has grown since 1990 和 did during the 10000 years 对比

句子结构：… the global economy has grown more than it did… 比较结构。 考点：比较、动词形式 1) 比较，相同比较对象的代词指代，代词that通常不单独使用，后面常跟of…。 2) 动词形式，from…to…连接两个过去的时间范围时，用一般过去时态。 (A) 正确，it指代economy，did指grow的过去时。 (B) 该选项是名词growth之间的对比，表达不准确，more than之间应该有形空词，如fast;from +when引导的从句用法错误，介词from后面应该加名词。 (C) that指代错误，表达罗嗦不清晰;过去完成时态错误，应该用过去时态。 (D) it指代对象不清楚，表达罗嗦不清晰，且exceeds后面应该用过去时态，而不是现在完成时态;from +when引导的从句用法错误。 (E) it指代对象不清楚，表达罗嗦不清晰

Since引导的从句要用完成时，排除CDE

"the global economy" is not followed by any modifiers (as contrasted with "the weather in NY" in your example). so, it has no "character" to transmit to the other part of the sentence; it's just "the global economy (in general)".

这里是抽象的global economy所以it grew 可变成it did has grown 可以和 it did并列使用因为只分be 动和普通动词只不过是过去式和现在完成时所以可行

1 since ...has grown 正确 2. more than it (it 指代 the global economy， 指代清楚） 3 during the period of time (明确时间段用一般过去时）
