and accelerated a phenomenon a phenomenon that accelerated accelerating a phenomenon which, the acceleration of which phenomenon 有以前解释如下: toefl_2003MM的解答: 4. (perhaps )(the most significant postwar )trend was the decentralization (of cities throughout the united states,) a phenomenon( that accelerated) (when massive highway-building programs permitted greater suburban growth.)这样句子成分清晰了吧!
我搞不清that accelerated 如何修饰a phenomenon。 个人认为如that accelerated 是同位语从句,觉得缺少主语。如是定语从句觉得缺少系动词。, 恳请指点。 |
