Tur- tles hide in their shells, and skunks release a smelly liquid. But these natural defenses do not work against cars. Environmental writer Ben Goldfarb explains, “When facing a car, these protections are useless—or even make things worse. Staying still is the most dangerous choice. Roadkill is a major danger to wildlife.” 　　Roads also act as barriers, limiting animals' freedom to move. The steady flow of traffic on highways creates what experts call a “moving fence”—one that animals are afraid to cross. While we often see dead animals like deer or squirrels on the road, we don't see the ones that never attempt to cross. This separation 第1讲　描述运动的基本概念 can harm animal groups more than roadkill itself. 　　Chemicals from roads also harm the environment. Every year, the U.S. uses 20 million tons of road salt to melt ice, which pollutes nearby soil and plants. Cars release metals like zinc and copper, and tires leave microplastics behind. These pollutants make roadside areas unsafe for species such as monarch butterflies, even though these zones could otherwise offer useful habitats. 　　Roadsides sometimes attract animals with food sources like flowers or fruits, but this becomes an “e- cological trap”. Animals come for the food, only to face the risk of being hit by cars. 　　Interestingly, when traffic decreases, animals adapt quickly. Researchers in the Bay Area found that when cars were absent for months, white-crowned sparrows—a type of small songbird—began singing more complex and varied songs. Without traffic noise, they no longer needed to “shout” and could return to their natural way of communicating. This shows how deeply roads affect wildlife—but also how flexible an- 第1讲　描述运动的基本概念 imals can be. Despite these challenges, Goldfarb points out that some species have learned to cope in remarkable ways. He mentions that urban foxes in Chicago are said to look both ways before crossing the street. “We often think roads only harmful to animals, and it's true that they cause a lot of damage,” he says. “But wildlife is also surprisingly adaptive and smart. Animals are finding ways to survive in a human-dominated world.” 第1讲　描述运动的基本概念 语篇解读　文章主要介绍了道路对野生动物的多方面影响,包括直接的身体伤害、活动范围的限制、 环境污染以及路边食物构成的生态陷阱等问题,同时也提到了一些动物对道路环境的适应行为。 第1讲　描述运动的基本概念 1.How does the writer begin this article? A.By giving examples. B.By telling a story. C.By explaining a term. D.By using numbers. 1.A　细节理解题。根据第一段中的“Turtles hide in their shells, and skunks release a smelly liquid. But these natural defenses do not work against cars.”可知,作者通过举例子来引入主题,动物的这些天 然的防御方法对汽车不起作用,路杀是野生动物面临的一大危险。故选A。 第1讲　描述运动的基本概念 2.According to the text, what harmful effect do roads have on animals? A.Less food to eat. B.Less freedom to move. C.Fewer animal habitats. D.More endangered animal species. 2.B　细节理解题。根据第二段中的“Roads also act as barriers, limiting animals' freedom to move.” 可知,道路对动物的有害影响之一是限制了它们的行动自由。故选B。 第1讲　描述运动的基本概念 3.What can we learn from Goldfarb's words in the last paragraph? A.City foxes rarely get hit by cars. B.Roads are not really bad for wildlife. C.Animals are smart in dealing with roads. D.We should pay more attention to protecting wildlife. 3.C　细节理解题。根据最后一段中Goldfarb说的话“But wildlife is also surprisingly adaptive and smart. Animals are finding ways to survive in a human-dominated world.”可知,动物在应对道路带来 的挑战时表现得很聪明,能够找到生存的方法。故选C。 第1讲　描述运动的基本概念 4.Why did the writer write this article? A.To ask people to reduce traffic. B.To explain how roads affect wildlife. C.To remind us that roadkill is very dangerous. D.To teach people how to protect different animals. 第1讲　描述运动的基本概念   根据上面的文章结构可知,本文主要介绍了道路对野生动物的多方面影响,包括直接的身体伤害、活动 范围的限制、环境污染、路边食物构成的生态陷阱等问题,同时也提到了动物的适应能力。故选B。 4.B　推理判断题。 第1讲　描述运动的基本概念 【高频词汇】    1.release v.释放;发行    2.act as 充当;担任    3.attempt v.试图;尝试    4.decrease v.减少;降 低    5.remarkable adj.非凡的;引人注目的 【熟词生义】　still熟义:adv.仍然;还是　生义:adj.不动的;静止的 【差距词汇】    1.evolution n.进化;演变    2.predator n.捕食性动物    3.roadkill n.路杀(汽车在公路上撞 死动物) 4.microplastics n.微塑料    5.pollutant n.污染物 第1讲　描述运动的基本概念 第1讲　描述运动的基本概念 Ⅱ.七选五   [2025河南新乡月考] 　　As our human population and resource needs grow, we are leaving less and less room for wildlife.
