（自然與環(huán)境）導(dǎo)讀：中國(guó)瀕臨滅絕的大熊貓如今因氣候變化而陷入失去它們的主食的危險(xiǎn)之中。趕快行動(dòng)起來(lái)保護(hù)他們吧！Pandas face bamboo shortage threatAlready threatened by a slow breeding rate and rapid habitat loss, Chinas endangered giant pandas now also risk losing their main food, bamboo, to climate change, claim scientists.A study in Chinas northwestern Qinling Mountains, home to around 270 pandasabout a fifth of the worlds wild populationpredicts a big bamboo decline this century as the globe warms."The pandas may face a shortage of food unless they can find alternative food resources; the giant panda is a picky eater." Ninety-nine per cent of its diet consists of bamboobeing destroyed up to 38 kilograms per day. Bamboo itself also has a slow reproductive rate, flowering only every 30 to 35 years, which means it would be slow to adapt to a change in local climate.Based on the data gathered for this study, researchers predict that three bamboo species which make up almost the entire diet of the Qinling pandas will all but disappear in a warmer climate."Results suggest that almost the entire panda habitat in the region may disappear because of climate change by the end of the 21st century," the studys authors write.Already, deforestation is threatening the survival of about half of all bamboo species worldwide.The researchers say bamboo distribution has historically changed in response to changes in the climate. In the modern era, though, even if other areas were to bee climatically more suited for bamboo growth, these would be far away.The findings should be used for planning ahead to protect areas that have a better climatic chance of providing enough food sources or begin creating natural bridges to allow pandas an escape from bamboo famine.大熊貓面臨著食物短缺的威脅科學(xué)家們聲稱，由于一直以來(lái)受到低繁殖率和棲息地快速流失的威脅，中國(guó)瀕臨滅絕的大熊貓如今又因氣候變化而陷入失去它們的主食竹子的危險(xiǎn)之中。 大約270只大熊貓棲息于中國(guó)西北部的秦嶺山脈地區(qū)，這占世界野生大熊貓總數(shù)的五分之一。據(jù)這一地區(qū)的調(diào)查研究推測(cè)，隨著全球變暖本世紀(jì)竹子的產(chǎn)量將平穩(wěn)下滑。 “除非大熊貓能夠找到另外一種食物資源來(lái)代替竹子，否則它們將很可能面臨食物短缺的困境。大熊貓可是個(gè)挑剔的食客?！?大熊貓的食物中99%都是竹子，它們平均每天吃掉的竹子達(dá)到38千克。竹子本身再生率低，每30年至35年為一個(gè)生長(zhǎng)周期，這也就意味著竹子適應(yīng)當(dāng)?shù)貧夂蜃兓倪^(guò)程很慢。 根據(jù)這個(gè)調(diào)查得出的數(shù)據(jù)，調(diào)查者預(yù)測(cè)隨著氣候越來(lái)越暖，三種竹子將瀕臨滅絕。而這三種竹子正是幾乎秦嶺地區(qū)的大熊貓的全部食物源。 調(diào)查研究的發(fā)起者們寫(xiě)道：調(diào)查結(jié)果表明到21世紀(jì)末秦嶺地區(qū)基本上所有大熊貓的棲息地將很可能消失。 濫伐森林正在在并且已經(jīng)威脅著世界上將近一半種類(lèi)的竹子的生存。 調(diào)查者說(shuō)到自古以來(lái)竹子的分布狀況都隨著氣候的變化而波動(dòng)。不過(guò)在現(xiàn)代，即使其他地區(qū)從氣候因素上來(lái)講更適合竹子的生長(zhǎng)，但是這些地區(qū)與目前大熊貓保護(hù)區(qū)相隔太遠(yuǎn)，沒(méi)有重合區(qū)。 這些調(diào)查結(jié)果應(yīng)該用于主動(dòng)保護(hù)計(jì)劃中，保護(hù)那些有更好的氣候條件提供充足的食物資源的地區(qū)，或者為大熊貓搭建起快速擺脫饑荒的自然通道。 重點(diǎn)單詞:1. breeding brid n. 繁殖，飼養(yǎng)2. picky pk adj. 挑剔的；吹毛求疵的3. deforestation ,di,frsten n. 采伐森林；森林開(kāi)伐4. famine fmn n. 饑荒；饑餓，奇缺重點(diǎn)短語(yǔ) / 亮點(diǎn)句式：threatened by a slow breeding rate and rapid habitat loss為過(guò)去分詞短語(yǔ)作原因狀語(yǔ)。bamboo作their main food的同位語(yǔ)。如：Inspired by what he said, we are determined to study harder.在他的話的鼓舞下，我們決心更加努力學(xué)習(xí)。Tom, my uncle, will e here tomorrow.我的叔叔湯姆明天來(lái)這里。2. consists of 包含，包括。如：The course consists of ten core modules and five optional modules. 這門(mén)課程包括十個(gè)必修單元和五個(gè)選修單元。3. up to多達(dá)；該由決定；勝任；直到。如：The hotel can acmodate up to 500 guests. 這家旅館可供500位旅客住宿。Her clothes are always right up to the minute. 她的衣服總是式樣最新的。Its up to you to decide whether to go or to stay.是去是留該由你決定。He is not up to this work.他不勝任這項(xiàng)工作。4. make up 彌補(bǔ)；和解；編造；整理；化妝；拼湊成。如：I tried to make up for my loss.我力圖補(bǔ)償我的損失。 Lets make up.讓我們言歸于好吧。 The boy made up a story, it is not true.這個(gè)故事不是真的,是那個(gè)男孩編造出來(lái)的。 Leave this notice hanging on your door, asking the servant to make up your room.留張便條掛在你房門(mén)上, 請(qǐng)服務(wù)員把你的房間整理一下。 I dont like to see women making up in public.我不喜歡看見(jiàn)女人在公開(kāi)場(chǎng)合化妝打扮。 Farm workers make up only a small section of the population.農(nóng)民只占人口的一小部分。5. by the end of 到為止。如：All reports must be sent in by the end of this week. 所有的報(bào)告必須在本星期以前交齊。6. in response to 回應(yīng)。如：In response to their hospitality, we wrote a thank-you note.為回報(bào)他們的熱情，我們寫(xiě)了一封感謝信。7. far away 遙遠(yuǎn)。如：We can talk to those who live far away by telephone.我們可以用電話和住在遠(yuǎn)處的人說(shuō)話。名句背誦：A man can fail many times, but he isnt a failure until he begins to blame somebody else.

Almost half of that winds up in landfills(垃圾填埋場(chǎng)), 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 some 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 mercial polyethylene shopping bag for 12 hours, and the worms consumed and broke down about 92 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(糊狀物) and applied it to plastic films. 14 hours later the films had lost 13% of their mass apparently broken down by enzymes (酶) from 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 plex mixture, but the basic bond in polyethylene, the carbon-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 pared with previous 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(腸道微生物)?Bertocchini agrees and hopes her teams findings might one day help employ 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. B. They are newly evolved 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 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 present a way to break down plastics. D. To propose new means to keep eco-balance. BTheir 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 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 ing 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 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 (興旺) in noisy environments. A study from California Polytechnic State University found more hummingbirds in areas with heavy industrial machinery. It is thought that they are capitalising on their predators (天敵) fleeing to quieter areas.1.According to Dr Dominonis 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.2.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 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. 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 (滅絕) and the number of the nations most endangered creatures has fallen by two-thirds since 1970. The abundance of all wildlife has also fallen, with one in six animals, birds, fish and plants having been lost, a State of Nature report found.Together with historical deforestation (毀林) and industrialization, these trends have left the UK "among the most nature-exhausted countries in the world", with most of the country having gone past the stage at which "ecosystems may no longer reliably meet societys needs".The prehensive 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 coast. "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 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 2008 to 2015. "The ability to do it is within our grasp; its just about resources and the willingness. 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 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% between 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 developed?A. By listing figures.B. By giving examples.C. By analyzing causes.D. By making parisons.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 is still severe despite some progress.D. More money is needed for environmental protection.4.What is the authors purpose in writing the passage?A. To tell the British how to save wildlife species.B. To explain why more wildlife species face extinction.C. To stress the importance of protecting wildlife species.D. To introduce the current situation of Britains wildlife species.DFor centuries people have hunted animals for food and pleasure. The invention of the gun made it so easy for humans to hunt that some animals were lolled by the thousands and even became extinct(絕種的).This brings up some serious problems since breaks in the food chain upset the balance of nature.Large animals like tigers are being killed by the hundreds every year in India. The Royal Bengal tiger is the only type that exists in India and their number is greatly reduced every year because of poaching(偷獵).The present number is about 2,000,all of which live in tiger reserves. Two hundred years ago the population was 23,000 or more.During the British rule of India, many of the so-called English gentlemen killed tigers for pleasure and to show their bravery. This seems stupid because killing an innocent(無(wú)辜的)creature with a gun is not a brave deed.Today the tiger skin is very popular. Rich people and fashion designers have no idea what they are doing. petition between the rich to show off makes them blind to the serious effects. People persuade villagers to kill tigers to get money, and they do it because they are poor and need to feed their families. We must educate them, and the government should give them proper jobs to help solve this problem.The people to blame are those who buy animal products like ivories, furs, tiger bones for medicine and handbags made of animal skins. They must be put behind bars to stop this kind of trade. The earth is home for everyone on it. The trees, animals, birds, and fish of all kinds belong here as much as we do. Only we have the power to change their fate.1.What is the main idea of Paragraph 1?A. The balance of nature has long been broken by human beings.B. It is a tradition for people to hunt animals for food and fun.C. The gun is the leading cause of the extinction of many animals.D. Overhunting can lead to a series of problems in nature.2.According to the writer, the English gentlemen who played hunting games were .A. braveB. cruelC. confidentD. careless3.What does the underlined word "them" in Paragraph 4 refer to?A. Rich people.B. Fashion designers.C. Poor villagers.D. Government officials.4.What is the writers opinion on poaching?A. No buying, no lolling.B. Keep wildlife in the wild.C. Cage the cruelty, not animals.D. Shoot animals with cameras rather than guns.
