求专业人士翻译2010安徽高考题B
Have you ever wondered?
1. 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 known as the jet(喷射)stream. The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic. The planes moving at a constant air speed thus go faster in the west-east direction when they are moving with the wind than in the opposite direction.

2. What would happen if the gravity on Earth was suddenly turned off?
Supposing we could magically turn off gravity. Would buildings and other structures(建筑物)float away? What happened would depend on how strongly the things were attached 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(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.

你有没有想过?
1。为什么飞机需要更长的时间比东飞西?
自西向东从纽约需要五个小时(纽约)去伦敦,但七小时的旅行从伦敦飞往纽约的东西。这种差异的原因是一种大气现象称为射流(喷射)流。喷射流是一个很高的高度风总是自西向东横跨大西洋。飞机在一个不断移动的空气速度从而走在东西方向的速度时,他们的风比在相反的方向移动。
2。如果地球引力突然关闭,会发生什么?
假如我们能用魔法把重力。将建筑物和其他结构(建筑物)飘走的?会发生什么取决于强烈的东西都连接到地球。地球是相当的速度移动,移动的速度达到每小时一千英里。如果你把你的头部周围的东西在一个字符串(细绳),它绕一圈直到你放开绳子。然后它会直线飞行。“关闭”的重力会放手的字符串。没有连接到地球的东西就会飞在一条直线上。建筑物里的人们会突然飙升在高速前进直到他们撞到天花板。最外面的东西都将飞向太空。
