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

Like many people ,I have no clear idea about heroes . A t some point , we all wonder if we need a hero and what a hero really is.

Although there are a lot of differences in cultures, heroes around the world generally share a number of characteristics (特点) which give us courage  and make us want to learn from them.

A hero does something worth (值) talking about, A hero has a special story to tell and people think highly of it. But a hero is not just person with great fame (声誉).

A hero has power(力量) larger than himself . Some people want to live like a hero. And they have to experience life with new and further meaning .A sure test for would- be heroes is what or whom they serve. What do they want to live and die for? If their answer suggests they serve only own fames, they may be famous persons but not heroes.

A hero has a vision from the mountain top .He has the power to move people . He creates new possibility. Without Gandhi, India might still be part of Britain, Without Martin Luther King .Jr, Americans might take different parks , and shop in different stores of the different colors of their skins.

There might be changes in society without a hero, but the speed of the change would be rather slow . Thanks to heroes in history ,they make the society develop so rapidly.
