Pollution is something that is threatening all Human beings.There are more and more fuel being used and the Earth becomes too lazy to work.As the same time,many natural disasters are threatening Human beings too.For example,Earthquake,Flood,Lack of Water,Acid Rain and etc.We should do our best to protect our environment and leave a better place for our children and our grandchildren.Many people are complaining about the air quality in our country.We should plant more trees.We should not step on meadows and we should not litter behind us.If all the people can do these things,i am sure our pollution will become less.And our Earth will be a wonderful place not only for human beings but for all creatures to live on.

As we can see from the picture.
Base on allthe analysis above,some measures can be recommended as follow.

爱地球谈环保
正所谓“地球是我家,整洁靠大家”,身为地球人的我们有义务,有责任去保护它.但是我们的地球真的生病了.
地球开始患上感冒的病症了,它开始发烧,这是为什么呢?就因为无良厂商任由工厂排出绵延不断的黑烟.现在就连我们坐在飞机里时,所看到的房屋都变得跟蚂蚁一样小,而我们依能凭着那一团团的黑气团认出工厂的所在地.不断向大气扩散的烟使到地球体温升高,可见得地球是不可能在短期内退烧的了.
身为地球的保护层－臭氧层亦破了个大洞.这就是地球人所作所为,造成的极大祸害.冰箱、冷气等释放的化学物质,工厂及汽车排出的黑烟等都是足以侵蚀臭氧层的根源.
我们的地球已经进入了病入膏肓的状态.后知后觉的地球人,直至近几年才大力鼓吹环保运动,但却不见有任何的改善,正所谓“江山易改本性难移”,或许我们需再花上一个世纪,甚至几十个世纪的时间才能有效的拯救地球吧.
如果就连身为地球人的我们都不珍惜、爱护地球,那这工作将由谁来做呢?环保工作其实并不难,只要全世界的人一人捡一份垃圾,那么这地球就会干净多了!
Love the earth talk about environmental protection
Is the so-called" the earth is my home,clean on all",as the people of the earth we have an obligation,have the responsibility to protect it.But our planet really sick.
The earth began to suffer from cold symptoms,it begins to have a fever,is this why?Because unscrupulous vendors at the stretch of black smoke from the factory.Now we even in the plane,see house become like an ant is small,but we in with the round that black air recognized factory.To make the earth atmospheric diffusion of smoke temperature,so the earth is not possible in the short term the fever.
As the earth's protective layer ozone layer also broke a big hole.This is the earth the doings,causing great harm.Refrigerator,air conditioning and other chemicals that are released,factories and cars emit black smoke is sufficient to erode the ozone layer of.
Our earth has entered the state regarded as hopeless.After becoming aware of the earth,until recent years vigorously advocated environmental movement,but did not see any improvement,is the so-called" leopard change his spots",we may need to spend the last century,even a few centuries to effectively save the earth.
If even the earth we do not cherish,cherish the earth,the work who will do?Environmental protection work actually not difficult,as long as people all over the world to one person to pick up a garbage,then the earth would be much cleaner!

Good morning,everyone!I feel quite honored to be here to give you a speech.Today I'd like to talk something about my childhood.
I had an unforgetable childhood,though it was very hard .My parents are farmers,they always work very hard to support the family.I remembered that I was locked in the home while they went to work in the field,as they wanted me to keep off the river.I was also badly beaten by my father for being rude.I will never forget the scene that my parents working in the field till the sunset.
It is not easy for me to express my feeling about my childhood,I was tought to be a good person by my dear parents.Though they didn't give me any materia enjoyment,they tought me to be honest,to be kind-hearted,to smile at the world,most of all,to be gratitude to everything.
That is what I want to say today.life is so wonderfull,I hope everyone of you can enjoy it,no matter if you are rich or not.Thank you for listening!

　　善待失意
　　安徽一考生
　　人生得意,可歌可贺；人生失意,亦需善待.人生难免不如意,要每个人的一生中,随时都会碰上湍流和险境,如果低下头来,看到的只是险恶与绝望,在眩晕之中失去了生命的斗志.就使自己坠入地狱里.而如果我们若能抬头,看到的则是一片辽远的天空,那是一个充满了希望的并让我们飞翔的天地.
　　人生像是一条水流,历史就像是融合了许多水流的大江.你无法离开大江,但你又发现大江里布下了一些礁石,大江上或有着狂风,江水流着流着会出现急剧的转弯、急剧的下降和攀升,以及歧路和迷宫.
　　人生好像一艘船,世界好像大海,人自身好像是开船的舵手,思想的倾斜与时代的选择好像时而变化着走向的水流、或大或小的风.
　　在成长、学习、工作、生活诸事中,我们不可能花好月圆,一帆风顺,而没有失意和挫折.总会遇到这样那样的、或多或是少的失意,如考试失利,仕途无望,商海折兵等.倘若我们在失意时浑浑噩噩的、一蹶不振,只会失意又丧志,最后亲手葬送了自己的前程.而失意的过程往往就是获得真知的过程,如果我们从中分析原因,吸取教训,完善自己,避免今后再走相同的或相似的弯路,那你已实实在在地踏上了成功的路.
　　其实,失意不是人的必需,而是人的必经.因为不经风雨怎见彩虹,你没受过风浪的冲击,你的意志就得不到锻炼,心灵就蕴携不了艰难困苦的洗礼.俗话说“大树底下长不出好草”.任何一个人想成就一番事业,就须迎击生活风浪,笑傲风云,因为有挫折才会奋起,有失意才会求荣.不要因一次挫折而折断人生奋进的脊梁,也不要为一次的失意而放弃人生的追求,而应“吃一堑长一智”,在痛苦的磨难和调整中向新目标冲刺.
　　面对失意,不能失志.燕子去了,有再来的时候；杨柳枯了,有再绿的时候,桃花谢了,有再开的时候……调整自己的心态和情绪,扬起前进的风帆,校正人生的坐标和航线,重新寻找和把握机会,找到自己的位置,自己的光源,自己的声音……创伤就是前进的动力,挫折就是生命的财富.
　　我用过的,很不错的!加油哦

I enjoyed every single second on the stage
It all happened as if it was yesterday. I can still remember the exact moment when Zhao Yinqi said that all of the six votes were for me. Many people say that I didn’t react much to that announcement. Well, it’s because I couldn’t believe my ears! I was waiting for somebody to wake me up……
Anyway, the competition started a long time ago in April. Since it’s the first time for me to take part in the competition, I had a really hard time through the whole thing. Back in April, when my teacher first told me that I was gonna sign up for the 2007 Star of Outlook English Talent Competition, I hesitated. Because I’m a junior 3 student, and everybody knows that Zhongkao was coming up! It was a way too risky for me. I could lose in both events. But with the school and my parents supporting me, I entered the competition and finally was ready to rock n’ roll. It was quite hard for me at school where I had to both study hard and prepare for the competition. The good thing is everything went along quite smoothly in Ningbo. I successfully entered the finals of the competition in Zhejiang province. There I saw many great English speakers and made friends with some of them. As far as I know, quite a few of them had taken part in the competition for a few times already. They said that I must have been a lucky dog to come this far in just one try. Therefore, I had the motivation to go further and give it my best shot. Just when I was so excited that I won the top grade prize in Zhejiang province and was permitted to go to Beijing for the national finals, I had to deal with one of the most difficult problems. The thing is that I had to take part in Zhongkao on June 15, but I have to be in Beijing by then if I made it to the finals. The schedule clashed together and I was at the edge of the cliff. My parents said that I could come back again next year and should be preparing for the exam right away. I thought I was ready to say goodbye to the competition. On the other hand, my teachers and classmates are definitely with me on this one! The principal even went to the school board himself and applied for an exam-free certificate in order for me to go to Beijing without any worries about Zhongkao. Therefore, my parents had no reasons for not supporting me to go to Beijing and go on with the national finals.
The semifinals started on the 9th of June. The first round was the written test. It wasn’t as bad as I thought, I got a 90! There’s nothing much to talk about the exam, but the first round is where I first met all of the contestants. I soon made friends with Mike (contestant 14) and Li Siyao （contestant 11）from Sichuan province. They were both great English-speakers, and we all made it to the top 10 together.
Now, I’m not gonna go into the details about the PK rounds or how I promoted. I’m sure you’ve watched the whole competition on TV, and therefore you’re probably clearer about the whole process than I am. Anyway, here I’d like to share something that cannot be shown on TV but something you can only feel when you’ve actually taken part in the competition. First, I wanna emphasize that this is not just a competition about how well you speak English, but about how you express yourself, your personalities and characteristics through this beautiful language. To tell the truth, when you are at top 10, there’s not much of a difference with your English speaking skills between the contestants. Some of you might say that I’ve been to Canada for 3 years and that must have been unfair to the others. What can I say, Rick (contestant 18) the runner-up has been to USA for 8 years, and I don’t think it affecting much. Because going abroad is just another way of learning English, that’s all. And the other contestants who’ve gone to EF to learn English speak English just as well! Back to my point, the top 10 contestants are all winners at how well they speak English.
Second of all, I just wanna say: I love the game! I enjoyed every single second on the stage. Though I’m probably the one who gets to go on the stage the least (I’ve never PK-ed before), I still loved the process. The experience of this competition definitely beats being the champion, and I’m not just saying that! I’ve learnt so much through this……Without my parents here, I got to know how to take care of myself, how to be more independent. Though they missed out upon my glorious moment of standing on the stage, it’s still worth it. Spending the two weeks with my new friends, I also learnt how to get along well with others, how to be approved by others. When we were at top 8, we had to rehearse a dance like a cheerleading squad. We had some difficulties through that, because everybody’s got their great ideas that we all liked to share. And when great ideas come together it’s hard to get settled. But, we finally overcome all the obstacles and created a fine dance routine. Through this short time period, I finally know how to deliver what I wanna say in the most friendly way which doesn’t hurt anyone’s feelings and is easier for me to communicate with others. Top that, I seemed to be a big sister in the other contestants’ minds. I’m really happy to have friendships with Li Xiang, Wang Beibei, L. Angel, Mike, Rick, Liang Chen, Jenny ( I could go on and on and on)……I’ll always remember the good times we had together!
Taking this chance, I’ll answer a question that a lot of people are asking: what exactly is the key to winning in a competition? Well, if you watch the show carefully, you’ll find that every time when we had to say a few words before the round starts, I always say that I’m gonna go on and have fun. That’s right! Just enjoy yourself. Don’t think about the results, there’s no need! And you can’t do anything about it either. So just be yourself, treasure this once in a lifetime opportunity and have fun! I don’t know if it’s a really good answer, but I guess you’ll never know the feeling until you actually try it. (I’m gonna be a little advertisement here) Come on and join the Star of Outlook English Talent Competition next year! I’m sure you’ll love it as much as I do. And you know what? It’s such a coincidence that the champions of the last 3 annuals (Lisa Wu, Lucy Chen, and me) were all contestant No. 4! See if we can keep this record. Just kidding, good luck to all the contestants next year!
I guess there’s this one part that every champion can’t skip--- the thank-yous. Here it comes……
First of course, I have to thank my parents. Even though you didn’t go to Beijing with me, I always believed that you’ve made the right choice. I experienced something that most of the other contestants didn’t have. I love you both!
Second, it comes to the big thanks to my teachers.
Thank you Mr. Zhang Qingsen, without your training and support I wouldn’t have even stepped out of Ningbo, I’m looking forward to working with you again.
I also have to thank Mrs. Xu, my homeroom teacher, and all the other teachers who supported me and encouraged me through the whole competition, even though they were so busy with the other students facing the big task of Zhongkao.
I’ll never forget you guys, don’t worry--- Class 306
I’m not gonna write out every single name like you asked me to before I went to Beijing. But still, thank you guys (He Mengsi, Zheng Lin, Chen Jialong, Jin Ke, Zhou Kaibo……) soooo much for calling and text messaging to encourage me! I really loved our class. All the great memories we had together, I’ll treasure it forever. Even though we are gonna be separated for not being in the same class anymore, I know we’ll all miss our home---class 306.
Now I’d like to thank the new friends that I made who I came to Beijing with from Zhejiang province. They are the ones who didn’t make it to the finals but whose hearts were with me the whole time. Thank you so much Newman, Pan Meng, Gao Zheng, Fisk, Hong Shengkai……you are the ones who let me know what friends are for and that new friends could be as cool as the old ones.
Finally it comes to the last two persons. My big “twin sister” Kane, and my team leader Tina! They are like a family to me when I was in Beijing. Kane is the runner-up of the adults group (and was soooo close to making the champion. Oh yeah, you don’t know how close it was. Ha!). She’s also my roommate. We had great times and even sang out loud together at midnight. A lot of people say that we’re like real sisters and we did look like each other. We even have the same last name Wu. Well, I just wanna thank you Kane for being there for me and making me feel like at home. Tina, don’t get me wrong but you are really like a mom to me, though you do look more like a sister. Thank you for taking all those great photos for me and I loved the times we had at the World Park. I’ll miss you two! Keep in touch……
Well, I gotta come to a stop, or else the whole book is gonna be about me! Nothing much left to say though (a good sign), I just wanna wish every contestant a good luck next year, and DO enjoy every single second of this competition. I’m looking forward to seeing more stars of outlook……
