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.
一开始,我们一家人围坐在餐桌旁,开始互相寒暄。爸爸关切地问爷爷奶奶:“爸,妈,您们最近身体好吗?”“挺好的,不用担心。”然后爷爷奶奶就询问爸爸工作上的情况、我的学习等等。接着外公又嘱咐我说初三学习固然很紧要,但也一定要注意休息。总之,无非叙些家长里短不久,外婆和妈妈陆陆续续端来几道美味的菜,大家就又连连称赞。本来,我以为难得过节能这样一家人齐聚一堂,应该彼此有很多话想说,但谁知菜一上齐,大家就渐渐沉默了。有的开始只顾着看电视上的春晚,有的开始一心看手机新闻,最过分的是,连“吃”这一基本环节都被影响了,姑妈说:“各位稍等,请先别起筷,待我拍个照片发朋友圈。”她非但要将整桌子的菜摆成好看的形状,拍个“全家福”。还要给每一道菜都拍个特写。别人还可,两个年幼的表弟表妹可饿得等不及了,表妹撅起小嘴,抗议道:“这样光拍照,不吃,有什么意思呢?”惹得大家都乐了。
终于大家起筷,餐桌周围陷入了与春节的热闹气氛好不相衬的沉默之中。除了电视的声音,和手机的按键声,没有什么声音,偶尔有人在手机上看到有意思的新闻,说出来分享一下,也不过大家略议论几句就又安静下来了。别人没话说,表弟表妹可是非常想和大家聊天。他们不停的呼唤,餐桌旁的每一个人都喊了个遍,可是没有得到丝毫关注。最后,表弟无奈地说:“他们怎么都不理我们呢?不如我们两个一块儿玩算了。”于是两个小朋友就闷闷不乐地离开餐桌,一起到客厅玩玩具去了。
饭后,姑妈让我们上微信给她发的照片点赞。于是爸爸就找到她发的照片,给她点了赞。我看到照片旁还配了文字:“团年饭,一家人欢聚一堂,真是其乐融融!”可是,今晚大家都只顾着做自己的事情,餐桌旁缺少了应有的欢声笑语,只有尴尬的沉默,这样也能叫其乐融融吗?
餐桌前的谈话,不仅仅只是亲人之间的闲谈,更是寄托着亲人之间的爱与关怀。现在,交通条件比从前发得多,团圆已经并非难事。可是人们普遍变得更加浮躁,整天忙于做自己的事情,不懂得珍惜与家人团聚的时光,所以即使是在本该身心放松,与家人谈笑的聚餐时光,都只顾着看电视、玩手机等等,餐桌前的谈话就越来越少了。团圆的意味渐渐失去了。
一家人在餐桌前一齐吃饭,这是一幅美好的画面,而其中最美好的',便是餐桌前的谈话。我衷心希望有一天,餐桌前又总能听见温馨的谈话声。
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。
从一年级到四年级,我星期六就会去书店看书,因为妈妈星期六上班,没有时间带我,她只好把我送给书店。我看的书可多了,365夜故事,女生,公主故事大全,王子故事大全……

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!

一天晚上,爷爷奶奶和我们一家坐在饭桌前聊天。
爷爷说:“我有一个笑话,是这样的。有一辆公共汽车在路上开着,司机看见一位乘客带了三个矿泉水瓶,瓶子里装满了红彤彤的东西。过了一会儿,那个乘客下车了,可是,他并没有把三个矿泉水瓶带走。司机以为那个人是坏人,他留下的是炸弹,马上报警,说自己的车里有‘不明爆炸物’。警察一听,马上让公交车司机把车子开到野外,等他们过来。司机马上把车上的人员疏散了,把车子开到野外。不到几分钟,警察就赶到了现场,总共有一百多个呢!而且他们还派出了防爆机器人。机器人来到车子里面,拿起那一个矿泉水瓶,拧开盖子,倒出来,大家一看,并不是什么不明爆炸物,而是一些鱼生,警察哭笑不得,白白虚惊一场。他们就把剩下的鱼生带回去,分了吃。”爸爸妈妈听了哈哈大笑,就我听不懂温州话,莫名其妙。妈妈帮我翻译了一遍,我也开心地笑了。
奶奶看大家高兴,也说:“我也有一个故事要讲。有一个人,抱着一只小猫,想坐公交车,可是,车上的人都不让他上车,因为猫身上的病菌可能会传给人类。可他偏要上。正在他们争得不可开交的时候,后面来了一辆一样的公交车,人们纷纷下车转到了那辆车上。这个人发现自己已经引起公愤,抱着猫走了。这个故事告诉我们,做人不能太自私,自私的人不会有朋友。”
我们家的饭桌上,爷爷时常讲百科知识,生活故事,奶奶讲道听途说的趣事。爸爸妈妈常常提醒我,这些都是写作文的材料。我在饭桌上也学到了东西。
