1 . Modern life is impossible without traveling. The fastest way of traveling is by plane. With a modern airliner(客机), you can travel in one day to places which needed a month or more to get to hundreds of years ago.
Traveling by train is slower than by plane, but you can see the places you are traveling through. Modern trains have comfortable seats and dining-cars. They even make the longest journey enjoyable(令人愉快的).
Some people prefer to travel by sea. You can visit many other countries or different parts of your country. Ships are not so fast as trains or planes, but traveling by sea is a very pleasant way to spend a holiday.
Many people like to travel by car. You can make your own timetable. You can travel three or four hundred miles or only fifty or one hundred miles a day, just as you like. You can stop if there is something interesting, for example, at a good restaurant where you can enjoy a good meal, or at a hotel to spend the night. That’s why traveling by car is popular for pleasure trips, while people usually take a train or a plane when they travel on business.

2 . 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?
