标题: GWD17-Q11的想法
Some species of Arctic birds are threatened by recent sharp increases in the population of snow geese, which breed in the Arctic and are displacing birds of less vigorous species.  Although snow geese are a popular quarry for hunters in the southern regions where they winter, the hunting season ends if and when hunting has reduced the population by five percent, according to official estimates.  Clearly, dropping this restriction would allow the other species to recover.

Which of the following, if true, most seriously undermines the argument?

A.    Hunting limits for snow geese were imposed many years ago in response to a sharp decline in the population of snow geese.
B.    It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date.
C.    The number of snow geese taken by hunters each year has grown every year for several years.
D.    As their population has increased, snow geese have recolonized wintering grounds that they had not used for several seasons.
E.    In the snow goose’s winter habitats, the goose faces no significant natural predation.

关系1:雪雁抑制其他动物。关系2:猎人抑制雪雁。
条件:为了让雪雁不能抑制其他动物,就要加强猎人对雪雁的抑制(取消对猎人捕猎的限制)
削弱:限制没有效果过(猎人从来没有抑制过雪雁)

问题:这个restriction既包括5%的限制,还包括时间的限制
B说:在时限前停止捕猎,两个可能,两种结果:
可能1:猎人1天(夸张了点)就杀了5%的雪雁,导致捕猎提前结束,(restriction 有用)
可能2:猎人对杀雪雁兴趣不大,打了1天雪雁后,新鲜劲过去了,不打了。(restriction没用)

结论,这题没出好,出题人,想制造点难度,所以把话往含蓄了说,结果偷鸡不成蚀把米。

以上为GWD17-Q11的想法

今天刚跟人讨论完这题,如果单纯从应试角度来看的话,在结论中把原因复述了一遍,clearly,dropping this restriction ...那么,直接在选项里面找针对于restriction的论述即可。非常清晰。

补充说一些心得,要是在结论里面没有“啰嗦”这么一句原因的话,还得往前面一句转折句里面找原因,要是题干里面一直都是顺着说下来的话,那么答案应该就会在第一句引出话题的部分,一般来说找出范围就能锁定答案。难一点的题目则是在锁定的范围之外再延伸把表达变得模糊了一些,呵呵。
