As a result，the fire of 1988 destroyed much of Yellowstone, which is America's oldest and most beloved national park. Massive areas of plants were destroyed, and large empty spaces and acres of burned and blackened trees greeted visitors. The rivers and streams were choked with ash, and the ecosystem of the park was changed beyond repair.In addition, great numbers of animals were killed by the fires that burned out of control. The fires were driven by high winds, moving as many as ten miles a day. Many small animals died in the flames. The fire's rapid advances gave the wildlife little chance to escape. Even today, few of these small forest animals have returned to live in the park. In the years immediately following the fires, the numbers of visitors declined rapidly. No one was interested in seeing a blackened and treeless park on vacatio n.Yellowstone had previously been famous for its amazing views and unique geological formations such as the geyser Old Faithful. But now its reputation as America's wonder is damaged permanently.1988年黄石国家公园根据1972年制定的政策允许焚烧森林，但由于风势太大，导致森林大火无法控制，许多动植物都被烧死了，黄石国家公园也不再是热门的游览地。

B（2015·安徽联考）All across California, honeybees are flying away from their hives (蜂箱) and dying. Empty hives are causing a lot of worry about some important food crops.Bees give us a lot more than delicious honey. They arepollinators(授粉昆虫)—they enable plants to produce the fruits and nuts we enjoy by carrying pollen from one plant or flower to the next. The wind pollinates oats, corn, and wheat, but many other plants (like apple and cherry trees and melon vines) depend on insects, bats, and birds. In the U. S．，millions and millions of bees kept by human beekeepers fly around doing a lot of this important work for food crops.“Bees are worth protecting because their work adds so much to our diet，”says Dr. Jeff Pettis of the Bee Research Laboratory.California's almond crop alone depends on about half the bees in the country. But now the almond crop and many others could be in trouble with so many bees dying.Researchers at government and university labs all over the country are trying to figure out why so many bees are dying. However, bees are hard to study. Most die away from the hive, so researchers don't have dead bodies to examine. And when researchers return to a hive after two weeks, about half the bees they studied on their first visit will be dead, replaced by new ones in the natural life cycle of bees. “It isn't like studying a large animal like a cow that doesn't move around much and is easy to find out in the cow field，”says Pettis.Researchers have some ideas about what could be affecting bees' health. They could be sick because of poisons widely used to kill insects, or they might not be getting enough good food to stay strong. Also, tiny insects called mites feed on bees. “A virus or bacteria could also be doing the killing，”explains Pettis.蜜蜂除了提供蜂蜜之外，还帮助植物授粉，它们是人类的益友。
