同意曹老师的说法，存在句哪来什么补语啊！下面是几句有定语和状语的句子：

In the near future there will be a true global village in which telephones, computers and televisions interact. 在不久的将来，会出现一个电话、电脑、电视互动的真正的地球村。（In the near future 是时间状语；in which telephones, computers and televisions interact 为主语的定语）

There was something about herwhich marked her out from the other students. 她有些地方和其它学生不一样。(介词短语 about her 和 which marked her out from the other students 均为主语something的定语)

In those days there were people who lived in the dump and scavenged garbage for a living. 在当时，有人生活在垃圾场，并在垃圾堆里觅食为生。（In those days 是状语，who lived in the dump and scavenged garbage for a living 是定语）
