单选题{{B}}Text 1{{/B}} During the past fifteen years a great deal of attention has been given to "letting it all hang out." My impression is that this over-zealous devotion to speaking one's mind has more often led to hurt feelings and mined relationships than to great joy and fulfillment. I think we generally agree that holding in real feelings and never expressing less-than-lovely thoughts about each other hardly lead to constructive communication. It's a great relief to allow ourselves the luxury of admitting our human weaknesses and pursuing more honest relationships with others. But we need to strike a balance between telling it all and telling nothing. Recently I received a letter from a mother who had been persuaded by her troubled twenty-five-year-old son to attend a weekend "troth" marathon with him. Under pressure from the group, her defenses collapsed and she heard herself telling her son for the first time that he had been an accident—that she hadn't been planning to have a child. He in turn told her that he couldn't recall a single day in his childhood that he'd been happy. "At that time," this woman wrote, "it seemed helpful. We cried and we made up; I thought telling the truth had been good for us. But the trouble is, it wasn't the whole truth. By the time Tommy was born, I did want him, and at times he was happy. Ever since that day, we've both been disturbed by some terrible feelings we shared." I must admit we've come to the conclusion that some things are better left unsaid. Honesty is a fine policy as long as we know what the truth really is—but most of the time we don't. It's a fine goal to encourage children to express their real feelings. But we need a new sense of balance. Telling it all is not a cure-all for every problem nor even an end in itself. It's useful and freeing under some circumstances and terribly hurtful and damaging under others. It's a good idea, I think, to bite your tongue for ten or fifteen minutes before saying what's on your mind. Try to decide whether it's going to open up new and better avenues of communication or leave wounds that may never heal.

单选题Although one might not think so from some of the criticism of it, advertising is essential to the kind of society in which people in the United Kingdom, and a very considerable proportion of the world at large, live. Advertising is indispensable as a means of communicating with others, of telling them about the goods and services that are provided, and of which most of them would never get to hear at all if it were not. for advertising. And advertising is extremely helpful to promote a rising standard of living. In talking about advertising, one should not think only in terms of a commercial on television, or an advertisement in the newspapers or periodicals. In its widest sense, advertising includes a host of other activities such as packaging, shop displays and—in the sense of communication—even the spoken word of the salesman. After all, the resources of advertising are to be found in the market place. For many years it was considered that it was enough to produce goods and supply services. It is only more recently that it has become increasingly understood that the manufacture of goods is a waste of resources unless those goods can be sold at a fair price within a reasonable time span. In the competitive society in which we live, it is important that we go out and sell what we have, and advertising plays an important role in this aspect, whether selling at home or in export markets. About two percent of the UK gross national product is relied on advertising. But it must not be thought that this advertising tries to sell goods to consumers who do not want them. Certainly, advertising does try to attract the interest of the potential consumer, but if the article when purchased does not match up to the standards that the advertising suggests that it will, it is obviously exceedingly unlikely that the article will sell well.

单选题{{B}}Text 2{{/B}} For the first time in the scientific community, there is total agreement that the activity of humans is at least partly responsible for the rise of global temperature — specifically the emission of greenhouse gases like carbon dioxide, which is released by the burning of wood, coal and petroleum products. Reducing harmful emissions is just one area in which the United Nations Intergovernmental Panel is decidedly optimistic. For one thing, in the short term it might not prove that difficult. Efficiency improvements alone could cut energy needs by as much as 30 percent at virtually no extra cost and, in developed countries, emission reductions of up to 60 percent "are technically feasible". In the longer term, harmful emissions will be reduced as the world changes over to cheaper, less environmentally damaging energy sources. So, if it is economically and technically feasible to reduce harmful emissions, why is almost nothing being done? There are two main reasons. The first stems from the uncertainty about how hot the planet is going to get. The current estimate is extremely broad — between 0.8 and 3.5 degrees Celsius by 2100. If the former prediction is accurate, it may be that we can adapt to it without difficulty. If, on the other hand, the latter is closer to reality, a complete rethink of the world's energy supplies is already long overdue. This leads directly to the second problem — the time scale involved. It is difficult to get people to act when predictions may take between 50 and 100 years to materialize. For politicians, who face elections every half decade or so. preventative action against a future threat — the magnitude of which is still very uncertain — carries heavy political risks. Even if politicians in the developed world were to be forced into action, what of the developing world. which is economically dependent on fossil fuels? Should it reduce emissions, and suffer the consequences, because of mistakes made by the developed world? One suggestion is that developing countries be given allowances above the current emission standards. This would enable them to meet their industrialized needs and ultimately help them to finance environmentally sound technologies. This would seem the only realistic way of getting agreement from developing countries — a vital requirement because, if preventative action is going to work, you really do have to have everyone on board.
