21. A proposal has been made to trim the horns from rhinoceroses to discourage poachers; the question is whether tourists will continue to visit game parks and see rhinoceroses after their horns are trimmed.
(A) whether tourists will continue to visit game parks and see rhinoceroses after their horns are
(B) whether tourists will continue to visit game parks to see one once their horns are
(C) whether tourists will continue to visit game parks to see rhinoceroses once the animals’ horns have been
(D) if tourists will continue to visit game parks and see rhinoceroses once the animals’ horns are
(E) if tourists will continue to visit game parks to see one after the animals’ horns have been

can't see any reason why A should be eliminated

21．排除选项：表示是否用whether，不用if，排除D，E
选项A：their指代有歧义，优先指代tourists
      see不知道和谁并列，动作目的用不定式表示
      时态有问题，应该是完成时，表示已经被割掉（角）
选项B：one无指代
      their指代有歧义，优先指代tourists
      时态有问题，应该是完成时，表示已经被割掉（角）
选项D：if错
      see不知道和谁并列，动作目的用不定式表示
时态有问题，应该是完成时，表示已经被割掉（角）
选项E：if错
      one无指代

Thanks, Dreadpower.
1, it's just a presupposition. how can u judge it's finished?
2, do visitors go to the game park just to see rhinos? or, they go there to see zebras, giraffes, ostritches, rhinos, etc?

Same question, how to justify the perfect tense? the activity has not happened yet!

同问

我认为，B还是应该靠one 和their排除。时态问题，除非有明确的提示词，如：since，不要轻易用作判断依据

boyray · 发表于 2005-8-1 17:25:00

但是如果是按就近指代，their不就是指代rhinoceroses吗，为何说指代不明呢？

还有，完成态是一定要用吗？还是都可以的？

icare1 · 发表于 2005-8-9 10:11:00

这个完成时确实有问题，OG中很多解释都是优先用事态进行判断的。

再讨论！

不明白after their horns are trimmed 和once the animals’ horns have been trimmed 有什么区别？

怎么说哪个好呢？

以下是引用dreadpower在2003-12-24 19:48:00的发言：

能否解释一下their优先指代tourists的理由？按照就近原则应该修饰rhinoceroses。难道代词都优先指代句子主语？好像gmat中代词前面如果有多个名词的话，og总会说ambiguous，难道gmat不认可就近原则？
