There are hopeful signs that we are shifting away from our heavy reliance on fossil fuels: more than ten times as much energy is generated through wind power now than it was in 1990.
generated through wind power now than it was
generated through wind power now as it was
generated through wind power now as was the case
now generated through wind power as it was
now generated through wind power than was the case
还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
这个句子可以改写成：
more than ten times as much energy is generated through wind power now as in 1990 或 as that in 1990 或 as was the case in 1990
so/such/case可以指代句子/一件事情，如：
No one do so, even though there are more apples in the trees can be picked this year.
The sun ejects red fire, as is the case with any star of similar mass.
Cells secreted hormones, in which case they were endocrine cells.
(1) the second half of the construction 'ten times as much ... ____' is as, not than. therefore, you can eliminate answers (a) and (e), which contain 'than'. (i'm assuming that (e) is supposed to say 'than', not 'then'; i don't think the gmat problems would that blatant an error)
(2) the pronoun 'it' is inappropriate, because 'it' must refer to the ENTIRETY of the noun phrase serving as an antecedent.
for instance, the following is an improper sentence: last year's attendance was ten thousand greater than it was this year
in the above sentence, the pronoun 'it' must necessarily refer to last year's attendance, not just attendance.
the problem in this post has the same issue: the pronoun 'it' must refer to more than ten times as much energy, not just energy - an interpretation that makes no logical sense. therefore, all answer choices containing the pronoun 'it' are wrong.
if you don't like '...than was the case', you should learn to like it; this is one of those phrases that the gmat writers use to refer to concepts that don't fit under the usage constraints of traditional pronouns. (another popular one of these constructions is 'do so'.)
W: the air quality of las vegas was higher in 2007 than that in 1997，前面部分的名词和in 2007之间被谓语动词隔开了，后面that in 1997却没有这样一个动词
R：the air quality of las vegas was higher in 2007 than in 1997，it指代the air quality of las Vegas，两部分时态一致，动词可以省略
R：the air quality of las vegas was higher in 2007 than it was in 1997
扯淡 第一句明显是that of LV in 1997 别复制粘贴就不思考登录 或 注册 后可以参加讨论
2.只能用the case概括，C选项是一个倒装：the case was in 1990
3.as……as结构
做对比局的时候，把as/than前后的成分单独拆开看，C选项是一个倒装：the case was in 1990
只能用the case概括
2. it是关系代词，而每个代词在句子都需要明确的所指代的对象即前置词。从整个句子看，冒号后是个独立完整的句子，句子的主语是more than ten times as much energy，且是该句子唯一的名词，故而it指代的是more than ten times as much energy，注意不是energy。而此处more than ten times as much enery在此处作为it的前置词是无意义的。所以所有使用it的都是错误的选项。

貌似是prep后面的这个事情和主句的事情不需要严格平行。希望毕老师能够回答一下，谢谢！
