be动词谓语,是不是不小心打漏了?
应该是as the social institution is uniquely available,at least in principle
