T-3-Q24. （答案是A，不明白，请NN帮忙给看看，非常感谢~~）
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.
B.
The poison that farmers want to use does not kill birds but rather make 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 poison that farmers got approval to use has no taste or smell that would make it detectable by birds. 作者: waixiaoxi 时间: 2010-8-13 21:29

A. In the region where the red-winged blackbirds stop, they are the first birds to be present in the spring.(A 在我看来比较勉强，但可以理解为他们first到达，所以一定程度上把那些有毒的吃了，后来的稀有的迁徙鸟受害程度相对减小）
B. The poison that farmers want to use does not kill birds but rather make them incapable of producing viable eggs.（不能生蛋一定程度上造成了损害，错）
C. Since rice is not raised in midland province, few species of birds native to the province normally eat rice.(无关，native无关）
D. Without the permit, any farmers shown to have set out poison for the blackbirds would be heavily fined（和farmer怎么样无关）
E. The poison that farmers got approval to use has no taste or smell that would make it detectable by birds.(更加大了对鸟类的威胁，错）作者: miachw901304 时间: 2010-8-14 08:14
同意A
因为说的是small amount of poisoned rice嘛 所以他们先来就把这些有毒的吃光光了。其他鸟儿来的时候就莫有了
B
导致他们不能生蛋----可能会threaten to rare migitary birds 因此B 错
C D E 都无关。。作者: gmatmba 时间: 2010-8-14 22:06
