Unit 4 Global warming课时跟踪练（一）Warming Up & Reading-PrereadingⅠ.阅读理解AYou might think that “global warming” means nothing more than a rise in the world's temperature. But rising sea levels caused by it have resulted in the first evacuation (撤离) of an island nation the citizens of Tuvalu will have to leave their homeland.During the 20th century, the sea level rose 8－12inches. As a result, Tuvalu has experienced lowlandflooding of salt water that has polluted the country'sdrinking water.Paani Laupepa, a Tuvaluan government official,reported to the Earth Policy Institute that the nation has suffered an unusually high number of fierce storms in the past ten years. Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging storms.Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol, an international agreement calling for industrialized nations to reduce their greenhouse gas emissions (导致温室效应的气体排放), which are a main cause of global warming. “By refusing to sign the agreement, the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years.” Laupepa told the BBC.Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries.Tuvalu is not the only country that is vulnerable (易受影响的) to rising sea levels. Maumoon Gayoon, president of the Maldives, told the United Nations that global warming has made his country of 311,000 an “endangered nation”．语篇解读：本文主要讲述了全球变暖对于某些岛国，特别是Tuvalu造成的恶劣影响。

Unit 4 Global warmingⅠ.阅读理解AWildfires and heat waves have been troubling the states of California and Arizona this year. Since 2010, about 6.4 million acres have been burned on average per year. Recent studies have stated that global warming is the cause of these wildfires and higher temperatures, and that the incidence of these natural disasters is likely to increase.As temperatures increase, wildfires become more common. As this cycle progresses, climate change and wildfires both increase frequently and seriously. Forest fires are also developing at higher frequencies as a result of global warming. Firefighters use techniques like back-burning to help prevent further spread of these fires, but these measures are not always effective.Some factors that promote wildfires, such as drought and insect outbreaks, have been linked to global warming as well. Insects that kill trees and other plants make the remains more sensitive to fires, as the plant matter dries out and can more easily be burned. Higher temperatures that result from climate change cause more water to evaporate(蒸发)from reservoirs and lakes, which can lead to drought.With global warming causing higher temperatures, the wildfire seasons of affected areas lengthen. This occurs because summer heat begins to build earlier in the year, and the cooling fall season is delayed. For forests in the southwest United States, the conclusion of snow’s melting indicates the time when fires are able to start. Climate change has caused the melting of snow to occur earlier than it did 50 years ago by about one to four weeks.The global warming trend has hit Southern California extremely hard, and the months of January through April have been hotter this year than they have been for any others in recorded history. This has also caused a drought which has been severe or worse for the entire state. Last year, drought affected only 46 percent of California.With the results from these recent studies, global warming has been linked to an environment that promotes wildfires, by creating higher temperatures and causing drought. California’s wildfire season is just starting, and the damages are likely to be worse as the season continues.1. What does the author intend to tell in the passage?A. Global warming causes high temperatures and wildfires.B. Forest fires have been bringing serious threat to the earth.C. High temperatures make water disappear at a high speed.D. California and Arizona are faced with the extreme weather.2. Why are insects connected with wildfire?A. Because tons of insects exist in the forests.B. Because drought drives insets into the forests.C. Because insects leave the trees dead and dry.D. Because the bodies of insects can burn easily.3. We can conclude from the passage that .A. it is impossible to prevent wildfire from happeningB. the southern states in the USA will see the longest summerC. it is necessary to raise awareness of fire preventionD. California has done nothing to fight wildfiresBFred and Bonnie have 21 children. First they had two of their own and they adopted 19 others from countries around the world. They adopted children from many countries, like Japan, India and Vietnam. Each time they made sure they had music, food, pictures, and books of the child's native country so the children would feel good about themselves.Fred and Bonnie had pre-school children running around the house for 26 years without a break! The washer was always going and clothes hung from one end of the room to the other. Everyone helped out with the housework. The family drank ten litres of milk a day.The couple enjoyed their children. They took care of small problems right away so they wouldn't become big problems. Fred says, "If you have trouble with one of your children, don't worry. Worry doesn't help, and in time your child will be all right."When the children were older, Bonnie began travelling to India. She opened three homes for 170 homeless children. She travels there four times a year to bring food, medicine, and used clothing to the needy children.Back home, Bonnie cooks meals for her seven children still living there. The other children keep in touch. When Tran got married,18 brothers and sisters danced at his wedding.They hope their children will find their own way to help others. They want them to be happy, healthy and independent.Fred says, "Let me light my lamp and never wonder if it will take away the darkness."4. What does the word "adopted" underlined in Paragraph 1 mean ?A. raised children with government support.B. looked after children for parents who were busy.C. provided education for children from poor families.D. brought up someone else's child as his parents.5. What did the couple do to make sure that the children felt good about themselves?A. To offer them things from their own country.B. To feed them well.C. To make sure they could play well.D. To handle small problem right away.6. What does Bonnie do after the children grow up?A. She goes abroad to help more children in need.B. She still stays at home to cook for them.C. She set up three homes in Vietnam.D. She often visits her son in India.7. Why do the couple want to live such a life?A. To get extra money from the government.B. To be allowed to build more rooms.C. To have more chances to travel abroad.D. To offer help and to show their love.8. Which of the following is the best title for the article?A. Worry doesn't help.B. A big happy family.C. How to help others.D. Family should keep in touch.Ⅱ.完形填空The back door of the ambulance(救护车)was suddenly shut and the driver ran to the front, jumped into his seat, and started the engine.

Studies by leading research institutions have shown that if we invest in clean energy over fossil fuels, we will create more American jobs. A report released by the United Steelworkers and the Sierra Club, for example, found that thanks to the growth of wind energy, about 5，200 manufacturing jobs could be created in Iowa alone over the next decade. Additional studies have found that thousands more jobs could be created in other states that have suffered industry job losses and that welcome the opportunity to train workers for the new energy economy. But, in order to fully transit to a clean energy economy，we need our elected officials to take action. Without policies from the government, the private field may continue to invest in old－fashioned, polluting technologies. More than 70 coal plants without technology to capture carbon pollution are now being considered. If these projects go ahead, this will be billions of dollars invested in technology that is outdated and not “clean coal”. We need effective policies to push growing clean energy industries forward. Each of us can play a role in bringing about this much－needed transition.Tell your business and elected leaders that the next generation deserves to grow up in a world powered by clean energy. Tell your mayor that you want city planning that encourages more efficient new buildings and sidewalks and bike paths that make it easy to walk or ride a bike. Tell your state and national officials to invest in energy grids (电力网) that can deliver renewable energy to everyone. Tell your company that instead of old－style coal power you want to buy solar, wind, or geothermal energy. Tell your elected officials that you want national policies that encourage investors to make long－term commitments toclean energy. 1．The underlined part “a transformation” in Paragraph 1 refers to“________”．A．a change from fossil fuels to clean energyB．a choice for fossil fuelsC．a chance of developing modern industriesD．a choice for global warming2．According to Paragraph 2, a clean energy economy________．A．has helped develop more wind energyB．is quite beneficial to ordinary peopleC．has developed fast in most states of the USD．is valued by the governments around the world 3．Which of the following is a major concern to the government according tothe passage?A．Investments in clean energy.B．Coal plants without advanced technology.C．Technology for capturing carbon pollution.D．Policies on the good use of clean energy.4．What is Paragraph 4 mainly about?A．Everyone can contribute to the clean energy.B．Citizens have the right to talk to the mayor.C．Elected leaders should be responsible for the next generation.D．More investments should be put into energy grids.5．If this passage is taken from a newspaper, in which part would you mostprobably find it?B．Society.A．Culture.D．Nature.C．Economy.BBeijing had its biggest snowfall since 1951.Britain is suffering through its longest cold snap(寒潮)since 1981.And freezing weather is hitting the DeepSouth，including Florida's orange groves and beaches.Whatever happened to global warming?Such weather doesn't seem to fit with warnings from scientists that the Earth is warming because of greenhouse gases. But experts say the cold snap doesn't contradict global warming at all—it's just a temporary phenomenon in the long－term heating trend.“It's part of natural variability，”said Gerald Meehl，a senior scientist. With global warming，he said，“we'll still haverecord cold temperatures. We'll just have fewer of them.”Scientists say man－made climate change does have the potential to cause more frequent and more severe weather extremes. But experts did not connect thecurrent cold snap to climate change.So what is going on?“We basically have seen just a big outbreak of Arctic air over populatedareas of the Northern Hemisphere”，Arndt said.In the atmosphere，large rivers of air travel roughly west to east aroundthe globe between the Arctic and the tropics. This air flow acts like a fence to keep Arctic air restricted. But recently，this air flow has become bent into a zigzag(之字形)pattern，wandering north and south. If you live in a place where it brings air up from the south，you get warm weather. In fact，record highswere reported this week in Washington state and Alaska. But in the eastern United States，like some other unlucky parts of the globe，Arctic air is coming from the north. And that's how you get a temperature of 3 degrees in Beijing，a reading of minus－42 in mainland Norway，and 18 inches of snow in parts of Britain. The zigzag pattern arises naturally from time to time，but it is not clear why it's so strong right now.6．What is the BEST title of the text?A．Freezing weather is hitting the Deep SouthB．We'll still have record cold temperaturesC．The air flow has become a zigzag patternD．Cold snap doesn't contradict global warming7．With global warming，we will________．A．also meet with severe cold snapB．have more hot temperatures foreverC．never experience cold temperaturesD．have more cold temperatures8．According to experts，the current cold snap ________．A．suggests that the climate has changed greatlyB．is not related to the climate changeC．shows that the climate will turn coldD．is affected by global warming 9．Beijing had its biggest snowfall since 1951 because of ________．A．a fence from the ArcticB．a cooling trend in climateC．a big outbreak of Arctic airD．its large population10．We can conclude that________．A．not all the parts of the Northern Hemisphere are cold in face of the coldsnapB．the zigzag pattern arises naturally accidentallyC．Beijing will get cold weather next year D．Washington state and Alaska will not face cold weather next yearⅣ.翻译句子1．我想火车是正午开，你最好坐出租车去，否则可能会误车的。

Unit 4 Global warmingⅠ.阅读理解(2017·会宁一中月考)Is there link between humans and climate change or not? This question was first studied in the early 1900s. Since then, many scientists have thought that our actions do make a difference. In 1997, the Kyoto Protocol explained our role in the Earth's changing atmosphere and set international limits for gas emissions(排放) from 2008 to 2012. Some countries have decided to continue these reductions until 2020. More recently, the Paris Agreement, stuck by nearly 200 countries, also aims to limit global warming. But just now how much warmer it will get depends on how deeply countries cut carbon emissions.1．It can be concluded from paragraph 1 that ________.A．the problem of global warming will have been quite solved by 2020B．gas emissions have been effectively reduced in developed countriesC．the Paris Agreements is more influential than the Kyoto ProtocolD．humans have made continuous efforts to slow down global warming2．If nations could only keep the initial promises of the Paris Agreement, what would happen by the year 2100?A．The human population would increase by one third.B．Little over 50% of all species would still exist.C．Nations would not need to tighten their emissions targets.D．The Agreement's minimum goal would not be reached.3．If those island nations not far above sea level are to survive, the maximum temperature rise, since the start of the industrial age, should be ________.A．0.8 ℃B．1.5 ℃C．2 ℃ D．3.5 ℃答案与解析本文介绍了人们一直努力减少温室气体的排放，并设立了到2100年我们应该达成的目标以及达成目标要符合的条件。

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。

Salt water is already entering the country’s drinking water supply, as well as damaging plants that produce fruit and vegetables. Without urgent help, the country’s days are numbered.But Tuvalu is not the first place to face sinking into the sea. Venice, a historic city in Italy best known for its canals, has sunk about 24cm over the past 100 years. Experts say that it will have sunk another 2050cm by 2050. A century ago, St. Mark’s Square, the lowest point city, flooded about nine times a year. Nowadays, it happens more than 100 times. While Venice is slowly sinking into the mud on which it stands, global warming causes Tuvalu’s rising sea level.The average global temperature has increased by almost 0.5 centigrade degrees over the past century; scientists expect it rise by extra 13 degrees over the next 100 years.Warmer weather makes glaciers (冰川) melt, adding more water to the ocean. The warmer temperatures also make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen about 1025 cm in the last 100 years.The main cause of global warming is human pollution. Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO2. This adds to the power of the greenhouse effect, making the planet even warmer.Many scientists believe that, if the warming is not stopped, there will be huge climate changes. The sea level could rise by one meter this century.Should this come true, the sea will swallow up millions of homes and the world will be flooded with “climate refugees” looking for somewhere to live.1. We can infer from the second paragraph that________.A．Tuvalu is in danger of being swallowed up by the seaB．all Tuvalu’s islands are about five meters above the sea levelC．drinking water in Tuvalu has been destroyedD．Tuvalu is often flooded by storms and waves2．The author uses Tuvalu and Venice as examples in order to explain________.A．they are the first place sinking into the seaB．they are both sinking into the mud where they standC．they will disappear in the futureD．their trouble is caused by the global warming3．Put the following events in the right order.a．Glaciers began to melt.b．People burn coal, oil and gas.c．The greenhouse effect is growing.d．The earth is getting warmer and warmer.e．The sea level is rising.f．More CO2 is produced.g．Many places are sinking into the sea.A．d, f, b，c, a, e, g B．b, f, c, d, e, a, gC．f, c, b, d, a, e，g D．b, f, c, d, a, e, g4.

These environmental pollutants (污染物) bring new problems and affect human health，” Zhang told a news conference.He said that emissions (排放) of traditional pollutants remain high and some areas have failed to meet government standards.The minister noted that rapid development in the next five years would increase the need for China to improve environmental protection and shift to a more sustainable model of economic development from its dependence on industries which consume huge quantities of energy.China is focusing on clean energy, including solar, wind and nuclear power, as one way to reduce its dependence on coal, which generates threequarters of its electricity and is also used for winter heating in northern cities. China also hopes the strategy will reduce its demand for oil and gas and increase economic growth and jobs.Zhang told reporters there was no plan to adjust China’s overall strategy for nuclear development but he said Beijing will learn lessons from Japan after a violent earthquake resulted in a radioactive leak (放射能泄露)．“Some lessons we learn from Japan will be considered in the making of China’s nuclear power plans，” he said. “But China will not change its determination and plan for developing nuclear power.”6．According to the minister, the pollution problem requires China to________.A．slow its economic developmentB．ask industries to meet government standardsC．protect the environment firstD．transform its economic development model7.According to the text, which of the following is TRUE?A．Rapid economic growth helps to improve the environment.B．Dangerous chemicals are one of the traditional pollutants.C．Coal is used more in northern cities than in southern cities.D．The use of clean energy will help increase job opportunities.8．The underlined word “generates” in Paragraph 6 means“________”．A．reduces B．transports C．produces D．needs9. What do the last four paragraphs mainly talk about?A．Japan had a violent earthquake recently.B．China will learn to use nuclear power from Japan.C．Rapid economic growth caused some problems in China.D．China’s economic development will shift to depend on clean energy.10. What is Zhang’s attitude towards what happened in Japan?A．He is astonished at it and feels pity for the Japanese people.B．He thinks Japan should do something to prevent it happening again.C．He thinks China will pay more attention to nuclear safety.D．He doesn’t think it will affect China’s nuclear power plans at all.参考答案Ⅰ.选词填空1. subscribe2. quantities3. tend4. opposed5. state6. range7. glanced8. steady9. random 10. consequencesⅡ.单项填空1. 选C。

Unit 4 Global warming【导语】全球气温变暖给南极的企鹅带来了怎样的影响，你知道吗？为了保护他们，我们应该怎么做？Antarctica, the coldest place on Earth, is too cold for most humans.It's a different story for penguins，though.Several types of penguins make their home in Antarctica.The birds walk with short steps all over the icy continent.However，they don't all have “happy feet”．Some of Antarctica's penguins are endangered.The animals, hunt for food in waters off Antarctica's coasts.They use floating sea ice as a place to rest while they search.In recent years, global warming, the slow rise of Earth's temperature, has been causing the ice to melt.“Global warming is reducing the amount of food for penguins so that they can't find enough to eat, ”scientist Shaye Wolf said.Turning up the heatPeople add to global warming when they drive cars or use electricity.That burns fossil fuels, such as coal，oil，and natural gas.The burning of fossil fuels gives off gases that warm Earth.The harmful gases stay in the atmosphere above Antarctica, researchers say.They found that the west side of the continent is especially affected by global warming.Scientists are concerned about the possibility that Antarctica's ice may melt more over time.The icy continent is about 5 million square miles.It is covered by glaciers and an ice cap (冰冠) about 7，100 feet thick.If the ice melts, that could cause sea levels to rise around the world.Higher sea levels could lead to dangerous flooding in some countries.Cool fix for AntarcticaExperts are hopeful that conditions in Antarctica can be improved.They say people can reduce global warming by using cars and electricity less often.Even kids can help.Wolf suggests，“Talk to your friends and family about global warming, how it is harming penguins, and how important it is to stop global warming today.”【词海拾贝】1．Antarctica n．南极洲2．penguin n．企鹅3．fossil n．化石；生物4．glacier n．冰河；冰川【问题思考】1．Why can't penguins find enough food to eat?_______________________________________________________答案：Because global warming is reducing the amount of food for them. 2．Who may be directly responsible for global warming?_______________________________________________________答案：Humans.Ⅰ.将单词与其正确释义连线1．consume A．图表；曲线图2．graph B．现象3．phenomenon C．燃料4．fuel D．平均的5．trend E．趋势；倾向6．mild F．温和的；温柔的7．consequence G．环境；情况8．circumstance H．贡献9．average I．消费；消耗10．contribution J．结果答案：1－I 2－A 3－B 4－C 5－E 6－F 7－J8－G 9－D 10－HⅡ.根据所给汉语提示写出单词1．____________ n．洪水；水灾2．____________ vt.反对；反抗3．____________ adj.平稳的；持续的4．____________ adj.分布广的；普遍的5．____________ vt.拥护；提倡，主张6．____________ n．污染；弄脏答案：1.flood 2.oppose 3.steady 4.widespread5．advocate 6.pollutionⅢ.根据英语释义写出单词1．________： a quick look2．________：an amount or a number of sth3．________：to pay money regularly to support a charity4．________：to express something in speech or writing，especially in a definite or formal way5．________：happening or chosen without any definite plan，aim or pattern6．________：to take a particular direction7．________：a sudden event resulting in great loss andmisfortune8．________：the limits between which sth varies；a set ofproducts of a particular type答案：1.glance 2.quantity 3.subscribe 4.state5．random 6.tend 7.catastrophe 8.rangeⅣ.选用短语的适当形式完成句子keep on；be opposed to；come about；result in；subscribe to；go up；quantities of；even if1．There are large _______________________________ rain in this area.答案：quantities of2．Do you know how global warming ____________________?答案：comes about3．I have never ________________ the view that schooldays are the happiest days of your life.答案：subscribed to4．If you want to make the kite __________________， pull the string hard，and then release it slowly.答案：go up5．His careless speech ____________________________ much argument.答案：resulted in6．We ___________________ the practice of power politics between nations.答案：are opposed toⅤ.领会句子所用的句型并译成汉语1．That probably does not seem much to you or me，but it is a rapid increase when_compared_to other natural changes.______________________________________________________________________________________________________________答案：这个数值对你我来说可能是无所谓的，但是跟其他自然变化相比较而言，这却是一种快速的增长。
