Practice 3　　The shotgun marriage of chemistry and engineering called “Nanotechnology” is ushering in the era of serf-replicating machinery and serf-assembling consumer goods made from cheap raw atoms.　　Nanotechnology is molecular manufacturing or, more simply, building things one atom or molecule at a time with programmed baroscopic robot arms. A nanometer is one billionth of a meter (3-4 atoms wide).　　Utilizing the well understood chemical properties of atoms and molecules (how they “stick” together), nanotechnology proposes the construction of novel molecular devices possessing extraordinary properties. The trick is to manipulate atoms individually and place them exactly where needed to produce the desired structure. This ability is almost in our grasp. The anticipated payoff for mastering this technology is far beyond any human accomplishment so far.　　By treating atoms as discrete, bit-like objects, molecular manufacturing will bring a digital revolution to the production of material objects. Working at the resolution limit of matter, it will enable the ultimate in miniaturization and performance. By starting with cheap, abundant components-molecules-and processing them with small, high-frequency, high-productivity machines, it will make products inexpensive. Design computers that each executes more instructions per second than all of the semiconductor CPUs in the world combined.　　Nanotechnology will reverse the harm done by the industrial revolution. Imagine being able to cure cancer by drinking a medicine stirred into your favorite fruit juice. Imagine a supercomputer no bigger than a human cell Imagine a four-person, surface-to-orbit spacecraft no larger or more expensive than the family car. These are just a few products expected from nanotechnology.　　Humanity will be faced with a powerful, accelerated social revolution as a result of nanotechnology. In the near future, a team of scientists will succeed in constructing the first nano-sized robot capable of self-replication. Within a few short years, and five billion trillion nano-robots later, virtually all present industrial processes will be obsolete as well as our contemporary concept of labor. Consumer goods will become plentiful, inexpensive, smart, and durable. Medicine will take a quantum leap forward, space travel and colonization will become safe and affordable.　　For these and other reasons, global life styles will change radically and human behavior will be drastically impacted. The world is on the brink of a new technological revolution beyond any human experience. A new, more powerful industrial revolution capable of bringing wealth, health, and education, without pollution, to every person on the planet. No longer will forest need to be cut or smoke spewed into the air. This is the promise of nanotechnology.　　A nanometer is one billionth of a meter. That’s a thousand, million times smaller than a meter. If you blew up a baseball to the size of the earth, the atoms would become visible, about the size of grapes. Some 3-4 atoms fit lined up inside a nanometer.

    Practice 7　　Task Sheet:　　A: WHAT IS IMPORTANT WHEN...?　　Aiming to improve career prospects　　● Reading business articles　　● Learning a foreign language　　●…______　　B: WHAT IS IMPORTANT WHE...?　　Deciding how to transport goods　　● Destination　　● Speed______　　●…　　C: WHAT IS IMPORTANT WHEN...?　　Purchasing new machinery　　● Level of automation　　● Maintenance requirements　　●…

    正确答案： 【参考范例】
    If you choose A:
    When aiming to improve career prospects, you need to realize the importance of reading business articles. You need to understand what is going on in the business world, what is the latest trend in making deals. Learn more about financing and the industry you are in. Try to familiarize yourself with more management skills concerning time management, project management, HR management, PR management, etc.
    Secondly, learn a foreign language will also help improve career prospects. Grasping a foreign language means that better communication with foreign investors and clients. You will be able to read business articles published in foreign newspapers/magazines. When attending international conferences, you will have no problem in understanding keynote speeches at such conferences.
    If you choose B:
    When deciding how to transport goods, first of all, you need to figure out how far away the destination is so that you can better decide on the means for transporting goods. For instance, shipping is often considered the most economical way to transport goods of large quantities to far  destinations. As the express highways develop rapidly in our country, transportation by truck has won increasing popularity as it can offer door-to-door delivery services for most destinations within the country.
    Another factor to be taken into account when deciding how to transport goods is speed. Although the fastest way is by air, transportation by air has also its disadvantages since it is more expensive than other means of transportation and transporting goods in very large sizes is very difficult.
    If you choose C:
    When purchasing new machinery, it is important to know about the level of automation, that is whether it is fully automated or partly automated. In case that it is only partly automated, you need to think about how to operate it and whether the workers need to be trained to operate it. If it is necessary to offer some training, you need to consider the selection of trainers. Moreover,   the training cost and who will pay for it needs to be taken into consideration.
    Furthermore, it is necessary to know whether it is easy to maintain the machinery and the relevant requirements, like how often does it require a routine maintenance check, how often does it require an overhaul, whether it is easy to get spare parts or replacement parts, whether spare parts are included in the overall price for the machinery, etc.

    Practice 6　　You should spend about 40 minutes on this task.　　Write about the following topic:　　An increase in production of consumer goods results in damage of the natural environment, what are the causes and possible solutions?　　Give reasons for your answer and include any relevant examples from your own knowledge or experience.　　Write at least 250 words.

    正确答案： 【参考范文】
    An increase in production of consumer goods results in damage of the natural environment, what are the causes and possible solutions?
    A hot debate goes on and on for effective remedies to solve the plight between the increasing consumer goods and environmental problems. And so much attention paid on this difficult issue. From my perspective, I believe that some major environment impairing is tightly related to modern consumerism and I will put forward solutions then.
    To begin with, the fast step of modern lifestyle contributes to the rubbish increase, since so many people prefer the use of disposable items for the convenience's sake. As a result, excessive garbage has been accumulating on our earth. The favor of disposables, hence, should take the blame. Products are ready to be thrown away since they have been manufactured. Subsequently, either the creation or dumping of popular products bringing great harm to the residents nearby since that they will release tremendous poisonous elements .in the air, soil, even in the sea. While, even when people come to realize their evil, they remain pursuing their profits regardless of any side effects to the environment.
    Second, the relentless pursuit of consumerism also contributes a lot to the issue mentioned above. For example, animals are sacrificed to devote their fur or leather for human's vanity, giving rise to the lost of bio-diversification danger. Besides, the crazy hunger for luxury goods leading to the shrinking of Amazon forest or mangrove along the shores, results in abnormal climate world-wide. Motor vehicle and aircraft are the most notorious examples in this regard. A vicious circle might be just around the corner if man does not learn how to resist the endless obsession of consumerism. The global warming is a sign of future risk and we should take measures to solve the problem.
    In response to solve this increasing adverse effect, some viable solutions must be put forward.  To begin with, carbon-footprint cutting, committed by political figures and scientists globally, is a good start. Then, If possible, government should take stronger and harsher measures to combat the littering behavior, such as hefty fines. Last but not least, people must be called on to live simpler life—less luxurious consumer goods.
    All in all, as is indicated above, it is inevitable that the higher pressure of population and over—industrialization will lead to larger scale of consumer goods production. In a whole, the major reasons why consumer goods production deteriorates the ecosystem and measures proposed have been listed above.

    Practice 9　　In the United States most people are simultaneously consumers and producers; they are also voters who help influence the decisions of the government. The mixture among consumers, producers and government changes constantly, making a dynamic rather than a static economy. In the last decade consumers have made their concern known and government has responded by creating agencies to protect consumer interests and promote the general public welfare. In another development, the population and the labor force have moved dramatically from farms to cities, from the fields to the factories, and above all to service industries, thus providing more personal and public services. In today's economy these providers of services far outnumber producers of agricultural and manufactured goods.　　Generally, there are three kinds of businesses: (1) those started and managed personally by single owners or single entrepreneurs; (2) the partnership where two or more people share the risks and rewards of a business, and (3) the corporation where shareholders as owners can buy and sell their shares at any time on the open market. This latter structure, by far the most important, permits the amassing of large sums of money by combining investment of many people, making possible large-scale enterprises.

    在美国,大多数人既是消费者,同时又是生产者,而且还是能对政府施加影响的选民。消费者、生产者和政府三者的混合经常发生变化,因而产生的是动态经济而不是静态经济。在过去十年里,消费者公开表明了他们所关心的种种问题,而政府则据此设立了各种机构来保护消费者的利益,改善公共福利事业。出现的另一种新情况是,人口和劳动力大量从农村迁移到城市,从农田进入工厂,尤其是进入服务行业,从而为个人和公众提供了更多的服务。在当今的经济中,服务行业的从业人员大大超过农业和制造业的生产者。
    一般说来,企业分为三种:(一)个体业主和个体企业家开办经营的企业;(二)两人或两人以上共同承担风险、分享赢利的合伙企业;(三)股份公司,股东作为公司拥有人任何时候都可以在公开市场上买卖公司股票。最后的那一种企业最为重要,因为股份公司可以把许多人的投资筹集到一起聚成巨额资金,从而得以开办大型企业。

    Practice 7　　While there are a few different conceptualizations of globalization, researchers seem to be in agreement that there are at least three dimensions of globalization: economic, political and cultural. The economic aspects of globalization stem from the spread of the capitalist world economy and the resulting expansion of goods and services. The need for cheap raw materials, cheap labor and new markets saw the expansion of the capitalist world economy from one that was primarily Eurocentric to one that encompassed the entire world. This process was achieved by various means and often involved overcoming political resistances in the new markets. The political aspects of globalization involved establishing control over markets and raw materials through either the use of direct military power or the establishment of international institutions that control such markets.
