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.
你们好!
孩子是父母的牵挂。每位家长都希望自己的孩子能够接受优质的学前教育,健康成长,为一生发展奠定良好的基础。幼儿园教育是基础教育的基础,是为孩子终身发展和一生幸福奠基的教育。幼儿园通过让孩子在集体环境中,在游戏化的活动中,养成良好习惯,培育良好品质,发展智力。家庭和幼儿园应该携手,围绕科学的保教理念,密切配合,保护儿童身心健康快乐成长。
对幼儿要开展以游戏为主的学前教育,不得进行“小学化”的教育。我们幼儿园要遵守和落实这个规定,建议家长也要积极响应和配合。幼儿教育“小学化”是影响幼儿生理和心理健康的重要因素,直接导致孩子手指变形,书写姿势不正确,,到小学后普遍出现厌学,注意力不集中,发展后劲小等,影响孩子正常发展。幼儿园要以游戏为基本活动,实施科学保教,就必须提高教师的专业素养,创设环境,加大户外游戏活动和区角活动的力度,把游戏融入一日活动之中,在游戏中发展幼儿的智力,培养幼儿的学习兴趣和良好的生活、学习习惯。
幼儿教育是一个系统工程,由幼儿园、家庭、社会三个方面共同组成,三者必须密切配合,形成合力,才能更好促进幼儿身心健康发展。那么,尊敬的家长朋友,让我们一道树立正确的`育儿观,以积极合作的态度理解、支持、配合幼儿园的科学保教工作,规范教育行为,对孩子实施科学的幼儿教育,自觉抵制小学化不良教育行为,促进幼儿身心健康和谐发展,使今天的“幼苗”明天能够长成参天大树!
最后,衷心感谢各位家长对幼儿园工作的理解与支持,并祝愿孩子健康快成长!

Recently, there is a popular saying: the world is so large that I want to have a look! As more and more people travel around during their holidays, tourists have brought large sum of money to the local people.
However, too many tourists also bring some problems to the local life. The most serious problem is the pollution caused by the uncivilized tourists. It’s reported that there were thousands of tons of rubbish left after the flag-raising ceremony on Oct. 1st. The uncivilized tourists left their rubbish wherever they go, polluting the local environment. Another problem is the traffic jam caused by so many tourists.
Tourist can promote the economic development of the local areas, but the pollution caused by those uncivilized tourists has brought severe problems. The local tourist authority should set up relative laws to protect the environment of the local areas, and every tourist obey the laws and help to make the places of tourist more beautiful!
