prep198,196 3个小问题，求解答~~~

198.(GWD-18-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.

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

B.Between 1990 and 2000 the growth of the global economy was more than that during 10,000 years, from when agriculture began

C.The growth of the global economy between 1990 and 2000 exceeds that which had been for 10,000 years from the beginning of agriculture

D.The growth of the global economy between 1990 and 2000 exceeds what it has been for 10,000 years, from when agriculture began(A)

E.The growth of the global economy between 1990 and 2000 exceeded what it did for the 10,000 years from the beginning of agriculture





A. Correct；it完全指代the global economy，并不特指1990到2000年之间的global economy

小菜有个问题，关于it指代问题~
我记得prep上说it是完全指代，也就是说，包括修饰核心词的修饰语~那么对于A的这个时间段，我一直认为这个包含在“修饰核心词的修饰语”中，所以我就把A排除了。。。但是错了。。。这是为什么呢，这个时候为什么时间修饰就不是修饰语了呢？

再来一道~
196.(GWD-1-Q41)Leaching, the recovery of copper from the drainage water of mines, as a method of the extraction of minerals, it was well established as early as the eighteenth century, but until about 25 years ago miners did not realize that bacteria take an active part in the process.

A.as a method of the extraction of minerals, it was well established

B.as a method of the extraction of minerals well established

C.was a well-established method of mineral extraction

D.was a well-established method of extracting mineral that was(C)

E.had been a method of mineral extraction, well established



1，小菜对于C&D没区分开~
虽然prep上的解释说，as early as the eighteenth century是修饰前句的，但是这怎么就不能修饰method呢，而且拿什么说这个时间状语是修饰前句而不是修饰别的名词呢~

2，prep上的解释说well established做非限定性修饰逻辑含义错误，这个怎么理解？

就酱，麻烦nn们帮我看看，能说一点是一点~先谢谢各位啦，抱拳啦

Between 1990 and 2000 与 during the 10,000 years from the beginning of agriculture这两个时间段不是先 ...

同LS 同问.

Between 1990 and 2000 与 during the 10,000 years from the beginning of agriculture这两个时间段不是先后发生的么，到底在GMAT中对于时间先后或者动作先后是怎么界定的呢？请教？

Between 1990 and 2000，状语，修饰grow

另外我有个问题，对于198这道题，为什么A选项的两个一般过去时都是正确的呢，这两个动作不是先后发生，应该用过去完成时的么？

貌似不是我想多了，这点我之前好像特意问过baby姐，有一点印象~~

还有一个问题是小菜突然想到的：
prep中有说：“the growth of sth. was不如sth. grew简洁；from when agriculture began to 1950的不如from the beginning of agriculture to 1950好”

那么我想问，像这样简洁性的问题，是不是最后考虑？
也就是说，如果正确答案里面有类似“the growth of sth. was或者from when agriculture began to 1950”的结构，那么可以忽略不计吧，因为这只是简洁与否而已~？

还有一个问题，就是prep里面待商榷的东东：介词+when~~~这种结构一出现就错？？？
