人教版英语选修六第四单元课文翻译（Translated edition English Elective six fourth unit text translation）Unit fourth global warmingGlobal warming is one. What's the effect?During twentieth Century, the earth's temperature rose by about 1 degrees fahrenheit. This value is probably not important to you and me, but compared to other natural changes, this is a rapid growth. So how does this increase in temperature happen? What's the effect? Sophie Armstrong, the organization for caring for the earth, is exploring these issues.There is no doubt that the earth is warming (see Table 1), and that the warming of the earth is caused by human activities, not an irregular natural phenomenon.All scientists agree with the idea that burning fossil fuels (such as coal, gas and oil) in order to produce energy raises the temperature of the earth. Some of the byproducts of this warming process are called greenhouse gases, the most important of which is carbon dioxide. Dr. Janice Foster explained:"There is a natural phenomenon scientists call the 'greenhouse effect'. This phenomenon occurs in the atmosphere, a small amount of gas (such as carbon dioxide, a, Anhui, water vapor, etc.) to absorb the heat of the sun, so that when the earth warming. Without this greenhouse effect, the earth would be about 33 degrees cooler than it is today. So we need these gases. The problem arises when we add a great deal of extra carbondioxide to the atmosphere. This means that more heat is trapped in the atmosphere, causing global temperatures to rise. "We know that carbon dioxide levels have increased dramatically over the past 100-150 years. A scientist named Charles Keeling once made accurate statistics on the amount of carbon dioxide in the atmosphere during the 1957-1997 years. He found that the amount of carbon dioxide in the atmosphere rose from 315/1000 000 to 370/1000 0000 over the years (see table two, slightly)All scientists accepted the data. They also agree that the increase in carbon dioxide is due to more and more burning of fossil fuels. "Then how high will the temperature rise?" Dr. Forster said, "in the next 100 years, the amount of global warming may be as low as 1-1.5 degrees Celsius, but it could be as high as 5 degrees Celsius."However, scientists are quite different in their attitudes towards warming. On the one hand, Dr Forster argues that the trend of warming 5 degrees could be a catastrophe. "We can't make accurate predictions about the future climate, but the weather may be bad at that time," she said. Other scientists agree with her view that global warming could cause sea levels to rise by several meters: others predicted severe storms, floods, droughts, famines, epidemics, and extinction of species. On the other hand, there are some people, like scientist George Hanbury, who oppose the above view. They don't think we need to worry about the high levels of carbon dioxide in the air. They predicted that the warming situation would not be too serious and the environmental impact would not be too bad. Hanbury actually said so:"The increase in carbon dioxide is actually a good thing. It makes plants grow faster, produce more crops and promote growth, all of which can improve human life.". "Greenhouse gases continue to collect in the atmosphere.". Even if we begin to reduce carbon dioxide and other greenhouse gases, the climate will continue to get warmer in the next few decades or centuries. No one knows what impact global warming will have. Does that mean we don't have to take any measures? Or, do not take any risks too great?Using languageWhat can we do about global warming?Dear Earth Care Organization: I am doing a research project on global warming on behalf of our school. Sometimes I feel that individuals can't do much about such a huge environmental problem. However, I still believe that people should support the improvement of daily energy consumption.Because I'm not sure where I should begin to begin my research.I hope to get your advice.Thanks, Ouyang GuangDear Ouyang Guang:There are a lot of people who take on your obligations, and they don't believe they have the power to influence the environment. The idea is incorrect. Every man sticks his wood, and his flameis high. We don't have to put up with pollution.The growth of greenhouse gases and carbon dioxide in the air is indeed derived from many of our daily activities. Here are some suggestions for reducing the carbon dioxide content in the air. These suggestions should contribute to your research.1. indoors, we use a lot of energy. You can leave it on when you use the appliance. Turn it off if you don't use it. Don't be careless about it. So, if you don't use the lights, the TV, the computer, turn them off. If you feel cold, put on more clothes rather than turn the heat on2. motor vehicles use a lot of energy. So, if possible, walk or ride a bike.3. recycle cans, bottles, plastic bags, and newspapers. It takes a lot of energy to do this with new materials, so buy the materials that are made of recycled materials whenever possible.4. advise your parents to buy energy saving products, including cars and small items such as refrigerators and microwave ovens.5. grow trees in your garden or campus. They can absorb carbon dioxide from the air and make you feel fresh when you watch them.6. finally, and most importantly, be an educator. Talk to your family and friends about global warming and tell them what you've learned.Remember, your contribution is valuable.。
