Question

一道英语语法题目啊，这题选哪个啊？

Five hundred million different species of living creatures have appeared on Earth, nearly 99 percent of them vanishing.
(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.

Answer 1

选E
B：前面有nearly 99% of，后面的five hundred million different species是特指，需要加定冠词the，所以不能选
C：vanish是不及物动词，不能用被动语态，所以不能选。
D：前面的of结构和后面主句中的of them重复了，造成句子的冗余，所以不能选。

追问

请问B中，能解释详细一点为什么要加the吗？

追答

five hundred million different species of living creatures 后面有用that引导的定语从句 that appeared on Earth来修饰，所以是特指曾经在地球上出现过的5亿生物种族，所以要加定冠词the

Answer 2

A 项不是和题目一样吗？不明白你的意思

追问

A不对。也就是说原文有语法错误，不对。

追答

个人觉得是B
E过去分词短语可表被动或者完成，故have多余
D前已经用了of表所属 与后面的of重复
C Vanished 用错了词性

追问

E中大段的时间概念要用完成时的，我觉得这地方没错啊。而且答案是E。。。
