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.

我们班上有许多差生,还有一些好生和差等生,我坐在好生一组里,可我却得不到100分,只有几个尖子生偶尔得到,但也不多,老师为了奖励他们,有时会发一些小奖品鼓励他们.
当我们学了"一寸光阴一寸金,寸金难买寸光阴"这句话时,才明白了时间是多么宝贵,用金子也买不到,同时老师还告诉我们,平时成绩和考试分数也跟金子一样宝贵,在关健时候,如果你丢了一分,就要花很多钱来买这一分,所以分数也是很宝贵的`.
100分,大家都渴望得到,但如果你不努力,你就是等到老,也不会等到100分的光临的,只有靠自已的努力才能取得好的成绩.

：在实际生活中，为了计数的简便，可以把一个较大的数改写成以万或亿为单位的数。改写后的数是原数的准确数。 例如把 1254300000 改写成以万做单位的数是 125430 万;改写成 以亿做单位 的数 12.543 亿。
