What do you do if you're stranded（处于困境的）on a lonely island? Surely you need to find a way to get in touch with the outside world. Your best chance of doing this is to draw the attention of a passing plane.

　　Body signals（信号）

　　Pilots from different countries understand body signals if they have the correct training. When you wave your arms up and down in a straight line, it means "yes". When you point downwards and swing your arm from side to side, it means "no". If you want the pilot to know that it's safe to land, push your hands out in front of you and bend（弯曲）your knees. If you want to say that it's not safe to land, put your arms in the air and move them to one side.

　　Smoke signals

　　The smoke from a fire can be seen from far away, so it's a good way to draw attention. If the weather is dry, it isn't hard to start a fire. Remember, however, that fires can be very dangerous if they get out of control. Never light a fire unless you're sure that it can't spread. If the ground is dark, light smoke can be seen more easily. Green grass and leaves produce light smoke.

　　Ground-to-air signals

　　It's a good idea to build some signals, too. Use large pieces of wood to make the symbols(标记). If you can't find any wood, use earth. Some useful symbols are:

　　F "I need food and water."

　　II "I need medicine."

　　I "I am badly hurt."

　　X" I am unable to move from here."

　　Pilots' replies

　　If the pilot lowers the plane's wings from side to side, this means "message received and understood". (At night, the pilot flashes the plane's green lights.) If the pilots flies the plane in a clockwise circle, this means "message received but not understood".(At night, the pilot flashes the plane's red lights.)

However, there is no signal which means "message not received". Why not?

1. Which picture means "it's not safe land"?

2. What can we learn from the passage?

　　A. Swinging your arm from side to side means "yes".

　　B. If the ground is dark, light smoke can't be seen.

　　C. If you need some medicine, make a symbol "II".

　　D. The pilots make replies with a blue light at night.

　　3. What is the passage mainly about?

　　A. The explanation of building signals on an island.

　　B. The importance of making signals on an island.

　　C. Ways of sending out signals on a lonely island.

D. Ways of receiving signals from a lonely island

I want to tell you a story about myself at the airport. I wanted to fly to France with my family on vacation. Before we took the plane, we had to go through the metal detector (金属探测仪) at the airport. When I walked through it, the alarm rang.

“Come here, young man.” said the guard at the airport. “Take everything out of your pockets. ” So I took my wallet out and put it on the table. Then I walked through the metal detector again. This time, the alarm didn’t ring. My mother said that maybe there was something made of metal in my wallet, but I didn’t think so. Anyway, we got on the plane successfully and flew to France. The trip was great and I had a good time there.

When we went to the airport in France to fly home, I got into trouble again. When I went through the metal detector, the alarm rang again. I was surprised, so I asked the guard about it. “Let me see what’s in your wallet,” said the guard. So I took out everything out of my wallet. “This one is made of metal,” said the guard, pointing at the pen I bought last week.

1.Did the writer go through the metal detector successfully for the first time?

Many people like to travel by plane, but l don’ like it because an airport is usually far from the city. You have to get there early and wait for hours for the plane to take off (起飞) and it is often late. You can’t open the windows. You can’t choose the food. Planes are fast but they still take much time to go out of the airport and into the city.
I like traveling by train .I think trains are safe. Railway stations are usually in cities. When you are late for a train, you can catch another one. You can walk around in the train and open the windows .You can see many interesting things on your way. I know it takes a little more time.
I also like cars. You can start your journey whenever you want to, and you don’t need to get to a railway station or a bus stop. Also you can carry many things with you in a car. But sometimes there are too many cars on the road.
