Everyone dreams of changing the world．But can teenagers really make a difference? And how can they go about it?

Michael Norton’s book 365 Ways to Change the World is a good starting point．The book gives an idea or a task for every single day of the year．The tasks include volunteering at a local homeless shelter（避难所）and hugging（拥抱）a tree．

    The book says that one simple act, no matter how small，call help someone in need．It may even influence other teens to do something.

    Nathan Anthony, a junior student at Enoch’s High School in Modesto，California, US agrees．”It is impossible to get anything in life without giving something to someone or making an effort at school or work, ”Anthony said．

    Another Enoch’s junior, Arianne Mote，has the same opinion．”Giving is our way of repaying those who help us，”she said。”Whether it is a helping hand or a donation（捐赠）：we should help others to improve their lives．”

But how often do teens see peers helping a stranger or doing something？ According to Anthony, not a lot. Mote and he both believe this needs lo change.

"Humor is also a great tool," Anthony' said. "It can help us a lot when we face some  embarrassment （尴尬） and it is a good way to solve some problems."

So whether you're helping to find a cure for cancer or simply smiling at a stranger, do something every day to help change the world for the better.

What do you do if you're in trouble 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 tire 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 lo 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 lo 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 pilot flies the plane in a clockwise circle, this means "message received hut not understood" (At night, the: pilot flashes the plants red lights.)

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