在过去上百年里，美国西部的灰狼被猎杀殆尽；而现在关于灰狼的问题就是灰狼是否已经恢复到了足够多的数量，人们又能够对灰狼重开杀戒了。

At issue is whether wolves, which were heavily hunted in the U.S. west for many decades, have recovered in Numbers enough to allow hunters to target them again.

比如，灰狼在西部大湖地区一般会在二月到三月繁殖后代而在北极的灰狼会晚上几个星期-一般是三月到四月。

For example, gray wolves in the Western Great Lakes region breed in February to March, while gray wolves in the arctic may breed a few weeks later - in March to April.
