这道题看过讨论,但从没涉及一个我将要提的很弱的问题。。。 100. 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 我想说,中学好像说过英语里两个句子之间一定要有关系连接词,否则不能用逗号。那么题目中The stars are in motions, some of them at...speeds...这样的两个句子可以直接用逗号连接么,先不考虑其它因素,难道不应该是some of which at ...speeds才对吗? 可能是我基础语法有问题。。。谢谢解答。
