科普環(huán)保類 A There are an extremely large number of ants worldwide.Each individual(個體的)ant hardly weighs anything,but put together they weigh roughly the same as all of mankind.They also live nearly everywhere,except on frozen mountain tops and around the poles.For animals their size,ants have been astonishingly successful,largely due to their wonderful social behavior. In colonies(群體)that range in size from a few hundred to tens of millions,they organize their lives with a clear division of labor.Even more amazing is how they achieve this level of organization.Where we use sound and sight to communicate,ants depend primarily on pheromones(外激素),chemicals sent out by individuals and smelled or tasted by fellow members of their colony.When an ant finds food,it produces a pheromone that will lead others straight to where the food is.When an individual ant comes under attack or is dying,it sends out an alarm pheromone to warn the colony to prepare for a conflict as a defense unit. In fact,when it comes to the art of war,ants have no equal.They are completely fearless and will readily take on a creature much larger than themselves,attacking in large groups and overcoming their target.Such is their devotion to the common good of the colony that not only soldier ants but also worker ants will sacrifice their lives to help defeat an enemy. Behaving in this selfless and devoted manner,these little creatures have survived on Earth for more than 140 million years,far longer than dinosaurs.Because they think as one,they have a collective(集體的)intelligence greater than you would expect from its individual parts. 1. We can learn from the passage that ants are . A. not willing to share food B. not found around the poles C. more successful than all other animals D. too many to achieve any level of organization 2. Ants can use pheromones for . A. escape B. communication C. warning enemies D. arranging labor 3. What does the underlined expression“take on”in Paragraph 3 mean? A. Accept. B. Employ. C. Play with. D. Fight against. 4. Which of the following contributes most to the survival of ants? A. Their behavior. B. Their size. C. Their number. D. Their weight. 【答案】 BBDA【解析】[語篇解讀]　本文是一篇說明文,題材為科普知識類。介紹了螞蟻的分布、數(shù)量、大小及行為特點。 (1)細節(jié)理解題。根據(jù)文章第一段第三句話可知,除了寒冷的山頂和兩極附近,螞蟻幾乎無處不在。故選B。 (2)細節(jié)理解題。根據(jù)第二段可知,螞蟻主要依靠外激素向同伴傳遞信息。故選B。 (3)詞義猜測題。根據(jù)下文attacking in large groups and overcoming their target可知畫線短語的意思為“反抗,與……戰(zhàn)斗”。故選D。 (4)推理判斷題。根據(jù)最后一段第一句話可知,由于無私和忠誠的行為特點,這些小生物已在地球上存在了1.4億多年。故選A。 B We may think were a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices(裝置) well after they go out of style. That’s bad news for the environment — and our wallets — as these outdated devices consume much more energy than the newer ones that do the same things. To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life — from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation. Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in xx. As we accumulated more devices, however, we didnt throw out our old ones. "The living-room television is replaced and gets planted in the kids room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in xx. Were not just keeping these old devices — we continue to use them. According to the analysis of Babbitts team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions（排放）more than doubling during the 1992 to xx window. So whats the solution（解決方案）? The teams data only went up to xx, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%. 5. What does the author think of new devices? A. They are environment-friendly. B. They are no better than the old. C. They cost more to use at home. D. They go out of style quickly. 6. Why did Babbitts team conduct the research? A. To reduce the cost of minerals. B. To test the life cycle of a product. C. To update consumers on new technology. D. To find out electricity consumption of the devices. 7. Which of the following uses the least energy? A. The box-set TV. B. The tablet. C. The LCD TV. D. The desktop computer. 8. What does the text suggest people do about old electronic devices? A. Stop using them. B. Take them apart. C. Upgrade them. D. Recycle them. 【答案】 ADBA【解析】【文章大意】本文主要介紹一些過時的設備比新的設備消耗更多的能量，作者認為繼續(xù)使用舊電子產(chǎn)品既不環(huán)保也不經(jīng)濟，作者支持用新產(chǎn)品替代舊產(chǎn)品。 根據(jù)Thats bad news for the environment—and our wallets—as these outdated devices consume much more energy than the newer ones that do the same things.可知，因為這些過時的設備比新的設備消耗更多的能量，說明新電子產(chǎn)品相對環(huán)保。故選A。 根據(jù)To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life可知，實驗的目的是測量這些設備的耗電量。故選D。 根據(jù)最后They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.可知，tablets比TVs and desktop computers耗電量低，tablets最省電。故選B。 根據(jù)Thats bad news for the environment—and our wallets—as these outdated devices consume much more energy than the newer ones that do the same things.和They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.可知，作者認為繼續(xù)使用舊電子產(chǎn)品既不環(huán)保也不經(jīng)濟，作者支持用新產(chǎn)品替代舊產(chǎn)品。故選A。 C D Their cheery song brightens many a winter’s day.But robins are in danger of wearing themselves out by singing too much.Robins are singing all night―as well as during the day,British-based researchers say. David Dominoni,of Glasgow University,said that light from street lamps,takeaway signs and homes is affecting the birds’ biological clocks,leading to them being wide awake when they should be asleep. Dr Dominoni,who is putting cameras inside nesting boxes to track sleeping patterns,said lack of sleep could put the birds’ health at risk.His study shows that when robins are exposed to light at night in the lab,it leads to some genes being active at the wrong time of day.And the more birds are exposed to light,the more active they are at night. He told people at a conference,“There have been a couple of studies suggesting they are increasing their song output at night and during the day they are still singing.Singing is a costly behaviour and it takes energy.So by increasing their song output,there might be some costs of energy.” And it is not just robins that are being kept awake by artificial light.Blackbirds and seagulls are also being more nocturnal.Dr Dominoni said,“In Glasgow where I live,gulls are a serious problem.I have people coming to me saying‘You are the bird expert.Can you help us kill these gulls?’.During the breeding(繁殖)season,between April and June,they are very active at night and very noisy and people can’t sleep.” Although Dr Dominoni has only studied light pollution,other research concluded that robins living in noisy cities have started to sing at night to make themselves heard over loud noise. However,some birds thrive(興旺)in noisy environments.A study from California Polytechnic University found more hummingbirds in areas with heavy industrial machinery.It is thought that they are capitalising on their predators(天敵)fleeing to quieter areas. 9. According to Dr Dominoni’s study,what causes robins to sing so much? A. The breeding season. B. The light in modern life. C. The dangerous environment. D. The noise from heavy machinery. 10. What is the researchers’ concern over the increase of birds’ song output? A. The environment might be polluted. B. The birds’ health might be damaged. C. The industry cost might be increased. D. The people’s hearing might be affected. 11. What does the underlined word“nocturnal”in Paragraph 5 mean? A. Active at night. B. Inactive at night. C. Active during the day. D. Inactive during the day. 12. Why do some birds thrive in noisy environments? A. Because there are fewer dangers. B. Because there is more food to eat. C. Because there is less light pollution. D. Because there are more places to take shelter. 【答案】 BBAA【解析】[語篇解讀]　本文為說明文,題材為環(huán)境保護類。文章主要通過描述知更鳥在人類社會的光污染下晝夜歌唱,造成體力的嚴重消耗和睡眠缺乏,這對其壽命構成威脅,也影響到人類的睡眠環(huán)境。我們呼吁社會:給鳥類一個天堂,還人類一份寧靜。 ?(1).由文章第二段中“l(fā)ight from street lamps,takeaway signs and homes is affecting the birds’ biological clocks,leading to them being wide awake when they should be asleep”和第三段最后一句And the more birds are exposed to light,the more active they are at night.可知答案。 ?(2).由文章第三段第一句Dr Dominoni,who is putting cameras inside nesting boxes to track sleeping patterns,said lack of sleep could put the birds’ health at risk.可知答案。 (3).由上文可知,知更鳥受到人造燈光的干擾而無法入睡。根據(jù)notjust和also的提示,再根據(jù)信息句“Duringthebreedingseason,betweenAprilandJune,theyareveryactiveatnightandverynoisyandpeoplecan’tsleep.”可知,畫線詞表示“夜間活動的”。故A項正確。 (4).由文章最后一段最后一句“It is thought that they are capitalising on their predators fleeing to quieter areas.”可知,一些鳥類在嘈雜的環(huán)境下興旺是因為面臨的危險少了。故A項正確。 D Fire Prevention Information The University of Adelaide employs a full﹣time staff of fire prevention professionals． They inspect all campus buildings and test and maintain all sprinkler（噴水滅火裝置） systems，fire alarms，and fire extinguishers（滅火器）． They also provide educational programs on fire safety in the residence halls． Whenever you move to a new area， you should locate the fire alarm pull stations and the two exits nearest your room． Fire Alarms The floors of all campus buildings are equipped with manual（手動的）fire alarm systems which include fire alarm pull stations and pipes． Most are also equipped with automatic fire alarm systems consisting of heat detectors， smoke detectors and sprinklers． For your safety，never tamper with（胡亂擺弄） these systems． False fire alarms are illegal and may lead to imprisonment． Fire Drills A fire drill will be conducted in your residence hall every semester． During a fire drill，please do the following： ?Take your room key and ID，close and lock the door to your room． ?Exit immediately from the nearest emergency exit；do not use a lift． ?Meet outside of your residence hall and wait for further instructions． Fire Extinguishers Fire extinguishers are located on each floor and in each apartment． Use a fire extinguisher only if you have been trained to do so． Irresponsible use of a fire extinguisher can create a dangerous situation for other residents and could result in damage to personal property． Misuse of a fire extinguisher will result in fines． Smoke Detectors A smoke detector is on the ceiling in your room． Some buildings also have heat detectors on the ceilings． Do the following to ensure the safe operation of your smoke detector： ?If your smoke detector is working properly， the red light should be on． If the red light is not blinking（閃動）， contact residence hall staff immediately． ?Do not cover or block your smoke detector in any way． ?If a smoke detector sets off an alarm and there is no fire or smoke， inform your hall staff． 13.

Do you love it because of the trees, fascinating wildlife, or beauty that each season brings? If you woke up the next day and it was all gone, how would you feel? Sure it wouldn’t happen this fast, but there’s a definite（一定的） possibility of that happening in the future. And one step in changing the future is to recycle. Not only does recycling save the Earth, but it saves your money too. It’s like killing two birds with one stone! By recycling you throw away fewer things, which means you empty the trash less often and save money on trash bags. And for some materials you can even get paid to recycle. As well as saving money by recycling, you will save the Earth too. Recycling is one of the best and easiest ways to save our planet; by recycling there will be less waste that is buried in landfills. This may not seem very helpful but it can take over five hundred years for a landfill to completely break down! And another benefit of recycling is that there wouldn’t be as many raw materials that would be destroyed. This would save materials such as trees, oil, and water.Itwould also conserve energy and natural resources, and reduce air and water pollution, andgreenhouse gases. Your recycling may even inspire others around you to start recycling too! Imagine that you are looking for a house and you go to two different communities. One is littered with trash on the streets, while the other neighborhood is lined with recycling bins. Obviously, the cleaner neighborhood is the one you will pick. If your community is like this it could leave a lasting impression in someone’s mind. 18. What is the main idea of the passage? A. We can decide the future of the Earth. B. We are destroying the Earth gradually. C. We can do recycling as soon as possible. D. We are running out of the Earth’s resources. 19. If you do some recycling at home it means________. A. it takes great trouble for you to do so B. you should waste much of your time C. it is the only way to protect the Earth D. you can get a little income in a way 20. It can be inferred from the last paragraph that________. A. many communities are littered with trash B. recycling can contribute to a neat environment C. most people pay rare attention to recycling D. it is hard to know what others are thinking about 【答案】 ADB【解析】【文章大意】本文講述了回收利用是改變未來的措施，闡述了循環(huán)利用的好處。 由第一段Do you love the planet you live on?

A duologue, he suggested, is more than a monologue but less than a dialogue. Multiply a duologue by a roomful of people, he jokingly added, and you have a conference. Two psychologists have now given his ideas some substance, by showing that people do indeed often fail to notice when the conversations they are engaged in have been temporarily reduced to nonsense. Bruno Galantucci of Yeshiva University in New York and Gareth Roberts of Haskins Laboratories in New Haven, Connecticut, are interested in how and why languages evolve. The mainstream view of why people communicate is that they are trying to transmit information faithfully. The “information” may not be true, of course. But even lies, this view holds, are told with the hope they will be understood. Sometimes faithful transmission is indeed the intention, as when a pilot communicates, according to strict rules, with a control tower. According to Dr Galantucci and Dr Roberts, however, transmitting information efficiently takes a lot of effort and is the exception rather than the rule. In normal conversation, they report in a paper in PLOS ONE, people are surprisingly deaf to incoherence. They demonstrated this by asking pairs of student volunteers to chat using an instant-messaging program. These volunteers, who had never met, did so sitting in separate rooms. They were given the task of identifying the differences in colour between two versions of a cartoon (each could see only one version). Unbeknown to them, though, another pair were performing the same task at the same time, with a different cartoon. While the two conversations were going on, the researchers switched between them so that a student would suddenly and without warning find himself chatting to someone from the other pair. There were fou
