This morning, mr. Huang was taking 4 eggs and a bowl to walk into a classroom, laugh ah breathe out the ground to say: We come to “ today do a scientific little test. Look can grasp broken an egg, who is willing to try? ”“ is breathed out, is this cole dishful? ” I can't help happy phonate comes. “ I! ”“ chooses me! I come to ”“ ! ” classmates in succession raise one's hand, the ground was brushed to grow a grove in the classroom. Mr. Huang nods approvingly, call Xiaoming. Xiaoming is excited happy to dance, was on dais feeling pleasedly. He takes an egg to put the centre of the palm, sucked deeply at a heat, exert all one's strength grasped rise. One minute went, dichotomy bell went, the egg did not break, dan Xiaoming's face already hold back is gotten aglow. “ is cheered! ”“ exerts oneself to do sth. ! ”“ holds to! ” classmates cried to rise. Xiaoming exert the effort that suck the breast, it is how not small egg. A little while, he puts down an egg cautiously, easy of long long ground at a heat.
今天上午，黄老师拿着四个鸡蛋和一只碗走进了教室，笑呵呵地说：“今天我们来做一个科学小实验。看看能不能握碎一个鸡蛋，谁愿意来试一试？”“哈哈，这不是小菜一碟？”我不禁乐出声来。“我！”“选我！”“我来！”同学们纷纷举手，教室里刷地长出了一片小树林。黄老师满意地点了点头，叫小明上去。小明激动得手舞足蹈，喜滋滋地走上了讲台。他拿起鸡蛋放入掌心，深深地吸了一口气，使劲握了起来。一分钟过去了，两分钟过去了，鸡蛋没有碎，但小明的脸已经憋得通红。“加油！”“用力啊！”“坚持！”同学们喊了起来。小明使出了吃奶的力气，就是奈何不了小小的鸡蛋。一会儿，他小心翼翼地放下鸡蛋，长长地舒了一口气。
Classmates are eristic in succession: The effort that “ is him certainly is too little. ”“ egg carapace is much flimsier, how can you grasp do not break? Mr. ”“ , I will try! ” small Wei, small house, small red in spirits is on a stage, after holding an egg, return a seat crestfallenly.
同学们议论纷纷：“一定是他的力气太小了。”“鸡蛋壳多脆弱呀，怎么会握不碎呢？”“老师，我来试一试！”小伟、小宇、小红兴致勃勃走上台去，握过鸡蛋之后，垂头丧气地回到座位。
Classmates are consistent press is small brightness go trying. Small brightness it is our class stature is highest, the figure is big and tall, resemble a turret. The ground is on his valiantly full of mettle dais, a pair of annals is in the appearance that must. He reachs an old hand, hold the egg in the centre of the palm, begin put forth one's strength. I think: The egg should be met be grasped to break! Classmates look at him nervously. See the blue veins on his forehead is cruel only case, ooze went out fine fine sweat bead, show joint bleached, but the egg wore a solid armor it seems that, safe and sound.
同学们一致推举小辉去试试。小辉是我们班个子最高的，身材魁梧，就像一座小塔。他雄赳赳气昂昂地走上讲台，一副志在必得的样子。他伸出一只大手，把鸡蛋握在掌心，开始用劲。我想：鸡蛋应该会被握碎吧！同学们都紧张地看着他。只见他额头上青筋暴起，沁出了细细的汗珠，指关节都变白了，可鸡蛋似乎穿了一层坚固的铠甲，安然无恙。
When the teacher says who goes holding two eggs single-handed, classmates resemble discharge angry rubber ball, how to also rouse disinclination, of neither one raise one's hand. Grand grand is mischievous, raise one's hand is put down again, was discovered by the teacher, be called. He takes two eggs very helplessly, toughen one's scalp-brace oneself is grasped. My day! The egg broke actually! He also does not have expect probably, be frightened the face is in vain. the Hercules that grand grand just is my class?
当老师说谁去一手握两个鸡蛋时，同学们就像泄了气的皮球，怎么也鼓不起劲来，没有一个举手的。浩浩顽皮，举手又放下，被老师发现了，被叫上去。他十分无奈地拿起两个鸡蛋，硬着头皮一握。我的天！鸡蛋竟然碎了！他大概也没有料到，吓得脸都白了。难道浩浩才是我班的大力士？
Mr. Huang sees the look of our feel puzzled, explain: “ the mystical place that this is shell structure. Egg carapace can go to the outside force that get equably dispersedly everywhere, the force that each place gets becomes very special small. So, your strength is again great, also grasp do not break an egg. But grasp two eggs to differ, dot getting power is in the place with two conterminous eggs, want in a way to be able to be grasped forcibly only so broken. ”“ architect people the principle that uses shell structure, the design went out a lot of already light save the building of makings again, be like railway station of the people congress hall of our country, Beijing, sydney opern of Australia. ”
黄老师见我们疑惑不解的样子，就解释道：“这就是薄壳结构的神奇之处。鸡蛋壳能把受到的外力均匀地分散到各处，每一处受到的力就变得非常非常小。所以，你力气再大，也握不破一个鸡蛋。但握两个鸡蛋就不同了，受力点在两个鸡蛋相接的地方，所以只要稍稍用力就能握破。”“建筑师们利用薄壳结构的原理，设计出了许多既轻便又省料的建筑物，如我国的人民大会堂、北京火车站，澳大利亚的悉尼歌剧院等。”
This scientific little test, make us big open horizon. The common egg in the life, actually contain is worn the secret that does not know for us. I want work energetically study, think frequently, become a scientist later.
这个科学小实验，令我们大开眼界。生活中司空见惯的鸡蛋，竟然蕴藏着不为我们了解的秘密。我要发奋学习，勤动脑筋，以后当一个科学家。(文/孙国翔)
