1、 CLIMATE CHANGE REQUIRES THE WORLDS ATTENTION气候变化需要全世界的关注We have known about climate change for decades. 我们几十年前就知道气候变化了。There is little doubt that Earth is getting warmer and warmer (see the graph). 毫无疑问，地球正变得越来越暖和（见图表） A warming ocean and atmosphere along with melting ice and rising sea levels prov

2、ide evidence of a dramatic change in the global climate.海洋变暖和大气变暖以及冰川融化和海平面上升是全球气候的急剧变化的证据。知识点：1. for +段时间 现在完成时标志2. 比较级+比较级 越来越3. along with 伴随In 2013, a lot of people were shocked by a news photo of a dead polar bear that was found on Norways Arctic island of Svalbard. 2013年，一张在挪威北极地区的斯瓦尔巴群岛上发现了一只

4、 died. 一位研究北极熊多年的专家说，从它尸体的位置看，这只熊似乎是饿死的。Experts claimed that low sea-ice levels caused by climate change meant the bear could not hunt seals as before, so it had to travel greater distances in order to find food. 专家称，由于气候变化造成的海冰水位较低，这只熊无法像以前那样捕猎海豹，所以他为了找到食物不得不去更远的地方。This alarming case showed how the

5、 increase in temperature had an impact on Earths ecology.这一令人震惊的案例表明气温升高对地球生态产生了怎样的影响。知识点：1. be shocked by 被震惊2. according to 根据3. have an impact on 对有影响Then what is causing the increase in the global average surface temperature? 那么是什么正在导致全球表面平均温度的上升呢？ Climate scientists often mention a key climate

6、process called the “greenhouse effect”, which has two common meanings: the “natural” greenhouse effect and the “man-made” greenhouse effect. 气候科学家经常提到一个被称为“温室效应”的关键气候过程，它有两个普遍的含义：“自然”温室效应和“人为”温室效应。The “natural” greenhouse effect refers to the fact that heat from the sun enters the atmosphere and war

7、ms Earths surface as short-wave radiation. “自然”温室效应指的是来自太阳的热量进入大气层，并以短波辐射的形式使地球表面升温。The heat is released back into space at longer wave lengths. 热量以更长的波长释放回太空。 Greenhouse gases in the atmosphere, such as methane and carbon dioxide, trap some of the heat, keeping Earths climate warm and habitable. 大气

8、中的温室气体，如甲烷和二氧化碳，会吸收一些热量，使地球气候保持温暖和适宜居住。Without this process, Earth could not sustain life. 没有这个过程，地球就无法维持生命。However, the “man-made” greenhouse effect has now become a big problem. 然而，“人为”温室效应现在已经成为一个大问题。When people produce huge amounts of extra greenhouse gases by burning fossil fuels, more heat ene

9、rgy is trapped in the atmosphere and causes Earths surface temperature to rise quickly.当人们通过燃烧化石燃料产生大量额外的温室气体时，更多的热量被困在大气中，导致地球表面温度迅速上升。知识点：1. the increase in 在某方面增加2. refer to 指的是There is strong and comprehensive evidence that the rise in temperature has led to an increase in extreme weather and na

10、tural disasters worldwide, not only causing serious damage, but also costing human lives. 有力且全面的证据表明，气温上升已导致世界范围内极端天气和自然灾害的增加，不仅造成严重的破坏，而且还致人丧命。Climate scientists have warned that if we do not take appropriate actions, this warming trend will probably continue and there will be a higher price to pay

13、 emissions.各国政府需要考虑制定政策并采取适当的行动和措施来减少温室气体排放。 We as individuals can also reduce our “carbon footprint” by restricting the amount of carbon dioxide our lifestyles produce. 作为个人，我们也可以通过限制生活方式产生的二氧化碳的量来减少我们的“碳足迹”。It is our responsibility to seize every opportunity to educate everyone about global warmin

14、g, along with its causes and impacts, because this is the most serious issue affecting all of us on this planet. So what will you do to help?我们有责任抓住每一个机会，让每个人了解全球变暖及其原因和影响，因为这是影响我们这个星球上所有人的最严重的问题，那么你会怎么做呢？知识点;1. result in 造成，导致2. result from 由造成3. all over the world 全世界4. consider doing 考虑做5. take measures to do sth 采取措施做某事6. seize an opportunity to do sth 抓住机会做某事高一英语 第 5页 (共4页) 高一英语 第 6页 (共4页)学科网（北京）股份有限公司
