Many teenagers feel that the most important people in their lives are their friends. They believe that their families don't know them as well as their friends do. In large families, it is quite often for brothers and sisters to fight each other and then they can only go to their friends for some ideas. It is very important and necessary for teenagers to have one good friend or a group of friends.

Even when they are not with their friends, they usually spend a lot of time talking among themselves on the phone. This communication with friends is very important in children's growing up, because friends can discuss something difficult to say to their family members.

Have you ever wondered?

Why do airplanes take longer to fly west than east?

It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon (大气现象) known as the jet stream (气流). The jet stream is a very high altitude (= above sea level) wind which always blows from the west to the east across the Atlantic. So the planes moving at a constant air speed go faster from the west to the east when they are moving with the wind than in the opposite.

What would happen if the gravity on Earth was suddenly turned off?

Supposing we could magically turn off gravity. Would buildings and other buildings float away? What happened would depend on (依靠) how strongly the things were attached (吸附) to the earth. The earth is moving at quite a speed, moving at over a thousand miles per hour. If you turn something around your head on a string, it goes around in a circle until you let go of the string. Then it flies off in a straight line. Turning off gravity would be like letting go of the string. Things not attached to the earth would fly off in a straight line. People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling (= top surface of a room). Most things outside would fly off into space.
