单选题{{B}}Text 3{{/B}} Soon after his appointment as secretary-general of the United Nations in 1997, Kofi Annan lamented that he was being accused of failing to reform the world body in six weeks. "But what are you complaining about?" asked the Russian ambassador: "You've had more time than God." Ah, Mr. Annan quipped back, "but God had one big advantage. He worked alone without a General Assembly, a Security Council and [all] the committees." Recounting that anecdote to journalists in New York this week, Mr. Annan sought to explain why a draft declaration on UN reform and tackling world poverty, due to be endorsed by some 150 heads of state and government at a world summit in the city on September 14th- 16th, had turned into such a pale shadow of the proposals that he himself had put forward in March. "With 191 member states", he sighed, "it's not easy to get an agreement." Most countries put the blame on the United States, in the form of its abrasive new ambassador, John Bolton, for insisting at the end of August on hundreds of last minute amendments and a line-by-line renegotiation of a text most others had thought was almost settled. But a group of middle-income developing nations, including Pakistan, Cuba, Iran, Egypt, Syria and Venezuela, also came up with plenty of last-minute changes of their own. The risk of having no document at all, and thus nothing for the world's leaders to come to New York for, was averted only by marathon all-night and all-weekend talks. The 35-page final document is not wholly devoid of substance. It calls for the creation of a Peacebuilding Commission to supervise the reconstruction of countries after wars; the replacement of the discredited UN Commission on Human Rights by a supposedly tougher Human Rights Council; the recognition of a new "responsibility to protect" peoples from genocide and other atrocities when national authorities fail to take action, including, if necessary, by force; and an "early" reform of the Security Council. Although much pared down, all these proposals have at least survived. Others have not. Either they provod so contentious that they were omitted altogether, such as the sections on disarmament and non-proliferation and the International Criminal Court, or they were watered down to little more than empty platitudes. The important section on collective security and the use of force no longer even mentions the vexed issue of pre-emptive strikes; meanwhile the section on terrorism condemns it "in all its forms and manifestations, committed by whomever, wherever and for whatever purposes", but fails to provide the clear definition the Americans wanted. Both Mr. Annan and, more surprisingly, George Bush have nevertheless sought to put a good face on things, with Mr. Annan describing the summit document as "an important step forward" and Mr. Bush saying the UN had taken "the first steps" towards reform. Mr. Annan and Mr. Bolton are determined to go a lot further. It is now up to the General Assembly to flesh out the document's skeleton proposals and propose new ones. But its chances of success appear slim.

单选题A brand of cough syrup comes with a measuring cup attached so that customers can measure the proper dosage. A consultant has pointed out that this cup is unnecessary, since most customers have measuring cups at home. Since the cups increase the cost of packaging the cough syrup and reduce the total number of units that can be shipped in a standard package, the consultant advises that the company can increase its net revenue on this product (total revenue minus total costs) by selling the cough syrup without the measuring cups. Which of the following, if true, provides the strongest evidence that the company should not follow the consultant's advice? A. Studies have shown that customers who use cough syrup without a measuring cup frequently take either too little or too much of the medicine, rendering the dosage either ineffective or, in cases of overdose, dangerous. B. The company has included a measuring cup with each bottle of cough syrup for the last 18 years. C. Studies have shown that 85 percent of consumers possess at home either a measuring cup, a set of measuring spoons, or both. D. Many customers neglect to follow the recommended dosage of cough syrup even when the measuring cup is packaged along with the bottle of cough syrup. E. Shipping the cough syrup bottles without the measuring cups will provide a marginal improvement in the number of cough syrup bottles that can be shipped in a standard package.

单选题Years ago, Charlie, a highly respected orthopedist and a mentor of mine, found a lump in his stomach. He had a surgeon explore the area, and the diagnosis was pancreatic cancer. He went home the next day, closed his practice, and never set foot in a hospital again. He focused on spending time with family and feeling as good as possible. Several months later, he died at home. He got no chemotherapy, radiation, or surgical treatment. Medicare didn’t spend much on him. It's not a frequent topic of discussion, but doctors die, too. And they don't die like the rest of us. What's unusual about them is not how much treatment they get compared to most Americans, but how little. Of course, doctors don't want to die ; they want to live. But they know enough about modern medicine to know its limits. Almost all medical professionals have seen what we call "futile care" being performed on people. That's when doctors bring the cutting edge of technology to bear on a grievously ill person near the end of life. The patient will get cut open, perforated with tubes, hooked up to machines, and assaulted with drugs. I cannot count the number of times fellow physicians have told me, in words that vary only slightly, "Promise me if you find me like this that you' ll kill me. " How has it come to this—that doctors administer so much care that they wouldn't want for themselves? The simple, or not-so-simple, answer is this: patients, doctors, and the system. To see how patients play a role, imagine a scenario in which someone has lost consciousness and been admitted to an emergency room, and shocked and scared family members find themselves caught up in a maze of choices. When doctors ask if they want "everything" done, they answer yes. Then the nightmare begins. Feeding into the problem are unrealistic expectations of what doctors can accomplish. For example, many people think of CPR as a reliable lifesaver when, in fact, the results are usually poor. But of course it's not just patients making these things happen. Doctors play an enabling role, too. The trouble is that even doctors who hate to administer futile care must find a way to address the wishes of patients and families. Imagine, once again, the emergency room with those grieving family members. They do not know the doctor. Establishing trust and confidence under such circumstances is a very delicate thing. People are prepared to think the doctor is acting out of base motives, trying to save time, or money, or effort, especially if the doctor is advising against further treatment. It's easy to find fault with both doctors and patients in such stories, but in many ways all the parties are simply victims of a larger system that encourages excessive treatment. In some unfortunate cases, doctors use the fee-for-service model to do everything they can, no matter how pointless, to make money. More commonly, though, doctors are fearful of litgation and do whatever they're asked to avoid getting in trouble.

单选题"THE SERVANT"(1963) is one of those films that it is impossible to forget. The servant exploits his master"s weaknesses until he turns the tables: the story ends with the a cringing master ministering to a lordly servant. It is hard to watch it today without thinking of another awkward relationship—the one between business folk and their smartphones. Smart devices are sometimes empowering. They put a world of information at our fingertips. But for most people the servant has become the master. Not long ago only doctors were on call all the time. Now everybody is. Bosses think nothing of invading their employees" free time. Work invades the home far more than domestic chores invade the office. Hyper connectivity exaggerates the decline of certainty and the general cult of flexibility. Smartphones make it easier for managers to change their minds at the last moment. Employees find it ever harder to distinguish between "on-time" and "off-time"—and indeed between real work and make-work. None of this is good for business people"s marriages or mental health. It may be bad for business, too. When bosses change their minds at the last minute, it is hard to plan for the future. How can we reap the benefits of connectivity without becoming its slaves? One solution is digital dieting. Banning browsing before breakfast can reintroduce a small amount of civilization. Banning texting at weekends or, say, on Thursdays, can really show the iPhone who is boss. The problem with this approach is that it works only if you live on a desert island or at the bottom of a lake. Leslie Perlow of Harvard Business School argues that for most people the only way to break the 24/7 habit is to act collectively rather than individually. One of the world"s most hard-working organisations, the Boston Consulting Group, introduced rules about when people were expected to be offline, and encouraged them to work together to make this possible. Eventually it forced people to work more productively while reducing burnout. Ms Perlow"s advice should be taken seriously. The problem of hyper connectivity will only get worse, as smartphones become smarter and young digital natives take over the workforce. But ultimately it is up to companies to outsmart the smartphones by insisting that everyone turn them off from time to time.

单选题For more than six million American children, coming home after school means coming home to an empty house. They spend part of each day alone. They are called "latchkey children". They're children who look after themselves while their parents work. And their bad conditions have become a social problem. Lyne Brown was once the headmaster of an elementary school. She said, "A lot of kids had chains around their necks with keys attached.! was constantly telling them to put them inside shirts. There were so many keys, it never came to my mind what they meant. ",slowly, she learned they were house keys. Lyne learned of the impact working couples and single parents were having on their children. She found that Fear is the biggest problem faced by children at home alone. Many had nightmares and were worried about their own safety. The most common way latchkey children deal with their fears is by hiding. It might be in a shower stall, under a bed, in a closet. The second is TV. They'll often play it at high volume. It's hard to get statistics (情况，材料) on latchkey children. Most parents are slow to admit they leave their children alone.

单选题British scientists are preparing to launch trials of a radical new way to fight cancer, which kills tumours by infecting them with viruses like the common cold. If successful, virus therapy could eventually form a third pillar alongside radiotherapy and chemotherapy in the standard arsenal against cancer, while avoiding some of the debilitating side-effects. Leonard Seymour, a professor of gene therapy at Oxford University, who has been working on the virus therapy with colleagues in London and the US, will lead the trials later this year. Cancer Research UK said yesterday that it was excited by the potential of Prof. Seymour's pioneering techniques. One of the country's leading geneticists, Prof. Seymour has been working with viruses that kill cancer cells directly, while avoiding harm to healthy tissue. "In principle, you've got something which could be many times more effective than regular chemotherapy, " he said. Cancer-killing viruses exploit the fact that cancer cells suppress the body's local immune system. "If a cancer doesn't do that, the immune system wipes it out. If you can get a virus into a tumour, viruses find them a very good place to be because there's no immune system to stop them replicating. You can regard it as the cancer's Achilles' heel. " Only a small amount of the virus needs to get to the cancer. "They replicate, you get a million copies in each cell and the cell bursts and they infect the tumour cells adjacent and repeat the process, " said Prof. Seymour. Preliminary research on mice shows that the viruses work well on tumours resistant to standard cancer drugs. "It's an interesting possibility that they may have an advantage in killing drug-resistant tumours, which could be quite different to anything we've had before. " Researchers have known for some time that viruses can kill tumour cells and some aspects of the work have already been published in scientific journals. American scientists have previously injected viruses directly into tumours but this technique will not work if the cancer is inaccessible or has spread throughout the body. Prof. Seymour's innovative solution is to mask the virus from the body's immune system, effectively allowing the viruses to do what chemotherapy drugs do—spread through the blood and reach tumours wherever they are. The big hurdle has always been to find a way to deliver viruses to tumours via the bloodstream without the body's immune system destroying them on the way. "What we've done is make chemical modifications to the virus to put a polymer coat around it - it's a stealth virus when you inject it, " he said. After the stealth virus infects the tumour, it replicates, but the copies do not have the chemical modifications. If they escape from the tumour, the copies will be quickly recognised and mopped up by the body's immune system. The therapy would be especially useful for secondary cancers, called metastases, which sometimes spread around the body after the first tumour appears. "There's an awful statistic of patients in the west. . . with malignant cancers; 75% of them go on to die from metastases, " said Prof. Seymour. Two viruses are likely to be examined in the first clinical trials: adenovirus, which normally causes a cold-like illness, and vaccinia, which causes cowpox and is also used in the vaccine against smallpox. For safety reasons, both will be disabled to make them less pathogenic in the trial, but Prof. Seymour said he eventually hopes to use natural viruses. The first trials will use uncoated adenovirus and vaccinia and will be delivered locally to liver tumours, in order to establish whether the treatment is safe in humans and what dose of virus will be needed. Several more years of trials will be needed, eventually also on the polymer-coated viruses, before the therapy can be considered for use in the NHS. Though the approach will be examined at first for cancers that do not respond to conventional treatments, Prof. Seymour hopes that one day it might be applied to all cancers.
