Warming Up & Reading — Prereading
Kiribati has been an independent nation since 1979. Although like much of the Pacific, Kiribati is poor, the country has plenty of foreign money to buy a new land. The money comes from mining on the islands in the 1970s.
Reuters — Fearing that climate change could wipe out their entire Pacific islands, the leaders of Kiribati are considering an unusual support plan: moving the population to Fiji. According to Kiribati President Anote Tong, his government agreed on a plan to buy nearly 6,000 acres(英亩) on Fiji's main island, Viti Levu. The rich land, being sold by a church group for about D|S9.6 million, could be enough for Kiribati's entire population of 103,000. “We wouldn't put everyone on one piece of land, but if it became absolutely(完全地) necessary, yes, we could do it，” Tong said. “For a younger generation, moving won't be a matter of choice but basically a matter of survival.”
高中英语Unit 4 Global warming-section 2
Unit 4 Global warming-section 2Part Two: Teaching Resources (第二部分：教学资源)Section 2: Background information on THE EARTH ISBECOMING WARMER—BUT DOES IT MATTER?I. What is global warming?Global warming is the name of the theory (idea) that the world's atmosphere (air) has become hotter over the last two hundred years. It is also used as the name of this event (an event is sth. that happens). Some people say that global warming is a very serious problem for the world, that it causes floods for example. Others say that there is nothing for the world to worry about.It is a fact that the atmosphere of the world is in general about a half of a degree Celsius hotter than it was two hundred years ago. But many people disagree about whether this is caused by man's pollution (from cars and factories for example), or a natural change.II. What is greenhouse effect?The greenhouse effect is a way that the sun's rays make sth. warmer.A greenhouse is a glass or plastic building where people raise plants. The rays of the sun shine into the greenhouse and become warmth. The glass or plastic holds the warmth inside the greenhouse.We can also see the greenhouse effect when the sun makes the inside of a car hot. Many people are very interested in the greenhouse effect in the atmosphere of the Earth. Factories, farms, and other things that human beings do make many different gases that go into the Earth's atmosphere. The gases carbon dioxide, methane, and chlorofluorocarbons make the atmosphere hold more of the sun's heat, so the Earth might get warmer. If the Earth does get warmer, this could cause many serious problems. Different parts of the Earth could become warmer or colder, wetter or drier. The ice at the north and south poles could melt, which would make the sea level higher, and flood many cities that are close to the sea.Scientists, politicians, and ordinary people disagreeabout what is happening and what might happen. Scientiststhink that weather has been especially warm the last fewyears, but they disagree about whether this warming iscaused by the things that human beings are doing or is happening naturally.III. What is Earth Care International?Earth Care builds the awareness, knowledge, and commitment inyouth necessary to create a healthy, sustainable future. Ourapproach is based on the recognition that sustainability canonly be achieved by linking issues of economics, socialjustice, and the environment infused with a multiculturalawareness.We develop young visionary leaders capable of creating an abundant and sustainable world. These visionary leaders will make choices that will improve their relationship to the environment, one another and ultimately the world.We educate youth to understand the local and global connections between human and natural systems.“A movement that's courageous and visionary on the environment but cowardly and ignorant about the social issues, will fail. And on the other side, a movement that is visionary and passionate on the social side but is ignorant and indifferent on the ecological side will also fail. There's a light at the crossroads. Hope is at the crossroads.”IV. Celebrate Earth Day's 35th Anniversary! “地球日”三十五周年纪念！On April 22, 1970, 20 million people across America celebrated the first EarthDay. It was a time when cities were buried under their own smog and pollutedrivers caught fire. Now 35 years later, Earth Day is being celebrated aroundthe globe. Through the combined efforts of the U.S. government, grassroots organizations, and citizens like you, what started as a day of national environmental recognition has evolved into a world-wide campaign to protectour global environment.V. Earth Day background informationOur planet is a complex system of land, air, and water. Living things depend on each other and this system for existence. Over the thousands of years since life has existed on the earth, it has undergone some changes. The following are some of these changes:Many species became extinct before mankind made its appearance, however, since humans have existed on the earth, the extinction rate has risen dramatically. More than 4,000 species are currently considered threatened. Plant and animal life become endangered for many reasons. Forest depletion, hunting, and pollution are the most obvious factors. When an animal becomes endangered, dozens ofother species can also become endangered. For example, elephantsdisappeared from southern Africa about 80 years ago because ofhunters. Elephants continue to be hunted, mainly for their costlyivory tusks. The endangerment of elephants also has endangeredsuch animals in their area as wildebeest and antelope who live offof the open-grassland which elephants create by eating their way through a jungle.Oxygen-producing trees and plants are being cut down for the purpose of growing foods, grazing livestock, making paper products, etc. The cutting down of forests puts forest wildlife at risk and decreases the oxygen in the air. It also defaces the natural beauty of the planet. Tropical rain forests are often cleared for farming. The soil in these forests are poor in nutrients, and within a few years the crops fail and the land is abandoned. New forests are cleared.Pollution has become more and more a problem, especially in the past century withthe drastic increase in technology. Garbage, sewage, chemicals, and oil are being dumped into the ocean. As human population grows, people are looking to the ocean more for resources. Landfills and littering have polluted the land. Dangerous levels of chemical emissions from cars, planes, factories, aerosol cans, etc., enter the air without end. Plants and animals are dying because of pollution.Ozone is a form of oxygen that has collected in a layer about 30 km above the earth's surface. This ozone layer protects us from most of the dangerous ultraviolet radiation from the sun. Without this layer, living things could not thrive onthe earth. Satellites have detected in the last ten or so years damage doneto the ozone. The damage is often referred to as a hole in the ozone. This damagehas been caused by certain chemicals being emitted into the atmosphere that react with the ozone. One major chemical is called chlorofluorocarbons (CFCs), which are commonly used in such products as solvents used for cleaning electronics such as television and computer circuit boards, cooling fluid in automobile air conditioners, aerosol spray cans, etc. Ozone depletion has effected the temperature of the earth. Some scientists say that if CFCs were not in existence, the earth would be cooler now than it presently is. This global warming is often called the greenhouse effect.Environmentalists have been actively aware of these issues, and are doing their best to promote awareness. In the late sixties, Senator Gaylord Nelson of Wisconsin first suggested the idea of an Earth Day to bring people to the realization that Earth has some problems, and we as humans need to do something about it. The first Earth Day celebration took place on April 22, 1970. It was a nationwide focus. Twenty-million Americans joined in to proclaim the message, “Give Earth a Chance.”A series of events took place on a community level, most of which were organized by student groups. Since then, Earth Day has expanded. The tenth anniversary of the celebration in 1980 was sponsored partly by The United States Environmental Protection Agency. The twentieth anniversary in 1990 was sponsored by hundreds of environmental organizations across the nation. Every year on April 22, all Americans are asked to celebrate Earth, to take a look at what is being done to help our ecosystem, and to ask ourselves, “What am I doing to help?” Many people use the day to plant flowers or trees, clean up communities, promote recycling, forest and wildlife protection, etc., and look to the future of the earth.。

Out of the 23 models now available, the new predictions are based on the six most suited for assessing sea ice, according to Muyin Wang, a university of Washington climate scientist, and James Overland, an oceanographer. Wang and Overland sought models that best matched what has actually happened in recent years, because, “if a model can't do today's conditions well, how can you trust its future predictions？” Wang says.

Unit 4 Global warmingPart Two: Teaching Resources (第二部分：教学资源)Section 1: A text structure analysis of THE EATH IS BEING W ARMER—BUT DOES IT MATTER?I. Type of writing and summary of the textII. A diagram of the textIII. A retold version of the textA debate is going on over whether it is human activity that has caused the global warming or whether it is just a natural phenomenon.Many scientists believe that it is human activity that has caused the increase in the earth’s temperature. They think that the increased extra amount of carbon dioxide is trapping more heat energy, thus causing the global temperature to go up. It is believed that the levels of carbon dioxide have increased greatly over the last 100 to 150 years.However, there are some different attitudes towards the causes of this increase in carbon dioxide.On one hand, some scientists find that, over the next 100 years, theamount of warming could be as low as 1 to 1.5 degrees Celsius, but it could be as muchas 5 degrees Celsius. They think that an increase of five degrees would be acatastrophe. It is possible, in their opinions, future warming would cause the sea level torise byseveral meters.On the other hand, some other scientists predict that any warming will be mild with few bad environmental consequences. They are convinced that more carbon dioxide is in fact a positive thing.What is certain is that at present no one knows what the effects of global warming will be.Para 8 developer Para 6 developer Para 7 developer Para 9 Para 10Para 11。
