evidence that it caused the worlds first horses to shrink nearly 50 million years ago.In fact,a team from the universities of Florida and Nebraska says it has found a link between the Earth heating up and the size of mammalshorses,in this case,the last time the world heated up.The scientists used fossils to follow the evolution of horses from their earliest appearance 56 million years ago.As temperatures went up,their size went down,and vice versa;at one point they were as small as a house cat,said Dr Jonathan Bloch,curator(馆长) of the Florida Museum of Natural History,was quoted by the DailyMail as saying.The scientists say that the current warming could have the same effect on mammalsand could even make humans smaller.“Horses started out small,about the size of a small dog like a miniature schnauzer(雪纳瑞犬).Whats surprising is that after they first appeared,they then became even smaller and then dramatically increased in size,and that exactly corresponds to the global warming event,followed by cooling.It had been known that mammals were small during that time and that it was warm,but we hadnt understood that temperature specifically was driving the evolution of body size,”Dr Bloch said in the Science journal.1How did the scientists find out the evolution of horses?A.By using fossils.B.By following the horses.C.By heating up.D.By studying cats.解析细节理解题。根据文章第三段可知,科学家用化石来追溯马从5,600万年前诞生至今的进化历程。答案A2Which of the following sentences is NOT true,according to the passage?A.Global warming has happened more than once.B.The Earth heating up was connected with the size of horses.C.Horses first appeared on the Earth 56 million years ago.D.The present global warming is sure to make humans shorter.解析细节理解题。根据文章倒数第二段可知,当前的全球变暖“可能”而不是“必定”会让人类的个子变矮。答案D3What does the underlined word“miniature”in the last paragraph probably mean?A.Small.B.Large.C.Natural.D.Gentle.解析词义猜测题。根据单词“miniature”中的前缀“mini(小的)”可知。另外,根据画线词miniature出现的句子的语境“马最初的个头很小,和一只小狗的个头差不多,大约也就像一只雪纳瑞犬那么大”可知。答案A4What would be the best title for the passage?A.Global Warming Could Make Humans ShorterB.Scientists from Florida and NebraskaC.Horses Used to Be Like CatsD.Dr Jonathan Bloch解析标题概括题。科学家们研究发现“地球温度的变化影响着哺乳动物身体的大小”,继而科学家发出警告,全球变暖可能会使人类变矮。故选项A作为标题最佳。答案AB(导学号51860005)(2017全国高考)After years of heated debate,gray wolves were reintroduced to Yellowstone National Park.Fourteen wolves were caught in Canada and transported to the park.By last year,the Yellowstone wolf population had grown to more than 170 wolves.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.By the 1920s,wolves had practically disappeared from the Yellowstone area.They went farther north into the deep forests of Canada,where there were fewer humans around.The disappearance of the wolves had many unexpected results.Deer and elk populations-major food sources(来源) for the wolf-grew rapidly.These animals consumed large amounts of vegetation(植被),which reduced plant diversity in the park.In the absence of wolves,coyote populations also grew quickly.The coyotes killed a large percentage of the parks red foxes,and completely drove away the parks beavers.As early as 1966,biologists asked the government to consider reintroducing wolves to Yellowstone Park.They hoped that wolves would be able to control the elk and coyote problems.Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.The government spent nearly 30 years coming up with a plan to reintroduce the wolves.The U.S.Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone.Today,the debate continues over how well the gray wolf is fitting in at Yellowstone.Elk,deer,and coyote populations are down,while beavers and red foxes have made a comeback.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.5What is the text mainly about?A.Wildlife research in the United States.B.Plant diversity in the Yellowstone area.C.The conflict between farmers and gray wolves.D.The reintroduction of wolves to Yellowstone Park.解析主旨大意题。通读全文,尤其是首尾两段可知,文章主要介绍黄石公园重新引进灰狼的事情。答案D6What does the underlined word “displaced” in paragraph 2 mean?A.Tested.B.Separated.C.Forced out.D.Tracked down.解析词义猜测题。从第二段第一句“GraywolvesoncewereseenhereandthereintheYellowstoneareaandmuchofthecontinentalUnitedStates,buttheyweregraduallydisplacedbyhumandevelopment.”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”。答案C7What 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.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。答案A8What is the authors attitude towards the Yellowstone wolf project?A.Doubtful.B.Positive.C.Disapproving.D.Uncaring.解析推理判断题。从文章最后一句“TheYellowstonewolfprojecthasbeenavaluableexperimenttohelpbiologistsdecidewhethertoreintroducewolvestootherpartsofthecountryaswell.”可推知,作者对于黄石公园引进灰狼群持肯定态度。答案B四、七选五阅读理解(导学号51860006)A laugh track,sometimes called canned laughter,is a collection of pre-recorded audience laughter and applause sounds added to television programs during post-production.The main purpose of the track is to trigger(激发) a response from home viewers who may not understand all of the intended humour when watching a taped sitcom(situation comedy).1Therefore,canned laughter causes natural reactions to comedies.2The producers of the HankMcCuneShow added canned laughter after the shows taping.Until that time,other radio and television comedies used a live studio audience or no canned laughter at all.In 1953,a sound engineer named Charley Douglass invented the Laff Box,a small electronic device(装置) containing numerous sounds of recorded laughter and applause.It is said that Charley Douglass selected almost all of his laugh track material from in-studio recordings of several different comedy shows.3During the 1970s,many sitcoms chose to get rid of the practice altogether or mix live audience reactions with the canned laughter.Filming a show in front of a live audience became a symbol of honour.4 Live audiences did not always provide a usable response,especially after a long day of retakes.Today,the same co
