　　By the closing decades of the 19th century, the hardwood forests where passenger pigeons nested had been damaged by American’s need for wood, which scattered (驱散) the flocks and forced the birds to go farther north, where cold temperatures and spring storms contributed to their decline.Soon the great flocks were gone, never to be seen again.

　　In 1897, the state of Michigan passed a law prohibiting the killing of passenger pigeons, but by then, no sizable flocks had been seen in the state for 10 years.The last confirmed wild pigeon in the United States was shot by a boy in Pike County, Ohio, in 1990.For a time, a few birds survived under human care.The last of them, known affectionately as Martha, died at the Cincinnati Zoological Garden on September 1, 1914..

　　最后一段开头指出了一部法律的颁布，通常法律的颁布是好的结果，但是本文给出的结果却事与愿违。因此需要考虑作者点出颁布法律这件事的意图。
