标题: OG12 14求助 有关于状语从句省略的问题 [打印本页] 作者: 引夕 时间: 2011-7-13 02:18 标题: OG12 14求助 有关于状语从句省略的问题 Sunspots,vortices of gas associated with strong electromagnetic activity, are visible as dark spots on the surface of the Sun but have never been sighted on the Sun's poles or equator. C appear on the surface of the Sun as dark spots although never sighted at illustration for C:although typically introduces a subordinate clause, which has a subject and a verb, but here there is no subject and sighted is not a complete verb. 那为什么这里不能看成是状语从句的省略呢？ 看到说状语从句的省略要求一是谓语动词是be，二是逻辑主语是句子主语。那我觉得这里两点都符合呀？ 翻了之前的一些帖子也没明白……求教…… 作者: nemiah 时间: 2011-7-13 10:15
应该用被动，不能省略作者: 引夕 时间: 2011-7-13 10:18
那就是说被动的情况下就不能省略咯？作者: gmatbiguo 时间: 2011-7-13 10:25
在gmat中，although 必须引导从句，是从句就必须有主+谓的结构，该用法同以because /as引导的从句作者: 引夕 时间: 2011-7-13 10:44
我看新东方的那个OG题目解释里写“although引导的是完整句子，但要注意状语省略的情况”然后就是不太明白什么时候会发生状语省略的情况…………这题里的C为什么不能理解成这种情况？作者: qiuhua01234567 时间: 2011-7-13 11:27
省略情况一个是主语是it或和主句主语相同，且在谓语中含有be，省略从句的主语和be，这里是被动啊，省略了be 就感觉意思出错了，容易混淆，我个人感觉是这样。作者: nemiah 时间: 2011-7-13 11:30
我觉得这里应该不上have never been， 否则 sighted有修饰dark spots的嫌疑吧。。作者: sunsgiant 时间: 2011-10-22 23:48
原句用连词but连接are visible as dark spots on the surface of the Sun 和 have never been sighted on the Sun's poles or equator. 说明这是并列关系，是两个平行独立的句子。改成although+状语从句就把两个句子的关系改为主从关系。这属于改变句子的重心~~~~作者: deityc 时间: 2011-10-24 21:02
LS正解，我觉主要问题不是后面是不是句子的问题，而是重心变了作者: deityc 时间: 2011-10-24 22:30
刚说完，就看到个反例.....
