one that’s ...从语法角度是定语从句,one代替前面的一句话,也做先行词吗 Family bonding is a massively important element of a child’s development,one that’s constantly undermined in modern society.
我来个简单化. Mary is a good girl ,one that every boy would like to make friends with. 1 one是girl的同位语,也是that的先行词,that是定语从句的连接词,也是定语从句的宾语,make friends with-- - - 是从句部分的谓语. 现在,你明白了吗?
