When I went to middle school, it was hard for me to adjust the new

environment at first, because there were so many subjects to learn, I fell

behind other students. I did not know what to do, I just wanted to get away from

school. I talked about my annoyance to my friend, she told me that I got too

much pressure and she suggested me to take relax and made progress step by step.

She said everything would be better someday. Now I have made progress and when I

look back on the passed days, it was just a small problem for me. I got over the

hard moment and become a strong person.

Youth Day (青年节) in the Peoples Republic of China is on May 4. It was established in December 1949 by the Government Administration Council to commemorate the beginning of the May Fourth Movement in 1919. This day is known as …

May Fourth Movement

Chinese intellectual revolution and sociopolitical reform movement (1917 – 21)。 In 1915 young intellectuals inspired by Chen Duxiu began agitating for the reform and strengthening of Chinese society through acceptance of Western science, democracy, and schools of thought, one objective being to make China strong enough to resist Western imperialism. On May 4, 1919, reformist zeal found focus in a protest by Beijings students against the Versailles Peace Conferences decision to transfer former German concessions in China to Japan. After more than a month of demonstrations, strikes, and boycotts of Japanese goods, the government gave way and refused to sign the peace treaty with Germany. The movement spurred the successful reorganization of the Nationalist Party and gave birth to the Chinese Communist Party. See also Treaty of Versailles.

Ladies and gentlemen,

I feel it a great honor to have a chance to give a speech here, talking about the haze weather, which causes lots of bad effects on our health and life. We breathe polluted air, making us suffer from lung and liver diseases. Besides, because of it, the flights have to be canceled. All kind of transports may run into each other, resulting in much damages and lots of injuries.

As far as I am concerned, it is high time that we did something. As individuals, we should ride the underground or buses instead of cars to reduce carbon dioxide. As government, more measures should be taken by carrying out the related law on pollution.

In summary, we re all looking forward to breathe fresher air and live a happier life. Everyone should be a part of this job.

Thank you for your listening.

女士们和先生们，

我很荣幸能有机会在这里做演讲，和大家谈谈这给我们健康和生活带来不好影响的灰霾天气。我们呼吸这被污染过的空气，让我们遭受肺、肝疾病。另外，由于这天气，航班被迫取消。各种交通工具相撞在一起，造成很大的毁灭和伤害。

我觉得是时候我们该做些什么了。我们应该乘坐地铁或公共汽车而不是汽车来减少二氧化碳。政府应该实施更多针对污染的相关法律的。

总之，我们都盼望着能呼吸到更新鲜的空气，过着更快乐的生活。每个人都应该参与进来。

谢谢大家的聆听。

我相信在我们还是小孩的时候，我们就被教导要学会与人分享。起初，我不是很明白。

但现在我慢慢地了解了。分享快乐会让我更加快乐，而和朋友分享我的悲伤也会减轻我的悲伤。

当我告诉我的朋友我在朗诵比赛上取得第一名的时候，他们都向我表示祝贺，并说了很多好话，这让我感到更开心。

当被老师责备时，我告诉我的朋友，说出来能让我感到舒服。此外，他们的安慰也能让我感到更舒适。

更重要的是，分享我的经验给他们，能够帮助他们使我感到很满足。不管怎么说，与别人分享我的情感，事情让我觉得很棒。你最好也努力尝试着分享，之后你就会明白了。

[高中英语作文：分享的意义

人们所造成的。人们真的很自私。地球给了我们很多很多美好的东西。给了我们生存的条件，给了我们活动的空间可人们回报给地球的又是什么呢?地球是我们人类的母亲啊!人类竟如此对待地球。

当人们这样肆无忌惮地损伤地球时，也遭受到了地球的报应。乱砍伐树木会导致昨天的森林变成今天的树林，今天的树林将会变成明天的沙漠，一次次水土流失的发生，让很多无辜的人们丧失了自己的生命;大量往湖里排放生活废水，使得用水资源短缺。昨天，人类喝的是自来水;今天，人类喝的是矿泉水;明天，人类喝的将是什么水?工厂胡乱排放废气，使空气受到污染，全球变暖。

亲爱的人们，醒醒吧!祖国的首都—北京已经被沙尘暴袭击着了。我们决不能在这样下去了，如果还不行动，那后果将无法想象。我们将不可能在地球上继续生存下去，我们人类将成为一个让自己“地球母亲”受伤，一个自己杀害自己的人。醒醒吧!地球已经受伤了，地球已经在哭泣，地球已经在流泪了，行动起来吧!让我们来挽救地球吧!

作为“地球母亲”的“儿女”让我们一起来保护我们的“母亲”吧!同时，也为了让我们能够更好的生活在地球上，为了我们能有一个更加美好、温馨的大家园，人类的明天如何?要看今天的人类了。

“只要人人都献出一点爱，世界将变成美好的人间”相信很多人都听过这首歌，是啊!我们的爱是无限的，只要人人都献出一点点，我们的明天将更美好。亲爱的人们，把你们无限的爱献出一点点吧!

我相信人们会把爱献给地球的，毕竟她是我们人类共同的“母亲”。亲爱的人们你们说对吧?相信地球的“儿女”—人类会用心回报“地球母亲”的，相信人们会做到，保护环境，人人有责任。

[高中环保作文：别让地球哭泣

科技在发展，人类在进步，从无知走向已知，从蒙昧走向文明。千百年的风雷激荡，千百年的高歌猛进，千百年的沧桑，千百年的辉煌。然而，千百年后，斗转星移，我们的家园又以何面目展现在我们面前呢?有谁愿意看到一个遍体鳞伤、欲哭无泪的地球呢?

近些年来，人类为了从大自然中谋取大量的财富，为了使自己的生活更加舒逸，自私地乱砍乱伐森林、大量开垦土地、排放工业垃圾……然而，这样做的后果呢?天空不再蔚蓝，溪流不再清澈，森林不再茂密，青山不再苍翠……

人类伤害了自然，自然必将惩罚人类!不信，请看：海啸、地震、沙尘暴肆虐全球，气候不断变暖，南极洲冰川渐渐融化，森林面积急剧减少，土地大量沙漠化……人类受到了空前的灾难!

回想以前的大自然，沐浴在自然的灵光里，铺开广阔的草原，撒下五彩的鲜花，“天似穹庐，笼盖四野”;山泉汩汩涌出，跌宕出生命的旋律;小河流水潺潺，诉说着自然的美丽……这是多么另人神往的境界啊!然而，这般美丽的大自然是如何变成了今天的惨状呢?环境的污染——这几个毁灭性的字眼害了地球、害了人类!人类，别再无休止地搜刮自然了!

是的，人类要发展，为了更好地生存所进行的资源以及能源的开发和利用是完全必要的，但是所有的开发和利用都应当从整个自然界，尤其是地球环境的生态系统加以全面、科学地考虑，然后再在保护自然环境、维护生态多样性的基础上，达到人与自然的协调。既保护了大自然又进行了发展，这才是两全之策啊!但是，就当前局势来看，即使人类不再破坏那些已存的自然资源、保护自然环境也是远远不够的。我们必须在已有的自然环境的基础上，通过人为的再建，使其恢复原本的自然风貌，从而保护生态系统中各种要素的均衡，这样才能达到保护环境的最终目的!

然而，要真正使保护环境得到落实，就必须从现在做起，进一步提高人们的思想认识，彻底甩掉传统观念，切实提高人们对保护自然资源的重视，全面认识自然资源的潜在价值，从而增强保护自然资源的自觉性，把保护自然作为自己的责任，把绿化环境作为自己的任务，从一点一滴做起，从身边做起，热爱自然，积极投身到绿化生态环境的行动中去。另外，要加强基础设施建设，兴修水利设施，在水土上大做文章，提高农业发展，改善生态环境。强化社会保护措施，加大保护生物资源的宣传，依靠法律，严厉打击破坏生态环境的不法行为，加大保护力度，从而营造全社会保护生物资源的良好氛围。

历史的教训是深刻的，人们付出的代价是惨重的，今天，肆虐的海啸、地震、沙尘暴已经给我们敲响了保护环境、拯救地球的警钟，相信人类已经觉醒，自然的歌声将会以快乐为音符谱写。相信未来，通过人们不懈的努力，人类的伊甸园将变得更加美好!

People travel by plane, by train, by ship, by bus. To me, the best way of traveling on a summer vacation is to go on foot.

My preference depends on the purpose of the travel. On a summer vacation I travel to refresh myself and to see the countryside. When I use my feet and walk on a grass covered path along a river or among the hills I feel detached from the noise of the city and closer to the nature. And when I travel on foot I get more freedom. I can plan my own schedule. I can choose my own route. I can stop where I like. And I can see things and people that I might miss if I travel on a train or on a bus. net

When faster and more convenient ways for travel are becoming available, I still favor using my own feet. I get much pleasure from it. People travel by plane, by train, by ship, by bus. To me, the best way of traveling on a summer vacation is to go on foot.

Yesterday my classmates and I went to on a picnic. According to our plan we would climb the West Mountain.

昨天我和我的同学去野餐。按计划要爬西山。

Early in the morning all of us gathered at the gate of our school, we started of at seven, soon it began to have a little rain. We kept on riding for an hour till we reached the foot of the mountain.

清晨，我们都聚集在学校门口，我们开始在七，很快就开始有一点雨。我们骑了一个小时，直到我们到达山脚下。

The little rain stopped then. We began to climb. Soon we reached the top of the mountain. How beautiful it was when we looked at the view from the top. We ran. sang, jump,

小雨停。我们开始爬山。我们很快就到达了山顶。它是那么美丽，当我们在山顶上看风景。我们跑了。唱歌，跳，

played chess, and had the pictures taken on the top of the mountain. and had lunch on the rocks. How happy we were!

下棋，还拍了照片在山顶。吃午餐的岩石上。我们是多么幸福!

After the lunch we went down the mountain. We got home at four, all of us almost gave out.

午饭后，我们下山了。我们四点到家，我们都筋疲力尽了。

我们班有八个环保小卫士，我们不能当一个有名无实的小卫士，所以我们决定今天上午去做一件跟保护环境有关的事情。

早晨，我7：00就起床了。当我穿好衣服时，我听见窗外传来“沙沙沙”的声音。我抬头向窗外望去，哇!天灰蒙蒙的正下着小雨。我一下子变得没主意了，心想：怎么办呢?到底是去还是不去，我犹豫了一下。不行，我不能说话不算话。记得爸爸说过：做事情要讲原则，不能做个言而无信的人。所以不管下多大的雨，我都要去。

于是我打着雨伞，拿着塑料袋和筷子去了我和同学们事前约定的地方，准备和同学们一起去捡路边的垃圾。我一个人一边打着伞，一边左看右看，等着同学们。时间就像河水一样一分一秒地流着，过了好半天都没有一个同学来。这时我的心里有些着急，又有些生气，感觉好像被欺骗了一样，最后我想干脆先回家打电话问问同学们到底来不来。

我又打着雨伞回到了家，刚一进门，电话就响了，原来是李昀珂妈妈打来的。她妈妈说叫我们等雨停了再去。哦!原来是因为下雨，同学们怕爸爸妈妈担心，避免生病。所以我也就不生气了。后来我又和李昀珂约好了，等雨停了我们老地方见。

快到9：00的时候雨真的停了，我迫不及待地拿着工具去了我们约定的地方。马上开始了我们今天的活动。我们一边走，一边捡，捡完路边的又捡草地上的，这时丁雨萱也加入了我们的队伍。我们三双明亮的眼睛认真地寻找着每一个角落里的垃圾。不到一会儿，我们的袋子就被烟头、果皮、纸屑胀得鼓鼓的。我们捡了一袋又一袋，我们的手弄脏了，可是当我们回头看见被我们捡得干干净净的马路和草坪时，我们开心地笑了。更让我们开心的是那一群大人们不时的夸赞，不断投来的赞许的目光，让我们笑得更甜了。

No one，regardless of race, religion or nationality, can deny that the world we live in is becoming increasingly intolerable because of the effects of global warming. According to many experts, even greater impacts are still on the way.

There are numerous causes for this problem. On one hand, human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming according to the theory. On the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem.

It is urgent that immediate and effective actions should be taken right away. First, more trees need to be planted to help improve and beautify the environment. Besides, stricter laws concerning global warming and irresponsible use of fuel resources have to be put into effect and achieved good results. In a word, there is a long way to go before we can take a comfortable world for granted again .

Many people are active in fighting against unfair treatment to colored people, women , animals and so on. Right now I am talking about fighting for respect to our environment.Though the environment doesnt have a mouth done to deprecate what humans have done to her, she retaliates through action. In the early years the Chinese cut down large quantities of trees, at the source of the yellow river, which led to the disappearance of big forests and terrible floods. As a result, the Huangtu plateau which once was once covered with grass and forests was turned into barrens that supported fewer plants. Another example was in several developed countries.

Because many chemical factories discharged poisonous gas without filtering it, poisonous cities were covered with so much poisonous gas that people were killed by the air they breathed in. What horrible scene!What we are suffering is only a small part of what the nature once suffered. If we dont take action to show respect to the environment, we will have to face an increasingly awful situation. Measures should be taken to protect the environment on which we are relying. First governments should forbid destroying vegetation, rivers and lakes, oceans, as and the atmosphere as well. Second voices should be made to announce the public of the importance of protecting the environment. Third enterprises should pay special attention to the effect they have on the environment and work out solutions for the problems. Only by changing the way we treat the environment can along we get along well with it.

Only by saving the environment can we save ourselves.

Friend plays important role in our lives. Everyone needs his or her own

friends. Some people make friends easily but some do not. And “friend” means

differently to people. Some people think friends should stay together all the

time, but some others think that share and support is the real meaning of

friend. From my point of view, friend is the person who will always be with you

no matter what happens. It’s the person who can share your happiness as well as

sorrows.

The happiest memory in my childhood was making snowman with my friends. As

I was a little boy, I always went out with my friends to make snowmen and play

with snow when it snowed heavily. We divided ourselves into several groups, two

or three people in each group. Then, we began to make our own snowman. We used

buttons to be snowmans eyes and carrots for its nose. After making our snowman,

we compared ours with others’ to decide whose snowman is the best. Sometimes, we

wrapped our scarfs around snowmen or put our caps on their head, so as to make

our snowman more beautiful. The last time I making a snowman was when I was in

university. But it snowed rarely these years. Thus, making snowman has become

the long-lost fun for me. How I hope it would be snowy this winter!

Christmas Day is very popular around the world, when that day comes, we can

see the Christmas products sell everywhere, though Christmas Day is not

originating from China, in our country, more and more people spend that day. A

foreigner pointed out that Christmas meant to be grateful for them, while for

Chinese people, it was just a day for celebrating. To me, Christmas indeed means

a day to have fun.

When I was small, I did not have the concept of Christmas, because in my

mind, I only knew Chinese traditional festivals, I liked Spring Festival best, I

could get a lot of money from parents. When I went to high school, all of my

friends would talk about Christmas Day when the day was near, so I started to

know it. Almost every young people like Christmas, but if you ask them what the

meaning of the day, less of them can answer.

The meaning of Christmas Day is to remind people of Jesus’s birth, it is so

important for the western people, but for me, I only want to have fun, everyone

is celebrating it, so I join them, being happy, that’s enough for me.

the third and fourth days are for the sons-in-laws to pay respect to their parents-in-law.

the fifth day is called po woo. on that day people stay home to welcome the god of wealth. no one visits families and friends on the fifth day because it will bring both parties bad luck.

Hello, everyone. I’m am a student in No.1 Middle School. I’m very proud that I have been chosen to speak to you all today.How to protect/save our environment/world?

The environmental pollution is worse and worse /more and more seriously today. Water is polluted ,we have no clean water to drink Many trees are cutting down, some animals is getting less and less.Some factories is poring dirty air in the sky , the population is increasing faster and faster ,resources is getting less and less…etc. Not only does it affect our lives and health, it also has a great affection in the future.

The first fact I worry about is noise pollution. People can"t sleep well if there is too much noise. That"s why so many people prefer to live in the countryside rather than live in the noisy city. I suggest all the factories and cars shouldn"t make terrible noises. If they make terrible noise that isn"t allowed, they will be fined, and we can also produce the cars which can"t make terrible noise.

The other pollution is rubbish pollution. If everyone makes so much rubbish, one day we may live in a world filled with rubbish. Some people throw the waste paper about. I suggest rubbish should be put into different kinds of dustbins or paper bags.

Once Chairman Mao said one is never too old to learn, his famous words inspire people to keep learning all their lives. Since we are small, we study at school, then we have to learn until we are at college, after graduate from college, we finish our education in the school.

Then the new stage comes, we start to work, making money, learning knowledge seems unnecessary to us.

This is totally wrong, we learn all the time, even we are out of school, we have lessons from life.

Life is a big topic, we have to learn it all the time. We have to deal with trouble, learning to make friends and accept fail.

All these things we will not learn at school, we have to learn by ourselves, we are students and teachers. If you think you finish learning after school, you are narrow minded.

毛主席曾经说过“一个人要活到老学到老”，他的著名话语激励着人们终身学习。

当我们还小的时候，我们在学校学习，然后直到大学前，我们都要学习，大学毕业后，我们完成了在学校的学习。然后新的阶段到来，我们开始工作，挣钱，学习知识似乎不必要了。

这是完全错误的，我们一直学习，即使不在学校，我们学习生活。生活是一个大主题，我们不得不一直学习。我们要处理麻烦，学着交朋友和接受失败。所有的这些东西我们都不会在学校学到，我们必须自己学习，即是学生也是老师。如果你觉得你出了学校后就完成了学习，你的思想就很狭隘了。
