Reading 1THE EARTH IS BECOMING WARMER —BUT DOES IT MA TTER?www.2abc8.coDuring 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."www.2abc8.coWe 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 environmental consequences. 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 willmake life for human beings better."www.2abc8.coGreenhouse 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www.2abc8.co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。
人教版选修6英语unit4-unit5课文翻译
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。
在另一方面，还有一些人，像科学家乔治·汉布利，他认为我们不必担心空气中会有高含量的二氧化碳。

Despite being used by 1.34 billion people each year，traveling on the Tube in London can actually be quite lonely.One citizen，however，is trying to change this.“You get on the Tube and it’s completely silent and it’s weird，”says Jonathan Dunne，who has started a worldwide dialogue after giving out badges(徽章) with the words “Tube chat？” last month，encouraging passengers in London to get talking to one another.“I handed out 500 badges during rush hour in a city of 8 million，expecting most of them to be thrown away，but after about 24 hours it completely snowballed，”he says.Dunne and his “Tube chat”campaign have since been reported by media across the world，seeing TV interviews in Sweden, Brazil and the U．K.，as well as countless website，newspaper and magazine appearances.Although Dunne says he’s received mostly positive feedback，not everyone agrees with his idea.Londoner Brian Wilson responded with a campaign of his own，handing out 500 badges with the words “Don’t even think about it”on them. Michael Robinson，24，a student from London，agrees.“Being on the Tube is the only peace and quiet some people get on their journeys to and from work.It doesn’t need to be spoiled by people coming up and chatting to you，”he says.“People assume that I just walk up and talk to strangers, which I don’t，but it’s been a great way to meet people you would never have normally spoken to，”Dunne says.So if you ever end up using public transport in the West, why not say hello to the person next to you？Just make sure to check for a badge first.【解题导语】每年乘坐伦敦地铁的乘客众多，可是人们仍然感到孤独；为此Jonathan Dunne发起了一个旨在鼓励乘客相互交谈的运动，此举引起了世界媒体的关注。
