Wildlife Crossing Bridges
The Wildlife Bridge
In 2018, Utah built a wildlife bridge over the busy highway 1-80. A 4.8-kilometer fence was created to help guide animals to the bridge. Normally, animals take a long time to discover and begin using wildlife bridges, so experts didn’t expect the bridge to get much traffic for several years. But recently, they’ve discovered many different kinds of animals are beginning to move by using the bridge.
The Rope Bridge
On China’s Hainan Island in 2015, scientists created a bridge for Hainan gibbons that are the world’s most endangered primates and normally cross the forest by swinging high in the trees. But after a 2014 typhoon, landslides caused huge gaps in the forest, which were forcing the gibbons to make dangerous jumps. Scientists created a simple and cheap rope bridge, which settled the problem.
The Eco-Bridge
In Uttarakhand state in India, the forest department has built a special "eco-bridge" , made from all-natural materials. It’s 27.5 meters long and runs over one of the busiest highways in the area. Though the bridge is high in the trees, forest department workers hope the bridge will help smaller animals on the ground, too. Already, the bridge has gotten a lot of attention on the Internet, with many people taking photos in front of it every day.
The Park Bridge
The Phil Hardberger Park lies in San Antonio, Texas, and recently it has opened what they say is the largest wildlife bridge in the US. This bridge, unlike the others mentioned here, was built for use by both animals and humans. The park says they have already seen deer using the bridge.

【1题详解】
细节理解题。根据The Wildlife Bridge部分中“Normally, animals take a long time to discover and begin using wildlife bridges, so experts didn’t expect the bridge to get much traffic for several years. But recently, they’ve discovered many different kinds of animals are beginning to move by using the bridge.(通常情况下，动物需要很长时间才能发现并开始使用野生动物桥，所以专家们预计这座桥在几年内不会有太多交通流量。但最近，他们发现许多不同种类的动物开始利用这座桥来移动)”可知，专家们对野生动物桥已经被动物使用感到意外。故选B。
【2题详解】
细节理解题。根据The Wildlife Bridge部分中“In 2018, Utah built a wildlife bridge over the busy highway 1-80.(2018年，犹他州在繁忙的1-80号高速公路上修建了一座野生动物桥)”以及The Eco-Bridge部分中“It’s 27.5 meters long and runs over one of the busiest highways in the area.(它长27.5米，横跨该地区最繁忙的高速公路之一)”可知，野生动物桥和生态桥横跨高速公路。故选A。
【3题详解】
细节理解题。根据The Wildlife Bridge部分中“A 4.8-kilometer fence was created to help guide animals to the bridge.(一道4.8公里长的围栏被用来引导动物们到桥上)”；The Rope Bridge部分中“But after a 2014 typhoon, landslides caused huge gaps in the forest, which were forcing the gibbons to make dangerous jumps. Scientists created a simple and cheap rope bridge, which settled the problem.(但2014年的台风过后，山体滑坡在森林中造成巨大缺口，迫使长臂猿做出危险的跳跃。科学家们发明了一种简单廉价的吊桥，解决了这个问题)”；The Eco-Bridge部分中“Though the bridge is high in the trees, forest department workers hope the bridge will help smaller animals on the ground, too. (尽管这座桥位于高高的树上，森林部门的工作人员希望这座桥也能帮助地面上的小动物)”以及The Park Bridge部分中“This bridge, unlike the others mentioned here, was built for use by both animals and humans. The park says they have already seen deer using the bridge.(这座桥不同于这里提到的其他桥，它既是供动物使用的，也是供人使用的。公园表示，他们已经看到鹿在桥上行走)”可知，建造这四座桥的共同目的是创建野生动物通道。故选D。
