单选题 Saudi Arabia, the oil industry's swing producer, has become its flip-flopper. In February, it persuaded OPEC to cut its total production quotas by lm barrels per day (bpd), to 23.5m, as a precaution against an oil-price crash this spring. That fear has since been replaced by its opposite. The price of West Texas crude hit $40 last week, its highest since the eve of the first Iraq war, prompting concerns that higher oil prices could sap the vigour of America's recovery and compound the frailty of Europe's. On Monday May 10th, Ali al-Naimi, Saudi Arabia's energy minister, called on OPEC to raise quotas, by at least 1.5m bpd, at its next meeting on June 3rd. Thus far, the high oil price has been largely a consequence of good things, such as a strengthening world economy, rather than a cause of bad things, such as faster inflation or slower growth. China's burgeoning economy guzzled about 6m bpd in the first quarter of this year, 15% more than a year ago, according to Goldman Sachs. Demand was also strong in the rest of Asia, excluding Japan, growing by 5.2% to 8.1 m bpd. As the year progresses, the seasonal rhythms of America's drivers will dictate prices, at least of the lighter, sweeter crudes. Americans take to the roads en masse in the summer, and speculators are driving up the oil price now in anticipation of peak demand in a few months' time. Until recently, the rise in the dollar price of oil was offset outside America and China by the fall in the dollar itself. But the currency has regained some ground in recent weeks, and the oil price has continued to rise. Even so, talk of another oil-price shock is premature. The price of oil, adjusted for inflation, is only half what it was in December 1979, and the United States now uses half as much energy per dollar of output as it did in the early 1970s. But if oil cannot shock the world economy quite as it used to, it can still give it "a good kick", warns Goldman Sachs. If average oil prices for the year come in 10% higher than it forecast, it reckons GDP growth in the Group of Seven (G7) rich nations will be reduced by 0.3%, or $70 billion. The Americans are certainly taking the issue seriously. John Snow, their treasury secretary, called OPEC's February decision "regrettable", and the rise in prices since then "not helpful". Washington pays close heed to the man at the petrol pump, who has seen the average price of a gallon of unleaded petrol rise by 39 cents in the past year. And the Saudis, some mutter, pay close heed to Washington. Besides, the high oil price may have filled Saudi coffers, but it has also affronted Saudi pride. Mr Ali al-Naimi thinks the high price is due to fears that supply might he disrupted in the future. These fears, he says, are "unwarranted". But the hulking machinery in the Arabian desert that keeps oil flowing round the world presents an inviting target to terrorists should they tire of bombing embassies and nightclubs. On May 1st, gunmen killed six people in a Saudi office of ABB Lummus Global, an American oil contractor. Such incidents add to the risk premium factored into the oil price, a premium that the Saudis take as a vote of no confidence in their kingdom and its ability to guarantee the supply of oil in the face of terrorist threats.

单选题{{B}}TEXT D{{/B}} Research into DNA has had a significant impact on medicine. Through recombinant DNA technology, scientists can modify microorganisms so that they become so-called factories that produce large quantities of medically useful drugs. This technology is used to produce insulin, which is a drug used by diabetics, and interferon, which is used by some cancer patients. Studies of human DNA are revealing genes that are associated with specific diseases, such as breast cancer. This information is helping physicians to diagnose various diseases, and it may lead to new treatments. For example, physicians are using a technology called chimeriplasty, which involves a synthetic molecule containing both DNA and RNA strands, in an effort to develop a treatment for a form of hemophilia. Forensic science uses techniques developed in DNA research to identify individuals who have committed crimes. DNA from semen, skin, or blood taken from the crime scene can be compared with the DNA of a suspect, and the results can be used in court as evidence. DNA has helped taxonomists determine evolutionary relationships among animals, plants, and other life forms. It is useful for this purpose, because closely related species have more similar DNA than do species that are distantly related. One surprising finding to emerge from DNA studies is that vultures of the Americas are more closely related to storks than to the vultures of Europe, Asia, or Africa. Techniques of DNA manipulation are used in farming, in the form of genetic engineering and biotechnology. Strains of crop plants to which genes have been transferred may produce higher yields and may be more resistant to insects. Cattle have been similarly treated to increase milk and beef production, as have hogs, to yield more meat and less fat. Despite the many benefits offered by DNA technology, some critics argue that its development should be monitored closely. One fear raised by such critics is that DNA fingerprinting could provide a means for employers to discriminate against members of various ethnic groups. Critics also fear that studies of people' s DNA could permit insurance companies to deny health insurance to those people at risk for developing certain diseases. The use of DNA technology in agriculture has also sparked controversy. Some people question the safety, desirability, and ecological impact of genetically altered crop plants. In addition, animal rights groups have protested against the genetic engineering of farm animals. Despite these and other areas of disagreement, many people agree that DNA technology offers a mixture of benefits and potential hazards. Many experts also agree that an informed public can help assure that DNA technology is used wisely.

单选题 "The landscape seen from our windows is certainly charming, "said Annabel; "those cherry orchards and green meadows, and the river winding along the valley, and the church tower peeping out among the elms, they all make a most effective picture. There's something dreadfully sleepy and languorous about it, though; stagnation seems to be the dominant note. Nothing ever happens here; seedtime and harvest, an occasional outbreak of measles or a mildly destructive thunderstorm, and a little election excitement about once in five years, that is all that we have to modify the monotony of our existence. Rather dreadful, isn't it?" "On the contrary, "said Matitda, "I find it soothing and restful; but then, you see, I've lived in countries where things do happen, ever so many at a time, when you're not ready for them happening all at once. ""That, of course, makes a difference, "said Annabel. "I have never forgotten, "said Matilda, "the occasion when the Bishop of Bequar paid us an unexpected visit; he was on his way to lay the foundation-stone of a mission-house or something of the sort. ""I thought that out there you were always prepared for emergency guests turning up, "said Annabel. "I was quite prepared for half a dozen Bishops, "said Matilda, "but it was rather disconcerting to find out after a little conversation that this particular one was a distant cousin of mine, belonging to a branch of the family that had quarreled bitterly and offensively with our branch about a Crown Derby dessert service; they got it, and we ought to have got it, in some legacy, or else we got it and they thought they ought to have it, I forget which; anyhow, I know they behaved disgracefully." "It was rather trying, but you could have left your husband to do most of the entertaining. ""My husband was fifty miles up-country, talking sense, or what he imagined to be sense, to a village community that fancied one of their leading men was a were-tiger." "A what tiger ?" "A were-tiger; you've heard of were-wolves, haven't you, a mixture of wolf and human being and demon? Well, in those parts they have were-tigers, or think they have, and I must say that in this case, so far as sworn, and uncontested evidence went, they had every ground for thinking so. However, as we gave up witchcraft prosecutions about three hundred years ago, we don't like to have other people keeping on our discarded practices; it doesn't seem respectful to our mental and moral position." "I hope you weren't unkind to the Bishop, "said Annabel. "Well, of course he was my guest, so I had to be outwardly polite to him, but he was tactless enough to rake up the incidents of the old quarrel, and to try to make out that there was something to be said for the way his side of the family had behaved; even if there was, which I don't for a moment admit, my house was not the place in which to say it. I didn't argue the matter, but I gave my cook a holiday to go and visit his aged parents some ninety miles away. The emergency cook was not a specialist in curries, in fact, I don't think cooking in any shape or form could have been one of his strong points. I believe he originally came to us in the guise of a gardener, but as we never pretended to have anything that could be considered a garden he was utilised as assistant goatherd, in which capacity, I understand, he gave every satisfaction. When the Bishop heard that I had sent away the cook on a special and unnecessary holiday he saw the inwardness of the manoeuvre, and from that moment we were scarcely on speaking terms. If you have ever had a Bishop with whom you were not on speaking terms staying in your house, you will appreciate the situation." Annabel confessed that her life-story had never included such a disturbing experience.
