※ 引述《yuanyen100 (2009 is a big year!!)》之铭言： : Each year red-winged blackbirds stop in a certain region of Midland Province : on their spring and fall migration. 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 poisoned rice during the blackbirds’ : spring stop in order to reduce the fall blackbird population. 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 wildlife agency’s : approval of the permits, given the concern 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. : (C)Since rice is not raised in midland province, few species of birds native to : the province normally eat rice. : 答案是A我选C 实在看不出来A哪里对 请大家帮帮忙 :P 题目说明每年春秋,红赤黑鸟都会飞来M 然後秋天就会吃sunflower crop 所以农夫打算用毒米毒牠们 虽然有反对说这样会伤到某种别的候鸟 但是还是通过了这方案 A选项说明了这黑鸟春天会第一个先现身 所以他们会先吃完毒米 其他候鸟也吃不到 所以不会伤到其他候鸟 支持了这方案的可行 C错误是说native bird不太会吃这米 但是题干说明的是threaten certain species of rare migratory birds 和native birds是没有关系的 欢迎讨论 --
