选项:
A、Five hundred million different species of living creatures have appeared on Earth, nearly 99 percent of them vanishing.
B、Nearly 99 percent of five hundred million different species of living creatures that appeared on Earth have vanished.
C、Vanished are nearly 99 percent of the five hundred million different species of living creatures that appeared on Earth.
D、Of five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent of them have vanished.
E、Of the five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent have vanished.
答案:
E
提问：
觉得B好,B直接把主语百分之99的物种来了，而E绕了两下,又有of又有百分之99,雾里不知道主语是谁 时态也认为是B好，B中是appeared，have vanished，感觉两个动作在时间上有区分，语义是：过去存在的，现在灭绝了。但是E中两动作都是现代完成时态，觉得语义和B相比，时态不对。
