The stars, some of them at tremendous speeds, are in motion just as the planets are, yet being so far away from Earth that their apparent positions in the sky do not change enough for their movement to be observed during a single human lifetime. (A) The stars, some of them at tremendous speeds, are in motion just as the planets are, yet being (B) Like the planets, the stars are in motion, some of them at tremendous speeds, but they are (C) Although like the planets the stars are in motion, some of them at tremendous speeds, yet (D) As the planets, the stars are in motion, some of them at tremendous speeds, but they are (E) The stars are in motion like the planets, some of which at tremendous speeds are in motion but
答案B 问题1: 答案B中，some of them at tremendous speeds 做什么成分？ 是独立主格做状语吗？ 问题2：og对于A选项的解释：placement of modifying phrase and the comparison are awkward and ineffective。。。说A选项中的 some of them at tremendous speeds应该放在motion后，这样才清晰。。 我不明白为什么~直接没看懂这段解释、、
恳请NN们解答。作者: arish 时间: 2011-4-2 00:52
some of them at tremendous speeds补充说明stars吧，应该算是独立主格吧，A里的being比较多余吧作者: cdy1234567 时间: 2011-4-2 02:25
拆呗，去掉同位语（some of them at tremendous speeds),得到两句话 ==>The stars are in motion just as the planets are ==>The stars (yet) being so far away from Earth that.... 这句话既充当主句又好似同位语修饰stars(being so far away)...就导致句子整体结构混乱。作者: jianglindenise 时间: 2011-5-23 20:03

引用：FactOrFiction NN 不是同位语. 同位语在逻辑含义上是可以互换的. 这里的some of 决定了不能互换, 因为范围不对.
