【題目】In the United States alone,over 100 million cell-phones are thrown away each year.Cell-phones are part of a growing mountain of electronic waste like computers and personal digital assistants.The electronic waste stream is increasing three times taster than traditional garbage as a whole.

Electronic devices contain valuable metals such as gold and silver.A Swiss study reported that while the weight of electronic goods represented by precious metals was relatively small in comparison to total waste,the concentration(含量)of gold and other precious metals was higher in So-called e-waste than in naturally occurring minerals.

Electronic wastes also contain many poisonous metals.Even when the machines are recycled and the harmful metals removed,the recycling process often is carried out in poor countries,in practically uncontrolled ways which allow many poisonous substances to escape into the environment.

Creating products out of raw materials creates much more waste material,up to 100 times more,than the material contained in the finished products.Consider again the cell-phone,and imagine the mines that produced those metals,the factories needed to make the box and packaging(包裝)it came in.Many wastes produced in the producing process are harmful as well.

The U.S Environmental Protection Agency notes that most waste is dangerous in that"the production, distribution,and use of products-as well as management of the resulting waste-all result in greenhouse gas release." Individuals can reduce their contribution by creating less waste at the start-for instance,buying reusable products and recycling.

In many countries the concept of extended producer responsibility is being considered or has been put in place as an incentive(動機)for reducing waste.If producers are required to take back packaging they use to sell their products,would they reduce the packaging in the first place?

Governments' incentive to require producers to take responsibility for the packaging they produce is usually based on money.Why,they ask,should cities or towns be responsible for paying to deal with the bubble wrap(氣泡墊)that encased your television?

From the governments' point of view,a primary goal of laws requiring extended producer responsibility is to transfer both the costs and the physical responsibility of waste management from the government and tax-payers back to the producers.

1By mentioning the Swiss study,the author intends to tell us that .

A. the weight of e-goods is rather small B. natural minerals contain more precious metals

C. E-waste deserves to be made good use of D. the percentage of precious metals is heavy in e-waste

2The responsibility of c-waste treatment should be extended .

A. from producers to governments B. from governments to producers

C. from individuals to distributors D from distributors to governments

3What docs the passage mainly talk about?

A. The increase in e-waste. B. The creation of e-waste.

C. The seriousness of e-waste. D. The management of e-waste.

【答案】

1B

2B

3D

【解析】試題分析:本文是一篇科普說明文。文章主要介紹了電子垃圾的產(chǎn)生、危害以及相關(guān)解決措施。

1B推理判斷題。文章第一段告訴我們,每年有大量廢棄電子產(chǎn)品被隨意丟棄。緊接著第二段首句指出:電子設(shè)備中含有有用的金屬,如金和銀,并用Swiss study佐證這一觀點,因此可以推知電子垃圾值得充分利用。故選B項。

2B細節(jié)理解題。文章第六、七、八三段圍繞生產(chǎn)者責(zé)任延伸展開的,最后一段做了總結(jié), 根據(jù)“a primary goal of laws requiring extended producer responsibility is to transfer both the costs and the physical responsibility of waste management from the government and tax-payers back to the producers ”可知B項正確,是對該句的同義壓縮。故選B項。

3D主旨大意題?v觀全文,文章先描述了廢棄電子產(chǎn)品被隨意丟棄這一現(xiàn)象,接著指出電子垃圾的可以用價值和潛在風(fēng)險,主要是由于對廢棄電子產(chǎn)品的管理不善造成的,最后呼吁政府和生產(chǎn)商對此承擔(dān)一定的責(zé)任。故選D項。
