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

Hu Yaohui, a schoolgirl in Zhejiang province, didn’t want to speak or eat for a week. She kept worrying about her scores on the exam. “I can’t stop thinking about my place in the class,” she said. “I feel stressed out.”

Hu is not the only one who faces stress. According to a recent survey conducted by Wuhan University of Hubei province, 70 percent of the 2,000 students who are going to take the college and high school entrance exams feel under pressure (压力).

Stress is a normal physical response (反应) to things that make people feel worried or break their balance of life in some way.

Stress isn’t always bad. Sometimes, people’s stress is important during emergency situations, such as when a driver has to stop his car to avoid an accident. Sometimes, stress can help people do their best — like while getting ready before a big competition or exam.

However, too much or long-term stress gives people a stress overload (负荷过多). People with stress overloads may have problems remembering or concentrating on things. They are quick to get angry or lose patience. They may even have other problems, such as sleeping problems, headaches and often getting colds.

The most helpful way to deal with stress overloads is to learn how to manage the stress. For example, you might manage it by getting a good night’s sleep, or by exercising every day.

Another good way to deal with stress is to ask parents or friends for help. Everyone has stress. For many people, stress is so common that it has become a way of life. Don’t be too shy to tell others that you are having a hard time. They may comfort you or give you some useful advice. Sometimes just sharing your problems with someone else can make you feel better.
