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.
我是一名三年级的小学生,这一个暑假过完我就是四年级的小学生了。俗话说“书是人类进步的阶梯。”我一定要利用这个暑假多读书。
我的指导老师给我推荐了一本《简爱》,这个故事讲的是一个十岁的小女孩名叫简爱。书中的这个小女孩的生活过的非常艰苦、艰难,常常吃不饱、睡不足。当我看这本书的前几章时,我就觉的这个小女孩很可怜,从小就没有父母,被送到别人家领养。而且这家人对她也不好,把她一个人锁到一间从没有人住的房间里。书中领养她的那个舅妈的孩子经常打骂她,不给她看书、玩玩具。还整天把她关在房子里,不让她出去到外面游玩。自己却跟着妈妈去坐马车到处游玩。
书中还说到那个小女孩和朴人们生病了,她舅妈就去请药济师为她们看病。而自己和孩子生病就请医生给他们看病。这是前几章书中所说的事情,让人读了就感觉这个小女孩的生活很艰苦。
后面又讲的是一位先生向小女孩的舅妈提出了把小女孩送到学校里的事情。小女孩的舅妈也同意了。到了学校小女孩的生活依然很艰难,吃不饱,睡不足。但是经过努力后她的生活变的有所好转,能吃饱睡足。她还交了一位好朋友,她的名字叫海伦。不幸的是在学校里有疾病的传染,全校有八十名学生,有四十五名被传染海伦就是其中之一。小女孩为了陪她的好朋友最后一晚违返了校规,去找她的好朋友海伦陪她睡最后一晚。当小女孩早晨睡醒时发现她在这个学校里最好的朋友消失了,她很伤心。
若说世上最纯真的事物,那一定是冰雪;若说世上最纯真的情感,那一定是亲情。
雪白的冬季,飘下了第一场大雪,无数洁净的雪花,漫天飞舞,把透明的时间扭动成漩涡,把一分一秒定格在此时。我就这样一动不动的站在风雪中,瑞雪飘零,落满了肩头,散落在发丝间,把时间裁剪成一个个精致的碎片,拼成一个冰雪的季节。我把这个破碎的冬季,拾起来,存进我的永远的记忆之中,丰富着我对冬季的理解。风,凛冽着;雪,翩舞着;我,迷惘着。也不知在雪儿的怀抱之下,是不是有新的嫩芽儿,蓄势待发,顶出全新的春季。
我半眯着眼睛,仿佛看见远处有一个人影,一脚深一脚浅的缓步而来,微胖的黑色身躯似乎承载着岁月的苍茫,带着和蔼的微笑,把我的思绪引了过去。我仔细的望去,却发现,那是不久之前因车祸而左腿受伤的妈妈,正有点力不从心的向我这里走来,可毫不在意。我站在原地,一动不动,任白雪纠缠在我的睫毛上,把视野抹得花白,模糊。她终于站在了我的面前,轻轻的掸去我衣服上挂着的白雪,抹去脸上晶莹的雪泪,这个冰雪的季节,在母亲轻柔的指缝之间掠过,也变得火热,燃烧着一颗律动的心。我粲然一笑,陷在这个爱的暖流里,两只通红的手拉着妈妈的袖口,左右淘气的摇摆,嬉笑着说:“你再让我玩一会儿罢,好不容易见到江南这样日夜不间断的飘雪,留下一个美好的记忆也不行吗。”她轻笑一声,责怪道:“我是看你在院子里站了好久,这么冷的天也不知道好好保暖,万一着凉怎么办。我只是给你拿来了一件衣服,想让你穿上,免得生病,我可没想扫你的兴呀。”我顿时愣住了,接过这件暖暖的棉衣,静静的看着妈妈蹒跚着脚步走上了楼梯,衣角被风雪翻飞起来,隐没在转角处。
我缓缓抬起头,凝望着交织旋转的雪,从无际的天穹散落下来,仿佛是母亲最美的笑,倒映在这个冰雪的季节里,被无数雪折射出最朴素的光晕,深深嵌在我的灵魂最显眼的地方,化作音符,萦绕心房,使这个冰雪的季节不再寒冷,使前方蓬勃的新春不再遥远。
一扶一梦里,一笑一首曲,一爱记一生,一世还一情。

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!
