标题: prep2-49, 虽然有看过解释...但是对一个项还是不明白

49. (27096-!-item-!-188;#058&003405)

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

答案是A....

我是在A 和B中想了很久..不是很明白 B那里错了.... 可以帮助解释吗.....

只使用that的话是只指代核心词growth的，所以必须用that of来表示平衡

在GMAT里面from when错误，when要直接接在时间词后面(其他时候from when也有用的)。

谢谢..明白了...对于FROM WHEN这个这么大的错误点居然白痴到没看出来...该打.....

但是对于THAT..因为我知道THAT的指打不是直接的.就是不可以回归原词...(不像IT THEY...)所以是不是可以说这里的THAT就是说THE GROWTH OF ECO... 还是说还是一样用THAT OF ..

那这样的话什么时候用THAT什么时候用THAT OF呀......
