其中关于BD的解释中有这么一句话“and前后时态不一致，不应该省略后面的be动词”是什么意思？ 谢谢啊 作者: 翁羽凌虚 时间: 2011-2-10 21:05
嗯 还有一个问题顺便问一下 如果句子用主动语态是不是一定要有明确的动作执行者，如果动作执行者不明确才可以用被动语态？作者: hyyyyyy 时间: 2011-2-10 21:14
这个题选e吗？ be dated at和be dated to应该是固定搭配吧作者: 翁羽凌虚 时间: 2011-2-10 21:22
嗯 是选E的，be dated at和be dated to有一点区别： be dated at后面往往加的是xxxxyears old eg. be dated at 4,000 years old be dated to后面往往加的是具体的年份 eg.be dated to 1,000 years ago 不知道我说的清楚不？作者: 翁羽凌虚 时间: 2011-2-10 21:27
顺便再问一个 Caribou are wary animals with excellent hearing, so stalking them over the treeless landscape, getting close enough to kill it with nothing but a handheld lance, as Dorset people did, required exceptional hunting skill. B A. so stalking them over the treeless landscape, getting close enough to kill it B. so to stalk them over the treeless landscape and get close enough to kill one C. so in order to stalk them over the treeless landscape and get close enough to kill one D. and so in order to stalk it over the treeless landscape, getting close enough to kill it E. and so stalking them over the treeless landscape and getting close enough in order to kill it 对DE的解释是：and后半句没有主句，只有so引导的结果状语，其实and多余，应该删去； 为什么说and后半句没有主句类？不是后面是stalking them and getting close enough to .......required ......？我觉得这个挺完整的。。。。。为什么嘞？作者: hyyyyyy 时间: 2011-2-10 21:38
恩 挺清楚的 对于date at 和date to是考点吗？ 你一开始问的那个问题 and前后如果动词的时态是不一样的 是不可以省略的 如果and前后时态是一致的可以省 就是解释的那个意思 不知道表达的清楚不作者: hyyyyyy 时间: 2011-2-10 21:48
顺便问一个这个看晕了 我是因为it排除了ADE 然后分不出来了作者: 翁羽凌虚 时间: 2011-2-11 10:51
这个是考点的。嗯，挺清楚的，我明白啦 谢谢啊作者: 翁羽凌虚 时间: 2011-2-11 10:53
一般可以做主语的就是VING和to do，所以只能是to stalk them required...../stalking them required..... 而in order to do引导的是目的状语，所以不能做主语的作者: GmatMakeIt 时间: 2011-3-14 21:15

to do能做主语吗？作者: geegee 时间: 2011-3-14 21:23
这道题 OG上也有过，主要是 be dated at 这个表达，然后是动词用复数形式。
