四、阅读理解。
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 (喷射) stream. The jet stream is a vey high altitude wind which always blows from the west to the east across the Atlantic. The planes moving at a constant air speed go faster in the west-east direction when they are moving with the wind than in the opposite (相反的) direction.
What would happen if the gravity (重力) on Earth was suddenly turned off?
Supposing we could magically turn off gravity. Would buildings float awa? What happened would depend on how strongly the things were attached to (附着) 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 (细绳), it goes around in a circle until you let go of the string. Then it flies off in a straight line. “Switching 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. Most things outside would fly off into space.
