Because of the high developing speed of the world, pressure has become a

serious problem in nowadays. As our students, we also have to face with much

pressure, such as the study pressure, exam pressure,relationship pressure and so

on. But how can we cope with pressure? This is the most important.

Firstly, we should face the pressure appropriately. Pressure is inevitable

in our daily life, so we cant be afraid of them and try our best to cope with

them. Secondly, tell our pressure to others. Talking is a very effective way to

ease pressure, and during the talking, we may get some suggestions and

solutions. Finally, trust ourselves. We should believe ourselves that we can

deal with any troubles by ourselves or by others help.

Today is the National Eyes Caring Day,so I remind everybody to treasure your eys.Now let me introduce something should be remembered to treasure our eyes especially to the stdents.

First of all,its important to keep the standard sitting position while you are reading and studying which means that you cant put your eyes to close to the books or notebooks.Secondly,you should keep on doing eye exercises during the ten-minute break carefully.Thirdly,try to look far into the distance during the break,too.Besides,you should remember that if there is something wrong with your eyes,go to see the doctor in time.I believe that if you do as what I say,you can keep on owning good eyesight.

Trees are important resources. They provide us with wood, which is not only an important building material, but also indispensable in making paper, furniture, matches and many other useful things. Without tress, we would perhaps still be living in caves, and our life would be very miserable.

Trees also do good to our environment. They not only make our world greener and more beautiful but also produce oxygen which makes the air we breathe fresher and better for our health. What’s more, trees help maintain ecological balance, which is very important to our survival.

Fortunately, trees, unlike other resources, can be “reproduced”. While coal and oil can be burnt up and exhausted, trees will never be used up because we can always plant new ones. And when we plant trees, we know that we are helping make our world richer, pleasanter, and more beautiful to live in. So let’s plant more trees.

Green represents all plants, green represents the appearance of a city.

Maybe now is not the lack of green around us, but after 10 years, 20 years later, or even 100 years later the world is what its like to be? We never know what, but in the future if one day the world is the day we didnt know to cherish? So, we should ponder, to really go to contribute to our home, not on the mouth say dont act, have a flyer so simple, that is the worlds people to work together to do!

Maybe I say very serious but thats the truth. Summer vacation the streets every community in the garbage classification, also for all kinds of activities. In the supervision and inspection for a long time under the guidance of most residents are consciously throw rubbish classification. But not for long, for a period of time you dont consciously, every household can not really clear of each garbage, a black bag thrown who will know whether it is dry or wet garbage. This only shows that we are not consciously, just let it go.

Recycling garbage classification, plant greening, etc. Its all about trying to a green home, we should actively participate in, to mobilize.

Environmental protection is inseparable from the us, only green city will be more healthy and beautiful. Environmental protection bags refused the "white pollution", the disappearance of the disposable chopsticks refused to cut down trees these examples abound. World expo and exhibition of various resources reuse of environmental protection concept to us, our life and environment have been together, I think the world expo is the environmental protection pioneer, really tells us that environmental protection is the first major step of the world.

Green is around you, hope still can appreciate slowly with handguns?

Environmental protection is in the life, is to some more or less?

To build green homes, together to study environmental protection pioneer, believe that 10 years after 20 years, 100 years later the world is still so beautiful, dont want to disaster.

绿色代表了一切植物，环保代表了一个城市的面貌。

也许现在我们身边不缺少绿色，但10年后，20年后，甚至100年后世界又会是什么样子呢?我们无从猜测，但未来如果有一天世界毁灭了难道那一天我们才知道要珍惜吗?所以，我们要深思了，要真正去为我们的家园做贡献，并不是口上说说不行动，发发宣传单这么简单，这是全球人要共同努力做到的事!

也许我说得很严重但事实如此。暑假里各街道各社区都在进行垃圾分类，还进行各种活动。在长时间监督人员检查指导下大部分居民都自觉扔垃圾时分类。但好景不长，又过了一段时间大家就不自觉了，每家每户不可能真的每样垃圾都清楚，一个黑袋子一扔谁会知道里面到底是干还是湿垃圾。这种情况只说明我们不自觉，只是别人让这么做就去做。

垃圾分类，种植绿化，回收资源等等这都是为了一个绿色家园在努力，我们要积极主动参与，动员起来。

环保也离不开我们，只有环保的城市才会更加健康美好。环保袋拒绝了“白色污染”，一次性筷子的消失拒绝了砍伐树木这些例子数不胜数。世博会上又向我们展各种资源再利用的环保概念，我们的生活与环保已联系在一起，我想世博会就是环保先锋，真正告诉我们环保是世界迈出得第一大步。

绿色就是身边，是希望一晃而过还是可以慢慢欣赏?

环保就是在生活中，是希望多一些还是少一些?

去一同建造绿色家园，去向环保先锋学习，相信10年后20年后，100年后世界依然这样美好，不希望灾难降临。

My fiat is made up of eight rooms：one hall，one bathroom，one kitchen，one dining room，one living room， two bedrooms and one toilet。The hall faces the front door。 When you come into my flat，you will first see the hall。The bathroom is on the right，and the toilet is on the left。In front of you，there are two doors。The left one leads to one of the bedrooms，and the right one leads to the living room。When you come into the living room， you will see two doors again。The left one leads to another bedroom，and the right one to the kitchen。The kitchen goes straight to the dining room。Besides，there is also a balcony next to the living room and one of the bedrooms。

Nowdays, with the rapid development of the road, cars have been playing an increasingly important role in our day-to-day life. It has brought a lot of benefits but has created some serious problems as well. Traffic safety as the most importent one, is closely related to everybodys business.

This phenomenon exists for a number of reasons . Some of the accidents are due to mechanical problems. As the vehicles in the road become common, the function of vehicles has improved and the speed is getting faster. However, most of them are the results of careless and reckless driving, which could not be avoided. A lot of people disregard traffic signals and rules. They drive regardless of speed limits, run through red lights, drive in the wrong direction, talk and laugh while driving, and turn at will without giving signals. They even dont slow down while approaching crossroads. So many people violate traffic regulations that we cannot put too much emphasis on the importance of traffic safety. Meanwhile, we can not ignore the fact that there are many problems existing in the design. They are all important reasons accounting for this phenomenon.

Some effective measures must be taken to slove this problem. The major cause for traffic accidents is people’s lack of safety awareness. Completing a safety driving education course is a very important way to reduce the number of traffic accidents. The key point for this issue is people’s awareness towards safety. It is a long-term goal rather than a single course for safety driving. The best way to solve the troubles is that we all abey the traffic rules. First, we cant get through red light and must observe traffic order. Secondly, tell our relatives not drive after drinking. Then, we should be care about road damage and inform relevant departments to solve the problems early. Finally, an active part in social activities, protect our order society! Another measure is improving the traffic condition by add traffic signal and other traffic safety facilities。Only when everybody takes traffic safety as their own business, can we achive safe driving and walking on road.

Last but not least, I hope we can have a good futere , and I believe we can do it！

说起感恩父母，大家肯定会说父母是生养我的人，当然要感恩。在这里首先我们要感谢他们让我们降生到了这个美丽的世界上。没有他们就没有我们，没有他们就没有我们的今天，没有他们就没有我们现在的好成绩。

父母是我们在人生道路的第一任老师，从我们开始学说话、走路，一直到长大成人，每一次成功，甚至是每一次失败，父母都会牢记在心头，陪在你身边，给予你默默的支持，耐心的开导，让我们很快学会了如何做一个对社会有用的人。所以我们有了这样的父母，才会有快乐的今天。

父母也是最最疼爱我们的人。哪怕是身上划破一点轻伤，他们都会很自责，心里总想为什么没有看好自己的孩子。如果你得了病，他们肯定急得吃不上饭、睡不着觉，甚至会哭上一会儿。记得有一次，我发高烧，妈妈背着我去医院，从她那焦急的神态中我深深的体会到父母对我是发自内心的爱。父母像照顾一个个小天使一样照顾着我们，让我们长成了一个健康活泼的大孩子。他们为我们付出，为我们做一切从来不要求回报。

同学们，让我们学会感恩吧!用一颗感恩的心去对待自己的父母，用一颗心真诚的心与父母交流，不要认为父母是理所当然帮我们做任何事的，他们把我们带到这个美丽的世界上，已经是足够的伟大，且将我们拉扯大，还不求回报，默默地为我们付出，感恩吧!感恩父母们给予我们的一切!

再此，我也祝愿天下的说有父母安康!快乐!

或许你会注意到，现在地球妈妈总是遭受到各种各样的伤害。河流好像没有以前那么清澈了，他们原本干净的衣裳被渐渐染黑;空气远不比昔日清新宜人，天空灰蒙蒙一片，再也难以看到那般蔚蓝，璀璨夜空已经成为了过去;鸟儿更是踪迹罕见……人类为了一己之私，一次又一次无情地伤害着地球妈妈，致使她原本美丽的脸庞已经变得千疮百孔。其实，只要我们每一个人都懂得爱护环境，成为地球卫士的话，地球哈哈哈病就会慢慢痊愈!

空气是我们赖以生存的元素之一，但现在空气变污浊了。随着生活水平的提高，小汽车越来越多，小汽车屁股冒着的废气却严重污染环境。因此，我们平时要少开小汽车，多乘坐公交车或地铁等公共交通工具，这样就能大大减少废气的产生。另外，我们也要注重绿化，多栽花植树，净化空气，使我们的城市成为真正的“花城”，处处清新怡人。

水是我们生命中不可缺少的，但它也逃不过被污染的厄运。为了自己的利益，许多工厂把废水直接排入河流中，原本清澈的河水瞬间变色。他们是否知道，如今地球上的淡水资源已经寥寥无几了，决不能再污染浪费地球上的每一滴水，不然最后一滴水将会是我们所流下的眼泪。节约用水应该从日常生活中做起，尽量循环利用水资源，比如用洗米水来浇花，用拖地水来冲厕所……

对于保护环境，做好垃圾分类也能起到很大作用。在大街上垃圾随处可见，那是因为有些人为了方便自己，垃圾随手一扔，没有要把垃圾放进垃圾桶里的自觉性，更别提垃圾分类了。其实，只要人人在处理垃圾的时候树立正确放置垃圾的意识，做好垃圾分类，就是解决环境污染这个大难题最行之有效的办法之一。

为了使空气更新鲜，河水更清澈，天空更湛蓝……我们一起行动起来，齐做“绿天使”，从自己做起，从身边小事做起，保护好自然环境，让地球妈妈恢复以前的美好、和谐吧!

In the past few decades, our Earth has changed a lot, but to the bad direction. Among these changes, the air pollutions resulting from a huge number of automobiles and coal-burning is almost the severest. The severe air pollution alarms humans of the heavy load we have exerted on Earth by our insatiable production and usage of automobiles. However, with the deepening of urbanization, more cars are needed, which will make the air pollution worse. Therefore, the following actions should be taken. First, we should apply the most cutting-edge technologies in order to adopt new forms of energy as substitutes for fossil fuels. Second, try hard to develop possible transportation means, which are enviromental friendly. So that the citizens can reduce the dependence on cars. In short, our humans should take responsibilities for the air pollution and have to find ways to solve this problem.

在过去的几十年中，我们的地球发生了很大变化，但是是往坏的方向。在这些变化中，大量汽车和煤燃烧产生的空气污染是最为严重的。严重的空气污染警告人类，我们无休止的的生产和使用汽车给我们的地球带来了沉重的负荷。然而，随着城市化的加深，汽车的需求量也越大，这会导致空气污染更严重。因此，我们应该采取以下行动。首先，我们应该运用最尖端的技术，以新型能源作为化石燃料的替代品。其次，努力寻找可能的环境友好型交通方式。这样城市居民就可以减少对汽车的依赖。简而言之，人类应该承担空气污染的责任，寻找解决这一问题的方法。

导语：无规矩不成方圆，每个学校都有自己的校规，你们学校的校规是什么呢?下面是yuwenmi小编为大家整理的学校校规英语作文，欢迎阅读与借鉴，谢谢!

Welcome to our school, Mary. Here are some of our school rules. Let me tell you: We cant arrive late for class. We cant talk loudly in class. We have to be quiet in class, and we have to keep our class clean. When we meet the teachers on the way, we must greet them. We cant eat or drink in the classroom. But we can eat outside. We cant listen to music or play games in class, either. We cant pick flowers or climb trees.

【参考译文】

欢迎来到我们学校，玛丽。以下是我们学校的一些规则。让我告诉你：我们上课不能迟到。我们不能在课堂上大声说话。在课堂上我们必须保持安静，我们必须保持课堂清洁。当我们在路上遇到老师时，我们必须问候他们。我们不能在教室里吃或喝。但我们可以吃外面。我们不能在课堂上听音乐或玩游戏。我们不能摘花或爬树。

Everybody needs themotivationto move on, so no matter what kind of difficulties they meet, they can see the hope and stick to the targets. I have set up small targets for myself, so I can make progress step by step. For example, when I jog on the playground for 800 meters, I will finish every 100 meters as the small target, so I can finish my task easily. If I think about 800 meters at first, I will lose my motivation and give up quickly. Motivation is like the light in the dark, leading us to reach our destination. Find our aim and set up the small plans. We can make it anyway.

每个人都需要前进的动力，这样无论他们遇到什么样的困难，都可以看到希望，并坚持以达到目标。我为自己设立了小目标，这样就可以一步一步地取得进步。比如当我在操场上跑800米时，我会把每次的100米当做小目标，这样我就可以很轻易地完成我的任务。如果我一开始就想着800米，就会失去动力，迅速放弃。动力就像是黑暗中的光，引导着我们到达目的地。找到我们的目标和设立小的计划，就总能成功。

清晨，我迎着太阳的第一缕霞光去上学，放眼望去，只见湛蓝的天空上飘着几朵白云，绿色的.树木挺立在道路的两旁，空气是非常清新的，大地生机盎然……

当地球母亲把这一切都无私的奉献给我们的时候，她自己却在遭受着残痛的摧残：环境恶化，空气污染，森林滥伐，物种灭绝……瞧！烟囱里又冒出一缕缕黑烟，小鸟们都被熏走了；看！往日清澈见底的小河变得又黑又臭，鱼儿都无法生存下去了；在“嘎吱、嘎吱”的电锯声中，一根根苍翠挺拔的大树倒下去了。因为人们的滥砍滥伐，使得水土流失，造成了严重的大水灾。其实地球妈妈所拥有的自然资源是有限的。这一系列的环境问题，正使人类面临可怕的挑战。

地球仅有一个，我们应该立即行动起来，像珍惜自己的生命一样保护地球，为我们美丽的家园献上一份自己的爱心！

我们每天都要注意节约用纸。纸是用树木来造的，每节约5000张纸就可以少砍一棵树。大树能净化环境，使人类不断地获得新鲜空气，它还可以挡住风沙，可以防止水土流失……我们每人每天节约一张纸，这样就可以保留下一片大森林。有了森林，也便有了绿色；有了绿色，便有了怒放的花朵；有了绿色，便有了健康的生命、美丽的家园。

我们平时还要注意节水。在我国600多个城市中有半数以上缺水，其中108个城市严重缺水。当想到其它地方还有那么多人每天没有水喝的时候，我们又怎能再忍心去浪费一滴水呢？平时要多收集节水小窍门，比如，淘米水还可用来洗菜，清洗衣物的水可擦门窗及家具等。

节约一张纸、节约一滴水……我们做的虽然是小事，但却为环保做了奉献。我希望同学们从现在开始，都来做一个环保小卫士。环境是人类生存的基础，保护环境是我们每个人的责任。

同学们，再小的力量也是一种支持！让我们从自身做起，从点点滴滴做起，为我们的地球家园缔造一个美好的明天吧！

Our environment is very important for our lives 。 We need the fresh air， the clean water and so on 。 In the past， there were many trees around us ，the air was fresh and the river was clean。But now，people cut down many trees。 Air pollution and water polloution are very serious 。 The environment around us bees very terrible 。 We should protect our environment。 First， we should plant many trees to keep water。 Second ， we can ride a bike or walk to the school and work。。 Third ， we shouldn’t throw the dirty water into the river 。 Fourth， we shouldn’t use the plastic bags。 Finally， we can ask more people to join us。

Throughout history man has changed his physical environment in order to improve his way of life. With the tools of technology he has altered many physical features of the earth. He has transformed woodlands and prairies into farms and made lakes and reservoirs out of rivers for irrigation purposes or hydroelectric power. Man has also modified the face of the earth by draining marshes and cutting through mountains to build roads and railways.

However, mans changes to the physical environment have not always had beneficial results. Today, pollution of the air and water is an increasing danger to the health of the planet. Each day thousands of tons of gases come out of the exhausts of motor vehicles. Smoke from factories pollutes the air of industrialized areas and the surrounding areas of the countryside. The pollution of water is equally harmful. The whole ecological balance of the sea is being changed and industrial wastes have already made many rivers lifeless.

Now environmental protection is more pressing than ever before. As we know, massive destruction of environment has brought about negative effects and even poses a great threat to mans existence. Indifference to these problems will mean committing suicide. Therefore, effective measures should be taken and laws passed to conserve environment. Otherwise, man is certain to suffer from the serious consequences caused by this lack of care for his living surroundings

历史上的人改变了他的物理环境,以改善自己的生活方式。借助技术工具改变了地球的许多自然特征。他将林地和草原改造成为农田,使江河变成湖泊和水库,用于灌溉或用于水力发电。男人也修改了地球表面由高山沼泽和切断山区修建公路和铁路。

然而,人的物理环境的变化并不总是有有益的结果。今天,空气和水的污染是越来越危害地球的健康。每天成千上万吨的机动车辆的排气管排出的气体排放出来。工厂释放的烟雾污染了空气工业化地区和周边地区的农村。水的污染也同样有害。海洋的整个生态平衡正在改变,工业废物已经使许多河流毫无生气。

现在,环境保护比以往任何时候都更为紧迫。正如我们所知,环境的巨大破坏已带来负面影响,甚至对人类造成巨大威胁的存在。对这些问题漠不关心将意味着自杀。因此,应采取有效措施并通过法律来保护环境。不然的话,人类势必遭受缺乏所造成的严重后果关心生存环境

After 5.12 earthquake struck sichuan province since 2008, we, I was so frightened by an earthquake, I felt the earthquake many houses will be apart, can let many people lost their lives, is one of the worlds most terrible disaster. Today I saw "China childrens encyclopedia, really know anything about earthquake.

It turns out that the earthquake happened all of a sudden the vibration phenomenon, like the wind, rain, is a kind of common natural phenomena. Vibrations in the earth, in fact, very frequently, probably every 30 seconds there will be time, but most of them are very ease, people did not feel. We can feel the earthquake is due to the relative movement between earths tectonic plates, rock is squeezed, produce a huge amount of energy to make rock failure in an instant, or make originally the already existing fracture activity, suddenly release a large amount of energy, and some of the energy to the earths surface, make the earth trembling violently, causing strong earthquake. Started happening earthquake site is called the source, the source above the ground is called the epicenter, the ground of the devastating earthquake is the most strong place is called the magistoseismic area, while the magistoseismic area often is the place where the epicenter. When the earthquake occurred, the source of shock wave in the earths crust to all directions called seismic waves. Seismic waves hit the ground, the result will be a disaster.

We Chinese people are very smart, as early as the eastern han dynasty, there is a man named zhang heng scientists invented to measure the earthquake Hou Feng seismograph, and our modern scientists are generally measured the spread of seismic wave speed with the help of a seismograph, the place and time of the earthquake.

Know the earthquake knowledge, learning even before the earthquake early warning and self protection method, I think, to know that knowledge is very useful for our own.

自从2008年我们四川发生5.12大地震之后，我就特别害怕地震，我觉得地震会震垮很多房屋，会让许多人失去生命，是世界上最可怕的灾难。今天我看了《中国少年儿童百科全书》后，才真正知道地震是怎么回事。

原来，地震是突然间发生的大地震动现象，就像刮风、下雨一样，是一种很普遍的自然现象。地球上的震动实际上非常频繁，大概每30秒种就会有一次，但大多数都非常缓和，人们都没有感觉。我们能感觉到的地震是由于地球板块之间产生相对运动，岩石层受到严重挤压，产生巨大的能量使岩石在瞬间发生断裂，或者使原来已经存在的断裂突然活动，释放出大量能量，而其中一部分能量传到地球表面，使大地剧烈地颤动，从而引起强烈地震。地震开始发生的地点称为震源，震源上方的地面称为震中，破坏性地震的地面最烈处称为极震区，而极震区往往就是震中所在的地方。地震发生时，震源发出的在地壳中传向四面八方的冲击波称为地震波。地震波冲击到地面，就会引发灾难。

我们中国人非常聪明，早在东汉时期，就有一位叫张衡的科学家发明了用来观测地震的侯风地动仪，而我们现代的科学家也一般都借助地震仪来测量地震波的传播速度，判断地震发生的地点和时间。

知道了地震知识以后，还要学习地震发生前的提前预警和自我保护方法，我想，了解到这些知识对我们自己是非常有用的。

With the explosion of population in the world, more and more poisonous waste is produced. As a resuit, a lot of rivers and lakes are polluted. In some areas, the air also becomes dirty and harmful. Consequently, animals and plants are endangered. And peopies health is greatly affected.

Fortunately, more and more people have realized the serious situation. Many countries have passed laws to prevent the environment from being further polluted. People are working hard to find ways to keep the earth clean: they treat waste gases, protect water sources and purify waste water. Definitely, controlling the increase of population is one of the most efficient ways.

However, in future more efforts will be needed to win the battle against pollution, The laws controlling pollution must be strictly enforced, And above all, attention should be paid to the education of the people so that everyone will show his concern about environmental protection.

Low-carbon life is good for everyone. To help with the environment, I always walk or ride a bike to school instead of taking a car. Besides, I will try to use things that can be recycled and I never forget to turn off the lights when I leave the classroom. I think it’s my duty to live a low-carbon life. And even the simplest activities can make a real difference to the environment. So I suggest we should reuse books as long as possible. And we’d better not spend much money on expensive clothes. If everyone does something for the environment, I believe the earth will be a better place.
