explain

解释: 绝大多数人读到the elastic characteristics encountered generally change abruptly这一句的时候,第一反应都是把encountered看成了谓语动词,再看到change abruptly的时候又搞不懂怎么会跑出来两个动词,反复看上n遍才看清楚这句话的结构。本句难就难在主语the elastic characteristics 后面的表示被动的过去分词encountered的动作发出者在句子中根本就没有出现过,相当于原文在encountered后面省略了一个by seismic waves ,但是读者却没有心理准备,同时也不熟悉这种分词修饰的方式,因此难以读懂。

另外,这里的which引导的定语从句修饰的是前面整个的句子,即“弹性性质 通常会发生突然的变化 ”的整个事件,使得一部分能量被反射回来。
