Representatives from China, India, Mexico, South Africa and Brazil have also been invited. Here's what the G8 leaders want from the meeting. British Prime Minister Tony Blair wants the G8 to cancel debt to the world's poorest countries. He wants them to double aid to Africa to 50 billion pounds by 2010. He has also proposed reducing subsidies to Western farmers and removing restrictions on African exports. This has not got the approval of all members because it will hurt their agricultural interests. On climate change, Blair wants concerted (共同的) action by reducing carbon emissions (排放). US President George W. Bush agrees to give help to Africa. But he says he doesn't like the idea of increasing aid to countries as it will increase corruption. Bush said he would not sign an agreement to cut greenhouse gas emissions at the summit, according to media. The US is the only G8 member not to have signed the Kyoto Protocol (京都议定书). Although the US is the world's biggest polluter, Bush so far refuses to believe there is sufficient scientific data to establish beyond a doubt that there is a problem. French President Jacques Chirac supports Blair on Africa and climate, change. He is determined to get the US to sign the climate change deal. German Chancellor Gerhard Schroder remains doubtful of Blair's Africa proposals. Schroder's officials have dismissed the notion that money will solve Africa's problems as "old thinking." Berlin says that African states should only receive extra money if they can prove they've solved the corruption problem. Russian President Vladimir Putin was doubtful about the value of more aid to Africa. But he has seen a way to make this work to his advantage. Putin intends to use the aid to Africa as a springboard (跳板) next year to propose aid to the former Soviet republics of Georgia, Uzbekistan, Tajikistan and Moldova. Japanese Prime Minister Junichiro Koizumi's priorities are a seat on the UN Security Council, for which he will be lobbying (游说) at the summit. And he's concerned about the Democratic People's Republic of Korea's nuclear weapons programme.

单选题 Animals' "Sixth Sense" A tsunami was triggered by an earthquake in the Indian Ocean in December, 2004. It killed tens of thousands of people in Asia and East Africa. Wild animals, {{U}} {{U}} 1 {{/U}} {{/U}}, seem to have escaped that terrible tsunami. This phenomenon adds weight to notions that they possess a "sixth sense" for {{U}} {{U}} 2 {{/U}} {{/U}}, experts said.

"No elephants are dead, not {{U}} {{U}} 4 {{/U}} {{/U}}a dead rabbit. I think animals can {{U}} {{U}} 5 {{/U}} {{/U}}disaster. They have a sixth sense. They know when things are happening," H.D.

"There has been a lot of {{U}} {{U}} 8 {{/U}} {{/U}}evidence about dogs barking or birds migrating before volcanic eruptions or earthquakes. But it has not been proven," said Matthew van Lierop, an animal behavior {{U}} {{U}} 9 {{/U}} {{/U}}at Johannesburg Zoo.

单选题Prolonging Human Life Prolonging human life has increased the size of the human population. Many people alive today would have died of childhood diseases if they had been born 100 years ago. Because more people live longer, there are more people around at any given time. In fact, it is a decrease in death rates, not an increase in birthrates that has led to the population explosion. Prolonging human life has also increased the dependency load. In all societies, people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering cultures, old people who could not keep up might be left behind to die. In times of famine, infants might be allowed to die because they could not survive if their parents starved, whereas if the parents survived they could have another child. In most contemporary societies, people feel a moral obligation to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work; we also have rules which require people to retire at a certain age. Unless these people were able to save money for their retirement, somebody else must support them. In the United States many retired people live on social security checks which are so little that they must live in near poverty. Older people have more illness than young or middle aged people, unless they have wealth or private or government insurance, they must often "go on welfare" if they have a serious illness. When older people become senile or too weak and ill to care for themselves, they create grave problems for their families. In the past and in some traditional cultures, they would be cared for at home until they died. Today, with most members of a household working or in school, there is often no one at home who can care for a sick or weak person. To meet this need, a great many nursing homes and convalescent hospitals have been built. These are often profit-making organizations, although some are sponsored by religious and other nonprofit groups. While a few of these institutions are good, most of them are simply "dumping grounds" for the dying in which "care" is given by poorly paid, overworked, and under-skilled personnel.

单选题London Cabbies (出租车司机) Every city in the world has taxis to take tourists to interesting places. London is the only city in the world where taking a taxi is an 1 experience for tourists. This is partly because of the special black cabs, which are found in no other country. But it is also because of the drivers themselves. 2 British people are famous for being polite and reserved, London cabbies are well-known 3 their willingness to talk. Some customers say that once the door shuts and the cab 4 off they are a captive (监禁了的) audience. It is impossible to get the taxi driver to stop 5 . "They"re self-confident and free thinking," said Malcolm Linskey, the author of a history of taxi drivers in London. They are also expensive. London has the most expensive taxis of any city in the world except Tokyo. That"s why Ken Livingstone, the Mayor of London, is planning to make taxi drivers negotiate their fares with 6 before they take a ride. Drivers agree that their fares are expensive. That"s because their black taxis 7 more than other cars, they say. And the customer is also paying for more driving expertise (专门知识) than anywhere else in the world. Before someone can qualify as a London taxi driver, that person has to pass a test 8 simply as "The Knowledge". This involves 9 the name and location of every street within six miles of a point in the exact centre of London. The trainee (受训者) must also learn the exact location of every important building within these streets. Finally he or she must be able to use this knowledge to work out the 10 distance between any two destinations within this area. It can 11 up to three years to pass "The Knowledge" Every day it is possible to see trainee taxi drivers on the streets of London, taking careful notes of popular destinations before tracing the route to their next stop. Cab driving is a job often 12 down in families. Many taxi drivers take their children out in their spare time to memorize 13 they need to know when it is their turn to do "The Knowledge". London cabbies also have bigger brains. Recent research found that the part of the brain that remembers things was larger and more 14 in cab drivers. They have to fit the whole of London into their heads, so their brains grow bigger. So perhaps it is not 15 that taxi drivers have lots to say.

单选题The Forbidden Apple New York used to be the city that never sleeps. These days it's the city that never smokes, drinks or does anything naughty(at least, not in public). The Big Apple is quickly turning into the Forbidden Apple. If you wanted a glass of wine with your picnic in Central Park, could you have one? No chance. Drinking alcohol in public isn't allowed. If you decided to feed the birds with the last crumbs(碎屑)of your sandwich, you could be arrested. It's illegal. If you went to a bar for a drink and a cigarette, that would be OK, wouldn't it? Er...no. You can't smoke in public in New York City. What's going on? Why is the city that used to be so open-minded becoming like this? The mayor of New York is behind it all. He has brought in a whole lot of new laws to stop citizens from doing what they want, when they want. The press are shocked. Even the New York police have joined the argument. They recently spent $ 100,000 on a "Don't blame the cop' campaign. One New York police officer said, "We raise money for the city by giving people fines for breaking some very stupid laws. It's all about money. " The result is a lot of fines for minor offences. Yoav Kashida, an Israeli tourist, fell asleep on the subway. When he woke up, wo police officers fined him because he had fallen asleep on two seats(you mustn't use two seats in the subway). Elle and Serge Schroitman were fined for blocking a driveway with their car. It was their own driveway. The angry editor of Vanity Fair magazine, Graydon Carter. says, "Under New York City law it is acceptable to keep a gun in your place of work, but not an empty ashtray. "He should know. The police came to his office and took away his ashtray(烟灰缸). But not all of New York's inhabitants are complaining. Marcia Dugarry, 72, said, "The city has changed for the better. If more cities had these laws, America would be a better place to live. "Nixon Patotkis, 38, a barman, said , "I like the new laws. If people smoked in here, we'd go home smelling of cigarettes. " Recent figures show that New York now has fewer crimes per 100,000 people than 193 other US cities. And it's true—it's safer, cleaner and more healthy than before. But let's be honest—who goes to New York for its clean streets?

单选题Air Pollution Cloud Measured on Both Sides of Pacific Scientists watched closely last spring as a haze of pollution, which had been tracked by satellite as it crossed the Pacific Ocean, settled over a large swath of North America from Calgary, Canada, into Arizona. Now it appears that, for the first time, researchers on both sides of the Pacific took detailed measurements of the same plume, a could that contained Gobi dessert dust as well as hydrocarbons (碳氢化合物) from industrial pollution. Heather Price, a University of Washington doctoral student in chemistry, found that the amount of light reflected by the particles in the air was more than 550 percent greater than normal for that time of year. The mass of Asian air contained elevated levels of all pollutants measured. Price said, "but the only thing that came close to being alarming was the level of particulate matter. " The haze that settled across the western part the the country was widely reported by the news media, and it was measured as far inland as the ski slopes of Aspen, Colo. Readings on the western side of the Pacific came from the Aerosol Characterization Experiments, a project aimed at understanding how particles in the atmosphere affect Earth's climate. Additional measurements were taken in the same region at the same time under a project sponsored by the National Aeronautics and Space Administration. Knowing the pollution was approaching Washington state, Price loaded sensing equipment aboard a rented Beechcraft on April 14 and flew to Neah Bay on the state's Northwest coast. Taking samples at various levels from 15,000 feet to 20,000 feet in altitude, she monitored 10 quantities of dust, ozone, carbon monoxide and hydrocarbons. "From my copilot's seat, the dust was thick enough to see with the naked eye," Price said. Now she 's trying to correlate her findings with those of the two research teams operating on the other side of the Pacific, where at one point the pollution plume was larger than Japan. The huge size of the cloud showed up clearly in satellite images that gave Price plenty of warning the haze was on its way. "You can see these two blobs coming out of the deserts of Mongolia and growing over Asia, then getting swept out over the ocean and finally setting over North America," she said. She intends to continue measuring air samples off the Washington coast and will be looking for air masses with evidence of pollution originating somewhere other than Asia. "We'd like to see if we can get a signature of pollution coming from Europe because computer models suggest that European sources also can be transported across the pacific," she Said. "However, we expect that sources in Europe will contribute less than Asian sources. /
