题目内容
8.Using Garbage as a FuelGarbage can be a good fuel to use.The things in garbage do not look (53)like coal,petroleum,or natural gas,but they are chemically similar to these fossil fuels.As we use up our fossil fuel supplies,we might be able to use garbage as (54)an energy source.Burning garbage(55)is( be) not a new idea.Some cities in Europe and the United States (56)have been burning (burn) garbage for years.The heat that is produced by burning garbage is used to boil water.The steam that is produced is used to make electricity or to heat nearby (57)buildings( build).In Paris,France,some power plants burn almost 2million metric tons of the city's garbage each year.The amount of energy (58)produced(produce) is about the same as would be produced by burning almost a half million barrels of oil!
But there are problems in using garbage as a fuel.Garbage that burns(59)easily(easy),such as food and paper,must be separated from metals,glass,and other materials(60)that/which do not.Another problem is that burning garbage can pollute the air.Our fossil fuel supplies are (61)limited (limit).Burning garbage might be one kind of energy source that we can use to help meet our energy needs.This method could also reduce the amount of garbage(62)piling (pile) up on the earth.
分析 本文主要介绍了在欧洲和美国的一些城市以及法国的巴黎是如何将垃圾作为燃料来使用的以及使用垃圾作燃料所存在的两大问题(一是:像食品和纸这些容易燃烧的垃圾,必须要与金属、玻璃和其他不易燃烧的物质分开;二是:燃烧垃圾会污染空气).
解答 答案:
53.like 考查固定短语"look like"意为:看起来像…;故用like.
54.an 考查不定冠词 此处用来修饰名词 source,表示泛指一种能源资源;由于形容词energy 首字母的发音为元音/e/;故用an
55.is 考查时态及主谓一致 根据上下文都使用了一般现在时,可知本文描述的是现在对垃圾的利用情况,所以本句也应使用了一般现在时;由于本句的主语Burning garbage为动名词短语,所以谓语动词应使用第三人称单数形式;故用is
56.have been burning 考查句意理解以及时态 本句的意思是:欧洲和美国的一些城市多年来一直在燃烧垃圾;根据句中的时间状语 for years,可知此处应使用现在完成时,结合句意可知,此处表达的是多年来一直在进行的动作,所以应使用现在完成进行时;由于该句主语的中心词为Some cities,故用have been burning
57.buildings 考查名词的单复数 此处用在形容词nearby之后,指的是:附近的一些大楼;故用复数名词buildings
58.produced 考查过去分词 此处在句中作后置定语,修饰前面的名词energy;由于动词produce与该名词构成了被动关系,故用过去分词produced
59.easily 考查副词 此处在句中修饰动词burns,故用副词easily
60.that/which 考查关系代词 本句为定语从句,由于先行词other materials(指物)在从句中作主语;故用that/which
61.limited 考查形容词 此处在句中作表语,说明主语Our fossil fuel supplies 的情况,故用形容词;limiting"限制的";limited"有限的";本句的意思的是:我们的矿物燃料的供应量是有限的;故用limited
62.piling 考查现在分词 此处在句中作后置定语,修饰前面的名词garbage;由于动词pile与该名词构成了主谓关系,故用现在分词piling
点评 语法填空主要考查了各种语法知识在短文中的具体运用.做本题时,需要在正确理解短文的前提下,逐句分析句意以及所考查到的语法现象;因此在平时的学习中,应熟练掌握各种语法知识,其中包括词法,句法,各种时态语态以及虚拟语气等.
