Q: Article: Signs in Chinese will be set up in public areas such as airports, to benefit Chinese travelers, the Italian Government announced in late February. _ . Despite the different languages, travel across Europe has never been so simple. Just five years ago, if you wanted to visit Germany in the north and Spain in the south in one trip, you had to wait for weeks to apply for different visas from the two countries. You also needed a calculator because both countries had different money. Today, with a Schengen Visa issued by any member country, you can travel across 15 European countries without stopping. Since 2002, within most of the EU, there is now just one type of money called the Euro. The Euro was designed to be the only money in the EU, and already makes it easier to shop around. If you drive, your driving license and car insurance policy are valid in the other European countries. And you can use your mobile phone everywhere. All the countries in the continent are melting into a united Europe under the EU. For Europeans and visitors, the result is that it is more convenient to travel back and forth between the different countries.

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.

Q: Article: As we all know, millions of people worldwide cook their food over smoky fire every day. It is often difficult to find wood for the fire. People who do not have wood must spend large amounts of money on cooking fuel. However, there is a much easier way to cook food using energy from the sun. Solar cooker, or ovens, have been used for centuries. A Swiss scientist made the first solar oven in seventeen sixty-seven. Today, people are using solar cookers in many countries around the world. People use solar ovens to cook food and to heat drinking water to kill bacteria and other harmful organisms. There are three kinds of solar ovens. The first is a box cooker, It is designed with a special wall that shines or reflects sunlight into the box .Heat gets trapped under a piece of glass or plastic covering the top of the cooker. A box oven is effective for slow cooking of large amounts of food. The second kind of solar oven is a panel cooker. It includes several flat walls or panels that directly reflect the sun's light onto the food. The food is inside a separate container of plastic or glass that traps heat energy. People can build panel cookers quickly and with very few supplies. They do not cost much. In Kenya ,for example ,panel cookers are being manufactured for just two dollars. The third kind of solar oven is a parabolic cooker. It has rounded walls that aim sunlight directly into the bottom of the oven .Food cooks quickly in parabolic ovens .However, these cookers are hard to make. They must be re-aimed often to follow the sun .Parabolic cookers can also cause burns and eye injuries if they are not used correctly. You can make solar ovens from boxes or heavy paper. They will not catch fire. Paper burns at two hundred thirty-two degrees Celsius. A solar cooker never gets that hot. Solar ovens cook food at low temperatures over long periods of time. This permits people to leave food to cook while they do other things.
