B.Separated.C.Forced out.D.Tracked down.答案C解析词义猜测题。从第二段第一句“Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States,but they were gradually displaced by human development.”可知,过去灰狼在黄石公园随处可见,但由于人类的发展,灰狼就逐渐被迫撤出了这个地方。可推测displace意为“被迫离开”。3What did the disappearance of gray wolves bring about?A.Damage to local ecology.B.A decline in the parks income.C.Preservation of vegetation.D.An increase in the variety of animals.答案A解析细节理解题。从第三段可知,灰狼的消失带来了许多意想不到的结果:鹿群数量迅速增多,消耗大量植被;草原狼增多,吃掉了公园里占很大比例的红狐狸;完全赶走了公园里的河狸。也就是说灰狼的消失破坏了当地的生态平衡。4What is the authors attitude towards the Yellowstone wolf project?A.Doubtful.B.Positive.C.Disapproving.D.Uncaring.答案B解析推理判断题。从文章最后一句“The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.”可推知,作者对于黄石公园引进灰狼群持肯定态度。B(导学号57140029)“Millions of animals die each year on the US roads,” the Federal Highway Administration reports.In fact,only about 80 ocelots,an endangered wild cat,exist in the US today.The main reason?Roadkill.“Eco-passages” may help animals cross the road without being hit by cars.They are paths both over and under roads.“These eco-passages can be extremely useful,so that wildlife can avoid road accidents,” said Jodi Hilty of the Wildlife Protection Society.But do animals actually use the eco-passages?Th
