8、ve finished5can be compared with.阅读理解AIn the United States alone, over 100 million cellphones are thrown away each year. Cellphones 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 tra

9、ditional 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

10、was higher in socalled ewaste 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

11、 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 cellphone, and imagine the mines that produced those metals, the factories neede

12、d to make the box and packaging (包装) it came in. Many wastes produced in the producing process are harmful as well.The US. Environmental Protection Agency notes that most waste is dangerous in that“the production, distribution, and use of productsas well as management of the resulting wasteall resul

13、t in greenhouse gas release.” Individuals can reduce their contribution by creating less waste at the startfor 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 (动机) for redu

14、cing 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

15、 towns be responsible for paying to deal with the bubble wrap (气泡垫) 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

16、 and taxpayers back to the producers.1By mentioning the Swiss study, the author intends to tell us that _Athe weight of egoods is rather smallBewaste deserves to be made good use ofCnatural minerals contain more precious metalsDthe percentage of precious metals is heavy in ewaste2The responsibility

17、of ewaste treatment should be extended _Afrom producers to governmentBfrom government to producersCfrom individuals to distributorsDfrom distributors to government3What does the passage mainly talk about?AThe increase in ewaste.BThe creation of ewaste.CThe seriousness of ewaste.DThe management of ew

18、aste.答案与解析1B推理判断题。根据the Swiss study定位到第二段，根据段落大意“Electronic devices contain valuable metals.the concentration (含量) of gold and other precious metals was higher in socalled ewaste than in naturally occurring minerals.”电子垃圾包含大量的有价金属，而且含量甚至比矿物质中的含量高，言外之意，我们应该好好利用这些电子垃圾，故选项B。2B细节理解题。根据最后一段中的“a primary g

19、oal of laws requiring extended producer responsibility is to transfer both the costs and the physical responsibility of waste management from the government and taxpayers back to the producers.”可知responsibility of waste management from the government and taxpayers back to the producers.责任从政府和纳税人回到生产

20、者，即增强生产者的责任感，重点是回归生产者，故选择B。3D主旨大意题。纵观全文，首先提出电子垃圾急剧增长的现象，进而提出电子垃圾的价值与危害，最后从个人、生产商与政府角度阐述解决方案，故全文从不同的角度讲述如何管理电子垃圾，故选择D。BPeople typically wash their hands seven times a day in the United States, but they do it at a far higher temperature than is necessary to kill germs, a new study says. The energy was

21、te is equivalent to the fuel use of a small country.Amanda R. Carrico, a research assistant professor at the Vanderbilt Institute for Energy and Environment in Tennessee, told National Geographic that hand washing is often “a case where people act in ways that they think are in their best interest,

22、but they in fact have inaccurate beliefs or outdated perceptions.”Carrico said, “Its certainly true that heat kills bacteria, but if you were going to use hot water to kill them it would have to be a way too hot for you to tolerate.”Carrico said that after a review of the scientific literature, her

23、team found “no evidence that using hot water that a person could stand would have any benefit in killing bacteria.” Even water as cold as 40F (4.4C) appeared to reduce bacteria as well as hotter water, if hands were scrubbed, rinsed(冲洗)and dried properly.Using hot water to wash hands is therefore un

24、necessary, as well as wasteful, Carrico said, particularly when it comes to the environment. According to her research, people use warm or hot water 64 percent of the time when they wash their hands. Using that number, Carricos team calculated a significant impact on the planet.“Although the choice

25、of water temperature during a single hand wash may appear unimportant, when multiplied by the nearly 800 billion hand washes performed by Americans each year, this practice results in more than 6 million metric tons of CO2 equivalent emissions annually，” she said.The researchers published their resu

26、lts in the July 2013 issue of International Journal of Consumer Studies. They recommended washing with water that is at a “comfortable” temperature, which they noted may be warmer in cold months and cooler in hot ones.4Whats the meaning of what Carrico told National Geographic in the second paragrap

27、h?APeople are more concerned about their health and begin to wash their hands.BIts important for people to wash their hands to keep healthy.CGenerally, peoples hand washing behaviors and perceptions are not correct.DPeople like washing their hands very much.5The figures in the sixth paragraph are us

28、ed to show that _.Ausing hot water to wash hands has a bad influence on our planetBair pollution has become more and more seriousCusing hot water to wash hands is a waste of energyDpeople should pay more attention to the environment around us6This passage is organized in the pattern of _Afact and op

29、inionBcause and effectCdefinition and classificationDtime and events7What can we learn from the passage?AIts necessary and useful for people to wash their hands frequently every day.BWe can wash our hands with water that is at a “comfortable” temperature.CUsing cold water to wash hands is necessary

30、and much healthier.DHot water cant kill germs.答案与解析本文是一篇研究报告。热水洗手是不是能杀死更多的细菌？研究证明并非如此，而且还浪费了资源。4C细节理解题。根据文章第二段中的 “but they in fact have inaccurate beliefs or outdated perceptions”的转折可知，一般来讲，人们洗手的观念和行为都是不太正确的，故选C。5A推理判断题。根据文章第五段最后一句 “Using that number, Carricos team calculated a significant impact on

31、 the planet”的过渡可知，本句承上启下，第六段引用的那些数字就是为了证明用热水洗手对地球带来的消极影响，故选A。6A写作意图题。通过对文章的整体理解，尤其是第六段可知，本文主要是通过列举事实，同时表达作者自己的观点的方式进行行文的，故选A。7B推理判断题。根据文章最后一段最后一句“They recommended washing with water that is at a comfortable temperature, which they noted may be warmer in cold months and cooler in hot ones.”可知，我们洗手用舒适温度的水即可，不必太热，也不必太凉，故选B。
