Private cars have become an important aspect of people’s life in many parts of our country,especially in large cities such as Beijing,Shanghai and Guangzhou.While they bring much convenience to people,they are also widely criticized.

There are some arguments for owning private cars.In the first place,cars allow people to move around freely,whichgreatly improves our living standard.We easily drive cars for traveling.In second place,When we have something urgent to do,cars are quick than other vehicles in some extent.Last but not least,the car industry can boost economy by creating many job opportunities.

However,there are also many arguments against cars.First of all,they pollute the environment by emitting harmful gases.What’s more,cars cause a large number of traffic accidents,which bring great misery to their family.

As far as I am concerned,we should limit the number of private cars by providing better mass transportation and better service for the people.Everyone should sacrifice his or her own interest for the mass society.

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.

Pollution: An Increasing Concern in China It is reported that ten big cities in China are being ranked among the top twenty cities with the highest pollution index in the world. This means it is high time we did something to bring the situation under control.Many factors are contributing to the deteriorating situation: industrial wastes pumped into the air, the lakes and rivers; a increasing number of automobiles crowding into the streets; the widespread use of plastic bags etc. To my view, stiffer laws and regulations must be implemented to check pollution. Industries that release wastes without permission should be heavily fined. Cars should be equipped to minimize the exhaust they release into the air. And the use of plastic bags and disposable meal boxes should be banned. Whats more, the media should play an important role in implanting a sense of environmental consciousness into peoples mind. If everybody works toward a common goal of making the environment better, we can create a cleaner and lovelier world for us and for the coming generation.

With the remarkable improvement of people’s living standard, people tend to buy more goods. As a result, a plenty of plastic bags are threw around and caused white pollution. Not only does it do harm to the environment, but also give people the impression that the city is dirty. As we all known, plastic bags are non-biodegradable material and it will stay in the soil for a long time. What’s worse, the poison released from the plastic bags is harmful.

随着人民生活水平的显著提高，人们购买的商品越来越多。所以，到处都是塑料袋，造成白色污染。塑料袋不仅污染环境，也给人城市很脏的印象。众所周知，塑料袋是不可生物降解的材料，会长期留在土壤里面。更糟糕的是，从塑料袋中释放的有毒物质是有害的。

Being current generation of young people, we should take measures to control the use of plastic bags .We can substitute them with cloth bags or reuse them. And the government can make rules to avoid using them. If we do our best, the use of plastic bags can be reduced, thus the white pollution can be controlled.

作为当代年轻的一代，我们应该采取措施来控制塑料袋的使用。我们可以用布袋来替代塑料袋或者重复使用。政府也可以制定规定来避免使用塑料袋。如果我们努力做好，塑料袋的使用就可以减少了，从而白色污染也会得到控制。

In fact, there are many things that can seriously pollute the environment: litter, spitting, grass and so on. The consequences are severe. But the waste of resources cannot be ignored. The worst is the waste of water.

At present, the reform and development of our country is at a critical juncture, and we should strive to achieve the goal of building a moderately prosperous society in all respects. But there are still some problems -- our living environment is seriously polluted; And the green resources are falling.

We do a lot of what the environment, such as: on one occasion, in a clean small garden, there have been some rubbish, gradually where there are a lot of people throw garbage, there is a garbage dump. It turned out that the trees were green and the flowers and grass were blooming. The bees and the butterflies were there, and there was a smell of enchantment. But now, there was nothing to do with it, and the smell of it was so bad that no one was willing to stay there any longer. Alas! It is a pity that such a beautiful garden is gone. If people notice that they dont pollute the environment, now, by the way, its a kind of escape. And, what a wonderful thing for people to have a rest and take advantage of the cold. But now its a junkyard, and the consequences of polluting the environment are terrible.

And there are a lot of factory waste is also pollute the environment, but the most serious is the pollution of water, I heard of such a story: there was a village, there was a clear pool. There were lotus flowers in the water and the goldfish, and it was so beautiful that visitors to the village would not forget to take a look at the scene. And people in the village wash and cook and drink water and water, so the water is very precious. One day, a businessman opened a factory near the pond, and the factory shut down a lot of waste water and garbage and went into the pond... The result can be imagined: the goldfish died, the water side became the sewage, the tourists no longer came, the people in the village moved away... Alas! The little pond has disappeared. The factory severely polluted the environment and made the environment in the village very bad and affected peoples lives. Its a story, but there are a lot of these things in everyday life, and the results are very serious, not just simple consequences.

In fact, there are many things that can seriously pollute the environment: litter, spitting, grass and so on. The consequences are severe. But the waste of resources cannot be ignored. The worst is the waste of water.

Now, Beijing is a city of severe water shortages, but there are a lot of people in the waste water, such as: there are a lot of people out of the water to wash the dishes and laundry water and reuse. In fact, although can only save a little water, economy is a lot of!

Also, people who sell fish in the market love to put a faucet on the side of the water, and when they use water, they will let the water flow freely. How much water they would waste if they went on like this!

The drink, the wine, etc., are now made with water. Some factories use a lot of water, so some of the water is wasted. Thats a lot of wasted water. This water can do a lot if you save it! You can also avoid a little water.

先如今环保已经成为了我们必做的事，因为现在地球上的环境正受到威胁。

现在，我们知道地球已经开始变暖，寒冷地方的冰已经开始融化，变成的水使水平面越来越高，让许多沿海的国家被淹没。更多的土地沙漠化，天灾不断来袭，使我们的生活不再那么无忧无虑。

首先，我们必须从身边做起。

大片森林被不断砍伐，汽车尾气不断排放……这些首先就会直接影响到我们的生活，因为这些让我们“不敢呼吸”。所以，这些问题最好的解决方法就是少开车，多骑自行车，而且，骑自行车也很有益身体健康!。可虽然一直这样说，而且说了也不只一次，可为什么还是有那么多的车在路上呢?所以，这个方法实在，有点不实用。

最简单的就是种树了，树是人类的好朋友，他们能帮助人类许多事，比如净化空气啦，等等。所以，多种树，这个方法很实用!

总而言之，我们的地球要我们自己去爱护，去保护，要用实际行动来帮助地球，让环境更美好!

同学们，我们现在的生活过得是越来越好了，几乎所有的人们都过上了幸福快乐的生活，人们安居乐业。

但是，当你有一天行走在宽阔的道路上，欣赏着旁边的緑树红花，突然闻到扑鼻而来的是污水的臭味时，你不觉得恶心吗?当你心情无比舒畅的走在干净的校园里，突然一个塑料袋飞到你的脸上，你不觉得扫兴吗?相信同学们也有同感。人类和动物的生存环境已经受到严重的破坏。使许多珍贵的动物面临灭绝的危机。所以保护我们唯一的地球，保护我们的家园，是我们这一代青少年的责任。

我真想对那些破坏环境的人大声的说一句：“请停下你们的行为。”虽然我个人的“力量”很弱小，但是我可以号召所有的同学们一起和破坏环境的人做“斗争”，来净化我们的家园。还人类和动物一片干净的蓝天。让小朋友们在阳光下茁壮成长，让鸟儿们在天空中自由飞翔。

在这里，我再一次号召同学们从个人做起，从我做起，不要乱扔垃圾，不随地吐痰，爱护花草树木，节约用水用电。坚决和破坏环境的人做“斗争”做一个环保“小勇士”。

Our beautiful earth is only one, is also the only one. If you dont cherish, in the end, the only regret. But now, people regardless of the image, the damage to the environment.

In the street, always see someone to walk less, will their garbage on the ground, this kind of behavior is damage to the environment, and not beautiful.

When your foot jump on it, when enjoying the care of the earth, you can know it in complains to heaven. The grass also hurts, it just didnt express. Dew on the grass face every morning there will be some, and the dew like their tears. The grass also have feelings, when it is happy, it will be a purposeful, enjoy the warmth of sunshine, the breeze bath; When it cry, it will be bent her waist; When it is complained that their is a humble grass, it dead. Lets ensure that their feet, dont trample on the lawn. Use action to soothe the soul of the dead, renewed the miracle of life.

Have you seen? Dozens of people saw an axe in hand, they are going to cut down trees. When forests there saw, with the trees fall. When there is a tornado and sandstorms, no trees to shelter from the rain. Then there is no regret medicine to eat. Without trees, also become no longer pure and fresh air.

Friends, protect our environment, is to protect our earth. Cherish our only the earth, is to cherish our life. When a rainbow sky, means that garbage to go home, the grass smiles, uncle grandpa happy, our earth mother without crying.

参考翻译：

我们美丽的地球只有一个，也是唯一的一个。如果不好好珍惜，到头来，只有后悔。可现在，总有人不顾形象，在破坏环境。

在街上，总会看见有人为了少走几步路，将自己手中的垃圾随意扔在地上，这种行为既破坏环境，又不美观。虽然有惩罚，但一直以来并没有什么成效。到最后，只有清洁工来收拾残局。那假如是在自己的家里，到处都是垃圾、苍蝇还满天飞，你自己好过吗?那假如世界上没有清洁工，要是这样下去你敢想象吗?看着人们这样的行为，地球妈妈哭泣了。让我们管好自己的手，不管是在什么地方，什么时间，请将自己手中的垃圾送回家。

还有一种不好的行为，那就是践踏草坪。每当放学，有些孩子为了开心，总喜欢在草地上踢足球。当你的脚踏在上面蹦蹦跳跳的时候，享受大地关怀的时候，你可知道它在埋怨上天。小草也会疼，它只不过没有表达出来而已。每天早上小草脸上会有一些露珠，而这些露珠就像是它们的眼泪。小草也有感情，当它快乐的时候，它会挺直腰，享受阳光的温暖，微风的沐浴;当它哭泣的时候，它会弯下自己的腰;当它埋怨自己是颗不起眼的小草时，它已死去。让我们管好自己的脚，别再践踏草坪。用行动安抚已死去的灵魂，再度点燃生命的奇迹。

你看见过吗?几十个人的手里拿着电锯斧头，他们是要去砍伐树木。当森林出现电锯声时，将伴随着一棵棵树的倒下。当出现龙卷风和沙尘暴时，再也没有树木来挡风遮雨。到时再也没有后悔药可吃。没有了树，空气也变得不再清新。当你冷的时候，你去捡树木生火，可你的温暖却是牺牲一棵树换来的。有些树木生长了几百年甚至几千年，可就一把不起眼的斧头结束了它漫长的生命。多么坚强的树，不知当它倒下的那一瞬间，它想到了什么?多么顽强的树，可最终还是逃不过厄运的毒手。

朋友们，保护我们的环境，就是保护我们的地球。珍惜我们唯一的地球，就是珍惜我们的生命。当天空出现彩虹时，就说明垃圾回家了，小草笑了，大叔爷爷乐了，我们的地球妈妈没有在哭泣了。

When we are in our classroom after 8：30 in the morning，we should not keep the lights on to avoid wasting electricity since there is enough light in the classroom.And if it is cloudy and rainy and lights are on，we should turn off the lights after school.Another thing we can do is to protect the forest which is reducing.We should use both sides of paper and we should not use paper cups and disposable chopsticks which are made of trees.

All these are the things we can do every day to make our environment better. As long as we insist on doing so，our environment will become better and better.

范文二

The environment has been polluted badly today and the nature punishes the

human being by all kinds of disasters, such as the heavy haze in Beijing, which

damages people’s health. World Environment Day is on June 5th. It pays attention

to call for the public to make an effort to bring the world a clean

environment.

Look at the pollution around us, which exists everywhere. The cars release

the gas which pollutes the air and the rubbish can be found in every corner of

the street. All of these daily incidents hurts the world we live. Especially the

factories, they release the heavy smoke and make the sky becomes dark. What’s

more, the wasted water flows to the clean river.

Though the government has made some action to punish the businessmen for

releasing the polluted sources, they still dare to take the risk of earning the

biggest profit. If we hurt the environment, it will hurt ourselves, because we

live together. The polluted environment threatens our health. If we want to live

the comfortable life, then the only way is to be nice to the environment.

It is very important to deal with the rubbish in cities. Rubbish must be thrown away or reused properly. Or it may cause a lot of problems. It may pollute the air and water. People may get ill when they breathe the polluted air or drink the polluted water.

Our city has started to face the problem. Some rubbish is sorted and sent to a certain place .Waste gas is cleaned before it goes into the air. Waste water is also cleaned before it is poured into rivers.

People should be prevented from throwing rubbish everywhere. We should try our best to take care of our environment and fight against pollution.

这是处理城市垃圾非常重要。垃圾必须扔掉或者重用。或者它可能会导致很多问题。它可能会污染空气和水。人可能生病时呼吸受污染的空气或饮用受污染的水。

我们的城市已经开始面临的问题。一些垃圾分类并送到某个地方。废气进入空气之前清洗。废水也在它倒入河流清洁。

人们应该阻止到处扔垃圾。我们应该尽我们最大的努力去保护我们的环境，与污染作斗争。

Depending on personal experience, personality type and emotional concern, we find that some people hold the idea of living in the country, while others prefer living in the city. In my opinion, I prefer the city life, though it has advantages and disadvantages.

First of all, city life is very colorful. City is the center of the surrounding area. So, it is also the most booming place having the best things. There are many great things and wonderful activities in the city, while there isn’t in the country. For example, there are KFC, wonderful shopping mall, delicious food from various places, dancing club, different kinds of activities and so on. We can also learn the culture from all the countries. Despite city life is so wonderful, it still has many disadvantages. Nowadays, with the improvement of people’s living standard, people have more cars and more people come to city, and then the city becomes more and more crowd. As a result, traffic jam emerges, which makes great inconvenience for people to go out. What’s worse, the air pollution becomes serious day by day, which is bad for people’s health.

To sum up, every coin has two sides. Living in the city also has good side and bad aspect. Whether like living in city or not depends on individual thinking. As myself, I like living in city though I know the disadvantage of living in city.

“我不喜欢弟弟或妹妹，因为那样爸爸妈妈就不会再爱我……”最近上网总能看到类似于二胎这样的话题。这个政策是去年新颁布的，瞬间引起了社会各界的更关注，它已成为我们备考高考作文的话题之一。

此政策在网络和微信上引发了热议(become a sensation on the Internet and We Chat)。不少网友认为"00后"(children born after 2000)太自私，即使是同意父母生二胎的孩子，在有了弟弟妹妹后脾气也会变坏。但也有不少人认为，这仅仅是教育方式的问题而已(the problem lies in education)。如青岛一所小学的一群四年级学生日前成立了"反弟弟妹妹联盟"，说服父母不要生二胎。(A group of fourth-graders at an elementary school in Qingdao formed an "anti-siblings alliance" in an effort to persuade their parents not to have a second child.)该校一名老师最近发现，班里有八个孩子常聚在一起窃窃私语，讨论这件事(hold secret meetings to discuss the issue)。这些学生担心弟弟妹妹会分走自己独享的父母宠爱(steal their parents exclusive love)。

有话题就会有相关词汇，这就要求大家在平常的学习中多多积累，这样到用了时候心中自然就有丘壑。同时也可以扩充相关词汇，如：流动人口mobile population;独生子女家庭only child family;生育时间表birth time schedule;备孕plan for pregnancy。

二胎政策实施过程中，也给社会带来了一定的影响。这一部分探讨也可以作为作文的写作素材。如全面二孩政策(universal two-child policy)出台后，中国内地主要城市三居室或四居室的大户型房子(large three or four-bedroom homes)销量攀升。北京和上海等城市的很多夫妇正在搜寻居住环境更佳的大房子(hunt for larger homes with a better environment)，为家里添丁加口早做准备。据估计，新的生育政策将使未来5年内多增加1700万新生儿(extra 17m babies being born within the next five years)。

我提出了以下几点见意。

一、开展“保护环境，人人有责”的活动，让每个同学都行动起来，不要踩踏花草，不要随便攀折树木。

二、让大家都把垃圾扔进垃圾箱，不要随地乱扔。要让有限的资源，无限的循环。

三、不要随地吐痰。痰是有许多细菌的，不要把自己的病菌带给他人。

四、在校园的每一个地方都贴上保护环境的标语。让同学们时时刻刻地记住这些标语。为了我们美好的校园，请记住“校园是我们的家园”，保护环境不是一个人就能做到的。自只有大家齐心努力，才能使校园更美丽。让我们行动起来吧！共创一片美好的校园吧！

presently, the world is faced with serious water problems. but these problems witt become more intense and more comple in the future. our increasing population witt tremendously increase urban waters, primarily sewage. on the other hand, increasing demands for water witt decrease substantially the amount of water available for diluting wastes.

rapidly epanding industries which involve more and more comple chemical processes will produce large volumes of liquid wastes. many of thesewitt contain chemicals that are poisonous. to feed our rapidly epanding population, agriculture will have to be intensified.

this will involve ever increasing quantities of agriculture chemicals. from this, it is apparent that drastic steps must be taken immediately to develop corrective measures for the pollution problems.

there are two ways by which these pollution problems can be lessened. the first relates to the treatment of wastes to decrease their pollution hazard. this involves the processing of solid wastes "prior to" disposal and the treatment of liquid wastes to permit the reuse to the water or best reduce pollution upon final disposal.

the second approach is to develop an economic use for all or part of the wastes. farm manure is spread in fields as a nutrient. wastes from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained.

liquid wastes from other processing plants may also be used as a supplemental source of water. only by doing these promptly now can we epect to solve the serious water problems in the future.
