当需要表达一个事物附属品的状态，除了用A+ of A和A's A+的结构，还可以借助动词see来表达，A see its A+ do....，将事物当成一个能看见自己所拥有的东西处于的一种状态，当和完成时态结合时，表达一段时期一直所处的状态。经济学人文章经常用到这样的表达。
如经济学人文章最近文章中有这样的句子：
Boeing’s chairman, David Calhoun, has been appointed chief executive and president to “restore confidence” in the company, which has seen its share price tumble since the crashes.
值得注意的是，这样的结构多用于增长或下降的状态中。当然你也可以写成A of B或's的结构表示从属或所属：
Boeing's share price has tumbled sinwww.souquanme.comce the crashes.或
The share price of Boeing has tumbled since the crashes.
但当行文时反复出现这两个表达，会产生枯燥，乏味，单调无聊之感。
