This years Spring Festival, I read" the old man and the sea", is a famous American writer Hemingway wrote. I admire the old fisherman in the novel very much, he lets me understand that a person must have unremittingly spirit, could succeed. This novel is a description of a nearly sixty years old, alone in fishing, caught a big fish, but can not draw. The old fisherman and fish deal after several days, they find it is a big Malin fish over several times their own boats, while knowing that it is difficult to win, does not give up yet.
自从我认识了黄金比,得知黄金比在生活中很常见,于是我又进行了课外拓展,了解了斐波那契数列。
斐波那契数列,顾名思义是由斐波那契发现的。指的是这样一个数列:0、1、1、2、3、5、8、13、21、34、……此数列的特点是:这个数列从第3项开始,每一项都等于前两项之和。用关系式来表达就是:n(数列的第n个数,n≥3=n-1+n-2。此外,还有一个特点,那就是从第二项开始。每个奇数项的平方比前后两个项的积少1;每个偶数项的平方比前后两个项相乘的积多1。斐波那契数列最大的特点就是从第三个项开始,前面两个项的和与后面一个项的比值无限接近于黄金比(0.6180339。
这个数列在生活中很常见,例如葵花、鹦鹉螺等等都有斐波那契数列的影子。最神奇的.是,这个数列与我国古代数学家杨辉发现的杨辉三角有极大的相连关系。在现代物理、准晶体结构、化学等领域,斐波那契数列都起到很重要的作用。
诸如大家平时耳熟能详的断臂维纳斯,人民大会堂。古埃及的一些建筑,到处都有斐波那契数列的身影。数列不仅增加建筑体的美观形象,还增加了建筑体的质量。斐波那契数列还有一个别称,那就是兔子数列。兔子的繁殖与斐波那契数列十分相似。在一些专门饲养兔子的农厂掌握斐波那契数列,可以更好的掌握兔子数量的增减,从而达到节省饲料的目的。
斐波那契数列在我们平时的生活中还有什么用处呢?答案是肯定有的,于是我就想到了在表演才艺中是不是也可以用到?例如表演魔术:在一张纸上并排画11个小方格。让人背对着自己(确保自己看不到他在纸上写什么,在前两个方格中随便填两个1到10之间的数。从第三个方格开始,在每个方格里填入前两个方格里的数之和。让对方一直算出第10个方格里的数。现在,叫对方报出第10个方格里的数,自己只需要在计算器上按几个键,便能说出第11个方格里的数应该是多少。对方会非常惊奇地发现,把第11个方格里的数计算出来,所得的结果与你的预测一模一样!这就奇怪了,在不知道头两个数是多少的情况下,只知道第10个数的大小,不知道第9个数的大小,怎么能猜对第11个数的值呢?其实只需要将第十个数除以0.618......就可以得到正确的结果,假如第十个数是249,则可以将249÷0.618......≈403,最后就会发现,结果是一模一样。
斐波那契数列仅仅是数学海洋一个缩影,知识是来源于生活,从而又服务于生活。合理的利用,才能将知识的作用与力量发挥到极致!
Tonight I watched the movie for the third time. I really enjoy this film so much.
So what's your choice between being a common person or a hero with people's reects? Most people will choose the latter. But what will be your choice if the cost is laying your lover among the risks? What will it be if the cost is you can never tell the girl, who you love so much, that you love her? The ider man had this contradiction. But finally he still chose the latter, not in order to be a hero, but to make this word peaceful.
I was so moved by the words the Aunt Mary said:
You will never guess what he wants to be, the ider man. He knows the hero when he sees one, too a few characters out there, flying all around out there, saving old girls like me. Lord knows kids like Henry need hero courageous, sacrificing for people, setting examples for all of us. Everybody loves a hero. People enthrone them, cheer them, scream their names and years later they will tell how they stood in the rain for hours just to get a glimpse the one who taught them to hold on to stand longer. I believe there is a hero in all of us. They keep us be honest, give us strength, make us noble, and finally allow us to die with proud. Ever though sometimes we have to initiatively give up the thing we want most, even our dreams. Spider man did that for Henry, so he wants to know where he is gone. He needs him.
The ider man got much from these words, so did I. And what about you? what's the hero lying in you?
This is a story about a special and ueserved woman who has been exposed to a hostile environment but continuously and fearlessly struggling for her ideal life. The story can be interpreted as a symbol of the independent spirit.
It seems to me that many readers’ English reading experience starts with Jane Eyer. I am of no exception. As we refer to the movie “Jane Eyer”, it is not surprising to find some differences because of its being filmized and retold in a new way, but the spirit of the novel remains----to be an independent person, both physically and mentally.
Jane Eyer was a born resister, whose parents went off when she was very young, and her aunt,the only relative she had,treated her as badly as a ragtag. Since Jane’s education in Lomon person, just the same as any other girl around. The suffers from being humiliated and devastated teach Jane to be persevering and prize dignity over anything else.As a reward of revolting the ruthless oppression, Jane got a chance to be a tutor in Thornfield Garden. There she made the acquaintance of lovely Adele and that garden’s owner, Rochester, a man with warm heart despite a cold face outside. Jane expected to change the life from then on, but fate had decided otherwise: After Jane and Rochester fell in love with each other and got down to get marry, she unfortunately came to know in fact Rochester had got a legal wife, who seemed to be the shadow following
Rochester and led to his moodiness all the time ----Rochester was also a despairing person in need of salvation. Jane did want to give him a hand, however, she made up her mind to leave, because she didn’t want to betray her own principles, because she was Jane Eyer. The film has finally got a symbolist end: Jane inherited a large number of legacies and finally returned. After finding Rochester’s misfortune brought by his original mad wife, Jane chose to stay with him forever.
I don’t know what others feel, but frankly speaking, I would rather regard the section that Jane began her teaching job in Thornfield as the film’s end----especially when I heard Jane’s words “Never in my life have I been awaken so happily.” For one thing, this ideal and brand-new beginning of life was what Jane had been imagining for long as a suffering person; for another, this should be what the audiences with my views hoped her to get. But the professional judgment of producing films reminded me to wait for a totally different result: There must be something wrong coming with the excellence----perhaps not only should another section be added to eich the story, but also we may see from the next transition of Jane’s life that “Life is like a box of chocolates, you never know what you would get.” (By Forrest Gump’s mother, in the film “Forrest Gump”
What’s more, this film didn’t end when Jane left Thornfield. For Jane Eyer herself, there should always be somewhere to realize her great ideal of being independent considering her fortitude, but for Rochester, how he can get salvation?
The film gives the answer tentatively: Jane eventually got back to Rochester. In fact, when Jane
met Rochester for the first time, she scared his horse and made his heel strained, to a certain extent, which meant Rochester would get retrieval because of Jane. We can consider Rochester’s experiences as that of religion meaning. The fire by his frantic wife was the punishment for the cynicism early in his life. After it, Rochester got the mercy of the God and the love of the woman whom he loved. Here we can say: human nature and divinity get united perfectly in order to let such a story accord with the requirements of both two sides. The value of this film may be due to its efforts to explore a new way for the development of humanism under the faith of religion.
Life is ceaselessly changing, but our living principles remain. Firmly persisting for the rights of being independent gives us enough confidence and courage, which is like the beacon over the capriccioso sea of life. In the world of the film, we have found the stories of ourselves, which makes us so concerned about the fate of the dramatis personae.
In this era of rapid social and technological change leading to increasing life complexity and psychological displacement, both physical and mental effects on us call for a balance. We are likely to find ourselves bogged down in the Sargasso Sea of information overload and living unconsciousness. It’s our spirit that makes the life meaningful.
Heart is the engine of body, brain is the resource of thought, and great films are the mirrors of life. In
dubitably, “Jane Eyer” is one of them.
