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 to 1950.
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.
答案选A,对于B中的that的用法我有点疑惑。
作为ron的脑残粉，我在manhattan的论坛上找到他这样一句话
you can't use 'that' in this sort of construction, because constructions using 'that of' (or other preposition after 'that') must have EXACTLY parallel structures. in other words, if the second half says 'that during 10,000 years', then the preceding half must say 'the growth of ___ during something else' (or some other time preposition, such as before or after, in place of during).
可是随即就有中国学生叫板
I assume that the rule applies to "those+preposition" in a comparison sentence (such as an "as...as" sentence and a "than" sentence)
I have read through all OG 10 SC questions, and it seems like that 2 of them are exceptions:
19. In addition to having more protein than wheat does, rice has protein of higher quality than that in wheat, with more of the amino acids essential to the human diet.
112. Domestic automobile manufacturers have invested millions of dollars in research to develop cars even more gasoline-efficient than those at present on the road.
(I know that I am not supposed to post OG questions because of the copyright issue; hope that it is okay to post without posting the full questions; otherwise, please delete my questions and leave the question #s so that other can refer to their OG books)
I believe that the "exactly parallal structures" refer to a pair of prepositional phrases serving the similar function. If my understanding is correct, then #19 is an exception to your rule.
In #112 "cars" isn't followed by preposition....
对此ron的解释是
in #112, "at present" isn't part of the parallel construction; it's an idiomatic expression with the same meaning as the word "now". i.e., you could write this as ...than those now on the road, and the meaning would stick. so that is a non-issue.
#19 is interesting. there's still LOGICAL parallelism - you have the protein contained in rice, and you have the protein contained in wheat - but the GRAMMATICAL parallelism isn't lock-step: you have "rice has protein" vs. "that in wheat". in other words, while both halves refer to the protein contained in a particular type of food, they do so in slightly different ways.
the lesson here is that we shouldn't complain, but, rather, we should learn: if the logical parallelism is absolutely clear, then the gmat will tolerate slight anomalies from the ideal of exact grammatical parallelism.
感觉对于这个知识点ron也不太解释的情啊，或者说有点底气不足
有NN知道这个that到底用的对吗？
呆呆要考试了，在此拜谢大家啊。。。
