[保护环境的英语小作文

There are still many environmental problems in recent years.One of the most serious problems is the serious pollution of air, water and soil.The polluted air is very damaging to peoples health.Polluted water causes diseases and deaths.More importantly, the vegetation has been greatly reduced, with the rapid growth of modern cities.

In order to protect the environment, many governments have done a lot of work.Introduced legislation to control air pollution, protect forest resources and Marine resources, and stop any environmental pollution.Governments, therefore, are playing the most important role of environmental protection today.

I think the government must take more concrete measures to protect the environment.First, the government should make the people fully aware of the importance of environmental protection through education.Second, more efforts should be made to implement policies on population planning, because more people mean more people mean more pollution.Finally, those who intentionally destroy who should be severely punished.We should let them know that destroying the environment means destroying humanity itself.

【翻译】

仍然有很多环保问题在近几年。最严重的问题之一是空气，水和土壤的严重污染。污染的空气严重损害人们的健康。污染的水引起的疾病和死亡。更重要的是，植被已大大减少，随着现代城市的快速增长。

为了保护环境，许多国家的政府都做了很多工作。介绍了立法措施控制空气污染，保护森林资源和海洋资源，制止任何环境污染。因此，各国政府正在发挥环保今天最重要的作用。

我认为，为了保护环境，政府必须采取更具体的措施。首先，政府应该让人民充分认识到环境保护的重要性，通过教育。第二，更应努力把人口规划实施的政策，因为更多的人意味着更多的人意味着更多的污染。最后，那些故意破坏谁应该受到严厉惩罚的环境。我们应该让他们知道，破坏环境就是毁灭人类自己。

时间过得真快，一眨眼，快乐的寒假生活即将结束，回顾整个寒假，我觉得我过得充实而又快乐。

刚放寒假不久，我们全家来了一次大扫除，那天一大早，我们就开始分工：爸爸擦柜子，妈妈擦地板，我擦玻璃。

说行动就行动，我先拿报纸将玻璃仔细地擦了一遍，然后找来了“好帮手”“一擦净”。我把里面的两块海棉弄湿，将“一擦净”的一半放在里面，另一半放在外面，紧贴着玻璃，“啪”吸胶吸住了，我用线牵住外面的一半，然后有顺序地一上一下移动。我一口气擦了

五扇窗，擦过的窗户干净极了，甚至让爸爸看外面时，撞起了一个包。

为了奖励我，爸爸答应去钓鱼的时候也带上我，但前提是我不能发出声音。我连连答应。几天后，爸爸带我来到野外的一个大池塘，拿出钓鱼竿，帮我放上蚯蚓，我选了一个地方，把它甩下去，然后静静地等着鱼上钩。等了半天，一点动静也没有，我几乎想扔下钓鱼竿去玩了，可一看爸爸的桶里已经有好几条鱼了，又不甘心输给他，就只好拿着鱼竿干等，眼睛直勾勾的盯着浮标，忽然浮标微微颤动了一下，我揉揉眼睛，它又动了一下，我确信鱼上钩，就一把将鱼竿提起，哈哈，一条大鱼，我朝爸爸昂了昂头，爸爸也用惊讶的目光看着我，我真是太开心了!

有了一个好的开头，我自信了，不再轻易想放弃了。于是，幸运女神降临到了我头上，大鱼小鱼都来吃鱼饵，我来了一次大丰收。回到家，爸爸妈妈都不得不向我竖起大拇指，我也好佩服自己。

对了，你的寒假过得怎么样，是不是也像我一样充实而又快乐呢?

Some people believe that economic development should never be at the cost of the environment.They think the present serious environmental problems are largely caused by rapid?economic development.For example,land resources are shrinking because of the industrial development and the expansion of cities.Deserts are spreading because of over grazing,poor fanning,tree cutting,and strip mining.Our air and water supplies are being polluted by poisonous gassesand waste products.It is important,therefore,that we should take another look at the way in which our industries and cities are developing.

However,other people think it unnecessary to consider environmental problems now and our first priority should always be given to economic development.They believe that environmental problems are inevitable and unavoidable in the process of economic development.They are only the by products of economic development,which can be dealt with later when we have the time and money.

I think the second idea is completelywrong.Our ultimate aim in economic development is to provide a comfortable and happy life for our people.What is the point of economic development if we achieve it at the cost of our environment?There has been much evidence to prove that a balance between the two helps more rapid and continuous development.

Today, my brother went to school in Jinan and my father brought me up. Dad wanted me to feel the life of the University. We came to Shandong Normal University, and that was the fathers alma mater.

I want to grow up quickly and get into the dream college life earlier.

Today I am very glad here to share my opinionsabout the protection of environment.

With the development ofscience and technology ,different kinds of pollution has been produced andcaused global concern recently.

As we know, people have beenliving on the earth for thousands of years, human activity damaged natural environment, such as excessive abuse of natural resources ,the sewage dischargedfrom factories ,the animal slaughter ,kinds of chemical fertilizers andgreen-house effect. All that is mentioned above has a bad impact on the eco-system .Now, many animals aredying out. We are suffering from unhealthy food and water, we are faced withharmful rays and global warming. It was ourselves who had made a series oftroubles. As you can see, we are the final victim.

Above all, if we human beings cannot recognize theseserious problems and try our best to solve them soon, we would finally lose theenvironment suitable for us to live. So, it is our duty to protect theenvironment ,but what should we do to protect it?

In my opinion, the first and important thing is tounite all forces ,that is to say---gather all hearts together. Next we shouldprotect and plant more trees, which can dispose of the dust in the air. As forfamilies, it is effective to ride bicycles rather than drive cars. Don’t litteranywhere as you like. In addition, sorting and recycling the rubbish also playan essential role in the protection of our earth. We’d better call on everyone aroundus to lead a low-carbon life, as it may make a difference to the environment.

Thus, it’s high time that we did something to improveour surroundings. Everybody should raise the awareness to protect our motherearth. Let’s appeal to more people to join us.

All in all ,there’s no doubt that keeping the balanceof human and nature ,we will benefit a lot.

Thank you for listening！

My school life in primary school is wonderful! I have a lot of friends. They are friendly to me.We study together play together and talk together.My teachers are very patient .They teach me a lot and help me with many problems. The school life is unforgettable

You should spend about 40 minutes on this task.Write about the following topic:

The earth is being filled with waste material such as plastic bags and other rubbish. Is this really happening? What are some solutions to this problem?

Gives reasons for your answer and include any relevant examples from your own knowledge or experience.Write at least 250 words.

model answer:

Over the past few decades, the increasing amount of industrial wastes and household garbage has become a major problem in many countries. People have questioned what caused this problem and what can be done to improve the situation. In my opinion, two of the most critical causes of this waste material problem are the increased consumption and a shortage of space for landfill.

To begin with, modern lifestyle has contributed greatly to the increasing amount of waste and garbage we produce everyday. In other words, we have turned into a materialistic and mass-consumption society where we use more and throw away more than ever before. Moreover, countries are running out of space to store garbage and waste material. In fact, securing land for waste disposal raises controversies in many countries.

To solve this intractable problem, every citizen needs to participate in producing less garbage. For example, we can bring our own personal shopping bags instead of using plastic bags provided by stores and shops. Besides, the government can enforce stricter laws on companies to use biodegradable packaging or use recycled material. Indeed, this alone can eliminate much of the waste which is sent to at land fills. Companies can also contribute by developing new raw material which is recyclable and will ultimately lead to less garbage. One good example of this is that tire companies develop new tires for cars which are not made of rubber but of new biodegradable material.

As discussed above, individuals, business and the government can share the responsibility to reduce the amount of waste material and to save the earth. I hope that in the future our offspring will be better off with the well-preserved environment.

环境保护雅思英语作文

Environmental hazards are often too great for particular countries or individuals to tackle. We have arrived at a point in time where the only way to lessen environmental problems is at an international level.

Environmental problems have reached such proportions that people feel international organizations must be set up to intervene in world affairs to resolve these problems. Whether this will resolve the problem is very unlikely as international organizations are just an extension of human behavior. That is, if human conflicts cannot be resolved at home, then they are unlikely to be resolved at the international level. Nevertheless, international organizations do attract attention to the growing problem of aims of the international community to resolve the issue of environmental pollution and support their cause, I do not believe it is the best or only way to protect the environment; in fact, it is only a small part of what is needed in a global initiative.

All world problems, whether it is environmental pollution, war, energy insufficiency, or famine, arise from the abusive behavior of all individuals. Therefore, the solution to all these problems is the need for a collective consciousness. What is meant by this is that each individual must be aware of the impact he or she has on the world and their unique part to play in this world. After all, if one is happy with his life, he will surely not endeavor to harm the environment or anyone else. His behavior will be that of a responsible individual.

What is needed, therefore, is education. Education is the key to all problems and it starts from pregnancy all the way to adulthood and beyond. Furthermore, education means that children all over the world should be allowed to go to schools with good teachers and where teaching materials and methods can be adapted to each individual. Education means raising children to be responsible individuals.

This may sound like utopia, but it is not: if a country had important problems in its educational system, then it should realize that it is contributing to the worlds problems. These are perhaps long term solutions, but they are more realistic solutions than setting up yet another international organization.

我们同住地球村，就应该好好保护地球。现在整个世界都在倡导低碳生活，以此来更有效的保护我们的环境，保护大自然。那么什么是低碳生活呢？低碳生活是指生活作息时所消耗的能源的减少，从而减低碳消耗，尤其是二氧化碳的减少。也就是说，低碳生活就是更低能量、更低消耗的生活方式，还原其淳朴的进行人与自然的交流。

低碳生活是一种非常环保、文明的生活方式。节电、节水、节碳、节油、节气，从一点一滴的小事做起，我们的地球需要我们共同来爱护。我们要从身边的小事做起，珍惜资源，降低能耗。我的低碳小窍门是：大自然是我们改不了的，但我们能稍稍改改自己的习惯。

我在用电脑上网的时候，如果长时间不用，就关掉电脑拔下插头。每天看电视的时间不超过两小时，看电视时声音不能太大。天气热的时候，我就不一定非要呆在家里，我可以出去游泳，这样既节约了用电又锻炼了身体，并且还很凉爽。当我在家必须使用空调时，空调的温度不易过高，当我爸爸把温度调到很低时，我就主动把温度调到26－27度，并告诉他这样可以节约用电。出去吃饭时，我不用一次性筷子，我和妈妈总是自己带筷子和水杯。上超市购物时，我总是不忘带环保购物袋。平时我也勤动手动脑,当我看到我们家有很多废弃的盒子，比如牛奶盒，我在盒顶稍加裁剪，就能放在厨房盛东西，有的包装盒很漂亮，我就把盒子做成实用的纸巾盒或其它的储物盒。这样就可以轻松做到废物利用。我和爸爸妈妈出行时一般是步行、骑自行车或乘公交车。在学习中我尽可能节约用纸，少用打印纸，用过的打印纸反面再打印一次或当演草纸……

你看这些看似不经意的小事，但都是在为“减碳”做贡献。只要我们去行动，从一点一滴的小事做起，就可以接近低碳生活，达到低碳生活的标准。总之，低碳生活，既是保护环境，也是拯救自己。我倡议：让我们大家一起努力，从生活的每一件小事做起，构建一个美好的低碳社会，让我们的生活更加美好。

Therefore, the study of the impact of air pollution, awareness of the value of clean air is a very complex frontier research project. And children in the growth and development stage, is the most sensitive to the outside world air pollution, the study of air pollution on children more likely to obtain valuable results. Based on this, the Chinese Academy of Engineering, China Environmental Monitoring Station Chief Engineer Wei Fusheng for the Chinese chief scientist of the Sino-US scientific and technological cooperation projects one by one air pollution on the impact of human respiratory health research, in Guangzhou, Wuhan, Lanzhou, Chongqing and other cities and suburbs The results showed that 8196 questionnaires were used to investigate the pulmonary function of children in the air, including environmental monitoring data, and about 3 million data were obtained. After statistical analysis, Air pollution has a quantitative understanding of the effects of human respiratory health (especially children). The results confirmed that the impact on human health to the fine particles of air pollution is most serious (China has 2/3 of the city exceeded), followed by sulfur dioxide pollution (1/3 of our city exceeded), the impact of nitrogen oxide pollution relative Weak. It can be said that fine particles (respirable particulate matter) is the first killer of human health. According to experts, particulate matter attached to the toxic heavy metals, acidic oxides compared with the soil enrichment hundreds of times, thousands of times, or even tens of thousands of times, and can float in the air up to several days, harmful substances with the inhalation Particles into the human lungs, and may through the alveolar into the blood, directly endanger human health.

Recently, the eight-year research results in Beijing adopted by the State Environmental Protection Administration presided over the expert appraisal. Experts believe that this research results for our understanding of the importance of clean air, improve the public and the leadership of environmental awareness is of great significance. The data of the research results provide a scientific basis for the national air environment legislation, the development and revision of air quality standards, emission standards and air pollution control policies.
