There is less agreement over exactly how nations should go about achieving a more carbon free planet. Thus，the environmental equivalent: cap-and-trade

14、carbon emissions，or place a carbon tax on all users?With cap-and-trade programs，governments limit the level of carbon produced by an industry. Companies that hold their emissions below the cap can sell their remaining allowance on a carbon market，while companies that go beyond their limit must purch

15、ase credits on that market. Carbon taxes are more straight forward: a set tax rate is placed on the consumption of carbon with the idea that raising the price will encourage industries and individuals to consume less. At the moment，cap-and-trade has the upper hand，but doesnt defeat the tax just yet.

16、Supporters of the tax argue that a cap-and-trade system would be too difficult to administerand too easily gamed by industries looking to sidestep emissions caps. Cap-and-trade advocates contradict that like all other flat taxes，a carbon collection would relatively burden lower income families，who s

17、pend a greater percentage of their income on energy than rich households.So which system will have a larger effect on carbon consumption? A 10% carbon tax might reduce the demand for carbon about 5% or less，according to an analysis by the Carbon Tax Center，an environmental advocacy group. That may n

18、ot be enough. Businesses and governments havent figured out how the two competing systems can work together，but in the end，the world may need both.1The passage focuses on _.Aprograms of collecting taxesBsystems of reducing carbon emissionsCreasons for reducing carbon emissions Dcontradictions betwee

19、n the two systems解析：选B。主旨大意题。根据第一段 Everyone agrees that its necessary to reduce carbon emissions around the world.然后下面紧接着介绍了 cap-and-trade 的体制，可知文章的主题是谈论限制对一氧化碳气体的排放的制度。2According to the cap-and-trade program，companies _.Aare forbidden to produce carbon emissionsBare allocated the same amount of car

20、bon consumptionCcan sell their remaining allowance within their limitsDcan sell the extra amount of carbon at a higher price解析：选C。细节题。根据第二段 Companies that hold their emissions below the cap can sell their allowance on a carbon market 可知，把废气排放量控制在规定线以下的工厂可以把剩余的碳气卖出去。3The underlined word “cap” in the

21、second paragraph most likely refers to _.Alimit BcreditClevel Drate解析：选A。词义理解题。根据上句.government limit the level of carbon produced by industry. Companies that hold their emissions below the cap.可知此处的cap 就是指上文所提到的政府对废气排放的限制量。4We can learn from the passage _.Acarbon taxes are difficult to carry outBcap

22、-and-trade plays a greater role at presentCcap-and-trade will be preferable in the futureDcarbon taxes will be preferable in the future解析：选B。推理判断题。根据最后一段So which system will have a larger effect on carbon consumption? A 10% carbon tax might reduce the demand for carbon about 5% or less.可推测出虽然 cap-an

23、d-trade 也不完全是易操作的一个体制，但目前还是占有较重要地位。B(2011年三月济南市联考)How much can environment affect intelligence? In one study，striking increases in IQ occurred in 25 children who were moved from an orphanage(孤儿院) to more stimulating environments. The children，who were all considered mentally retarded and inadaptable

24、，were moved to an institution (慈善机构) where they received personal attention from adults. Later，these supposedly retarded children were adopted by parents who gave them love，a family，and a stimulating home environment. The children gained an average of 29 IQ points. For one child，the increase was an

25、amazing 58 points .A second group of initially less “retarded” children，who stayed in the orphanage，lost an average of 26 IQ points.Other encouraging results can be found in early childhood education programs，which provide stimulating intellectual experiences for disadvantaged children. In one study

26、，children from lowincome families were given enriched environments from early infancy(婴儿期)through preschool. By age 2 their IQ scores were already higher than those in a control group. More important，they were still 5 points higher seven years later. High-quality enrichment programs such as Head Sta

27、rt can prevent children from falling behind in school.A particularly striking environmental effect is the fact that 14 nations have shown average IQ gains of from 5 to 25 points during the last 30 years. These IQ boosts(增加)，averaging 15 points，occurred in far too short a time for genetics(遗传学) to ex

28、plain them. It is more likely that the gains reflect environmental forces，such as improved education，nutrition，and living in a technologically complex society.【解题导语】本文是一篇调查报告，研究表明环境影响孩子的智力。5Whats the main idea of this passage?ARetarded children cannot improve their IQs.BOrphanages are full of mental

29、ly retarded children.CEnvironmental factors influence a childs IQ.DEarly childhood education programs are important.解析：选C。主旨大意题。文章一开始作者提出“环境对智力有多大影响？”作者写了孤儿院儿童因环境改变而智力提高的研究结果。第二段作者谈到了早期教育对孩子智力提高有影响。第三段讲述了30年来14个国家儿童受环境影响平均智力提高，从遗传学角度很难解释。所以文章讲述了环境影响智力。6What does the underlined word “retarded” in the

30、 first paragraph most probably mean?AUndeveloped. BRejected.CIgnored. DDeserted.解析：选A。词义推断题。孤儿院的儿童缺乏良好的家庭环境，所以智力发育迟缓。7The author is in favor of _ according to the passage.Aputting retarded children into institutionsBproviding early childhood education programsCkeeping children in orphanagesDkeeping

31、retarded children with others like themselves解析：选B。作者态度推断题。作者既然认为环境影响智力，那么就应该是赞成对儿童实施早期教育。8What can we conclude from the passage?AAttention from parents has little effect on a childs IQ.BHead Start programs are a waste of money.CIncreases in IQ have happened in the US more rapidly than elsewhere.DGenetics are less important than environment in gaining ones IQ.解析：选D。细节推断题。运用排除法，A、D两项与文章内容相反，C项文章没有提到。结合最后一段“.occurred in far too short a time for genetics to explain them.”可知答案为D。高考资源网版权所有，侵权必究！
