prep2 49 it在比较句中！（非that）

我记得好像只有one和that才是指代前面的中心词。那么it就是指代前面的名词还包括修饰名词的词.

1) 这样这里的it就是指代 more than ten times as much energy。 意思明显不对。

2) prep2-49 A选项里面 it 指代 global economy。 还原后意思没有错误。

Since 1990 the global economy has grown more than “global economy” did during the 10,000 years from the beginning of agriculture to 1950.

3) prep2-49 e 选项里面的it 指代的是 The growth of the global economy since 1990。还原后意思不对

The growth of the global economy since 1990 exceeds what “The growth of the global economy since 1990”  did for the 10,000 years from the beginning of agriculture

不知道49 的e选项如果改成 The growth of the global economy since 1990 exceeds that during the 10,000 years from the beginning of agriculture to 1950 是不是 就对了？

deng同学说的很有道理！~~还有一个问题：96题的case可不可以换成that呢？（case应该也只带中心词吧？。。）
