标题: OG中的一道题目 [打印本页] 作者: xiaohai725 时间: 2010-12-3 14:45 标题: OG中的一道题目 不好意思啊!因为上次看到一个贴子版主说:“大家都有OG,就不用抄题了。”所以就没抄,现在把题补上,望大家见谅! 题目是:The widely accepted big bang theory holds that the universe began in an explosive instant ten to twenty billion years ago and has been expanding ever since. A. that the universe began in an explosive instant ten to twenty billion years ago and has been expanding B. that the universe had begun in an explosive instant ten to twenty billion years ago and had been expanding C. that the beginning of the universe was an explosive instant ten to twenty billion years ago that has expanded D. the beginning of the universe to have been an explosive instant ten to twenty billion years ago that is expanding E. the universe to have begun in an explosive instant ten to twenty billion years ago and has been expanding PS:我是今年九月份在新东方报的班,现在也只是对GMAT有个大致的了解,不过语法一直是我的弱项,所以报了班之后效果也不好,现在做题的时候还是很晕,有时候看到题都无从下手(也就是根本不知道考的哪个知识点),希望大家能给我提供点学语法的方法,本人在此先谢谢大家了!作者: xiaohai725 时间: 2010-12-3 14:58
这题我选的B,我觉得是考平行,and前后谓语不是需要时态一致吗作者: Jolinsysu 时间: 2010-12-3 15:41
和LZ开始一样,我第一次做的时候也选的B,不过经过这些天ETS的熏陶,尤其是它的logical predication,蕴含丰富啊,(神马时态、主被动关系,局部与整体的关系,人和物谁是主语的问题等等)。这一道题,首先that不可省,排除D、E,the universe爆炸在过去发生,一般而言,过去完成时是指对过去的过去有影响,而后一句提到,the universe还在(指现在也是)expanding, 所以,宇宙的爆发用一般过去时即可,不用这么复杂的表示过去完成时,同理,我们打字的这一刻宇宙还在爆发,现在完成时,表达过去(已爆发)对现在(还在expand)的影响。
