Imagine the situation. You are driving a...

Imagine the situation. You are driving alone in a desert or on a mountain. You have no idea where you are. You passed the last house two hours ago. Then your car breaks down. It is night and it is cold. You have no mobile phone. What do you do? Well, next time take a GPS with you. This invention may be able to help you. It is a device(装置) which uses satellites to find the users’ position. It can find your position within 20 metres. A GPS cannot start your car, but at least you will know where you are.

The GPS, which means the Global Positioning System, is a small radio receiver. It looks like a mobile phone. You can hold it in your hand, or put it in your pocket. It is sometimes put into a watch or a telephone. We also find GPS devices in cars, planes, or boats. Some of these devices have electronic maps, so you know where you are. For example, in a city they can tell you the name of the street.

There are three parts to the Global Positioning System. The first part is the receiver. You can hold it in your hand, or have it fixed into your car, plane, etc. The second part is a group of satellites orbiting the Earth. The receiver contacts at least four of the satellites and calculates its position. The third part of the system is a network of ground stations. They are all over the world. They control the satellites and make sure they are working well.

Some people think that in the future the GPS will be as common as the mobile phone. They are becoming cheaper and more and more accurate. There are also new uses for the GPS. Perhaps they will become like watches. Everyone will have one and you will never be lost again.

1.According to the passage, with the help of the GPS, people ____________.

A. can’t be lost in a new city

B. can’t find their way in different countries

C. can learn about the culture of an unknown place

D. can spend the least time getting to another place

2.We can learn from the passage that __________.

A. a GPS can help you start your car

B. a GPS can’t be put into a watch

C. there are three parts to the GPS

D. the GPS are becoming more and more expensive

3.The underlined word “They” in paragraph 3 means ___________.

A. Receivers           B. GPS devices

C. Satellites          D. Ground stations

4.The passage is mainly about __________.

A. the history of the GPS        B. the introduction of the GPS

C. the shape of the GPS          D. the three parts of the GPS

5.What can we learn from the passage?

A. All GPS devices have electronic maps.

B. The GPS can not only start your car but also know where you are.

C. The receiver of the GPS contacts all the satellite to calculate its position.

D. The GPS will become more and more common in everyday life.

When thirty-two-year-old tennis player Andre Agassi made to the final of the U.S. Clay Court Championship in April 2003, he set a new world record: he became the oldest player ever to be number one in the world’s tennis rankings. It was one of the greatest achievements in Agassi’s long and successful career.

Andre Agassi turned professional in 1986 at the age of sixteen. His career soon took off, and in 1990, Agassi was famous around the world, though never having won an important tennis championship. Many people thought he was famous more for his long blond hair and colorful tennis shirts than for his tennis skills. They wondered if he could really win an important tournament.

In 1992, Agassi proved these people wrong by winning one of the greatest prizes in world tennis—the Wimbledon singles final. His first attempt to win this tournament had been in 1987, but he lost his opening game. He then refused to take part in Wimbledon for the next three years. He said his reason for not playing was that the officials refused to allow him to wear his colorful shirts, but some people said it was because he was afraid to lose.

After several more championship victories, Agassi’s luck began to run out. By 1997, the year of his marriage to a movie actress--- Brooke Shields, Agassi’s ranking had dropped to 141st in the world. Many people thought his career was over.

Agassi and Shields divorced two years later, and Agassi made a comeback with a new trainer, a new hairstyle, and new determination. In 1999, he won both the French Open and the U.S. Open and ended the year back as the world’s number one. By 2003, he had earned more than $27 million in prize money, making him one of the most successful tennis players of all times.
