标题: T-3-Q24

1. T-3-Q24.

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?

In the region where the red-winged blackbirds stop, they are the first birds to be present in the spring.
The poison that farmers want to use does not kill birds but rather make them incapable of producing viable eggs.
Since rice is not raised in midland province, few species of birds native to the province normally eat rice.
Without the permit, any farmers shown to have set out poison for the blackbirds would be heavily fined
The poison that farmers got approval to use has no taste or smell that would make it detectable by birds.

答案选A，C为何不对？

residents' concern is the rice could threaten certain species of rare migratory birds. Red-winged blackbirds are the first birds present in springthey .If they eat all the posisoned rice, afterwards, certain species of rare migratory birds won't be harmed.

请问为什么B不对呀？

作者: amumu 时间: 2009-8-31 16:16
rare migratory 不就是 native的意思吗？

A的问题是：如果没有吃完，其他鸟还是要遭殃啊！

rarely migratory birds 才是native birds，呵呵。查了字典。

rare migratory birds是“稀有的候鸟”，断句应该断成rare migratory birds
