og12 sc71：which、it指代？？

lenghong

[size=undefined]71.Unliketheoriginal 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 activatesthe animated functions of the piece.

(A)exhibit, which thereby activates             which不能带exhibit吗？还是因为语义或逻辑上有问题？

(B)exhibit, in turn an activation of            如果activation是 同位语呢？

(C)exhibit, and it will activate                it从逻辑上应该指 Project？？但实际从语法上可以指exhibit吗？

(D)exhibit and thereby activate

(E)exhibit which, as a result, activates

which it解释中说没有agent？？？是逻辑上米有吧？仅从语法角度，是有指代的吧？

请nn帮忙！！

for A, which 指代exhibit, 而exhibit自己是不能activate   的。A out
for B, awkward. 至于你说的同位语，那就更不可能。因为activation做同位语，那exhibit就是activation了，更说不过去。youknow，同位语是具有解释性的，他的antecedent必须和它相对应。
for C ，it 在语法上指代 Virtual Leonardo Project, （it 是完全指代）但你想，你都问了可以指代“exhibit吗？那就说明这个”it"有指代不清之嫌。out
for D, i think this is a CORRECT answer, since the subject of "activate" should be "visitors ",therefor we use plural verb form "activate",if you used "activates" ,the subject would be "project "rather tan "vistor", and" to touch" is parallel with " (to) activate"
E吧，它和A本质上是犯了一样的错误。
依我看，楼主是没搞清楚句子本身想要具体表达谁“activate" ， 也就是对句子逻辑把我的不清楚。
hope it helps

谢谢啊，解释的很清楚啊！！！

还想确认一下，同位语是不是必须紧跟要解释的名词啊？
比如：主语谓语宾语，同位语。。。同位语肯定解释宾语。
         但如果宾语是个短语呢？同位语是针对宾语的中心词？


不好意思啊，有点晕，望nn帮忙！

为什么A选项的which不可以指代整个句子呢？
