A .In the region where the red-winged blackbirds stop, they are the first birds to be present in the spring.
这个选项莫名奇妙,说balckbird先来,难道说blackbird正好在别的鸟来之前把rice吃光了?也太自觉了吧?
感觉着道题怪怪的
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?
请NN指教!

I'd like to support B and C... But I really do not understand why to choose A.
It is easy to understand the context of argument, but the chooses are too confuse to choose. what is critical point or direction needed to solve this question?
who can explain why A is better than B and C??
NN help!!!
和11楼一样的问题
呼唤NN~~~
not NN
B可能导致其他鸟数量减少,没有把red-winged blackbirdd和其他鸟区分开
大家讨论
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。
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。。。
汗~~~~~呼唤nn出来解释一下rare migratory birds是个什么意思~~~
think the answer is A
the birds will eat a signifantly amount of sunflowers..but the farmers are only placed a small amount of poisoned rice..
if those birds arrive first..it's very likely that they will finish the small amount of rice (因為她們食量大!)
有道理~~~~~~~这样说来A很合理了
还是想知道c里面的rare migratory birds应该怎么理解~~~~
make sense!
