Lacking information about energy use, people tend to overestimate the amount of energy used
by equipment, such as lights, that are visible and must be turned on and off and underestimate that
used by unobtrusive equipment, such as water heaters.
(A) equipment, such as lights, that are visible and must be turned on and off and underestimate
that
(B) equipment, such as lights, that are visible and must be turned on and off and underestimate
it when
(C) equipment, such as lights, that is visible and must be turned on and off and underestimate it
when
(D) visible equipment, such as lights, that must be turned on and off and underestimate that
(E) visible equipment, such as lights, that must be turned on and off and underestimate it when
答案为D。它的解释是 :
that 引导的应是限制性定语从句,必须紧紧跟在所修饰名词,前面没有名词和介词以及逗号。所以ABC错。
求问~D和E中的第一个that不也是修饰lights且前面有逗号的么?这D和E的不也是错的么?
希望大牛以及各位路人指点~谢谢

此题用排除法更好。
首先BCE因为后半句用的是“underestimate it when”,错误,排除.
剩下AD, 再来分析句子。 LZ说得不错,that 引导的是限制性定语从句,必须紧紧跟在所修饰名词之后,但要注意,该题that前面的逗号不是用来分隔equipment和that的,而是插入语such as lights前后必须用逗号隔开,但这并不影响that修饰前面的“equipment”,因为去掉插入语(包括前后两逗号)后,that就紧跟在equipment后面了,并没有逗号隔开。
再从句子的简洁性来说,A过于啰嗦,可以用一个形容词修饰的却用一个定语从句,明显D更好
另外,再看后半句的“by unobtrusive equipment”,则D中by visible equipment和其对应,句子结构也更好。

不知道lz这个是哪里的解释。that引导限制性定语从句修饰equipment,A和B用are,主谓不一致,错误。c中that is visible繁冗,可以直接用visible形容词,这个gmat规则里有提到过。c和e后面it指代错误应该是that代替前面同类名词the amount of energy。when也用错了,应该是that和前面平行。
