Question

详细分析一下语法，谢谢

There are too many complaints about society ———— move too fast to keep up with the machine.
A. that have to B. have to
C. having to D. has to

Answer 1

对啊，选C。
complain about 后面要么是名词/要么是ing结构。你可以把society having to 理解为society's having to

追问

society 与having to 在语法上都做什么成分啊，

Answer 2

选A 定语从句。

追问

答案貌似是C，但是不清楚为什么，如果选A主谓不一致啊

追答

对，选C。后面是动名词的复合结构，说成：society's having to 也可以
