考题【 The Internet ofthings (IoT) is the inter-networking ofphysical devices，vehicles ，buildings ，and other items embedded with electronics ，software，sensors，actuators，and network connectivity which enable these objects to collect and exchange data. In 2013 the Global Standards Initiative on Internet ofThings (IoT-GSI) defined the 10T as a global infrastructure for the information society， enabling advanced services by interconnecting (physical and virtual) things based on existing and evolving interoperable information and communication technologies and for these purposes a thing is an object ofthe physical world (physical things) or the information world (virtual things). which is capable ofbeing identified and integrated into communication networks. The 10T allows objects to be sensed or controlled remotely across existing network infrastructure ，creating opportunities for more direct integration of the physical world into computer - based systems，and resulting in improved efficiency. Accuracy and economic benefit in addition to reduced human intervention. When IoT is augmented with sensors and actuators，the technology becomes an instance of the more general class of cyber physical systems，which also encompasses technologies such as smart grids，virtual power plants ，smart homes ，intelligent transportation and smart cities. Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Intemet infrastructure. Experts estimate that the 10T wi l1 consist of about 30 bi l1ion objects by 2020. 】 Based on the paragraph above，we know that the applications ofthe 10T include (98) . RFID technology makes it possible to automatically (99) every object on the Internet ofthings，and is the foundation ofnetworking. From the industry point of view，IoT is mainly involved in industries including (100).A. environmental monitoring B.intelligent transportation C.energy management D.all ofthe above A. identify B.find C. track D. encrypt A. electronics B.communication C. software D. all of the above

考题 Who would have thought that, globally, the IT industry produces about the same volume of greenhouse gases as the world’s airlines do—roughly 2 percent of all CO2 emissions? Many everyday tasks take a surprising toll on the environment. A Google search can leak between 0.2 and 7.0 grams of CO2, depending on how many attempts are needed to get the “right” answer. To deliver results to its users quickly, then, Google has to maintain vast data centres around the world, packed with powerful computers. While producing large quantities of CO2, these computers emit a great deal of heat, so the centres need to be well air-conditioned, which uses even more energy. However, Google and other big tech providers monitor their efficiency closely and make improvements. Monitoring is the first step on the road to reduction, but there is much more to be done, and not just by big companies.

考题 Text 4 The great recession may be over,but this era of high joblessness is probably beginning.Before it ends,it will likely change the life course and character of a generation of young adults.And ultimately,it is likely to reshape our politics,our culture,and the character of our society for years.No one tries harder than the jobless to find silver linings in this national economic disaster.Many said that unemployment,while extremely painful,had improved them in some ways:they had become less materialistic and more financially prudent;they were more aware of the struggles of others.In limited respects,perhaps the recession will leave society better off.At the very least,it has awoken us from our national fever dream of easy riches and bigger houses,and put a necessary end to an era of reckless personal spending.But for the most part,these benefits seem thin,uncertain,and far off.In The Moral Consequences of Economic Growth,the economic historian Benjamin Friedman argues that both inside and outside the U．S.,lengthy periods of economic stagnation or decline have almost always left society more meanspirited and less inclusive,and have usually stopped or reversed the advance of rights and freedoms.Antiimmigrant sentiment typically increases,as does conflict between races and classes.Income inequality usually falls during a recession,but it has not shrunk in this one.Indeed,this period of economic weakness may reinforce class divides,and decrease opportunities to cross them—especially for young people.The research of Till Von Wachter,the economic at Columbia University,suggests that not all people graduating into a recession see their life chances dimmed:those with degrees from elite universities catch up fairly quickly to where they otherwise would have been if they had graduated in better times;it is the masses beneath them that are left behind.In the Internet age,it is particularly easy to see the resentment that has always been hidden within American society.More difficult,in the moment,is discerning precisely how these lean times are affecting society's character.In many respects,the U.S.was more socially tolerant entering this recession than at any time in its history,and a variety of national polls on social conflict since then have shown mixed results.We will have to wait and see exactly how these hard times will reshape our social fabric.But they certainly will reshape it,and all the more so the longer they extend. Benjamin Friedman believes that economic recessions may____A.impose a heavier burden on immigrants B.bring out more evils of human nature C.promote the advance of rights and freedoms D.ease conflicts between races and classes

考题资料：Up to 80 per cent of the world’s middle classes will live in developing countries by 2030 thanks to surprising recent gains in poverty reduction, according to a United Nations report published on Thursday. “Never in history have the living conditions and prospects of so many people changed so dramatically and so fast.” concludes the UN’s latest Development Report. “The world is witnessing an epochal ‘global rebalancing’.” Underpinning the improvements in the human development index（HDI） was rapid growth in countries such as China, India and Brazil, with China and India having doubled per capita economic output in less than 20 years. But the study stressed that growth and improvements in HDI spread far beyond the four Bric countries of Brazil, Russia, India and China, and included at least 40 countries that had accompanied greater economic dynamism with effective poverty-reduction policies. Afghanistan, Sierra Leone, Ethiopia, Rwanda and Angola were among 14 countries that have recorded gains in HDI of more than 2 per cent a year since 2000. Partly as a result, the report found that worldwide extreme income poverty has plunged from 43 per cent in 1990 to just 22 per cent in 2008, including more than 500m being lifted out of poverty in China alone. The report stated that such gains had already helped the world achieve the main poverty eradication goal of the so-called Millennium Development Goals, which called for the share of people living on less than $1.25 a day to be cut by half from 1990 to 2015. Underpinning this poverty reduction was developing countries’ increasing share of global trade, which grew from 25 per cent to 47 per cent between 1980 and 2010. “The south as a whole is driving global economic growth and societal change for the first time in centuries,” says the report. The report found that trade among developing countries was the biggest factor in that expansion, increasing from less than 10 per cent of total global trade to more than 30 per cent. “Trade between countries in the south will overtake that between developed nations,” the report said. “More than 500m being lifted out of poverty in China alone” illustrates ______.A.the economic development of China is important B.the role of some developing countries is significant for poverty reduction C.14 countries are developing faster than China D.it is crucial to make a clear goal first

考题问答题Practice 1　　The agricultural sciences deal with the challenges of food and fiber production and processing. They include the technologies of soil cultivation, crop cultivation and harvesting, animal husbandry and the processing of plant and animal products for human consumption and use. As a result of the doubled yields of some economic crops, the farm output per hour of farm work increased almost 10-fold as capital was substituted for labor. New techniques of preserving food products made possible transportation over greater distances, in turn facilitating adjustments among locations of production and consumption, with further benefits to production efficiency.

考题问答题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. The rise of the nation-state is an example of the political aspect of globalization, although it is argued that advances in telecommunications and information systems and the resulting constructions of institutions that transience territorial boundaries are making the nation-state obsolete.

考题问答题Resource efficiency means reducing the environmental impact of the consumption and production of goods and services. The doing more with less slogan indicates the focus on more outputs with fewer impacts. Efficiency gains do not guarantee that the overall outcome stays within the ecological carrying capacity of the Earth. Influencing the demand side is therefore another prerequisite for sustainable development.It is indeed timely to recognize that the world cannot achieve sustainable, economic growth with old fashioned consumption and production patterns. Companies will have to accelerate the trends of polluting less and of designing, producing and marketing better products and services. Consumers have to get used to the fact that environmental concerns are as important in their daily choices as considerations of price, convenience and quality. And governments and civil society have a key role to play in inspiring such a process.
