(A)In a previous design, the weight of the discus used in track competition is concentrated in a metal center, but now it is
(B)According to a previous design, the weight of the discus used in track competition was concentrated in a metal center, but now it is
(C)Once designed with its weight concentrated in a metal center, the discus used in track competition is now
(D)The discus used in track competition, once designed with its weight concentrated in a metal center, but now
(E)The discus used in track competition was once designed having its weight concentrated in a metal center and now
答案为C，OG的各项解释我也明白，我的问题是，假设有这样一个选项
(F) The discus used in track competition was once designed with its weight concentrated in a metal center, but now it is
谢谢您的回答，从OG的解释来看，我一直觉得GMAT的首选是并列句呢, 我想再问下，如果（F）选项存在，也是成立的是么？有没有关于【SVO, and SVO, ing从句】这种结构存在的例子，我想再体会下，万分感谢您了！！！作者: HarrisZheng 时间: 2011-12-8 21:57
首先, 你要搞清楚一个概念. 复合句比简单句并列简洁 几个不能算是原则的参照吧: 复合句比简单句堆叠简洁 如 I have a dog, and he likes to go out for a walk. 就不如I have a dog that likes to go out for a walk.
短语比从句简洁 如 My dog likes to go out for a walk when he finishes dinner. 不如，分词结构 Finishing dinner, my dog likes to go out for a walk. 或者 独立主格 Dinner finished，my dog likes to go out for a walk
F 选项语法没错 但没有C选项好作者: zoexixi 时间: 2011-12-8 22:06
