If a snake bites you, take a photo with your mobile phone! It may save your life. This is the surprising of a British cook.

One day Henry Jackson was working in a restaurant kitchen. He picked up a dish from the table, and a snake appeared...and bit him on the hand.

A few days earlier, the snake came to the from Asia in a box of bananas. It climbed out of the box and under the dish.

“I went to try to pick it up and it bit me again. I threw it 25 the kitchen, and it landed in the fridge. So I closed the door,” Mr Jackson said.

Anyway, Mr Jackson stayed and he took a photo of the snake with his mobile phone. Soon his began to ache and he went to hospital. Then his chest began to hurt. Doctors couldn’t say what was wrong w what kind of snake it was.

Ⅳ.阅读理解（每小题2分，共28分）

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 (卫星) to find the user’s 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. 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.

A. can’t be lost in a new city

B. can’t find their way in different countries

A. there are three parts to the GPS

B. a GPS can’t be put into a watch

C. a GPS can help you start your car

D. the GPS are becoming more and more expensive

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

C. Satellites D. Ground stations

34. The passage is mainly about ______________.

A. the history of the GPS

B. the introduction of the GPS
