[EX Q]: Article: For children with cancer ,the facts of life include the facts of death. There is always the fear that they might not live to grow up.Yet they realize that fighting cancer is the only way of beating it. So they fight.And sometimes, they win.It may take years.It certainly takes support from parents and doctors. Unfortunately, many parents can't deal with their child's illness.And doctors, no matter how caring, have other patients to care for. At times like these, the Children's Cancer Foundation can help. We are a group of Hong Kong doctors, nurses, psychologists, parents of children with cancer and concerned persons .All of us are volunteers (offer one's help without payment).We're with the children every day, listening to, and encouraging them. We also advise parents, educate the public and send doctors overseas to study new cancer treatments. Our funding (providing money) has brought better equipment to the wards (large rooms of a hospital), and paid for special flats where the children can recover. We want to do even more.But to do it, we need your help. It will be money well spent.One who looks at our past achievements should prove that. To the children, your contribution will also be a show of support.A sign that you're behind them is just the sort of news that a six-year-old chlid with cancer needs to hear.

[EX Q]: Article: It seems like every day there's some new research about whether our favorite drinks are good for us. One day, science says a glass of red wine a day will help us live longer. The next day, maybe not. It seems journalists are pretty interested in wine research and the same might be said for coffee. Now there's been a lot of research into whether coffee's good for our health "the results have really been mixed",admits Neal Freedman who led the coffee study and published his findings in a medical journal recently. "There's been some evidence that coffee might increase the risk of certain diseases and there's also been maybe more recent evidence that coffee may protect against other diseases as well". Freedman and his colleagues undertook the biggest study yet to look at the relationship between coffee and health. They analyzed data collected from more than 400,000 Americans ages 50 to 70 participating in the study. "We found that the coffee drinkers had a modestly lower risk of death than the non-drinkers, he said. Here's what he means by "modestly": those who drank at least two or three cups a day were about 10 percent or 15 percent less likely to die for any reason during the 13 years of the study when the researchers looked at specific causes of death, coffee drinking appeared to cut the risk of dying from heart disease, lung disease injuries, accidents and infections. Now, Freedman stressed that the study doesn't prove coffee can make people live longer .A study like this can never prove a cause-and-effect relationship. All it can really do is to point researchers in the right direction for further investigation. And even if it turns out that coffee is really good for you, scientists have no idea why.

[EX Q]: Article: Throughout history there have always been people who can make other people laugh. Early clowns often both annoyed and delighted listeners with their comments and songs. They were not the silent performers seen in today's circus rings. Clowns _ when the big three-ring circuses made it impossible for the audience to hear them. Circus clowns give performances in various ways. Walk-around clowns use an animal or something, like a huge rubber hammer, as part of their performance. A carpet clown moves around, talking with the audience and performing while the acts change in the rings. Then there are acrobatic clowns, riding clowns, juggling clowns and others. Everything a clown does looks easy, but it is not. Making people laugh can be hard work. Clowns must be in good physical condition to prevent injuries. Each funny move is carefully timed and well-rehearsed . Most clowns have also been trained as acrobats, jugglers or aerial artists, and many include such skills into their acts. Generally, there are three types of circus clowns--whiteface, auguste and character. Each has a special makeup and clothes. Each has a typical act as well. The neat whiteface is usually a strict, in-charge character who sets up the punch line (the point of a joke) with a partner who is typically an auguste. His facial makeup is neatly detailed in red or black, and his clothes look so loose with a ruffle around the neck. Old circus stories have it that the auguste clown got his name from a German nickname for someone who is clumsy, acting in a careless and stupid way. The auguste wears light-coloured makeup, but white is used around the mouth and eyes, and there's a big red nose. This clown performs a great deal of humour. An oversized suit or baggy trousers allow freedom of movement for all the clumsy acts. He also wears big shoes. Character clowns perform as different characters--cowboys, grandmothers or concert conductors. The most famous character clown, however, is the tramp . Tramps wear different styles of makeup and torn clothes. Some tramp clowns are happy-go-lucky. Others are extremely sad. Still others act like gentlemen who just happen to be out of money.
