Starting in 1972，the National Park Service established a policy for forest fires called Natural 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 initially allowed to burn yet soon out of control. 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 vacation. 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.

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.(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, (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。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。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。________．ver return to hives
答案 A解析细节理解题。根据第四段中的“However, 及Pettis的话“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”可知研究蜜蜂很难是因为它们活动得太多。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 widely 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。ied 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 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

答案与解析 这是一篇记Joe Simpson和同伴Simon Yates成功攀登秘鲁境内安第斯山脉的Siula Grande峰返回途中的遭遇。 根据前句内容可知他们第一个爬上了秘鲁境内安第斯山脉6米的Siula Grande峰所以选C。 根据下文内容可知他们受了伤遇到了困难所以下山的路是很艰难的选A。 上文提到他们已经爬上山顶现在是在下山故答案选D。 Joe受伤了如果Simon不Joe，他会安然返回而且后文提到Simon决定冒险故答案选B。 在困难的情况下Simon带上受伤的同伴是在冒着生命的危险答案选D。C 从上文内容可知他们是在下山所以选C。 根据前面内容可知受伤就是一个麻烦事了所以天气的恶劣对他们来说是另一个麻烦选D。 由于恶劣的天气他们看不清楚也听不清楚因而Simon错误地把Joe用绳子放到了悬崖边答案选A。 因为Joe受了伤而又是在悬崖边所以对于Joe来说爬上来是不可能的也不可能下去救他选D。 从故事内容可知是在用绳子把Joe往山下送所以能影响到Simon的是Joe的重量选B。 根据语境判断坚持到最后不忍心放弃他的同伴答案选A。 根据下文内容可知他终于做出了放弃朋友的决定。 空前提到他割掉绳子所以Joe是摔了下去。 从下文可知Joe成功的爬回营地活了下来。 因为Joe受伤了所以是慢慢移动着。 此处指距离所以用away。 最后可知他回到营地了选D。 在那种情况下他以为Joe会死掉选A。 根据后文可知他又在那里呆了几天所以没立即回去。 从上文可知他没想到Joe会活着爬回来所以不相信。
