问题     The bombing campaign in Afghanistan has worsened the environmental disaster that was initiated by years of civil conflict and drought. The country’s remaining forests me being bombed or burned in the search for terrorists, and refugees me clearing forests for fanning and fuel. Afghanistan’s mountains— home to leopards (豹), bears, and Marco Polo sheep—were also at risk. Some refugees were reported to be hunting rare snow leopards to buy a safe passage across the border.
    In Tasmania 77 Australian species, including some that had been eliminated on the mainland, were potentially at risk after foxes were introduced, perhaps deliberately by individuals who wanted new game. Wildlife managers were trying to devise ways of killing the foxes without harming native species. A threat to native freshwater species in the eastern U.S. was feared when northern snakehead fish—a species that can survive out of water for several days mid travel over land—were found in a pond in Maryland. A local man evidently had released two of these fish, and they were breeding. In September Maryland wild life officials sprayed poison into the pond where the snakeheads had been found.
    On the Hawaiian island, an attempt to bring together a pair of the world’s rarest birds failed in May when the female bird, after being transferred to the territory of the only male, flew back to her own home range without encountering the male. There were only three surviving birds of this kind.
    Besides the upsetting stories, some good news may make people relieved. Efforts to save the kakapo—New Zealand’s giant ground-nesting parrot, met with more success. The last surviving birds, brought together on one island, produced 24 chicks, more than in the whole of the previous two decades. This brought the world total to 86 kakapo, compared with 50 in 1995.
    Obviously, the burden is heavy and the mad is long, so both the government and the public should pull together and fight for a more colorful and diverse world.
According to the passage, during the past twenty years, the kakapo ______.
选项 A、was almost extinct
B、was totally less than 24
C、had reached 24
D、bred powerlessly
答案D
解析 文章倒数第二段说到“新西兰的这种鹦鹉在一个岛上产下了24只幼雏，这比前20年产的幼雏总数还要多。”由此可以推断出在过去20年间，这种鹦鹉的繁殖很少，繁殖能力比较弱。因此，选项D是符合文章内容的。
