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.

[EX Q]: Article: The most famous statue-the Sphinx in Egypt has been damaged. The experts are trying to find out the cause to protect it. As we all know, the Sphinx has the body of a lion and the face of a man. It was cut from limestone near Egypt's pyramids about 4, 500 years ago. Not long ago a large piece of stone fell from the Sphinx's right shoulder. In order to protect the statue from more harm, a computer was placed on it to measure rainfall, wind speed and air temperature. The computer also measured the amount of water and air pollution, the direction of wind and the temperature of the statue itself. The effects of age, wind, water and pollution have greatly weakened the Sphinx. Sunlight, wind, water and pollution have been eroding the outside of the statue for centuries. The experts hope that the information from the computer will help protect it from more damage. They say the more they know about what is destroying the Sphinx, the more they can do to protect it.
