翻了一下以前的讨论，貌似支持E的NN稍微多一些~~

我刚看觉得是B，因为简洁，但现在觉得是E了。B的可能的错误应该是appeared和have vanished的关系，看一个NN说“过去出现”会让人觉得现在全都消失了，觉得有点道理~ 还有说B头重脚轻的。。。 但我觉得E的两个完成时也不太合逻辑~~

暂且信E吧。

还有B的five hundred million different species of living creatures 之前少the

肯定E..........這題沒疑問

楼上的给点B的疑问

B用the 解太過牽強...B最不好的地方是appeared跟have vanished時態問題造成句意有出入..(原題是have appeared..這題對外國人來說一樣是很TRICKY的....

看看他們怎麼說...不過我覺得如同老師所說B頭重腳輕違反美國人說話用字的原則...B. '99 percent of five hundred million different species of living creatures' is not idiomatic  這句應該是B不行最主要的原因..而E是合乎說話習慣的講法

Support For B:
—————-
1) B correctly uses past tense to place species on the planet and then present perfect to indicate that the species gradually vanished after appearing.
E is incorrect . Since the species had to appear before vanishing, the use of present perfect in both phrases is incorrect.
2) B is also the shortest one GMAT rewards briefness
3) In E, the clause “99 percent have vanished” doesn’t seem to be proper. is it not preferable to have 99 percent of something in one clause?

Support For E:
—————–
1) Even though E may not be concise, it correctly uses the idiom “Of the…”
2) The 500M species have appeared over time.* Shouldn’t we use “have” (present perfect) to indicate that it was a continuous process. * if they have just appeared at once or in a specific period then that spec. time/period should have been mentioned.
3) B leaves open the possibility that more than 500 million diff species may have appeared on earth. E make is specific - only 500 mill diff species have appeared and 99% of these have vanished.
4) E is correct because it states something (appearing of species) that is continuing even today. B talks about something in past that is not happening now.
6) B is equivalent to:
Nearly 99 percent of [five hundred million different species of] living creatures that appeared on Earth have vanished.
That’s because B does not have “the” before “of five..”
Now, “that appeared” should refer to a past period. Only then it can be correct.
So, B should have been like:
Nearly 99 percent of five hundred million different species of living creatures that appeared on Earth in the so-and-so era have vanished.

恩。。。。3Q~

中场核心

支持语感王道

B读起来就不爽

E的敘述方式是美國人真正會用的~因為文意重點是nearly 99 percent have vanished 真正要告訴對方的重點通常會放句尾 加上OF THE XXXX.....是美國人常用句型

不过,从逻辑上看,B好象有点道理啊!

既然说已经在消失,那这些东西的存在肯定是过去了的.人的死亡是个时刻点,前后分明.

不过确实太不好界限了.

用现在完成时表示消失,而且是一直在消失.

心理感觉是B.如果能正式E的那种分离太远的表达有错就好了。
