请教ogsc中的第49题

hpp920

49. The cameras of the Voyager 2 spacecraft detected six small, previously unseen moons circling Uranus, which doubles to twelve the number of satellites now known as orbiting the distant planet.

a. which doubles to twelve the number of satellites now known as orbiting

b. doubling to twelve the number of satellites now known to orbit

c. Which doubles to twelve the number of satellites now known in orbit around

d. doubling to twelve the number of satellites now known as orbiting

e. which doubles to twelve the number of satellites now known that orbit

问题一:OGSC上说"The pronoun "which" should be used to refer to a previously mentioned noun, not to the idea expressed in an entire clause."但我记得无论中文还是英文的语法资料上都说which可作非限定性定语,修饰前面的整个句子.这里我感觉double的主语应该是前面的整句话所表达的意思,所以我做题是从a,c, e中选的,当然我是错的,但错在哪里?

问题二:OGSC上说"the participal form, "doubling", modifies the preceding clause."也就是说doubling的逻辑主语应该是前面的整个句子,这我同意.但我翻遍了张道真的书也没看见这种用法(只有现在分词做结果壮语和ETS的解释有点相似,但通常这种情况,主句的主语也可看做现在分词动作的发出者,).在我的知识里,doubling 处于这样的位置,camera就成了doubling 的发出者,但这于文中表达的意思不符,为什么用doubling?

谢谢!

首先, which 的用法在GMAT中和日常英语有出入.  GMAT认为这种说法unclear.  所以排除, a c e.  

问题二:OGSC上说"the participal form, "doubling", modifies the preceding clause."也就是说doubling的逻辑主语应该是前面的整个句子,这我同意.但我翻遍了张道真的书也没看见这种用法(只有现在分词做结果壮语和ETS的解释有点相似,但通常这种情况,主句的主语也可看做现在分词动作的发出者,).在我的知识里,doubling 处于这样的位置,camera就成了doubling 的发出者,但这于文中表达的意思不符,为什么用doubling?

这里是结果状语, 整个动作带来的结果. 而非单个主语.  这种例子在英文里面很多.  可能是你记错了吧.  不要紧, 多多读, 培养出语感就好了.

谢谢!

非常感谢你!想通了

又有一个新问题,还请这位高手再帮忙: 为什么用"known to orbit", 而不是"known as orbiting"?后者不更能表状态吗?

know后面加as,只能是know A as B (A,B均为名词,A可以是sb or sth),一般来说有3个意思：

1.用B来命名,或表明A.(B一般是一个"name")

2.A has B's qualities.

3.(在一定范围内）familar with A (像对B一样）
