i have the answer to a question that we've all asked. the question is, why is it that the letter x represents the unknown? now i know we learned that in math class, but now it's everywhere in the culture -- the x prize, the x-files, project x, tedx. where'd that come from?
about six years ago i decided that i would learn arabic, which turns out to be a supremely logical language. to write a word or a phrase or a sentence in arabic is like crafting an equation, because every part is extremely precise and carries a lot of information. that's one of the reasons so much of what we've come to think of as western science and mathematics and engineering was really worked out in the first few centuries of the common era by the persians and the arabs and the turks.
this includes the little system in arabic called al-jebra. and al-jebr roughly translates to “the system for reconciling disparate parts.“ al-jebr finally came into english as algebra. one example among many.
the arabic texts containing this mathematical wisdom finally made their way to europe -- which is to say spain -- in the 11th and 12th centuries. and when they arrived there was tremendous interest in translating this wisdom into a european language.
but there were problems. one problem is there are some sounds in arabic that just don't make it through a european voice box without lots of practice. trust me on that one. also, those very sounds tend not to be represented by the characters that are available in european languages.
here's one of the culprits. this is the letter sheen, and it makes the sound we think of as sh -- “sh.“ it's also the very first letter of the word shalan, which means “something“ just like the the english word “something“ -- some undefined, unknown thing.
now in arabic, we can make this definite by adding the definite article “al.“ so this is al-shalan -- the unknown thing. and this is a word that appears throughout early mathematics, such as this 10th century derivation of proofs.
the problem for the medieval spanish scholars who were tasked with translating this material is that the letter sheen and the word shalan can't be rendered into spanish because spanish doesn't have that sh, that “sh“ sound. so by convention, they created a rule in which they borrowed the ck sound, “ck“ sound, from the classical greek in the form of the letter kai.
later when this material was translated into a common european language, which is to say latin, they simply replaced the greek kai with the latin x. and once that happened, once this material was in latin, it formed the basis for mathematics textbooks for almost 600 years.
but now we have the answer to our question. why is it that x is the unknown? x is the unknown because you can't say “sh“ in spanish. (laughter) and i thought that was worth sharing.
When a variety of problems plague the information systems, the critical importance of information security becomes the focus of people's concern. It does deserve the unprecedented emphasis. It is widely accepted that information security, to some extent, outweighs other spheres in the field of information. So the related authorities, enterprises, institutions and organizations place the high priority on it.
Information Security concerns a range of problems- information interception, loss, damage etc. Business and military information leakage will have an devastating impact. For the information owners and monitors, they must drive their efforts to enhance the security protection and maintenance. For example, a strict control over the access to the secret data shouldn't be absent. The network and software provider should take a set of tailored protection measures targeting different computer crimes. The security issues should be also considered at the legislative level, so we are clamoring for a law designed to clamp down on various cyber crimes.
Helloeveryone! My name is Ren Qingwen. I am 8years old. I like drawing, reading, andtelling stories. Today I am telling you a story- The missing forest
Once upon atime, there was a kingdom of forest. Everyone lived there happily. Some werehunting, some were making clothes, and some were catching fishes. Life there waswonderful.
There was alaw in this kingdom -nobody could cut down trees. Once the prince was chasing arabbit and he kicked down three little trees by accident. The king knew it andhe let the guards hit the prince thirty times to punish him.
The king wasvery old. Before he dead, he told the prince his last words,” I am very old now. The forest is our last hope. You willbe the new king. You couldn’t change the law, or a lot of monsters will come! Rememberit my son!”
And shortlyafterwards, the prince became the new king. And the country became stronger andstronger. He was a good king but he still grudged that law!
Oneday, a guest came to the kingdom. He showed the king
a drawing.There were houses and buildings on the picture. The king was vey excited. Andhe decided to listen to that man. He commanded to cut down all the trees. Andhe created a new world! Everyone tried to stop him, but it didn’t work.
Trees werecutting down, animals were running away. Tall buildings were built! At thebeginning, people liked the new city,but later something bad happened. All kinds of monsters showed up: rainmonster, hot monster, wind monster and sand monster. People felt sick with theenvironment, because the new citybrought a lot of pollution. People missed the forest, the animals and thelovely city they used to live in. But they were not able to change it at all.They became homeless and had to abandon their city. Watchedthe image lying before him, the king sank into the seat.
Ladies andgentlemen, from this story we can see that we have to protect our home- theearth, we have to protect the trees, the rivers, the animals and the air, orsomething terrible must happen to us!
It is the onlyearth we got！
That’s all! Thankyou!
Environmental problems are as big as not for individual country orindividual people to address。 In other word， we have reached the stage thatenvironmental problems be solved for international view。 To what extent do youagree or disagree?
In recent years， many nations have bee more aware of the environmentalissues each nation faces， such as air and water pollution。 The question is， arethe environmental issues a national problem or an international problem? It ismy belief that the environmental issues have grown to the point of being aninternational problem needing international cooperation to resolve。
Because of the differences in environmental policies， resources andtechnology， international cooperation could provide quicker results and have agreater impact on bringing resolution to environmental problems for nations ofdiffering environmental policies and of lesser resources and technology。 Bypooling international resources and technology to address the environmentalproblems， the disadvantaged nations are provided the assistance needed。Otherwise their environmental conditions deteriorate ultimately affecting theresources and environment of the world as a whole。
One of the difficulities to an international resolution to environmentalissues is the difference in individual nations view and policies towardenvironmental protection。 In order for international cooperation to occur andsucceed， the nations of the world must submit themselved to internationalstandards and supervision by an international mission elected by theparticipating nations of the world。 All members must agree to abide by thestandards established。
The environmental issues facing each country are not unrelated to the wellbeing of the rest of the world。 The impact is long term and international inscope。 Without international cooperation and agreement to address suchenvironmental issues as glacial melting at the South Pole， depletion of theozone layer， water pollution， air polution， etc。， the environmental conditionsof the world will deteriorate to the detriment of every nation， not just thosethat ignore or lack the resources and technology to resolve their individualenvironmental problems。
As part of the same planet， it is the responsibility of each individual andnation to protect the global environment。 Only international cooperation willprovide the timely solutions and the effectiveness needed to stop thedeteriorating global environment。
failure is the mother of success. sometimes people have to cope with many mistakes and failures in order to reach the successful finals. while others might succumb to failure, they tend to retreat and give in their efforts. success often provides confidence and satisfaction, nevertheless failure companies with bitter, saddness, and suffering. it seems people have to learn through each experience, as success doesn‘t always falls from heaven.
i remembered i used to fail on my vocabury test when i was in high school. i had problem to memorize new words which got lloose each day. i almost decided to give up english, but was obliged to one of my neighbour classmates who kept on sending small sheet for me. in the end of the semester, i found i had finished my vocabulary book which became a work force in reading english. i then realized that a new word came and left our brains for several times. nobody is born as genius for success. success tends to arrive after a serial of trials and failures.
of course, success brings confidence and victory. but, life is not always easy and comfortable. there are more difficulties than eases in the real life. it is likely that we have to face some failures ahead. therefore, those who learn how to deal and endure failures will taste their success eventuallyfailure is the mother of success. sometimes people have to cope with many mistakes and failures in order to reach the successful finals. while others might succumb to failure, they tend to retreat and give in their efforts. success often provides confidence and satisfaction, nevertheless failure companies with bitter, saddness, and suffering. it seems people have to learn through each experience, as success doesn‘t always falls from heaven.

My Family
Everyone has a family.We live in it and feel very warm.There are three persons in my family,my mother,father and I.We live together very happily and there are many interesting stories about my family.
My father is a hard-working man.He works as a barber.
My mother is a woman with a bad memory.She always does a lot of housework,but sometimes she makes mistakes out of carelessness.For example,one day,she washed clothes in the washer,after the washer finished the work,she found she hadn't filled the washer with water.
Now let me tell you a funny thing:one day,father wanted to get up early as usual,buthe wasn't able to do that,because he hadn't set the alarm clock the night before,so when he got up,he did everything in a hurry.After father left,mother said to me mysteriously,"He will come back soon." "Why?" I was greatly surprised."Because today is Sunday,his holiday!" Just as mother said,father came back home soon,and went to bed again--he was too tired.
You see,what an interesting family have!I hope that you will have one like mine,too.
我的家庭
每个人都有家.我们大家生活在那里,并从那里获取温暖.我们家有三口人,我妈妈、爸爸,还有我.我们在一起幸福地生活,我们家有许多有趣的故事.
我爸爸工作认真.他是理发师.
我妈妈是一位记性很不好的人.她总是做很多家务活,但有时却因为她的粗心而做错事.比如说,有一天,她用洗衣机洗衣服,最后却发现自己忘了在洗衣机中放水.现在让我告诉你一件有趣的事：一天,爸爸想像平常一样早起,但是由于他前天没有设置闹钟,所以他起晚了,当他起床时,他匆匆忙忙地洗漱完毕就去上班了,爸爸离开后,妈妈神秘地对我说：“他一会儿一定会回来的.”“为什么?”我十分惊讶.“因为今天是星期天,他的假日.”妈妈正说着的时候,不一会儿,爸爸就回来了,并且再一次上床睡觉了——因为他太累了.
你瞧,多么有趣的家庭!我希望你也有一个像我一样的家庭.
Safety is very important. We often hear people say “safety first”. As a middle school student, we should learn to protect ourselves from every possible danger. Here are some things I do. I hope you can follow them.
On your way to school and home. You should obey the traffic rules. You should walk on the right side of the road. Don’t ride your bike too fast.
During school, you can’t fight with each other. Don’t play with fire. Don’t bring knife to school. Don’t go out of school without your teacher’s permission.
In public places or campus, enough water plugs,extinguishing agents and emergency outlets should be set and prepared for unforeseen circumstances.
Above all,a series of precautions must be taken to guarantee the students' safety. Let's make the campus safe through our long-term unremitting efforts.
Good afternoon, everyone,
The national student sports program, waged by the Ministry of Education and aimed at improving students health, was held from 10：00a.m.~11:00a.m.on April 29，2019 in many primary and middle schools all over China. Almost 11 million students in Jiangsu province participated in this program.
The Ministry of Education advocates that we do exercises for one hour a day and can work healthily for 50 years. Our whole life will be very enjoyable.
In my opinion, we senior high school students should do exercises for one hour a day even though our spare time is limited. Health is a basic condition for our study. If we did not do exercises, we wouldn’t be able to get good study records. So every one of you, join the program now!
Thank you!
It is 4000 years since the Chinese began to grow and drink tea.
There are many kinds of tea in China, of which Longjing Tea is famous all over the world.
Tea is usually drunk in tea sets. A tea set is made up of a tea pot and some teacups, which are both made of china.
Most Chinese are fond of drinking tea. Tea is served not only at tea house and restaurants but also at home. People also drink tea during breaks at offices or factories.
It has been discovered that drinking tea does a lot of good to people’s health. A cup of tea can make you relaxed and refreshed. And it’s said that green tea can prevent cancers. That’s why tea is becoming more and more popular with people.
At last ,I hope you can enjoy Chinese tea.
Skill comes from practice
During the Northern Song Dynasty, there was a skilled archer. One day he drew a big crowd while he was practicing on the drill ground. He shot so accurately that the on-lookers cheered with excitement. He became very proud of his skill. But among the crowd an old oil peddler only nodded his head indifferently. This hurt his Pride.
“Can you do this?” he asked the old oil peddler. “No, I can’t.”
“What do you think of my skill?”
“Just OK, but nothing special. You’ve gained your accuracy from persistent practice. That’s all.”
“What can you do, then?” the old man said nothing. He put a gourd bottle on the ground and covered its mouth with a copper coin. He then scooped out a ladle of oil from his big jar, held it high and began to fill the bottle.
Now, a thread of oil came down from the ladle into the bottle just through the hole of the coin. Everybody looking on watched with amazement. But the old man said, “This is nothing special, I can do this because I have practiced it a lot.” And with these words, he left.
Later, people use this phrase to mean “Practice makes perfect”.
北宋时期，有个技艺高超的射手。有一天，他在训练场上练习射箭，引来了一大群人观看，大家都称赞他的技艺，他感到非常骄傲。但他发现人群中有个卖油翁只是淡淡的点点头，这使得他很不高兴。
他就问那老头：“你会射箭吗?”
“不会。”
“你认为我的技术如何?”
“一般。没什么特别的，你只能对付固定的东西，仅此而已。”
“你会干什么?”
这个老头没有回答。他把一个葫芦放在地上，接着把一枚铜钱放在瓶口。然后从他的大油壶里舀起一勺油。
从高处往放在地上的葫芦里倒。只见那油就像线一样从铜钱中间的小洞里滴下去，一滴都没有漏出来。围观者都惊呆了。而这个卖油翁却说：“其实没什么大不了的，只不过是天天练的结果。”说完，他就离开了。
后来，人们用“熟能生巧”这个成语来表示熟练了就能作得好。
ladies and gentlemen:
my great pleasure to share my dream with you today.i have kept the dream in my mind for so long that whoever in the sun is able to live a happy life for ever.
i think this dream is deeply rooted in the future. as we can see, we are now not far away from violence, poverty, diseases, environmental pollution and even
wars. most of people are in need of what they have never enjoyed. however, i still can stick to my innermost dream, as i still can see the bright lights in
our future. i believe, there will be a day when those from the rich counties are really willing to share what they have with those from the poor countries; there will be a day when we are surprised to find that the word poverty has long been out of our memories; there will be a day when we are together to share our dreams and we will all contribute to making our common dreams come true.
i will not just wait but to take action to live in my dream.
Thank you!
Awesome Love
Good afternoon. Ladies and Gentlemen,
Today I will say something about my family love.
I remember when I was younger. My family lived a simple life. We weren't wealthy by any stretch of the imagination, but we were content with what we had.
Our first vehicle was an old broken-down bicycle. It provided us with transportation on many enjoyable weekends and holidays. Mom sat on the back while Dad pedaled. I, a mere toddler at the time, rode on the bar in front of him. It didn't matter where we were going as long as we were going there together.
Not long after that, my family moved to Hainan. Relying on my parents, courage and persistence, they started their own business. As a result, we were soon able to replace the bike with a new car. So we could travel further on our excursions. Our family's happy laughter filled the car as we traveled to many distant locations in China. Many years have gone by since those happy days, but we're still as close as ever.
Recently, the airplane has become our mode of transportation as we venture beyond the confines of China to see the world. We were able to experience firsthand the uniqueness of Amsterdam, the romance of Paris, and the elegance of Vienna. But yet, such fantastic sites were nothing compared to the love of our family.
Time goes by swiftly, and everything is changing all the time.Yet the love existing in my family always remains. It is the source of our happiness; It,s the source of all of our ideals: confidence, courage, and faith. But it goes so much deeper than that; it warms our very hearts. So I will acclaim for the eternal and awesome love in my family and let it go on forever!
Thank you very much!
亲情
厩得在我很小的时候，家里的日子过得朴实无华，不富裕的家境容不得半点的奢侈。但是，我们对所拥有的一切都感到满足与惬意。
一辆破旧的自行车是我们全家的第一个交通工具。但它为我们带来了许许多多快乐的周末与假期。记得妈妈总是坐在后座上，爸爸骑着车，而丁点儿大的我就呆在车子的前梁上。在我们的短程旅途中，似乎目的地并不是最重要的'，而重要的是我们在一起，享受并渡过了快乐的时光。
在那不久后，我们全家搬到了海南，凭着父母的勇气与执着不懈的努力，他们在自己的事业上很快有了出色的成绩。因此，不久后父母就将原本的脚踏车换成了一辆崭新的小课车，于是，我们就开始了长距离的旅途，在周游中国的同时，快乐的笑声总是充满着整个温馨的车厢。而那些日子虽然已经过去了很久，但是我们还是像以前那样亲密无间。
后来，在我们迈出中国游览世界的时候，飞机又成了我们的新型交通工具。我们全家一起感受阿姆斯特丹的奇异，巴黎的浪漫与维也纳的典雅。但是所有令人心动的景色都不可与旅途中我们全家浓浓的亲情相提并论。
时光如水，我们身边的一切都在无时无刻地改变着，但是亲情不变，永远不变。它是我们快乐的源泉，是我们全家理想、信心、勇气与责任的源泉。它所给予的不仅仅是这些。而更多的是心灵上的温暖与感动。所以，我要为亲情喝彩，让爱--永恒!
爱因斯坦曾经说过：“我认为，对于一切来说，只有热爱才是最好的老师，他远远的超过了责任感。”一个人不论从事什么行业，首先必须热爱自己的职业。只有这样他才会全心全意的投入。而热爱自己职业的动力在于能在工作中得到快乐。
陶行知先生曾对教师职业特征做过这样的分析：教育者应当知道教育是无名无利没有尊荣的事，纯系服务的机会，贡献的机会。而无丝毫名利尊荣可言。现代的教师为适应当前社会的迅速变化，面临许多挑战，如知识结构的更新，教学技术的改进，新型教学手段的尝试，日益难以应付的杂事……为应付这些变化，教师必须付出代价，而付出的代价往往无法获得可见的收益。正因为如此，教师更倾向于从社会地位上而非经济地位上来获得尊严，这也是教师与其他许多职业不同的地方，教师在很大程度上是将自己的精神世界作为职业资源的，并不以实际的可被清点的收益来取胜。那么我们就更应该在工作中寻找快乐。 首先、爱岗敬业是乐教勤业的动力源泉。
教师只有在爱岗敬业，把学校教育工作的发展、国家教育事业的兴旺和自己命运紧密联系在一起的精神指导下，兢兢业业，勤于奉献，淡泊名利，默默的耕耘在三尺讲台之上，而且以苦为乐，甘于寂寞，勤勤恳恳，才能领悟从师的乐趣，才能以从师为荣，以师为自豪。在“爱岗敬业”这种精神支配下，教师也不会视平凡的工作为平凡，不会视琐碎的工作为琐碎，而是会认真对待教育，教学的过程的每一个环节，于细微处显精神，于小事上下。
A Beautiful Doll
Tina is a lovely girl. She has a lot of dolls. One of these dolls is very beautiful. She has long blond hair and wears a white dress. The little girl likes her very much. She called her “Sandy”. You would forget all the sad things and become happy when you see her.
Tina tried to teach Sandy to speak, but she failed. When she is free, Tina always made clothed for her. When she is unhappy or met with some difficulties, Tina talked to her, because they are close friends. What a lovely girl she is! Do you like it, too?
漂亮的洋娃娃
缇娜是一个可爱的女孩， 她有许多洋娃娃。其中有个是很没得：她有着金色的长发，穿着一件白色的连衣裙。小女孩非常喜欢它，因此， 小女孩叫她“桑迪”。当你看到它的时候就会高兴，会忘记所有不开心的事。
缇娜试着教桑迪说话，可她失败了。当缇娜空闲时，她时常会桑迪缝衣服。当她遇到不快乐的事或碰倒困难的时候，缇娜中哦你对它倾述，因为他们是亲密的朋友。多么可爱的一个女孩啊! 你也喜欢它吗?
Dear teachers and students
How do you do! The theme of my speech today is "learning for yourself".
We often hear the saying, "it's never too old to learn." Learning is a lifelong thing, especially for our students, our task is to learn.
Perhaps some students are silently thinking about learning. Alas, what I fear most all day is learning. Learning is very boring and boring. It is a painful thing, let alone happy. But if we study hard and carefully, learning is also happy for us. We should not regard learning as an errand and should not perfunctory it. Only those who want to learn will learn real knowledge and truly realize its happiness.
Students, think about who you study for. Not for teachers, not for family, but for yourself. Think about what we can achieve if we don't study hard.
Let's study hard from now on and build a better future. Study hard and seize the day! Students, let's cheer together!
Thank you. My speech is over.
As we all know, "Failure is the mother of success." But few people canreally understand what the saying means.
In the world, I am sure that no one dare say he hasn't met any trouble allhis life. So we must face failure. In fact, failure is not fearful, butimportant thing is how to face it correctly. Facing failure, people will nevertake their fate lying down.They will try their best to work harder and harderuntil at last they succeed.
Not being courageous to face setbacks, people have no chance to enjoy thepleasure of success. So they have nothing to do but feel sad and empty all dayand all night. In fact, they lose the chance of success themselves.
My friend, whenever in trouble, please remember, "Failure is the mother ofsuccess."
my favourite colour is green,we can see the colour.
everywhere:tree leaves are green,grass is green and so on.green is also a healthy colour,during our lives,we seeing this colour more often is good for our eyes,and why we dont called those natural food like red food,blue food or purple food? so you can understand how impotant it is.green means life,hope youth and etc.thats my favourite colour:green,i hope more and more people will like green like me.
thanks for listing!
My mom is about 45 years old.She has long hair and very big eyes. She is ahousewife. She always helps me with my homework before she cleans the house andprepares dinner for my whole family. She is really a nice and kind mother.
My mom is always very reasonable. All she asks for is for me to complete myschoolwork. If I get a good mark on my test,she will be very happy. If I don'tdo well,she won't get angry. She will encourage me to do better next time.
I love my mom,so I give her a hug when I get home,and tell her she is thebest mom in the world.
As a popular saying goes, "Time is money." But does time definitely mean money? I don't think so. First of all, time is more precious than money. When money is spent, you can earn it back if you want to. However,when time is gone, it will never come back. To some extent, time is priceless. Second, not all time can be turned into money in the end. Some persons are idling all the time. Their time is just for wasting, not for earning money. They will end in nothing at last. So be sure to remember that time can be turned into money only with hard work involved in it.
Good morning everyone!
My name is Jie Lidi. Today, my topic is: “Confidence”. As we all know, failure is the mother of success. But What I want to say is that success is the child of confidence. Without confidence, things can becoenegative and uncofortable.I remember, during an English class, I wanted to make a sentence using the word "listen". I should have said: "I listen to the Voice of America" but I was too nervous and said "I listen to the Noise of America". Everybody in the class laughed. Since then I wanted to train myself to be confident. Now, confidence makes me brave and courageous. Take this speech for example. I wanted to enter this copetition,but I would feel very embarrassed if I made mistakes. Just then, I thought about my dream. My dream is to becoea scientist when I grow up. If I am not confident, how can I overcoedifficulties I face? If I am not confident, how can I succeed in developing myself in the future? I will do it! Today, I am making a speech in public and I feel proud and confident!
I am sure, in the future, with confidence, I will go forward-always forward. Confidence will make my dreams coetrue!
Thank you!
I like spring best of all the four seasons. When spring comes, it's gettingwarmer and warmer, and the world becomes rich and colorful.
The sun is red, the sky is blue, clouds are white, and the trees get greenagain.
In spring, we can see beautiful flowers everywhere. The birds come backfrom the south, and sing happily all day. Everything comes back to lifeagain.
Look, the boys and girls are flying kites by the river happily. Howbeautiful the season is!
individual meters on a county to run the second prize winner in the podium, from the ministers and deputy head of publicity, who took over a certificate of merit and enjoy the award-winning treatment of athletes, the stronger the confidence in the future to participate in sports. this is me, not the end, but a milestone, but also a new starting point.
say, the organization also realized the purpose of running fitness.
How to protect the environment
The environmental protection is the most major problem which in the modern life the humanity faces. must solve this problem must start from foundation. first, must massively propagandize, enhances people's consciousness with understanding, strengthens the environmental protection consciousness. next, must carry on waste recovery use, reduces to forest-tree's felling.
also must strengthen to white pollution processing, little uses the plastic product. finally, must make improvement to clean aspect. causes the city's appearance to be neater. for earth's tomorrow, we must start from the now diligently, will want the well local constable to protect the environment. to this us proposes as follows suggests: implementation trash classification packed in bags.
like this not only can reduce the environmental sanitation worker's work load, but also can even better basically arrive makes use of waste, to reduce the pollution, saves the resources.
thanks!
Protect first wildlife existence environment.Protect a wildlife the most important is to protect their habitats,don't chop down in disorder to fell in disorder,don't at will the heap put garbage,don't abuse agrochemical and insecticide and protect headwaters and air is also one parts which protects habitat.Secondly and not and over catch to over kill a wildlife,don't participate an illegal business wildlife,see the illegal immediately reflects toward the wildlife association or the forest public security official's organization.Again take out our benevolences and courage,the person who advises Zu close relatives and surroundings refuses to eat game,don't go to game restaurant to have a meal;For use the ware that the rare wildlife do,such as the fur-lined jacket,drugs,tonic...etc.,should also determinedly boycott.End,aggressive publicity protection wildlife of important meaning,start to do from I,start to do from the family,start to do from now,develop to respect all the moralses of the lifes view hard.
首先,要保护野生动物生存环境.保护野生动物最重要的是保护它们的栖息地,不要乱砍乱伐,不要随意堆放垃圾,不要滥用农药和杀虫剂,保护水源和空气也是保护栖息地的一部分.
其次,不滥捕滥杀野生动物,不参与非法买卖野生动物,见到违法者立即向野生动物协会或森林公安机关反映.
再次,拿出我们的爱心和勇气,劝阻亲人和周围的人拒食野味,不去野味餐馆用餐;对于用珍稀野生动物做的制品,如皮衣、药品、补品等,也应坚决抵制.

Good morning everyone,
today is my turn to the speech. First of all, I would like to say that a quick test, we hope that the good preparation, good test for all, is the only way home for a good year. My English is not high, I wish I could within the next two years to learn English well. I hope you will be able to learn English after graduation to have a good future.
Finally, I wish the students and teachers a happy new year, further study and work. Well! I finished the speech. Thank you for listening.
Never Say Die
"never say die, i've been down this road before. i'll never quit, i'll never lay down." it's the song named "win". it tells us never say die.
seeing this topic, what first strikes my mind is the group of blind football players who won the silver medal at the beijing paralympics games. what they did shows the spirit of the old saying “never say die”. instead of giving up because of their blindness, they have redoubled their efforts and they did wonders.
never give up, even though there are many difficult things waiting for you. if you try your best, maybe there will be many successes behind you the next time.
i once read a book called "the count of monte cristo". in the book, it says, all human wisdom is summed up in these two words, wait and hope. just try your best, wait for the success and hold on your hopes.
trying times will pass, as they always do. face the trouble heroically
and just have patience, your dreams will come true and you will surely win.
Good afternoon,everybody：
It is really a great honor to have this opportunity to make a speech for topic is OUR CLASS,OUR FAMILY.
I love my class very much!On one hand,I think we’re a struggling team,although we’re not the best class in study,we’re the hardest far as I’m concerned,our classmates all like studying very the other hand,we’re a unitive the military training for example,It is well known that military training needs good we did it,so we won the second prize.
This is our class,a harmonious class.
Okay,that's all for my ks for listening.
Youth is not a time of life, it is a state of mind ; it is not rosy cheeks , red lips and supple knees, it is a matter of the emotions : it is the freshness ; it is the freshness of the deep springs 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 .
When the aerials are down , and your spirit is covered with snows of cynicism and the ice of pessimism, then you are grown old ,even at 20 , but as long as your aerials are up ,to catch waves of optimism , there is hope you may die young at 80. Thank you!
青春
青春不是指岁月，而是指心态。粉嫩的脸，红润的唇，矫健的膝并不是青春。青春表现在意志的坚强与懦弱。想象的丰富与苍白、情感的充沛与贫乏等方面。青春是生命深处清泉的喷涌。
青春是追求。只有当勇气盖过怯弱、进取压倒苟安之时，青春才存在。果如此，则60见之长者比20岁之少年更具青春活力。仅仅岁月的流逝并不能使他们衰老。而一旦抛弃理想和信念，则垂垂老也。
岁月只能使皮肤起皱。而一旦丧失生活的激情，则连灵魂枯老，使人生枯如死水，毫无活力。
60岁长者也好，16岁少年也罢，每个人的内心深处都渴望奇迹，都如孩子一般眨着期待的双眼，期待着下一次，期待着生活的情趣，你我灵魂深处都有一座无线电中转站------只有你我年轻，则总能听到希望的呼唤，总能发出喜悦的欢呼，总能传达勇气的讯号，总能表现出青春的活力………
一旦青春的天线倒下，你的灵魂即为玩世不恭之雪、悲观厌世之冰覆盖;即使你年方20.其实你已垂垂老也。而只要你青春的天线高高耸起，就可以随时接收到乐观的电波-----即使你年过八旬，行将就木，而你却仍然拥有青春，你仍然年轻。
Three years ago, when Tyrone Duncan was jobless, recovering from a spinal injury and a stintin a homeless shelter, some volunteers at his transitional housing site encouraged him to run with them as they trained for a race.
So it’s no surprise when Duncan says running turned his life around. He is far from the only person in sneakers to make that claim. A growing number of national organizations are using the sport to help kids and adults facing such challenges as homelessness, drugs and cancer. They have a variety of names — Back on My Feet, Achilles International, Alex’s Lemonade Stand, Run to Recover — but all have turned to running for the psychological and physiological benefits that training for a race can bring.
