听力题 Smoking is even more dangerous than previously believed, according to a major review of medical data by the World Health Organization''s cancer agency. The International Agency for Research on Cancer (IARC) also published the first evidence to link second hand smoke with increased risk of cancer. The agency convened 29 scientists from 12 countries to review all significant published research on both active and passive smoking. They state explicitly that even an average degree of passive exposure to tobacco products can cause lung cancer in people who have never smoked. "It''s been suspected for a long time," said Professor Richard Doll, one of the report''s authors, "but this is the first time we''ve had a clear scientific consensus saying it''s definitely a cause." Fifty years ago, Professor Doll was a joint author of the first published paper to suggest a link between tobacco and lung cancer. The agency''s report also implicates tobacco in five cancer sites not previously shown to be associated with smoking—the stomach, liver, uterine cervix, kidney (renal cell carcinoma), and myeloid leukaemia. "The additional risk to these sites from smoking varies from about 30% to double," said Professor Doll. " Some were previously suspected, but this is the first time there is solid evidence." Cancers normally linked to hormonal causes seem to be unaffected by smoking. In particular, the agency''s working group rejected suggestions that passive smoking can cause breast cancer. The agency was unable to provide a definitive answer, however, to the question of whether passive smoke by children in the home is linked to childhood cancers.

听力题 In Britain there are 11 national daily newspapers and most people read one of them every day. There are two kinds of newspaper. One is large in size and has many detailed articles about national and international events. These newspapers are called the serious papers or the quality papers. The other kind, called the tabloids, are smaller in size, have more pictures, often in color, and short articles, often about less important events or about the private lives of well-known people. Although some people disapprove of tabloids, knore people buy them than buy the serious newspapers. The Sun, for example, which is a tabloid, is the biggest-selling newspaper in Britain. The tabloids are sometimes called the gutter press. And in 1997, some photograph reporters of the tabloids were said to be involved in the tragic death of Princess Diana in France and they were criticized as Paparazzi by the public. Most national newspapers in Britain express a political opinion and people choose the newspaper that they read according to their own political beliefs. Most of the newspapers are right-wing which means they support the Conservative Party. These are the Daily Telegraph, which is the serious newspaper, the Daily Express, Daily Mail, Daily Star, the Sun and Today, which are all tabloids. Of the other serious newspapers, The Times, the oldest newspaper in Britain, did not formerly have one strong political view but it is now more right-wing. The Independent does not support any political party, and neither does the Financial Times, which concentrates on business and financial news. The Daily Mirror is the voice of the Labor Party.

听力题 A team of scientists recently began a project to measure the effects of loud noises on sea animals. If the sounds don''t harm the animals, then the researchers can go ahead with a plan to transmit sound waves through the Pacific Ocean to take the earth''s temperature. Sound travels faster through warm water than cold water. By analyzing the speed of sound through the ocean over a time, the scientists will be able to determine if our planet is warming up. The experiment was nearly cancelled more than a year ago because environmental groups feared that the sound would confuse or harm the sea animals. So, scientists are conducting tests on the animals first. The researchers lowered a loud speaker that emits low frequency sound about 1000 meters beneath the ocean. Scientists at the site transmit sound waves into the ocean. Radio transmitters attached to some of the sea animals help the researches keep track of the animals'' movements. If sea-animals are distressed by the sounds, they would swim away from the speakers. So far, there aren''t any signs that the animals are being harmed. Researchers at the site noticed that large numbers of sea animals swim near the speaker whether it was turned on or off, but it is still too soon to know for sure, the scientists admit. The test will continue through September. "If all goes well," they say, "we can begin measuring temperature changes on our planet."

听力题 The term "balanced diet" is constantly heard but rarely explained. What it means is a diet that includes a combination of several different food types, including grains, fresh fruit and vegetables, meat, dairy products, fats and oils. Crucial to the idea of a balanced diet is including foods in the right proportions; the aim is to get all the nutrients your body needs while maintaining a healthy weight. The US government provides a basic idea of what nutrients we need on their website. It isn''t a case of having roughly equal measures of everything. There should be a lot of some kinds and just a little of others. Some fats and oils, for example, are important in the diet for various reasons. But you only need a small amount compared with foods such as vegetables. In the UK, the Food Standards Agency has developed a programme called The Balance of Good Health to show people what proportions and types of foods make up a healthy balanced diet. This divides foods into five different groups. The largest groups are bread and vegetables, followed by milk and meat. The smallest by far is the salt and sugar group. Fresh fruit and vegetables are low in fat, calories and salt, and an excellent source of vitamins, minerals and fibre. Most of us don''t eat enough to meet the current recommendation of three to five servings of vegetables and two to four servings of fruit a day. Protein-rich foods and dairy foods are needed in more moderate amounts. Your diet should include two to three servings of milk or dairy products a day, for example.

听力题 A lot of people in the United States are coffee drinkers. Over the last few years, a trend has been developing to introduce premium, specially blended coffees—known as "gourmet coffees" —into the American market. Boston seems to have been the birthplace of this trend. In fact, major gourmet coffee merchants from other cities like Seattle and San Francisco came to Boston, where today they''re engaged in a kind of "coffee war" with Boston''s merchants. They are all competing for a significant share of the gourmet coffee market. Surprisingly, the competition among these leading gourmet coffee businesses will not hurt any of them. Experts predict that the gourmet coffee market in the United States is growing and will continue to grow, to the point that gourmet coffee will soon capture half of what is now a 1.5-million-dollar market and will be an 8-million-dollar market. Studies have shown that coffee drinkers who convert to gourmet coffee seldom go back to the regular brands found in supermarkets. As a result, these brands will be the real losers in the gourmet coffee competition. A lot of people in the United States are coffee drinkers.

听力题Questions 1 to 4 are based on the conversation you have just heard

听力题 Most people have had a dog or wanted one as their companion at some time in their lives. If you are thinking of buying a dog, however, you should first decide what sort of companion you need and whether the dog is likely to be happy in the surroundings you can provide. Specialist advice is available to help you choose the most suitable breed of dog. But in part, the decision depends on common sense. Most breeds were originally developed to perform specific tasks. So, if you want a dog to protect you or your house, for example, you should choose a breed that has the right size and characteristics. You must also be ready to devote a good deal of time to train the dog when it is young and give it the exercise it need to throughout its life, or to let it live in the country and can let it run freely. Dogs are demanding pets, whereas cats identify with the house, and so are content if their place is secure. A dog identifies with its master and consequently wants him to show proof of his affection. The best time to buy a baby-dog is when it is between 6 and 8 weeks old so that it can transfer its affection from its mother to its master. If baby dogs have not established a relationship with the human being until they are over three months old, their strong relationship will always be with dogs. They are likely to be too shy when they are brought out into the world to become good pets. Most people have had a dog or wanted one as their companion at some time in their lives.
