各位老师，各位同学：
大家好!我叫。今天，我演讲的题目是--《诚信，永不凋零的心灵之花》。
20xx年X月，《扬子晚报》刊登过这样一条新闻：安徽滁州一位50多岁的老农民来到南京，等他打算回家时才发现，口袋里的钱买车票还差5元。他在南京举目无亲,在万般无奈之下，他向玄武区的一位民警借了5元钱。5元钱，也许，谁也不会放在心上，更何况是一个被城里人认为素质并不高的农民借去的呢?但是，第二天一大早，这位农民却将5元钱给这位民警送来了。
这是一个很简单的故事，没什么曲折离奇、扣人心弦的情节，但它透露出来的质朴，折射出来的诚信，却不能不震撼人们的心灵。
《狼来了》的故事我们实在听得太多太多了。然而，因丢诚信而失羊的痛苦教训，你吸取了吗?亲爱的朋友们，请吸取放羊娃的教训!不要再愚蠢地认为在丢失诚信后还可以再挽回。难道被狼叨走的羊儿还无法唤醒你的觉悟吗?难道你愿意过那种除了欺骗，还是欺骗的生活吗?如果你的回答是不的话，那么，请你把“诚信”时时放在你心中吧!
诚信，是春天的花儿，只有开过花，才会结出完美的硕果;
诚信，是建房的泥浆，缺少它的粘合，便不会有牢固的大厦;
诚信，是植物的肥料，没有它的注入，就不会有茁壮的绿物。
鲁迅先生说过：“诚信，为人之本也!诚信，比金钱更具有吸引力，诚信，比美貌更具有可靠性，诚信比荣誉更有时效性!”
是啊!诚信，是一种美德，是一种源源不断的财富;诚信，是一种取之不尽，用之不竭的智慧。
诚信，像永恒的星辉，独放光彩，
诚信，以水滴石穿的坚毅渗入人心，
诚信，用春风般的胸怀感召着众人!
诚信，是耀眼璀璨的阳光，他的光芒普照大地;
诚信，是广阔无垠的大地，他的胸怀承载山川;
诚信，是秀丽神奇的山川，他的壮丽净化人们的心灵;
诚信，是最美丽、最圣洁的心灵，他让人问心无愧、心胸坦荡。
诚信，如此珍贵，我们应该从我做起，从现在做起，让诚信的种子，在我们的心田中，生根、发芽、开花、结果。
同学们，让我们守住诚信的阵地，让诚信之花永远绚丽，永远绽放!
我的演讲完了，谢谢大家!

someone said “we are reading the first verse of the first chapter of a book, whose pages are infinite”. i don?t know who wrote these words, but i?ve always liked them as a reminder that the future can be anything we want it to be. we are all in the position of the farmers. if we plant a good seed ,we reap a good harvest. if we plant nothing at all, we harvest nothing at all.
we are young. “how to spend the youth?” it is a meaningful
question. to answer it, first i have to ask “what do you understand by the word youth?” youth is not a time of life, it?s a state of mind. it?s not a matter of rosy cheeks, red lips or supple knees. it?s the matter of the will. it?s the freshness of the deep spring of life.
youth means a temperamental predominance of courage over
timidity of the appetite , for adventure over the love of ease. this often exists in a man of 60 more than a boy of 20 . nobody grows old merely by a number of years . we grow old by deserting our ideals. years wrinkle the skin , but to give up enthusiasm wrinkles the soul . worry , fear , self –distrust bows the heart and turns the spirit back to dust .
whether 60 of 16 , there is in every human being ?s heart the lure of wonders, the unfailing childlike appetite of what?s next and the joy of the game of living . in the center of your heart and my heart there?s a wireless station : so long as it receives messages of beauty , hope ,cheer, courage and power from men and from the infinite, so long as you are young .
a poet said “to see a world in a grain of sand, and a heaven in a wild flower, hold infinity in the palm of your hand, and eternity in an
hour. several days ago, i had a chance to listen to a lecture. i learnt a lot there. i?d like to share it with all of you. let?s show our right palms. we can see
three lines that show how our love.career and life is. i have a short line of life. what about yours? i wondered whether we could see our future in this way. well, let?s make a fist. where is our future? where is our love, career, and life? tell me.yeah, it is in our hands. it is held in ourselves.

尊敬的老师，亲爱的同学们：
大家早上好!
今天我要演讲的题目是乐观的生活态度。
曾看过这样一段话：小鸟说：我从天空中飞过，但天空中没有留下我的痕迹。泰戈尔说，天空中没有留下我的痕迹，但我已飞过。同样的状况，却有两种不同的态度，相信后者的态度更能赢得大家的认可。
其实生活是一面镜子，你对他笑，他就会向你露出笑脸，你对它哭，那么你最终只会收获沮丧的心情。但也总是有很多人会有抱怨，他们会说上天是如此的不公平，努力奋斗多年的我到现在为止还是一个经理助手。寒窗苦读十二年书的我，最终还是没能考上理想的大学。然而，这些抱怨无法改变现实，只能加重自己的烦恼，何不以积极乐观的心态看待呢?

亲爱的老师、同学们：
高尔基说“书籍是人类进步的阶梯。”我觉得这句话说的特别精彩。因为书，是人类文化遗产的结晶;也是人类智慧的仓库，只有多看书，才能进步。
书，让我们了解了许多东西，那些都是课堂上学不到的。也让我们懂得了各种各样的做人的道理。《福尔摩斯探案选集》的故事告诉我们：做事要仔细观察，认真思考，遇事要沉着冷静;《木偶奇遇记》告诉我们：不要贪玩，要好好学习、天天向上，不要光顾玩，而忘了学习。也不要辜负了家长的我们的期望!
小时候，我听父母讲故事，一、二 年级，我们喜欢幼稚的连环画书，三年级时，我就开始看注音版的故事书。再大些，我就开始读少年版的各种名著。现在，我就看一些世界名著，像《海底两万里》《假如给我三天光明》等，这些都是国外的一些著名作家写的。我非常喜欢读。
书，能使我们大开眼界;书里蕴含着丰富的知识。书，是人生中必不可少的东西，我们要多看书，因为，书，能够把我们带上成功之路。也能把我们送上知识的彼岸。因为书是我们走上成功的阶梯，也是成功之路上的一盏灯，每时每刻照着我们。
我爱读书!

柏拉图告诉弟-子自己能够移山，弟-子们纷纷请教方法，柏拉图笑道，说：“很简单，山若不过来，我就过去。”弟-子们一片哗然。
这一个世界上根本就没有移山之术，唯一的一个移动山的方法就是：山不过来，我便过去。同样的道理，人不能改变环境，那么我们就要改变自己。
一个黑人小孩在他父亲的葡萄酒厂看守橡木桶。每天早上，他用抹布将一个个木桶擦干净，然后一排排地整齐地放好。令他生气的是，往往一夜之间，风就把他排列整齐的木桶吹得东倒西歪。
小男孩很委屈地哭了。父亲摸着小男孩的头说：“孩子，不要哭，我们可以想办法去征服风。”
于是小男孩擦干了眼泪坐在木桶边想啊想，想了半天终于想出了一个办法，他从井边挑来一桶又一桶的清水，然后把它们倒进那些空空的橡木桶里，然后他就忐忑不安地回家睡觉了。第二天，天刚蒙蒙亮，小男孩就匆匆地爬了起来，他跑到放桶的地方一看，那些橡木桶一个一个排列得整整齐齐，没有一个被风吹倒的，也没有一个被风吹歪的。小男孩开心地笑了，他对父亲说：“要想木桶不被风吹倒，就要加重木桶的重量。”男孩的父亲赞许地微笑了。
是的，我们不能改变风，改变不了这个这个世界上的许多东西，但是我们可以改变自己，给自己加重，这样我们就可以适应变化，不被打败!
在威斯敏斯特教堂地下室里，英国圣公会主教的墓碑上写着这样一段话：当我年轻自由的时候，我的想象力没有任何局限，我梦想改变这个世界。当我渐渐成熟明智的时候，我发现这个世界是不可改变的，于是我将眼光放得短浅了一些，那就只改变我的国家吧!但是我的国家似乎也是我无法改变的。当我到了迟暮之年，抱着最后一丝努力的希望，我决定只改变我的家庭、我最亲近的人——但是，唉!他们根本不接受改变。现在我在临终之际，我才突然意识到：如果起初我只改变自己，接着我就可以依次改变我的家人。然后，在他们的激发和鼓励下，我也许能改变我的国家。再接下来，谁又知道呢，也许我连整个世界都可以改变。
人生如水，人只能去适应环境。如果不能改变环境，就改变自己，只有这样，才能克服更多的困难，战胜更多的挫折，实现自我。如果不能看到自己的缺点和不足，只是一味地埋怨环境不利，从而把改变境遇的希望寄托在改变环境上，这实在是徒劳无益。
虽然我们不能改变世界，但我们可以改变自己，让我们用爱心和智慧来面对一切环境。

the nature of impeachment: a narrowly channeled exception to the separation-of-powers maxim. the federal convention of 1787 said that. it limited impeachment to high crimes and misdemeanors and discounted and opposed the term "maladministration." "it is to be used only for great misdemeanors," so it was said in the north carolina ratification convention. and in the virginia ratification convention: "we do not trust our liberty to a particular branch. we need one branch to check the other."
"no one need be afraid" -- the north carolina ratification convention -- "no one need be afraid that officers who commit oppression will pass with immunity." "prosecutions of impeachments will seldom fail to agitate the passions of the whole community," said hamilton in the federalist papers, number 65. "we divide into parties more or less friendly or inimical to the accused."³ i do not mean political parties in that sense.
the drawing of political lines goes to the motivation behind impeachment; but impeachment must proceed within the confines of the constitutional term "high crime[s] and misdemeanors." of the impeachment process, it was woodrow wilson who said that "nothing short of the grossest offenses against the plain law of the land will suffice to give them speed and effectiveness. indignation so great as to overgrow party interest may secure a conviction; but nothing else can."
common sense would be revolted if we engaged upon this process for petty reasons. congress has a lot to do: appropriations, tax reform, health insurance, campaign finance reform, housing, environmental protection, energy sufficiency, mass transportation. pettiness cannot be allowed to stand in the face of such overwhelming problems. so today we are not being petty. we are trying to be big, because the task we have before us is a big one.
this morning, in a discussion of the evidence, we were told that the evidence which purports to support the allegations of misuse of the cia by the president is thin. we're told that that evidence is insufficient. what that recital of the evidence this morning did not include is what the president did know on june the 23rd, 1972.
the president did know that it was republican money, that it was money from the committee for the re-election of the president, which was found in the possession of one of the burglars arrested on june the 17th. what the president did know on the 23rd of june was the prior activities of e. howard hunt, which included his participation in the break-in of daniel ellsberg's psychiatrist, which included howard hunt's participation in the dita beard itt affair, which included howard hunt's fabrication of cables designed to discredit the kennedy administration.
we were further cautioned today that perhaps these proceedings ought to be delayed because certainly there would be new evidence forthcoming from the president of the united states. there has not even been an obfuscated indication that this committee would receive any additional materials from the president. the committee subpoena is outstanding, and if the president wants to supply that material, the committee sits here. the fact is that on yesterday, the american people waited with great anxiety for eight hours, not knowing whether their president would obey an order of the supreme court of the united states.
at this point, i would like to juxtapose a few of the impeachment criteria with some of the actions the president has engaged in. impeachment criteria: james madison, from the virginia ratification convention. "if the president be connected in any suspicious manner with any person and there be grounds to believe that he will shelter him, he may be impeached."

i have a dream
i am happy to join with you today in what will go down in history as the greatest demonstration for freedom in the history of our nation.
five score years ago, a great american, in whose symbolic shadow we stand today, signed the emancipation proclamation. this momentous decree came as a great beacon light of hope to millions of negro slaves who had been seared in the flames of withering injustice. it came as a joyous daybreak to end the long night of their captivity.
but one hundred years later, the negro still is not free. one hundred years later, the life of the negro is still sadly crippled by the manacles of segregation and the chains of discrimination. one hundred years later, the negro lives on a lonely island of poverty in the midst of a vast ocean of material prosperity. one hundred years later, the negro is still languished in the corners of american society and finds himself an exile in his own land. and so we've come here today to dramatize a shameful condition.
in a sense we've come to our nation's capital to cash a check. when the architects of our republic wrote the magnificent words of the constitution and the declaration of independence, they were signing a promissory note to which every american was to fall heir. this note was a promise that all men, yes, black men as well as white men, would be guaranteed the "unalienable rights" of "life, liberty and the pursuit of happiness." it is obvious today that america has defaulted on this promissory note, insofar as her citizens of color are concerned. instead of honoring this sacred obligation, america has given the negro people a bad check, a check which has come back marked "insufficient funds."

同学们，老师们早上好。今天由我来为大家作自我介绍。大家对我介绍这个题目应该会觉得很老土吧，希望我一下多的内容不会让大家觉得无聊。
我叫，今年13岁。我没有什么兴趣，只不过每样东西都会一点，但不精通。例如唱歌吧，我很喜欢唱流行歌，上街时候的我都会哼上一两句。但不知道为什么，我每次场唱到高音时，总会走音。而且我最大的一个毛病是喜欢看电视，天天看，晚晚看。但我的妈妈是我的死对头，每晚都要我复习。记得一天晚上，我趁妈妈上洗手间时，大概只有4—5分钟。我一极快的速度跑到客厅，把电视机开了，还把音量调到最少。正当我看得入迷时，我忽然觉得耳朵有一丝凉风吹过。转头一看，妈妈用她那超级大电眼来盯着我看，然后跟我说："小朋友，你做完功课吗?"那不阴不阳的语气让我觉得心惊胆颤，说时迟，那时快，妈妈一手抓起我的衣领，把我拖到了房间，叫我读书。这还不算什么，最令我不爽的是，他居然知道我躲在被窝里看小说，然后冷冷的把我的小说给收了。人家常说寓娱乐工作，可是我家却是将一切娱乐活动取消。
但站在父母亲的立场来说，他们也许只是想我们读多点书，以后我找份好工作。照我说，应该让娱乐和学习取得平衡，让各自知道大家的好处，那不就行了吗?

大家好！
在人生的旅途中，梦想是的伙伴，如果说梦想是一棵常青树，那么，浇灌它的必定是出自心田的清泉；如果说梦想是一朵常开不败的鲜花，那么，照耀它的必定是从心中升起的太阳。太阳与清泉，交相呼应，而我们的生命，也会因为有了梦想而变得更加精彩。
梦想是用永恒的执着和顽强的韧劲筑起的一道铜墙铁壁，她固若金汤。
梦想是用不凋的希望和不灭的向往编制的七色彩虹，她绚丽辉煌。人们常说：“失败是成功之母。”但又有多少人能够面对挫折，仍然坚挺着呢？
梦想是用意志的血滴和拼搏的汗水酿成的琼浆，她历久弥香。在我心中有一个坚强的身影，她就是舞蹈家邰丽华，在她两岁那年，因高烧而失去了听力，难以想象她当时的寂寞与痛苦，在她婀娜的舞姿背后，她付出了比常人多好几倍的辛苦。台上一分钟，台下十年功。她说她爱舞蹈，虽然没有音乐，但是她用自己的心去伴奏。她是舞台上一株美丽的奇葩。她从不叫苦叫累，只是默默坚持着。她所做的一切，只为了心中那个舞蹈梦。她成功了。《千手观音》给了观众艺术的美感，她们优美的舞姿震慑了所有人的眼睛。邰丽华的生命因为有了梦想而精彩。
谢谢。

尊敬的老师们，亲爱的同学们：
大家好!
不忘初心，信念长存
在初一初二时老是有人问我：你的理想是什么或者你长大想要干什么，我总是睁着茫然的眼睛摇摇头，然后他们就语重心长地跟我说”你怎么能没有理想呢?这么大了，总有自己的思想吧，没有一个目标哪会有信念，没有信念哪来的动力呢”我每次都浑浑噩噩地点点头;直到现在才知道原来信念是多么重要，她能让我们前进的动力更大因为信念仿佛是心中的信仰，让我们的心有一个坚强的后盾，让我们更加坚定不移的向目标前进。
不忘初心，坚持不懈
再坚定自己的信念如果不坚持也只是幻想。梦想离我们是遥远的。初一的时候我成绩还不错，可是我这个人比较懒散，总是不能坚持，喜新厌旧，对我自己感兴趣的事会干劲很足，对我自己不感兴趣的事就两三下完事，还有一种就是凭新鲜感做事，有些事情刚开始我兴趣会特别大但是可能过个几个月我就会失去兴趣，中途放弃。比如学习钢琴，刚开始学的时候我天天练天天练而且弹琴的时候身心会特别舒畅，但是学了两三个月后我就开始逃避钢琴课，每次上课都愁眉苦脸，手机给老师的备注都是“烦人老师”。到了最后，我的钢琴就荒废了上面蒙了一层灰。现在想起来真是放弃了一门特长啊!所以说心中不仅要有理想有目标，还要朝着那个方向不断前进，坚持不懈才能达到梦想的彼岸。
不忘初心，脚踏实地
在追逐梦想的途中，难免会浮躁，浮躁会像苍蝇一样缠着你，但你千万不能被他干扰，妄想一步登天，而要将路一步一步走好否则会一个“健步”就掉下了悬崖。如果只是心中有想法而行动上慢半拍，那就只是好高骛远而不是有梦想。我有一个小学同学，她非常心中的目标非常高，但总是好想懒做。她总是跟我们说她以后要考品牌大学，但是事实上她总是不把学习当回事，整天游手好闲，上课老是跟别人打闹，成绩自然不好。我当时就在想：就她这样下去别说考大学了，考高中都有困难。果不其然，这个女孩毕业考试考得特别差。这难道不是好高骛远吗?你看，如果你保持一颗浮躁的心，心中有宏伟的理想却不脚踏实地地去努力整日活在浮躁中，那梦想也只是梦想永远在远方，不会成为现实。
我们都一样，都是心中有理想的追梦人，一起向着那闪耀的光芒不断奔跑，但在奔跑过程中只有睁开你的眼睛勿忘初心才能找到那条通向光明的道路;只有心存信念勿忘初心才能不中途放弃，有一路动力;只有坚持不懈勿忘初心才能直奔梦想;只有脚踏实地勿忘初心才能安心的走到那个光明的世界。不忘初心，一切从现在开始。

we have also come to this hallowed spot to remind america of the fierce urgency of now. this is no time to engage in the luxury of cooling off or to take the tranquilizing drug of gradualism. now is the time to rise from the dark and desolate valley of segregation to the sunlit path of racial justice. now is the time to open the doors of opportunity to all of god's children. now is the time to lift our nation from the quicksands of racial injustice to the solid rock of brotherhood.
it would be fatal for the nation to overlook the urgency of the moment and to underestimate the determination of the negro. this sweltering summer of the negro's legitimate discontent will not pass until there is an invigorating autumn of freedom and equality. nineteen sixty-three is not an end, but a beginning.
those who hope that the negro needed to blow off steam and will now be content will have a rude awakening if the nation returns to business as usual. there will be neither rest nor tranquility in america until the negro is granted his citizenship rights. the whirlwinds of revolt will continue to shake the foundations of our nation until the bright day of justice emerges.
but there is something that i must say to my people who stand on the warm threshold which leads into the palace of justice. in the process of gaining our rightful place we must not be guilty of wrongful deeds. let us not seek to satisfy our thirst for freedom by drinking from the cup of bitterness and hatred.
we must forever conduct our struggle on the high plane of dignity and discipline. we must not allow our creative protest to degenerate into physical violence. again and again we must rise to the majestic heights of meeting physical force with soul force.
the marvelous new militancy which has engulfed the negro community must not lead us to distrust of all white people, for many of our white brothers, as evidenced by their presence here today, have come to realize that their destiny is tied up with our destiny and their freedom is inextricably bound to our freedom.
we cannot walk alone.and as we walk, we must make the pledge that we shall march ahead. we cannot turn back. there are those who are asking the devotees of civil rights, "when will you be satisfied?" we can never be satisfied as long as our bodies, heavy with the fatigue of travel, cannot gain lodging in the motels of the highways and the hotels of the cities. we cannot be satisfied as long as the negro's basic mobility is from a smaller ghetto to a larger one. we can never be satisfied as long as a negro in mississippi cannot vote and a negro in new york believes he has nothing for which to vote. no, no, we are not satisfied, and we will not be satisfied until justice rolls down like waters and righteousness like a mighty stream.

尊敬的各位老师，亲爱的同学们：
大家好！
同学们，我们现在正处在初中阶段，想要做什么事情都应该要去努力了，为自己的未来努力的了。我想同学们应该都有自己的梦想吧，应该也都有想过自己以后要做什么吧，但是我想我们要实现自己的梦想的。前提应该是先有一个好的成绩吧，只有这样我们才有实现自己的梦想的资本，才能够有实力、更轻松的去实现自己的梦想。所以我觉得我们应该要抓住自己在学校里的时间，去为了实现自己的梦想而努力。
现在我们是初中阶段，最应该要做的就是努力的学习了，不管我们想做什么事情一个好的成绩对我们来说都是会有很大的帮助的，我们不应该把自己的时间都用在其它的地方上，用在玩游戏或者其它的对我们的学习没有帮助的东西上，或者是因为自己的懒惰就不去努力的学习，每天只想着玩，这都是不行的。
如果我们在开始努力的之后，也能够坚持下来的话，等到我们从初中毕业的时候，你会发现自己的进步是很大的，不管是学习成绩上还是其它的方面，各方面的能力都会有提高。所以我觉得我们应该要从现在开始努力了，去合理的利用好自己的时间，去努力的学习提高自己的成绩。要做到自己能够监督自己，而不是要老师或者父母时时刻刻的监督你才会认真的学习，这样是没有用的。我希望同学们都能够为了自己的未来而努力。
谢谢大家！

尊敬的老师，亲爱的同学们
大家上午好!
今天我为大家演讲的题目是《健康，是你自己的》。
也许大家都会觉得这个题目很老套，又或者会联想到像霍金、张海迪这些身残志坚的大人物，但今天，我想讲的是我自己。
大家都知道前几天我的脚崴了，也听到有不少同学“不用做操，不用上体育课，真好!”之类的“羡慕”的话语。其实受伤前我也是这样想的，但想现在我就不这么觉得了。
首先是很痛，毕竟脚长在你自己身上，说不痛是假的。这几天晚上我都痛得睡不着，早上早早的就痛醒了，精神也不大好。
其次是不好看，人人都有爱美之心，尤其是夏天，穿的很薄，看着脚上一大块纱布裹着，走路还歪歪扭扭的，心里特别不是滋味。
可能过我的这一番话同学们并没有真正听进去，但是意外是永远无法预料到，我们与其在受到伤害后痛苦，还不如在日常生活中保护好自己;与其哭泣，还不如欢笑!随时保护好自己，是对自己的承诺最后，提醒大家：保护自己，捍卫健康。给自己一个承诺，生命便会还你一片美丽!

亲爱的同学们：
大家好!
在高考中有位考生写过这样一段话：我曾经埋怨过，脚底发黄的布鞋，踏不出青春的活力，直到我发觉霍金转动的轮椅，嵌出深深的历史痕迹;我曾咒骂过，脸边黝黑的胎记，映不出美丽的脸庞，直到我看见全身黝黑的黑人，露出甜甜的美丽微笑……
也许你曾抱怨过上帝是捉弄人的，他对你吝啬幸福，却让痛苦折磨着你，日日夜夜，疲惫不堪，换来的只是滚烫的泪珠。但苦尽甘来后，当你揭开那沉重的幕纱，你会看清，上帝是公平的，磨难也是一种财富。
曾经有人做了一个试验。他点清了一座山林中的红羊后，把山中的狼全部捕捉起来，让红羊没有敌人。照理说，红羊应该是悠闲自得、快乐地生活了，但事与愿违，红羊为了争夺一小片土地、甚至一棵青草而搏斗，由原来一支整齐的队伍变为一盘散沙。经过搏斗的红羊一只只疲惫不堪，过去那种矫健、奔跑如飞的红羊在这座山林中再未曾出现过，而且，红羊的数量也在逐渐减少。是什么原因呢?因为人们捕获了狼，红羊没有了给它们造成生命威胁的动物，而自相残杀直至消亡，失去了危机，同时也失去了生机。可见，在生态环境中，没有磨难就不会有生态平衡的系统。
张海迪胸部以下失去知觉，但这些困难反而使她有了更为远大的目标，学习掌握了德语、日语、英语。她为什么能取得常人都不容易取得的成就呢?因为她在承受巨大挫折的同时，也将挫折化为了动力，让挫折成为自己的奴隶，再一次战胜了磨难。
人生如一块璞玉，这是上帝赐予你最大的财富，这块璞玉中有着酸甜苦辣，也许痛苦过后便是幸福，这是上帝给予你最大的机遇。只有自己努力来雕琢这块璞玉，才能使它成为完美无瑕的艺术品。
同学们，当你遇到挫折、困难时，不妨想想，上帝是公平的，有时磨难也是一种财富。
谢谢大家!

We Are The World ,We Are The Future
Someone said “we are reading the first verse of the first chapter of a book, whose pages are infinite”. I don’t know who wrote these words, but I’ve always liked them as a reminder that the future can be anything we want it to be. We are all in the position of the farmers. If we plant a good seed ,we reap a good harvest. If we plant nothing at all, we harvest nothing at all.
We are young. “How to spend the youth?” It is a meaningful question. To answer it, first I have to ask “what do you understand by the word youth?” Youth is not a time of life, it’s a state of mind. It’s not a matter of rosy cheeks, red lips or supple knees. It’s the matter of the will. It’s the freshness of the deep spring of life.
We all want the future to be better than the past. But the future can go better itself. Don’t cry because it is over, smile because it happened. From the past, we’ve learnt that the life is tough, but we are tougher. We’ve learnt that we can’t choose how we feel, but we can choose what about it. Failure doesn’t mean you don’t have it, it does mean you should do it in a different way. Failure doesn’t mean you should give up, it does mean you must try harder.
As what I said at the beginning, “we are reading the first verse of the first chapter of a book, whose pages are infinite”. The past has gone. Nothing we do will change it. But the future is in front of us. Believe that what we give to the world, the world will give to us. And from today on, let’s be the owners of ourselves, and speak out “We are the world, we are the future.”
