19．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 faster 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．

33．What's the author's purpose to mention the Swiss study？C．
A．the weight of e-goods is rather small
B．natural minerals contain more precious metals

D．the percentage of precious metals is heavy in e-waste
34．The responsibility of e-waste treatment should be extendedD．
A．from producers to governments
B．from government to individuals
C．from individuals to distributors
D．from governments to producers
35．What does the passage mainly talk aboutB
A．how to increase e-waste．
B．how to manage e-waste．
C．what's the result of e-waste．
D．how serious the e-waste is．
分析 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．隨著電子數(shù)碼科技的進步，產(chǎn)生了越來越多的電子垃圾．手機、電腦和電子元器件等被越來越多地扔掉，里面含有像金銀之類的貴金屬，但也含有大量的有毒物質(zhì)，作者詳細(xì)地分析了造成這一問題的原因，并提出了堅決問題的建議和措施
解答 32．C 細(xì)節(jié)理解題． 根據(jù)文章第一段內(nèi)容Cell-phones are part of a growing mountain of electronic waste like computers and personal digital assistants 電話，電腦以及各個電子產(chǎn)品的零部件都屬于電子產(chǎn)品，故選C．
33．C 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"Electronic devices contain valuable metals such as gold and silver．"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，據(jù)此可知作者想要告訴我們，電子垃圾值得被充分運用．故答案選C．
34．D 細(xì)節(jié)理解題．文中六、七、八段圍繞"生產(chǎn)責(zé)任延伸"展開，最后一段做了總結(jié)．根據(jù)最后一段的"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．"可知處理電子垃圾的責(zé)任應(yīng)該從政府延伸到用戶身上．故答案選D．
35．B 主旨大意題．這篇短文主要講述了電子垃圾被隨意丟棄這一現(xiàn)象，文中詳細(xì)分析了造成這一問題的原因，并提出了建議．故答案選B"電子垃圾的管理"．而其余三項都只是概括了文章的部分內(nèi)容，并不能概括全文
點評 本文是社會文化類閱讀理解．做這類題材閱讀理解時要求考生對文章通讀一遍，做題時結(jié)合原文和題目有針對性的找出相關(guān)語句進行仔細(xì)分析，結(jié)合選項選出正確答案．推理判斷題也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確答案，切忌胡亂猜測，一定要做到有理有據(jù)
