The coyote(丛林狼)that clever animal of wide-open spaces,has come to the nation’s captial.In fact ,coyotes have spread to every corner of the United States,changing their behaviors to fit new environments and causing researchers to deal with a troublesome new kind of creature:the city coyote.
The coyote originally lived in the middle of the continent.One of its most obvious characters is its smartness, which has made the animal a notorious（臭名昭著的）pest.Hunters trapped,shot and poisoned more than a million coyotes in the 1900s.It’s still one of America’s most hunted animals. Yet the coyote has survived.How has the coyote shown this extraordinary ability? “I guess if you wanted to use one word,it’d be ‘plasticity’. ”says Erie Gese,an expert at Utah State University. Coyotes can live alone, in pairs, or in large packs like wolves,hunt at night or during the day , occupy a small region or an area up to 40 square miles;and live on all sorts of food,from lizards（蜥蜴）and shoes, to ants and melons.
Unbelievably people helped coyotes increase when they killed most of the wolves in the United States. The spreading of coyotes into city areas,though.is recent.They travel at night,crossing sidewalks and bridges.running along roads and ducking into culverts （钻入涵洞）and underpassces .No one knows why coyotes are moving into cities, but experts explain that cleverer, more human-tolerant（不怕人的）coyotes are teaching urban survival skills to new generations.
Occasionally. coyotes might attack human beings. There have been about 160 attacks on people in recent years Therefore, people have been consistently told not to feed coyotes or leave pet food unsecured. That ,plus a large trapping program in the neighborhood, has cut down on the coyote population.

答案：
(答案→)63---66 ADCA
解析：
63．解析：这是一道词义推断题。从丛林狼可以独居、群居，可以晚上捕食也可以白天捕食，地盘可大可小，食物种类多可以推断出丛林狼的适应环境能力非常强。
64．解析：这是一道主旨题。第一段描述丛林狼扩散到城市成为城市丛林狼，第二段描述丛林狼的环境适应能力使之可以在城市生存，第三、四段描述丛林狼进入城市的过程和市民的反应。整篇都是围绕丛林狼的扩散到城市以及生存的原因进行描述。
65．解析：这是一道细节判断题。从第三段最后一句“teaching urban survival skills to new generations”可知选C.选项A不对是因为丛林狼是到处都有而不是在西部。选项B错误是因为丛林狼早上晚上都可以出来捕食；选项D错误是虽然大量捕杀，但是丛林狼适应性强还是生存下来了。
66．解析：这是一个细节推断题。根据最后一段第3句：“people have been consistently told not to feed coyotes ”可以推断选A。
