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.
B: the shuttle and earlier spacecraft, with sufficient enough power in fuel cells and batteries for their short flights
D the shuttle and earler spacecraft, which were capable of carrying sufficient power in fuel cells and batteries for their short flights.
在讨论区看到都是讨论B为什么不对的,我想问D里面的were为什么用复数?

不是的,enough对的你去大全里可以搜到好几个。
enough是个小错误,放到后面排除。(以前也有个帖子专门总结了下enough的)
PS:可能是没人做天山,都直接做GWD了...所以楼主的帖子就沉了,不要气馁啊...大家肯定没这意思的
