bear struggling to find food on a land without ice or snow.The poor creature can be seen dragging its bony frame(骨架) across the rough land and searching for food in a bin.Paul Nicken,the photographer who shot the heart-breaking footage,says the sight reduced him to tears.“We stood there crying—filming with tears rolling down our cheeks,” he said.They found the dying creature on Canada’s Baffin Island—an area that has seen an extreme reduction in sea ice because of global warming.Nicken says that had he stepped in,it would only have deepened the situation.Instead,he filmed the bear’s slow,painful death and posted it on social media to serve as visual proof of the impact of climate change.“When scientists say bears are going extinct,I want people to realise what it looks like.Bears are going to starve to death,” said Nicken.“This is what a starving bear looks like.”Polar bears are only native to the Arctic region and are one of the many casualties(伤亡) of climate change.They rely on the Arctic ice to hunt seals and are becoming increasingly threatened as the ice melts away.The World Wildlife Fund(WWF) predicted back in 2002 that polar bears may face extinction for losing habitat.There are an estimated 25,000 bears left in the wild and most experts agree that unless climate change is controlled,they will all be dead within the next 100 years.“The simple truth is this—if the Earth continues to warm,we will lose bears and the entire polar ecosystem.This large male bear was not old,and he certainly died within hours or days in that situation,” Nicken wrote on Instagram.But there are solutions.We must begin putting the Earth—our home—first.1.What can people see in the striking footage?A.A starving polar bear.B.Some dying creature.C.A crying photographer.D.The reduction of sea water.2.Why did Paul Nicken post the footage on social media?A.To raise people’s awareness of climate change.B.To get a prize in a photography competition.C.To attract readers’ interest in bears.D.To raise money for bear protection.3.What do we know about the polar bears from the passage?A.The polar bears that are left can be found in Canada.B.They were hunting seals when taken photos of.C.The WWF has done a lot to protect them.D.Melting ice is a huge threat to their life.4.What can we learn from the last paragraph?A.The unknown diseases increased polar bears’ deaths.B.The whole bear ecosystem will suffer a heavy loss.C.The destruction of forest affected the ecosystem.D.The polar bear will be extinct in this century.五、七选五阅读理解Cleaning up the existing damage to our environment and preventing further destruction is a huge job.It can seem that there is no way one person,especially a young person like you,can make a difference.　1　,starting with changing some simple everyday habits and working with others to spread the importance of protecting the environment.Here are a few suggestions. •Avoid unnecessary driving or being driven.Every teenager looks forward to a driver’s license and a first car,but automobiles are one of the primary causes of air pollution.If it’s too far to pedal a bike,take a bus or share your car ride with someone else.　2　,but it undoubtedly benefits the environment more. •Unplug electrical equipment when possible.Even when turned off,some appliances may still use power.　3　.So it is best to unplug anything that you do not expect to use in the next 36 hours (or more). •Carry a bag and a reusable water bottle.　4　.On the contrary,plastic bags and disposable bottles may bring convenience to you,but the environmental damage caused by them is almost permanent.Every plastic bottle not made and plastic bag not used helps a little bit. •Raise awareness.Talk to family and friends about simple changes they can make,and why they should do so to help protect the environment.　5　.It’s acceptable to just show them that you have thought a lot about the subject,are passionate about making a difference,and really can use their support. A.But you can make your contributionB.It might not seem as cool as driving yourselfC.This saves your money with fewer trips to the gas stationD.They don’t take up much space but can prevent a lot of wasteE.You don’t have to give lectures or force them to accept your opinionsF.They may be the secret sources of the large number on your electric billG.This can help start a dialogue in your community about a particular environmental issue六、完形填空One evening,Catherine was at home as usual.As her 　1　 swung between what she was going to do with her life and their dinner plans for the evening,she was unexpectedly 　2　 by an urgent call from her sister.“Get over here! Turn on NBC and check these guys out.They are just like you...” One message and a phone interview later,Catherine 　3　 herself on a bus with 8 strangers in the middle of the sweltering desert heat of Utah,picking up trash and 　4　 awareness about zero-waste and climate change. With a deep love of the environment,Catherine,Davey,and a group of self 　5　 “environmental pickup artists” went on a coast-to-coast roadside trash pickup.As they walked,sometimes only 　6　 0.9 miles in an entire day,they 　7　 and steadily made their way across the United States for three years,picking up a total of 201,678 pounds of trash. Catherine and Davey 　8　 with us wonderful stories of hope and inspiration that fuelled their 　9　 to continue their journey.After spending weeks silently worrying about how she would have enough 　10　 to fly home for their two-week spring break,Catherine found a blank,unidentified envelope 　11　 with $850 cash in the desert.Just enough to get her home and back.After their bus 　12　 outside of Denver,they unexpectedly got help and arrived in Yosemite National Park three weeks later,just in time for the “Yosemite Facelift” where 　13　 from all over the state came together with a purpose of cleaning up trash all over the park. Being at the right place at the right time became almost normal,and they realised that much of what they 　14　 was more than just a coincidence.Together,their team learned to simply 　15　 themselves to their task,and surrender to the journey. 1.A.hands　　 B.balancesC.thoughts D.positions2.A.blamed B.interruptedC.moved D.frightened3.A.dropped B.cheeredC.found D.taught4.A.abandoning B.shakingC.raising D.hiding5.A.corrected B.describedC.repeated D.discovered6.A.driving B.fixingC.riding D.covering7.A.slowly B.secretlyC.helplessly D.frequently8.A.heard B.sharedC.wrote D.read9.A.efforts B.costsC.problems D.choices10.A.time B.foodC.money D.room11.A.equipped B.suppliedC.decorated D.filled12.A.set off B.broke downC.headed for D.held on13.A.members B.volunteersC.tourists D.reporters14.A.introduced B.expectedC.experienced D.examined15.A.turn B.limitC.compare D.devote答案：一、1.plastic　2.destroyed　3.threat　4.hunt 5.extinct　6.survive　7.species　8.solar　9.endangered 10.restore二、1.conservation　2.destruction　3.incredibly 4.As　5.to finish　6.which　7.are affected　8.survival 9.have been　10.have won三、1.is to blame　2.you view the world　3.have been five times　4.We should take immediate action 5.that we live on　6.without your timely help 7.including animals and plants四、1.A　细节理解题。根据文章首句可知,《国家地理》的镜头记录了一只濒临死亡的北极熊在没有冰雪的土地上挣扎着寻找食物。2.A　细节理解题。根据第三段中的“Instead,he filmed the bear’s slow,painful death and posted it on social media to serve as visual proof of the impact of climate change.‘When scientists say bears are going extinct,I want people to realise what it looks like.Bears are going to starve to death,’ said Nicken.‘This is what a starving bear looks like.’”可知选A项。3.D　推理判断题。根据第四段中的“They rely on the Arctic ice to hunt seals and are becoming increasingly threatened as the ice melts away.”可知选D项。4.B　推理判断题。根据最后一段中的“The simple truth is this—if the Earth continues to warm,we will lose bears and the entire polar ecosystem.”可以看出,整个极地的生态系统将遭受重大损失。五、1~5 ABFDE六、1.C　根据下文中的 “swung between what she was going to do with her life and their dinner plans for the evening” 可知,Catherine的思绪(thought) 在如何处理她的生活和晚餐计划之间摇摆。2.B　根据下文中的 “by an urgent call from her sister” 可知,她的思绪被她姐姐的紧急电话打断了(interrupt)。3.C　根据下文中的 “herself on a bus with 8 strangers” 可知,Catherine发现(find)自己和8名陌生人在一辆公共汽车上。4.C　根据下文语境可知,此处指提高(raise)零浪费和气候变化的意识。5.B　根据下文中的 “environmental pickup artists” 可知,他们自称是(describe) “环保拾荒艺术家”。故选B项。6.D　根据语境可知,当他们步行时,有时一整天只走了(cover) 0.9英里路。cover此处意为 “走过,覆盖”,符合语境。7.A　根据上文中的 “0.9 miles in an entire day” 可知,当他们步行时,有时一整天只走了0.9英里路,速度缓慢(slowly)。8.B　根据下文中的 “wonderful stories of hope and inspiration” 可知,他们跟 “我们” 分享了(share) 关于希望和灵感的精彩故事。9.A　根据语境可知,Catherine和Davey跟 “我们” 分享了关于希望和灵感的精彩故事,它们激励他们努力(effort)继续他们的旅程。10.C　根据下文中的 “with $850 cash in the desert” 可知,此处指如何有足够的钱回家。11.D　根据语境可知,Catherine在沙漠中发现了一个空白的、未署名的信封,里面装着(fill) 850美元现金。12.B　根据下文中的 “they unexpectedly got help and arrived in Yosemite National Park three weeks later” 可推知,他们的公共汽车出了故障(break down)。13.B　根据下文中的 “cleaning up trash all over the park” 可知,此处指来自全国的志愿者聚集到一起。14.C　根据语境可知,他们意识到他们所经历的(experience) 事情都不仅仅是巧合。15.D　根据语境可知,他们团队学会了致力于(devote) 他们的任务。
