Question

置于动词、介词等词性后面起宾语作用的从句叫宾语从句。一般不都是主谓宾吗，为什么介词后还有起宾语作用的从句

Answer 1

宾语分两种 及物动词后面的宾语叫动词的宾语，介词后面的宾语叫介词的宾语。宾语从句也可以充当介词的宾语。有些动介短语 其实相当于一个及物动词 可以把整个动介短语看作谓语 后面的宾语从句 看作这个短语的宾语。如 pay attention to what he is saying.追问

打错了

好吧(∩_∩)你看你看下第三行后面那个句子，people,,,,,,idea已经是个主谓宾句子，但of为什么又链接个宾语从句

第四行，，，╮(>^ω^<)

追答

America is growing older. Fifty years ago, only 4 out of every 100 people in the United States were 65 or older. Today, 10 out of every 100 Americans are over 65. The aging of the population will affect American society in many ways -- education, medicine, and business. Quietly, the graying of America has made us a very different society -- one in which people have a quite different idea of what kind of behavior is suitable at various ages.这里of what。。。。。是介词短语作定语修饰前面的a quite different idea其中what从句相当于一个名词作介词宾语，所以也可以称为宾语从句作介词宾语。介词宾语与主谓宾句型无关
A person's age no longer tells you anything about his/her social position, marriage or health. There's no longer a particular year in which one goes to school or goes to work or gets married or starts a family. The social clock that kept us on time and told us when to go to school, get a job, or stop working isn't as strong as it used to be.

Answer 2

说白了它就是对宾语的补充

Answer 3

介词啊，这东西不影响主谓宾的，就像你平时说话一样，介词就像“的”啊这种的，主要是起连接作用，主谓宾是大结构，后面还有什么定语状语啊之类，都是起修饰或是连接作用的，不影响主谓宾，而且主谓宾并不代表结构一定就是主＋谓＋宾，只是句子中不可缺少的成分罢了（当然有些情况像不及物动词做谓语时宾语也可省略）。

好了就这样，望采纳，谢谢
