答案是D米有问题. 想问的是 ：
这个that 指代的是什么呢？是不是前面的lights?
但是gmat又说同一句话中的同一个代词指代的东西要一致，而后面那个 that 指代的是“the amount of energy ”，怎么办啊？ 作者: larrylw 时间: 2011-11-14 21:43
指代equipment作者: hz032478 时间: 2011-11-15 20:17
前面的that是引导定语从句，修饰的是前面的equipment，such as light是插入语，后面的that是代词，修饰the amount of energy，两个that词性不一样作者: hbjat1989 时间: 2011-11-16 20:29
