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 phones. What do you do? Well, next time take a GPS with you. This invention may be able to help you. It is a device which uses satellites (卫星) to find the user’s position(位置). It can find your position to within 20 meters. 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 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 satellites and make sure they are working well.
Some people think that in the future the GPS will be as common as the mobile phones. They are becoming cheaper and more and more accurate. There are also new uses for the GPS. Perhaps they will be like watches. Everyone will have one and you will never get lost again.. According to the passage, with the help of the GPS, people __________.
A.can’t find their directions in different countries |
B.can always find where they are |
C.can learn about the culture of an unknown place |
D.can spend the least time getting to another place |
. The underlined word “They” in paragraph 3 means ____________.
A.Receivers | B.GPS devices |
C.Satellites | D.Ground stations |
We can learn from the passage that ____________.
A.GPS can’t be put into a watch |
B.GPS are becoming dearer and dearer |
C.People can start their cars with a GPS |
D.People can’t lose their way with a GPS when driving |

A lift is wonderful. It is really only a small room. Rooms usually stay in one place. Lifts travel up and down all day long.
Sometimes a worker stands in the lift. He or she operates it up and down. In modern lifts there is no worker. The people walk in. They know what floor they want. They push a button and the lift goes to that floor. It is all very fast and easy.
Lifts are very important to us. Why? Think about a tall building. Maybe it has twenty floors. Maybe it has fifty or more. Who can walk up all the stairs? Maybe people can climb them one time. Can someone climb thirty floors to an office every day? Can small children walk up to their room on the twenty-fourth floor? Can their mother and father carry food up all those stairs? Of course not.

Whether summer or winter, holiday time can mean travel. A few years ago, some people moved from California to Maryland with their birds. Traveling with birds is a very unusual experience. But everything can go well with a little planning. There are some good tips for you.
★ The first thing you have to decide is what cage your birds will use. You should make sure that the cage is neither too small nor too big, and can be put into the car easily. If you find that you need a travel cage, get it a few weeks before the trip, so you can give your birds time to get used to it.
★ If your car has the airbag, do not put the cage in the front seat. The force of the airbag even in a little accident could easily damage any cage and even injure or kill the bird inside. The cage should be held in the car with seatbelts.
★ If your trip takes several days, you need to make some stops at pet-friendly hotels. When you stop at hotels during the trip, you must put lots of newspapers under the cage to help control the rubbish.
★ If your travel or moving plans bring you to areas with hot weather, remember that the car will become very hot in a short time in the sun. Never leave your birds in the car alone.
Traveling with birds can be stress-free, and a little planning can make it a pleasant experience.What is the first thing you have to decide?
