[求助]T-4-Q30(搜索过了,没有这个题目的讨论)

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

答案是D,可是B为什么不能选呢? 而且D里莫名其妙的出现了were capable of 这种表示"能够"的词语,而原文中并没有这个意思,属于意思改变;另外,使用短语不是比使用从句更加简洁有效吗?

正确答案D, 这里用 could 比较好，用 were capable of 也不能算错。

B 错在with 结构做定语，前面一般不用逗号。而且with 结构做定语不够FORMAL，不如定语从句好~

"B 错在with 结构做定语，前面一般不用逗号"

I don't agree with it. Anybody can explian? Thanks

想请教一下，D答案中定语从句的were怎么解释？

which指代复合结构 shuttle and earlier spacecraft，所以后面要用复数were

我考虑了这个问题，但前句是复数，后句是单数，WITH 里面有THEIR

很明确是修饰前句啊

不太认同
