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?
【小题1】 Which picture means "it's not safe land"?
【小题2】 What can we learn from the passage?
【小题3】 What is the passage mainly about?

shopping and want to buy some clothes，you should
think about which kind of clothes you really need and decide how much money you
can spend on them．Then look at the labels that are
inside the new clothes. They tell you how to take care of the clothes．The label for a shirt may tell you to wash it in warm
water. A sweater label may tell you to wash it in cold water. The label on a
coat may say “dry clean only” and cleaning in water may ruin this coat. If you
do as the directions say on the label, you can keep your clothes looking their
best．
