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 milion different species of living creatures that appeared on Earth have vanished.

C)Vanished are nearly 99 percent of the five hundred milion different species of living creatures that appeared on Earth. (強調點不同)

D)Of five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent of them have vanished. (of them 要省)

E)Of the five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent have vanished.

答案給B,

可是,我覺得have vanished怪怪的.

請問這題是不是在考appear及vanish是否能配合完成式?

如果答案是B,表示,appear不能加完成式,vanish 要加完成式.的意思嗎?

不然, 偶覺得E有其可取之處.

此外,B還有一個缺點,即改變了原句的重心,因為感覺上原句的中心思想在說species have appeared,而vanish是副思想.

所以,掙扎在ABE間.

請MM們指點.....

这道题我觉得首先原来句子中nearly 99 percent of them vanishing，them指代不清楚（species或者creatures），至于选项E，appear是瞬间动词，用一般过去式表示曾经出现，用完成时没有道理

謝謝樓上,

但,如果vanish 是瞬间动词，那appear不也該是瞬间动词,因為appear和vanish兩者是相對的,不是嗎?

appear和vanish都是瞬间动词

appearing？什么意思？一直在出现？

同理vanishing？一直处在消失这个过程中？

出现就是出现了

消失就消失了

A.Varnishing不妥，一直出在消失的过程中，【消失了半天^_^】

B。正确，主语清晰，have done意思式已经消失

C。看不出任何需要倒装的理由，且句子显的根本不通顺

D。have appeared ？已经出现，但是后面have vanished？到底是已经出现还是已经消失？另外of显得怪异，意思变成【nearly 99 percent of them】中的five hundred million different species 意思不对了

E。错误同D

这道题我选E,坚信E.虽然答案给出B,我看了很久,仍然不能说服自己选B.所以花了很长时间去搜索以前的讨论稿,更加证实自己的判断.不妨去看看,或许有帮助http://forum.chasedream.com/dispbbs.asp?BoardID=23&ID=83126
