today i'm glad to be here to talk about what i'd like to invent - a chair that's good for students' health. it will be made of wood. there will be two sensors in it -- one on the seat, and the other on the back of the chair. when the student doesn't sit straight, the chair will remind him .if he sits on the chair for over one hour ,it will make a noise. it won't stop until the student stands up and leaves.

今天我很高兴到这里来谈论我想发明——一把椅子,对学生的健康有好处。这将是用木头做的。将会有两个传感器，一个在椅子上，另一个在椅子后背。当学生不坐直,椅子会提醒他。如果他坐在椅子上超过一个小时,这将发出噪音。它不会停止,直到学生站起来,离开了。

it will be a useful invention, won't it ?

这将是一个有用的发明,不是吗?

thank you!

谢谢大家!

i have a question for you. squo;do you know how to breathe?squo; okay, i know what you are thinking now, girl, are you kidding me? everybody knows how to breathe. actually, if i were you sitting down in there one year ago, i would think, how did she make it to the final?

alright, seriously speaking, what i am talking about is the art of breathing, and itsquo;s about breathing in a yoga way: peacefully and always under control. what it reveals is the real essence of perseverance, in order to achieve, sometimes, you need to wait. and when it comes to things you really want in life, it is as hard as it could possibly be.

for me, singing is a life thing. when i am singing on the stage, i feel whole-heartedly involved, and the self-fulfillment it renders is inexplicably thrilling. but with all the realistic problems i need to face in life, all those i want seem too far to be true– so far that i am terrified that i will never ever be able to get there and that gradually i will be carried away by the currents and torrents of life. isquo;ve been drowned into this ambivalence for so long. now, with a refined perspective towards self-realization, i am waiting, in a graceful posture, and knowing that i am going to get there. and on this, i should say, i owe yoga a thank-you.

i still remember, about one year ago, i attended a yoga course for the very first time. and to tell you the truth, i went there for a nice figure. however, after practicing for some time, i discovered that there was an ineffable inner-strength burgeoning sneakily in me while i totally focused. in order not to let go this significant power, i started to picture all i wanted in my mind while i was fully concentrating, for i believe the wings of imagination could make things possible. i learned to breathe with my dreams, shaping the eagerness into this elegant gesture of persisting.

and now, if you ask me what exactly is the art of breathing, i would say it is indeed the art of living. it combines the search of balance, the grace of patience, and the awareness of appreciation.

so even though feelings are tied up with life routines, i could still hold onto that free ego which i have always adored: the girl who is singing under the spotlight, with all her heart and soul; the girl who is persevering with all she believes in and always feels grateful for what has been bestowed on her.

that girl is now standing right here in front of you, hoping that you are all as lucky as she is, living with dreams and love. no matter how tough things get, i tell myself, i tell myself that, every single thing i am doing now is every step closer to that very moment of my trajectory, just like every yoga breath to every blossom moment of my life.

“科学”是一个很深奥的东西，它就像是一个比宇宙无数倍的海洋，我们就像是海中千万个生物之一。每一天，我们都在这片海域中探索、发现这样更有利于我们人类增长知识，特别是那些知识领域的先驱者——科学家。更是在不断更新着我们的环境，这样才会有更美好的生活。

在二十一世纪里，科学将会成为人类的生命。你不懂科学，就无法在这个社会里生存。如果你有了科学的种子，精心培育，随着时间的推移，这颗种子就会不断生根、发芽、结出累累硕果。而“诺贝尔奖”就是为了奖励那些用自己的智慧和辛劳培育出累累硕果来造福人类的科学家的，让他们成为我们的骄傲，成为我们学习的榜样。同时更是激励他们为我们甚至全人类作出更杰出的贡献。有20多个国家，466名科学家获得过诺贝尔奖，当他们走向“诺贝尔奖”的领奖台时，他们代表自己拥有了科学创造的巨大财富。也代表着他们为人类作出的贡献，我们要为这些人喝彩，欢呼是他们用科学改变了世界。

科学的力量是无穷无尽的，它会给你带来意想不到的财富。，所以，我们因当从小就热爱科学，但你如果不去深入挖掘科学中的奥秘，不去实践，你将永远不会得到科学的幸福。有些人只知道其一而不知道其二，了解了表面，而没有深入的去探索，这样怎能获得成功呢?因此，我们要勇于尝试，创新。用于推翻前人的话、结论。而最终得到的就是自己的成果。

诺贝尔科学奖到底离我们还有多远呢?不用问了，只要你从小播种下科学的种子，努力学习，它就在我们的身边。

今天，我来到了厦门科技馆体验了我国古代四大发明之一的印刷术。

开始，有一位漂亮的工作人员姐姐给了我一张既奇怪又难看的纸张，她让我先把黑色墨水抹在一个正方形的木板上，她说：“你要反复地不停地抹，不要留空隙，知道了吗?”“知道了”!我极不情愿地回答。我心里愤愤不平地想，你把我当成保洁员了吗?让我在这里不停地刷洗，我边想边极不情愿地来回刷。终于，她叫我停了下来，我以为就这样结束了，这时，工作人员又递给我一个酷似油漆刷的刷子时，我忍住了心里的怒火，难道你又把我当成“粉刷匠”了吗?这时，姐姐好像看出了我的心思一样，微笑着向我起来，她拿起我的手，手把手地教我做一名粉刷匠，她握着我的手在木板上左刷刷，右刷刷，刷到差不多均匀的时候，姐姐让我停了下来。

最后，开头时姐姐给我的那张纸终于派上了用场，姐姐叫我把那张纸平铺在刚刚刷过墨的木板上，再用干净的刷子马不停蹄地刷啊刷，当所有的工序都完成后，我深深地吸了一口气。这时，我不经意地朝那张纸瞟了一眼时，我惊讶地张大了嘴巴，原来那张白色的纸上印了唐代诗人柳宗元的一首山水诗《江雪》。

啊，太神奇了，我一直以为字只能用电脑录入，打印机打印，原来还可以这么神奇的复印出来。

这时，姐姐及时地给我科普了关于印刷术的有关知识，中国的印刷术，源远流长，传播广远。它是中华文化的重要组成;它随中华文化的诞生萌芽，随中华文化的发展演进。如果从其源头算起，迄今已经历了源头、古代、近代、当代四个历史时期，长达五千余年的发展历程。早期，中国人民为了记载事件、传播经验和知识，创造了早期的文字符号，并寻求记载这些字符的媒介。由于受当时生产手段的限制，人们只能用自然物体来记载文字符号。例如，把文字刻、写在岩壁、树叶、兽骨、石块、树皮等自然材料上。由于记载文字的材料十分昂贵，因此，只能将重要事件做简要记载。大多数人的经验，只能靠口头进行传播，这严重影响着社会文化的发展。

公元1041~1048年，平民出身的毕昇发明活字印刷，提高了印刷的效率。但是，他的发明并未受到当时统治者和社会的重视，他死后，活字印刷术仍然没有得到推广。他创造的胶泥活字也没有保留下来。但是他发明的活字印刷技术，却流传下去了。

这次的体验让体会到了我们中华古人的智慧是多么强大!我一定要好好学习，学习更多地科学知识。

east and west have met

runner-up: rui cheng gang, foreign affair college

honorable judges, ladies and gentlemen:

kipling said:" east is east, and west is west, and never the twain shall meet!" but now, a century later, they have met.

they have met in business. they have met in education. they have met in the arts.

some would argue that these meetings leave us with a choice between east and west ,but i believe the best future lies in the creative combination of both worlds. we can make western ideas, customs and technology our own, and adapt them to our own use. we can enjoy the best of all worlds, because our tradition is, above all, one of selecting the best and making it our own.

but, do western styles and values threaten our identity?

history makes it easy for us to think so-perhaps too easy.

some people seem to think that adopting western customs, such as a bride wearing white-which has long been a color of mourning in china, instead of the traditional chinese red for her wedding, is another submission to foreign intervention,--a betrayal of our heritage, they say.

they fear that as we become "globalized", we will no longer be chinese.

i do not agree.

history teachers that a strong and confident nation is at ease in hearing from the outside world.

the wedding of eastern and western cultures, whether in white gowns or red, brings us variety.

it is a rich banquet of special foods from all over the world.

as an amateur gourmet of chinese cuisine, our superb flavours delight me.

but my chinese taste appreciates food from any land.

i even allow the convenience of mcdonald's a place in my life without giving up my good taste.

my grandfather taught me to hum tunes of beijing opera from the time i was very young; they are deep in my spirit, part of my soul.

i love beijing opera, because it always reminds me of who i am.

but i am also a fan of modern pop music, the no.1 fan of spice girls on campus.

of course, it goes far beyond food, music and dance. it goes into values and ways of thinking about the world.

once upon a time, or so my teacher told me, a chinese boy and an american girl had a squabble.

both wanted to keep a bunny rabbit they had found in the garden.

surely you've seen a rabbit sunning himself in the grass.

nothing is more lovable, nothing more natural. no wonder they wanted him. the chinese boy played his er-hu. happiness and joy, longing and passion, filled the air. the little rabbit swayed gently and began to move his ears in the direction of the music. he liked what he heard.

the girl then took out her violin and played it to produce beautiful melodies of her own.

the rabbit began to bounce in her direction.

so intent were the children on their own music that neither paid the other any attention.

the competing melodies confused the little rabbit and he did not know which way to turn .unable to attract the little creature, both children gave up ;they walked away, in different directions, leaving the rabbit. . .alone.

but, what if they listened ,what if they really heard each other's music, instead of always playing their own tunes?

when i hear the music of a violin ,rich with the joys of men and women who came together and sang and danced.. . i hear echoes of the music of the grass lands, of the hills, of the rivers...of my own native land.

is music mine and yours, or is it ours?

what i want to hear is the er-hu and the violin played together, in rhythm and in tune. together, we can produce new and beautiful music, rich with textures and sounds that can only be made in harmony.

the rabbit sits in the grass in the ever-warming sun. waiting for us to play, waiting for the symphony to begin.

will he have to wait forever? the choice is ours . thank you.

尊敬的评委、女士们、先生们：吉卜林说过，东方是东方，西方是西方，两者永不聚!然而如今，在一个世纪之后，东西方相聚了。

它们在贸易中相聚，在教育中相聚，在艺术中相聚。

有人争论说这种东西方之聚,使得我们能够在东西方中作出选择.然而我相信最美好的未来在于东西方世界的创造性的结合，我们可以变西方的观念、习俗、技术为己所有，为己所用;我们可以享受两上不同世界之精华，总之，我们的传统之一就是择其精华，为己所用。

然而，西方的生活方式和价值会威胁到我们的民族特色吗?

历史让我们轻易相信——也许是太轻易地让我们相信此说了。

有人似乎认为彩西方习俗，比如新娘结婚穿白色婚纱，是对外国介入的屈服，是对传统遗产的背叛，因为按中国传统，结婚新娘要穿红色，而白色长期以来代表的是哀悼。

这些人担心一量我们变得全球化，我们也就不在是中国人了。

我不这样认为。

历史告诉我们：一个强大自信的民族学起外面的世界易如反掌。

无论是穿白衣还是黑衣，还是东西方异质文化的联姻，都给我们带来多姿多采的生活。

东西方异质文化的联姻是一席来自世界各地佳肴的盛宴。

身为中国菜的业余美食家，我喜欢民族的佳肴。

然而我的中国口味也欣赏异国的风味。

生活中我为简便吃麦当劳，却不会放弃自己的良好口味。

从小祖父就教我哼唱京剧，京剧深入我的精神之中，成为我灵魂的一部分。

我热爱京剧，因为京剧让我总想起自己是谁。

但是我也迷恋现代流行音乐，在学校里还是辣味女孩的头号歌迷。

当然，异质文化的交流远不止于食物、音乐和舞蹈，它深入到价值观和世界观。有一次老师给我讲了一个中国男孩和一个美国女孩发生争执的故事。

在花园里他们俩发现了一只小兔，两人都想要。

你肯定见过草丛中晒太阳的小兔。

没什么东西比小兔子更可爱的，更富有自然情趣了，难怪他们两人都想要它。

男孩拉起了二胡，愉快喜悦的琴声，充满了渴望和激情，回荡在空中，小兔子听着这音乐轻轻摇摆，耳朵转向音乐，它喜爱男孩的琴声。

女孩也取出小提琴，拉出悠扬的旋律。

小兔子听了朝她跑去。

两人都全神贯注于自己的音乐，丝毫没注意对方演奏的音乐。

交杂在一块的音乐困惑了小兔子，它不知该朝哪走。男孩和女孩都不能将小兔子吸引过来，只好放弃，各自走开了，扔下小兔子独自一人。

然而倘若他们倾听对方的音乐，而不是各自为歌，那么结果会如何呢?

当我听到小提琴声响起，男男女女走道一起又唱又跳，乐声中充满了欢乐，此时我也听见了草原上、山谷间、小河旁传来得我们本民族的音乐的回声。

音乐分你我，还是属于我们大家?

我想听的是二胡与小提琴的合奏，旋律与节奏和谐一致。

大家一起才能创造出新颖动听音乐，只有在和谐中大家才能创造出富有神韵的乐声。

在温暖的阳光中，小兔子在等待着我们一起演奏，等待着交响乐开始。

他有必要再永远的等下去吗?决择在于我们自己。谢谢。
