Unit 4 Global warmingⅠ.阅读理解A(2017·山东济南高三高考模拟考试)Thrift stores are a refuge (避难所) for countless items from landing in garbage piles. Value Village, for example, saves more than 650 million pounds of clothing from landfills (垃圾填埋场) each year, making it one of the largest recyclers of used garments in the world. Their stores give a second life to 1.8 million pounds of clothes every day, which is equal to 600 mid­sized cars. Almost 100 percent of clothing and textiles are recyclable, yet 85 percent of them end up in landfills. It's estimated that the average person throws away 70 pounds of clothing a year.Lindsay Coulter is the so­called “Queen of Green” with the David Suzuki Foundation, educating people on how to live a greener life by making changes around the house. She says that donating or shopping at thrift stores is an excellent way to exercise all three of the three R's：reduce, reuse and recycle. She says, “Whether it's a purse or a pair of shoes, it's really worth considering going to thrift stores as another point of contact to help reduce your consumption.”Coulter points out that since landfills are airtight, textiles take longer to break down. “I'd imagine things like an old towel, a rag or an old T­shirt will last a really long time，”she says. T he beauty of thrift shopping is that the supply is neverending, so if you don't find what you're looking for one day, it's likely to show up in no time.One person who knows this quite well is Jodi Jacyk, costume specialist in the Department of Theatre and Film at the University of British Columbia. She says the majority of items for the university's productions are purchased second­hand. Because of her shrinking budget, items like clothing and shoes are thrifted from Value Village. “We are constantly thri fting and we reuse costumes for many years. Thrift shopping is a much easier, cheaper way to do things，”she says.The next time you need to lighten your closet, take the opportunity to go thrift shopping to lighten both your carbon footprint and your financial burden at the same time.【解题导语】本文主要介绍了一种环保的生活方式，即去慈善商店捐或购买二手衣物。

Unit 4 Global warming 专题练习I.阅读理解AA few weeks ago a group of scientists produced a report about global warming and the natural world. They wanted to find out if global warming was dangerous for plants and animals. The scientists were surprised by what they found. They saw that during the next 50 years about 25% of land animals and plants will disappear from the earth. More than 1 million plant and animal species will die out by 2050.The head of the research team, Christ Thomas, who is a professor of conservation biology at Leeds University, said the results of their research were frightening. More than 10% of all plants and animals will disappear from the earth. It is too late to save many plants and animals because of the greenhouse gases that are already in the atmosphere. But the scientists say if we control greenhouse gases now, we can save many more plants and animals from disappearing.The scientists studied some areas of the world with very rich biology. These areas were Europe, Australia, Central and South America, and South Africa. Their studies showed that species living in mountainous areas had a better chance of survival because they could move uphill to get cooler. In flat areas, such as deserts, plants and animals would have to move very long distances to get cooler, so they are in great danger of dying out. The scientists found many surprising things. For example, they found that half of the 24 species of butterfly they studied in Australia would soon disappear.1.According to this passage, global warming can be best described as ________ to many plants and animals.A.deadlyB.surprisingC.disappointingD.frightening2.What's the purpose of the research led by Christ Thomas?A.To protect animals and plants from global warming.B.To call on people to control greenhouse gases.C.To warn us of the dying out of many animals and plants.D.To study the effect of global warming on animals and plants.3.What can be the best title of this passage?A.Greenhouse effect and global warmingB.Extinct animals in the worldC.A frightening discovery concerning global warmingD.Disappearance of butterflies4.We can learn from the passage that ________.A.about 25% of land animals and plants have disappeared from the earthB.in about four decades more than 1 million plants and animal species will die outC.we can do nothing to save the plants and animalsD.wildlife in flat areas can't find enough foodBHalf of the world's coral reefs have died in the last 30 years. Now scientists are racing to ensure that the rest survive.The planet's health depends on the survival of coral reefs. They are often described as underwater rainforests. In addition, the reefs serve as barriers that protect coastlines from the full force of powerful storms. Corals are used in medical research on treatment for diseases. They are key to local economies, as well, since the reefs attract tourists, the fishing industry, and other businesses, bringing in billions of dollars of revenue (收入).Corals are invertebrates, or animals that lack a backbone. They live mostly in tropical waters. The corals release a substance called calcium carbonate, which forms protective skeletons around them. The skeletons grow and take on vivid colors. This is the result of the corals' symbiotic (共生的), or mutually beneficial, relationship, with algae (藻类) that live in their tissues and give them energy.But corals are particularly sensitive to changes in temperature. A rise of just 1 to 2℃ can force the corals to drive out the algae. Then the corals' skeletons turn white in a process called “bleaching (白化).” Corals can survive in these higher temperatures only for a few months.The problem for the reefs increased greatly during a recent extended El Niño weather phenomenon. In 2015-2016, the longer El Niño warmed the Pacific near the equator, which led to the most widespread bleaching of coral reefs ever recorded. This bleaching event continues to create problems for the world's reefs.In the Indian Ocean, near the islands of the Maldives, about 73% of the coral reefs suffered bleaching between March and May 2016. Areas in the central Pacific were hit the hardest — about 90% of the reefs were destroyed in the waters of the Republic of Kiribati.And the problem is not just global warming. The reefs have also been affected by pollution, coastal development, and overfishing.Scientists remain hopeful that it's not too late to save the reefs, and some are moving ahead on experiments to accomplish that goal. Ruth Gates, director of the Hawaii Institute of Marine Biology, said, “It's high time that we should start thinking outside the box. It's sort of a no-win game if we do nothing.”5.What's the focus of Paragraph 2?A.The vital role of coral reefs.B.The seriousness of pollution.C.The importance of ocean species.D.The difficulties of protecting reefs.6.What is the character of corals?A.They are fish-friendly.B.They are tropical species.C.They depend on algae to survive.D.They can reflect different colors.7.What is the result of the recent El Niño?A.Coral reefs are extinct in Kiribati.B.The Indian Ocean suffered the most.C.Most of the world's reefs fell victim to it.D.It caused record-breaking coral bleaching.8.What do Ruth Gates' words imply?A.Reefs need to be saved urgently.B.Saving reefs is a win-win game.C.It is a challenging job to save reefs.D.Reef-saving efforts have turned out to be fruitless.II.七选五PollutionPollution happens when the environment is dirtied, by waste, chemicals, and other harmful substances (物质). Pollution is a problem all over the world. But it is especially bad in large cities with a lot of industries and cars. __9__ Wildfires, volcanoes, and industrial chemicals cause some air pollution. But most air pollution comes from burning fossil fuels (矿物燃料). These include coal, oil, and natural gas. The burning of fossil fuels may release harmful gases. Air pollution may cause such diseases as cancer and asthma. It also leads to polluted rain that can harm living things. __10__ Finally, air pollution damages the ozone layer (臭氧层), which is important because it protects Earth against harmful rays from the sun.Causes of water pollution are easy to see. People dump (倾倒) garbage and dirty water into rivers, lakes and oceans. Factories or cities sometimes release poisonous chemicals, and other wastes into water. These chemicals may make the groundwater unfit to drink. __11__Littering, or throwing garbage on the ground, is a form of land pollution. Litter can destroy the habitats of plants and animals. The buildup of dangerous chemicals in the ground is another form of land pollution. The chemicals may come from farms or factories. __12__ They may even harm people who eat the polluted plants and animals.Many governments, environmental groups, and ordinary people are working to control pollution. Governments have passed laws to keep people from releasing dangerous chemicals into the environment. __13__ Instead they are getting power from the sun, wind, water, and other energy sources that produce less pollution. Many communities use recycling to reduce pollution.A.Farmers use chemicals to help crops grow.B.This type of pollution may be seen in big cities.C.They also can harm fish and other forms of life.D.These chemicals can spread to plants and animals.E.In addition, air pollution may be a cause of global warming.F.There are three main forms of pollution: air, water, and land.G.Some companies and people are trying to use fewer fossil fuels.III.语法填空The term “eco-friendly” is used to describe activities which are good for the environment. There are different ways in 14 activities can be eco or environmentally friendly, from producing products in an environmentally friendly way to 15 (make) lifestyle changes that are designed to benefit the environment.People take part in eco-friendly activities because they are 16 (concern) about the health of the environment. Environmental problems first 17 (cause) public consciousness (意识) in the late 1900s, when people realized that their activities were having 18 bad effect on the environment. Pollution, overuse of 19 (nature) resources (资源), and other activities 20 (consider) to be hurting the environment, so people began to look into more environmentally friendly ways 21 (live) as well as doing business.It was the belief that investing in green product development would pay off that made many companies make changes. 22 a result, eco-friendly products can be found in many regions of the world today. These products are 23 (usual) made in factories which are environmentally friendly, such as equipment built from recycled materials which are also good for the environment.参考答案I.阅读理解A动植物来说是致命的。

Unit 4 Global warmingⅠ.阅读When we think of how cities will look in the future,we probably picture tall gray buildings and skies filled with flying cars.One city in Australia,however,is trying to change that image.Earlier this month,it was reported that the city of Melbourne plans to build a pair of tall towers,which look more like massive (巨大的) tree houses than skyscrapers (摩天大楼).The project,known as the Green Spine,will turn Melbourne’s skyline from gray to green once the two towers are completed,with one of the buildings becoming the tallest in the Southern Hemisphere,at 356.2 meters tall.Both towers will have balconies running down one side,filled with plants and trees.Meanwhile,on the top of each tower,a botanical garden will offer a relaxing space where visitors can enjoy nature,away from the noise of the city.“Our green spaces are our city’s lungs,its shade from the sun,〞building architect Phil Rowe said in a news release.In spite of their proposed (计划的) size,these buildings are just a small part of a wider trend for greener and more eco-friendly structures.Plans are already underway in several cities around the world to build entire skyscrapers from wood,with an 18-story building made from pine already existing in Minneapolis,US.Indeed,in this modern age of technology and tall buildings,it seems that people just want a touch of nature in their lives.“The 20th century was the concrete (混凝土的) age;it was all about the dominion(统治) of man over nature,〞British architect Anthony Thistleton told theBBC.“Now,we’re transitioning (转变) toward a different attitude,a more nurturing (滋养的) one.〞The move toward making cities greener places isn’t a new concept.One just needs to look at places such as New York’s Central Park to see that natural spaces and sprawling (伸展的) cities have been partners for hundreds of years.And,of course,wooden buildings themselves have been around far longer than concrete and steel ones.In fact,China’s wooden Fogong Temple Pagoda,located in Shanxi province,is still standing almost 1,000 years after it was built.So,like many other trends from fashion to technology,it seems that humankind is taking a step backwards to a simpler time.Our future may not be as we pictured it,but it’ll certainly be a lot greener.1.According to the text,Melbourne’s Green Spine will be .A.the highest buildings in the worldB.made entirely from woodC.skyscrapers to solve pollution problemsD.filled with green plants and trees2.Why did the author mention New York’s Central Park and China’s wooden Fogong Temple Pagoda?A.To compare their design concepts.B.To show the idea of green cities has a long history.C.To point out where the Green Spine drew inspiration from.D.To stress concrete and steel buildings will be out of date soon.3.What will the trend of future buildings probably be,according to the author?A.They will be taller and brighter.B.They will be filled with high-tech concepts.C.They will be more eco-friendly.D.They will no longer use concrete and steel. 语篇解读:本文主要介绍了墨尔本市将要建造两座巨塔,而这两座巨塔的设计融入了绿色、环保的理念。

Everyone knows that death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two stages — clinical or temporary death and biological death. Clinical death occurs when the vital organs, such as the heart or lungs, have stopped functioning, but have not suffered permanent damage. The organism can still be saved. Biological death occurs when changes in the organism lead to the “breaking up” o f vital cells and tissues. Death is then unchangeable and final.Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs. The best method developed so far involves cooling the organism, combined with narcotic (麻醉) sleep. By slowing down the body’s metabolism (新陈代谢), cooling delays the processes leading to biological death.To show how this works, scientists performed an experiment on a six-year-old female monkey called Keta. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began taking blood out from an artery (动脉). The monkey’s blood press ure decreased and an hour later both the heart and breathing stopped: clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing. After two minutes Keta’s heart became active once more. After fifteen minutes, spontaneous (自发的) breathing began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin (青霉素) injection, Keta seized the syringe (注射器)and ran with it around the room. Her behavior differed little from that of a healthy animal.1.For a person who suffers from the clinical death _________.A. he is still very much aliveB. he cannot avoid final deathC. his most important organs are damaged foreverD. he still has the possibility of getting back to life2.Scientists try to make the time of clinical death longer in order to _________.A. cool the organismB. delay the coming of biological deathC. slow down the body’s metabolismD. bring vital cells and tissues back to active life3.The text mainly talks about _________.A. clinical death and biological deathB.an experiment on a monkeyC. the meaning of deathD. the process before death4.From the underlined sentence in the last paragraph we can know that _________.A. Keta was impoliteB. Keta was healthyC. Keta was illD. Keta was crazy【文章大意】本文要紧叙述了为了延缓生理死亡的到来，科学家尽量延长临床死亡的时刻。

2019届高三英语一轮复习Unit4Globalwarming练习新人教版选修Ⅰ.阅读理解AWant to help fight global warming? Take off your tie, says the Italian health ministry.It ha s urged employers to let their staff dress casually at work in the summer so that the air conditioning can be turned down.“Taking your tie off immediately lowers the bodytemperature by 2 or 3 degrees centigrade，” the ministry said in a statement. “Allowing a more sensible use of air conditioningbrings about electricity savings and protects the environment.”It called on all public and private offices to let employees wear no tie during heat waves like the one that has brought Africa­like temperatures to many parts of Italy this week.The move echoes (回应) a similar action from Italy's biggest oil group, ENI, which told its staff earlier this month they need not wear a tie at work.The tie makers, however, were left hot_under_the_collar.“Italy confirms that it is a strange country，” Flavio Cima said angrily in a letter to financial daily Il Sole 24 ORE under the headline: “I, tie maker, am responsible for global warming.”“We can now happily continue with our lifestyle, using cars, consuming fuel, heating and cooling our homes at leisure. On one condition: we should not wear a tie while we do so，” he wrote.“I should have listened to my friends and become an oil producer instead.”Italy is one of the European Union's worst performers on the pollution front and is among the EU countries expected to exceed (超出) their greenhouse gas emission (排放) targets.语篇解读：本文是一篇夹叙夹议文。

This time last year I entered two long­distance mass­participation swimming events，including the Jubilee River 10 km swim.At the last minute，just before both swims，I decided to pull out.The reality is，I live in fear of coming last.Last year，before the two events，I realized that I couldn't deal with coming last.I had looked at the swim times of those who had completed the previous year and calculated that，at my current swim pace，I would probably have come last in both.I just couldn't face it.But when next year came around，I decided to enter those same events again.For a few months，I trained hard，but I didn't get any faster.Then it was June 5，the day of the Jubilee River 10 km.The event started at 9：30 a．m.，and the swimmers were anxious and eager to start.As I swam along，the river was quiet and clean and everything was peaceful.The sun shone.Meadows(草地)rolled by and every now and then someone would wave at the scene unfolding in the water.As the day wore on，somehow I didn't mind that，predictably，almost everyone was ahead.There were at least some swimmers still near me，and although we shared the same river we quietly occupied our own spaces.As I concentrated on doing my own thing，watching the sky，the bank，the other swimming caps passing or not passing，I realized I was enjoying myself.In the end，four hours and 29 minutes after I'd started，I staggered(摇摇晃晃地走)out of the water and was greeted with a smile and a“well done”from the race organizer.I glanced back over my shoulder toward the water and noticed that there were a small handful of swimmers who were still to finish，behind me，out of a field of around 300 swimmers.But it didn't matter.I_was_just_relieved，proud_and_happy_to_finish.As I drove away，my thoughts turned to my next long race of the season and how much I was looking forward to it，my fears of coming last gently receding(渐渐远去)．1．The author intended to quit swimming mainly because ________.A．she feared that she couldn't finish the two racesB．she was afraid that she would let family members downC．she was unwilling to accept the possibility of finishing lastD．she wasn't fully prepared for the two races2．The author hopes to convey the message that ________.A．never give up when facing challengesB．it is process that matters mostC．failure is the mother of successD．winners always take it all3．What does the underlined sentence mean in Paragraph 5?A．She took pride in leaving all the other swimmers behind.B．She was proud that she was not the last one in the race.C．She was glad to finish the race and had a sense of relief.D．She was proud to be praised by the organizer.4．It can be inferred from the end that the author is likely to ________.A．participate in another race without any hesitationB．analyze the reason why she failed in the raceC lose confidence completelyD．decide whether she is suitable for the race【解题导语】作者通过描述自己参加游泳比赛的经历告诉我们最后一名并不可怕，关键是要学会享受比赛的过程。

1(compare) to other natural changes, the temperature of the earth is rising rapidly. So2has this come about and does it matter? All scientists subscribe to the view3the increase in the earth's temperature is due to the burning of fossil fuels4(produce) energy. Some byproducts of this process are called “greenhouse” gases, the most important one of5is carbon dioxide. When huge quantities of extra carbon dioxide6(add) into the atmosphere, more heat energy tends7(trap) in the atmosphere causing the global temperature to goup. The attitudes of scientists towards this rise are8(complete) different. Some think that the trend in which the temperature increases by 5 degrees would lead to a catastrophe.

Good failures happen when, even though you made the correct decision, you still lost. Bad failures happen because you mad e bad decisions, or worse, didn’t make a decision at all. Although the two feel the same, they have a completely different long-term impact.By separating the two types of failures, it is easier to persevere through good failures. It may hurt to have your business proposal shut down for the fifteenth time, but it isn’t necessarily a bad failure. You can also avoid more bad failures. If you fail because of laziness, indecision or poor planning, you can quickly correct those in the future.I’ve foun d that there are several categories of good failures. Since they come from good, not bad, decisions, they are the best way to fail.1. High Upside, Low DownsideThere are many areas of life where the upside is far greater than the downside. When I write an article, it takes about 90 minutes of work. If nobody responds to that post, then I’ve just wasted 90 minutes. However, if the article becomes popular, it can bring in thousands of visitors to my website. Those thousands of visitors translate into new readers who can get value from the website. In addition, it often results in a higher monthly income for me.2. Breaking through Your LimitsThe only way to know your limits are to go past them. Occasionally I’ve committed myself to more work than I can handle. The result is stress. However, if not, youcan never improve. You’ll always go slightly below your capacity, never reaching your possible potential. Occasionally facing an exhausting schedule ensures my productivity muscles stay strong.3. Taking on Too Big a ChallengeI’ve of ten se t goals that were nearly impossible to accomplish. I didn’t have enough time to reach the deadline and I had no idea what I was doing. Although setting extremely difficult challenges results in a lot of failures, it keeps you sharp.Why failure can be good?【参考答案】任务型读写76.Definitions/ Meanings/Concepts 77.correctly 78.impact/influence/affect 79.

Unit 4 Global warming课时作业Ⅰ.阅读理解A(2019·山师附中模拟)Sometimes we may find that every week there are a lot of new stories about how climate change is affecting the planet，or new plans to battle its effects.But the concept itself isn't new at all—in fact，scientists have been exploring questions about climate change for almost 200 years.The idea of “greenhouse gases〞 goes back to 1824，when Joseph Fourier wondered what was regulating the earth's temperature.Fourier concluded that the atmosphere must be responsible for containing the heat absorbed from the sun and described it as a box with a glass lid.As light shines through the glass，the inside gets warmer as the lid traps the heat.As Fourier's ideas spread，it came to be called “the greenhouse effect〞．Scientists continued to study the greenhouse effect.Not until a Swedish chemist named Svante Arrhenius came along，did scientists understand how global warming actually works.After years of work，Arrhenius determined that the level of carbon dioxide in the atmosphere did in fact have a direct effect on global temperatures.Arrhenius found that CO2，and other gases trap radiation，which warms the atmosphere.Arrhenius was the first to suspect that burning coal could contribute to the greenhouse effect.But Arrhenius welcomed the warming effect on the planet.At a lecture later that year，Arrhenius noted that creatures of a warmer earth “might live under a milder sky and in less barren surroundings〞．While Arrhenius' findings won him the 1903 Nobel Prize in chemistry，scientists kept debating whether the greenhouse effect was increasing until 1950，when researchers finally began to find strong data supporting it.By the end of the 1950s，American scientists had been sounding the alarm on the long－term consequences ofclimate change.Climate change research has come a long way since Fourier first described the greenhouse effect－still，maybe Arrhenius should have been more careful of what he wished for.【文章大意】本文主要讲述了科学家们对气候变化的众多探索。

Global warming李仕才一、阅读理解Recently I and other Red Cross volunteers met a group of victims from Hurricane Katrina. We were there, as mental health professionals, to offer ＂psychological first aid＂and I was struck by the simple healing power of presence. As we walked in the gate to the shelter, we were greeted with a burst of gratitude (感激) from the first person we met. I felt appreciated, but also guilty, because I hadn’t really done anything yet.I first realized the power of presence many years ago when a friend’s mother passed away unexpectedly. I had received a call saying she had just passed away. I wanted to rush down there immediately, but didn’t want to intrude (打扰) on this very personal period of sadness. I was torn about what to do. Another friend with me then said, ＂Just go. Just be there.＂I did, and I will never regret it.Since then, I have not hesitated to be in the presence of others. Once I sat at the bedside of a young man suffering from the pain of his AIDS —related dying. He was not awake, and obviously unaware of others’presence. However, the atmosphere was by no means solemn. His family, playing guitars and singing, allowed him to be present with them as though he were still fully alive.In my life, I am repeatedly struck by the healing power of presence. In it, none of us are truly alone. It is not only something we give to others but also changes me for the better.1.Why were the hurricane victims grateful to the author?A. He built shelters for them.B. He gave immediate first aid to them.C. He came to stay with them.D. He brought mental health professionals.2.What did the author do when his friend’s mother passed away?A. He hesitated over whether to go.B. He went to his friends’at once.C. He knew what to do instantly.D. He decided not to disturb.3.What does the underlined word ＂solemn＂in Paragraph 3 probably mean?A. Heavy but warm.B. A little sad but cosy.C. Relaxing and delightful.D. Very serious and unhappy.4.What has the author learned from his experience?A. A friend in need is a friend indeed.B. Being present can make a big difference.C. The family harmony is the happiest thing in life.D. Being a volunteer can make one’s life more significant.【文章大意】本文是一篇记叙文。

Unit 4 Global warming阅读理解·组块专练——练速度(限时：35分钟)Ⅰ.阅读理解A(2016·济南市高三调研) For twenty years, I saved all my college course notes and textbooks: that's a lot of paper.Worse, it's not easy to carry them around — and trust me, they aren't light —on at least seven moves. Yet I never once looked at them. They sat in our basement, covered in a thick layer of dust. If books and papers could wonder, they'd wonder why they were still under our stairs after all those years. When would the Big Day come?Well, the Big Day eventually did arrive; only it was different than expected. My wife, always more accepting changes than I am, finally talked me into clearing out the entire mess.The pain I experienced was also unexpected. What hurt me was to come across those terrible papers I'd written, which reminded me of my poor study habits, and an embarrassing lack of comprehension. It was great to get rid of them. But it was also a clearing of personal history.At first, I struggled with this. The truth was in the record that my books, my notes, and my papers were primary source materials, documenting an important time in my life. To clear them out was to clear out the truth.What I've learned since taking this leap is that the process is more important than the truth. I feel as if much of my real education during my college years isn't in the documents but now in me.So I am glad to free myself of this physical burden. And what's better is that I don't need to look back to those painful moments. They belong to the past.You might want to consider doing something similar, either under the stairs of your basement or in your mind.What is the personal rubbish piling in your life? Clear it out and make your life awesome.语篇解读：本文是一篇夹叙夹议文。
