题目内容
8.New studies show how food and its production affect the globe and its climate.The process of making a hamburger,for example,requires lots of energy.A cow has to be fed and raised on farmland.And cow waste is a major source of methane(沼气)-(48)anespecially powerful greenhouse gas.The cow has to be killed.The meat has to be processed and shipped,(49)whichtakes fuel.Most of the cow won't even be used for meat people eat.By the time a hamburger finally lands o a dinner plate,(50)ithas made bad effect on the environment.We can reduce the production of global warming gases by eating less beef.Other kinds of meat like pork and chicken do(51)lessharm to the environment---at least(52)interms of the amount of greenhouse gases released.(53)However,all kinds of meat are harder on the planet than vegetables.(54)Sochanging our diet to less meat and more vegetables,as it turns (55)out,may do the world some good.
分析 本文作者主要向读者介绍了一些新的研究发现;即通过介绍汉堡的制作过程,具体讲述了食品及其生产过程是如何影响全球以及它的气候变化的;文中还讲到了我们应对全球气候变化的策略,即可以通过将我们的饮食习惯改变为少吃肉类尤其是少吃牛肉,多吃蔬菜来减少使全球变暖的气体的产生.
解答 答案:
48.an 考查不定冠词 此处用来修饰单数名词gas,表示泛指"一种特别强大的温室气体",故此处应使用不定冠词;由于especially首字母的发音为元音/i/,故用an
49.which 考查关系代词 本句为非限定性的定语从句;意为:牛肉必须得加工和运输,这需要燃料;此处指代的是前面的一整句话,故用关系代词which
50.it 考查上下文句意理解以及人称代词 本句的意思是:当一个汉堡包最终摆上餐桌上的时候,它便对环境造成了不良的影响;结合上文可知,此处代指的应是:汉堡的制作过程,故用it
51.less 考查上下文句意理解以及形容词的比较级 本句的意思是:其他种类的肉,如猪肉和鸡肉对环境的危害则较小;此处表示两者(牛肉与其他种类的肉,如猪肉和鸡肉)之间的比较,故用形容词的比较级less
52.in 考查固定短语的用法 固定短语in terms of 意为:在…方面,依据,按照;此处指的是:至少在温室气体排放量方面;故用in
53.However 考查上下文句意理解以及副词 承接上文可知,此处表达的是转折的意思;即尽管猪肉和鸡肉对环境的危害要小于牛肉,但是凡事肉类都比蔬菜的危害大; 并根据空缺处之后的逗号可知,此处应填表示转折的副词However
54.So 考查上下文句意理解以及副词 结合上下文可知,此处表示针对上文陈述的事实所得出的结论:因此将我们的饮食改变为少吃肉类和多吃蔬菜,可能对全世界都会有好处;故用So
55.out 考查固定的表达方式 as it turns out在本句中为插入语,意为:事实证明;故用out
