1、Intelligent Machines1. Medical scientists are already putting computer chips (芯片) directly into the brain to help people who have Parkinson\'s disease, but in what other ways might computer technology be able to help us? Ray Kurzweil is author of the successful book The Age of Intelligent Machines and is one of the world\'s best computer research scientists. He is researching the possibilities.2. Kurzweil gets computers to recognize voices. An example of this is Ramona; the virtual (虚拟的) hostess of Kurzweil\'s homepage, who is programmed to understand what you say. Visitors to the site can have their conversations with her, and Ramona also dances and sings.3. Kurzweil uses this technology to help people with physical disabilities. One of his ideas is a "seeing machine". This will be "like a friend that could describe what is going on in the visible world", he explains. Blind people will use a visual sensor (探测器) which will probably be built into a pair of sunglasses. This sensor will describe to the person everything it sees.4. Another idea, which is likely to help deaf people, is the "listening machine". This invention will recognize millions of words and understand any speaker. The listening machine will also be able to trans late into other languages, so even people without hearing problems are likely to be interested in using it.5. But it is not just about helping people with disabilities. Looking further into the future, Kurzweil sees a time when we will be able to download our entire consciousness onto a computer. This technology probably won\'t be ready for at least 50 years, but when it arrives, it means our minds will be able to live forever.Paragraph 4 ____【单选题】

A.A new pair of eyes

B.Computers that can communicate

C.Everlasting consciousness on a computer

D.Time to break off a friendship

E.An author and researcher

F.A new pair of ears

正确答案:F

答案解析:本题难度不大，第四段有明显的主旨句：Another idea, which is likely to help deaf people, is the“listening machine”，主要讲其如何帮助聋哑人听见东西。F项A new pair of ears，“一对新的耳朵”，可以概括本段内容，答案是F。

2、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.Some serious diseases is connected with deficiency of ____【单选题】

A.industrially polluted soils

B.rock and soil chemistry

C.naturally polluted soils

D.the pathways of metals into the food chain

E.the element of iodine

F.the persistence of heavy metals

正确答案:E

答案解析:第1段最后一句“A lack of iodine in the human diet leads to some serious diseases”是选择E的依据。

3、A Strong Greenhouse Gas1 Methane is a colorless, odorless gas; it is also a potent greenhouse gas, and once released into the atmospheres, it absorbs beat radiating from Earth\'s surface. That\'s why methane is a major contributor to the planet\'s increasing temperature rise or global warming. Molecule for molecule, methane\'s heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide, the most abundant greenhouse gas.2 With 13 billion cows belching almost constantly around the world (100 million in the U. S. alone), it\'s no surprise that menace released by livestock is one of the chief sources of the gas. Other prime methane sources: petroleum, drilling, coal mining, solid-waste landfills and wetlands.3 Greenhouse gases like methane and carbon dioxide make up only a small part of Earth\'s atmosphere, which is 78 percent nitrogen and nearly 21 percent oxygen. And without greenhouse gases to trap the sun\'s heat and warm the planet, life as we know it couldn\'t exist. But in the last200 years, human activity that requires burning oil, natural gas, and coal for energy has magnified the greenhouse effect.4 Atmospheric concentrations of methane have more than doubled in the last two centuries. Blame for this often focuses on big industries and gas-guzzling vehicles. But agriculture plays a major role, too. In the past 40 years alone, the global cattle population has doubled.5 Cows munch mostly grasses and hay yet they grow big and hefty. Why? Because of the rumen. The rumen holds 160 liters of food and billions of microbes. These microscopic bacteria and protozoa break down cellulose and Fiber into digestible nutrients. A cow couldn\'t live without its microbes. As the microbes digest cellulose, trey release methane. The process occurs in all animals with a rumen (cows, sheep, and goats, for example), and it makes them very gassy. It\'s part of their normal digestion process. When they drew their cud, they regurgitate some food to rechew it, and all this gas comes out. The average cow expels 600 liters of methane a day.That\'s why we say livestock gas is also a major factor of causing the global warming.Generally people heap criticism on fox the planet\'s temperature rise ____ .【单选题】

A.one of tire major contributors

B.the ever-increasing atmospheric concentration of greenhouse gases

C.big and hefty cows

D.livestock\'s normal digestion process

E.how to cut down the cattle population

F.big industries and gas-guzzling vehicles

正确答案:F

答案解析:第4段第2句直接谈到这个问题，人们常常将不断加剧的温室效应归罪于大工业和汽车，而cattle释放甲烷的因素被忽略了。

4、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 3 ____【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:E

答案解析:第3段的第1句话： 同年Ford以提出一天最低5美元的工资制度而震惊世界，这是他至此作出的最大的贡献。这是个主题句。

5、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.Most people will not be able to use the new technology because ____【单选题】

A.Running 10 miles every day

B.It does not exist

C.They hope to find out what has made them live so long

D.walking

E.enjoy life

F.It will be very expensive

正确答案:F

答案解析:题干问的是：大多数人不会使用这项新技术的原因是什么？第2段末尾已经阐述的很清楚是费用昂贵。
