单选题Mr. And Mrs. Smith had always spent their summer holidays in New Jersey in the past, staying in a small inn at the foot of a hill. One year, however, Mr. Smith made a lot of money in his business, so they decided to go to London and stay at a really good hotel while they went touring around that famous city. They flew to London and arrived at their hotel late one evening. They expected that they would have to go to bed hungry, because in that small inn in New Jersey no meals were served after seven. They were therefore surprised when the man who received them in the hall asked whether they would ask dinner there that night. "Are you still serving dinner?" asked Mr. Smith. "Yes, certainly, sir," answered the man. "We serve it until half past nine." "What are the times of meals then?" asked Mr. Smith. "Well, Sir," answered the man, "We serve breakfast from seven to half past eleven in the morning, lunch from twelve to three in the afternoon, tea from four to five and dinner, from six to half past nine." "But that hardly leaves any time for us to see the sights of London." Said Mrs. Smith.

单选题 The planet is getting lusher, and we are responsible. Carbon dioxide generated by human activity is stimulating photosynthesis (光合作用) and causing a beneficial greening of the Earth's surface. For the first time, researchers claim to have shown that the increase in plant cover is due to this 'CO2 fertilization effect' rather than other causes. However, it remains unclear whether the effect can counter any negative consequences of global warming, such as the spread of deserts. Recent satellite studies have shown that the planet is harboring more vegetation overall, but pinning down the cause has been difficult. Factors such as higher temperatures, extra rainfall, and an increase in atmospheric CO2—which helps plants use water more efficiently—could all be boosting vegetation. To home in on the effect of CO2, Randall Donohue of Australia's national research institute, the CSIRO in Canberra, monitored vegetation at the edges of deserts in Australia, southern Africa, the US Southwest, North Africa, the Middle East and central Asia. These are regions where there is ample warmth and sunlight, but only just enough rainfall for vegetation to grow, so any change in plant cover must be the result of a change in rainfall patterns or CO2 levels, or both. If CO2 levels were constant, then the amount of vegetation per unit of rainfall ought to be constant, too. However, the team found that this figure rose by 11 per cent in these areas between 1982 and 2010, mirroring the rise in CO2 (Geophysical Research Letters, doi. org/mqx). Donohue says this lends 'strong support' to the idea that CO2 fertilization drove the greening. Climate change studies have predicted that many dry areas will get drier and that some deserts will expand. Donohue's findings make this less certain. However, the greening effect may not apply to the world's driest regions. Beth Newingham of the University of Idaho, Moscow, recently published the result of a 10-year experiment involving a greenhouse set up in the Mojave Desert of Nevada. She found 'no sustained increase in biomass' when extra CO2 was pumped into the greenhouse. 'You cannot assume that all these deserts respond the same,' she says. 'Enough water needs to be present for the plants to respond at all.'

单选题Ask any employee at an level in any company what they dislike about their job and somewhere on the list you will find a complaint about the system of performance appraisals. It does seem strange that an idea which was supposed to benefit both individuals and the company should be so universally disliked, but the staff appraisal is now one of the biggest causes of dissatisfaction at work. In the United States there have even been cases of unhappy workers taking their employers to court over appraisal interviews. It is in a company's interest to combat this situation, but, before reversing the appraisal's negative associations, an organization needs to pinpoint the underlying reasons which have contributed to them. Problems with appraisals can fall into two main areas--those arising from the scheme itself and those arising from the implementation and understanding of that scheme. Naturally it is easier to tackle those in the former category; indeed, some companies have developed schemes following legal guidelines. These guidelines suggest that a successful scheme should have a clear appeal process, that any negative feedback should be accompanied by "evidence" such as dates, times and outcomes and that, most importantly, ratings should reflect specific measurable elements of the job requirements. It is not always necessary to resort to legal advice however. Some changes to current schemes are simply a matter of logic. For instance, if employees are constantly encouraged to work in teams and to assume joint responsibility for their successes and failures, it makes little sense for the appraisals to focus on individuals, as this may lead to resentments and create divisions within the group. It is possible, and in some cases more suitable, to arrange appraisals where performance is rated for the group. Staff also need to be educated about the best way to approach appraisals. Managers often find that they are uncomfortable being asked to take on a more supportive role than they are used to without having had any training. Those being appraised may see it as a chance to air their grievances and highlight the company's failings rather than consider their own role. Both parties view the process as a necessary evil, to be gone through once or twice a year, and then forgotten about. The importance given to the appraisal stems from the fact that, despite all the talk of the interview being a chance for management and employees to come together and exchange ideas, set joint targets and improve the way decisions are reached, the reality is that they are often nothing more than the pretext on which pay rises are given, or not given. Pay is, of course, a subject that always leads to problems. Given the problems associated with staff appraisals, why is it that, with no legal requirement, companies continue to run them? The answer is simple, it is impossible to manage something you know nothing about. As any Human Resources manager can tell you, the best way to learn about someone is to talk to them. Effective people management relies on knowledge and appraisals are still the best way to build up that bank of knowledge.

单选题 Amitai Etzioni is not surprised by the latest headings about scheming corporate crooks(骗子). As a visiting professor at the Harvard Business School in 1989, he ended his work there disgusted with his students' overwhelming lust for money. 'They're taught that profit is all that matters,' he says. 'Many schools don't even offer ethics (伦理学) courses at all.' Etzioni expressed his frustration about the interests of his graduate students. 'By and large, I clearly had not found a way to help classes full of MBAs see that there is more to life than money, power, fame and self-interest,' he wrote at the time. Today he still takes the blame for not educating these 'business-leaders-to-be.' 'I really feel like I failed them,' he says. 'If I was a better teacher maybe I could have reached them.' Etzioni was a respected ethics expert when he arrived at Harvard. He hoped his work at the university would give him insight into how questions of morality could he applied to places where serf-interest flourished. What he found wasn't encouraging. Those would-be executives had, says Etzioni, little interest in concepts of ethics and morality in the boardroom—and their professor was met with blank stares when he urged his students to see business in new and different ways. Etzioni sees the experience at Harvard as an eye-opening one and says there's much about business schools that he'd like to change. 'A lot of the faculty teaching business are bad news them-selves.' Etzioni says. From offering classes that teach students how to legally manipulate contracts, to reinforcing the notion of profit over community interests, Etzioni has seen a lot that's left him shaking his head. And because of what he's seen taught in business schools, he's not surprised by the latest rash of corporate scandals. 'In many ways things have got a lot worse at business schools, I suspect,' says Etzioni. Etzioni is still teaching the sociology of right and wrong and still calling for ethical business leadership. 'People with poor motives will always exist,' he says. 'Sometimes environments con-strain those people and sometimes environments give those people opportunity. 'Etzioni says the booming economy of the last decade enabled those individuals with poor motives to get rich before getting in trouble. His hope now: that the cries for reform will provide more fertile soil for his long-standing messages about business ethics.
