今天研究了很久的一道题 Between 1990 and 2000 the global economy grew more thanit did during the 10,000 years from the beginning of agriculture to 1950. A. Between 1990 and 2000 the global economy grew morethan it did during the 10,000 years from the beginning of agriculture B. Between 1990 and 2000 the growth of the globaleconomy was more than that during 10,000 years, from when agriculture began C. The growth of the global economy between 1990 and2000 exceeds that which had been for 10,000 years from the beginning of agriculture D. The growth of the global economy between 1990 and2000 exceeds what it has been for 10,000 years, from when agriculture began E. The growth of the global economy between 1990 and2000 exceeded what it did for the 10,000 years from thebeginning of agriculture 答案是A。虽然Ron曾经说过研究错误选项怎么改对是没有必要的,但是这个关系到我一直都有点模糊的知识点(时态和比较是软肋啊!),所以一直还是想问一下。 A中的itdid可不可以改成过去完成时(注意不是现在完成时)呢?因为那10000年是在1990-2000这个时间段以前的,而且during也是一个完成时的标志词。我翻遍了CD,很多人问的都是现在完成时,而且这个题好像还有很多变体,有人问了过去完成时,但是解答的我觉得不够有说服力。恳请NN们解答我的疑惑吧!
