单选题Society can be broken up into three classes: the Elite, the Meek and the Masses.

The Meek are comprised of the bottom 10% of society, those who need our help, and badly at that. But (55) so many of us are eager to get in well with the Elite, few actually care enough to provide any (56) to the Meek. The Masses are the largest class, (57) up the middle 80% between the Meek and the Elite. Most of the Masses could use some help getting by, and (58) it would usually improve their lives considerably, but they (59) get it. Why do most people would rather help the Meek or the Elite?

单选题Remember global warming? Back in December, the threat of climate change was thundering, and the rich countries agreed to cut their carbon-dioxide and other green-house-related emissions. Since then, interest has cooled markedly, and many European countries are already running away from the promises they made so loudly a few months ago. But there has been much talk, and a bit of action, to encourage renewable (可更新的) energies such as wind, hydro, solar and all living organisms. These emit no greenhouse gases, but tend to cost more than coal, oil or gas. The better, simpler idea is to remember that the easiest way to reduce something is to tax it—in this case, by taxing the carbon content of power. The dirtier the power, the more tax it would pay. So dirty coal would be more expensive than clean coal, which would see its price rise in relation to oil, which would be even more expensive compared to gas, which would lose some of its price advantage over renewables. Unless a carbon tax was so huge as to be economically crippling, it would not remove the price differential (差别) between all renewables and fossil fuels. But it would narrow that gap, by fixing the differing environmental costs into the price—a useful principle in itself. It would also give renewable producers a strong incentive to cut costs, and fossil-fuel suppliers an motivation to clean their products. Precedents suggest strongly that a carbon tax would be effective. But the disadvantage to carbon taxes is political. After almost a decade of trying, the European Union gave up an attempt at a European carbon tax last year. Germany's ruling coalition is fighting against a proposed energy tax. In America, politicians believe that even mentioning the notion is certain death. But many of the political objections could be met if a carbon tax were made up for the loss elsewhere, for example by lowering payroll or sales taxes. There is always suspicion when governments come up with clever new ways to tax, and rightly so. The response to that suspicion should be to win the argument, not to abandon it.

单选题Directions: There are 4 passages in this part. Each of the passage is followed by 5 questions or unfinished statements. For each of them there are 4 choices marked A, B, C and D. Choose the best one and mark your answer on the ANSWER SHEET with a single line through the center.{{B}}Passage One{{/B}} Do you find getting up in the morning so difficult that it's painful? This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle. During the hours when you labor through your work may say that you are hot. That's true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak. For some people the peak comes during the forenoon. For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar monologues as: "Get up, John! You'll be late for work again. " The possible explanation to the trouble is that John is at his temperature and energy peak in the evening. Much family quarreling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has. You can't change your energy cycle, but you can learn to make your life fit it better. Habit can help, Dr. Kleitman believes. Maybe you're sleepy in the evening but feel you must stay up late anyway. Counteract your cycle to some extent by habitually staying up later than you want to. ff your energy is low in the morning but you have an important job to do early in the day, rise before your usual hour. This won't change your cycle, but you'll get up steam and work better at your low point. Get off to a slow start which saves your energy: get up with a leisurely yawn and stretch; sit on the edge of the bed a minute before putting your feet on the floor; avoid the troublesome search for clean clothes by laying them out the night before. Whenever possible, do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours.
