8、ural Burn. It was acknowledged that some forest fires, such as those caused by lightning were necessary for forests to maintain balanced ecosystems, so the fire should be allowed to burn. However, a big fire in Yellowstone National Park in 1988 caused this policy to be abandoned since the fire was i

9、nitially allowed to burn yet soon out of control. As a result，the fire of 1988 destroyed much of Yellowstone, which is Americas 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 a

10、nd 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

11、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 vacati

12、on. Yellowstone had previously been famous for its amazing views and unique geological formations such as the geyser Old Faithful. But now its reputation as Americas 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。1Natural Burn was adopted b

16、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 are pollinators(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

17、 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 becau

18、se their work adds so much to our diet，” says Dr. Jeff Pettis of the Bee Research Laboratory.Californias 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

19、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 dont 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 b

20、e dead, replaced by new ones in the natural life cycle of bees. “It isnt like studying a large animal like a cow that doesnt 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 po

21、isons 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。但加利福尼亚的大量蜜蜂出现了不明原因的死亡，这引起了人们对重要粮食作物的担忧。4What is Paragraph

22、2 mainly about?A. The wind helps pollinate.B. Bees are important for food crops.C. Bees give us a lot of delicious honey.D. Cherry trees are pollinated by bees.答案B解析段落大意题。根据第二段的第二、四句可知，蜜蜂可以帮助植物授粉；在美国，养蜂人养的数百万只蜜蜂飞来飞去为粮食作物做着这种重要的授粉工作。因此选择B。5Bees are hard to study because _.A. they move around too much

23、 B. new bees soon replace all the bees studied by researchersC. they are too tinyD. they never return to hives答案A解析细节理解题。根据第四段中的“However, bees are hard to study. Most die away from the hive”及Pettis的话“It isnt like studying a large animal like a cow that doesnt move around much and is easy to find out

24、 in the cow field”可知，研究蜜蜂很难是因为它们活动得太多。6What could cause so many bees to die?A. Poisons to kill birds. B. Eating too much.C. Large insects. D. Some virus.答案D解析细节理解题。根据最后一段中的“A virus or bacteria could also be doing the killing”可知，某种病毒可能是蜜蜂大量死亡的原因，故选D；由最后一段中的“They could be sick because of poisons widel

25、y used to kill insects”可知，蜜蜂的死亡也可能是由可广泛用来杀死昆虫的毒药引起的，故A项说法不正确。7What can we learn from the article?A. A large number of bees have died in the hive.B. Without bees, some food would disappear from our diet.C. Only researchers in California want to know what kills bees.D. Large animals are more difficult

26、 to study than tiny insects.答案B解析推理判断题。根据第二、三段可知，某些植物须靠蜜蜂授粉才能结果，由此推知，如果没有蜜蜂给这些植物授粉，那么它们就不会结果，一些食物也就会从我们的饮食中消失了。故选B。三、完形填空Joe Simpson and Simon Yates were the first people to climb the West Face of the Siula Grande in the Andes mountains.
