高二人教新课标选修6 unit 4 课文翻译

Reading 1THE EARTH IS BECOMING WARMER — BUT DOES IT MATTER During the 20th century the temperature of the earth rose about one degree Fahrenheit. That probably does not seem much to you or me, but it is a rapid increase when compared to other natural changes. So how has this come about and does it matter Earth Care's Sophie Armstrong explores these questions.There is no doubt that the earth is becoming warmer (see Graph 1) and that it is human activity that has caused this global warming rather than a random but natural phenomenon.All scientists subscribe to the view that the increase in the earth's temperature is due to the burning of fossil fuels like coal, natural gas and oil to produce energy. Some byproducts of this process are called "greenhouse" gases, the most important one of which is carbon dioxide. Dr Janice Foster explains: "There is a natural phenomenon that scientists call the 'greenhouse effect'. This is when small amounts of gases in the atmosphere, like carbon dioxide, methane and water vapour, trap heat from the sun and therefore warm the earth. Without the "greenhouse effect', the earth would be about thirty-three degrees Celsius cooler than it is. So, we need those gases. The problem begins when we add huge quantities of extra carbon dioxide into the atmosphere. It means that more heat energy tends to be trapped in the atmosphere causing the global temperature to go up." We know that the levels of carbon dioxide have increased greatly over the last 100 to 150 years. It was a scientist called Charles Keeling, who made accurate measurements of the amount of carbon dioxide in the atmosphere from 1957 to 1997. He found that between these years the carbon dioxide in the atmosphere went up from around 315 parts to around 370 parts per million (see Graph 2).All scientists accept this data. They also agree that it is the burning of more and more fossil fuels that has resulted in this increase in carbon dioxide. So how high will the temperature increase go Dr Janice Foster says that over the next 100 years the amount of warming could be as low as 1 to 1,5 degrees Celsius, but it could be as high as 5 degrees.However, the attitude of scientists towards this rise is completely different. On the one hand, Dr Foster thinks that the trend which increases the temperature by 5 degrees would be a catastrophe. She says, "We can't predict the climate well enough to know what to expect, but it could be very serious." Others who agree with her think there may be a rise of several metres in the sea level, or predict severe storms, floods, droughts, famines, the spread of diseases and the disappearance of species. On the other hand, there are those, like George Hambley, who are opposed to this view, believe that we should not worry about high levels of carbon dioxide in the air. They predict that any warming will be mild with few bad environmentalconsequences. In fact, Hambley states, "More carbon dioxide is actually a positive thing. It will make plants grow quicker; crops will produce more; it will encourage a greater range of animals —all of which will make life for human beings better." Greenhouse gases continue to build up in the atmosphere. Even if we start reducing the amount of carbon dioxide and other greenhouse gases, the climate is going to keep on warming for decades or centuries. No one knows the effects of global warming. Does that mean we should do nothing Or, are the risks too great第四单元全球在变暖全球在变暖一一这会带来什么影响吗在20世纪期间,地球温度大约升了华氏1度。

Unit4 Global warming (选修6)-2023届高三英语第一轮课时复习

Part C．故事复述
请结合上述问题答案，用自己的话复述课文。
提示词：greenhouse gases，carbon dioxide，effect，catastrophe
答案： Greenhouse gases are byproducts of burning fossil fuels. Carbon dioxide，the most important gas of the greenhouse gases，is a gas produced when we burn fossil fuels. Human beings are burning more and more fossil fuels every day，which produces more and more carbon dioxide. When too much carbon dioxide is added into the atmosphere，more heat is trapped， causing the global temperature to go up. So，it is human activities that have caused global warming. No one knows for sure the effect of global warming. Some think it would be a catastrophe while others think it is a good thing.
