Imagine the situation. You are driving ...

 

 

Imagine the situation. You are driving along 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 (卫星) to find the users position(位置). It can find your position to within 20 metres. A GPS cannot start your car, but at least you will know where you are.

GPS, which means Global Positioning System, is a small radio receiver. It looks like a mobile phone. You can hold it in your hand, or put 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(计算) 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. They are becoming cheaper and more and more accurate(精确的). 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.cant 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.there are three parts to the GPS

B.a GPS cant be put into a watch

C.a GPS can help you start your car

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 infer(推断) from the passage?

A.All GPS devices have electronic maps.

B.People in many countries will use the GPS for free.

C.The receiver of the GPS contacts at least five of the satellites.

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

On a rainy day, about 150 volunteers worked for eight hours to clean up Carson Creek that is near a river. About nine tons of trash was taken out from there. 

“We did a good job,” said Alan Specter, the organizer of the event. “We’re planning to come back here one more time, three years from now. Of course, we hope that there won’t be so much trash next time.”

The trash came in all shapes, sizes, and colors: cans, bottles, bicycles, batteries, furniture, clothing, plastic bags, dolls, and even a golf bag with a full set of golf clubs (球棒). 

The dirty and tiring work was done by two volunteering groups — Save the Bay and Watch the Whales. Most of the volunteers came from a local police station and a fire station. And some of them were old people who had already retired (退休). 

That day, it rained a little. All of them wore boots, gloves and raincoats. They did the work along a two-mile river with over 500 big yellow trash bags everywhere. 

No one found anything that cost much. A five-year-old boy found an earring which he thought might be worth a million dollars. He said he’d sell it. Then he’d donate half of the money to Watch the Whales, and use the other half to buy his favorite ice cream every day. 

Many people laughed at the boy’s story. However, it was easily found that the environment there did become better.

2.What do you know about the volunteers?

A. They were old and poor.    B. They liked collecting old things.

C. They hated to live near the river.    D. They were interested in volunteering.

3.What does the underlined word “donate” mean in Chinese?

A. 寻找    B. 遗留    C. 偿还    D. 捐赠

4.Which of the following is NOT true according to the passage?

A. There was more trash when the volunteers left that day.

B. The volunteers planned to come back again after three years.

C. In fact, the earring which the small boy found cost little.

D. A lot of trash was thrown around along the two-mile river.

5.Which may be the BEST title for the passage?

A. Rainy days    B. A boy’s dream
