12、们受得了这么热吗？在过去的几十年里，科学家一致认为，人类正在造成地球气候的变化这是一种原来被认为是超出我们控制能力的现象。他们声称，在过去的 50 年里，工厂和车辆排入地球大气层中的气体加速了全球变暖的进程，影响了我们的气候。展望未来，科学家们认为全球变暖可能是 21 世纪面临的最严重的环境问题之一。但是，确切地说，什么是全球变暖？为什么把它视为一种危险？它如何与我们的生活相关呢？助读讲解 in the last/past few decades/years/months/days 常与现在完成时连用。现在分词短语 facing the 21st century 作后置定语，修饰 the bi
13、ggest environmental problems。Global warming refers to an average increase in the Earths temperature that,in turn,leads to climate change.Scientists found that the temperature of the Earth is controlled by greenhouse gases such as carbon dioxide which trap heat from the sun in the Earths atmosphere.W
14、ithout these naturally occurring gases,the suns rays would bounce(反弹)back into space leaving the Earth cold and impossible to live on.When the presence of these gases in the atmosphere increases,however,more heat is trapped and the Earths temperature rises.全球变暖指的是地球温度平均增长，继而导致气候变化。科学家们发现地球的气温受温室气体如二
15、氧化碳的控制，这些气体能将来自太阳的热量留在地球的大气层里。如果没有这些自然产生的气体，太阳光线将会被反射回太空中，使得地球处于寒冷之中而不适合生命的存在。然而，当大气层中的这些气体的浓度不断增加时，更多的热量被留在地球，造成地球气温上升。助读讲解 此处是 that 引导的定语从句，修饰 an average increase in the Earths temperature。which 引导的定语从句，修饰先行词 greenhouse gases。此句是 without 引出的含蓄虚拟句，the suns rays would bounce.是与现在事实相反的虚拟语气，其中 leaving

18、ta,it seems that the link between human activities and rising global temperatures is not merely a coincidence.在过去的 100 年里，全球的平均温度增加了 1 华氏度，许多专家坚持认为，在很大程度上，人类的活动是导致全球变暖的重要原因。随着工业、农业规模的不断扩大，成片成片的森林被砍伐，交通运输日益频繁，燃料消耗不断增长，每年有接近 6 吨的二氧化碳被释放到供地球上 60 亿人中的每一个人呼吸的空气当中。在过去的 250 年里，大气中的二氧化碳含量已经增加了 30%以上，而其中的一半是
19、在1960 年以后增加的。考虑到这个数据，人类活动与正在上升的全球温度之间的关联似乎不仅仅是一个巧合。助读讲解 given prep.考虑到，鉴于。A temperature increase of 1F may not sound like a lot,but if we continue to produce carbon dioxide and other gases in such huge quantities,we are condemning life on Earth and should expect severe consequences.Recent reports wa

22、。Governments all over the world have a responsibility to reduce the amount of carbon dioxide which their countries are producing.If less carbon dioxide goes into the atmosphere,global warming will slow down.This is no easy task,however,and some governments,for example,the USAs federal government,exp

25、 changes made by everyone worldwide，they wont be such small changes.They could be the changes that save our future.After all,theres no substitute for our Earth.Its all weve got to live on.世界上的每一个政府都有责任降低自己国家二氧化碳的排放量。如果少向大气中释放二氧化碳，全球变暖就会慢下来。然而，这是一项非常艰巨的任务，一些政府，例如美国的联邦政府，对于全球变暖是否真的是由人类活动引起的仍持保留意见。许多人认
26、为他们只是不愿意牺牲自己从工业中赚到的钱来拯救地球。但是为什么要等待政府来采取行动呢？专家主张每个人都发挥作用。他们建议做一些小小的改变。比如搭乘公共交通工具，循环利用(资源)，使用节水沐浴龙头，购买节能灯泡。甚至是一些非常简单的事情，如使用再生纸或离开房间时关上灯，都会有用。如果把全世界每个人做的小小改变累加起来，它们就不是小改变了，而是拯救我们未来的改变。毕竟，地球没有替代品，它是我们必须赖以生存的全部。助读讲解 whether global warming is.是介词 about 的宾语，介词之后只能用 whether 不能用 if。suggest doing sth.建议做某事。ma
27、de by everyone worldwide 是过去分词短语作后置定语，修饰changes。weve got to live on 是定语从句，修饰先行词 all，在从句中作宾语，关系代词省略。第一步 速读了解文章主题和段落大意速读 P6 教材课文，匹配段落大意1Para.1 AWhat is global warming?2Para.2 BThe effects of global warming.3Para.3 CThe cause of global warming.4Para.4 DThe ways to solve the problems.5Para.5 EDraw the r
