英语四级长篇阅读段落信息匹配题练习及答案解析（11)Jaguars Don't Live Here AnymoreA)Earlier this month,the United States Fish and Wildlife Serviceannounced it would appoint"critical habitat"for the endangered jaguar.Jaguars--the world's third-largest wild cats,weighing up to 250 pounds,with distinctive black rosettes(玫瑰花色)on their fur-are a separatespecies from the smaller,tawny(黄褐色的)mountain lions,which stillroam large areas of the American West in the United States and take thefirst steps toward mandating a jaguar recovery plan.This is a policyreversal and,on the surface,it may appear to be a victory for theconservation community and for jaguars,the largest wild cats in theWestern Hemisphere.B)But as someone who has studied jaguars for nearly three decades,I can tell you it is nothing less than a slap in the face to good science.What's more,by changing the rules for animal preservation,it stands toweaken the Endangered Species Act.C)The debate on what to do about jaguars started in 1997,when,atthe urging of many biologists(including me),the Fish and WildlifeService put the jaguar on the United States endangered species list,because there had been occasional sightings of the cats crossing northover the United States-Mexico border.At the same time,however,theagency ruled that it would not be"prudent"(谨慎的)to declare that thejaguar has critical .habitat--a geographic area containing features thespecies needs to survive--in the United States.Determining anendangered species'critical habitat is a first step toward developing aplan for helping that species recover.D)The 1997 decision not to determine critical habitat for the jaguarwas the right one,because even though they cross the border from timeto time,jaguars don't occupy any territory in our country--and thatprobably means the environment here is no longer ideal for them.E)In prehistoric times,these beautiful cats inhabited significant areasof the western United States,but in the past 100 years,there have beenfew,if any,resident breeding populations here.The last time a femalejaguar with a cub()was sighted in this country was in the early1900s.F)Two well-intentioned conservation advocacy groups,the Centerfor Biological Diversity and Defenders of Wildlife,sued the Fish andWildlife Service to change its ruling.Thus in 2006,the agency reassessedthe situation and again determined that no areas in the United Statesmet the definition of critical habitat for the jaguar.Despite occasionalsightings,mostly within 40 miles of the Mexican border,there were stillno data to indicate jaguars had taken up residence inside the UnitedStates.G)After this second ruling was made,an Arizona rancher(牧场主)，with support from the state Game and Fish Department,setinfrared-camera(红外摄像机)traps togather more data,and essentiallyconfirmed the Fish and Wildlife Service's findings.The cameras didcapture transient jaguars,including one male jaguar,nick named Macho,B,who roamed the Arizona borderlands for more than a decade.ButMacho B,now dead,might have been the sole resident American jaguar,and his extensive travels indicated he was not having an easy timesurviving in this dry,rugged region.H)Despite the continued evidence,the two conservation advocacygroups continued to sue the government.Apparently,they want jaguarsto repopulate the United State seven if jaguars don't wan!to.Last March,a federal district judge in Arizona ordered the Fish and Wildlife Service torevisit its 2006 determination on critical habitat.I)The facts haven't changed:there is still no area in the United Statesessential to the conservation of the jaguar.But,having asserted thistwice already,the service,nowunder a new president,has bent to thetiresome litigation )On Jan.12,Fish and Wildlife officials,claimedto have evaluated new scientific information that had become availableafter the July 2006 ruling.They determined that it is now prudent toappoint critical habitat for the jaguar in the United States.J)This means that Fish and Wildlife must now also formulate arecovery plan for the jaguar.And since jaguars have not been able toreestablish themselves naturally over the past century,the governmentwill likely have to go to significant expense to attempt to bring themback--especially if the cats have to be reintroduced.K)So why not do everything we can,at whatever cost,to bringjaguars back into the United States?To begin with,the AmericanSouthwest is,at best,marginal habitat for the animals.More important,there are better ways to help jaguars.South of our border,from Mexicoto Argentina,thousands of jaguars live and breed in their true criticalhabitat.Governments and conservation groups (including the one I head)are already working hard to conserve jaguar populations and connectthem to one another through an initiative called the Jaguar Corridor.L).The jaguars that now and then cross into the United States mostlikely come from the northernmost population of jaguars,in Sonora,Mexico.Rather than demand jaguars return to our country,we shouldhelp Mexico and other jaguar-range countries conserve the animals'truehabitat itM )The recent move by the Fish and Wildlife Service means that therare federal funds devoted to protecting wild animals will be wasted onefforts that cannot help save jaguars.It also stands to weaken theEndangered Species Act,because if critical habitat is redefined as anyplace where a species might ever have existed,and where you or I mightwant it to exist again,then the door is open for many other sense lessefforts to bring back long-lost creatures.N)The Fish and Wildlife officials whose job is to protect the country'swild animals need to grow a stronger backbone--stick with their original,correct decision and save their money for more useful preservation work.Otherwise,when funds are needed to preserve all those small,ugly,non-charismatic endangered species at the back of the line,there maybe no money left.1.It is still a fact that there is no suitable place for jaguars to livesafely in the United States.2.The United States Fish and Wildlife Service should be moredetermined and saving for the conservation work.3.Jaguars were regarded as endangered species because of theirrare appearance at the United States-Mexico border.
