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、March MadnessFor the rest of the month, an epidemic (流行病) will sweep across the US. It will keep kids stay home from school. College students will ignore piles of homework. Employees will suddenly lose their abilities to concentrate.The disease, known as "March Madness", refers to the nearly 65 teams in US men\'s college basketball tournament, it begins on March 15 and lasts through the beginning of April. Teams compete against each other in a single elimination tournament that eventually crowns a national champion.Nearly 20 million Americans will become the prisoners of basketball festival madness.The fun comes partly from guessing the winners for every game. Friends compete against friends, husbands against wives, and colleagues against bosses.Big name schools are usually favored to advance into the tournament. But each year there are dark horses from little - known universities.This adds to the madness. Watching a team from a school with 3,000 students beat a team from a school with 30,000, for many Americans, is an exciting experience. Last year the little - known George Mason University was one of the final four teams. Many people had never even heard of the university before the tournament.College basketball players are not paid, so the game is making a name for their university and themselves. But ft doesn\'t mean money isn\'t involved. About $ 4 billion will be spent gambling on the event. According to Media Life magazine, the event will draw over $ 500 million in advertising revenue this year, topping the post - season revenue, including the NBA (全国篮球协会).Which of the following is NOT an instance of "March Madness"? ____【单选题】

A.Kids run away from school.

B.Husbands kiss their wives.

C.College students keep homework piling up.

D.Employees can\'t concentrate on their work.

4、Migrant (移民的) WorkersIn the past twenty years, there has been an increasing tendency for workers to move from one country to another. While some countries have restricted most jobs to local people, others have attracted and welcomed migrant workers. This is particularly the case in the Middle East, where increased oil incomes have enabled many countries to call in outsiders to improve local facilities. Thus the Middle East has attracted oil workers from the USA and Europe. It has brought in workers from many countries, including South Korea and Japan.In view of the difficult living and working conditions in the Middle East, it is not surprising that the pay is high to attract suitable workers. Many engineers and technicians can earn at least twice as much money in the Middle East as they can in their own country, and this is a major attraction .Sometimes a disadvantage has a compensating (补偿的) advantage. For example, the ______ living conditions often lead to increased friendship when workers have to depend on each other for safety and comfort. In a similar way, many migrant workers can save large sums of money partly because of the lack of entertainment facilities. The work is often complex and full of problems but this merely presents challenge to engineers who prefer to find solutions to problems rather than do routine work in their home country.One major problem which affects migrant workers in the Middle East is that their jobs are temporary ones. They are nearly always on contract, so it is not easy for them to plan ahead with great confidence. This is to be expected since no country welcomes a large number of foreign workers as permanent residents. In any case, migrant workers accept this disadvantage, along with others, because of the considerable financial benefits which they receive.【单选题】

A.necessary

B.normal

C.difficult

D.good

正确答案:C

答案解析:第三段第一句是本段的主题句，意思是：有时候不利条件也会产生有利的因素。接着应是具体说明。空格所在句的大概意思是：当工人们不得不彼此依赖以寻求安全和心理安慰时，大家的友谊随之增深了。这是一种得到补偿的有利的东西，那么空格应填入的最合适的词显然是difficult（困难）。necessary:必需的；normal:正常的；good:好的。将这些选项填人后，句子前半部分表达的不是不利的因素，而是有利的因素，跟主题句不能构成连贯的语段。

5、African wild dogFinding a babysitter while you go out to work is, for example, an inconvenience. For the African wild dog, one of the continent\'s most endangered carnivores （食肉动物), it\'s a matter of life and death. A new research shows that once packs (兽群) fall below a certain size, they are not enough animals to both hunt food and stay at home protecting the young.The African wild dog has declined drastically over the past century. Habitual loss (栖息地的丧失), persecution and unexplained outbreaks of disease have all been blamed. Only 3, 000 to5,000 animals remain, and the species is expected to go extinct within decades if the trend continues.Other large carnivores such as the spotted hyena (鬣狗) face similar pressures, yet are not declining. Now Franck Courchamp of Cambridge University has found a reason why. The dog\'s weakness lies in its social organization.Within each pack of up to 20 adults and pups, only the dominant male and female breed. The remaining animals help raise the pups, cooperating to hunt prey and defend the kill from other carnivores.Because pups can\'t keep up on a hunt, large packs leave an adult behind to protect them from predators (捕猎者), which include lions and hyenas. But leaving a babysitter also carries costs. A smaller hunting party is less able to tackle large prey and to defend the kill. There is also one less stomach in which to carry food back to the den, and one more mouth to feed when they get there.Courchamp investigated this awkward trade-off (权衡) by modeling how the costs of a babysitter change with decreasing pack size. This showed that packs of more than five adults should be able to feed all the pups and still spare a babysitter. But with smaller packs, either the hunting or the babysitting suffers, or the animals have to compensate by increasing the number of hunting excursions which itself carries a cost to the pack.Field observations in Zimbabwe supported the model. Packs of five animals or fewer left pups unguarded more frequently than larger packs did. There was also evidence that when they did leave a babysitter, they were forced to hunt more often.A pack which drops below a critical size becomes caught in a vicious circle (恶性循环), says Courchamp, who is now at Paris-Sud University. "Poor reproduction and low survival further reduces pack size, culminating in (最终造成) failure of the whole pack. " And deaths caused by human activity, says Courchamp, may be what reduce pack numbers to below the sustamable threshold. Mammal ecologist Chris Carbone at London\'s Institute of Zoology agrees. Maintaining the integrity of wild dog packs will be vitalin preserving the species, he says.The size of a pack must be big enough for it to survive.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:答案的依据是文章最后一段开头，因此这个命题是正确的。

6、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。

7、Ants as a Barometer of Ecological ChangeAt picnics, ants are pests. But they have their uses. In industries such as training, farming and forestry, they can help gauge the health of the environment by just crawling around and being antsy.It has been recognized for decades that ants-which are highly sensitive to ecological change can provide a near-perfect barometer of the state of an ecosystem. Only certain species, for instance, will continue to thrive at a forest site that has been cleared of trees. Others will die out for lack of food. And still others will move in and take up residence.By looking at which species populate a deforested area, scientists can determine how "stressed" the land is. They do this by sorting the ants, counting their numbers and comparing the results with those of earlier surveys. Ants are used simply because they are so common and comprise so many species.Where mine sites are being restored, for example, some ant species will recognize the stripped land more quickly than others. _____. Australian mining company Capricorn Coal Management has been successfully using ant surveys for years to determine the rate of recovery of land that it is replanting near its German Creek mine in Queensland.Ant surveys also have been used with mine-site recovery projects in Africa and Brazil, where warm climates encourage dense and diverse ant populations. "We found it worked extremely well there," says Jonathan Majer, a professor of environmental biology. Yet the surveys are perfectly suited to climates throughout Asia, he says, because ants are so common throughout the region. As Majer puts it: "That\'s the great thing about ants. "Ant surveys are so highly-regarded as ecological indicators that governments worldwide accept their results when assessing the environmental impact of mining and tree harvesting. Yet in other businesses, such as farming and property development, ant surveys aren\'t used widely.Why not? Because many companies can\'t afford the expense or the laboratory time needed to sift results for a comprehensive survey. The cost stems, also, from the scarcity of ant specialists. Employing those people are expensive. 【单选题】

A.This allowed scientists to gauge the pace and progress of the ecological recovery.

B.Yet in other businesses, such as farming and property development, ant surveys aren\'t used widely.

C.Employing those people are expensive.

D.They do this by sorting the ants, counting their numbers and comparing the results with those of earlier surveys.

E.The evolution of ant species may have a strong impact on our ecosystem.

F.Others will die out for lack of food.

正确答案:A

答案解析:选项A中的ecological recovery与前面一句中的recognize相呼应，提示选项A的句子是前面句子的后续句。

9、Money or Friendship or Both1. Friends and money don\'t mix. It\'s a dangerous combination since a fight over money is one of the fastest ways to end a friendship. But what if a friend asks you to tend him or her some money? If you don\'t lend your friend the money, you risk losing the friend. If you do lend your friend the money, you risk losing both the friendship and your money.2. We have to face facts, so here are some situations you might run across with your buddies (伙伴) and some helpful tips (忠告) on how to deal with them. Thinking about why this person needs to borrow in the first place. If he is always living beyond his means, it is his fault, not yours. Any Sensible person would not put himself in a position of debt so often. So simply say "no" to this friend. Even if your friend really needs that money for emergency use and you are willing to help him, before you dive into your pocket, follow this reality check: Do you have the extra money? Are you sure you don\'t need it? Are you willing to write off that amount if it\'s not returned? If your answers are negative, do yourself a favor and say "no".3. Let\'s assume you can\'t stand saying "no" to your friend because you don\'t want him living off cat food. What do you do? Write down these details on a sheet of paper before opening up your wallet:Amount of the loan.Date of the loan.Time of repayment.Amount of interest (if any).Lender\'s and borrower\'s signature.This will at least keep the borrower from forgetting the loan so easily, If your friend\'s loan is past due, it\'s important that you ask him－and it\'s actually not rude. The longer you wait, the more you are brood (忧伤), and the more your resentment builds.4. You can send him a friendly reminder via E - mail. Tell him something like "I\'m going over my bank account and I\'m just wondering when we\'ll be able to settle that money thing." E - mail saves you from an uncomfortable face - to - face confrontation. There is almost no chance of turning a bad reaction into an argument. Unlike a public conversation, an E - mail message will always be private.5. After asking two or three times, you might have to write it off. That\'s what happens. If he just doesn\'t have the money or is unwilling, then what kind of friend is that?Paragraph 2 ____【单选题】

A.Time to Break off a Friendship

B.Unconditional Assistance to Friends in Need

C.Things to Consider When You Have to Say "No" to Your Friend

D.Things to Think over When You Don\'t Want Your Friend to Eat Cat Food

E.Strategies for Borrowing Money

F.Advantages of E - mail in Handling Money Issues

正确答案:C

答案解析:本题难度不大，主旨句比较好确认，就是第二段的第一句，谈到我们必须面对事实，当你在某些情况下遇到你朋友跟你借钱时，下面有几条忠告来帮助你应对这种状况。换句话说第二段主要给出了如何对朋友说“不”的几条忠告。回来看选项，比较明显，C项Things to Consider When You Have to Say "No" to Your Friend，就是对本段的概括，所以答案是C。

10、A Country\'s Standard of LivingThe "standard of living" of any country means the average person\'s share of the goods and services the country produces. A country\'s standard of living, therefore, ____ first on its capacity to produce wealth. "Wealth" in this sense is not money, for we do not live on money but on things that money can buy: "goods such as food and clothing", and "services" such as transport and entertainment.A country\'s capacity to produce wealth depends upon many factors most of which have an effect on one another. Wealth depends to a great extent upon a country\'s natural resources. Some region of the world are well supplied with coal and minerals, and have fertile (肥沃的) soil and a favorable climate, other regions possess none of them.Next to natural resources comes the ability to turn them to use, China is perhaps as rich as the USA in natural resources, but suffered for many years from civil and external wars, For this and other reasons it was unable to develop her resources. Sound and stable political conditions, and freedom from foreign invasions, enable a country to develop its natural resources peacefully and steadily, to produce more wealth than other country.A country\'s standard of living does not only depend upon the wealth that is produced and consumed within its own borders, but also upon what is directly produced through international trade. For example, Britain\'s wealth in foodstuffs and other agricultural products would be much less if she had to depend only on those grown at home. Trade makes it possible for her surplus (剩余的) manufactured goods to be traded abroad for the agricultural products which would otherwise be lacking. A country\'s wealth is, therefore, much influenced by its manufacturing capacity, providing that other countries can be found ready to accept its manufactures.【单选题】
