24，Each year red-winged blackbirds stop in a certain region of Midland Province on their spring and fall migrations. In the fall, they eat a significant portion of the province's sunflower crop. This year Midland farmers sought permits to set out small amounts of posioned rice during the blackbirds' spring stop in order to reduce the fall blackbird poplution. Some residents voiced concern that the rice could threaten certain species of rare migratory birds. Nevertheless, the wildlife agency approved the permits.
Which of the following, if true, most helps to justify the widlife agency's approved of the permits, given the conerns voiced by some residents?
A .In the region where the red-winged blackbirds stop, they are the first birds to be present in the spring.
B The poison that farmers want to use does not koll birds but rather makes them incapable of producing viable eggs.
C. Since rice is not raised in Midland Province, few species of birds native to the province normally eat rice.
D .Without the permit, any farmers shown to have set out poison for the blackbirds would be heavily fined.
E. The posion that farmers got approval to use has no tast or smell that would make it detectable by birds.
ans:A
mine:C
请帮忙解释一下，我觉得C更有道理，文章给出的rare migratory birds.,这样的话，他们是最先出现在春天的不能保证它们一定在其他出现之前已经全部把poison吃完了。
c说birds not raised in Midland Province 也就是rare migratory birds，不吃rice，不是很对么？

在A和B中犹豫了很久。
我也是觉得A选项添加了一个条件，就是一定要吃光！但是不一定会吃光啊！
所以，我选了B..... 觉得至少没有杀死这些鸟，就不是threat， 而且这些red birth不能生好蛋，那么其population肯定比能生好蛋要少，所以在秋天来的鸟的数量就会减少了。
为什么B不对啊？

rare migratory birds的意思是珍稀候鸟，不等于birds native to the province
楼主大概理解错了
也不是nn：
这道题太可恨了，C是多么好的一个解释啊，却在分类上让人误解，可恨！
只好选A，很牵强。
题目中说，因为这种米对红黑鸟和珍稀鸟都有影响（threaten），所以不应该用，但是野生组织却批准了，那么B中的说不能杀死它，只是让它们不能在产蛋，这样还是会threaten,没办法解释为什么threaten还是批准。
作者: fatlara 时间: 2005-9-14 15:39
觉得B不对~~~~poison也会让residents想保护的rare migratory birds不能生育阿~~这样的议案当然不能被通过了。
嗯，我偏向于C，因为A还需要一个假设条件：the red-winged blackbird吃光所有的rice。。。。
但是，如果rare migratory birds的意思如2楼所说，是珍稀候鸟，不等于c里面的birds native to the province。。。。C就不对了。。。只能选错的不太离谱的A。。。。。虽然偶做题的时候选的C。。。

rare migratory birds 确实是"珍稀候鸟"
答案应是A.
作者: puccamummy 时间: 2005-10-21 23:56
我原来选C，仔细看了一下，还是选A.
C只说本地的鸟类很少吃rice。但这没用，对于migratory bird来说，可能它们吃rice，所以还是有可能毒到他们。
A选项：虽然最早一批到达不见得吃光毒大米，但是看原题——small amounts of——所以说明要毒只能毒部分的red－winged，让他们fall再回来的时候没那么多数量而已；米早就吃光，更别提别被别的鸟吃了。
作者: z520m 时间: 2005-10-28 16:02

作者: scorp_w 时间: 2005-10-28 18:30
red-winged blackbird 也是一种候鸟！撒了毒米后，因为red-winged blackbird 每年是第一批迁徙到这里的，所以他们会把这些米吃光，而不会影响到其他候鸟！
c我开始也选错了！我是读得不认真，先入为主的以为毒米影响的是本地的常驻鸟类！但不是这样的！

rare migratory bird 應該是指留鳥。也就是說這些鳥是不走的。不管red-winged blackbird是不是第一個到達的候鳥﹐rare migratory bird都已經在當地了。所以這些留鳥是可能第一個吃米的。當地人關心的是毒米會不會影響這些留鳥。所以C指明這些留鳥不吃毒米。應是正確答案。

作者: lvqingling 时间: 2007-4-4 19:32
为什么没有人选择E:
E. The poison that farmers got approval to use has no taste or smell that would make it detectable by birds.
E说明这种毒药根本不会被鸟吃到，因为它的气味和口味根本不会被鸟发觉； 批准了也没关系，毒不死鸟，又能安抚群众。
作者: znlhy 时间: 2007-4-27 00:18
楼上：注意题目中问的是“given the concern voiced by some residents”，要根据群众的关注点来。这道题里面焦点是两类鸟，E没有比较的含义，排除。
我还有一个问题，是不是加强题只需要加强而不需要完全使题目的逻辑充分？如果是的话，即使A选项没有说那些鸟会把毒米吃光，因为A能加强结论，所以不影响A成为正确答案？
期待NN回答~~
作者: guoguo463 时间: 2007-7-8 18:34
这个题目是中B.C是ETS最喜欢玩的把戏.
从B中我们可以得出规律:不增加不见得会减少
从C中我们得出:本地的鸟不吃,不见得外地的鸟就不吃,不能这样延伸.
A中说,RW来的最早,又因为RICE的数量少,他们就可能把RICE给吃光了，所以RICE就不会伤害到珍惜候鸟.
作者: fengyun158 时间: 2007-7-25 21:56
这个题目要理解结论的特殊性，to set out small amounts of poisoned rice during the blackbirds’ spring stop in order to reduce the fall blackbird population
既然是减少blackbird population，B和C显然对所有的鸟都有影响，所以不对。

Rare Migratory Birds Flock to Chinese Lake
Large flocks of rare migratory birds from north China and Siberia have been arriving at Poyang Lake in east China's Jiangxi Province this week to spend the winter.
Sources with the state-level Poyang Lake Nature Reserve said the number of birds is increasing rapidly.
According to the sources, these birds include white cranes, grey cranes, swans and many other rare species ......

如果rare migratory birds 包括red-winged blackbird(从题干中我们判断不出来是否包括,因为用的是certain而不是other),那么,如果选A的话,还是不能消除一些居民的CONCERN,因为 blackbird吃了毒药后数量就有可能被threaten.
当然B也不是好答案,C无关,因为native和migratory birds 正好相对.

在A与B之间痛苦抉择了半天，根据题目说的given the concern voiced by some residents,意思是也该考虑一些居民的感受，而这些居民认为毒米会对稀有鸟类构成威胁，A中说候鸟是春天第一批来的鸟，所以毒米会被他们吃掉从而不会对稀有鸟类构成威胁，所以the wildlife agency approved the permits.而B考虑的是farmer的感受，而不是居民的感受，所以还得先看清题意才是最重要的！妈妈呀，真要命。。。

其他论坛的解释
A strengthener with a twist: we have to take an objection into account.
Our prediction: an answer that suggests that the rare species will NOT be harmed by the poison.
Only (a) gives us any reason to believe that the poison will keep the blackbirds under control but won't hurt other species. If the blackbirds get there first, then we postulate that either:
- the blackbirds eat all the poisoned rice, so other birds aren't affected; or
- once the blackbirds are gone, the farmers can remove the poisoned rice, so other birds aren't affected.
Remember: "strengthen" is NOT synonomous with "prove". (a) certainly doesn't prove that other birds won't be affected, but it gives us a reason to believe that they won't be.
(b) through (e) don't distinguish between blackbirds and other birds, so they're all outside the scope.
