3、ay can we breathe fresh air freely and live a happy life.In conclusion,we should advocate and live a low-carbon lifestyle.请保护我们的生活环境 随着经济的快速发展，我们地区的空气污染已经成为当今最严重的问题之一。有时我们不得不戴上面具。为了保护我们的生存环境，我们必须采取必要的措施。首先，步行或骑自行车上学，而不是坐汽车。其次,一些排放废气的工厂应该关闭或迁出城市。此外，我们必须种植越来越多的树。只有这样，我们才能自由呼吸新鲜空气，过上幸福的生活。总之，我们应该提倡低碳生活

4、方式。你校英语报刊人物专栏正在征稿,请你用英语介绍一位你所敬佩的在逆境中成长的人物并投稿。要点如下:1.对该人物的简单介绍;2.敬佩该人物的理由;3.从该人物身上得到的启示。注意:词数80左右。Every time I read Three Days to See,I cannot help being moved by its author Helen Keller.l admire Helen because she was optimistic about life.She became deaf and blind when she was 19 months old.But she

10、f a dramatic change in the global climate.我们了解气候变化已经有几十年了。毫无疑问，地球是在变得越来越暖(见表)。海洋和气候变暖以及冰的融化和海平面的上升为全球气候的剧烈变化提供了证据。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.According to the scientists who found its dead body,all that

11、 remained of the polar bear was skin and bones.An expert who has studied polar bears for many years said that from the position of its dead body,the bear appeared to have starved and died.Experts claimed that low sea-ice levels meant that the bear could not hunt seals as before,so it had to travel g

15、ural greenhouse effect and the man-made greenhouse effect.The natural greenhouse effect refers to the fact The heat is released back into space at longer wave lengths.Greenhouse gases in the atmosphere,such as methane and carbon dioxide,trap some of the heat,keeping Earths climate warm and habitable

16、.Without this process,Earth could not sustain life.However,the man-made greenhouse effect has now become a big problem.When people produce huge amounts of extra greenhouse gases by burning fossil fuels,more heat energy is trapped in the atmosphere and causes Earths surface temperature to rise quickl

17、y.那么，是什么导致全球平均表面温度上升?气候科学家经常提到一个称为“温室效应”的重要气候过程，它有两个普遍的含义：“自然”温室效应和“人造”温室效应。“自然”温室效应是指太阳的热量进入大气层，并以短波辐射的形式使地球表面变暖。热量以更长的波长释放回太空。大气层中的温室气体(如甲烷和二氧化碳)吸收了部分热量，使地球的气候温暖宜居。没有这个过程，地球将无法维持生命。然而，“人造”温室效应现在已成为一个大问题。当人们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层中，从而引起地球表面温度迅速上升。There is strong and comprehensive evidence th

19、ms and heatwaves causing deaths and economic losses.有充分而全面的证据表明，温度升高导致全世界范围内极端天气和自然灾害增加，不仅造成了严重的破坏，而且还造成了人员伤亡。气候科学家警告说，如果我们不采取适当的行动，这种变暖趋势可能会持续下去，并且需要付出更高的代价。事实上，新闻报道经常播出极端暴雨和热浪造成死亡和经济损失。Continued greenhouse gas emissions will result in further warming and long-lasting changes to the global climate.

20、This requires the attention of people all over the world.Governments need to consider making policies and taking appropriate actions and measures to reduce greenhouse gas emissions.We as individuals can also reduce our carbon footprint by restricting the amount of carbon dioxide our lifestyles produ

22、放。我们个人也可以通过限制生活方式产生的二氧化碳量来减少“碳足迹”。抓住每一个机会，对所有人进行全球变暖及其成因和影响的教育，这是我们的责任，因为这是影响我们地球上所有人最严重的问题。那你会怎么做?prehensive6.trendSelf-evaluationSelf-evaluation7.haveanimpacton8.broadcast9.policy10.restrict11.seizetheopportunitytodoI.I.用方框内所给词或短语的正确形式填空（每个用方框内所给词或短语的正确形式填空（每个 词或短语只能用一次）。词或短语只能用一次）。1.He_asonattheu
