Using Garbage as a Fuel

Garbage can be a good fuel to use. The things in garbage do not look 【1】 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 【2】 energy source. Burning garbage 【3】 ( be) not a new idea. Some cities in Europe and the United States 【4】 (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 【5】 ( build). In Paris, France, some power plants burn almost 2 million metric tons of the city’s garbage each year. The amount of energy 【6】 (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 【7】 (easy) , such as food and paper, must be separated from metals, glass, and other materials 【8】 do not. Another problem is that burning garbage can pollute the air. Our fossil fuel supplies are 【9】 (limit) .

Answer 1

【答案】

【1】like

【2】an

【3】is

【4】have been burning

【5】buildings

【6】produced

【7】easily

【8】that/ which

【9】limited

【10】piling

【解析】

试题分析：垃圾能变成实用的好原料。

【1】like 固定词组：look like看起来像---一样，故填like。

【2】an 句意：你可能把垃圾当做一种能源。此处表示泛指，以元音开头的词钱夹an，故填an。

【3】is 动名词短语作主语后面的谓语动词用单数形式，故填 is。

【4】have been burning 句意：在欧洲和美国一些城市多年来一直燃烧垃圾。根据句意可知用“现在完成时态的被动语态”。故填have been burning。

【5】buildings 句意：产出的蒸汽发电或为附近的建筑物供热。此处的名词用复数形式故填buildings。

【6】produced 此处是过去分词作后置定语，故填produced。

【7】easily 此处是副词修饰动词，故填easily。

【8】that/ which 考查定语从句。other materials是先行词，指物，从句缺少引导词，缺少主语，故填that/ which.

【9】limited 句意：我们的矿物燃料是有限的。故填limited。

【10】piling 句意：堆在地球上的垃圾。此处是现在分词短语作后置定语，故填piling。

【名师点拨】

不定冠词a 和an的用法。a用在以元音开头的词前，表示“一”； an用在以辅音开头的词前，表示“一”。比如小题1，university 这个词以辅音开头，所以前面加a，表示一所大学。an important meeting 一个重要的会议；an interesting story 一个有趣的故事；an old man 一位老人；an hour 一小时；an honest boy 一个诚实的男孩；an American lawyer一个美国的律师； a useful tool 一个有用的工具；a European friend一位欧洲的朋友。
