Practice 2　　The destiny of wild places in the 21 century can be read in the numbers. The pressure to exploit the world’ s remaining wilderness for natural resources, food and human habitation will become overwhelming. But bulldozers and chain saws aren’t the only threats. A new menace has emerged from the least likely quarter; in many cases, the very people who care most passionately about empty places are hastening their demise.　　Backcountry activities have become extremely trendy in the U. S., a fad that has been eagerly abetted by Madison Avenue. These days it’s impossible to turn on a television or open a magazine without being assaulted by a barrage of ads that use skillfully packaged images of wilderness activities to rev the engine of consumerism. Disconcerting though this development may be, it happens to come with a substantial upside; because wilderness is now esteemed as something precious and/or fashionable, wild places are more often being rescued from commercial exploitation. But if the wilderness fad has made it easier to protect wild country from development, it has made it harder to protect wild country from the exploding ranks of wilderness enthusiasts. Increasingly, places once considered enduringly back of beyond are now crowded with solitude seekers. As wilderness dwindles and disappears, more is at stake than the fate of endangered species. Other, less tangible things stand to be lost as well. Empty places have long served as a repository for a host of complicated yearnings and desires. As an antidote to the alienation and pervasive softness that plague modern society, there is no substitute for a trip to an untrammeled patch of backcountry, with its attendant wonders, privation and physical trials.

    Human and the Earth

    In terms of the evolution of life on Earth,human beings have just arrived.Despite their shori time on Earth,however,people have brought about enormous changes to the surface of the planet一changes far out of proportion to the interval of time they have occupied it.
    People have more control over their surroundings than any other species on Earth.With the combination of intelligence and manual skill(allowing us to make and use tools),people have found ways to use plant and animal resources,mineral ores,fuels,and many other materials and resources from the Earth.
    As the number of people on Earth increases,it becomes increasingly difficult for the population to survive on the resources of the land.The amount of land is limited.Although agricultural production can be increased by use of machinery such as tractors and the addition of fertilizer,the land ultimately can produce only so much food and no more.
    As the human population grows,people consume more.Clearly,some locations on Earth already have too many people;in many of these areas,future increases will surely bring about more poverty and suffering. Yet people in rich nations use proportionally far more of the available resources than people in poorer nations.As they consume these resources without restraint,they also waste large amounts of them.
    People are only a very small fraction of all the living things on the planet.Yet their numbers create a drain on resources that can't be renewed.For example,the amount of water on Earth is limited,this water is cleaned through natural processes.However,the natural processes for filtering water can clean only a certain amount of water by removing the pollution.Likewise,a limited amount of petroleum can be found under the Earth's surface.Petroleum is a valuable resource.Should people use it up to manufacture petrol for automobiles?As people work to control the planet and make life comfortable,are they using up resources that are needed for their survival?

    in terms of the evolution of life on Earth,the history of human beings is_______.
    A:very short
    B:very long
    C:as long as that of other animals
    D:as long as that of the Earth

    答案：A
    解析：
    文章第一段第一句话提到“就地球上生命的进化而言，人类是姗姗来迟者”，因此比较而言，人类的历史并不长。选项A是正确的。
    从文章第二段第二句话“With the combination of intelligence and manual skill...”我们知道选项A和B都是正确的，因此选择D项。
    文章第三段提到，土地的总量是有限的。虽然使用拖拉机等机械和施用化肥可以提高农业产量，但是土地最终所能产出的粮食只有那么多，不会再增加。因此只有选项C是正确的。
    文章第四段第三句说富裕国家的人们所使用的能源在比例上远远大于贫穷国家的人们。选项C中提到的“发达国家的人们”最符合题意。
    根据文章最后一段关于资源的描述我们可以发现选项A、B、C都是正确的，只有选项D的表述错误，因此选择D项。

    cessed,or prepared.For example,many farmers spray chemicals on crops to kill weeds and insects.Some
    people may have a bad reaction to those chemical、when they eat the crops.
    Some plants and animals contain natural poisons that are harmful to people.These includo certain kinds
    of seafood,grains,nuts,seeds,beans,and mushrooms.
    When people handle food properly,the risk of food poisoning is very small.Microorganisms multiply rapidly
    in dirty places and in warm temperatures.This means that people should never touch food with dirty hands or
    put food on unwashed surfaces.Food should be kept in a refrigerator to stop microorganisms from growing,

  • 第5题：

    In any country, the "standard ofliving" means the average person′s share of the goods and services whichthe country produces. Therefore, a country′s standard of living depends firstand foremost on its capacity to produce wealth. "Wealth" in thissense is not money, but "goods" such as food and clothing, and"services" such as transport and entertainment.
    The capacity to produce wealth depends uponmany factors, most of which have an effect on one another. To a great extent,wealth depends upon a country′s natural resources, such as coal, gold, andother minerals, water supply and so on. Some regions of the world are wellsupplied with coal and minerals, and some are not.
    Next to natural resources comes the abilityto turn them to use. Some countries are perhaps well off in natural resources,but unable to develop their resources. They suffered for many years from civiland external wars. Peaceful political and stable conditions enable a country todevelop its natural resources effectively, and to produce more wealth thananother country equally well served by nature but less well ordered. Anotherimportant factor is the technical efficiency of a country′s people.Industrialized countries that have trained numerous skilled workers andtechnicians produce wealth more than countries whose workers are largelyunskilled.
    A country′s standard of living does notonly depend upon the wealth that is produced and consumed within its ownborders, but also upon what is indirectly produced through international trade.
    For instance, Britain′s wealth isfoodstuffs and other agricultural products would be much less if she had todepend only on those grown at home. Trade makes it possible for her surplusmanufacture goods to be traded abroad for the agricultural products. In thisaspect, a country′s wealth is much influenced by its manufacturing capacity,provided that other countries can be found ready to accept its manufactures.
    The standard of living in a countryis determined by ______.

    A.its goods and services
    B.the type of wealth produced
    C.how well it can create wealth
    D.what an ordinary person can share

    答案：C
    解析：
    细节题。第一段第一句指出standardof living的定义，第二句“Therefore，a country’s standard of living depends first and foremost on its capacity toproduce wealth．”以及第三句指出什么决定了 standard of living．即决定一个国家生活标准的是这个国家创造商品和服务的能力(the capacity to produce goods and services)，故选C。

    Camping Camping wild is a wonderful way to experience the natural world and， at its best， it makes little environmental influence. But with increasing numbers of people wanting to escape into the wilderness， it is becoming more and more important to camp unobtrusively （不引人注目地） and leave no mark. Wild camping is not permitted in many places， particularly in crowded lowland Britain. Wherever you are， find out about organizations responsible for managing wild spaces， and contact them to find out their policy on camping and shelter building. For example， it is fine to camp wild in remote parts of Scotland， but in England you must ask the landowner's permission， except in national parks. Camping is about having relaxation， sleeping outdoors， experiencing bad weather， and making do without modern conveniences. A busy， fully-equipped campsite （野营地） seems to go against this， so seek out smaller， more remote places with easy access to open spaces and perhaps beaches. Better still， find a campsite with no road access： walking in makes a real adventure. Finding the right spot to camp is the first step to guaranteeing a good night's sleep. Choose a campsite with privacy and minimum influence on others and the environment. Try to use an area where people have obviously camped before rather than creating a new spot. When camping in woodland， a void standing dead trees， which may fall on a windy night. Avoid animal runs and caves， and possible homes of biting insects. Make sure you have most protection on the windward side. If you make a fire， do so downwind of your shelter， always consider what influence you might have on the natural world. Avoid damaging plants. A good campsite is found， not made — changing it should be unnecessary. Camping wild is a wonderful way to experience the natural world.（）

    B

    Practice 5　　 (The candidate chooses one topic and speaks about it for one minute.)　　A　Advertising: the importance of using celebrities to endorse products　　B　Human Resources: how to retain high achievers on a company’s staff　　C　Business Strategy: the factors involved in influencing market trends rather than reacting to them

    正确答案： 【参考范例】
    If you chose A: (three possible answers)
    a. Many factors will influence consumers’ choices and desires, which are constantly changing, according to their needs and styles that have caught the popular imagination. Sellers of goods and services court, entice, and implore consumers. Using celebrities to endorse products has been one of the most effective advertising gimmicks. People tend to think negative advertising does not sway them but the truth is that it does. A great number of people always copy celebrities’ behavior. Celebrity endorsement serves a model for community.
    b. Using celebrities to endorse products is very important for advertising. If a celebrity endorses a product or service, he or she says that they use and like it in an advertisement. Celebrity endorsements show their formal support or approval for someone or something. If a famous person buys a product, many consumers tend to follow. It is even more so, when consumers are not confident enough about their ability to identify exactly what it is.
    c. The reason why many people always do the same as the famous people have done is that they trust celebrity. Although they may distrust advertisement, they will possibly trust the celebrity. Celebrities’ behavior has a great effect on consumers. Therefore, using celebrities to endorse products is beneficial to the company, for it gives the company an advantage, improves its reputation, and helps the company promote sales. Therefore, it is very significant for companies to use celebrities to endorse products, in advertising.
    If you chose B: (two possible answers)
    a. Retaining high achievers on a company’s staff has been used as a market-driven approach to talent retention. Although once rare in business, open competition for other companies’ people is presently an accepted fact. Fast-moving markets require fast-moving organizations to be continually refreshed with new talent. However, no one will be willing to see talent leave; whenever a good employee walks, the business takes a hit. It’s useless to hope that by tinkering with compensation, career paths, and training efforts, you can wall off your company from today’s labor market.
    b. Besides monetary compensation, an alternative to retain high achievers on a company’s staff is a market, which is a driven approach to retention based on the assumption that long-term across-the-board loyalty is neither possible nor desirable. By trying hard to figure out which employees you need to retain and for how long, you can take advantage of highly targeted programs to keep the required talent in place. Most companies today depend on compensation to build loyalty, which is only one of many effective retention mechanisms. Jobs can be redesigned to reduce turnover. For example, UPS retain many more drivers by shifting the tedious and laborious job of loading trucks to other employees.
    If you chose C:
    I think the factors involved in influencing market trends are as follows: Consumer, Cost, Convenience, and Communication. The key difference is that under modern marketing, profits are regarded as a function to provide customer benefits, whereas under the old marketing, profits were seen as a function of sales. To conclude, marketing is a concept, a business process as well as a set of activities. This total set of marketing activities, integrated into a unified program, are sometimes called the marketing mix, which today, in addition to profitability, typically includes a lot of broader objectives relevant to current social concerns. These concerns now concentrate on areas like protection of the physical environment, product safety, and equal employment opportunity.

    As the number of people on Earth increases,it becomes increasingly difficult for the population to survive on the resources of the land.The amount of land is limited.Although agricultural production can be increased by use of machinery such as tractors and the addition of fertilizer,the land ultimately can produce only so much food and no more.
    As the human population grows,people consume more.Clearly,some locations on Earth already have too many people;in many of these areas,future increases will surely bring about more poverty and suffering. Yet people in rich nations use proportionally far more of the available resources than people in poorer nations.As they consume these resources without restraint,they also waste large amounts of them.
    People are only a very small fraction of all the living things on the planet.Yet their numbers create a drain on resources that can't be renewed.For example,the amount of water on Earth is limited,this water is cleaned through natural processes.However,the natural processes for filtering water can clean only a certain amount of water by removing the pollution.Likewise,a limited amount of petroleum can be found under the Earth's surface.Petroleum is a valuable resource.Should people use it up to manufacture petrol for automobiles?As people work to control the planet and make life comfortable,are they using up resources that are needed for their survival?

    Which of the following statements about resources on Earth is not correct?
    A:They can not be renewed.
    B:Water is a kind of resource which can not be renewed.
    C:Some of the resources are valuable.
    D:Many resources can be recycled so we don't need to worry about them.

    答案：D
    解析：
    文章第一段第一句话提到“就地球上生命的进化而言，人类是姗姗来迟者”，因此比较而言，人类的历史并不长。选项A是正确的。
    从文章第二段第二句话“With the combination of intelligence and manual skill...”我们知道选项A和B都是正确的，因此选择D项。
    文章第三段提到，土地的总量是有限的。虽然使用拖拉机等机械和施用化肥可以提高农业产量，但是土地最终所能产出的粮食只有那么多，不会再增加。因此只有选项C是正确的。
    文章第四段第三句说富裕国家的人们所使用的能源在比例上远远大于贫穷国家的人们。选项C中提到的“发达国家的人们”最符合题意。
    根据文章最后一段关于资源的描述我们可以发现选项A、B、C都是正确的，只有选项D的表述错误，因此选择D项。

    Food Poisoning

    Food sometimes gets poisoned with harmful things,A person who eats such food can get an illness called
    food poisoning. Food poisoning is usually not serious,but some types are deadly.The symptoms of food poi-
    soning usually begin within hours of eating the poisoned food.Fever is one of the most common symptoms.
    Certain microorganisms（微生物）cause most types of food poisoning. Bacteria and other microorganisms
    can poison eggs,meat,vegetables,and many other foods.After entering the body,these tiny living things re-
    lease（释放）poisons that make people sick.
    Some chemicals can also cause food poisoning. They are often added to food while it is being grown,pro-
    cessed,or prepared.For example,many farmers spray chemicals on crops to kill weeds and insects.Some
    people may have a bad reaction to those chemical、when they eat the crops.
    Some plants and animals contain natural poisons that are harmful to people.These includo certain kinds
    of seafood,grains,nuts,seeds,beans,and mushrooms.
    When people handle food properly,the risk of food poisoning is very small.Microorganisms multiply rapidly
    in dirty places and in warm temperatures.This means that people should never touch food with dirty hands or
    put food on unwashed surfaces.Food should be kept in a refrigerator to stop microorganisms from growing,
    Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered
    with chemicals before eating it.Finally,people should not eat wild mushrooms or other foods that grow in the
    wild.Some of these foods may contain natural materials that are poisonous to humans.In addition,some types
    of fish can be poisonous.
    Most people recover from food poisoning after a few days of resting and drinking extra water. If people
    eat natural poisons,they must go to the hospital right away to have their stomachs emptied.

    It can be inferred from the passage that_______________.
    A:natural materials are safe in food processing
    B:chemicals are needed in food processing
    C:food poisoning can be kept under control
    D:food poisoning is out of control

    答案：C

    Camping Camping wild is a wonderful way to experience the natural world and， at its best， it makes little environmental influence. But with increasing numbers of people wanting to escape into the wilderness， it is becoming more and more important to camp unobtrusively （不引人注目地） and leave no mark. Wild camping is not permitted in many places， particularly in crowded lowland Britain. Wherever you are， find out about organizations responsible for managing wild spaces， and contact them to find out their policy on camping and shelter building. For example， it is fine to camp wild in remote parts of Scotland， but in England you must ask the landowner's permission， except in national parks. Camping is about having relaxation， sleeping outdoors， experiencing bad weather， and making do without modern conveniences. A busy， fully-equipped campsite （野营地） seems to go against this， so seek out smaller， more remote places with easy access to open spaces and perhaps beaches. Better still， find a campsite with no road access： walking in makes a real adventure. Finding the right spot to camp is the first step to guaranteeing a good night's sleep. Choose a campsite with privacy and minimum influence on others and the environment. Try to use an area where people have obviously camped before rather than creating a new spot. When camping in woodland， a void standing dead trees， which may fall on a windy night. Avoid animal runs and caves， and possible homes of biting insects. Make sure you have most protection on the windward side. If you make a fire， do so downwind of your shelter， always consider what influence you might have on the natural world. Avoid damaging plants. A good campsite is found， not made — changing it should be unnecessary. Wild camping is always permitted in many places.（）

    Although there is disagreement within the scientific community about the extent of global warming, humans would be playing with fire if we were to ignore the danger it poses .As individuals, we can reduce our reliance on fossil fuels, use less electricity and adopt lifestyles that minimize the use of natural resources. On the governmental level, most of the world’s industrialized nations have pledged to cut gas emissions under the Kyoto Agreement in 1997.

    正确答案：
    虽然科学界对全球变暖的影响程度尚有歧见,但若人类对温室效应造成的危险置之不理,无异于玩火自焚。为避免温室效应加剧,从个人角度来看我们可以做的就是降低对化石燃料的依赖、减少用电,并采取最不耗损自然资源的生活方式。在政府这个层面,世界大部份的工业化国家,已在一九九七年所签定的京都议定书中,宣誓将做到气体排放减量。
