Question

【題目】A

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 which were caused by lighthing were necessary for forests to maintain(保持)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 abandbned since the fire was initially（最初）allowed to burn yet soon out of contro1．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 fires’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(噴泉) Old Faithful．But now its reputation as America's wonder is damaged permanently．
