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 for a number of elements such as iodine, zinc and selenium. For example, 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 or losing some of their chemical constituents. The crops we eat selectively remove from the soil the elements that they require for growth. 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 or metal-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 6 ______【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:C

答案解析:答案的依据是本段的第2句：Future environmental investigations of naturally polluted soils should concentrate on the potential pathways of metals into the food chain and human body.

2、Longer Lives Are Happier Lives1 In recent years, scientists have been studying ways to change the body\'s chemistry to reduce the signs and effects of aging.2 0ne group of researchers in Britain has performed experiments on a kind of worm. They have managed to increase the worm\'s normal life span of 20 days by up to 400%. They hope that they will be able to use this research to help humans live longer. However, this is a long way in the future. Another disadvantage is that when (or if) the new technology is successfully developed, it will probably be very expensive. The chance to live longer will only be available to a very few, very rich people.3 Another group of scientists is studying people who have reached a very old age. They believe that this may show what has kept these people healthy and alive for so long. So, if we look at people who have lived into very old age, what do they have in common? Usually they have led a physically active life. This does not mean going to a gym or running ten miles every day. Simple, enjoyable activities like walking seem to be more likely to keep you healthy. Very old people also eat a good, varied diet. Simple foods like vegetable, rice, pasta and fish are the best.4 However, there may be one thing even more important than physical factors like diet and exercise. Research shows that personality, and the way a person thinks, play an important part in how long they will live. People who live into very old age always seem to enjoy life. They have a sense of humor and get satisfaction from simple things. They do not constantly think about the past, but are interested in the present and the future. They do not let life get boring, but have interests and hobbies which keep their minds active and they are open to new ideas. One Japanese man who lived to be 120 commented that the secret of his long life was "not worrying". To express it simply, people who are happy and positive about life are more likely to live longer.5 So, eat well, exercise well, and enjoy life, and you will have a good chance of living to a healthy, happy old age.Paragraph 5 ____【单选题】

A.How to live happy old age

B.Disadvantages of the project

C.The study of old people

D.Personality and other mental factors are more important

E.Worms live longer than humans

F.Live simple lives

正确答案:A

答案解析:这是一个固定句式，祈使句加上and加将来时等于if条件句。只要能做到吃好，锻炼好，享受生活，就会有健康的幸福的晚年。

3、Ford(1)Ford\'s great strength was the manufacturing process not invention. Long before he started a car company, he was a worker, known for picking up pieces of metal and wire and turning them into machines. He started putting cars together in 1891, although it was by no means the first popular automobile, the Model T showed the world just how creative Ford was at combining technology and market.(2)The company\'s assembly line alone. threw America\'s Industrial Revolution into overdrive(高速运转）. Instead of having workers put together the entire car, Ford\'s friends, who were great toolmakers from Scotland, organized teams that added parts to each Model T as it moved down a line. By the time Ford\' s Highland Park plant was humming (嗡嗡作响) along in 1914, the world\'s first automatic conveyor belt could turn out a car every 93 minutes.（3）The same year Henry Ford shocked the world with the $5 a day minimum Wage scheme, the greatest contribution he had ever made. The average Wage in the auto industry then was $2. 34 for a9-hour shift. Ford not only doubled that he also took an hour off the workday. In those years it was unthinkable that a man could be paid that much for doing something that didn\'t involve an awful lot of training or education. The Wall Street Journal called the plan "an economic crime" and critics everywhere laughed at Ford.(4)But as the wage increased later to daily $10, it proved a critical component of Ford\'s dream to make the automobile accessible to all The critics were too stupid to understand that because Ford had lowered his costs per car, the higher wages didn\'t matter, except for making it possible for more people to buy cars.paragraph 4 ____【单选题】

A.Ford\'s Followers

B.The Assembly Line

C.Ford\'s Great Dream

D.The Establishment of the ompany

E.Ford\'s Biggest Contribution

F.Ford\'s Great Talent

正确答案:C

答案解析:第4段的第1句：然而，随着工资后来升到一天10美元，Ford梦想中的关键部分，即大家都买得起汽车，是可以实现的。因此，C是正确的答案。

4、Ceasing to Wear TiesIt\'s useless. It\'s dirty. It spreads disease. That\'s why the British Medical Association in the UK recently called for hospital doctors to stop wearing ties.That leads to another question. Why does anyone wear a tie? Ties serve no purpose. They do not cover any part of your body and keep you warm. They always seem to get covered in food stains. Perhaps that is the purpose of the tie. It lets everyone know what you just ate.Ties have an odd history. Soldiers from Croatia, in Eastern Europe, served as mercenaries (雇佣军) in various conflicts in the 17th century. They were identified by brightly colored pieces of silk worn around the neck. Known as cravats(围巾), these became a popular fashion item in France and eventually evolved into the tie.It\'s an interesting story, but it doesn\'t tell us why men want to put useless pieces of cloth or silk around their necks. The answer seems to be about identification(身份证明 ). In the 19th-century Britain, ties were used by universities, military regiments (团), sports clubs, schools and gentleman\'s clubs. Each tie was in a particular set of colors which identified the wearer as a member of that organization. Wearing ties was also the mark of Britain\'s most powerful classes. That made the tie itself a symbol of power and respect. And that led it to be adopted by a much larger class-the business class.You cannot wear a tie if you work with machinery, so wearing a tie became a sign that you were a man who used his brain to make a living, rather than his hands. It showed you were serious. It showed you were a professional. It meant that everyone who wanted a job in business had to wear one. It was just impossible to take seriously a man who did not wear a piece of colored silk around his neck. This is how millions of people came to wear ties across the world.Is there a future for ties? The signs are not promising. Many political leaders, including British Prime Minister Tony Blair, now go without ties.Paragraph 6 ________.【单选题】

A.Origin of the tie

B.British ties

C.Uselessness of the tie

D.Old-fashioned ties

E.Role of the tie

F.Signs of a tieless era

正确答案:F

答案解析:第六段的主题句是第二句：The signs are not promising.这里the signs后边省略了of the future of ties。该句说明领带的前景不是很好。比如在后一句中讲到英国首相布莱尔等政治家经常在公共场合不再戴领带，这进一步说明了以后人们可能不再打领带。F选项Signs of a tieless era与其表达相符，故F为正确答案。
