global warming rather than a random but natural phenomenon.毫无疑问，地球是在变暖（见表一，略）， 而地球变暖正是人类活动导致而成的，并非是一种无规律 的自然现象。

the atmosphere causing the global temperature to _g_o__u_p____.

• We know that the levels of carbon dioxide have increased greatly over the last 100 to 150 years. 我们知道，在过去 100~150年期间，二氧化碳的含量急剧增加了。 It was a scientist called Charles Keeling, who made accurate measurements of the amount of carbon dioxide in the atmosphere from 1957 to 1997. 有一位名叫查尔斯·基林的 科学家曾经把1957~1997年期间大气层中二氧化碳的含量 作了精确的统计。 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).他发现， 在这些年里，大气层中的二氧化碳含量从315/1000 000上 升到370/1000 000。（见表二，略）

• 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.所有的科学家赞 同这种观点：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。Some byproducts of this process are called "greenhouse" gases, the most important one of which is carbon dioxide.这个升温的 过程的一些副产品就叫做“温室”气体，其中作用重要的 就是二氧化碳。
a random but natural 修饰phenomenon， 译为 “随意的自然的现象”，but起一个 语气转折的作用，可不译出。

atmosphere, like carbon dioxide, methane and water vapour, trap heat from the sun and therefore warm the earth.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，因而使地球变暖的时候。

• Without the 'greenhouse effect', the earth would be about thirty-three degrees Celsius cooler than it is.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。So, we need those gases. The problem begins when we add huge quantities of extra carbon dioxide into the atmosphere.因此，我们需要这些气体。当我们在大气层中 增加了大量额外的二氧化碳时，问题就来了。It means that more heat energy tends to be trapped in the atmosphere causing the global temperature to go up."这意味着更多的热 量被困在大气层中，从而引起全球温度上升。”
汉布利实际上是这样说二氧化碳含量的增加实际上是件好事它使植物成长更快庄稼产量更高还会促进动物的生长所有这些都能改善人类的生活

dioxide C. does great harm to human beings D. makes life for human beings better
• All scientists accept this data. 所有科学家都接受这个数据。 They also agree that it is the burning of more and more fossil fuels that has resulted in this increase in carbon dioxide. 他们 还赞同下述观点，正是由于越来越多燃烧化石燃料导致了 二氧化碳的增加。 So how high will the temperature increase go? 那么气温会升到多高？ Dr Janice Foster says that over the next 100 years the amount of warming could be
