Question

    In the U. S. state of Washington, a road called Interstate(州际公路；州际的)90 cuts through a wild mountainous area to reach the city of Seattle. For the area's many kinds of animals, busy high- way greatly limits their movements. Animals need to move to find food, to find mates, to find new places to live as their populations expand or just when conditions change, like a fire breaks out. Crossing I-90 – as the road is called – is a risky but sometimes necessary act. But soon, animals will have a safer choice. They will be able to go above it.

To help the animals, the state is finishing work on its largest - ever wildlife bridge. The 11-meter-tall, 20 - meter - wide bridge begins in the forest. It forms two arches above the highway, one for each direction of traffic. Workers are adding fencing anti plants to help guide the animals across the bridge，Two-meter-thick walls will help block noise from vehicles below. Scientists chose the area because it is within a natural migration(迁徙)path for some animals.

The I -90 bridge is part of a growing number of wildlife crossings across the United States. Some are fences, some are overland bridges，and some are underpasses. They all aim to keep drivers and animals away from each other.

A U. S. Transportation Department study found crashes between animals and humans rose year by year. The accidents made up about 5 percent of all crashes nationally, and cost the economy (经济)about ＄ 8 billion. Such costs come from car repaid, emergency room visits and removal of the dead animals on roads. Collisions between animals and drivers are rarely deadly to people. But they are often deadly to wildlife. The study also found that 21 endangered or threatened species in the U.S. are affected by vehicle hits. Bridges, underpasses and fencing reduce I he area's animal - driver collisions by 80 percent.

Most of the wildlife bridges are in western states. Many other areas also need such paths. But finding money for more crossings is“the- number - one problem”. Patty Garvey — Darda of the U. S. Forest Service has worked on the I - 90 crossing from the start of the project. She says the $ 6 - million bridge will one day pay for itself because the highway will not have to be fully or partly closed each time a large animal is struck. “If you shut clown Interstate 90, you shut down interstate trade. ” she adds.

A. It goes from Washington D.C to Seattle,

B. It is dangerous for wild animals to cross.

A. Traffic accidents went down gradually nationwide.

B. Most money was spent in rescuing wild animals,

C. Collisions are more deadly to wildlife than to people,

D. Some species no longer existed because of vehicle hits.

4.Which of the statements may Patty Garvey - Darda agree with?

【解析】

本文为说明文。在美国的华盛顿州，一条名为“90号州际公路”的道路横穿一片野外山区，直达西雅图市。对于该地区的许多动物来说，这条川流不息的公路极大地限制了它们的活动。横穿90号州际公路（I-90）是一种冒险的行为，但有时候又不得不穿。然而，不久后，动物们过马路有了更安全的选择——从公路上方横穿。为了帮助这些动物们，华盛顿州正在完成有史以来最大的野生动物高架桥的建设工作。这条高架桥高11米、宽20米，始发点位于丛林中。高架桥在公路上方形成了2道拱门，每个方向各设一道。工人们正在架设围墙和植物，帮助引导动物过桥。围墙厚2米，将有助于隔绝下方车流的噪音。这些工程旨在让司机和动物“各行其道”。

1.细节理解题。根据第一段中的For the area's many kinds of animals, busy high- way greatly limits their movements.及Crossing I-90 as the road is called - is a risky but sometimes necessary act.可知，对于该地区的许多动物来说，这条川流不息的公路极大地限制了它们的活动。横穿90号州际公路是一种冒险的行为。由此可知，野生动物穿过90号州际公路是很危险的。故B选项正确。

2.细节理解题。根据第二段中的To help the animals, the state is finishing work on its largest - ever wildlife bridge.及第三段中的They all aim to keep drivers and animals away from each other.可知，为了帮助这些动物们，华盛顿州正在完成有史以来最大的野生动物高架桥的建设工作，这些工程旨在让司机和动物“各行其道”。故A选项正确。

3.推理判断题。根据倒数第二段中的Collisions between animals and drivers are rarely deadly to people. But they are often deadly to wildlife.可知，动物和司机之间的碰撞很少对人致命，但它们对野生动物往往是致命的。由此推知，碰撞对野生动物的危害比人类更大。故C选项正确。

4.推理判断题。根据倒数第一段中的She says the $ 6 - million bridge will one day pay for itself because the highway will not have to be fully or partly closed each time a large animal is struck可知，帕蒂·加维·德拉达认为这座耗资600万美元的桥梁早晚会彰显其价值，因为I-90不必再因为某只大型动物堵塞了交通而做完全或部分封锁了。由此推知，“建这座桥的努力会有回报的”符合帕蒂•加维•德拉达的观点。故C选项正确。
