单选题The work on atmospheric chlorofiuorocarbons (氯氟化碳) led eventually to a global CFC ban that saved us from ozone-layer reduction. Do we have time to do a similar thing with carbon emissions to save ourselves from climate change? Not a hope at all. Most of the "green" stuff is very close to a big trick. Carbon trading, with its huge government grants, is just what finance and industry wanted. It's not going to do a thing about climate change, but it'll make a lot of money for a lot of people and postpone the moment of reckoning. I am not against renewable energy, but to spoil all the decent countryside in the UK with wind farms is driving me mad. It's absolutely unnecessary, and it takes 2,500 square kilometers to produce a gigawatt (十亿瓦特)—that's an awful lot of countryside. Work to sequester (隔离) CO2 (carbon dioxide) is also a waste of time. It's a crazyidea—and dangerous. It would take so long and use so much energy that it will not bedone. And, nuclear power is a way for the UK to solve its energy problems, but it is not aglobal cure for climate change. It is too late for emissions reduction measures. Yet we are not doomed. There is one way we could save ourselves and that is through the massive burial of charcoal (木炭) . It would mean farmers turning all their agricultural waste—which contains carbon that the plants have spent the summer sequestering—into charcoal, and burying it in the soil. Then you can start shifting vast quantities of carbon out of the system and pull the CO2 down quite fast. What we can do is getting farmers to bum their crop waste at very low oxygen levels to turn it into charcoal, which the farmer then ploughs into the field. A little CO2 is released but the bulk of it gets converted to carbon. You get a few per cent of bio-fuel as an additional product of the burning process, which the farmer can sell. This scheme would need no subsidy (补贴) : the farmer would make a profit. This is the one thing we can do that will make a difference.

单选题Questions 62 to 66 are based on the following passage. The better defined your hiring process is, the more easily it will be adhered to. I suggest that you use a multi-stage interviewing process by which the candidate meets with multiple people to provide different opinions and input on the hiring-decision. Again, keep all notes taken during the interview. These notes should be factual and should detail observations made by the people conducting the interview as well as quotations of the candidate's responses to questions. There should be no inferences made about a candidate in any notes, and no notes should betaken on a, resume (简历). Pre-determine three to six questions that will help you uncover the capability of each applicant and ask those same questions to each person that is interviewed. These initial questions will serve as a departure point to base other follow-up questions on. By using the same question in different ways and you will also be able to draw close comparisons between each candidate's responses, which will help you determine the best match for the position. Developing that interviewing process a little further, time limits should be set on responses to candidates. Today's job market changes so rapidly that waiting more than 72 hours to inform a candidate how he or she did in an interview is an eternity (永远). Many candidates have multiple interviews within one or two days and plan to take the first job offered that meets their salary and benefit demands. Hired or not, as a candidate, it is much easier to keep a positive frame of mind about a company that is responsive, shows an interest in your success as an individual, and provides feedback (反馈) about an interview within one or two days. Waiting to make a decision about candidates is how other companies manage to hire the "perfect fit" right out from under you!
