　　As you grow rapidly through your teenage years, you will experience a lot of changes. The changes may seem difficult. 　1　 　Don’t panic! You will deal successfully with them! You are a young adult now!
　　With more responsibility, you will find more freedom to make your own choices. This is a time to be well informed about making choices. In this way you can make healthy balanced decisions. 　2　 　You may already know your career path or you may have no idea at all what you want to do. Both situations are fine! Work hard and the right opportunity will present itself to you.
　　Young adulthood means greater freedom and more choices. 　3　 　But try not to shut your family out of your life. You should learn to think of others even though you are old enough to look after yourself.
　　It is also perfectly natural at this time for you to spend more time with your friends than your family. Choose your friends wisely. A true friend will stand by you no matter what happens.
　　This period is a part of the life cycle. There are some people who will be with you throughout life’s journey. There will be some people with whom you part and go separate ways. Leaving school can be hard. The reality is that you may not even see all of your classmates again.
　　You are a young adult. It is your life. No one can live it for you. 　4　 　So making the right choices will be important to you. Life is for living. Enjoy your life wisely.

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
