做题时，认为which的指代有问题，只指代spacecraft，但是首先spacecraft和shuttle是并列关系，可以看做一个整体，其次which were指出不是单数名词，那么可以是指代二者。

unlike the shuttle和space station可比，which引导的定语从句修饰spacecraft能够带足够的燃料for 表目的，for their short flight。 先读懂整句话的在说什么意思。其他错误选项错在比较对象，修饰语，语义重复，

a space station 和前面的两个名词平行，但是a of b 就不平行了。

which在这里明显比with的使用表达要更加准确。

capable of doing 是没错的！！错的只有the ability fro doing sth

【做错】B的with放中间容易夹心修饰歧义，既可以修饰前面成分也可以修饰后面成分；sufficient和enough是重复啊wordy啊；另unlike要注意比较对象的对等，应当是the shuttle and earlier spacecraft和orbiting space station相比较

D选项which引导的定语从句可以修饰the shuttle and earlier spacecraft?正常来讲是修饰earlier spacecraft的吧？不会引起歧义吗？还是因为这里是which were，所以只能修饰the shuttle and earlier spacecraft？ 根据住谓一致，可以判断whici 修饰the shuttle and spacecraft.

which虽然按语法来讲是只能修饰就近的名词，但是因为这里后面是were所以表示修饰前面两个名词

注意看第二个句子，orbiting space station,所以要跟这个作比较

unlike 比较对象要平行， shuttle and spacecraft 与 space station 要平行对称
