请教几道GMATPrep的语法题。各位战友多帮忙啊，谢过了！ 1. Since 1990 the global economy has grown more than it did during the 10000years from the beginning of agriculture to 1950. A. Since 1990 the global economy has grown more than it did during the 10000 years from the beginning of agriculture B. Since 1990 the growth of global economy has been more than that during 10000 years, from when agriculture began 本题答案为A。但是我不知道为什么B错。另外from后面，我觉得B选畋華选项好。有点迷糊了the beginning of agriculture 是指时间点么？ 2。The image of Stone Age People as systematic hunters of large animals, rather than___________, including three wood spears..... C. as mere meat scavengers, has emerged from examining tools found in Germany that includes D. mere scavengers of meet, has emerged from the examination of tools found in Germany, including 答案是D。答案是比较确定，但是对于这里examining tools和examination of tools的比较，确不是很懂。是不是这里from之后只能接名词呢？C的examining就成了修饰tools的？所以不对？ 3. The spectacular disintegration of a comet last year in full view of ground-and space-based tele三copes provided new insights into how comets form and may thus force a rethingking of..... A. The spectacular disintegration of a comet last year in full view of ground-and space-based telescopes provided new insights into how comets form and may thus force E. Last year, in full view of ground-as well as space-based telescopes, the spectacular disintegration of a comet has provided new insights into how comets form and may thus force 答案是A。本句话没有看懂。不懂这里last year在A中修饰什么？位置好奇怪。还有E除了那个as well as和has provided有问题之外，把last year放在句首有问题么？ 4。More than ten times as much as energy is________________in 1990. D. generated through wind power now as was the case E. now generated through wind power as it was 答案是D。可是我觉得E好整齐的对称阿。为何错误？it 要换成that? 还有我觉得now的位置，放在动词前面还是后面好？ 另外D这样的回答（as is/was the case) 在大全和OG上好像都没有见过：（ 另外GMATPrep的屏幕怎样可以拷贝下来？ |
