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.

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!
又到吃饭的时候了,桌上摆着新鲜的白灼虾,诱人的红烧肉,绿油油的小青菜,还有一大锅炖了好久的排骨汤,真是荤素搭配,营养丰富,一看就是外公外婆精心为我准备的。外婆在一边不停地对我说“多吃点虾,长高个,喝点排骨汤,补钙的,再吃点蔬菜,补充维C……”哎,我一直对大人们这种“填鸭”式喂养有意见,我看着满桌丰盛的菜肴一点胃口也没有,慢吞吞地嚼着饭,满脑子里只有牛排汉堡。外公看我一副不乐意的样子,不高兴地说:“你这孩子真是身在福中不知福,***妈在你这么大的时候,不管买什么东西都要凭票,买肉要肉票,买米要粮票……全是由国家统一分配,想多买些肉都不行。 ”“是啊!是啊!”爸爸也在一边接着说,“如果我小时候天天有鸡蛋吃牛奶喝,我还会长得更高些!”一直没开口的妈妈说话了,“吃饭的时候别教育孩子,会消化不良的。”还是妈妈好啊!可我又听到妈妈接着说“赵怡霖,多吃点,你看你瘦得……”看着四个大人围着我,四张嘴说个不停,我只好一声不吭,谁叫我长得像根小豆芽菜呢?他们也是为了我有个好身体,想给我增加营养啊!哎,这就是我们家,每次吃饭最后都变成了忆苦思甜。不过,我觉得他们说得也有道理,我们现在的生活确实像掉进了蜜罐里,我也十分庆幸,我生活在幸运的年代,能过着幸福的生活。外公这个老党员曾告诉我:“这都是党的功劳!” 是党,让我们的生活更美好!如果把党比作阳光,那我们就是花儿,花儿在阳光下茁壮生长,我们在党的关怀下幸福成长。我们要像花儿吸取养料一样,不断汲取知识,学好本领,将来报效祖国。我坚信,在我们不懈的努力下,祖国的明天会更美好!
要说在本学期内我最喜爱的一本书,那自然是《简·爱》喽。
自从学了《小草和大树》这篇课文后,我就对从逆境中成长的夏洛蒂·勃朗特写的《简·爱》着迷起来。
小说中的简·爱出生于一个穷牧师家庭,在她很小的时候,父母由于染上伤寒,在一个月内相继去世。年幼的简寄养在舅妈家里,受尽歧视和瘧待。后来,简被送进劳渥德孤儿院。孤儿院教规严厉、生活艰苦,她在那里接受了八年的教育。
从孤儿院出来后,简到桑菲尔德庄园做家庭教师,并与主人罗切斯特相爱了。他们在教堂举行婚礼,可是婚礼当天,她才知道罗切斯特多年前已经结婚。法律阻碍了他们的爱情,使两人陷入了深深的痛苦之中。
在一个凄风苦雨之夜,简离开了罗切斯特。后来桑菲尔德庄园在一场大火中烧成废墟,纵火的疯女人坠楼身亡,罗切斯特也受伤并残疾。简·爱受尽磨难,最后原谅了罗切斯特,并与他结了婚,过上了幸福的生活。
这本书里的情节时常让我潸然泪下,对简·爱报以深深的同情。夏洛蒂·勃朗特和简·爱一样,都是在受尽磨难后依靠坚强的意志昂首挺胸。可以看出她们的人生主张一爱与尊严,两者缺一不可。
人生的道路是坎坷的,只有你有强大的信念、刚强坚韧的内心和坚持不懈的努力,才能通向幸福的大门。这是这本书告诉我的道理。
