The Thirsty Dog
A dog is very thirsty. But he only sees some empty pails. There is no water in them. The dog goes on looking for water. He comes to a small house. There is a girl in it. The girl goes out with a pail. “She goes to a well,” the dog thinks and follows her. The dog is right. The girl comes to a well and puts down the pail, and the pail is full of water, there the girl goes back to her house.
“Water! Great!” the dog says and runs to the well. He jumps into the well without thought.”
The water is good. The dog is happy and drinks much. But he can’t jump out of the well. He waits and waits. But no one comes. “I’m hungry now. I must go out,” he thinks.
At the time a thirsty goat comes to the well. He looks at the water and the dog. “Is he water good?” the goat asks. “Of course. Come down,” the dog says. Then the goat jumps into the well, too. Then dog is happy. He jumps on the goat’s back and jumps out of the well.
The dog has a look at the goat and says, “Goodbye!” Then he leaves.
一只口渴的狗
有一只狗口很渴,他只找到一些空空的水桶,里面没有水。他继续找水。他来到一座小房子前面。房子里住着一个小姑娘。小姑娘拎着只水桶出来了。 “她要去打水。”狗想道,并跟在她后面。果然不错,小姑娘来到一口井边,把水桶放入井里,水桶水满了。然后小姑娘回去了。
“水!太好了!”狗叫着跑过去。他想也没想就跳下井去了。
井水真的不错。狗可高兴了。喝了许多水,但是他没有办法跳出来了。他等了好久,但是没有人来。 “我饿了,我得出去。”他想着。
这时候一只口渴的山羊到井边来了,他看了看井水和这只狗。“这水好和吗?”山羊问狗:“当然了。快下来吧。“狗回答说。于是山羊也跳到井里了。狗高兴极了。他跳上山羊的背,又跳出了水井。 狗看了一眼山羊说声:“再见。”就跑开了。

Dear teachers, dear students:
hello everyone!
The topic of my speech is "the hardness of life"
The vast desert, a tree stand, the show is a monument to the image.
Towering mountains, thousands of tree stand up, as is a magnificent the Great Wall.
The long river, all the trees stood up into a dragon of glory.
#p#副标题#e#
We are a symbol of too much, and too much. But I believe that my image is not "the gentlest hands, skin, such as Diorskin" Lin Daiyu, nor is the modern "unkempt and shabby", "Su Qier". We are a symbol of hope and vitality. So we show in front of others should be inserted without pleats, face without scale, modest and polite gestures exudes a stream of heroic spirit, the image of the vigor and vitality of the modern new youth, a into the embodiment of the spirit of nature.
Someone once said, life is a kind of hardness, integrity and dignity of life is propped up the hardness of bone. "Better life" and "the Kui back in the day, and not ashamed on the ground", which is always the traditional virtue of the China. Li Bai's "the eyebrow nengcui Zheyaoshan powerful thing, so that I may not be happy Yan" this awe inspiring atmosphere of the verse and whether it will make those no self-esteem people to shame? Loss of self-esteem is a worthless person, and we as the vanguard of the times, if drown in the darkness forever, or to do a dauntless hero, a flower in the wind and rain sonorous rose. The answer is self-evident.
Desert desolate also has the monument stands, Castle Peak again proud, but also have the great wall around, the river again quiet, also there is a dragon in the recumbent. But the time can be changed, our image, our glory remains the same. Because we pride, because we are confident, because we have a fresh life. And because of this, it is a vast desert riparian long, Qingshan was evergreen, the hardness of life is forever.
尊敬的各位老师,亲爱的同学们:
大家好!
我演讲的题目是《生命的硬度》
茫茫大漠,一棵树站不起来,展现出来的是一座丰碑的形象。
巍巍青山,千万棵树站起来,连成的是一条长城的宏伟。
悠悠河岸,所有的树站起来,缀成的是一条蛟龙的雄风。
我们象征着太多,又演绎着太多。但我相信,我的形象,绝不是“手若柔荑,肤如凝脂”的林黛玉,也绝不是“蓬头垢面、衣衫褴褛”的现代“苏乞儿”。我们象征着希望、朝气。所以我们展现在别人面前的就应该是衣无褶、脸无垢、礼貌谦和的举手投足间散发着一股英气,朝气和活力的现代新青年的形象,一个融入了大自然的精灵的化身。
有人曾说,生命有一种硬度,气节和尊严是撑起生命硬度的骨骼。“宁为玉碎,不为瓦全”、“仰不愧于天,俯不怍于地”,这是历来中国的传统美德。李白的“安能摧眉折腰事权贵,使我不得开心颜”这一大气凛然的诗句又是否会让那些毫无自尊的人汗颜?丧失了自尊的人是一个没出息的人,而我们作为时代的先锋,要是永远在黑暗中沉溺呢,还是要做一个顶天立地的好男儿,一朵绽放在风雨中的铿锵玫瑰。答案,不言而喻。
大漠再荒凉也有丰碑的矗立,青山再孤高,也有长城的环绕,河水再平静,也有蛟龙的横卧。而时代再怎么变,我们的形象,我们的雄风依然如故。因为我们自尊,因为我们自信,因为我们有着鲜活的生命。而正因如此,河岸才悠悠,大漠才广袤,青山才长青,生命的硬度才长存。

英语演讲是每个学生都需要拓展的技能。读文网小编为大家整理了中学生英语演讲稿大全,欢迎大家阅读。
In my 18 years of life, there have been many things. University days are the best part of them. I can never forget the days when I stepped into my university. I was impressed by its garden-like campus, its enthusiastic students and especially its learning atmosphere. I at once fell in love with it.
After the arduous military training, I get absolutely absorbed in my studies. The classes given by the teachers are excellent. They provide us with information not only from our textbooks but from many other sources as well. They easily arouse my insatiable desire to take in as much as I can.
Frankly speaking, at first I had some difficulty following the teachers. However, through my own efforts and thanks to my teachers' guidance, I made remarkable progress. Now I've benefited a lot from lectures and many other academic reports.
Learning is a long process; I'll keep exploring in the treasure house of knowledge to enrich myself. This summer I got out of the ivory tower and entered the real world. A publishing house offered me a part-time job in compilation and revision.
At the beginning I was belittled by my colleagues. But they were really surprised when I translated seven English articles over 5,000 words on only one day. Gradually, they began to look at me with respectful eyes. In their opinion I turned out to be a useful and trustworthy colleague.
I also realize that only those who bring happiness for others can be truly happy. So I often take part in activities concerning public welfare. I once went to a barren mountain village with my classmates. We taught the kids there who could not afford school. While showing them how broad and how civilized the outer world is, I was deeply touched by their eagerness to learn, their honesty and their purity. I couldn't control my tears on the day when we left. The precious experience with the poor kids made me aware of the responsibility on the shoulders of us, future teachers.
Besides study and social practice, there are entertainments as well. I do body building every day, hoping to keep healthy and energetic. We also write a play and put it on in our spare time.
Campus life is the most splendid time. But different people have different choices. The majority of students cherish their beautiful season and cherish the hope that one day they'll become outstanding. But there are indeed some students still under ignorance. They gather together for eating, drinking or playing cards. They're busy in searching for a girlfriend or a boyfriend. They forget completely about their mission as college students and the hope of their motherland.
Finally, I do hope everybody can try their best to become a worthy citizen of the country. I do hope everybody can become the backbone of our nation and make great contributions to society!

Spring Festival
Spring Festival is the Chinese New Year Day. I enjoy it very much. On the Chinese New Year Day, some of our relatives come to visit us. They often give me some lucky money. Then I would play with their children. We often play firecrakers together, which is quite interesting.
At night the whole family would sit together, talking and watching TV programmes. Sometimes we take pictures of the whole family members in the house. I often go to bed late during the holiday, but I don't feel fired at all. I think the Spring Festival is the most enjoyable day for every family in China.
春节
春节是中国的大年初一。我非常喜欢。对中国的元旦,我们的一些亲戚来看望我们。他们经常给我一些压岁钱。然后,我将与他们的孩子玩。我们经常玩鞭炮在一起,这是很有趣的。
到了晚上,全家人会坐在一起,聊天,看电视节目。有时候,我们把整个家庭成员在家里的照片。我经常睡觉在长假后期,但我不觉得解雇的。我认为春节是最愉快的一天,每一个中国家庭。

Distinguished judges, teachers, dear friends:
Hello, everyone! My name is cheng xiang yan , I am a junior student come from life science institution .Today, I am very glad to stand here and share with you my most sincere speech‘Flying youth, master our future!’
Life is a process of growing up. Saying goodbye to childhood, we step into another important time of life in the pace of young, facing new situations, dealing with different problems.....
However, who can really say what the youth is ? A period of time? A belief?An attitude to life? Or anything else? actually, everyone has his ownunderstanding of young, it is a period of time of beauty and wonders, only after you have experienced the sour , sweet ,bitter and salty, can you really become a person of significance.
Just like A famous poet said ‘ youth is a lovely song ,where nothing is impossible ,youth is a meaningful book, you’ll be never bored of it ;youth is a rapid river ,it keeps on flowing day and night ;youth is a cup of tea ,it shows you different kinds of tastes in your life. ’
As youth is so precious, of course, we must treasure it .Don’t let the limited time pass by, grasping the young will means a better time is waiting for you in the near future.
So,It’s necessary for us to prepare ourselves well for the future to come. having a view on those great men in the history of hunman being, they all made full use of their youth time to do things that are useful to society, to the whole mankind, and as a consequence ,they are remembered by later generations, admired by everyone. so do something in the time of young, although you may not get achievements as these greatmen did ,though not for the whole world, just for youeself, for those around!
So, what should we do when we are young? Here,I’ll point out some tips to help equip ourselves.
First of all,think of what you’d like to be some day. A teacher ? A doctor ? A writer? Don’t afraid of dreaming of big and great .Since you are young , you can dream of doing anything and becoming anyone in the future.
What’s more , never ignore the power of knowledge. Read more books and travel around. For one thing, it can increase your knowledge, for another, it’ll broaden your horizon.
Last but not the least , stick to your dream. It easier said than done. After all, future is not all roses. young is just like blooming flowers, they are so beautiful when blooming, which make people feel happy, but with time passing by, after they withers ,most people think they are ugly. and so it is the same with young, we are enthusiastic when we are young, then we may lose our passion when getting older and older. So we should have enough courage and determination to overcome all the difficulties in struggling on the road.
I firmly believe one sentence that‘If you think you can, of course you can!’Just believe we can make it! Keep on walking towards our dream. Flying youth , master our future. From today, from now on , are you Ready ?
That’s all. Thank you so much for your attention !

WAR 战争
Though the people in the world are all opposed to war, they can by no means avoid it. This is indeed a regrettable thing.
War is very terrible. Everybody hears it with fear. In a war thousands and thousands of lives will be lost and a large amount of money (will be) wasted. It brings us untold miseries and damage.
To sum up, so long as war is unavoidable, human beings cannot enjoy lasting peace. How tragical their fate is!
虽然世界的人民都反对战争,但是他们却无法能够避免它。这确实是件非常令人遗憾的事情。
战争是非常可怕的。每个人听到它都害怕。在一次战争中,成千成万的人丧失了生命,大量金钱浪费了。它带给我们无穷尽的痛苦和损失。
总而言之,只要战争不可避免,人类不可能享受持久的和平。他们的命运是多么悲惨呀!

大学生实习周记范文大全(通用10篇)
大学生实习周记是指大学生在实习期间,每周对自己的工作经历、心得体会、成长变化等进行记录。以下是小编收集的关于大学生实习周记范文大全的相关内容,供大家参考!
在过去的三个月实习里面,在领导和同事的指导下,向行业学习知识,向同事请教经验,传授工作技巧,正是在这个过程中,认识到自己的不足之处,并不断的努力挖掘自己的长处。
在实习的开始头两个星期里,我主要是熟悉产品,包括:学习各种产品的使用和简单障碍处理、向客户详细介绍产品的性能和演示产品。纸上得来终觉浅,要知此事要躬行。课本上早已学过的东西,因为没有接触过实物,使得在刚使用机器时有“心有余而力不足”的感觉。
一款收款机,看起来很简单就是那么几个键,可要真正能熟练操作,我甚至用了比预期多一整天的时间才能真正地操作,但还不能和超市里的营业员们比。因为这是我接触的第一项产品,成绩如此不济,也激起了的兴趣和好学的愿望。
因此在以后的操作学习中,我倍加用功,专心致志,却也收到了事半功倍的效果。自己操作产品、熟悉产品,还不算难的,真正要下功夫学的是怎样向客户全面、生动,而又要简明、扼要、有所侧重要地介绍出自己的产品。这里面的关键是要会说,不仅要说对,还要说得能引起客户的兴趣,从而能成功地作成一庄生意。这也是对我一个巨大挑战,因为我本就不善言语,就更没有什么说话技巧和口才了,这也就是我就克服的困难。先是自己对着机器练,再是对着同事练,然后再找经理帮忙,要他装成顾客,我找他练,嘴皮子磨破了的时候,我也终于看到了经理脸上露出来的笑容。
接下来的一个星期里是实习业务阶段,就是通俗上说的“跑业务”。“跑业务”关键是要“跑”,要求我们能吃苦,能坚持,有韧力。因为业务技巧有过培训,产品自己也能了然于胸,但怎样正确地向客户表达出来,还需要师傅们实际教导。第一次接触生人,开始正式交谈,未免有些局促、放不开,话语的表达也不是很通顺、清楚、扼要,在跟着老师实际学习和模仿了几次以后,我基本上克服了第一次的毛病,老师也说好好了,并赞扬我进步很快。
再结束了师傅“带”的阶段之后,就是自己亲自独立上场,自己表演了。这也就是最后的7个礼拜的我的工作。所说已有了临场的经验,但毕竟是自己一个人出场,心中仍是存有余悸。因为我的工作主要就是向客户介绍、推广我们的餐饮软件,而人家显然是有备而来,对付的又是我这样的初出茅庐的新人,三下五去二就把我给摆平了。没用三句话,我就这样轻易地败下阵来,没有探出一句对我以后有用的信息,一次接触以后,我竟不知老板是谁,有没有分店,有多少员工,甚至没有留下经理的联系方法,更可悲的事是,我竟忘了请教他的姓名。
回到公司,经理问我出差情况,我无地自容,但也发誓一切要把这家搞定。这一次的失败,在我写给经理的报告中我作的深刻的反省,并向经理讨教了一些实用技巧。有了第一次的不幸和失败之后,我深知自己还很嫩,要学习和练习的东西还真得很多。因此,我在以后的实习工作中也充分认识到这一点,随时提醒自己要学习,所以在前面整整一个礼拜的无业绩之后,我终于迎来了我的第一个春天——我的第一桶金。这第一桶金就是从我第一次独自上路时跌倒的地方捡到的。
通过实习我明白到:工作往往不是一个人的事情,是一个团队在完成一个项目,在工作的过程中,如何去保持和团队中其他同事的交流和沟通也是相当重要的。一位资深人力资源专家曾对团队精神的能力要求有这样的观点:要有与别人沟通、交流的能力以及与人合作的能力。合理的分工可以使大家在工作中各尽所长,团结合作,配合默契,共赴成功。个人要想成功及获得好的业绩,我牢记一个规则:我永远不能将个人利益凌驾于团队利益之上,在团队工作中,会出现在自己的协助下同时也从中受益的情况,反过来看,自己本身受益其中,这是保证自己成功的最重要的因素之一。
其实营销最注重的是心态和胆量,真正拥有了这两点,成功离你已经不远了。

2023思政大讲堂第四讲直播心得大全(10篇)
思政大讲堂帮助学生树立正确的世界观、人生观和价值观。下面给大家分享一些关于2023思政大讲堂第四讲直播心得大全(10篇),希望能够对大家的需要带来力所能及的有效帮助。
现如今,我们的生活越来越离不开“科技”了,科技在当今的社会上无处不在,而科技对于我们一点也不陌生,因为我们每天都在享受科技:汽车,电脑,手机,冰箱……如果要说科技,恐怕三天三夜也说不完。但是,虽说科技有许许多多,但是,现如今完美的创作十分稀少……
我相信,现在的人们大多数都喜欢花,因为花的香味弥漫在屋中是多么美好的事情,但是,却因为家里居住在城市,家里没有足够的土壤而不能养一大片花,可能会因为这一方面感到伤心,难过……
我曾经有过一个想法,就是在墙上种花。在墙上种花看着不能实现,其实,想要在墙上种花不是很难。在墙上种花先要把一块木板划成五厘米的木条,用钉子把这些木条割一分米的距离一根一根地连着钉在墙上,并把两头用橡胶密封好,然后在这里面放入那一些花花草草,倒入养料,将这花草的根遮住就行了。最后,我们还可以用软的那一种水管割一分米弄一个小洞,并把这根水管弯弯曲曲地围绕这密密的.小槽的上面,并固定好。在那一面墙的最下面我们还可放一个塑胶的盒子,并在这里面装满水,把水管的上面一头放入盒子中,最后在盒子的表面倒入化学剂,这样,如果花草缺水,水就会因为表面的那一层化学物逆流而上,如果水足够了,它就会顺着水管流下来。
我的这一个创意不仅节约地面,而且能在家中种一片花的想法,我想:如果这个创意被采用,将来的世界就会成为花的世界。这个世界是那样的多姿多彩,那样的美好,人们是那样的快乐。

2024年度实习工作总结大全10篇
实习总结可以帮助大学生更好地理解理论知识,下面给大家分享一些关于2024年度实习工作总结大全10篇,希望能够对大家的需要带来力所能及的有效帮助。
转眼间三年的大学生活结束了,然而大多数人对本专业的认识还是不够,学校为了使我们更多了解机电产品、设备,提高对机电工程制造技术、自动化产品的认识,加深机电在工业各领域应用的感性认识,开阔视野,了解相关设备及技术资料,熟悉典型零件的加工工艺,我们先后去过__有限公司和__股份有限公司。了解这些工厂的生产情况,与本专业有关的各种知识,各厂工人的工作情况等等。亲身感受了所学知识与实际的应用,自动化技术在工业上的应用了,精密机械制造在机器制造的应用了,等等理论与实际的相结合。
我通过完成毕业实习过程,结合自己学习的知识,深入工厂企业实地参观与实习,达到自己的实习目的在这个基础上把所学的专业理论知识与实践紧密结合。
一、电工方面维护人员要求
1、认真观察。
通过眼睛的观察可以发现的异常现象有:破裂、断线;变形(膨胀、收缩、弯曲);松动;漏油、漏水、漏气;污_;腐蚀;磨损;变色(烧焦、硅胶变色、油变黑);冒烟(产生火花);有杂质异物;不正常的动作等等。
2、耳听鼻闻。
设备由于交流电的作用而产生振动并发出特有的声音,并呈现出一定的规律性。如果仔细倾听这些声音,并熟练掌握声音变化的特点,就可以通过它的高低节奏,音色的变化,音量的强弱,是否伴有杂音等,来判断设备是否运行正常。电气设备的绝缘材料因过热而产生的特有的焦糊气味,大多数的人都能嗅到,并能准确地辨别。值班人员在进入配电室检查电气设备时,如果闻到了设备过热或绝缘材料烧焦而产生的气味时,就应着手进行检查,看看有没有冒烟变色的地方,听一听有没有放电闪络的声音,直到找出原因为止。闻气味也是对电气设备某些异常和缺陷比较灵敏的一种判别方法。
3、用手触摸。
运行人员可用手触摸被检查的设备,来判断设备的缺陷和异常。应该强调的是,用手触试带电的高压设备是绝对禁止的。通过手摸,可以感觉出设备温度的变化和振动,如变压器的温度变化,局部发热;继电器的发热、振动等,都可以用触摸法检查出来。
4、了解运行状况。
设备检修人员向运行人员了解设备的运行状况,发生故障时的天气变化,负荷的大小,以往发生类似故障的记录及解决的办法等。通过这些“问”,可以较快地掌握设备运行的最基本的情况,便于检修人员快速完整地处理事故,避免事故查找工作进入误区而延长停电时间,扩大事故范围。
二、变电所
变电所引入两路高压电源,通过三路继电器控制,使高压电可以通过不同的备用设备输入,以便发生故障时进行维修。输入电压通过变压后,电压由110kv降为27.5kv。变压器是变电所的核心设备,内有绝缘油、干燥剂、散热器等。降压后的电压分为A、B两路,A相经过电压重分配变为数路电压,供给不同的用户。每路电压由上行线和下行线输出,可输出给用电火车。变电所控制室内装有控制设备,控制着所内一切仪器设备,还有先进的报警功能。
三、工厂供电与学校用电
在__有限公司还参观了工厂的一个电力系统图,反映该变电所的供电与用电布局。相比而言,工厂用电系统复杂,电压高,设备多。玻璃厂内有一个低压电所,起降压作用。另外有几个重要的设备:①中央信号盘,预告信号,显示故障;②控制盘,自投入;③空气开关;④直流系统,可蓄电;⑤油开关,利用瓦斯放电电解油,气体推动筏门导致开关;⑥无功功率补偿器,由于电动机为感性负载,需保证功率因数。

近日,一篇公号文章《请暂时遗忘袁隆平,我们应该认识一下这些给我们米饭吃的人们》,让中国工程院院士袁隆平在朋友圈获得了一波“新流量”。
首先,“请暂时遗忘袁隆平”,这个论题根本立不住脚。凭何让人们忘记袁隆平,又如何可以让人们忘记袁隆平?“吃水不忘打井人”,今天我们吃着袁隆平培育出的大米,你又让我们忘记袁隆平,除了忘恩负义,世上有这样的人吗?
其实,公号文章只是想说明:袁隆平“杂交水稻之父”名不符实;“给我们米饭吃”的人,除了袁隆平还大有人在;袁隆平的成就被“过度放大”,应该被“暂时遗忘”,把“舞台”留给其他科学家。真是岂有此理!我们不否认,“给我们米饭吃”的人不止是袁隆平一人,但仅仅是因此,我们就该忘记袁隆平吗?再说,现在是创新创造的时代,“舞台”就摆在每个人面前,用一句广告语来说:“心有多大,舞台就有多广。”“舞台”岂是给让出来的?君不见,占着茅坑不拉屎、在学术荣誉上殚心竭虑地造假者比比皆是,却不思如何作为,难道是社会没有给他们“舞台”吗?
再说,袁隆平是谁?相信多数的中国人都知道,他就是闻名中外的“杂交水稻之父”。但这个“荣誉”绝不是吹出来、夸出来的,而是他数十年孜孜不倦、潜心研究,用勤奋努力的汗水换来的。袁隆平是我国第一个发现水稻杂交优势现象的科学家,他1971年找到雄性不育系,1974年找到三系配套模式,此后成立“全国杂交水稻研究协作组”,1976年我国就实现了三系配套大规模制种,不到6年时间完成这些工作,速度之惊人,难道这些是能够让出来的吗?袁隆平的敏锐洞察力、超强组织力和坚定执行力,业界无不佩服,这也不是可以让出来的。
我们不妨看看央视《感动中国》节目给袁隆平的一段颁奖词:……民以食为天,人类从未停止过对饥饿的抗争,从未停歇过对粮食的渴望。面对严峻现实,世界陷入了粮食恐慌,人们连连发问:谁来养活中国,谁来养活世界?20世纪70年代,中国通过对杂交水稻的成功研究,最终将水稻亩产从300公斤提高到了800公斤,并推广2。3亿多亩,增产200多亿公斤。这些事迹都归功于今天的获奖者——袁隆平。
事实胜于雄辩,袁隆平今天依然奋斗不止,显然,公众号文章是罔顾事实,说袁隆平“杂交水稻之父”名不符实、成就被“过度放大”了,大有吃不到葡萄就说葡萄酸的意味。袁隆平,毕生梦想就是消除饥饿,他是一位真正的耕耘者。事实上,不论过去、还是今天,像袁隆平,还有屠呦呦一样成就卓著的科学家很多,他们淡泊名利,默默无闻,致力于科学研究。我们只见有学术造假者,从没见过哪位科学家的成就是被人让出来的。
可以说,袁隆平不可遗忘,也不可能被遗忘,他的科学贡献不但是对中华民族的,也是对世界的。他追求科学的精神,正是我们这个时代所需要。做人当有良心,那些鼓吹遗忘袁隆平者,那些妒忌袁隆平科学成就者,还是好好学习一下袁隆平的创造精神吧,别辜负了这个时代,要用自己的汗水去努力创新创造,机遇历来就对每个人都是平等的,舞台就摆在每个人的面前。

2023科技照亮梦想心得范文大全10篇
科技照亮梦想心得大家想知道该怎么写吗?科技照亮梦想心得新鲜出炉,下面给大家分享一些关于2023科技照亮梦想心得范文大全10篇,希望能够对大家的需要带来力所能及的有效帮助。
今天晴空万里,朵朵白云像甜丝丝的棉花糖,在天空飘荡着,诱得人好想上去咬一口。我怀着激动的心情来到淮阴工学院,参加一个神秘的实验活动。
我们跟着老师来到教室,我们准备的材料有:一个装了三分之一油的瓶子,一盒纯牛奶。我心想:就这些东西,它能做什么实验呀?这时老师对我们说:“这次实验的主题是——炫酷熔岩灯。”这让我更百思不得其解,这“炫酷熔岩灯”中的“熔岩”是火山里真的熔岩吗?还有这会是怎么个炫酷法呢?一系列问题在我脑海中环绕。
实验开始了,老师先让我们带着油瓶去卫生间加水,我发现尽管水是后加的,但它还是慢慢地沉到油下面。水加好了,瓶子里的水和油不但没混合,而且还分离得十分分明。这是为什么呢?我们带着疑问回到了教室。老师跟我们说:“水的密度大,油的密度小,所以水会沉到下面,油会浮上来。”紧接着,老师给我们发了色素。这有什么用呢?我心想。老师示意我们把色素滴进去,我用棉签蘸几下,滴入瓶中,那红色的色素像一块块红玛瑙掉了进去。“红玛瑙”快速地窜过油,在油和水交界处停留了一会儿,最后掉进了水里,“红玛瑙”慢慢地融化在水里,先一丝一丝,接着一条一条,最后完全融化在水中。然后,老师神神秘秘地拿出了一片一元硬币大小的白色药片,把它掰成两瓣,放进去,水就咕嘟咕嘟地沸腾起来,像我在电视上看到的火山爆发时,那沸腾的熔岩似的,光彩鲜明、璀璨夺目。我们都在想:老师放进去的药片,到底是什么灵丹妙药啊?同学们都七嘴八舌地议论起来。有些聪明的同学已经猜出来了,那就是泡腾片。老师给我们每人发了一片泡腾片,我们小心翼翼地把泡腾片放入瓶子里,它先是在瓶底沸腾了几下,接着速度越来越快,面积越来越大,它上下翻腾着,蔚为壮观!
实验结束后,老师告诉我们:“这是个化学原理,泡腾片通常是有机酸和小苏打的混合物,当你把泡腾片放入水中后,有机酸和小苏打在水的作用下电离,并发生复分解反应,产生大量二氧化碳,也就是气泡,在水里生成的气泡中间会有一些水,水中我们又加了色素,就产生了岩浆喷射的奇观。”
通过这次实验,我懂得了一个道理:只要细心观察,生活处处都有科学!

小学英语培训收获感悟心得(素材8篇)
写心得的过程就是对学习的新知识点进一步加深学习,帮助自己对学习到的新知识有一个更加深刻的理解和记忆。如何撰写优秀的小学英语培训收获感悟心得?这里分享一些小学英语培训收获感悟心得写作案例,供大家参考。
我很荣幸地参加了由县教研室组织的小学英语骨干教师的培训。通过三天的学习,犹如为我打开了一扇窗,拨云见日,使我在一次次的感悟中豁然开朗。学习内容如下:
首先,教研员李老师做了《如何搞好网络大集体备课》的发言,强调了八个问题,不仅为常识大集体备课指明了方向,而且激发了与会老师们参加集体备课的高度热情。这八个问题是:
一、网络大集体备课的含义;
二、与以往集体备课的联系与区别;
三、网络大集体备课的意义及优点;
四、集体备课的内容与范围;
五、大集体备课的形式与要求;
六、大集体备课基本程序;
七、搞好大集体备课要应该树立的三种意识;
八、集体备课的几种误区。
然后,教研员李老师结合所制作的课件,向大家介绍了以下内容:
一、如何建立并加入协作组;
二、如何把集体备课的成果上传到网络教研平台;
三、如何修改共案形成个案;
四、如何在共案中发布资源并发表评论。图文并茂的讲解方式,使老师们直观形象地掌握了大集体备课的网络操作步骤,为今后大集体备课的实际操作打下了良好的基础。
通过三天的学习使我学到了当前先进的教育教学初中化学资源网理论,为以后的工作积蓄了力量、理清了思路,更加明确了目标。如果用一个词语来概括参加本次活动的体会,那就是受益匪浅。下面是我通过培训获得的点滴体会:
我认为集体备课正是为大家搭建了一个学习、交流、和资源共享的平台,是提高课堂教学效率的有效措施,它可以发挥集体的智慧,帮助教师加深对教材的理解,拓展教学思路,使教师们达成教学的共识,有了教学的共同目标。网络教研是一种以网络为手段开展教研工作的新方式,网络能给予我们无穷的信息和资源,网络能使我们的教育资源得到共享。构建高效课堂的根本保障是课堂教学,很大程度上取决于备课是否充分,是否有效。网络大集体备课是把备课的方式由机械重复备课向积累优化式备课转变,个人封闭式备课向合作开放式备课转变,文本式向电子式备课转变,为教师减负增效。
教学过程中要坚持与日俱进,弘扬创新精神。这几年,教育理论层出不穷,教育信息日新月异,我们只有不断地学习教育理论,更新教育观念,提高教改水平,才能适应教育改革的需要。通过学习,给自己也补充了新鲜的血液,我一定要把这些新的理念,新的教学方法在实际的教学工作中实施贯彻好,为国家培养好适应社会发展的好人才,才能与日俱进,不断创新。
相信通过自己不懈的努力,用自己的真诚和爱心去对待每一个学生,在教育事业中做出成绩。
