18、rkers, where the most common 1 range from bad-mouthing (说的坏话) another worker to kissing a colleague and drinking too much, according to a study 2 on Tuesday. Most workers attend so-called happy hours to 3 with colleagues, although 15 percent go to hear the latest office gossip and 13 percent go beca

19、use they feel obligated, said the survey conducted for CareerB, an online job site. As to what happens when the after-work drinks flow, 16 percent reported bad-mouthing a colleague, 10 percent shared a secret about a colleague, 8 percent kissed a colleague and 8 percent said they drank too much and

20、acted 4 . 5 percent said they had shared a secret about the company, and 4 percent 5 to singing karaoke. While 21 percent of those who attend say happy hours are good for 6 , 85 percent said attending had not helped them get 7 to someone higher up or get a better position. An equal number of men and

Th

23、e enrichment of previously poor countries is the most inspiring development of our time. It is also worrying. The environment is already under strain. What will happen when the global population rises from 7 billion today to 9.3 billion in 2050, as demographers (人口统计学家) expect, and a growing proport

24、ion of these people can afford goods that were once reserved for the elite? Can the planet support so much economic activity? B. Many policymakers adopt a top-down and Western-centric approach to such planetary problems. They discuss ambitious regulations in global forums, or look to giant multinati

25、onals and well-heeled (富有的) NGOs to set an example. But since most people live in the emerging world, it makes sense to look at what successful companies there are doing to make growth more sustainable. C. A new study by the World Economic Forum (WEF) and the Boston Consulting Group (BCG) identifies

26、 16 emerging-market firms that they say are turning eco-consciousness into a source of competitive advantage. These highly profitable companies (which the study calls “the new sustainability champions“) are using greenery to reduce costs, motivate workers and forge relationships. Their home-grown id

27、eas will probably be easier for their peers to copy than anything cooked up in the West. D. The most outstanding quality of these companies is that they turn limitations (of resources, labor and infrastructure) into opportunities. Thus, India“s Shree Cement, which has long suffered from water shorta

28、ges, developed the world“s most water-efficient method for making cement, in part by using air-cooling rather than water-cooling. Manila Water, a utility in the Philippines, reduced the amount of water it was losing, through wastage and illegal tapping, from 63% in 1997 to 12% in 2010 by making wate

29、r affordable for the poor. Broad Group, a Chinese maker of air conditioners, taps the waste heat from buildings to power its machines. Zhangzidao Fishery Group, a Chinese aquaculture (水产养殖) company, recycles uneaten fish feed to fertilize crops. E. Setting green goals is a common practice. Sekem, an

30、 Egyptian food producer, set itself the task of reclaiming (开垦) desert land through organic farming. Florida Ice & Farm, a Costa Rican food and drink company, has adopted strict standards for the amount of water it can consume in producing drinks. F. These firms measure themselves by their greenery,

31、 too. Florida Ice & Farm, for example, links 60% of its boss“s pay to the triple bottom line of “people, planet and profit“. The sustainability champions also encourage their workers to come up with green ideas. Natura, a Brazilian cosmetics company, gives bonuses to staff who find ways to reduce th

32、e firm“s impact on the environment. Masisa, a Chilean forestry company, invites employees to “imagine unimaginable businesses“ aimed at poorer consumers. Woolworths, a South African retailer, claims that many of its best green ideas have come from staff, not bosses. G. In emerging markets it is hard

33、 for companies to stick to one specialism, because they have to worry about so many wider problems, from humble infrastructure to unreliable supply chains. So the sustainability champions seek to shape the business environment in which they operate. They lobby (游说) regulators: Grupo Balbo, a Brazili

34、an organic-sugar producer, is working with the Brazilian government to establish a certification system for organic products. They form partnerships with governments and NGOs. Kenya“s Equity Bank has formed an alliance with groups such as The International Fund for Agricultural Development to reduce

35、 its risks when lending to smallholders. Natura has worked with its suppliers to produce sustainable packaging, including a new “green“ plastic derived from sugar cane. H. The firms also work hard to reach and educate poor consumers, often sacrificing short-term profits to create future markets. Mas

36、isa organizes local carpenters into networks and connects them to low-income furniture buyers. Broad Group has developed a miniature device for measuring air pollution that can fit into mobile phones. Jain Irrigation, an Indian maker of irrigation systems, uses dance and song to explain the benefits

37、 of drip irrigation to farmers who can“t read. Suntech, a Chinese solar-power company, has established a low-carbon museum to celebrate ways of reducing carbon-dioxide emissions. Rich because green, or green because rich? I. One could quibble (争辩) with BCG“s analysis. Phil Rosenzweig of Switzerland“

38、s IMD business school has argued that management writers are prone to “the halo effect“: they treat the temporary success of a company as proof that it has discovered some eternal principle of good management. The fact that some successful companies have embraced greenery does not prove that greener

39、y makes a firm successful. Some firms, having prospered, find they can afford to splurge (挥霍) on greenery. Some successful firms pursue greenery for public-relations purposes. And for every sustainable emerging champion, there are surely 100 firms that have prospered by belching (喷出) fumes into the

40、air or pumping toxins into rivers. J. Nonetheless, the central message of the WEF-BCG studythat some of the best emerging-world companies are combining profits with greeneryis thought-provoking. Many critics of environmentalism argue that it is a rich-world luxury: that the poor need adequate food b

41、efore they need super-clean air. Some even see greenery as a rich-world conspiracy (阴谋): the West grew rich by industrializing (and polluting ), but now wants to stop the rest of the world from following suit. The WEF-BCG report demonstrates that such fears are overblown. Emerging-world companies ca

42、n be just as green as their Western rivals. Many have found that, when natural resources are scarce and consumers are cash-strapped (资金短缺的), greenery can be a lucrative (利润丰厚的) business strategy.（分数：70.00）(1).An air-conditioner manufacturer uses the waste heat from buildings to supply its machines w

43、ith power.（分数：7.00）(2).Many critics of environmentalism hold the view that greenery is a rich-world luxury because that“s not what the poor people badly want.（分数：7.00）(3).Workers of the sustainability champions are motivated to bring forward green ideas.（分数：7.00）(4).It is meaningful to study what su

44、ccessful companies in the emerging world are doing to achieve more sustainable growth, since most people live there.（分数：7.00）(5).It“s difficult for companies in emerging markets to keep focusing on one specific problem because they have many wider problems to worry about.（分数：7.00）(6).Although some s

45、uccessful firms have embraced greenery, it doesn“t mean that greenery will lead to the success of a firm.（分数：7.00）(7).It will probably be easier for companies to follow the home-grown ideas than those invented in the West.（分数：7.00）(8).It has been found that greenery can be profitable when natural re

46、sources are scarce and consumers are short of cash.（分数：7.00）(9).Sekem, which produces food in Egypt, set a goal to reclaim desert land through organic farming.（分数：7.00）(10).To create future markets, the firms also make effort to reach and educate poor consumers, often at the cost of short-term profi

47、ts.（分数：7.00）十四、Section C(总题数：0，分数：0.00)十五、Passage One(总题数：1，分数：72.00)Educators today are more and more often heard to say that computer literacy is absolutely necessary for college students. Many even argue that each incoming freshman should have permanent access to his or her own microcomputer. Wha

48、t advantages do computers offer the college students? Any student who has used a word processor will know one compelling reason to use a computer: to write papers. Although not all students feel comfortable composing on a word processor, most find revising and editing much easier on it. One can alte

49、r, insert, or delete just by pressing a few keys, thus eliminating the need to rewrite or re-type. Furthermore, since the revision process is less burdensome, students are more likely to revise as often as is necessary to end up with the best paper possible. For these reasons, many freshman English courses require the use of a word processor. Computers are also useful in the context of language courses, where they are used to drill students in basic skills. Software programs r
