T-4-Q39
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.(逻辑意思不对creatures that appeared表示发生在过去，即过去出现在地球上，现在没有了)

C.Vanished are nearly 99percent 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.（完成时表示发生在过去并一直持续到现在对现在有影响）
选E 括号里是我的理解不知道对不对欢迎拍砖~~

I'd go with E. Besides being generally awkward, B has a verb tense issue. It says "species that appeared" on earth. Appeared is simple past but, in this case, we want present perfect. We use past tense to discuss something that is completely over; we use present perfect to discuss something that started in the past but is either still true or still going on in the present. It is still true that the species appeared, so we want to say "have appeared" - which answer E does use and answer B does not.

B中使用过去式，而过去式用于彻底灭亡消失的物种。
完成时态用于从过去开始，但是可能还是生存或者是现在正在进行灭亡的物种。
现在完成时态更加准确。

如果选择E不是主次颠倒了么
