Our risk of cancer rises dramatically as we age. So it makes sense that the elderly should be routinely screened for new tumors -- or doesn't it? While such vigilant tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly. With the percentage of people over age 65 expected to nearly double by 2050, it's important to weigh the health benefits of screening against the risks and costs of routine testing. In many cases, screening can lead to additional biopsies and surgeries to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not pose serious health problems in patients' remaining years. But the message that everyone must screen for cancer has become so ingrained that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a riotous reaction among doctors, patients and advocacy groups. It's hard to uproot deeply held beliefs about cancer screening with scientific data. Certainly, there are people over age 75 who have had cancers detected by routine screening, and gained several extra years of life because of treatment. And clearly, people over age 75 who have other risk factors for cancer, such as a family history or prior personal experience with the disease, should continue to get screened regularly. But for the remainder, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy . A recent study suggests that doctors start to make more objective decisions about who will truly benefit from screening- especially considering the explosion of the elderly that will soon swell our population. It's not an easy calculation to make, but one that make sense for the whole patient. Dr. Otis Brawley said, "Many doctors are ordering these tests purely to cover themselves. We need to think about the rational use of health care and stop talking about the rationing of... Why do many doctors prescribe routine screening for cancer? A) They want to protect themselves against medical disputes. B) They want to take advantage of the medical care system. C) They want data for medical research. D) They want their patients to suffer less.

The Crowne Plaza Hotel in Copenhagen is offering a free meal to any guest who is able to produce electricity for the hotel on an exercise bike linked to a generator ,The idea is to get people fit and reduce their carbon footprint. Guests will have to produce at least 10 watt hours of electricity -- roughly 15 minutes of cycling for someone of average fitness. Guests staying at Plaza Hotel will be given meat tickets worth $36 once they have produced 10 watt hours of electricity. The bicycles will have smart phones attached to the handlebars measuring how much power is being generated for the hotel. The plan, a world-first, will start on 19 April and run for a year. Only guests staying at the hotel will be able to take part. Frederikke Toemmergaard, hotel spokeswoman, said, "Many of our visitors are business people who enjoy going to the gym. There might be people who will cycle just to get a free meal, but generally I don't think people will take advantage of our programme," Copenhagen has a long-standing cycling tradition and 36% of locals cycle to work each day, one of the highest percentages in the world, according to the website visitcopenhagen.dk. US environmental website treehugger.com recently voted Copenhagen the world's best city for cyclists. "Because Copenhagen is strongly connected with cycling, we felt the bicycle would work well as a symbol of the hotel's green profile ." If successful, the electric bicycle meal programme will be spread to all Crowne Plaza hotels in the UK, the hotel said in a statement. Who are most likely to enter for the programme? A) The poor local people. B) The environment activists. C) Health-conscious hotel guests. D) Visitors fond of Copenhagen food.

Q: He was the baby with no name. Found and taken from the north Atlantic 6 days after the sinking of the Titanic in 1912, his tiny body so moved the salvage workers that they called him "Our baby". In their home port of Halifax, Nova Scotia, people collected money for a headstone in front of the baby's grave, carved with the words: "To the memory of an unknown child." He has rested there ever since. But history has a way of uncovering its secrets. On November 5 , this year, three members of a family from Finland arrived at Halifax and laid fresh flowers at the grave. "This is our baby," says Magda Schleifer,68,a banker. She grew up hearing stories about a great-aunt named Maria Panula, 42, who had sailed on the Titanic for America to be reunited with her husband. According to the information Mrs Schleifer had gathered, Panula gave up her seat on a lifeboat to search for her five children----including a 13-month-old boy named Eino--from whom she had become separated during the final minutes of the crossing. "We thought they were all lost in the sea." says Schleifer. Now, using teeth and bone pieces taken from the baby's grave, scientists have compared the DNA from the Unknown Child with those collected from members of five families who lost relatives on the Titanic and never recovered the bodies. The result of the test points only to one possible person: young Eino. Now the family see no need for a new grave. "he belongs to the people of Halifax," says Schleifer. " They've taken care of him for 90 years." Adapted from ,November 25 ,2002 What is probably the boy's last name? A) Schleifer B) Eino C) Magad D) Panula

In Vietnam, Tet-Trung-Thu, or the Mid-Autumn Festival, is one of the most popular family holidays. It is held on the 15th day of the 8th lunar month. Vietnamese families plan their activities around their children on this special day. In a Vietnamese folk story, parents were working so hard to prepare for the harvest that they left the children playing by themselves. To make up for that time, the parents would use the Mid-Autumn Festival as a chance to show their love and thanks for their children. As a result, the Mid-Autumn Festival is also called the Children's Festival. In the United States, this tradition continues in many Vietnamese-American families. Activities are often centered on children and education. Parents buy lanterns for their children so that they can take part in a candle and lantern parade at dawn. Lanterns mean brightness, while the parade means success in school. Vietnamese markets sell a variety of lanterns, but the most popular children's lantern is the star lantern. Other children's activities include arts and crafts in which children make face masks and lanterns. Children also perform traditional Vietnamese dances for adults and take part in contests for prizes. Unicorn dancers are also very popular. Like Chinese people, Vietnamese parents tell their children folk stories and serve moon cakes and other special treats under the bright moon. A favorite folk story is about a carp that wanted to become a dragon. The carp worked and worked and finally changed itself into a dragon. Parents use this story to encourage their children to work hard so that they can become whatever they want to be. In both Vietnam and China, during the Mid-Autumn Festival, people would _ . A) eat moon cakes B) buy lanterns for children C) take part in contests D) buy a carp
