Many traditional arts are losing nowadays, because some of them have been replaced by the new machines and the scientific products.

I feel so sorry about the losing arts, in my opinion, they are so classic and their charm will never fade away.

Take my grandma for example. She is good at paper-cut which was inherited from her mother.

But when comes to my mother’s generation, paper-cut seems to be kicked out, there are less people need it, so my mother doesn’t learn this skill. The paper-cut art is losing in my family. When I found my grandma had this skill, I was so surprised and curious about it. I asked my grandma to teach me this skill. During the process, I found this art was so great, I was attracted by it. Some traditional arts like paper-cup should be kept.

如今很多传统艺术正在消失,因为一些传统已经被新的机器和科学的产品所替代。对于正在消失的艺术，我感到抱歉,在我看来,他们是如此经典和有魅力,将永远不会消失。以我奶奶为例。

她擅长剪纸，继承了她母亲。

但是当到我母亲这一代,剪纸似乎被淘汰了,越来越少的人需要它,所以我的母亲不学习这个技能。

剪纸艺术在我家中逐渐失去。当我发现我奶奶有这个技能的时候,我是如此的惊讶和好奇。我叫奶奶教我这个技能。在这个过程中,我发现这门艺术是如此之大,我被它吸引住了。一些传统艺术像剪纸应该被保持。

st important role in the environmental protection today.

In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.

my secret worry

while fear of death is universal, my worry about death is so overwhelming that there is not a moment passing without my thinking of it. i never bring this up with any other, just because no one will ever realize the seriousness of this problem. i know it very clearly that as long as there is life, there will be death. in addition, though i am still so far away from death, i have been plagued by the thought of it for years. fortunately, the root of my fear of death lies in my overzealous love for life. i am too timid to think of the end of life, when every worldly affair should be thrown away. how can i carry on without friendship, affection, and joy of being alive? i really hate to leave all these behind. to ease my worry about death, i should make the fullest use of this life i now possess. concentration on this life can at least temporally make me forget about death. as a matter of fact, i really don＇t need to worry so much about death, for i already have too much to worry about this life.

森林的乱砍滥伐不就是一个严峻的问题吗?据调查全世界森林面积正以每年上千万公顷的速度在消失。造成大量的水土流失，使许多地区成为沙漠。人类的活动范围在不断减少，这不可怕吗？以下是小编为大家整理分享的改变污染环境的作文，欢迎阅读参考。

改变污染环境的作文

在21世纪的今天，人类的科学经济发展已经达到了很高的水平。然而我想问：你们有没有意识到人类的活动对环境会造成怎样的影响呢？

森林的乱砍滥伐不就是一个严峻的问题吗?据调查全世界森林面积正以每年上千万公顷的速度在消失。造成大量的水土流失，使许多地区成为沙漠。人类的活动范围在不断减少，这不可怕吗？

人类除了破坏森林之外，难道就没有什么破坏环境的问题了吗?不是这样的。现在我们应该看到水污染的严重性，目前世界上60%的地区面临供水不足，已有20%的人口难以得到清洁水，51%的人无法得到卫生用水。这是什么造成的呢?是我们人类自己造成的，现在的工厂及我们生活中的污水，没有通过处理就排出去。这不是最好的证明吗?据研究，每排放1立方米污水，就污染14立方米天然水。想一想，这是多么可怕的数字？

在工厂排出的浓烟里，我们不知道浓烟是污染大气的吗?科学家发现，至少有100种大气污染物对环境产生极大危害，直接影响人们的健康。

难道我们想在这种环境中生活吗？当然不想；那让我们用行动来证明吧！我们可以从我做起，从现在做起，从身边做起。树立爱自然、爱护环境的意识吧！来做宣传环保的使者!让我们一起为保护环境行动起来吧。

改变污染环境的作文

随着科技的不断发展，汽车的不断增多，排放的废气已经造成了严重的污染，或许，几年后的子孙后代、几百年后的大家，或许会因为大气污染而死亡。现在，地球上每一年都有百分之二十的人因为饮用了受到污染的水而死亡，如果这样延续下去，地球在几万年后岂不是变得光秃秃、像月球一样了？

据科学家的统计，每一年，每一月都有百分之二十多的树木因为废气污染而枯萎。百分之八十多对我们有益的细菌死亡，大家或许会觉得很夸张，但这是事实。其次还有受到污染的废水、废气等。人类有错吗？

我多么希望大家能珍惜我们身边的每一个事物，每一只动物，每一只有益的细菌，因为，很有可能，在几万年后的今天，他们都没有了。

动物对人类发起了警告;细菌对人类发起了警告;每一条无辜的生命对我们发起了警告。

“人类，不要再害你自己，不要再害死我们了吧！”

Dear Tim,

With Spring Festival drawing near, I’d like to invite you to my home to experience the festival.

When you come, we can enjoy traditional Chinese food together, and then put up Spring Festival couplets. As a traditional custom, the couplets are always posted on the door of a house. Written on red paper, a couplet is composed of two lines of poetry, which rhyme with each other. Not only do the couplets add some joyous atmosphere to the festival, but also they express people’s wishes for a better life.

I would appreciate it if you could accept my invitation. Looking forward to your coming.

导语：以下是小编精心整理的高中英语作文教学反思，欢迎大家参考阅读。

高中学生的想象更趋于现实化，创造想象也日益占优势地位。表现 出更大的主动性和有意性，能够运用自己的创造力去解决新的问题。

由于高中学生在英语学习方面有了一定的词汇积累、阅读经验以及掌握了一些基本的语法规则，使他们已初步具备了将心中所思转化为英语文字的能力。在这个阶段，教师如果通过影像、音乐、语言等多种手段，在学生的作文训练中大力发展学生思维的变通性和独创性，那么，学生想象力的提高将会成为可能。

一、利用表象，丰富想象

观察图画和实物作文符合英语作文起步阶段需要有一定的情景要求，也符合高中学生有意想象占优势的特点，同时避免了文字情节作文易使学生中译英的缺点，但若每一次训练都是刻板的再现材料，创造想象则难以增长。如果在教学设计时，在图中留有空白，或对实物设置悬念，不仅可以引发学生的好奇心，激发他们对英语作文的兴趣，减轻他们的惧怕心理，而且可以促使学生通过创造性的想象去填补空白，解决悬念。

如Senior BookⅠ,Unit 3 中的“Help! Help!”，可按发展顺序设计几幅救落水儿童的图，但只给学生展示第一、二两幅图，图画的内容大致与课文内容相同，但是后几幅的空白，使学生必须通过创造性的想象才能填补材料的空白。学生可以引用课文中的材料，也可以自由发挥。有学生这样写到：

Last week, we had a picnic in Forest Park. We found a shady place by the river. As soon as we had sat down, Tom suddenly got up and shouted, “Someone has fallen into the river!" It was true. A boy was struggling in the water, and the children in a boat looked hopeless. Tom and Jack took off their shoes while running to wards the water. They swam very quickly towards the boy who was sinking fast. Tom and Jack got hold of the boy by the arms and lifted his head above the water. Together they pulled the boy to the shore.

之后，再给学生展示其中一幅图，或一句话的情景：……,a man/a woman/a child, etc. has fallen into the river/the lake, etc.……。让学生自由选择自由发挥。有的根据曾在报上看到的新闻，称颂一身怀六甲的妇女勇救落水儿童的事迹，也有的谴责那些对落水者无动于衷的旁观者。学生的作文体裁记叙文、议论文不限。这样，既训练了他们书面的表达能力，又发挥了他们的想象和创造能力、思维表达能力。同时也让他们思索了做人的道理。

二、精选图画，激发想象

处于英语作文起步阶段的学生的想象具有直观性，片面性和模仿性的特点，为其提供的观察材料越具体、越完整、越详实，他们的这些特点往往表现得越明显，有时甚至强化了他们的这些特点。换个方式，为他们提供一些抽象的图画，他们的创造想象反而被激活，因为他们必须在原有的图画上进行创造才可能有新的形象产生。而“抽象画作品所表现的物象与参照物相差甚远，它最大限度地把形与色对视觉作用的潜力发挥出来，直观效果非常强烈。它经过夸张、简化、分解、组合等变化手段，将客观事物的表象创造成为富于想象力。”如荷兰画家蒙德里安的表达百老汇街道的嘈杂与热闹的《百老汇爵士》（Jazz in Broadway）是一幅看上去比较抽象的图画，学生通过观察、运用合理的想象，写出了内容各异的作品。

有学生这样写到：

It is the downtown of Shanghai. The streets, such as Nanjing Road and Huaihai Road, etc are busy. Cars, buses and trucks with all kinds of advertisements are running. People dressed in their best are walking happily or hurrying to work on their bikes. Beautifully decorated stores are crowded with people shopping. They all look in high spirits. The traffic policemen at the crossings are directing the traffic attentively and seriously. Everything is in good order. Such is our city. I love our city.

而另有学生在他们的作文中认为这是一个“排污系统”（drain outlet system ）或电路板（circuit board）或房屋平面图（a plane figure of a house）等等。

可见，由抽象的图画到生动画面的产生，到一篇作文的写作成功，是创造想象不断发展的过程，也是提高英语语言运用能力的过程。

三、借助音乐，拓宽想象

音乐能有效地丰富学生的精神生活，促进学生感知、情感、想象等方面的健康成长，能给学生提供想象和联想的广阔空间，有利于培养学生的发散性思维能力，促进人的全脑开发，为学生的创新精神和实践能力在各方面的延伸乃至终身发展提供良好的基础。因此，在英语写作训练中有时借助音乐等艺术形式，对丰富学生的想象力是一种有益的尝试。

如Senior Book Ⅵ ,Unit 7中的“The Waltz king ”这一课文，根据内容，可设计让学生听一首Beethoven的“命运”(Fate)，让学生根据自己的理解，写一篇作文，一位学生这样写到：

I am a graduate from high school, and I will enter for the Collage Entrance Examination. Whether I will be admitted to a collage, I will work harder than before , since our country is still poor and weak.

从作品中我们可以发现，借助音乐，学生的想象力得到了较大幅度的拓展。“音乐艺术对学生的创造能力的发展具有独特的作用。

四、灵活方法，发展想象

“创造想象是严格的构思过程，它是由思维调节的。”想象会产生全新的物象与情景、独特的认识和感悟。一段文字、一篇文章，给不同的读者，就有不同的想象余地。正如：A thousand readers, a thousand Hamlets.（一千个读者，就有一千个哈姆雷特。）在英语作文教学中根据一定的线索或情节，提供学生广阔的思维空间，让学生进行想象描述（创造性的描述），会收到很好的锻炼效果。

例如 “After Twenty Years" (Senior Book Ⅵ,Unit 5) 这一课，可要求学生在学完之后， 简单续写一个结尾。这是一篇根据O. Henry 同名原作改写的文章。文章的故事情节虽然简单，但很能挖掘、发挥学生的创造想象力。学生这样写到：

As soon as the police officer wanted to catch Bob by the arm, he took out a gun, aimed at the officer and said, “I knew I was wanted, but I dont want to be arrested anyway. Tell Jim Wells I will come to visit him one day." Just at that time, the police officer found himself surrounded by some strong men, gun in hand, pointing to him. Bob then walked into the street and got into a car parking there, followed by those strong men. The car soon disappeared.

另有学生这样写到：

The moment the officer caught Bob by the arm, he got rid of it and ran away at once. He was running down the street as fast as he could, when he was shot on the right shoulder. He turned round. To his great surprise, it was Jim Wells, his o ld friend. He fell on the ground and fainted.

在作文教学中，通过对一定的语言材料进行不同方式的处理，确实是锻炼学生的思维，发展学生的想象力的一条重要途径。当学生对当前的语言材料进行阅读、处理时，进行了充分的分析、比较，又充分展示了自己的想象力，其思维得到了充分的发散。

心理学研究已经证实，发散思维对个体的创造性有着重要影响，我们应该根据教材特点，结合教学内容，注意这种思维能力的训练，并创造一些行之有效的教学技术。可以说，续写结尾、续写故事、改写、扩写等，都是高中英语作文教学中锻炼学生思维，发展学生想象力的有效手段。

Mothers Day Mother’s Day is a holiday when children honor their mothers with

cards, gifts and flowers. In many countries, such as Denmark, Finland, Italy,

Turkey, Australia and the US, people cel lebrate Mother’s Day on the second

Sunday in May while many other countries of the world celebrate their own

Mother’s day at different times through out the year.

One of the best ways to celebrate Mother’s Day is to give your mom the day

off. Let her relax with the rest of the family doing all the housework. Usually,

dad and the kids will let mom sleep late that morning as they go into the

kitchen to prepare her favourite breakfast. Never forget to place a vase with a

single flower on the table beside the food. The kids can pick up the flower from

the garden or buy one from the shop. Arrange everything nicely before mom wakes

up. Some families will carry the food and mom’s favourite sections from the

newspaper to her bedroom so that mom can have breakfast in bed. Presents and

cards from the kids can be handed to mom by themselves or just placed on the

dining table.

After breakfast, go anywhere mom likes to go. Shopping, swimming or going on

a picnic in the garden. Make a special Mother’s Day dinner or take mom out for a

great meal in a famous restaurant she loves most.

Anyway ,let mom enjoy the whole day and feel your love, and then the Mother’s

Day can be a good one. As Mother’s Day is around the corner, it’s time to take

actions!

When I was very small, I was so envious about the adults, because they could do whatever they wanted and did not have to depend on their parents. For me, I did not have money and my parents limited my pocket money, so I couldn’t spend the money to buy whatever I wanted. It seems to me that being an adult is my only wish. Some day, I learned from the movie that being an adult was not that as perfect as I thought.

In the movie, the man struggled to earn money to pay his bills, what’s more, he had to stay away from his family.

Loneliness was always around him. To be independent means we can live our own way and make our own decision. We have more freedom. But at the same time, it also means more annoyance. So why just we enjoy this moment.

在我很小的时候,我很羡慕成年人,因为他们可以做任何他们想做的,不必依赖他们的父母。对我来说,我没有钱,我的父母限制我的零花钱,所以我无法花钱去买所有我想要的。似乎成为一个成年人是我唯一的愿望。有一天,我从这部电影中了解到，作为一个成年人也没有我想象中的那么完美。在电影中,那个人努力挣钱来支付他的账单,更重要的是,他不得不远离他的家人。寂寞总是是围绕着他。独立意味着我们可以有自己的方式生活,做自己的决定。我们有的自由。但与此同时,这也意味着的烦恼。所以为什么不享受这一刻呢。

Water pollution on the impact of industrial and agricultural production of industrial and agricultural production not only need to have enough water, but also have some requirements for water quality. Otherwise, the industrial and agricultural industry will cause great losses, especially in the industrial and agricultural production process using contaminated water, the human has a great harm. First, the destruction of industrial equipment, a serious impact on product quality. Second, the chemical composition of the soil changes, fertility decreased, leading to crop reduction and serious pollution. Third, the city to increase domestic water and industrial water treatment costs.

Clean air is the necessary material basis for people to survive, an adult to breathe an average of 15 cubic meters of air a day, if people breathe heavily polluted air, no doubt harmful to health. 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.

鸟类是和平的象征，我们要爱护鸟类。鸟类既能铺捉害虫，又能美化环境。

一个星期六的下午，我去哥哥家在途中的时候，看见几个人拿着枪在环视四周，不知道他们在干什么，忽然他们拿起枪就朝瞄准的猫头鹰打去，猫头鹰一命呜呼，掉下来被装进了网里，我还看见他们的网里面有其他鸟类，他们得意洋洋，嘴里还说着，今晚又有丰富的晚餐了。我听着非常愤怒，我想：还有成千上万的鸟都有同样的遭遇。有些人为了自己，为了利益，却白白的对鸟下狠手。而鸟类中许许多多的鸟对人类贡献那么大，可还遭人们的捕捉。

燕子是我们人类最重要的益鸟之一，一窝燕子一年要吃掉二十五万只害虫，猫头鹰一年吃掉一千多只田鼠，一只田鼠一年吃掉一公斤粮食，猫头鹰就为人类节约了一千公斤粮食。看似小小的害虫和鸟儿，但小数不怕长计。鸟类对人类做了这么多，却还要遭到人类的捕杀。

鸟类的作用那么大，还是人类的好朋友，我们不应该杀害他们，我们要从小养成爱护鸟类的习惯，鸟类美化环境，帮助庄稼丰收的更多，为什么还要为了自己的利益捕杀它们呢，别因小失大，让我们共同创建美好的家园。

近日的雾霾天气，持续时间之长，范围之大，让我们不得不将环境问题列为重点关注的对象。打赢治理雾霾这样一场攻坚战和持久战，对环境、对人类身体健康，意义非凡。世界卫生组织（WHO）更是列出了世界空气最差的20个城市，可见环境问题的火热程度。环境问题作为重要的社会热点，很有可能在考研英语的作文中命题。据统计，环境问题作为考研英语六大热门写作话题之一，在99、00、09年均有设题（见下表）。今天我们就随都教授一起来学习一下。

一、闪光句型积累

保护和改善生活和生态环境：protect and improve the living environment and the ecological environment

增强环境意识：enhance the awareness of the importance of raise the consciousness about environmental protection

享受国家一级保护：enjoy first-class protection of the State

宣传教育开展保护野生动物：advocate to educate the public the protection of wild animals

帮助减缓全球变暖速度：help slow down the pace of global warming

使用清洁能源：burn clean fuel

加大污染治理力度：strengthen pollution control

崇尚绿色生活方式：pursue a green life

注重节约资源：attach importance to saving resources

削减污物排放：decrease the disposal of pollutants

进一步加快环保规划：further speed up environmental protection plans实行严格机动车排放标准：implement strict vehicle emission standards

二、精彩每日一句

KK教授的每日一句给出了这样一个有关环境的闪光句子，值得考生仔细研究和记忆：As we all know, our country has been under growing pressure to address the causes of air pollution as the PM2.5, a key indicator of air pollution, increasingly hits the new record and even smog frequently smothers the countrys large cities.

【参考译文】如我们所知，我国正面临着越来越大的解决空气污染的压力，因为PM2.5（空气污染的主要指标）不断的刷新纪录，雾霾甚至窒息了我国的主要城市。

三、PM2.5知识拓展：

严重的雾霾，让PM2.5这个数字飞入了寻常百姓家，下面我们一起来了解一下，以便积累考研英语作文的写作素材。

PM2.5的“PM”，是英语“particulate matter”的缩写，意为“细颗粒物”。大家在

家中都看到过这样的现象：一缕阳光射入屋内，光柱中有无数微尘在翻飞，这些微尘就是PM50和大于PM50的颗粒物。桌面上，落了一层灰，那是远远大于PM50的颗粒物。所以PM2.5是无法被肉眼看到的。但其虽小却具有极大危害。PM2.5携带了许多有害的有机和无机分子，是致病之源。细菌是人所共知的致病之源，PM2.5和细菌有得一比。能引发呼吸道阻塞或炎症，使得致病微生物、化学污染物、油烟等“搭车”进入体内致癌，影响胎儿发育造成缺陷，还能通过气血交换进入血管。

通过今天的学习，相信各位考生都积累了不少写作素材。的确，考研英语的写作题型是对考生英语综合能力的考察，同时，由于题目一般接近社会生活热点，所以考生在平日综合素质的积累也在一定程度上帮助考生获得高分。时间所剩不多，各位抓紧！预祝各位考生取得自己理想的成绩！

考研成功难又不难，一旦大家开始准备就要全力以赴。自制力差的学生可以找几个研友，互相激励，因为坚持下来也确实不容易，也看个人习惯，有的同学可能一个人学习更有效率；在这个过程中更主要的还有大家坚持的信念，坚持完成一件事情本身就是成功。

在三百多天的日子里，老师会一直陪伴着大家，里边的每条微博、微信、咨询都是温暖大家并激励大家前行的动力。奔跑吧，2016的考生们！

虽然有突破口、也有规律可循，但这并不意味着我们可以一劳永逸、高枕无忧，要知道，想要精通世界上任何一门语言，除非有天生的语言天分，否则偷不得半分懒，只能勤勤恳恳反复练习。一遍不懂读两遍，默念不行就大声念出来，遇到不认识的单词就查，不懂的句子就静下心来拆分结构。总之，读书百遍、其义自现，英语学习之路上没有笨蛋，只有懒人。 综上就是小编给大家提供的高分技巧，技巧就是牢固的知识点和强悍的答题思路，预祝所有考生2016考研有个好成绩。

小提示：目前本科生就业市场竞争激烈，就业主体是研究生，在如今考研竞争日

渐激烈的情况下，我们想要不在考研大军中变成分母，我们需要：早开始+好计划+正确的复习思路+好的辅导班（如果经济条件允许的情况下）。20xx考研开始准备复习啦，早起的鸟儿有虫吃，一分耕耘一分收获。加油！

As soon as everyone steps into junior middle schools, English plays an important role in our daily life. Whats more, with China entering the WTO, English has become the most popular foreign language in China. As a student, I think everyone should have a good knowledge of English. However, nowadays the majority of students have great difficulty in learning English. How does the problem come about? For me, I am into English. In my opinion, the reason is that a great many students have no interest and confidence in learning English.

So, I think it is important to develop an interest in English and to remember that patience is the key to learning English. Then try your best and take every chance to communicate with others in English. Besides, by listening to English tapes you may make great progress. I suggest buying some English magazines and newspapers, such as English Weekly, the best among them, which will help you a lot.

Do as I have said above, you will be successful sooner or later.

首先，我先给大家讲一个真实的事件。那是我随我的外公从宜昌坐船前往三峡时发生的一件事。

那天早晨，船上的人都起来了，正准备打水洗淑。可是船上的水龙头半天也只下来几滴水，一询问，原来是船上的水用完了！所以，大家只有排着长长的队伍，慢慢的等。我望着船下，船下虽然有着流不尽的江水，但却没有一个人愿意来使用它。因为江水太脏了，是那么的浑黄，又有谁敢去使用呢？只有慢慢的排队，慢慢的等！

如今科技虽然在高速发展，但这影响到了我们的环境。河流污染，大气污染，树木的减少，沙漠的增多……这一切的一切都是拜人类所赐！国家虽然在重视，世界虽然在重视，什么环境保护日，这些事又有多少人影起了注意呢？在我看来，是极少的。国家虽然在这么说，可是光说不做又有什么用呢？做了也只是少数罢了！根本没有从主要原因抓起！你看，黄河的水不是还在被污染吗？工厂不照样还在污染大气吗？抓，就应该从小抓起，从人们的素质，品质抓起，可是国家乃至世界这么做了吗？没有！即使做了也只是做样子罢了。环境不是照样还在被污染吗？

动物还在灭绝，山洪还在爆发，沙尘暴照样存在……这都充分说明了环境还在污染！国家只会去赈灾，而不去根本抓起，只会去赈灾，这又有什么用呢？各种灾难不还是照样在发生吗？我们应该像鲁迅一样。他当初从医是为了拯救中国人，而他发现，这解决不了根本，所以，他当了作家，去拯救人们的精神。因为这就是根本！所以，我们作为21世纪的小主人，就应该明白，什么是破坏环境的根本，从要点去解决它。努力吧――21世纪的我们

On October 6th, 2013, I went Xiao Meisha with my fellows to spend a nice seaside holiday. On our arriving at Xiao Meisha, we were all filled with excitement, since this was our first trip to the seaside. Xiao Meisha was an excellent seaside resort indeed. There the sky was clean and bright, the wind was mild and pleasant, the sandy beach was soft and comfortable, and the sea was so magnificent. We felt refreshed at that moment. It seemed as if we traveled in the heaven.

We did many kinds of activities at the seaside. Some of us went swimming in the sea; some went surfing; some dived underwater; some had a walk along the sea; some played sports on the beach. But I just took some photos of the beautiful sea scenery. All of us had a happy time.

In the evening, when it was about the time for leaving, we were unwilling to go, because the beautiful sea scenery deeply attracted us. We all expected for our next coming. So I could say that the seaside holiday was both relaxing and wonderful.

In the last several decades, our earth has been extremely polluted, such as

air pollution, water pollution, noise pollution and so on. In recent years, the

extreme weather becomes more and more frequent. Winter gets colder and summer

becomes hotter and it rains more frequently. All of these warn us that

protecting the environment is a serious and emergent event. As our general

people, we should build proper lifestyle. We should pay attention to water and

light saving. When we go out, we should firstly choose the public

transportation. The most important is that we must realize that we can do a lot

of things to protect our environment. Its our duty to make our home better.

Let’s change from ourselves.

people have been living on the earth for thousands of years.humanactivity influences the earth. some people believe that theearth isbeing harmed by human activity. others feel that humanactivitymakes the earth a better place to live. in my opinion, theearth isbeing damaged by human activity. there are manystatementssupporting my opinion.

human activity has damaged natural environment and almostexaustednatural resources. modern industry needs more and moreresources,including minerals, fuels and water. so we confront ofthe seriousproblems such as the lack of fuels and water.ecological balance isdamaged because factories occupy many placeswhere animals andplants live. more and more buildings areconstructed and forestsbecome less and less. if we cannotrecognize these problems andsolve them soon, we would finally losethe environment suitable forour living.an other serious problem is the green-house effect.humanactivity decreases forests and increases the usage of fuels sothatthe gas of carbon dioxide is output more and more and there arenotenough plants to absorb it. the green-house effect is moreobviousand more sensible these years. due to the effect, icebergsin thesouth polar and north polar melt and the sea level becomeshigherthan before. i am worried about the cities nearby the sea andhopescientists find an effective method to eliminate thegreen-houseeffect.

although we have advanced machines and our life seemsmorecomfortable than before, we have less chances to approachnaturesand less spaces to act. the cities become bigger and if wewant tohave a picnic with our friends, we have to drive a longdistance tofind a natural place. in fact, the spaces of humanactivity arebeing damaged by the skyscrapers and factories.from the above statements, we can conclude that humanactivitybrings the earth many damages. fortunately people haverecognizedthe point and i believe that the earth will become abetter placeto live with our ceaseless efforts.

走过一条条小路，路过一条条小河，经常会看到一些垃圾，如：被吃过的水果的果皮、零食包装、塑料瓶子等，工厂和汽车放出的气体，使到处变得乌烟瘴气。大家都想知道是谁在破坏，现在揭晓答案：“是我们，人类！”

目前世界上百分之六十的地区街上都会出现有垃圾的现象，只有少数的国家有一尘不染的“美誉”，比如说：日本，日本的大街上几乎没有垃圾桶，有的话也是规定了倒垃圾的时间，其余时间不能倒垃圾，他们一般在要逛街的情况下，都会随身带个垃圾袋，以免买了东西的袋子或是遇到突发情况都不用丢脸地找别人借袋子，他们都不会像我们国家的有些人那样自私，他们每个人都有一个共同的信念：保持清洁卫生，不能让其他国家的人决得日本的卫生习惯很差！

有一种污染名叫白色垃圾，我简单介绍一下：塑料制品作为质轻，防水，防腐蚀的新型材料，在全世界被广泛运用。

塑料最早运用于农业地膜，给农业生产带来了极大的发展，可使农作物在任何季节生长，促进了市场消费。据市场统计，自1990～1995年，塑料的生产以每年8．9％的速度增长，已经席卷了整个地球。简直可以称作“白色革命”。但它在为人们提供方便的同时，也给人们带来了一场“白色灾难”。

至今，“白色污染”已经成为众所周知的一个新型名词。它主要指各种发泡塑料袋，农用地膜等给环境造成了污染，并且得到社会的普遍关注。

还有人做过统计，火灾中被浓烟熏死呛死的人是烧死者的4？5倍。在一些火灾中，被"烧死"的人实际上是先烟气中毒窒息死亡之后又遭火烧的。

浓烟致人死亡的主要原因是一氧化碳中毒。在一氧化碳浓度达1。3%的空气中，人吸上两三口气就会失去知觉，呼吸1？3分钟就会导致死亡。而常用的建筑材料燃烧时所产生的烟气中，一氧化碳的含量高达2。5%。此外，火灾中的烟气里还含有大量的二氧化碳。在通常的情况下，二氧化碳在空气中约占0。06%，当其浓度达到2%时，人就会感到呼吸困难，达到6%？7%时，人就会窒息死亡。另外还有一些材料，如聚氯乙烯、尼龙、羊毛、丝绸等纤维类物品燃烧时能产生剧毒气体，对人的威胁更大。

所以，我想提醒大家：“千万不要破坏环境，害人害己，而且对自己的身体没有好处！”

Today the quality of our natural environment has become an important issue. The world population is rising so quickly that the world has become too crowded.

We are using up our natural resources and at the same time polluting our environment with dangerous chemicals. If we continue to do this, life on earth cannot survive.

Concerned people have made some progress in environmental protection. Governments of many countries have established laws to protect the air, forests and sea resources and to stop environmental pollution.

Still more measures should be taken to solve environmental problems.

We are sure that we can have a better and cleaner place in the future.
