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.

现在中国流传着一个非常可怕的病，这个病的名字就叫做H7N9禽流感，中国目前确诊109例感染者，其中22人死亡。人们因为这件事再也不敢吃鸡蛋、鸡、鸽子……
其实H7N9禽流感病毒并没有我们想象的那么可怕，因为禽流感可防、可控、可治。
禽流感期间，多吃蟹味菇、白玉菇等食用菌类!因为菇类除了具有蔬菜拥有的维生素，矿物质和纤维素外，还含有2。7%的植物蛋白质和20多种氨基酸，是最接近肉类的蔬菜品种。更重要的是蟹味菇、白玉菇等高端食用菌具有抗病毒提高免疫力的功效!
发现疫情时，应尽量避免与禽类接触，对鸡肉等食物应彻底煮熟;保持室内空气流通，尽量少去空气不流通场所;注意个人卫生，打喷嚏或咳嗽时掩住口鼻。H7N9是家禽、飞禽中传播的一种病毒性传染病，截止今天，我国发现的60个病例都是直接来自于禽类的传播，还没有发现人与人之间的传播。鉴于此，预防此病的主要手段就是截断病禽与人的接触。北京发现的一例是家禽饲养户，上海发现的病例均有病禽接触史。
所以只要我们按照上面的建议去做，就会离H7N9远远的，所以禽流感并不可怕，因为它可防、可控、可治。
