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

A) Since 1990 the global economy has grown more than it did during the 10,000 years from the beginning of agriculture

B) Since 1990 the growth of the global economy has been more than that during 10,000 years, from when agriculture began

C) The growth of the global economy since 1990 exceeds that which had been for 10,000 years from the beginning of agriculture

D) The growth of the global economy since 1990 exceeds what it has been for 10,000 years, from when agriculture began

E) The growth of the global economy since 1990 exceeds what it did for the 10,000 years from the beginning of agriculture.

Key: A

than后面的it did为什么不是it had？
白勇语法中说道：主语谓语动词短语使用“助动词（如have，has，had，will）或情态动词（can，could，may，should）+verb”形式时，比较从句往往省略verb，保留助动词或情态动词

the 10,000 years from the beginning of agriculture to 1950 是过去的时间段。前后对比的时态不一样

那改成it had?

我认为bej想说的是；
it had意思是it had grown
it did 意思是it grew
这里应该用过去式

那摘录的白勇那句话何解？

那估计要bej回答了，

我的理解是因为这里是过去时，没有助动词也没有情态动词，所以用did 代替verb.
这种省略我认为是比较常见的，我们经常说 ……So do I 。这个do就是代替了前边说话的动词

did就是助动词啦，补充完整就是...more than it grew during the 10,000 years from the beginning of agriculture to 1950.
during the 10,000 years from the beginning of agriculture to 1950是过去的时间段，it had表示过去的过去，语法上来看没有明确的完成时标志，than之前是现在时，之后是过去完成时，之间感觉就会有个时态的gap，既然已经在农业时代开始到1950年的一千年间结束，即不再延续，怎么还可能在1990年之后继续grow并一直到现在呢？这逻辑上也讲不通，你感受下
