TTGWD15-31.39来看看模糊的两道题,谢谢拉

Q31:

As sources of electrical power, windmills now account for only about 2,500 megawatts nationwide, but production is almost expected to double by the end of the year, which would provide enough electricity for 1.3 million households.

1. almost expected to double by the end of the year, which would provide
2. almost expected that it will double by the end of the year, thus providing
3. expected that it will almost double by the end of the year to provide
4. expected almost to double by the end of the year and thus to provide

Eexpected almost to double by the end of the year, which would thus be providing

为什么是E,觉得E肯定错

1. Five hundred million different species of living creatures have appeared on Earth, nearly 99 percent of them vanishing.
2. Nearly 99 percent of five hundred million different species of living creatures that appeared on Earth have vanished.
3. Vanished are nearly 99 percent of the five hundred million different species of living creatures that appeared on Earth.
4. Of five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent of them have vanished.
5. Of the five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent have vanished.

答案上选B,E的都有

,请指教到底是什么??

个人看法，有待商榷：

第二题感觉A不对，因为逗号前后不能在没有连接词的情况下出现两个完整的句子

C不对，因为强调重心改变

B不对，因为appeared 改变了原文的时态，而且只有过去存在现在不存在的才能用一般过去式，原文指有1%还是存在的

D不对，因为这些种族应该加the来表示特指

所以选E

请楼主在标题里面给出题目出处，方便大家回帖，方便后人查询，谢谢啊

另外，多个题目，恳请一题一贴，才能方便讨论！

31题

A which指代不清

B wordy

C 同B

D the best  to double和to provide平行

E 同A

选D

39题B不对,因为

Nearly 99 percent of five hundred million different species of living creatures that appeared on Earth have vanished.

说明这些生物现在已经没有了. 那就是百分之百的消失了

逻辑错误

请问31题B哪里错了

我认为providing修饰整个句子， production provide electricity不合适

请指教

I think one thing is the place of almost. It should mean "almost double". But in B, it is "almost expected".

The other thing is B is wordy by using that clause when "to clause" can be used.
