OG-SC-71 疑惑中...

sullivan215

71.Unlike the original National Museum of Science and
Technology in Italy, where the models are encased in
glass or operated only by staff members, the Virtual
Leonardo Project, an online version of the museum,
encourages visitors to "touch" each exhibit, which
thereby activates the animated functions of the piece.

(A)exhibit, which thereby activates

(B)exhibit, in turn an activation of

(C)exhibit, and it will activate

(D)exhibit and thereby activate

(E)exhibit which, as a result, activates

答案是D，小弟想问一下这里有关“which”的用法，OG解释是“Which has no antecedent in the sentence, so it is unclear what activated the display.”
这里不可以是一个which引导的非限制性定语从句吗？which指代前句中一部分“encourages visitors to "touch" each exhibit” 可以吗？求赐教~~

自己先顶一下，还请高手赐教呀~谢谢！

我认为这个问题是这样的，which引导的关系从句，它所指代的先行项必须是个n性质的，可以是n、也可以是n性词组。而encourages是句子中的main verb，整个指代就没有n性质，而将each exhibit作为它的先行项又不合适，which在这里就没有先行项了。

根据句意啊。。。which 指代exhibit明显不符合逻辑，应该为前面的整个句子，所以错误，要选择D

嗯呀，谢谢大家的指教~想顺应GMAC的思维还真不容易呀...

语法上来说which指代exhibit没错，但是thereby的用法要求其之后的动作，与前面动作的发出者一致，此题中就是visitors。which thereby 的用法不好，应该是and thereby
