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?

如果你被困在孤岛上该怎么办?当然,你需要找到一种与外界联系的方式.你最大的胜算就是吸引经过的飞机的注意力.
肢体求救信号
如果各国飞行员经历过正确的训练的话,他们通常懂得肢体信号的.当你上下摇动你的手臂,表明你说：是.如果你把胳膊朝向下并且左右晃动表示你说：不是.（类似于点头摇头）.如果你要告诉飞行员这里迫降很安全,半蹲并把你的手向前推（作出飞机迫降的样子）.如果你想说这里迫降不安全,将你的胳膊从一边滑向另一边（表示飞机继续飞行）.
烟雾求救信号
火的熏烟在很远的地方就能被看到,因此它是绝佳的好方法.如果天干燥的话,点火就容易了.切记!一旦火势失控,那将非常危险.绝对不要点火除非你确信它不会蔓延.如果地面是黑色的那么,很容易看到地面上的烟雾.树叶和草用来制造烟雾.
地对空信号（顾名思义）
如果你能造一些求救信号那就再好不过了,用大木头来做标记,如果你找不到木头用土.一些有用的标记如下：
：我需要食物和水
我需要药物
我受重伤
我动不了了
飞行员的回复
一旦飞行员将飞机的两翼不断放低,这表明它收到消息并理解.（夜晚,飞行员常常是飞机放绿光) 如果飞行员开飞机在天空上以顺时针盘旋,则表明他收到信号但是没有理解你的意思.（夜晚常常放红灯）
但是,没有一种信号表明"没有收到讯号".为什么没有呢?
