分析 从1850年起,地球表面的气温已经上升了0.6°C,科学家们预测到本世纪末气温可能更高.是谁让温度上升了呢?嗯,好像是我们自己!引起全球变暖自然因素只占了一小部分,而几乎所有的科学家现在都同意人类活动是影响的主因.在过去的150年,我们已经排放了大量的温室气体,特别是二氧化碳.这些气体可以使地球表面温度升高,因此二氧化碳越多地球表面的温度就越高.全球变暖可以改变气候引发更多强烈飓风、洪水和干旱.
当我们燃烧物品时就会增加二氧化碳的排放,特别是化石矿物燃料,化石矿物燃料是数百万年前由植物和动物的残骸形成的能源.煤炭,石油,天然气都是化石矿物燃料.美国以及其他国家的人早在一个世纪以前就开始开采大量的化石矿物燃料.化石矿物燃料的燃烧量每年在全世界还在不断地增加.我们烧的越多,就会制造更多的二氧化碳.我们能帮什么忙吗?现在低碳生活在全世界得到广泛认可.低碳意味着减少二氧化碳排放,节约以及重复利用能源是关键.事实上,每天做些最简单的事情就可以使我们的生活低碳.
解答 66.Global warming may change the weather in ways that lead to more severe storm,floods and droughts.细节理解题.根据第二段Global warming may change the weather in ways that lead to more severe(严重的) storms,floods and droughts.全球变暖可以改变气候引发更多强烈飓风、洪水和干旱.故答案是
Global warming may change the weather in ways that lead to more severe storm,floods and droughts.
67.Fossil fuels are energy sources formed from the remains of plants and animals that lived millions of years ago.Coal,oil,and natural gas are all fossil fuels.细节理解题.根据第三段Fossil fuels are energy sources formed from the remains of plants and animals that lived millions of years ago.Coal,oil,and natural gas are all fossil fuels化石矿物燃料是数百万年前由植物和动物的残骸形成的能源.煤炭,石油,天然气都是化石矿物燃料,故答案是
Fossil fuels are energy sources formed from the remains of plants and animals that lived millions of years ago.Coal,oil,and natural gas are all fossil fuels.
68.在过去的150年间,我们向空气中排放了大量这类气体,特别是二氧化碳.英译汉题.Over the past 150years表示在过去的150年间,give out排放,large amounts of大量的,especially特别是,尤其是,故答案是在过去的150年间,我们向空气中排放了大量这类气体,特别是二氧化碳.
69.the more carbon dioxide will be produced.根据上下文补全短文.结合第三段We add carbon dioxide to the air when we burn things,especially fossil fuels(矿物燃料).当我们燃烧物品时就会增加二氧化碳的排放,特别是化石矿物燃料,故我们烧的越多,就会制造更多的二氧化碳,结合The more we burn,联想到用句型the+比较级,the+比较级,其中前面的句子是状语从句,后面的句子是主句.若主句的谓语动词用一般将来时,从句的谓语动词要用一般现在时表示将来.故这里主句用一般将来时,carbon dioxide 不可数名词,故用much的比较级more,carbon dioxide 是动词produce的承受者,构成被动关系,故用一般将来时的被动语态will+be+过去分词,故答案是the more carbon dioxide will be produced.
70.We'd better go to school by bike or on foot.开放性题目.结合文意,低碳就是减少二氧化碳的生成,我们知道汽车能产生二氧化碳,故我们最好不要坐汽车,而是骑自行车或者走路上学,had better do sth做好做某事,故答案是We'd better go to school by bike or on foot.
