CLIMATE CHANGE REQUIRES THE
WORLD'S ATTENTION
We have known about climate change for decades①. There is little doubt that Earth is getting warmer and warmer (see the graph②)．[1] A warming ocean and atmosphere along with③ melting④ ice and rising sea levels provide evidence⑤ of a dramatic⑥ change in the global climate.
[1]本句是复合句。“There is little doubt...”意为“毫无疑问……”， that引导同位语从句，解释说明doubt的具体内容。
In 2013, a lot of people were shocked by⑦ a news photo of a dead polar bear that was found on Norway's Arctic island of Svalbard [2]. According to⑧ the scientists who found its dead body, all that remained⑨ 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 starved⑩ and died. Experts claimed that low sea-ice levels caused by climate change [3] meant the bear could not hunt seals as before ， so it had to travel greater distances in order to find food. This alarming case showed how the increase in temperature had an impact on Earth's ecology .
[2]此处是that引导的定语从句，修饰先行词polar bear。
[3]此处是过去分词短语作后置定语，修饰名词levels。
Then what is causing the increase in the global average surface temperature Climate scientists often mention a key climate process called the “greenhouse effect”， which has two common meanings: the “natural” greenhouse effect and the “man-made” greenhouse effect.[4] The “natural” greenhouse effect refers to the fact that heat from the sun enters the atmosphere and warms Earth's surface as short-wave radiation [5]. The heat is released back into space at longer wave lengths. Greenhouse gases in the atmosphere, such as methane and carbon21 dioxide22, trap23 some of the heat, keeping Earth's climate warm and habitable24[6]. Without this process, Earth could not sustain25 life. However, the “man-made” greenhouse effect has now become a big problem. When people produce huge amounts of26 extra greenhouse gases by burning fossil27fuels28 [7], more heat energy is trapped in the atmosphere and causes Earth's surface temperature to rise quickly [8].
[4]本句是复合句。called the “greenhouse effect”是过去分词短语作后置定语，修饰名词process; “which has...effect”是定语从句，修饰先行词the “greenhouse effect”。
[5]此处是that引导的同位语从句，解释说明fact的具体内容。
[6]此处是现在分词短语作结果状语， warm and habitable是形容词作宾语补足语。
[7]此处是动词-ing短语作介词by的宾语。
[8]此处是动词不定式短语作宾语补足语。
There is strong and comprehensive29 evidence that the rise in temperature has led to an increase in extreme weather and natural disasters worldwide30, not only causing serious damage, but also costing human lives.[9] Climate scientists have warned that if we do not take appropriate actions, this warming trend31 will probably continue and there will be a higher price to pay[10]. In fact, news reports are frequently32broadcast33 about extreme rainstorms and heatwaves causing deaths and economic losses34[11].
[9]本句是复合句。“There is...evidence”是主句；“that the rise...lives”是同位语从句，解释说明evidence的具体内容。“not only causing...”和“but also costing...”是两个并列的现在分词短语作结果状语。
[10]此处是动词不定式作定语，修饰名词price。
[11]此处是现在分词短语作后置定语，修饰名词短语rainstorms and heatwaves。
Continued35 greenhouse gas emissions36 will result in37 further warming and long-lasting38 changes to the global climate. This requires the attention of people all over the world. Governments need to consider making policies39 and taking appropriate actions and measures to reduce greenhouse gas emissions.[12] We as individuals40 can also reduce our “carbon footprint41” by restricting42 the amount of carbon dioxide our lifestyles produce [13]. It is our responsibility43 to seize44 every opportunity to educate everyone about global warming, along with its causes and impacts, because this is the most serious issue45 affecting all of us on this planet. So what will you do to help [14]
[12]本句是简单句。“to consider...and measures”是动词不定式短语作动词need的宾语； making policies和“taking...measures”是两个并列的动名词短语作动词consider的宾语；“to reduce...emissions”是动词不定式短语作目的状语。
[13]此处是定语从句，省略了关系代词that/which，修饰先行词carbon dioxide。
[14]此处是动词不定式作目的状语。
[课文翻译]
气候变化需要全世界的关注
我们几十年前就知道气候变化了。毫无疑问，地球正在变得越来越温暖(见图表)。海洋和大气的变暖以及冰川的融化和海平面的上升，为全球气候的急剧变化提供了证据。
2013年，一张新闻照片让很多人感到震惊。照片中是北极圈内挪威斯瓦尔巴群岛上发现的一具北极熊尸体。据发现北极熊尸体的科学家说，这只北极熊只剩下了“皮和骨头”。一名研究北极熊多年的专家说，从尸体的位置来看，这只熊似乎是饿死的。专家称，气候变化造成海冰水位较低，意味着这只熊无法像以前那样捕猎海豹。所以为了寻找食物，它不得不长途跋涉。这一令人震惊的案例表明，气温升高对地球生态产生了影响。
那么是什么导致了全球平均表面温度上升呢？气候科学家经常提到一个被称为“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“人为”温室效应。“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变暖。热量以更长的波长释放回太空。大气中的温室气体，如甲烷和二氧化碳，会捕获一些热量，使地球气候保持温暖且适宜居住。如果没有这个过程，地球就无法维持生命。然而，“人为”温室效应现在已经成为一个大问题。当人类由于燃烧化石燃料产生大量额外的温室气体时，更多的热能被困在大气中，导致地表温度迅速上升。
有充分而全面的证据表明，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，这种变暖的趋势可能会继续下去，并将(使我们)付出更高的代价。事实上，新闻经常报道造成死亡和经济损失的极端暴雨和热浪。
持续的温室气体排放将导致全球气候进一步变暖和长期变化。这需要全世界人民的关注。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。作为个人，我们也可以通过限制生活方式所产生的二氧化碳排放量来减少我们的“碳足迹”。我们有责任抓住每一个机会，对每个人进行全球变暖及其原因和影响的教育，因为这是影响我们这个星球上所有人的最严重的问题。那么你会做什么来助力呢？

CLIMATE CHANGE REQUIRES THE
WORLD'S ATTENTION
We have known about climate change for decades①. There is little doubt that Earth is getting warmer and warmer (see the graph②)．[1] A warming ocean and atmosphere along with③ melting④ ice and rising sea levels provide evidence⑤ of a dramatic⑥ change in the global climate.
[1]本句是复合句。“There is little doubt...”意为“毫无疑问……”， that引导同位语从句，解释说明doubt的具体内容。
In 2013, a lot of people were shocked by⑦ a news photo of a dead polar bear that was found on Norway's Arctic island of Svalbard [2]. According to⑧ the scientists who found its dead body, all that remained⑨ 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 starved⑩ and died. Experts claimed that low sea-ice levels caused by climate change [3] meant the bear could not hunt seals as before ， so it had to travel greater distances in order to find food. This alarming case showed how the increase in temperature had an impact on Earth's ecology .
[2]此处是that引导的定语从句，修饰先行词polar bear。
[3]此处是过去分词短语作后置定语，修饰名词levels。
Then what is causing the increase in the global average surface temperature Climate scientists often mention a key climate process called the “greenhouse effect”， which has two common meanings: the “natural” greenhouse effect and the “man-made” greenhouse effect.[4] The “natural” greenhouse effect refers to the fact that heat from the sun enters the atmosphere and warms Earth's surface as short-wave radiation [5]. The heat is released back into space at longer wave lengths. Greenhouse gases in the atmosphere, such as methane and carbon21 dioxide22, trap23 some of the heat, keeping Earth's climate warm and habitable24[6]. Without this process, Earth could not sustain25 life. However, the “man-made” greenhouse effect has now become a big problem. When people produce huge amounts of26 extra greenhouse gases by burning fossil27 fuels28 [7], more heat energy is trapped in the atmosphere and causes Earth's surface temperature to rise quickly [8].
[4]本句是复合句。called the “greenhouse effect”是过去分词短语作后置定语，修饰名词process; “which has...effect”是定语从句，修饰先行词the “greenhouse effect”。
[5]此处是that引导的同位语从句，解释说明fact的具体内容。
[6]此处是现在分词短语作结果状语， warm and habitable是形容词作宾语补足语。
[7]此处是动词-ing短语作介词by的宾语。
[8]此处是动词不定式短语作宾语补足语。
There is strong and comprehensive29 evidence that the rise in temperature has led to an increase in extreme weather and natural disasters worldwide30, not only causing serious damage, but also costing human lives.[9] Climate scientists have warned that if we do not take appropriate actions, this warming trend31 will probably continue and there will be a higher price to pay [10]. In fact, news reports are frequently32 broadcast33 about extreme rainstorms and heatwaves causing deaths and economic losses34[11].
[9]本句是复合句。“There is...evidence”是主句；“that the rise...lives”是同位语从句，解释说明evidence的具体内容。“not only causing...”和“but also costing...”是两个并列的现在分词短语作结果状语。
[10]此处是动词不定式作定语，修饰名词price。
[11]此处是现在分词短语作后置定语，修饰名词短语rainstorms and heatwaves。
Continued35 greenhouse gas emissions36 will result in37 further warming and long-lasting38 changes to the global climate. This requires the attention of people all over the world. Governments need to consider making policies39 and taking appropriate actions and measures to reduce greenhouse gas emissions.[12] We as individuals40 can also reduce our “carbon footprint41” by restricting42 the amount of carbon dioxide our lifestyles produce [13]. It is our responsibility43 to seize44 every opportunity to educate everyone about global warming, along with its causes and impacts, because this is the most serious issue45 affecting all of us on this planet. So what will you do to help [14]
[12]本句是简单句。“to consider...and measures”是动词不定式短语作动词need的宾语； making policies和“taking...measures”是两个并列的动名词短语作动词consider的宾语；“to reduce...emissions”是动词不定式短语作目的状语。
[13]此处是定语从句，省略了关系代词that/which，修饰先行词carbon dioxide。
[14]此处是动词不定式作目的状语。

气候变化需要全世界的关注
我们几十年前就知道气候变化了。毫无疑问，地球正在变得越来越温暖(见图表)。海洋和大气的变暖以及冰川的融化和海平面的上升，为全球气候的急剧变化提供了证据。
2013年，一张新闻照片让很多人感到震惊。照片中是北极圈内挪威斯瓦尔巴群岛上发现的一具北极熊尸体。据发现北极熊尸体的科学家说，这只北极熊只剩下了“皮和骨头”。一名研究北极熊多年的专家说，从尸体的位置来看，这只熊似乎是饿死的。专家称，气候变化造成海冰水位较低，意味着这只熊无法像以前那样捕猎海豹。所以为了寻找食物，它不得不长途跋涉。这一令人震惊的案例表明，气温升高对地球生态产生了影响。
那么是什么导致了全球平均表面温度上升呢？气候科学家经常提到一个被称为“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“人为”温室效应。“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变暖。热量以更长的波长释放回太空。大气中的温室气体，如甲烷和二氧化碳，会捕获一些热量，使地球气候保持温暖且适宜居住。如果没有这个过程，地球就无法维持生命。然而，“人为”温室效应现在已经成为一个大问题。当人类由于燃烧化石燃料产生大量额外的温室气体时，更多的热能被困在大气中，导致地表温度迅速上升。
有充分而全面的证据表明，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，这种变暖的趋势可能会继续下去，并将(使我们)付出更高的代价。事实上，新闻经常报道造成死亡和经济损失的极端暴雨和热浪。
持续的温室气体排放将导致全球气候进一步变暖和长期变化。这需要全世界人民的关注。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。作为个人，我们也可以通过限制生活方式所产生的二氧化碳排放量来减少我们的“碳足迹”。我们有责任抓住每一个机会，对每个人进行全球变暖及其原因和影响的教育，因为这是影响我们这个星球上所有人的最严重的问题。那么你会做什么来助力呢？
