单选题Do you remember all those years when scientists argued that smoking would kill us but the doubters insisted that we didn"t know for sure? That the evidence was inconclusive, the science uncertain? That the antismoking lobby was out to destroy our way of life and the government should stay out of the way? Lots of Americans bought that nonsense, and over three decades, some 10 million smokers went to early graves. There are upsetting parallels today, as scientists in one wave after another try to awaken us to the growing threat of global warming. The latest was a panel from the National Academy of Sciences, enlisted by the White House, to tell us that the Earth"s atmosphere is definitely warming and that the problem is largely man-made. The clear message is that we should get moving to protect ourselves. The president of the National Academy, Bruce Alberts, added this key point in the preface to the panel"s report "Science never has all the answers. But science does provide us with the best available guide to the future, and it is critical that our nation and the world base important policies on the best judgments that science can provide concerning the future consequences of present actions." Just as on smoking, voices now come from many quarters insisting that the science about global warming is incomplete, that it"s OK to keep pouring fumes into the air until we know for sure. This is a dangerous game: by the 100 percent of the evidence is in, it may be too late. With the risks obvious and growing, a prudent people would take out an insurance policy now. Fortunately, the White House is starting to pay attention. But it"s obvious that a majority of the president"s advisers still don"t take global warming seriously. Instead of a plan of action, they continue to press for more research-a classic case of "paralysis by analysis". To serve as responsible stewards of the planet, we must press forward on deeper atmospheric and oceanic research but research alone is inadequate. If the Administration won"t take the legislative initiative, Congress should help to begin fashioning conservation measures. A bill by Democratic Senator Robert Byrd of West Virginia, which would offer financial incentives for private industry, is a promising start. Many see that the country is getting ready to build lots of new power plants to meet our energy needs. If we are ever going to protect the atmosphere, it is crucial that those new plants be environmentally sound.

单选题A report consistently brought back by visitors to the U.S. is how friendly, courteous, and helpful most Americans were to them. To be fair, this observation is also frequently made of Canada and Canadians, and should best be considered North American. There are, of course, exceptions. Small minded officials, rude waiters, and ill mannered taxi drivers are hardly unknown in the U.S.. Yet it is an observation made so frequently that it deserves comment. For a long period of time and in many parts of the country, a traveler was a welcome break in an otherwise dull existence. Dullness and loneliness were common problems of the families who generally lived distant from one another. Strangers and travelers were welcome sources of diversion, and brought news of the outside world. The harsh realities of the frontier also shaped this tradition of hospitality. Someone traveling alone, if hungry, injured, or ill, often had nowhere to turn except to the nearest cabin or settlement. It was not a matter of choice for the traveler or merely a charitable impulse on the part of the settlers. It reflected the harshness of daily life: if you didn't take in the stranger and take care of him, there was no one else who would, and someday, remember, you might be in the same situation. Today there are many charitable organizations which specialize in helping the weary traveler. Yet, the old tradition of hospitality to strangers is still very strong in the U.S., especially in the smaller cities and towns away from the busy tourist trails. "I was just traveling through, got talking with this American, and pretty soon he invited me home for dinner—amazing." Such observations reported by visitors to the U.S. are not uncommon, but are not always understood properly. The casual friendliness of many Americans should be interpreted neither as superficial nor as artificial, but as the result of a historically developed cultural tradition. As is true of any developed society, in America a complex set of cultural signals, assumptions, and conventions underlies all social interrelationships. And, of course, speaking a language does not necessarily meant that someone understands social and cultural patterns. Visitors who fail to "translate" cultural meanings properly often draw wrong conclusions. For example, when an American uses the word "friend", the cultural implications of the word may be quite different from those it has in the visitor's language and culture. It takes more than a brief encounter on a bus to distinguish between courteous convention and individual interest. Yet, being friendly is a virtue that many American value highly and expect from both neighbors and strangers.

单选题There is a new type of small advertisement becoming increasingly common in newspaper classified columns. It is sometimes placed among "situations vacant", although it does not offer anyone a job; and sometimes it appears among "situations wanted", although it is not placed by someone looking for a job either. What it does is to offer help in applying for a job. "Contact us before writing application", or "Make use of our long experience in preparing your curriculum vitae, or job history", is how it is usually expressed. The growth and apparent success of such a specialized service is, of course, a reflection on the current high levels of unemployment. It is also an indication of growing importance of the curriculum vitae (or job history), with the suggestion that it may now qualify as an art form in its own right. There was a time when job seekers simply wrote letters of application. "Just put down your name, address, age and whether you have passed any exams", was about the average level of advice offered to young people applying for their first jobs when I left school. The letter was really just for openers, it was explained. Everything else could and should be saved for the interview. And in those days of full employment the technique worked. The letter proved that you could write and were available for work. Your eager face and intelligent replies did the rest. Later, as you moved up the ladder, something slightly more sophisticated was called for. The advice then was to put something in the letter which would distinguish you from the rest, It might be the aggressive approach. "Your search is over. I am the person you are looking for," was a widely used trick that occasionally succeeded. Or it might be some special feature specially designed for the job in view. There is no doubt, however, that it is the increasing number of applicants with university education at all points in the process of engaging staff that has led to the greater importance of the curriculum vitae.
