1、New Product Will Save LivesDrinking water that looks clean may still contain bugs, which can cause illness. A small company called Genera Technologies has produced a testing method in three stages, which shows whether water is safe. The new test shows if water needs chemicals added to it, to destroy anything harmful. It was invented by scientist Dr. Adrian Patton, who started Genera five years ago. He and his employees have developed the test together with a British water company.Andy Headland, Genera\'s marketing director, recently presented the test at a conference in the USA and forecast good American sales for it. Genera has already sold 11 0fits tests at $42,500 a time in the UK and has a further four on order. It expects to sell another 25 tests before the end of March. The company says it is the only test in the UK to be approved by the government.Genera was formed five years ago and until October last year had only five employees; it now employs 14. Mr. Headland believes that the company should make around $19 million by the end of the year in the UK alone.The new product has been a commercial Success in the USA.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:原文的意思是预计该产品在美国会卖得很好，也就是说还没在美国上市呢。本题干的意思与原文不符，故选B。

2、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.Paragraph 5 ____【单选题】

A.Life of Macroscopic Bacteria in Livestock\'s Rumen

B.Ways to Reduce Methane\'s Heat-trapping Power

C.Agriculture Also Contributes to Increased Concentrations of Methane in the Atmosphere

D.Why Livestock Releases Methane

E.Methane as a Strong Greenhouse Gas

F.Livestock as a Prime Factor of the Greenhouse Effect

正确答案:D

答案解析:本段从科学的角度分析反刍动物为什么会释放出甲烷。

3、A Carrot a Day Keeps Cancer AwayAmong all the malignancies, lung cancer is the biggest killer: more than 100,000 Americans a year die of the disease. Giving up smoking is one of obvious way to reduce the risk, but another answer may lie in the kitchen. According to a new report, even heavy smokers may be protected from developing lung cancer by a simple dietary measure: a daily portion of carrots, spinach or any other vegetable or fruit containing a form of vitamin A called carotene.The finding, published in the British medical journal The Lancet, is part of a long-range investigation of diet and disease. Since 1957 a team of American researchers has monitored the dietary habits and medical histories of 2,000 middle-aged men employed by the Western Electric Co. in Chicago. Led by Dr. Richard Shelelle of Chicago\'s Rush-Presbyterian, St. Luke\'s Medical Center, the researchers recently began to sort out the links between the subjects\' dietary patterns and cancer. Other studies of animals and humans have suggested that vitamin A offers some protection against lung cancer. The correlation seemed logical, since vitamin A is essential for the growth of the epithelial (上皮的) tissue that lines the airways of the lungs.Vegetables: But the earlier research did not distinguish between two different forms of the vitamin. "Preformed" vitamin A, known as retinol, is found mainly in liver and dairy products like milk, cheese, butter and eggs. But vitamin A is also made in the body from carotene, which is abundant in a variety of vegetables and fruits, including carrots, spinach, squash, tomatoes, sweet potatoes and apples.In the Western Electric study, Shekelle and his colleagues found little correlation between the incidence of lung cancer and the consumption of foods containing preformed vitamin A, but when they examined the data on carotene intake, they discovered a significant relationship. Among the488 men who had the lowest level of carotene consumption, there were fourteen cases of lung cancer, in a group of the same size that ate the most carotene, only two cases developed. The apparent protective effect of carotene held up even for longtime smokers but to a lesser degree.Further studies will be necessary before the link between lung cancer and carotene can be firmly established. In the meantime, researchers warn against taking large numbers of vitamin A pills, because the tablets contain a form of the chemical that can be extremely toxic in high doses. Instead, they advise a well-balance diet that includes foods rich in carotene. For a smoker, a half-cup of carrots every day might possibly make the difference between life and death.Where is carotene present?【单选题】

A.tomatoes

B.carrots

C.squash

D.all of the above

正确答案:D

答案解析:根据第3段，“维生素A在体内的产生源于胡萝卜素，胡萝卜素在蔬菜、水果中大量存在，包括胡萝卜、菠菜、西葫芦、西红柿和苹果”。因此答案是D。

4、Making Yourself a Good RecordIf you are an American and you think you might need to borrow money someday, the best thing to do is to start early.That\'s because just as many employers want to hire only people with experience, banks and other creditors are usually reluctant to lend to those without a proven track record of paying back, on time, the money they have borrowed.But if you need experience just to get a start, how do you get that start in the first place?With a little help from your parents usually, while you are still financially dependent on them. It is easy to get a credit card or student loan when you are in college, because banks figure your parents will bail you out if you fail to pay.So just as students take on internships to build up their resumes, one s university time can be a good time to work on another important personal record: the credit reportCredit reports are a summary of one\'s personal credit history, gathered by a credit reporting agency, or CRA.Banks, and companies including hospitals, landlords and insurance companies-regularly report to the three main CRAs in the US on how their customers are doing at paying back the money they owe.Anyone with a "legitimate business need" has the right to order individuals\' reports from the CRAs. Potential creditors usually compile the information in the reports into a credit "score", ranking the level of creditworthiness. Lack of experience in borrowing in addition to a bad record of doing so, can result in a low score.Even if you are not considering taking out a loan for such a large purchase as a home or car, your credit report can be important to getting through life. Landlords often ask for the reports to judge whether a person can be trusted to pay the rent. Credit checks are necessary for getting a credit card, even for purchasing a mobile phone calling plan.People can obtain a copy of their own credit report, usually at a cost of around US$ 8-9. Some consumer organizations recommend doing this once a year to allow one to catch any mistakes that have slipped into the records or, even worse, to find out whether any fraud has taken place. Though the system is controlled by laws meant to protect people\'s privacy, it isn\'t fool-proof. Sometimes people take out bad loads in others\' names, ruining their records.In a society addicted ______credit, that can be a disaster.【单选题】

A.on

B.to

C.by

D.with

正确答案:B

答案解析:此题考查固定搭配(be)addicted to...（沉溺于……）。

5、In the process, the light energy converts to heat energy.【单选题】

6、LanguageWhen one looks back upon the fifteen hundred years that are the life span of the English language, he should be able to notice a number of significant truths. The history of language is a history of constant change-at times a slow, almost imperceptible change, at other times a violent collision between two languages. Language a living growing organism, it has never been static. Another significant truth that emerges from such a study is that language at all times has been the possession not of one class or group but of many. At one extreme it has been the property of the common, ignorant folk, who have used it in the daily business of their living, much as they have used their animals or the kitchen pots and pans. At the other extreme it has been the treasure of those who have respected it as an instrument and a sign of civilization, and who have struggled by writing it down to give it some permanence, order, dignity, and if possible, a little beauty.As we consider our changing language, we should note here two developments that are of special and immediate importance to us. One is that since the time of the Anglo-Saxons there has been an almost complete reversal of the different relationship of words in a sentence. Anglo-Saxon(old English) was a language of many inflections. Modern English has few inflections. We must now depend largely on word order and function words to convey the meanings that the older language did by means of changes in the forms of words. Function words, you should understand, are words such as prepositions, conjunctions, and a few others that are used primarily to show relationships among other words. A few inflections, however, have survived. And when some word inflections come into conflict with word order,. there may be trouble for the users of the language, as we shall see later when we turn our attention to such maters as WHO or WHOM and ME or l. The second fact we must consider is that as language itself changes, our attitudes toward language forms change also. The eighteenth century, for example, produced from various sources a tendency to fix the language into patterns not always set in and grew, until at the present time there is a strong tendency to restudy and re-evaluate language practices in terms of the ways in which people speak and write.Which of the following statements is not mentioned in the passage?【单选题】

A.It is generally believed that the year 1500 can be set as the beginning of the modern English language.

B.Some other languages had great influence on the English language at some stages of its development.

C.The English language has been and still in a state of relatively constant change.

D.Many classes or groups have contributed to the development of the English language.

正确答案:A

答案解析:根据文章的内容，选项A“普遍认为1500年是现代英语的起点”在文章中没有提及，故为正确答案。文章第2句说“The history of our been a history of constant change…. at times a slow, almost imperceptible change, at other times a violent collision between two languages. ”由此可以推断一些其他的语言对英语的发展有重大影响，选项B符合文章的意思。

7、Life at Aichi UniversityI\'m Yamamoto Mika, a 22 years old Japanese girl. I\'d like to invite you to Aichi University so you can understand my life.Our university has a close relationship with China and my department is the only one of its kind in Japan. My courses include the Chinese language, modern Chinese politics and economics. I love Chinese culture and I have been to Tianjin as an exchange student.In Japan, our courses are divided into compulsory, optional and specialized courses. However, we have a flexible schedule. We can choose classes from a wide range of options.Many students finish the compulsory courses in three years so that they can have one year without any classes. They often use this period of time to study abroad, conduct research and travel. Many students even suspend their study for additional study - abroad opportunities,Japanese universities encourage students to choose their own ways of study, so it is quite easy for us to apply for study suspension.Japanese students participate in various kinds of extracurricular (课外的) activities. They attend clubs from elementary schools, so many students have already been accustomed to clubs when they enter university.Our university now has 42 art clubs and 45 sports clubs. The annual University Festival is the grandest carnival (狂欢节) of Japanese universities. In the festival, students promote their clubs and organize various activities. Our university\'s festival attracted about 150,000 people last year. I really like this festival.When we promote our clubs, we cook "tonnjiru", a kind of pork soup, and sell it to other students at the fair.We also go to different places to interview celebrities (名人) who attend our festival as guests. It is a wonderful experience to talk to those stars face to face.Japanese students like to hold parties. We have two kinds of parties. One is the Mochivori party. If you want to attend this party you have to cook something and take it to the party. The organizer buys drinks and snacks.The other kind of party is the Nomikai, which mainly involves alcohol. We drink something called chu - hai, which is a combination of soda and wine. We also drink Japanese sake (日本米酒) and beer. There are parties for many occasions, like welcoming new students, celebrating victories and birthday parties or just for promoting friendship.The word "compulsory" in paragraph 3 could be best replaced by ____.【单选题】

A.required

B.forced

C.requested

D.demanded

正确答案:A

答案解析:本题有一定难度，考查的是单词的基本意义，但干扰项有一定的干扰性。compulsory和requried都有“必须的”的意思，是近义词，B指“强迫的”，C指“请求的”，D指“需求的，要求的”，最佳答案是A。

8、RobotsThe most sophisticated (先进的) Japanese robots, which have vision systems and work at very high speeds, are still based on American designs. Studies of robots, particularly computer control software, are considered to be generally less advanced in Japan than in America or Europe.Although industrial robots were originally developed as devices for simply handling objects, today their commonest uses are for more skilled work like welding (焊接), spray-painting and assembling components.In Britain robot sales appropriately peaked in 1984, but have been declining ever since. This is partly because British wage rates are too low to make robots financially attractive and partly because engineers now have more experience with robots and are more aware of the difficulties of introducing them effectively.It has been calculated that a robot uses on average about 100 times more energy than a human to do an equivalent job.It is estimated that 20% of all comic book heroes in Japan are robots. This is an enormous number because comics are so popular that they make up a third of all material published in Japan. The reliability of robots is measured in their MTBF or mean time between failures. This has risen from about 250 hours in the mid-1970s to about 10,000 hours today (equivalent to working 18 hours a day for two years). One way robot manufacturers have increased reliability is to test every single component they buy, instead of the normal procedure of just testing a small .sample.The biggest single benefit of introducing robots claimed by Japanese companies is that they increase quality control. One programmed robots can work more accurately and consistently than humans, who can get tired and bored.One disadvantage of using robots is that they consume________.【单选题】

A.too much energy

B.based on American designs

C.they are too costly

D.they are not reliable

E.quality control

F.free of charge

正确答案:A

答案解析:首先根据语法知识，及物动词consume后加名词作宾语，排除选项B、C、D。consume作动词表示“消耗”，剩余选项中只有A选项“too much energy”可以与其搭配。此外，文章第四段It has been calculated that a robot uses on average about 100 times more energy than a human to do an equivalent job也表明：做同样的工作，机器人平均要消耗的能量是人类的100多倍。由此可以肯定A为正确答案。

9、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 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。

10、Sharing SilenceDeaf teenagers Orlando Chavez and German Resendiz have become friends since kindergarten (幼儿园). Together the two boys, who go to Escondido High School in California, have had the difficult job of learning in schools where the majority of the students can speak and hear.Orlando lost his hearing at the age of one. German was borned deaf, and his parents moved from Mexico to find a school where he could learn sign language. He met Orlando on their first day of kindergarten."We were in a special class with about 25 other deaf kids," German remembers. "Before then, I didn\'t know I was deaf and I was different.""Being young and deaf in regular classes was very hard," signs Orlando. "The other kids didn\'t understand us and we didn\'t understand them. But we\'ve all grown up together, and today, I\'m popular because I\'m deaf. Kids try hard to communicate with me."Some things are very difficult for the two boys. "We can\'t talk on the phone. so if we need help, we can\'t call an emergency service," German signs. "And we can\'t order food in a drive - thru."Despite their difficulties, the two boys have found work putting food in bags at a local supermarket. They got their jobs through a "workability" program designed for teenagers from local schools with different types of learning disabilities.German has worked in the supermarket since August, and Orlando started in November."The other people who work here have been very nice to us," Orlando signs. "They even sign sometimes. At first, we were nervous, but we\'ve learned a lot and we\'re getting better.The opportunity to earn money has been exciting, both boys said. After high school, they hope to attend the National Technical Institute for the deaf in New York.The word emergency in paragraph 5 is closest in meaning to ____.【单选题】

A.food

B.alarm

C.crisis

D.quick

正确答案:C

答案解析:本题难度不大，干扰项干扰不强，考生会很快确定答案。emergency指“紧急”和crisis“危机，紧急关头”是近义词。B项alarm指“警戒”，最佳答案是C。
