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!
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。
我小心翼翼的走上山,到了半山腰,我看见一棵非常古老的大树,它有几百年历史了,根深深地扎进泥土里,地上的落叶很多,一踩上去,脆脆的声音马上响起。我拾起一片落叶,仔细地看着落叶上精致的纹理,我看到了它蕴含的生命的奥秘。突然,我自己也慢慢地变得“瘦”了下去,变得只有一毫米厚了,自己的头发变成了落叶的根,自己的脚变成了叶尖。
这山中的一切,哪个不是我的好朋友?我热切地跟他们打招呼:你好,温柔的微风!你轻轻地吹出一口气,是想帮我飞得更高吗?您好,大叔爷爷!您的子孙在您的手上生活得多满足啊。你好,翠绿的小草!你站在最低的地方仰望着庞大的世界,却从不抱怨。你好,淘气的云雀!你们用清脆的声音歌唱着,是希望我来当伴舞吗?我的身子轻飘飘的,一会儿上到更高的地方,一会儿又降下来,一会儿飘到树林中,一会儿又飘到草地上。
微风姐姐飘到我的身边,她呼了口气,我又缓缓地升高,升高,没有翅膀的.我,却好好的体验了一回飞的感觉。我虽然只能随着微风飘到任何地方,但我觉得我是自由自在,无拘无束的。我一会儿低下头欣赏美丽的大自然;一会儿又翻个身,把微风当床一样享受的躺着玩;一会儿又抬起头看着似乎触手可及的天空。
我降落在一片树林中,这片树林清新而广阔。微风吹着气,我随微风跳起了欢快的舞蹈,像是在欢迎着我的到来。小小的虫子,爬上高高的树叶,做忠实的听众和观众。我开心的望着他们,开始踮起脚,转个身......半小时就这样过去了,这场隆重且盛大的欢迎会,谢幕了。
山中的麻雀在呼唤着我的名字,我才回过神来,匆忙和大树挥手后,跑下山了。
家乡的山峰峦叠翠,草丛,树木,苍翠欲滴。每个经过这儿的人都会沉醉在这清新然或云雾缭绕的境界中,这样的境界,诗书画般的境界。

对于爱情我并不懂得,我也不喜欢看一些爱情片,理由很简单因为我不知道什么叫爱,曾有处于恋爱中的朋友问我:“你知道什么叫爱吗?你相信爱的永恒吗?『我无言以对,只因为我不懂得什么是爱,初二时曾有一个男生对我说他爱我,可我问他你为什么爱我,你知道什么是爱吗?他沉默了,这么多年我一直不知道什么是爱,也好想知道可没有一个人知道。我在贻一本书里看到过这样一句话“想信爱是永恒的,只要你用心寻找你会得到属于你的真爱,但不要相信吻你是睁着眼睛的恋人,因为在他心里还有起他人!”
也许着就是爱情吧!不让你知道,不让你了解,只要你的真心便可寻得!
