不知是世界变了还是我变了,现在的我竟然没有一个真正的朋友,也许是我不太善于和别人深交吧!多些时间喜欢一个人,一个人静静的座在草地上“朋友”一词在渐渐离我远去,我想我现在对朋友也不抱很大的希望。其实谁不想有朋友呢!好想和他一起分享快乐和忧愁,可以像他倾诉一切,也许我注定就是一个人走完高中生活之旅吧!真的好无奈哦!
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.

潘多拉盒里唯一留下的东西,现在也许被释放出来了,要不然为什么现在人人都会用它呢!但好多人的用法真的不合实际“我希望上帝赐予我金钱和权利”“我希望我的成绩是最好的”“我希望我可以和超人一样天生神力”天哪!这些都是人类的'希望,只知道座在家里等,却不自己去努力实现,难道人们不知道希望+努力=实现吗?空有希望只是竹篮打水一场空,所以我们要的更多的是努力而不是希望!
