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
Dereck Joubert and his wife, Beverly, have made many films about wild animals in Africa. Their films and photographs are very popular and one of the photographs has been on the front cover of a National Geographic magazine.
A working day foe Dereck and Beverly starts very early-at 4:30 in the morning! That's when they get up and start filming. And it's a long day-they often work until 8:30 in the evening. In the winter it's very cold and in the summer it can be 40℃. Dereck always does the filming-Beverly never does that, and she doesn't write. But Dereck never takes photographs or records the sound. They work very well as a team, and they both believe we should shoot animals with cameras-not with guns!
When they have finished filming and taking photographs for the day, they have dinner and Dereck usually writes while Beverly looks at her photographs. At night, they usually sleep in a small tent, but they sometimes sleep in the Land Cruiser-when you're very close to wild animals, it's sometimes safer to sleep in the car.
Dereck and Beverly have also traveled around the world and given talks about their work. Dereck says that animals are not just something to look at-they play an important role. Beverly thinks the wild animals can teach us a lot about ourselves.
