保护大熊猫的方法英语作文优秀20篇

在我们当前的小学英语教学中，教师往往只组织大量的听、说、读的活动，而忽视对写的有效训练;就是在训练“写”，也只是写写单词、写写句型和课文，并没有深入到培养学生“写”的综合技能。部分教师甚至还存在着一些错误的认识，认为写作教学和训练过于费时，影响教学进度;写作作业难批改;写作教学枯燥，易降低课堂的活力;英文写作对小学生而言太难了等等。但是，儿童语言能力的发展是综合的，听、说、读、写各项能力之间互相制约，互相促进，任何一项能力的滞后都会影响到其他能力的发展。我们应该更新教学观念，设计一些符合学生认知规律、实效性较高的写作活动，促进学生英语技能的全面发展。下面是我对小学英语写作教学一些浅显的看法。

一、 由易到难，培养学生的写作兴趣

对于小学生来说创造性地运用语言确实有一定的难度，所以在写作教学中，教师应针对儿童的年龄特点和语言水平，设计难易适中且充满童趣的写作任务。俗话说得好，兴趣是最好的老师。要培养学生对英语写作的兴趣，首先就要有对英语学习的兴趣。而且要将低、中年级学生的直接兴趣慢慢培养成高年级学生的间接兴趣。尤其是对于低年级的学生词汇量有限，教师更要根据教材的主题或语言内容设计学生易完成的写作任务。如对于中年级的学生，教师可能将阅读材料中的一些关键词或词组挖空，让学生联系上下文猜词填空。如通过填词练习让学生描述动物：

My pet

I have a _______. It is _______ and ________. It has got _____. It has got _______ and ________. It can ________. It can _______, too. It eats _______. My parents like _______ very much. We are ______ friends.

这种填词的练习，既能训练学生的阅读能力，又能培养学生初步的语篇意识，并为高年级的写作打下了基础。循序渐进的学习，既能让学生体验成功，也能让学生建立写作的信心和兴趣。

二、抓好课本教学，夯实英语基础

要想写好一遍好的英语作文，离不开单词的积累。单词是一篇作文最基础的部分，过分强调它是不妥，但却也不能忽略。强大的单词积累是写好一篇作文的后盾。所以，不管在课堂上，还是在课后，都要强调学生掌握好单词的拼写和单词的运用，夯实英语写作的基础。

在小学，学生的主要学习时间是课堂学习时间。学生的主要知识来源于课本，课本是学生学习的根本。课本给学生提供基本的句型,语法知识，词汇等。所以，对于课本中的内容，可适当要求学生背诵，小学生善于模仿，通过背诵课文，一些句子就会在学生心中生根发芽，学生就会有意无意地模仿这样的句子进行写作。课文中的句子一般来说是很规范的，学生的写作也会较规范。记忆中的课文也是学生写作时句子处理的依据。凭语感和课文结构，利用个人的智慧和对作文题目及要求的理解，学生会写出语法正确，句意通顺，结构严谨规范的作文。

三、 广泛阅读，拓展知识面

古人云“读书破万卷，下笔如有神” ， 阅读是写作的基础，大量的、广泛的阅读，才能加强学生理解和吸收书面信息的能力，有助于巩固和扩大学生词汇量，增强语感，丰富学生的语言知识，了解英语国家的文化背景。实践证明，学生平时课外阅读面越宽，语言实践量越大，运用英语表达自己的能力就越强。通过日积月累的积累，学生在自然的习得中学得大量了的英语单词、句子，形成较好的语感。为学生更好地写作打下了坚实的基础。但在选择课外阅读材料时，还要注意：文章太易，不利于知识的提高，文章太难会挫伤学生阅读英语的积极性。这就需要教师做好充分的阅读准备，选择好难易适中的文章

广泛的英语阅读还可以让学生尽可能地了解英汉差异。许多学生写英文短文，都习惯用汉语去思考。写出来的句子，读起来很拗口，句意生硬，令人费解。甚至有的学生将汉语句子逐一对照译成英语单词，拼凑成句子。如：上个星期天，我爸爸坐船去了上海。译文成了：Last Sunday ,I father sit ship go to Shanghai. 令人啼笑皆非。究其原因是学生不明白英汉两种语言表达上的差异。如，汉语中没有时态和语态的复杂变化，只借助于助词“着，了，过”。而英语则有复杂的时态和语态变化以及动词短语，介词短语等一些固定搭配，动词与其主语的一致，称谓的一致等等。让学生进行广泛的英语阅读可以降低这样尴尬的机率，在不断的阅读中拓展知识面。这样才能在实际运用中应用地恰到好处，英语写作才能更规范，更标准，更符合英美人的表达习惯。

四、培养学生的写作热情

众所周知，写作和口语都是语言输出的重要方面。写作是人们学习、运用英语的综合技能的表现，教授学生英语写作能够检验和巩固学生综合的语言知识，在写作过程中，学生有一定的时间去思考、组织、修改、判断，有利于培养和提高学生的语言综合能力;能让学生去辨别口语语体和书面语体的异同，尤其是不同的句型、表达方式和选词造句;能增强学生的自信心，哪怕正确地写出一句、两句话或一小段，一旦受到鼓励，学生都会欣喜若狂，学习英语的兴趣会更加强烈;有利于培养学生直接用英语思维的习惯，尤其是限时写作，学生必须在规定的时间内完成规定的内容，他们就不可能先用母语思考，再译成英语，而是直接用英语来思考;写作可给予学生发挥自己的想象力和创造力，作为老师应仔细观察并珍惜学生的每一次创举，并能及时地对该同学给予肯定和高度赞扬，鼓励他大胆地、尽情地去想象，那么学习英语就没那么枯燥了，写作的热情也会日渐高涨了。

积极带领学生参加教育在线，让他们把自己的作品放在网络上，一方面向别人学习的同时也可以感受到众人欣赏自己作品的那种欣喜;选择优秀的学生作品进行投稿，如《双语阅读》和《小学生英语报》等这些学生常见的刊物，对作品发表的同学进行奖励，这样更能够激发他们的写作欲望。

五、由浅入深，开展扎实的写作训练

写作和任何形式的知识一样都是可以通过训练加以提高的。基础知识和能力并重，听、说、读和写并举。在平时的教学中可应充分利用一切可以利用的机会启发、引导学生提高自己的写作水平。如遇到优秀的句、段或篇提示学生注意欣赏作者的表达法，把它们作为范例，在自己写作中加以模仿和运用。又如遇到英汉表达方法不同之处，提示学生注意英语的正确表达法，切忌出现汉语式的英语。要帮助学生养成正确运用标点符号的好习惯，切忌一点到底的错误方法。

1、坚持循序渐进的训练原则。

用学过的词、短语或句式，模仿课文中的表达法造句。换课文中的人物、时态、语态或体裁等改写课文。将打乱顺序的句子按事件发展的时间顺序或逻辑关系等整理成一篇完整的短文。总而言之，写作要先易后难，先短后长，先写好正确的句子逐步过渡到围绕一个人、一件事、一个观点去写有中心的文章，由不限定时间到限定时间，由限定字数少到多，由一句话日记到一段话日记，由看图作文到命题作文，经过日记，看图写作的训练，学生在写作能力上有了一定的提高，英语表达能力也有很大的进步。这时，可根据学生的教材，就每个单元不同的学习内容提供一个命题作文给学生练笔。这些题目紧扣他们学习的内容，书本上的内容给他们写作提供了模仿的对象，而且跟他们的生活也息息相关。

2、分层要求，注意讲评，鼓励优秀，耐心帮助差生。

对学生的要求不能一刀切，对学习好的要求要高，对学习差的要求要适当低一些。充分利用板报、专栏进行优秀作文展览，经常帮助差生树立信心，掌握写作方法和技巧。英语作文讲评过程中要经常指出优点，以利模仿，指出缺点，警示避免。在训练写作时，要少给学生完整的范文。因为如果经常给学生范文，很容易让学生产生依赖性，不愿意自己动手去写。而是等着老师念范文，自己去背。长此以往学生肯定会背烦的，背烦了就更不愿去写了。会造成一个恶性循环。不利于提高学生的写作水平，更不用说培养语言能力了。

3、小组合作，共同提高

对于一些难度较大、范围较广的写作内容，可以通过开展合作写作来完成。在合作写作的过程中，他们有机会互相交流，集思广益，取人之长，补已之短;他们可能学习写作，指导写作，分享作品。例如：在六年级教学My favourite festivals 这一主题时，让学生以小组形式搜集各节日的有关资料，然后集体讨论，一人执笔写作，最后交流。在合作中写作，既给学生留有独立思考的空间，又可促进他们互相帮助与学习。

4、适当指导

学生动笔写作前，教师要给予必要的指导，不是给个题目或者一幅图，就要求学生动笔写。为了使他们少犯错误。教师还要经常性地列举错误的表达法，提醒学生注意避免。在批阅作文时教师要随时标出学生错误之处，并要随时记录学生所犯错误，把学生的错误加以归类总结，把普遍性的错误提出来，让学生集体改错，使他们的语言表达尽可能的正确规范。

六、鼓励学生资源共享，共同进步

在平时的教学中，我鼓励学生大胆地阅读课外英语资料，鼓励学生搜索网上的英语资料，学生的作品通过不同的方式与读者交流，读者包括教师、同学和家长。让学生各自交流作品的方式有朗诵、出墙报、制作英语小卡片，制作手抄报，写好读书笔记等，将全班学生的手抄报装订成册，搜集全班学生的各种作品，本班学生的作品互相交流，同年级不同班的学生作品也互相交流阅读，集中群体的智慧，内容丰富多彩，五花八门，既适合他们的年龄特征又能供学生课余阅读，拓展视野，达到交流学习的目的，我还设想将学生的电子手抄报发送到我校校园网，以供更多的学生欣赏。除此之外，在评价学生的写作作品时，做到有的放矢，灵活有序，实施本人评价、小组评价，家长评价和老师评价，对学生的进步及时充分的肯定。

总之，英语写作需要平时一点一滴的积累，每一步都不能少，持之以恒的训练。作为英语教师，需要不断的探索和总结。

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.

Children， you grabbed the small tadpoles right， you must know that tadpole grew up to become small frog， the frog can eat insects， so the frog is our humans good friends。 We should protect it， not hurt it。 But some hotels are also sold the frog meat？ Once， dad and his friends took me to dinner。 A waiter said： "you see， this is we store the launch of new specials， stir flogs ball"。 "Chicken is what ah？" I curiously ask， "chicken is the frog。" The waiter said， with a smile。 I was very angry， because they hurt our good friends—frog！ Another thing， he makes a big inspiration。 One day， when I finish school， saw a man at the school gate at little chicks must sell， and I will have mercy on them。 Because the little chicks must first came to this world， away from the mother， away from the mother love and mother warm embrace， and this is what they faced starved to death， the risk of freezing to death。 At that time I thought： we humans are so happy！ When you see here， did you see to protect our human friends—animals！

Everyone can do something for our environment.What Can I Do for Our Environment?

每个人都可以为我们的环境做些事情。我可以为我们的环境做些什么呢?

Everyone can do something for our environment.As a student, we should build the sense of frugality in our daily life in the school.I always turn off the lights in the classroom when I leave.Both sides of the paper can be used if it is possible.After school, I bear the consciousness of environment protection in mind.In order to protect the forest I often refuse to use the paper cups and disposable chopsticks consciously.I believe that individual contribution to the environment will build a more beautiful world.

每个人都可以为我们的环境做些事情。作为一名学生，我们应该在学校的日常生活树立节俭意识。当离开教室的时候我经常把灯关掉。如果可能的话，纸张的两面都可以利用。放学后，我时刻把环保意识牢记在脑海中。为了保护森林我经常有意识地重复利用纸杯和一次性筷子。我相信，个人对环境的贡献将建立一个更美好的世界。

我的家乡是一个物产丰富，花草茂盛的地方——山东.

我经常和邻居家的小弟弟去小溪边玩，有一次，我骑着自行车带着小弟弟去小溪边玩，这里的溪水清澈见底，花草也长的非常茂盛，溪里的贝壳好看极了，有黄色的，有绿色的，有黄色的，怎么数也数不清，我和小弟弟经常在这里打水仗。

可是，在我六岁时，我又一次骑着自行车，带着小弟弟去小溪边玩时，我看到了家乡的小溪发生了很大的变化：溪水变得又黑又臭;贝壳看不到了;小鱼都死了，浮在水面上;又有一些垃圾在水面上漂浮着。看到这场景后，我和小弟弟都惊呆了。

我决定在每年的春天，我都和爸爸妈妈回家乡种几棵树，和家乡的小朋友们共同发起“养一盆花，栽一棵树，爱护每一片草地，不乱丢垃圾”以及让我们的爸爸妈妈“放下方便袋，拿起菜篮子”的倡议。

虽然，我们现在做的只不过是一些鸡毛蒜皮的小事，但是我相信，只要我们人人都有保护环境的责任心，那么我们就会看到一个干净又美丽的世界!

这里有一些建议给你。首先,不长时间看书或者看报纸这是一个好习惯,因为我们的眼睛需要休息。其次,不在光线强或光线差下看书,否则,光会伤害我们的眼睛。最后,记得要坚持做眼保健操,看更多的绿草和其他植物。

In recent years, I find it easier to our resources dried up. All of these, because we have recently a lot of collection resources, leading to our mothers are dwindling.

What is the mother of all resources less and less? Is, of course, we humans excessive spoiling dont cherish, would cause such a serious result. Our earth forest area has reached 600 million hectares, the figure is due to our human previously has important sense to protect the environment, know that if you dont have a good environment, we wont be able to breathe to the light wind gently brushed the grass surface sweet taste. And now? Us that the earths forest area is still not arrived 6 hectares, this kind of situation, it is because we humans cut down trees and destroying forest without restraint, make almost fell by 1% in each of the forest area in the world, now our protection in the nature of the important consciousness is more and more shallow, dont take care of the objects around, as the forest is less, the first bite of the air we breathe is less and less fresh...

Is not destruction of forest resources, and our mineral resources. It is limited, now our production technology constantly improve, the accelerating speed and shortage of some minerals occurred, even dried up. Until then, we will always stay in the desolate landscape.

In the face of these, can see there are so many resources in we lost too much! We rely on resources too much! All around us, little drops of the resources are in decline, if lost it all, we will how to live! So, let us sincerely treat our mother earth, try to cherish, to cherish. If only use a small plastic bag, it should not be too!

Let us act, to defend the earth!

近几年来，我发现我们的资源越来越容易枯竭了。这些，都是因为我们最近大量的采集资源，才导致我们的母亲日渐枯竭。

是什么让我们这位母亲的资源越来越少了呢?当然是我们人类过度的糟蹋不珍惜，才会造成这样严重的结果的。我们的地球森林面积曾经达到了6亿公顷，这笔惊人的数字是由于我们人类以前有着保护环境的重要意识，深知如果没有了良好的环境，我们也就无法呼吸到微风轻拂过草面的甜美味道。而现在呢?我们地球的森林面积还不到了6公顷，这种状况，就是因为我们人类不加节制地砍伐树木和毁林开荒而造成的，使世界上的森林面积几乎每年减少了1%，现在我们的保护在自然的重要意识越来越浅，不爱护身边的一草一木，由于森林逐渐变少，我们呼吸的第一口空气也就越来越不清新……

还不止森林资源被破坏，还有我们的矿产资源。它是有限的，现在我们的开采技术不断提高，速度不断加快，使某些矿种发生短缺，甚至面临枯竭。到那时，我们将永远呆在荒凉的大地上。

面对这些，可以看出来我们失去的资源真是太多太多了!我们的依赖的资源也太多了!在我们身边，点点滴滴的资源都在减少，如果失去了这一切，我们将如何生活!所以，让我们真心地善待我们的地球母亲，努力去珍惜，去爱惜。哪怕只是多用一个小小的塑料袋，这也是不应该的!

让我们行动起来，保卫地球吧!

就“说明对象”而言，英语说明文可分为对“客观具体事物”的说明和对“主观抽象观念”的说明两大类，比如：对“LASER（激光）”、“Computer Problem of Year XX（计算机XX年问题）”等等的说明都是对客观或者具体事物的说明，而“The Successful Interview（谈成功的面试）”、“How to Write Good English Composition（如何才能写好英语作文）” 等是对主观抽象观念的说明。对我们中学生朋友来说，在汉语说明文的教学中似乎比较侧重前者，即解释客观具体事物的说明文。但在英语说明文中，阐述和说明 “主观抽象观念”的说明文占了很大的比重，其中有些类似汉语中的议论文。但是无论是对“客观具体事物”的说明还是对“主观抽象观念”的阐述，英语说明文从结构上看大致可分为三个部分：第一部分一般是文章的第一段，提出文章的主题，也就是说，文章想要阐述、说明的主要内容；第二部分是文章的主体，可由若干个段落组成，对文章的主题进行展开说明；第三部分是结尾段，对文章的主题作归纳总结。从英语说明文的结构可以看出，要写好英语说明文的关键在于第二部分如何对文章主题进行展开说明。在英语中，常见的用来展开文章主题的方法有下列几种：

1.罗列法（listing）

在文章开始时提出需要说明的东西和观点，然后常用first，second，…and finally加以罗列说明。罗列法广泛地使用于各类指导性的说明文之中，下面这篇学生作文就是用罗列法写成的：

Early Rising

Early rising （早起） is helpful in more than one way. First， it helps to keep us fit （健康）。 We all need fresh air. But air is never so fresh as early in the morning. Besides， we can do good to our health from doing morning exercise （做早操）。

Secondly， early rising helps us in our studies. We learn more quickly in the morning， and find it easier to remember what we learn in the morning.

Thirdly， early rising enables （使能够） us to plan the work of the day. We cannot work well without a good plan. Just as the plan for the year should be made in the spring， so the plan for the day should be made in the morning.

Fourthly， early rising gives us enough time to get ready for our work， such as to wash our faces and hands and eat our breakfast properly.

Late risers may find it very difficult to form the habit of early rising. They ought to make special efforts to do so. As the English proverb says，“Early to bed and early to rise， makes a man healthy， wealthy and wise.”

罗列法经常用下列句式展开段落，我们可以注意模仿学习：

There are several good reasons why we should learn a foreign language. First of all， …Secondly， …And finally， …

We should try our best to plant more trees for several good reasons First of all， …Secondly， …And finally，

必须指出的是，有时罗列法并不一定有明确的first， second…等词，但文章还是以罗列论据展开的。

2.举例法（examples）

举例法是用具体的例子来说明我们要表达的意思，常用for example， for instance， still another example is…等词语引出。下面这篇学生作文就是用举例法写成的：

Recreation

It is impossible to keep in good health unless we take enough recreation （娱乐）。 The mind， too， needs change to make it fresh and vigorous （有活力的） There is much truth in the old saying， All work and no play makes Jack a dull boy.“

There are many games which boys and girls can play after their school work is done， for instance， football， tennis， and kite-flying. Other examples of recreation are boating， fishing， gardening， cycling， walking， chess-playing， and reading. Persons who sit much at their business should take a kind of recreation that will supply their muscles （肌肉） with exercise. Those who spend most of their time in the open air and do manual work （体力活） should adopt （采纳） reading or some other quiet form of recreation.

Cycling is said to be an important means of recreation， but many persons foolishly tire out themselves by cycling too much. The same may be said in regard to football. Tennis is a pleasant form of recreation. Many persons take great delight in boating. Fishing requires much patience， and there is much danger of taking cold by sitting still on a cold day too long. A good brisk （轻松） walk is one of the finest forms of exercise. For persons engaged in outdoor labor， chess-playing is another excellent form of recreation.

可以看出，举例法和罗列法有时可以结合使用：即用罗列法来列出例子，用例子充实罗列的说明。

3.比较法（comparison and contrast）

比较法是对两个对象进行比较，从而进行说明的写作手法。比较法又可细分为比较相同点（comparison）和比较不同点（contrast）两种方法，比如：

From Paragraph to Essay

Although they are different in length （长度）， the paragraph and the essay are quite similar in structure （结构）。 For example， the paragraph starts with either a topic sentence （主题句） or a topic introducer followed by a topic sentence. In the essay， the first paragraph sets up the topic focus （主题所在） Next， the sentences in the body of a paragraph develop the topic sentence. Similarly， the body of an essay consists of a number of paragraphs that discuss and support the ideas given in the introductory （引导的） paragraph. Finally， a concluding sentence （结束句） ——whether a restatement， conclusion， or observation——ends the paragraph. The essay， too， has a concluding paragraph which ends the essay logically and satisfactorily. Although there are some exceptions （例外）， most well written expository （说明文的） paragraphs and essays are similar in structure.

可以看出，在比较相同点的时候，常用到similarly，also，too，in the same case，in spite of the difference等这样的词语。

European Football and American Football

Although European football is the parent of American football， the two games show several major differences. European football， sometimes called association football or soccer， is played in 80 countries， making it the most widely played sport in the world. American football， on the other hand， is popular only in North America （the United States and Canada）。 Soccer is played by eleven players with a round ball. Football， also played by eleven players in somewhat different positions （位置） on the field， is played with an elongated （拉长的） round ball. Soccer has little body contact （接触） between players and therefore needs no special protective equipment. Football， in which players make the greatest use of body contact to stop a running ball-carrier and his teammates， needs special protective equipment. In soccer， the ball is advanced toward the goal by kicking it or by butting （顶） it with the head. In American football， on the other hand， the ball is passed from hand to hand or carried in the hands across the opponents （对手） goal. These are just a few of the features which distinguish （区别） association and American football.

这是一篇用比较不同点的手法写的说明文。从文章中可以看出：however，on the other hand，in contrast，but，nevertheless等表示转折的词语常用来引导对不同点的比较。

4.定义法（definition）

定义法也是英语说明文中常用的写作手法，特别是在对具体事物概念进行说明时经常使用。定义法的基本要素是定义句。英语中常见定义句的模式是：

被定义对象is所属类别+限制性定语

可以看出，定义句中限制性定语越详细，定义就越精确，比如：

A bat is a small mouse-like animal that flies at night and feeds on（以……为食品）fruit and insects but is not a bird.

其实，在英—英词典中，对英语单词的英文解释就是定义法的典型例子。比如，看看Longman词典对student和teacher的定义是很有意思的：A student is a person who is studying at a place of education or training. A teacher is a person who gives knowledge or skill to sb. as a profession （专业）。

5.顺序法（sequence of time， space and process）

顺序法是指按时间、空间或过程的顺序进行说明的一种写作手法。比如按照时间顺序介绍一个科学家的生平，用空间顺序阐述逐渐开发西部的重要意义，用过程顺序法解释葡萄酒的生产过程等等。

下面这篇学生作文就是用顺序法写成的：

Coal

Coal underwent （经受） many changes before it became the bright， brittle （脆的）， black substance which we now use. During ancient times （在上古时代）， when the earth enjoyed a very warm and wet climate， the land was covered with large forests and big plants. As time went on， the ground changed and began to sink （下沉） a little. These very large numbers of trees and vegetables received a deposit （沉淀） of sand and clay. This layer of sand and clay pressed upon the layer beneath and prevented it from contact with air. These trees and plants received the pres sure and changed its appearance.

Generations after generations （几世纪后）， as the ground kept gradually sinking， another layer of sand and clay was again deposited （积聚） above the layers already formed. A great pressure was thus exerted （作用） and the peat （泥煤） was changed into the black and brittle substance which is known as coal.

Coal is a kind of mineral which is formed by nature as above stated. It is an important industrial material and is chiefly used as fuel. It is very valuable in the industrial world. The place where coal deposit is called a coal mine （煤矿）。 In China， coal mines are largely found in the north-west part of the country. Shanxi is a famous province for producing coal. It has the most coal of China.

6.分类法（classification）

分类法是将写作对象进行分类说明的一种写作手法。比如：著名的英国哲学家弗朗西斯·培根（Francis Bacon）在其脍炙人口的《谈读书》（Of Studies）一文中就用到了分类法：

Some books are to be tasted， others to be swallowed， and some few to be chewed and digested， that is， some books are to be read only in parts， others to be read， but not curiously， and some few to be read wholly， and with diligence and attention. Some books also may be read by deputy， and extracts made of them by others； but that would be only in the less important arguments， and the meaner sort of books…

参考译文：书有可浅尝者，有可吞食者，少数则须咀嚼消化。换言之，有只须读其部分者，有只须大体涉猎者，少数则须全读，读时须全神贯注，孜孜不倦。书亦可请人代读，取其所需摘要，但只限题材较次或价值不高者……

——转摘自《英汉翻译教程》（张培基等）

可见，如果能够根据具体情况，选用合适的写作手法，就可为文章增添无穷的魅力。

除了上述提到的6种展开英语说明文主题的写作方法之外，还有因果法、归纳法等其他方法。但相比之下，对于中学生来说，上述6种方法是首先值得掌握的。另外必须指出的是：在一篇文章中往往是以一种写作手法为主，同时辅以其他写作手法。有时，甚至会几种写作手法混用而不分主次。因此，必须根据具体情况，选用合适的展开主题的写作手法，才能写出优秀的英语说明文。

Traffic and Protecting Environment

交通与环保

2015年11月，全国中东部地区17省市持续雾霾，陷入大范围的重度和严重污染。造成这一现象的主要原因是工厂排出的废气和汽车尾气等。绿色低碳，保护环境，从我们身边小事做起。现请你根据以下三个方面的提示，以"Let’s Do Something to Save Our Environment"为题写一篇80词左右的短文。

内容包括：

1.重要性：只有一个地球。2.主要问题：污染、疾病、灾难。3.措施：停止污染、保护大自然。

Let’s Do Something to save Our Environment

We all live on the earth. The earth is our home. We have only one earth. We must take care of it. It gives us the best environment. If we harm it, it will be angry. And then we will have a terrible end. There are three problems in our earth, they are pollution, disaster and illness.

It’s our duty to protect our environment. So we must plant more trees, protect the flowers and the trees, save energy, reduce the pollution. We should ask our government to control the pollution from the factories.

Protecting the nature is very important. It’s our duty to keep our environment clean and tidy.

If everyone makes a contribution to protecting the environment, the earth will become much more beautiful.

Historically, many people have to kill animals at all costs. Take former guangdong, for instance, they are the most like to eat wild raw monkey brain, at that time, they get rid of skull live monkey dont feel cruel. For those too poor...

Now, in the zoo, we tend to see "please dont feed the" slogan. In order to let the passengers dont cast a prank. Once, an animal is eating the passengers throw plastic bags, ill.

So called for everybody, please protect the animals, wild animals less and less now let our home full of vitality!

地球上一片生机勃勃，到处都是可爱的生命。生命需要我们去珍惜，我们去保护。

人有生命，动物也有生命。

公元前出现了猿人，对于现在，有些人认为，他们只是会群居的动物。其实，说这话的人，也就是他们演变而成的。

从古至今，许多人曾不择手段的捕杀动物。就拿以前的广东人来说吧，他们最喜欢生吃野生猴脑了，那时，他们把活生生的猴子的头盖骨去掉也不觉得残忍。可怜了那些猴儿啊……

现在，在动物园里，我们往往会看见“请不要喂食”的标语。就是为了让旅客们别投搞恶作剧。一次，一只动物就是吃了旅客投的塑料袋，生病了。

所以，呼吁大家，请保护动物，现在野生动物越来越少了让我们的家充满生机吧!

保护环境英语作文篇1

Environmental pollution can cause direct damage and impact to ecosystems, such as desertification and forest damage, which can also cause indirect hazards to ecosystems and human societies. Sometimes the harm of this indirect environmental effect is greater than the direct hazard caused by it, It is more difficult to eliminate. For example, the greenhouse effect, acid rain, and ozone depletion are the environmental effects derived from atmospheric pollution. This environmental effect derived from environmental pollution is lagging behind, often at the time of the occurrence of pollution is not easy to be perceived or expected, but in the event of environmental pollution has been developed to a very serious point. Of course, the most direct and most environmentally conscious consequence of environmental pollution is the decline in the quality of the human environment, affecting human quality of life, physical health and productive activities. Such as the citys air pollution caused by air pollution, peoples morbidity and so on; water pollution so that the deterioration of water quality, drinking water quality generally decline, threatening human health.

环境污染会给生态系统造成直接的破坏和影响，如沙漠化、森林破坏、也会给生态系统和人类社会造成间接的危害，有时这种间接的环境效应的危害比当时造成的直接危害更大，也更难消除。例如，温室效应、酸雨、和臭氧层破坏就是由大气污染衍生出的环境效应。这种由环境污染衍生的环境效应具有滞后性，往往在污染发生的当时不易被察觉或预料到，然而一旦发生就表示环境污染已经发展到相当严重的地步。当然，环境污染的最直接、最容易被人所感受的后果是使人类环境的质量下降，影响人类的生活质量、身体健康和生产活动。例如城市的空气污染造成空气污浊，人们的发病率上升等等;水污染使水环境质量恶化，饮用水源的质量普遍下降，威胁人的身体健康等。严重的污染事件不仅带来健康问题，也造成社会问题。随着污染的加剧和人们环境意识的提高，由于污染引起的人群纠纷和冲突逐年增加。

让我们都来关爱自然，热爱地球吧，手挽手、肩并肩、心连心地铸起一道绿色环保的大堤，捍卫资源、捍卫环境、捍卫地球、捍卫我们美好的家园吧!

Environmental problems are becoming more and more serious all over the world. With the development of industry and agriculture, cars make great noises and give off poisonous gas. Trees on the hills have been cut down, and waste water is being poured continuously in to rivers. Furthermore, wherever we go today, we can find rubbish carelessly disposed. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even poses a great threat to mans existence.

保护环境英语作文篇3

People like to modernize the building compared to the magnificent, then this embodies a high degree of spiritual civilization and material civilization of the building should stand in what kind of environment? If the sky filled with smoke, the earth vegetation and so on, this is the people of the modern society of it? No, no, it is the irony of history, this is the tragedy of mankind.

People live on earth, to survive, to develop, first of all have to rely on the earth, by mountains and water, there are grassland nature of the forest. But some people mistakenly believe that nature is inexhaustible treasures, so deforestation and species, dried Ze and fishing, and even by the natural punishment and not know. Year after year, the forest into a barren hills, oasis into a desert, resulting in the world every year, 2,000 hectares of farmland was swallowed by the desert. So go after a few years, the earth will be all occupied by the desert green, our children and grandchildren will not survive! A few years ago, the rural package to the household, coax the mountain into the wind, Chinas Wuchuan County, a township of nearly 2,000 acres of fir forest, cut in a week for the ground. Hearing this news, I have a headache, I am angry, the farmers doing so are too ignorant and too selfish. There are a lot of things that are doing the same thing: it is the smoke of the sky, so that the noise of high decibels can stimulate the nerves of the people.

In this regard, we should think deeply. Modern society makes us live better, modern science has also fully revealed the importance of environmental protection. Every honest citizen should have such a historical vision and sense of urgency: to build our country into an ideal modern power, we must do the development of economic and environmental protection simultaneously, to achieve economic development and social benefits of unity.

人们喜欢把现代化比作宏伟的大厦，那么这座凝聚着高度精神文明和物质文明的大厦应矗立在怎样的环境之中呢?如果天空烟雾弥漫，大地草木枯败等等，这是人们心中的现代化社会吗?不，不是，这是历史的讽刺，这是人类的悲剧。

人生活在地球上，要生存，要发展，首先就得靠地球，靠有山有水，有森林有草原的大自然。可是有人误以为大自然是取之不尽，用之不竭的宝库，于是毁林而种，竭泽而渔，连连受到自然的惩罚而不自知。年复一年，森林变成了荒丘，绿洲沦为沙漠，致使世界上每年有2000公顷农田被沙漠吞噬。这样下去经过若干年，地球上的绿地将全部被沙漠侵占，我们的子孙将无法生存!前些年，农村包产到户后，哄砍山林成风，我国务川县一个乡的近2000亩杉木林，在一周之内被砍为平地。听到这个消息，我头疼，我愤怒，这样做的农民太愚昧，太自私。还有很多正在干着类似务川的贻害子孙的事情：任滚滚浓烟弥漫天空，让高分贝的噪音刺激人的神经。

对此，我们应该深思。现代化社会使我们生活得更美好，现代科学也已充分揭示了环境保护的重要性。每个正直的公民，都应具备这样的历史眼光和忧患意识：要把我国建成一个理想的现代化强国，必须做到发展经济与保护环境同步，实现经济发展效益与社会效益的统一。

事实也是这样，几年前，大连污染严重，经过一系列的保护措施后，不仅使市容面目美观了，还带来了良好的经济效益，外商投资，中外合作等等，因此让大连成为现代化的大都市。

让我们伸出自己的双手，来保护自己的家乡，来建设自己的家乡吧。

There are more high-rise apartment buildings built in the city we live to accommodate more city dwellers. To make room for these constructions, a large number of trees are cut down. We have to be constantly afflicted with the noise and air pollution everyday. Obviously, we are paying the cost of the development.

Even the most developed countries are troubled with environmental issues. In fact, the more developed the country is, the severer the problem has. To maintain our economy prosperity and stability, we have to be in full operations and spread the workload in industry fields. As a result, we may seek temporary economic development at the expense of the environment and resources. The consumption of natural resources has been a big problem. It is admitted that the world economy is booming with the satisfaction of environment. However, we have made a blunder by equating material prosperity with better living standards.

A better life should be a life closer to nature. The modern lifestyle is best characterized by hectic, mass-productive and seemingly comfortable. But actually something originally natural and invaluable has been lost. We are no longer able to breathe fresh air, take a walk in the woods or even look at the stars in the sky as the stars are obscured by smog and artificial lights.

Hence, we need to curb the quick tempo of life in order to protect our environment and ironically improve our life. Science and technology thus should be employed to create a harmonious relationship between mankind and nature. A better environment means much more than material comforts. Besides, by slowing down a little bit, our life would turn out to be less stressful. To have a better life, we need take effective measures right now.

The current environment damage stems from the misguided conception that material wealth is equivalent to a better life. In reality, environmental protection serves as the catalyst of our very pursuit of better life rather than a deterrent 关于环境保护的英语作文2

Many people believe that we have developed into a “throw-away society” which is filling with plastic bags and rubbish. What do you think?

Wind blows up bags higher and higher in the sky. It is a scary thought that some day the earth will turn into a huge garbage land. Wastes, if not treated properly, will make our life a living nightmare.

The environmental issue is getting worse almost every day in cities with very large population. As is often the case, city development outpaces environmental protection. People consume great amount of natural resources and produce wastes. To effectively address such problems, cities need to spend big money. In addition, they need to call to the attention of people to become more environmentally responsible.

Many people are becoming less responsible and easily influenced by bad behaviors. “Why should I care while others shouldn’t?” Such idea makes some people only concern with places where they live and work. Furthermore, people sometimes even purposely litter for revenge to other people.

Although media promotes environmental awareness, good people are often snubbed as posers who try to set up a superior image in real life. Consequently, they are intimated of receiving negative comments for doing the right thing. Wrong as it is, such phenomenon is widespread especially among youngsters and people with low income and little education.

However, our society is waging a campaign against environmental pollution. People learn the harms of un-degradable lunch boxes and other polluting wastes. Laws in many countries prohibit or limit excessive use of polluting bags. Companies are continually replacing the old materials with more environmental friendly and recyclable kinds. Scientists have developed more effective technologies in waste treatment. As time goes by, more and more people put high priority on the protection of environment for a healthier life.

To sum up, people produce huge amount of garbage and the environment is seriously polluted because of lack of financial resources, sense of responsibility, or efforts. But the world will not turn into a “throw away” society if people put in sufficient efforts to protect our environment

If someone asked me, whats your favorite animal? I will not hesitate to say to you: "I like the lovely giant pandas."

It stood up slowly, after waking up, rubbing his sleepy eyes, and looked at the people, as if to say: "all looking at me? How dont go to the other animals? How strange!"

From then on, I prefer the lovely giant pandas.

如果有人问我，你最喜欢什么动物?我会毫不犹豫地对你说：“我最喜欢可爱的大熊猫。”

据我了解`，大熊猫是一种濒临灭绝的珍稀动物，还是我国的国宝呢!目前主要生活在我国四川省附近的一些地区。它憨态可掬，惹人喜爱：短短的四肢，胖胖的身子，毛茸茸的面孔上嵌着乌黑发亮的眼睛，更显得美丽可爱。

熊猫一般喜欢在平坦的地面上悠闲的散散步，愉快地玩耍。他有时抬头望着人们，有时又埋着头，好像在寻找什么东西。当它高兴的时候，就在地上翻跟头;当它生气的时候，就躺在地上大大咧咧地睡觉。

它睡觉时非常有趣，腹部朝天，有时，它两腿一蹬就翻了个身，人们还以为它睡醒了呢!其实它还在睡觉。它睡醒后，就慢慢地站起来，揉揉惺忪的眼睛，望着人们，好像在说：“都看着我干什么?怎么不去看别的动物?真奇怪!”

Cars and Air Pollution

Too many cars have created a lot of serious problems in our world. Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. All the time, they are pumping huge amounts of waste gases into the atmosphere. These gases are very harmful, causing disease and even death.

One possible solution is to design and develop clean cars and clean fuels. In Shanghai, some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as the petrol. But it may take decades for the new models of clean cars completely replace the traditional ones. Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not buy private cars. And the total number of cars in big cities will reduce greatly.

On the whole, the elimination of air pollution needs the collective efforts from the government, the public and the environmentalists.
