Secondly， I11 say something about the tradition on Mid-Autumn Day。 Look!Theres a big tree in a garden of a Chinese fami-ly。 All the family members are sitting around a big table under the tree in the open air。 They are eating the mooncakes and admiring the full moon in the sky。 That is a family reunion dinner。 The mooncakes and the moon represent the love from a family。 I think this is one of the most valuable things in the world。

October 1st is the national day of our country, which is a public holiday for the whole country. It’s an important day that marks the beginning of PRC. On that day, there are plenty of celebrations holding throughout the country, from the central government to the general people. And public places, including big squares, parks are decorated in festive theme. In recent years, the national holiday means the golden week as well, which is a short holiday that all people expect to. With the improvement of living standards, people have more money and desire to travel and the golden week is a good chance for them. Besides, for those people who would not go out, it’s a good time to have a good rest as well. Therefore, the national day means a lot to the Chinese.

10月1日是我国的国庆节,这对于整个国家是一个公共假日。这是一个重要的日子,标志着中华人民共和国开始。在那一天,有很多庆祝控股全国,从中央政府到一般人。和公共场所,包括大广场,公园在节日的装饰主题。近年来,国家节日意味着黄金周,这是一个短暂的假期,所有的人都期待。随着生活水平的提高,人们有更多的钱和渴望旅游黄金周是一个很好的机会。除此之外,对于那些人不出去,这是一个很好的时间来好好休息一下。因此,中国的国庆节意味着很多。

春节到，真热闹，穿新衣，戴新帽。家家户户放鞭炮”。这是描写过新年的一首老诗。20xx年的春节即将来临。市政府发出通告：“越城区二环以内禁止销售燃放烟花爆竹。”看到这个标题时我心中曾经产生过疑问：为什么不能燃放烟花爆竹呢?烟花升到空中，五颜六色的样子多漂亮啊。爆竹声声也可以增添节日欢乐的气氛。通过学习，我明白了烟花爆竹燃放后可以导致严重的空气污染，噪音污染和火灾隐患。空气污染和噪音污染可以影响绍兴的生态环境，给人们的身体健康带来危害，火灾会使国家和人民的财产遭受损失。

然而，禁止燃放烟花爆竹的执行情况并不令人乐观，半夜里，爆竹响声阵阵，小区里结婚，酒店里孩子办满月酒，都要燃放烟花爆竹来庆贺。

政府发出的禁令，我们需要严格遵守。但禁令屡屡被当作耳边风，却无人受到惩罚，这样一来，就会有更多的人效仿，管理就会难上加难。因此，对于有禁不止者，政府应加大监督和处罚力度，更重要的是，每一个人必须从自我做起，自觉遵守政府禁令。我们必须意识到，燃放烟花爆竹是不折不扣的自杀行为。

作为一名小学生，不仅要带头遵守政府禁令，还要向家长、邻居和周围居民作好宣传工作，让我们在清新、和谐的环境里过一个祥和的春节。

Green environmental protection is to make us live a happy life in a clean

environment, however, the environment around us in a worse if we dont alarm,

starts from me. My dad used to drive his car to work, listen to my advice, to

poor-house. The setting sun is reflected from the windows of the alms-house as

brightly as from the rich mans abode; the snow melts before its door as early

in the spring. I do not see but a quiet mind may live as contentedly there, and

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 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 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, 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.

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 we get along well with it. Only by saving the environment can we save ourselves. 保护环境初三英语作文（二）

Therefore, We need some countermeasures from the viewpoint to prevent the city environment form disaster and to manage environmental risks.

Pollution has been a serious problem for a certain time around the world. There are many causes for it. Transportation is the main factor of pollution. When the waste gas from cars is released, the air is polluted. People breathing in the polluted air can develop respiratory disease. Another factor is that people throw their garbage everywhere. All kinds of garbage not only spoil the splendid environment, but also cause environmental pollution. Whats more, industrial pollution also deserves our attention. Wastewater from factories is poured into rivers and this causes water pollution. As a consequence, the greenhouse effect becomes a problem which needs our immediate caution and how to solve is urgent all over the world. At present, some measures have been taken to prevernt.

For example, people classify the garbage and some is recycled after being collected. People are also encouraged to use paper products instead of plastic products because we know that our living condition will be worse if we keep ignoring this problem. And I believe we can prevent pollution if everyone makes the efforts.

Protection of EnvironmentThere are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.

To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most 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.

There are two main causes for cancer: heredity and environment. We can do nothing to change our heredity, that is, the basic physical characteristics that arepassed on to us by our parents. However, we can do a great deal to control our environment, which may account for eighty to ninety percent of all cancers.

Enviromnental pollution can be divided into two kinds: personal and impersonal. Personal pollution may be defined roughly as unhealthy habits such as smoking, drinking, and eating the wrong foods. Clearly, with enough will power we can control this personal environment.

Impersonal pollution, on the other hand, refers to those things which are beyond our individual control. One example would be indus trial pollution, which is very hard to control because of the expenses that are needed. The American automobile industry, for example, resisted the law requiring smog-control devices because il feared the added expense would reduce profits. Nevertheless, some laws protecting the environment have been quite successful in reducing pollution.

For me, physical recreation is necessary for good health but intellectual pursuits such as reading stories provide the most pleasure.

The generation gap refers to the difference in attitude toward thing or the

lack of understanding between young people and older folks.

In families as well as in society, the young and the older may not agree

with each other on this and that from time to time. Young people would llke to

make as much money as they could and spend as much money as they could earn

while older folks are easily satisfied with what they earn and save as much as

possible. Young people llke the exciting and deafening pop music while older

folks prefer melodious folk-songs or classic music. A boy and a glrl today may

fall in love with each other as quick as lightning, while their parents or grand

parents might trudge over a long distance before they kissed each other and

became lovers when they were young.

However, we should not be amazed at the generation gap,for it is quite

natural in the development of society. The world is a changing world, in which

everything keeps changing, generations of human beings included. And changes

lead to progress.

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
