7、危险之中。 大约 270 只大熊猫栖息于中国西北部的秦岭山脉地区，这占世界野生大熊猫总数的五分之一。据这一地区的调查研究推测，随着全球变暖本世纪竹子的产量将平稳下滑。 “除非大熊猫能够找到另外一种食物资源来代替竹子，否则它们将很可能面临食物短缺的困境。大熊猫可是个挑剔的食客。 ” 大熊猫的食物中 99%都是竹子，它们平均每天吃掉的竹子达到 38 千克。竹子本身再生率低，每 30 年至 35年为一个生长周期，这也就意味着竹子适应当地气候变化的过程很慢。 根据这个调查得出的数据，调查者预测随着气候越来越暖，三种竹子将濒临灭绝。而这三种竹子正是几乎秦岭地区的大熊猫的全部食物源。 调查研究的发起者们写
8、道：调查结果表明到 21 世纪末秦岭地区基本上所有大熊猫的栖息地将很可能消失。 滥伐森林正在在并且已经威胁着世界上将近一半种类的竹子的生存。 调查者说到自古以来竹子的分布状况都随着气候的变化而波动。不过在现代，即使其他地区从气候因素上来讲更适合竹子的生长，但是这些地区与目前大熊猫保护区相隔太远，没有重合区。 这些调查结果应该用于主动保护计划中，保护那些有更好的气候条件提供充足的食物资源的地区，或者为大熊猫搭建起快速摆脱饥荒的自然通道。 重点单词:1. breeding brid n. 繁殖，饲养2. picky pk adj. 挑剔的；吹毛求疵的3. deforestation ,di,frs

23、北京）Plastic-Eating Worms7Humans produce more than 300 million tons of plastic every year. Almost half of that winds up in landfills(垃圾填埋场), and up to 12 million tons pollute the oceans. So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of so
24、me hungry worms. Researchers in Spain and England recently found that the worms of the greater wax moth can break down polyethylene, which accounts for 40% of plastics. The team left 100 wax worms on a commercial polyethylene shopping bag for 12 hours, and the worms consumed and broke down about 92
25、milligrams, or almost 3% of it. To confirm that the worms chewing alone was not responsible for the polyethylene breakdown, the researchers made some worms into paste(糊状物) and applied it to plastic films. 14 hours later the films had lost 13% of their mass apparently broken down by enzymes (酶) from
26、the worms stomachs. Their findings were published in Current Biology in 2017. Federica Bertocchini, co-author of the study, says the worms ability to break down their everyday food beeswax also allows them to break down plastic. Wax is a complex mixture, but the basic bond in polyethylene, the carbo
27、n-carbon bond, is there as well, she explains, The wax worm evolved a method or system to break this bond. Jennifer DeBruyn, a microbiologist at the University of Tennessee, who was not involved in the study, says it is not surprising that such worms can break down polyethylene. But compared with pr
28、evious studies, she finds the speed of breaking down in this one exciting. The next step, DeBruyn says, will be to identify the cause of the breakdown. Is it an enzyme produced by the worm itself or by its gut microbes(肠道微生物)?Bertocchini agrees and hopes her teams findings might one day help employ
29、the enzyme to break down plastics in landfills. But she expects using the chemical in some kind of industrial process not simply millions of worms thrown on top of the plastic. 1. What can we learn about the worms in the study?A. They take plastics as their everyday food. 8B. They are newly evolved
30、creatures. C. They can consume plastics. D. They wind up in landfills. 2. According to Jennifer DeBruyn, the next step of the study is to . A. identify other means of the breakdownB. find out the source of the enzymeC. confirm the research findingsD. increase the breakdown speed3. It can be inferred
31、 from the last paragraph that the chemical might . A. help to raise wormsB. help make plastic bagsC. be used to clean the oceansD. be produced in factories in future4. What is the main purpose of the passage?A. To explain a study method on worms. B. To introduce the diet of a special worm. C. To pre
32、sent a way to break down plastics. D. To propose new means to keep eco-balance. B9Their cheery song brightens many a winters 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 Domino
33、ni, 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 p
34、ut 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 o
35、f 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
36、 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
37、 active at night and very noisy and people cant 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 (兴旺) in noisy environments. A st
38、udy from California Polytechnic State University found more hummingbirds in areas with heavy industrial machinery. It is thought that they are capitalising on their predators (天敌) fleeing to quieter areas.1.According to Dr Dominonis study, what causes robins to sing so much?A. The breeding season.B.
39、 The light in modern life.C. The dangerous environment.D. The noise from heavy machinery.102.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 peoples hearing
40、 might be affected.3.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.4.Why do some birds thrive in noisy environments?A. Because there are fewer dangers.B. Because there is more food to eat.C.
41、 Because there is less light pollution.D. Because there are more places to take shelter.CMore than one in 10 of the UKs wildlife species is threatened with extinction (灭绝) and the number of the nations most endangered creatures has fallen by two-thirds since 1970. The abundance of all wildlife has a
42、lso fallen, with one in six animals, birds, fish and plants having been lost, a State of Nature report found.Together with historical deforestation (毁林) and industrialization, these trends have left the UK “among the most nature-exhausted countries in the world“, with most of the country having gone
43、 past the stage at which “ecosystems may no longer reliably meet societys needs“.The comprehensive scientific report, gathered by more than 50 conservation organizations, spells out the destructive impact of modern farming and climate change on habitats from farmland and hills to rivers and the coas
44、t. “The fall in wildlife wasnt just all back in 70s and 80s, its still happening now,“ said Mark Eaton, at RSPB and the lead author of the report. “Were getting more efficient in our farming. In a way its something to be celebrated how good our farming science and technology is, but it does squeeze
45、nature out.“Eaton said there were good examples of wildlife and habitat recovery, but such projects were too few to turn the tide, with public funding for natures diversity having fallen by 32% from 112008 to 2015. “The ability to do it is within our grasp; its just about resources and the willingne
46、ss. The natural world is in serious trouble and it needs our help as never before. We continue to lose the precious wildlife that enriches our lives and is essential to the health and well-being of those who live in the UK. But the State of Nature 2016 report gives us cause for hope too. Landscapes
47、are being restored, special places defended, struggling species being saved and brought back. But we need to build significantly on this progress if were to provide a bright future for nature and for people.“Overall, the new report found that 56% of species declined between 1970 and 2013, and 53% be
48、tween 2002 and 2013. While the rest of the species were increasing, were seeing a lot of disorder, some species going up really fast and some going down equally fast. It doesnt look like a healthy, natural situation. If that carries on, you end up with just 50% left.1.How is Paragraph 1 mainly devel
49、oped?A. By listing figures. B. By giving examples.C. By analyzing causes. D. By making comparisons.2.What does the underlined part mean?A. Modern farming must return to nature.B. Modern farming makes full use of nature.C. Modern farming can enrich natures diversity.D. Modern farming may disturb natures balance.3.What does the last but one paragraph mainly suggest?A. Endangered wildlife must be well protected.B. People should unite to fight for a bright future.C. The situation
