认知地震敬畏生命作文800字

全文共 880 字

+ 加入清单

沉睡的山脉伸了一个懒腰,时间的秩序顿时乱了套。大地吞噬,泥水洪流,悲伤已成定局。我们熟读了物竞天择的自然生存法则,懂得适应物竞的血腥,忧伤弥漫。伤痕刻在心底,痛苦无从分担。光阴的河道里,冲刷的伤口已经泛白。时空交错验证着“消失比在场更恒久,执着之后终要放手”的真理。

地震是地球上主要的自然灾害之一。是世界上最凶恶的敌人,它对社会会造成一系列的直接灾害。建筑物与构筑物的破坏,桥梁的断落,铁轨的变形,对经济建设造成巨大的打击。同时,地面破坏坍塌,对地表破坏也巨大。它对自然物也会有所破坏,海啸、海底地震引起的巨大海浪冲上海岸,造成沿海地区的破坏,并且会引发次生灾害。有时,次生灾害所造成的伤之比直接灾害还大。如火灾、水灾、毒气泄漏甚至是瘟疫,对人类的灾害是不可估计的。

从1976年的唐山地震到2008年汶川地震,我们经历了许多生离死别,天塌地陷,山河地碎。死亡,伤痛取代了绿肥红瘦,泪水侵湿的日历记录着我们的国殇!震后的岁月,是一个见证,是一个记载!见证和记载中国人勇敢、坚韧、博爱,团结的奋斗历程。它见证和记载了以人为本理念在现代社会生活中的拓展。救援行动演绎了人的生命高于一切,先于一切,忠于一切的理念。它见证了记载了中华民族巨大的凝聚力。

灾难可以毁灭一切物质,却无法摧毁人的意志。

面对触目惊心的荒凉,惊吓与沉沦只会使我们瘫软在地。何不抛弃我们对命运的不满之情,启动生命储藏的全部力量奋力一跃?生命质量的高低取决于心灵世界的强弱,一颗强大的心灵在任何的险境中都能找到应对的方法。珍惜所拥有的,调节好自我,珍惜这场灾难所馈赠给我的最大“礼物”。

生命就像大海中的一叶扁舟,漂浮不定,四海为家。人生又何尝不是如此呢?刹那芳华,红颜弹指老,人生如梦,醒时万事空,人生如那精美的陶瓷花瓶,不知道什么时候无意地轻轻一碰,便会哗啦啦地碎了一地。拥有生命,我们才有了希望,生活便有了更多的激情,我们要认真面对生命中的每一分钟,这样我们的年华才不会虚度,就让我们在未碎之前,尽情地展示我们最美的风姿吧!以一个最佳的姿态去面对命运之神赋予我们一切的悲欢。

热爱生命,做生活的强者!

Good brother,

It has been some time since I read your letter. Have seen many times, in

the mind also has a lot of words to say, but... I never knew where to start. On

this Christmas Eve night, let me start with memories.

Dude, Im not a pushy girl. In your eyes, I am the little sister in your

memory. I am the single woman who was alone in a foreign country, weak in heart

but strong to face life. At that time, I was alone in the face of difficulties

in other countries, alone for life, simply for survival and struggle. At that

time, I had to be strong. Since my childhood, I have been a happy, carefree girl

around my parents. During those years in a foreign country, stress and

loneliness made me grow up. However, I am still not strong.

Eldest brother, I have benefited a lot from the four years suffering

abroad. I have learned a lot and grown up a lot. Maybe it is gods reward for

me. After coming back to China, my career, life, smooth and peaceful for a few

years. However, I am still lonely, many times, the heart is very bitter very

bitter, as when writing this letter, alone. The tears would flow when I

remembered the things I had buried in my heart.

Brother, I, too, want company. Want to take a persons hand, walk together

after the day, face this complex world together. Just want to be a little woman,

can take a persons hand, a person can be heart to heart, from now on, no matter

what things, all to face together.

These years, and brother has been out of touch. Always remember you once

said a sentence. Friends, is in the heart, no matter how no contact, no meeting.

But in my heart, I always remember having such a friend. Your love and care has

always been in my heart. I havent talked to you in depth for a long time, so

Ill go on.

The reason I have remained alone all these years is not because of the

conditions I set for my partner. I want a person, actually very simple. Ha ha,

big brother, dont laugh at me. I just want a little love.

In this day and age, all people will tell me that nothing is more illusory

than love. But I, still stubbornly looking forward to, there is a warm, real

person can appear.

I, however, is an ordinary woman, but also just want to live an ordinary

day. Fall in love with someone, then face life with him, work hard for the

future together, raise a child together.

Several times during the blind date, the plain man sitting opposite asked

me, what do you want from the man. A house? Income? Or a car. Can face such a

problem, I always cant speak, only smile, the heart of despair and pain began

to spread...

Brother, I am just a woman with a strong exterior and a soft heart. So,

now, what kind of person do you think I should accept at the time of blind date?

Im not asking for a strong man, as you say. I just want a gentle, understand

life, know love, know how to cherish people.

Life is short. You can let yourself, and live for yourself is even shorter.

But sometimes also want to do not cooperate with their parents so unfilial, will

also think, perhaps, marriage is a can not be so selfish thing, even if it is to

comfort their parents, also should let their marriage as soon as possible.

Xi an, the city we live in now. Old and elegant. Is the home that has been

on my mind when I was a vagabond. In the next year, I will continue to live in

this city in a down-to-earth way. I hope that there will be one person who can

fall in love with each other in a down-to-earth way. This is a Wish made on

Christmas Eve.

Miss ~ ~

In the twinkling of an eye, 2017 has gone quietly, and the steed of 2018

has stepped forward. All the past is memories, and the future is beautiful!

Throughout 2017, yianju foremen club has contacted thousands of owners

with decoration needs, constantly participating in and listening to your

decoration stories. Maybe some of our owners did not reach an agreement in a

short period of time, so they withdrew from your decoration stage. However, this

does not hinder yianju from sending you warm wishes for the new year and

keeping the same new house as you Happy mood; more owners have completed the

decoration tour of your home with the efforts of the eXcellent foremen of yianju

foremen club and the witness of yianju staff, which certainly contains

heartache, anger, joy and eXcitement. Of course, it is inseparable from your

hard work. Do you remember that our company staff asked the boss for leave to

facilitate you to go out and buy building materials? Do you still remember that

while you were out on business, you secretly went to the new house to "inspect"

the workers construction? Do you still remember that you were fined a days

salary because you didnt choose a suitable living room lamp for a whole

afternoon? Do you remember the quality problems and construction delay caused by

the workers disobedience and in accordance with his so-called "eXperience"? How

angry and mad you are! Ha ha, its all over. It doesnt matter. Whats important

is that your new residence has become better and better in various coordination

and communication, and has become the same as you imagine. All kinds of

happiness and unhappiness in the past 2-3 months have become memories, an

irreplaceable memory. In the future life, in which details, you will more or

less think of these eXperiences Will smile gently.

With your strong support, yianju foreman club has gradually completed the

transformation from ordinary decoration company to foreman club mode, adapting

to the home decoration mode of low gross profit and high output. While

maintaining good construction quality, it really gives the profit to the owner

and the foreman.

In this year, we also encountered the refusal to pay labor fees by

unscrupulous customers, many customers were "unconditionally" deleted in the

public comments, and malicious competition from peers... But fortunately, we

still have your support, so we have not stopped moving forward, which is better

than the special inspection mechanism of other companies, the proXimity

principle of convenient site management, and the home insurance given to

customers ... all this will only make us go better and farther! Because,

everything has you!

In the new year of 2018, the development principle of easygoing is still to

make profits, so as to benefit the decoration owners and the construction

foreman; to carry out practical decoration, it is really developing!

On the eve of Chinese traditional New Years Eve and Spring Festival, all

the staff and foremen of yianju foremens Club wish you and your family a happy

New Year! Happy family! Everything goes well!

在汶川地震的这些天,我看到许许多多感人肺腑的事,但始终忘不了的是许多老师无私奉献的精神。

地震后,张米亚老师的名字被大家深深的记住,他是汶川县一个镇的老师,地震发生的时候,他双手死死护住了两名学生,宛如一只展翅的雄鹰,在他的保护下,两名学生都成功获救,他却永远的闭上了眼睛,让人心痛的是,在救援人员救援的时候,张米亚老师紧紧护着怀里的两个学生,胳膊怎么都掰不开,救援人员只能忍痛割去了张米亚老师的双臂,才把两名学生救了出来。

地震无情,人有情,一场8.0级的大地震,让无私无畏的人间大诠释的淋漓尽致,他们用生命谱写的人间大爱将延伸到宇宙的每一个角落!(指导老师:李纪伟)

今天下午,我们观看了防火灾知识,为我们讲解的是候教官,他的讲解,让我深有感悟!

下午的时候,我们观看了防火灾的知识,候将官为我们讲解的非常的详细。我们看到了候教官说,一般发生火灾的时候,我们要弯腰,低头,在拿一个叠了三次的毛巾捂住口鼻,(毛巾要是湿的,而且要轻轻的拧一下)。

看了候教官的讲解,我有很深的感受:原来防火的要求是这么的多呀!以前的时候,我以为火灾非常的简单,就是发生火灾的时候拿一个湿毛巾冲出去,而并不知道湿的毛巾还要轻轻地拧一拧,也不知道要用叠了三层的毛巾来捂住口鼻,还不知道逃生的时候要弯腰,低头,离地面的距离还是三公分,所以看了这次的讲解以后深有感悟。

我还懂得了,来到了每一个超市的时候,要观察逃生出口在哪里,到时候,万一找了火了,可以很快的找到逃生地点。还有,我们的车里面一定要装有灭火器,和一个可以杂碎玻璃的小锤子,而这些东西还要时时刻刻的放在自己的身边才行!

通过这次候教官的讲解,我对火灾逃生有了充分的认识,和知识!

离开学还有几天的时候,我和妈妈、妹妹一起回姥姥家,去看望姥姥,也顺便住几天。

坐在大巴车上,等待这漫长的两个小时,终于到姥姥家啦!我下车就跑,一边跑一边喊:“姥姥、姥姥我们回来啦!”快到门口时,我隐隐约约地听到小舅妈的声音,“你快点去看看,好像是她俩回来了。”我和表姐差点撞头,她出门迎接我们,而我是慌着回家,就这样,我们俩个撞在了一起。

到了下午凉快的时候,妈妈领着我们几个一起去田边玩耍,在路上走着走,妹妹突然说:“妈妈,咱们去那边的草坪上玩吧!”妹妹的话音刚落,表姐和表弟大笑起来,他俩异口同声的问:“你说那是什么?”妹妹说:“草坪啊!”“你是真傻还是装傻啊,那是花生地,可不是你们城里的草坪。”妹妹觉得十分尴尬,还有点害羞,妈妈说:“你俩别笑话她了,因为她们没有见过农田里的东西。”也是啊,我们从小生活在城市里生活,对农田的植物基本上一概不知。

我们又来到一片绿油油地方,我说:“妈妈,这个是荆芥吗?”话音刚落,那俩讨厌的姐弟俩又开始嘲笑起来了,他俩哈哈哈大笑,说:“那是芝麻啊。”妈妈怕我和妹妹伤心,然后就说:“你们俩呀别再笑她俩了,她俩呀,就像“银环”第一次下乡一样,哪见过这些东西呀!”妈妈的话音刚落,我就问:“妈妈,银环是谁呀?”妈妈说:“银环是豫剧《朝阳沟》里的人物啊!”妈妈又对我说:“你走近点仔细观察一下,看看荆芥和芝麻有什么不一样。”哦!我又仔细看了看,果然有点不太一样,猛一看非常相似,但是它们的叶子有些不同,荆芥的叶子看起来细腻发亮,是翠绿色,芝麻的叶子看起来粗糙,而且是暗绿色。就这样,妈妈又领着我们一起认了很多的农作物:花生、玉米、大豆、高粱、谷子……

就这样一下午在田边闹了不少笑话,但是这让我长了不少见识,真是一个收获了很多的下午啊!

小时候的我,在“锄禾日当午,汗滴禾下土”的诗歌中长大。我很喜欢古诗,但就不喜欢看一些其他有用的书。因此我拿着书看一两分钟不到就烦,看书是我最讨厌的事了。

然后,我就真的喜欢上了看书,作文也写好了。玩什么看图猜成语、成语接龙也很厉害了。

篇13:地震科普携手同行

还记得那日的四川本是风和日丽、阳光明媚、鸟语花香、生机勃勃,然而却在那一瞬间,8级强震猝然袭来,大地颤抖、山河错位、满目疮痍、生离死别,西南处,国有殇!这是新中国成立以来破坏性最强、波及范围最大的一次地震。地震重创约50万平方公里的中国大地!

截止2009年4月25日10时,遇难人,受伤人,失踪人,其中四川省名同胞遇难名同胞失踪,共有5355名学生遇难或失踪。直接经济损失约达8451亿元。这是中华人民共和国成立以来影响最大的一次地震。

于此可见地震带给我们的危害是巨大的,而地震是自然灾害,是无法避免的,是我们人类最大的敌人。虽然我们无法避免,但是随着社会的发展,我们应该懂得用科学的道理,使用的办法来保护自己,减少灾害,避免威胁到自己的生命。下面我们一起了解如何用科学的方法来防震减灾,保护自己,保护家园。

地震来临前,地下水,动物都会有一些异常。只要我们用心观察就会发现地下水冒泡、发浑、变味等。而动物则是乱蹦乱跳、惊恐不安等,这些都是地震来临前的征兆。在地震来临前,我们要掌握防震减灾知识,提高自我保护意识;明确地震时疏散路线和避震场所;清楚楼道和门前杂物;妥善处置屋内易燃易爆物品,关闭煤气,切断电源,熄灭炉子火等;衣袋里装上家庭成员名单、工作单位、通讯密码等;有确切的要写明血型。

地震发生时,从地震开始到房屋倒塌,一般有12秒钟,此时要保持冷静,要做到以下几点:

能撤离时,迅速有序地疏散到选定的安全地区,不要拥挤在楼梯和过道上。

来不及撤离,应就近避震,震后再迅速到安全地方。例如:在家里可躲在床或书桌下面或较小的房间,如卫生间。在教室可躲在书桌下或墙角边。在影剧院和饭店可躲在椅子下。

撤离到室外或正在室外的人员要选择空旷地带避难。

避震时要注意保护头部,如枕头、脸盆、书包等顶在头顶,或用双手护住头部。

地震发生后,大地震中被倒塌建筑物压埋的人,只要神志清醒,都应该坚定获救的信心,妥善保护好自己,积极实施自救。

我相信如果每个人都能做到,那我们在灾难面前便显得不再是那么渺小,在灾难面前绝不再低头。防震减灾,共创美好家园!

篇14:科学小知识作文800字

科学可以告诉我们很多知识,如果你想明白其中的奥妙还需自己动手做实验,也可以找“百度”来帮帮忙。

这个星期天,我早早地做完了回家作业,和爸爸一起看着有关特务类的电影。忽然出现的一个场景引起我的好奇心。电影里的一个特务手里拿着一根棉签,再用柠檬挤出一盘子的柠檬汁,再用棉签蘸着柠檬汁在纸上写着字。我猜想纸上的字一定是情报。可是,等到纸干了,字也随着消失了。接着就是收情报的演员,他接过情报用打火机在纸上慢慢的烧着,不一会儿,纸上的字就又显示出来了。我指着电视上的情景不解的问爸爸:“爸爸,这是怎么回事,字为什么会不见了呢?”

爸爸摇了摇头道:“这个我也不知道。”

“不过,你可以自己做一个跟他一模一样的实验,或许就知道了其中的奥秘。”

“嗯,那好吧。”我听了爸爸的话,开始准备着材料。

不一会儿,材料就准备好了有:一碗柠檬汁、一根棉签、一张干净的白纸和一个打火机。

我学着电视里的特务,用蘸过柠檬汁的棉签在纸上写满了密密麻麻的字,放在桌子上晾干,大约过了一两分钟,字就干了。我再拿出打火机在纸的底部用打火机烧,不一会儿纸上消失的字真的就又能看见了。我大声的叫道:“OMG,好神奇呀!”

可这是为什么呢?我百思不得其解,最后还是决定问一下“百度”。

百度上是这样告诉我的:纸内含有的淀粉,会与碘产生化学反应形成碘淀粉分子,而呈现深蓝紫色;而柠檬汁中含有丰富的维生素C,当维生素C与碘产生化学反应时,会产生无色的现象。因此以柠檬汁写字或画图的部分不会有颜色改变。

因为柠檬汁中含有一种叫赛璐酚的成分把它写在纸上,可以降低纸的燃点,只要用火一烤,柠檬汁写字的部分最先被烤焦,呈现黄色的字就能显现出来了。

这让我又想到了另外一个电影:一个小特务,每天都会在街上卖鸡蛋,而且买鸡蛋的人总是那几个,我发现原来鸡蛋里是有情报的,因为小特务用笔蘸着醋在鸡蛋壳上写字,可是当鸡蛋一煮熟,字就会在蛋白的表面,这样情报就不会被发现了。

通过这两件事例让我更加爱上了科学,更加喜欢科学,也让我明白了原来大自然和生活中就能发现很多的科学小知识。

今年9月1日,在学校的组织下,我观看了《开学第一课》,其中解海龙关于梦想的一番演讲,使我受益匪浅。

早期的解海龙虽然在摄影方面获得许多奖项,但还是迷茫的。自从他看到《九年义务教育法》颁布后,他为自己定了一个目标,一定要帮助贫困山区的孩子们。苏明娟,有着一双炯炯有神的大眼睛,眼神里散发出求知若渴的欲望,“小光头”张天义、“大鼻涕”胡善辉,都是渴望得到知识的孩子,而由于贫困,条件艰苦,求学困难。解海龙老师拍照后,这些孩子得到社会资助,顺利完成学业,找到满意的工作,改变了自己的命运。其中的“大眼睛”苏明娟,成为希望工程的代表图片,解海龙老师也一举成名,也实现了自己的目标。

他们的经历验证了一句话,“知识改变命运”。我们年轻的一代,也要用知识武装自己的头脑。

就从我本人讲吧!小时候,我在老家河南生活,学知识并不是很多,又不懂得讲普通话,常常被人笑话。从那一刻起,我便下定决心,一定要学习更多的知识,白天努力学习,晚上的努力阅读,我的成绩逐渐呈上升趋势,刻苦练习也造就了一口流利的普通话。现在我小学六年级,我的背后不再是无限的讽刺,而是别人对我的赞叹,我逐渐明白“知识改变命运”的含义了。而我的亲身经历也在对我说知识可以改变命运。虽然现在我还小,但是我相信只要努力学习,幸福的生活就会离你不远了。

知识改变命运,身边的人诸多事例都在向我们展示知识一定改变命运,让我们努力学习知识,用自己的本领报效祖国。

"文学常识"包括:中国重要作家的时代及其代表作,外国重要作家的国别及代表作,文学体裁常识。

"重要的作家及代表作"是指在中外文学史上,有重大影响的作家、作品。这些著名的作家、作品,是毕业生应该掌握的。"文学体裁"主要指的是文学四分法所说的诗歌、小戏剧、散文四种体裁。

文学常识这部分的内容,知识性强,学习方法主要以记忆为主,但从命题的主旨看,并未提倡死记硬背,主要考查学生在掌握知识的基础上,能运用已掌握的知识来分析问题、解决问题。

就试题的内容看,往往是综合性的,覆盖面大,如果没有这方面的系统知识,要想学好是不容易的。这就要求要牢固掌握这方面的系统知识,在复习的方法上,应当以文学史为纲来复习记忆。

前几天,我妈妈带我去买书,买了许多书后,我忽然看见一本《三国故事》,我兴高采烈地把这本书放到了袋子里,准备回家仔细看看。

回到家,我二话没说,飞快地把《三国故事》给拿出来了。我看了看目录,第一章是黄巾起义、第二章是子全父义,第三章是登城先入、第四章是……我看了看第一章,主要讲的是黄巾军是怎样成立的、黄巾军的领导是谁和黄巾军是为什么以前打过那么多胜仗而这次却被永远地消灭了。

没过几天这本书我就已经大约看了半本了,关于三国的知识我也了解了许多,一有关于三国的题呀,作文呀,我都对答如流,最近爸爸也觉得奇怪,就把我叫了过来,问:“你最近怎么回事,三国方面有了很大的进步啊?”“我只不过是把那本《三国故事》上的重点知识记下来罢了,活学活用嘛。”我不好意思地说。

一本小小的课外书,却给我带来了丰富的知识和巨大欢乐。

研学游不是指的那种“旅游”,而是去一些地方参观,多多的提高我们的知识

今天,我们去研学游了,这是第一次,而对我们来说这是最后一次,校长为我准备了水和营养餐,我们就坐上大巴车出发了。

第一站是:生态潜流基地,讲解员对我们说:“化工场排出的水很容易污染河流,可里这不一样,看!我们的南面是化工场,北一面是过滤基地,化工场排出的污水会经过地下管道,到达过滤基地,经过过滤,就变成和河水一样的水了。”

我们转了一大圈,又去了过滤基地转了一圈,真是大开眼界。

之后又去了蔬菜基地,到那里看到了黄瓜、西瓜、西红柿,长的都非常的好,可是刚到蔬菜基地,没走几步,马中岳,就因为晕车,吐了,他吃完药后,又回来了,因为就这一次,他不想走。

之后,我们又去了,植物园,在那里我懂得了稼接。

然后,我们有去了,寅寺镇中心幼儿园,幼儿园都要比我们学校大,进去之后那些童年的玩具唤醒了我的讵忆,我们正玩的不亦乐乎时,便开始吃饭了,我们吃完饭后,我们去玩了一会儿,便去下一个地点了。

寅寺镇中学是我们的最后一个地点,我们先去了图书楼休息了一下,便去了办公木娄,整个办公楼的墙上写的全是党的发展历史,我记忆最深的是社会主义核心价值观:富强、民主、文明、和谐、自由、平等、公正、法治、爱国、敬业、诚信、友善。

这次研学游我懂得了“不忘初心,牢记历史”。
