the sun rises in the east and sets in the west, which is caused by the rotation of the earth as you all know. but have you ever thought of the effect of the earths rotation on man and can you imagine what would happen if the earth stopped rotating?
the radius of the earth is about 6,370 kilometres. it takes the earth 24 hours to rotate once. objects on the earths equator move with the earth at a speed of 460 metres per second, and the air close to the earths surface turns at the same speed. if the earth stopped rotating suddenly, the air would keep flowing eastward at a speed of 460 metres per second. the wind would be fourteen times as powerful as a hurricane. at the same time sea water would rush eastward at a speed of several hundred metres per second, which might do damages much greater than a seaquake would do. obviously, men could hardly stand such a catastrophe.
even if such a catastrophe would not happen, there would be a great temperature difference on the two hemispheres of the earth, and the four seasons of the year would no longer occur because a day and a night would be as long as a whole year instead of 24 hours. all this would greatly affect the life of human beings, imals and plants and that would cause worse results than anything imaginable.

嘀嗒嘀嗒……原来是“音乐雨”正敲打着每户人家的“破铜”或“烂铁”。路上的行人听着“音乐雨”的乐曲，边走边听，调皮的雨又一下子变成了“魔术达人”。看，雨让快要枯死的花草和树木起死回生了，能让干旱的大地得到滋润。雨把没带伞的人们变成了一个个“落汤鸡”，这给路上的行人带来不便，住在一楼、二楼的.住户受到潮湿，更严重的话会给人们带来很大的灾难，如：水灾、海啸等，还会导致人命……。
我庆幸生于浙江，能住在浙江杭州这个美丽又安全的江南水乡。
