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'?

  A. Three.        B. Four       C. Five      D. Six

3.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.

4.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.

 

The worst danger is a house on fire when people are asleep. Always be ready to leave through a window into the garden by making sure you can open it if necessary. If you should be on holiday in a tall building or hotel, make sure you know where the fire escape（太平梯） is . When you can’t find any way out, try to find pieces of cloth and make a rope to get out of a window to safety. If you smell burning in your home, get out right away. If you can’t breathe properly because of smoke on your way out, crawl（爬行） on your hands and knees because smoke rises and the air will be cleaner near the floor. Smoke is a killer and more people have died from breathing it in than actually being burnt.
Fire in a cinema, hall or public place often means people pushing to reach a door. Keep your head up with arms up in front of your chest（胸）.This protects your chest and gives you the best chance to breathe. Above all, don’t get frightened!
