这个题我是这样看的.大家讨论哈,我发现我的理解和172的解释不一样,大家看看,有错误帮我指出来.

这个句子是个倒装.正常语序应该是energy is generated through wind power now more than ten times as much as (energy) was the case in 1990.这样看来,这个比较关系就清楚了.the case 指的就是generated through wind power这么个事情.

为什么会倒装呢?因为正常语序中的被动语态使得more than ten times 离修饰对象energy太远,不好,所以就倒装了.

解题的时候为什么会看出是倒装呢?因为第二个as后面如果出现句子的话,必然和主句中的S+V比较,可是发现主句(我指的是冒号后的部分)没有主句,所以就猜测出现了倒装.并且,第一个as后面一般是adj/adv/n.这里名词不可能--根据逻辑意思看的.

大家看,是不是这么回事?

那么这道题的it指代不也有问题吗：

27. Since 1990 the global economy has grown more than it did during the 10000 years from the beginning of agriculture to 1950.

A. Since 1990 the global economy has grown more than it did during the 10000 years from the beginning of agriculture
    

B. Since 1990 the growth of global economy has been more than that during 10000 years, from when agriculture began

这题好像至今都没人回答阿?

同问!

可以参见大全393

393.     In one of the bloodiest battles of the Civil War, fought at Sharpsburg, Maryland, on September 17, 1862, four times as

           many Americans were killed as would later be killed on the beaches of Normandy during D-Day.

如果在后边比较的部分改为"they whould later be killed..."，你肯定觉得不对吧．

可以比较一下：

1). wind power generates ten times as much energy as it did in 1990.　主语没有变化，比较的是相同主语在不同时间的行为

2). more than ten times as much energy is generated through wind power now than it was in 1990    主语发生变化，故不能用it向前指代．

比较对象的不同：

27题  同样的经济增长在不同年代时的比较，是可以用it的

29题 1990的产生能量和现在产生的能量是完全不同的，不可以用it代替
