2019-2020年高中英语 Unit4 Global warming参考译文 新人教版选修6
2019-2020年高中英语 Unit4 Global warming参考译文新人教版选修6在20世纪期间，地球温度大约升了华氏1度。
这个数值对你我来说很可能是无所谓的，但是，跟多数自然变化相比较而言，这却是种快速的增长。
这种温度的增长是怎么产生的呢？“关爱地球”组织的索菲·阿姆斯特朗就在探究这些问题。
毫无疑问，地球是在变暖。
但是全球变暖的原因是人为的呢，或者仅仅是一种自然现象呢？对于这个问题存在着激烈的争辩。
许多科学家认为，人们为了生产能量而燃烧化石燃料（如煤、天然气和石油等），从而引起了地球温度的升高。
这个升温过程的副产品就叫做“温室”气体，其中最重要的就是二氧化碳。
贾尼丝·福斯特博士解释说：“你知道，有一种科学称之为‘温室效应’的自然现象。
这种现象发生在大气层中少量的气体（如二氧化碳、甲烷、水蒸气等）吸收太阳的热量，因而，使地球变暖。
如果没有这种‘温室效应’，地球的温度将比现在的温度还要低33摄氏度左右。
因此，我们需要这些气体。
而当我们因为燃烧化石燃料而使大气层中增加了大量额外的二氧化碳时，问题就来了。
二氧化碳含量的增加意味着更多的热量被困在大气层中，从而引起了全球温度上升。
我们知道，在过去100~150年期间，二氧化碳的含量急剧增加了。
有一位名叫查尔斯·奎林的科学家曾经把1957~1997年期间大气层中二氧化碳的含量做了精确的统计。
他发现，在这些年里，大气层中的二氧化碳含量从百万分之三百一十五上升到百万分之三百七十。
所有科学家都接受这个数据。
他们还认为，正是由于燃烧的化石燃料越来越多而导致了二氧化碳的增加。
然而，科学家们在对待这个问题的态度上却是大不相同的。
贾尼丝·福斯特博士说，在今后的100年里，全球变暖的量可能低到1~1.5摄氏度，但是也有可能高达5摄氏度。
有多么糟糕呢？有人认为，全球变暖会导致海平面上升好几米；也有人预言会出现严重的风暴、干旱、饥荒、疫病和物种的绝灭。

The global averagesurface temperature rose 0.6 to 0.9 degrees Celsius (1.1 to 1.6°F) between 1906 and 2005, and the rate of temperature increase has nearly doubled in the last 50 years. Temperatures are certain to go up further.Earth’s natural greenhouse effect Earth’s temperature begins with the Sun. Roughly 30 percent ofincoming sunlight is reflected back into space by bright surfaces like clouds and ice. Of the remaining 70percent, most is absorbed by the land and ocean, and the rest is absorbed by the atmosphere. The absorbedsolar energy heats our planet. As the rocks, the air, and the seas warm, they radiate “infrared radiation). From the surface, this energy travels into the atmosphere where much of it is absorbedby water vapor and long-lived greenhouse gases such as carbon dioxide and methane. When they absorbthe energy radiating from Earth’s surface, microscopic water or greenhouse gas molecules turn into tiny heaters— like the bricks in a fireplace, they radiate heat even after the fire goes out. They radiate in alldirections. The energy that radiates back toward Earth heats both the lower atmosphere and the surface,enhancing the heating they get from direct sunlight. This absorption and radiation of heat by the atmosphere—the natural greenhouse effect—is beneficial for life on Earth. If there were no greenhouseeffect, the Earth’saverage surface temperature would be a very chilly -18°C (0°F) instead of the comfortable 15°C (59°F) that it is today.What has scientists concerned now is that over the past 250 years, humans have been artificiallyraising the concentration of greenhouse gases in the atmosphere at an ever-increasing rate, mostly byburning fossil fuels, but also from cutting down carbon-absorbing forests. Since the Industrial Revolutionbegan in about 1750, carbon dioxide levels have increased nearly 38 percent as of 2009 and methanelevels have increased 148 percent.II.拓展提高书面表达如何解决全球变暖是我们全人类共同面临的一个难题。

连词成篇Unit 4. Global WarmingRefresh Our EnvironmentAs the director state d on behalf of his research ing group, the data of this graph makes a clear presentation of the future environmental tendency. On one hand, the quantity of fuel keeps on decreas ing by 9% per year while the growth of a wide range of pollution has been a global trend. On the other hand, the mildly but steadily going up of the average temperature is resulting in catastrophe s like widespread floods. Without disagreement, they subscribe to the view that it is humans’existence and their randomly consum ing energy that result in this phenomenon.Many people have a commitment that developing nuclear power or energy from outer space will stop bad consequence s coming about. However, scientists and educators are opposed to this view even if our needs may be met on the whole. They tend to advocate refresh ing our circumstances by saving energy and recycl ing waste. It is suggest ed that we use energy-saving appliance s such as electrical motor s, microwave s and so on and not be casual about little things like recycl ing a can.

AThe number of buses, taxis and other vehicles on Kenya’s roads is growing every day. Now, the country’s first electric-powered motorbikes are coming into the market. The bike is designed to cut down on pollution and aimed at low-income communities. Most motorbikes used in Kenya depend on gasoline as fuel, but not this new motorbike.Three university students developed the new ecotype bike. It catches the sun’s energy, stores it in batteries and uses it to charge the electric motor. Robert Achoge is one of the student inventors. “Our hope is that by th e fifth year, we will be able to cover the whole of Kenya with the electric motorcycle so as to conserve the environment and provide affordable transport.”The students have set up a charging station for the motorbikes in Nairobi. Riders can plug the bikes into any electrical outlet. The small battery can run for 70 kilometres when fully charged. Once the power is used up, the motorbike has to return to the station while another charged battery is connected to the bike. The US African Development Foundation (USADF) is providing finance for two solar-powered charging stations in the Kenyan port of Kisumu.Each ecotype bike costs about $700. One taxi operator says the new motorbike costs less to operate than that running on traditional gasoline. “When it comes to buying gasoline, there’s no need. It’s basically good for various things. As long as you won’t take quite a heavy load(装载量), you can go with it anywhere. Otherwise, it may break down halfway. But now people still have a preference to the gas-powered bi kes.”A Nairobi dealership is selling the ecotype bikes. Businessman Kennedy Kusimba hopes they will become popular. We also know they are more reliable compared to the gas-powered bikes.1.What do we know about the ecotype bike?A.It was developed by the USADF.B.Its energy comes from the sunlight.C.It can charge itself while running.D.It does more harm to the environment.2.What do people think of the ecotype bike?A.It’s better not to use it to carry too much.B.It is a good choice for the long-distance journey.C.It will take the place of gas-powered bikes soon.D.It is much more expensive than a traditional motorbike.3.Where does the text probably come from?A.A research plan.B.An advertisement.C.A government report.D.A science magazine.BSeveral years ago, the mayor of Chicago, Illinois, visited Germany, a leader in green roof design. Former Mayor Richard Daley later decided to have vegetation planted on Chicago City Hall. Today, the tops of many other buildings also look like parks. In Canada, the Coast Plaza Hotel in Vancouver has a forest on its roof. New York City has an unusual demonstration farm for hydroponics(水培).The farm is on a boat called the Science Barge. Rainwater and purified river water are used to grow lettuces, tomatoes, cucumbers and peppers. The farm shows the possibilities for designing rooftop systems.Green roofs are designed to save energy and capture rainwater. Rooftops covered with plants help keep buildings cool. They can extend the life of a roof. And they can reduce water running off into streets and storming water systems.Experts say green roofs usually do not get much above twenty-seven degrees Celsius. So temperatures might not be a problem for growing. But rooftop gardeners have to be careful not to put too much weight on the roof. This is true whether plants are grown in soil or water.Earlier in 2008, researchers in Texas reported that green roofs can reduce a building’s air conditioning costs by about one fifth compared to blacktop roofs. But they also reported that not all green roofs perform equally well. They found that designs differ in their ability to keep buildings cool and to capture rainwater. The researchers put experimental roofs on top of metal insulated boxes, to recreate green roof conditions. The study compared products from six companies to help businesses understand how to improve their designs. Each rooftop had sixteen different kinds of plants native to Texas. The researchers said the presence of native plants likely helped all the green roofs capture water better compared to sedums. Sedums are plants that need little water and often are used on green roofs. The native plants could take in more water and release more of it to the atmosphere.4.The author writes Paragraph 1 to .A. tell us what is the green roof designB. tell us Germany is the country that leads or guides the green roof designC. introduce some famous hotels in the worldD. lead to the topic of the passage5.The underlined word “storming” in Paragraph 2 can be replaced by “”.A. attackingB.controllingC.attractingD.managing6.According to the passage, which conclusion is WRONG?A. Sometimes green roofs may break down the house.B. Not all the green roofs can reduce the building’s air conditioning costs equally.C. Different designs of green roofs have different effects on buildings.D. Sedums are a kind of plants native to Texas.CThe Antarctic’s ice-white environment is going green and facing other unexpected threats. Scientists say that as temperatures go up in the polar region, invading (入侵) plants and insects, including the flies, cause a major threat.More and more of these invaders, in the form of larvae (幼虫) or seeds, are surviving in coastal areas around the South Pole, where the temperature has risen by more than 3℃over the past three decades. Glaciers have retreated, exposing more land which has been occupied by mosses that have been found to be growing more quickly and thickly than ever before—providing potential green homes for invaders.“The common house flies are a perfect example of the problem the Antarctic now faces from invading species,” said Dominic Hodgson of the British Antarctic Survey. “It comes in on ships, where it exists in kitchens and then at bases on the continent. It now has an increasing chance of surviving in the Antarctic as it warms up, and that is a worry. Insects like the house flies carry bacteria that could have a deadly effect on native life forms.”The Antarctic has several native species of insects. Together with its native mosses, these are now coming under the increased threat from three major sources: visiting scientists, increasing numbers of tourists and global warming. However, it is global warming that is the main driver of the greening of the Antarctic.In 2015, more than 38,000 tourists visited the Antarctic. “These tourists are often very careful about not leaving waste or having mud. But they could carry seeds or larvae on their boots when they set foot on the Antarctic,” said Hodgson.More and more invasive insects and plants have been found on the Antarctic and have required removal. “The insects and plants that are native to the Antarctic have survived there for thousands of years,” said Hodgson. “We have got to act now if we want to save the environment.”7.What does the underlined word “mosses” in Paragraph 2 refer to?A. A kind of plants.B. House flies.C. Coastal areas.D. A kind of animals.8.What is the main cause of the Antarctic going green?A. Scientists’ coming.B. Global warming.C. A growing number of visitors.D. The rapid spread of native planting.9.What do we know about the house flies in the Antarctic?A. They are native to the Antarctic.B. They will disappear due to the cold climate.C. They seriously affected the Antarctic native species.D. They directly fly to the Antarctic from nearby islands.10.What’s the best title for the text?A. The Antarctic is faced with various threatsB. The Antarctic is becoming green and energeticC. More and more scientists get to explore the AntarcticD. Global warming has caused the temperature in the Antarctic to rise up第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

英语：Unit 4 《Global Warming 》教案-reading （新人教版选修6）Period 2 Pre-reading, Reading, ComprehendingTeaching Goals:1.To read about global warming.2.To get some idea about the effect of global warming.3.To develop some basic reading skills.Teaching Procedures:Step 1. Warming UpPurpose: To arouse Ss interest in learning about global warming.1. Team workAnswer the questions below:(1) Have you ever seen a greenhouse?(2) How does a greenhouse work?(3) What do you think greenhouse gases do?2. Group workLook at the picture, and ask Ss some questions.T: What is this building made of?S1: It’s made of plastic.T: What’s its purpose?S2: Plants can grow in it when it’s cold outside.T: How does it work?S3: The glass traps the heat from the sun, making the air warm so that plants grow better.Step 2. Pre-readingPurpose: To get Ss to learn about greenhouse gases.1. Group workNow look at the word “GREENHOUSE GASES”. What does it mean?Greenhouse gases (GHG) are gaseous components of the atmosphere thatcontribute to the greenhouse effect .The major natural greenhouse gases are watervapor, which causes about 36-70% of the greenhouse effect on Earth (not includingclouds): carbon dioxide, which causes between 9-26%; and ozone, whichcausesbetween 3-7%(note that it is not really possible to assert that such-and-such a gas causes a certain percentage of the GHE, because the influences of the various gases are not additive .The higher ends of the ranges quoted are for the gas alone ;the lower end ,for the gas counting overlaps).Naturally occurring greenhouse gases include water vapor, carbon dioxide, methane, nitrousoxide, and ozone. Certain human activities, however, add to the levels of most of these naturally occurring gases.Very powerful greenhouse gases that are not naturally occurring include hydrofluorocarbons(HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6), which are generated in avariety of industrial processes.Each greenhouse gas differs in its ability to absorb heat in the atmosphere. HFCs and PFCsare the most heat-absorbent.2. Individual workGet Ss to answer these questions individually. Then let them discuss the answers.(1) Who wrote the magazine article? What is the name of the magazine?(2) What are the names of the three scientists mentioned in the article?(3) What do they think about global warming? Do they agree with one another?(4) What are the two graphs about?(5) What is the main topic of the article?Step 3. Reading1. SkimmingPurpose: To get a brief understanding of the text.Read through the text, preferably the first and the last sentences of each paragraph and write the key sentence of each paragraph.Key sentences of each paragraph:(1) A debate over whether it is human activity that has caused the global warming or whether it is just a naturalphenomenon.(2) Many scientists believe people have caused the increase in the earth’s temperature.(3) The increased extra amount of carbon dioxide traps more heat energy causing the global temperature to go up.(4) The levels of carbon dioxide have increased greatly over the last 100 to 150 years.(5) There are some different attitudes towards the causes of this increase in carbon dioxide.(6) Over the next 100 years the amount of warming could be as low as 1 to 1.5 degrees Celsius but it could be asmuch as 5 degrees Celsius.(7) An increase of five degrees would be a catastrophe.(8) Future warming would cause the sea level to rise by several meters.(9) Some predict any warming will be mild with few bad environmental consequences.(10) More carbon dioxide is a positive thing.(11) No one knows what the effects of global warming will be.2. ScanningPurpose: To get Ss to have some details in the text.Read the article carefully. Are these statements true or false? Write a T for each true sentence and an F for each false sentence.(1) The temperature last century didn’t increase much. ( )(2) Everyone believes that global warming is caused by the activities of humans. ( )(3) Janice Foster believes that burning fossil fuels causes global warming. ( )(4) Natural gas is a greenhouse gas. ( )(5) Carbon dioxide is a byproduct of burning fossil fuels. ( )(6) People accept Charles Keeling ’s data because he took accurate measurements.

It’s not that Ben is unsociable , or a bad cook , but it’s just that he never 37 more than he has to. So how come he was inviting us round for a meal? Had he bought something 38 for his friends? He greeted us at the door and showed us into his dinning room where a 39 table was waiting for us.“Nothing but the 40 for my friends!”said Ben. We all sat down and looked 41 at each other—what did he 42 to?Ben returned with four bowls of hot soup.“It’s a 43 of carrots , potatoes and tomatoes,”said Ben. The next 44 was also a little strange in that we didn’t quite know what it was again.It’s just 45 mixture of vegetable.As we ate we chatted and finally the 46 turned back to what we were eating.“Was there a recipe（食谱）for this,”asked Marina ,“or did you 47 it up?”Ben put his fork down. “What I cooked 48 what I could find.”Marina was surprised.“But you can find anything in supermarkets these days.”“But there’s 49 choice in what you can find 50 supermarkets.”He replies.51 that we had all finished the food , Ben decided to tell the truth. He had read recently that supermarkets usually 52 away 5 percent of their food every day. So Ben decided to look inside his local supermarket bins. There he found food that was slightly out of 53 , boxes of throw-away vegetables and fruit.So Ben had 54 provided a decent(不错的) meal for his friends , and made us away of the fact that there are many poor people who need the food , but the amount of food thrown away is enough to 55 millions of people.36.
