1、Geology ａｎｄ　Heap(1)The importance of particular metals in the human diet has been realized within the past few decades, ａｎｄ　the idea that geology might be related to health has been recognized fｏｒa number of elements such as iodine, zinc ａｎｄ　selenium. Fｏｒexample, soils with low iodine contents produce crops, ａｎｄ　animals deficient in iodine. A lack of iodine in the human diet leads to some serious diseases.(2)The ultimate source of metals within the human body is rocks, which weather into soil, gaining ｏｒlosing some of their chemical constituents. The crops we eat selectively remove from the soil the elements that they require fｏｒgrowth. The water we drink contains trace elements leached from rock ａｎｄ　soil. Thus the geology ａｎｄ　geochemistry of the environment have effects on the chemistry ａｎｄ　health of plants, animals ａｎｄ　people.(3)So far there is no data to suggest that people living on metal-rich soils experience a potential health hazard. The levels of metals within naturally contaminated soils are generally not high enough to cause serious health problems. Living on metal-rich soils does not represent a health risk unless large quantities of soil are digested ｏｒmetal-rich dust is inhaled. However, small children are particularly exposed to metal-rich topsoil in playgrounds ａｎｄ　gardens. They are also the most likely ones to eat potentially dangerous metal-rich soil.(4)Heavy metals are persistent: they do not break down to other chemicals in the environment. Industrially polluted sites usually undergo intensive clean-up ａｎｄ　rehabilitation because heavy metals are a health concern once they enter the food chain. Some trace metals are alleged to cause cancer ａｎｄ　are also known to cause poisoning(5)In contrast, naturally contaminated soils have not been subject too risk assessment studies ａｎｄ　rehabilitation measures, despite the fact that they frequently possess metal concentrations well above those of such polluted by humans ａｎｄ　above environmental quality criteria.(6)There is a vital need to understａｎｄ　the potential risks ａｎｄ　long-term health effects of living on naturally contaminated soils. Future environmental investigations of naturally polluted soils should concentrate on the potential pathways of metals into the food chain ａｎｄ　human body. Geologists should be part of such studies as they can provide the essential background information on rock ａｎｄ　soil chemistry as well as the chemical forms of heavy metal pollution.Paragraph 4 ______【单选题】

A.No Evidence to Indicate Bad of Naturally Contaminated Soil

B.Potential Hazards of Human Contaminated Soils

C.Research an Channels of Heavy Metals Getting into Human Food Chain

D.Geology ａｎｄ　Health Problems

E.Rocks----the Ultimate Source of Soil Pollution

F.Long-term Health Effects on Children

正确答案:B

答案解析:第4段说，受到工业污染的土壤含有重金属，而重金属很稳定，不容易降解。因此某些微量重金属能使人致癌和中毒。

2、Human Space ExplorationWhile scientists are searching the cause of the Columbia disaster, NASA is moving ahead with plans to develop a new craft that would replace shuttles(航天飞机) on space station missions by2012 ａｎｄ　respond quickly to space station emergencies.The space agency released the first ｓｅｔof mission needs ａｎｄ　requirements several days ago fｏｒme orbital space plane (轨道航天飞机), which would be designed to transport a crew of four to ａｎｄ　from the International Space Station.Although it includes few specifics, the plan states the orbiter(轨道航天飞机) will be safer cheaper ａｎｄ　require less preparation time than the shuttle. It would be able to transport four crew members by 2012 though it would be available fｏｒrescue missions by 2010. NASA says the craft should be able to transport injured ｏｒill space station crew members to "definitive(决定性的) medical care" within 24 hours.The release of the requirements showed NASA remains focused on the long-term priorities of space exploration, even as questions exist concerning the loss of Columbia ａｎｄ　its seven member crew on February l, 2003.Expels at Marshall Space Flight Center in Huntsville, Alabama, have been working fｏｒyears on a successｏｒto the shuttle. The project, known as the Space Launch Initiative (倡议), was divided last year into two parts----one focusing on a future launch vehicle, the other on a space station orbiter. The orbiter is expected to be ready sooner.The program\'s managers say NASA officials have told them not to ａｌｔｅｒSpace Launch Initiative in light of the Columbia disaster.U. S. President George W. Bush asked Congress fｏｒabout US$1 billion fｏｒSpace Launch Initiative in 2004, funds that would be almost equally split between the Orbital Space Plane ａｎｄ　Next Generation Launch Technology.According to the passage, the l billion funds, if granted, would .【单选题】

A.be used to rebuild the International Space Station

B.be awarded to the scientists working at NASA

C.be shared by the two projects under the Space Launch Initiative

D.be spent on the investigation of the Columbia disaster

正确答案:C

答案解析:此题问的是10亿美元的款项被批准后用来干什么？选项A的意思是重建国际空间站，选项B的意思是颁发给在NASA工作的科学家，这两个选项都与原文意思不符。最后一段说，若10亿美元的款项获得国会的批准，这笔款项基本上平分给the Orbital Space Plane和Next Generation Launch Technology这两个研究项目，故C为正确答案。

3、Greene spent a brief time at Cambridge.【单选题】

A.hard

B.short

C.good

D.long

正确答案:B

答案解析:格林在剑桥作了简短停留。本题难度不大，干扰项干扰不大，是送分题，可以确认brief和short都是“简短的”的意思，答案是B。

4、DyslexiaAs many as 20% of all children in the United States suffer from some form of the learning disｏｒｃｅｒcalled dyslexia.Experts on dyslexia say that the problem is not disease. They say that persons with dyslexia use information in a different way. One of the world\'s great thinkers ａｎｄ　scientists, Albert Einstein was dyslexic. Einstein said that he never thought in words the way that most people do. He said that he thought in pictures instead. The American inventｏｒThomas Edison was also dyslexic. Dyslexia first was recognized in Europe ａｎｄ　the United States more than 80 year ago. Many years passed before doctors discovered that persons with the disｏｒｃｅｒwere not mentally slow ｏｒdisabled. The doctors found that the brains of persons with dyslexia are different. In most people, the left side of the brain, the part that controls language is larger than the right side. In persons with dyslexia, the right’ side of the brain is bigger. Doctors are not sure what causes this difference. However, research has shown that dyslexia is more common in males that in females, ａｎｄ　it is found more often in persons who are left-handed. No one knows the cause of dyslexia, but some scientists believe that it may result from chemical changes in a baby\'s body long before it is born. They are trying to find ways to teach persons with dyslexia. Dyslexic persons think differently ａｎｄ　need special kinds of teaching help. After they have solved their problems with language, they often show themselves to be especially intelligent ｏｒcreative.The first cases of dyslexia in Europe were discovered less than a century ago.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:题目中的关键词是专有名词Europe，我们很快在第2段第5行找到答案所在句。通过对比题目和答案所在句，我们发现从recognize—discover，more than 80 years ago—less than a century ago都属于同义改写，但唯一有差别的是文中提到的两个地方： Europe和 the United States在80多年前发现了读写困难症病例. 但题目中仅仅提到了Europe。对于这个问题，我们可以进行如下推理：设A= Europe，B=the United States，实际上这道题就变为一道推理题：如果A+B正确，那么A是否正确？实际上很简单：A+B成立（正确）的充分必要条件是AUB正确，即A正确或者B正确。经过这样的推理，我们知道该题的答案应为A。

5、Gun Rights in the USImmediately after the shooting at Virginia Tech University, Americans gathered to mourn (致哀) the dead. The president ａｎｄ　the state governer both hurried there to share the grief. But the majority of Americans still cling to their right to ____ weapons.Strictly speaking, the US is not the only country here gun violence has destroyed lives, families ａｎｄ　communities in everyday circumstance. But the US is one of the few countries that seem unwilling ａｎｄ　politically incapable of doing anything serious to stop it.In countries like Britain ａｎｄ　Canada, the government adopted strict gun control soon after serious gun violence incidents. US leaders, however, are held hostage by the gun lobby (院外活动集团) ａｎｄ　the electoral (选举) system.The powerful National Rifle Association, the majｏｒsupporter of gun rights in the US, is too strong fｏｒany party to take on. Most Republicans oppose gun control anyway. Over the years, the Democrats have found that they can either campaign fｏｒgun control ｏｒwin power, not both, they prefer power.According to the US Bureau of Justice Statistics, firearm (火器) incidents accounted fｏｒnine percent of the 4.7 million violent crimes in 2005. So although opinion polls show most Americans want stricter gun laws, many people don\'t want to give up their arms they keep to protect themselves.Dave Hancock, a Virginia gun lover, is one example. In an interview he said, "If one professｏｒin the Virginia incident had been carrying a legal weapon, they might have been able to stop all this. "In his opinion, the massacre (大屠杀) is an argument fｏｒmore people to carry weapons, not fewer.Americans\' clinging to the right to bear arms is not just a fear of crime, but a mistrust of government, commented UK\'s Guardian newspaper.One Virginia resident, who had a permit to carry a concealed (隐藏的) firearm, told the Guardian that it was every American\'s responsibility to have a gun."Each person," he said, "should not rely solely on the government fｏｒprotection."【单选题】

A.own

B.make

C.destroy

D.trade

正确答案:A

答案解析:本题有一定难度，干扰项有一定的干扰性，需要认真阅读文章，判断好句意。本题可以先看选项，得到信息提示。本文一开始谈到了由枪支引起的惨剧，接着后面出现了but，表示转折，说明多数美国人还是倾向拥有枪支，所以此处要选“拥有”的意思，答案是A。
