Unlike the short flights of the shuttle and earlier spacecraft, which carried sufficient power in fuel cells and batteries, a permanently orbiting space station will have to generate its own electricity.
Unlike the short flights of the shuttle and earlier spacecraft, which carried sufficient power in fuel cells and batteries, a permanently orbiting space station will have to generate its own electricity.
A. the short flights of the shuttle and earlier spacecraft, which carried sufficient power in fuel cells and batteries,
B. the shuttle and earlier spacecraft, with sufficient enough power in fuel cells and batteries for their short flights,
C. the short flights of the shuttle and earlier spacecraft, which enabled them to carry sufficient enough power in fuel cells and batteries,
D. the shuttle and earlier spacecraft, which were capable of carrying sufficient power in fuel cells and batteries for their short flights,
E. the flights of the shuttle and earlier spacecraft, whose shortness allowed them to carry sufficient power in fuel cells and batteries,
答案D,我选了个A。
A C E前半段 的错误是因为比较a permanently orbiting space station 太啰嗦吗? D后半段的which were capable of carrying sufficient 相比其他不是很啰嗦吗??? 求讲解,谢谢!
不是啰嗦的问题,主语是a permanently orbiting space station,划线部分是主语同位语,显然 flights不可能是station,所以只有D的the shuttle and earlier spacecraft才正确

谢谢楼上!
刚才又看了一遍:不是找到是不是这样 A. flights of the shuttle and spacecraft, B. (the shuttle and earlier) spacecraft, with sufficient enough power in fuel cells and batteries for their short flights, C. flights of the shuttle and spacecraft, D. (the shuttle and earlier) spacecraft, which were capable of carrying sufficient power in fuel cells and batteries for their short flights, E. flights of the shuttle and spacecraft,
