这道题我在CDE里面实在选不出来, 没办法勉强选A吧! A除了那个grow more than不太好以外,其他都很好

Between 1990 and 2000 the global economy grew more than it did during the 10,000 years from the beginning of agriculture to 1950.

回楼上的:A的后半部分, 你指的it did during the 10,000 years 吗? 过去发生的事情啊, 用过去式啊

这里面是两个过去式的动作在作比较

但是从农业产生的1万年间表达了一段持续的时间，按理应该用完成时啊。during the past 10 years 不是也要用完成时的吗

好象　ＬＥＳ前辈总结过　in/during + the +具体时间　要用完成式的？

晕，　又糊涂了！

不过答案里面没有完成式啊

语法里面，　不是选对的，　而是选最好的！不知道哪位前辈说的

再回头看看这个选项，　如果按照你所说，　那前面部分也应该用完成时啊，Between 1990 and 2000 ，动作也不是持续了一段时间．

我们就把这两段持续的时间都看成两个过去的时间点，　就好理解了

不知道可不可以这样理解呢？

请问grew more than的形式可以存在么，more than不是一定和比较级一起出现么？

小声问一下为什么A中后半部分不用过去完成时？

只是表示过去，并没有过去的过去的意思

grow more than 没问题，A正确，后面during 10000 years那个是个过去的概念，但是没有“发生在过去，影响到现在”的意思，所以可以不用完成式。

Q31:

        

Between 1990 and 2000 the global economy grew more than it did during the 10,000 years from the beginning of agriculture to 1950.

        

                

        

1. Between 1990 and 2000 the global economy grew more than it did during the 10,000 years from the beginning of agriculture
2. Between 1990 and 2000 the growth of the global economy was more than that during 10,000 years, from when agriculture began
3. The
   growth of the global economy between 1990 and 2000 exceeds that which
   had been for 10,000 years from the beginning of agriculture
4. The growth of the global economy between 1990 and 2000 exceeds what it has been for 10,000 years, from when agriculture began
5. The
   growth of the global economy between 1990 and 2000 exceeded what it did
   for the 10,000 years from the beginning of agriculture

        

   Answer: a

        

mine:e

        

why e is not right?

    

~~~~~~~~~~
E中的it 倾向指代growth而不是economy，那么did就指代exceed了，不对。刚做到这题，不知理解的对不？
