Should We Help Strangers?

Recently our class had a discussion about whether we should help

strangers.Different students have different opinions.

Some think we should try to help strangers. Helping others is a virtue，and

helping others is helping ourselves.We may come across some trouble and need

others help some day.If everyone isnt willing to help us just because we are

strangers to them，its hard to imagine what our world will be like.

However，some are afraid that helping others can sometimes bring us

trouble.Sometimes we are just misunderstood and even have to pay the cost of

kindness.

In my opinion，we should try our best to help others when they are in need

of help，but we should also protect ourselves from getting into trouble.If

everyone tries a little kindness，our world will be full of love.

Throughout history man has changed his physical environment in order to

improve his way of life。 With the tools of technology he has altered many

physical features of the earth。 He has transformed woodlands and prairies into

farms and made lakes and reserviors out of rivers for irrigation purposes or

hydroelectric power。 Man has also modified the face of the earth by draining

marshes and cutting through mountains to build roads and railways。

However， mans changes to the physical environment have not always had

beneficial results。 Today， pollution of the air and water is an increasing

danger to the health of the planet。 Each day thousands of tons of gases e out of

the exhausts of motor vehicles。 Smoke from factories pollutes the air of

industrialized areas and the surrounding areas of the countryside。 The pollution

of water is equally harmful。 The whole ecological balance of the sea is being

changed and industrial wastes have already made many rivers lifeless。

Now environmental protection is more pressing than ever before。 As we know，

massive destruction of environment has brought about negative effects and even

poses a great threat to mans existence。 Indifference to these problems will

mean mitting suicide。 Therefore， effective measures should be taken and laws

passed to conserve environment。 Otherwise，man is certain to suffer from the

serious consequences caused by this lack of care for his living

surroundings。

Directions:For this part， you are allowed 30 minutes to write a composition on the topic:

Pollution: An Increasing Concern in China You should write at least120 words following the outline below in Chinese.

1. 中国的污染的现状

2. 造成污染的原因

3. 解决的办法

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. What’s more， the media should play an important role in implanting a sense of environmental consciousness into people’s 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.

环境污染的作文一

本周末西安有严重的沙尘暴天气，整个天空都是昏沉沉的，空气中有很重的土味，我出门的时候带着口罩。我看见地上，花坛里，电梯间里都有一层黄土，有很多人都咳嗽。妈妈说这个季节一定要多吃新鲜水果和蔬菜，保证合理的休息时间，身体才会好。

真希望这种天气早点结束，我就可以下楼骑自行车了。 环境污染的作文二

这两天西安有大雾，昨天晚上看电视上说西安的空气质量很差，已经连续两天在全国排名最后了。

妈妈说大雾是由于空气中的灰尘太多了，吸入这些灰尘，人很容易生病。现在很多人出门都要开车，汽车尾气对空气污染很大，我们走在大街上，都能闻到刺鼻的气味。还有很多工厂的烟囱，经常冒着黑烟。我觉得我们要爱护环境，因为环境不好，对大家都是伤害。 环境污染的作文三

地球失去了以前的美好风景，城市的空气在渐渐的被污染，那些污染产品我以后是不会用他们的。我想叫世界变得更美好，以前的空气很干净，大海以前的水都是很清新的，祖国是我们的家，我要爱护祖国，祖国的海洋也是各种鱼类的家，也是水母和鲨鱼的家。

森林是动物的家，也是蝴蝶的家，我也要爱护树木，保护环境。为了祖国我要付出一切代价。 环境污染的作文四

一个阳光明媚的早晨，没头脑和不高兴在小区里散步。走着走着，他们看见一个小朋友把吃零食的包装纸随手一扔，就走了，没头脑看见了马上捡起包装扔进了垃圾桶里，不高兴说：“这又不是你扔的，干嘛多管嫌事?”没头脑说：“小区是大家的，做一些力所能及的好事有什么不好?”

他们继续往前走，又看见一位阿姨觉得小区里的花很香，正想准备摘一朵带回家呢!这时，没头脑一个箭步冲上前去，笑着对那位阿姨说：“阿姨，小区里的花真漂亮呀!要是你把它摘了，它就会枯萎，那可就不好看了。”阿姨听了，笑着对没头脑说：“小朋友，谢谢你!要不然我可就把这么美丽芬芳的花给毁了。”这时，不高兴气喘吁吁地跑过来，对没头脑说：“没头脑，我一定要向你学习，做一个环保小卫士。”“好啊!”没头脑爽快地答应了。

没过多久，小区变得干净了，这可都是没头脑和不高兴的功劳，因此小区里的市民都夸他们是环保小卫士，他们听了心里都美滋滋的。不久，小区的人们也纷纷行动了起来，让他们的家园变得更美丽。

地球是我们共同的家园，我们应该保护它，让它变得更美丽。 环境污染的作文五

以前，奶奶家门前有一条小溪，小溪的两边像一个花园，开满了各式各样的鲜花。还有许许多多的小鱼，站在小溪里，你会觉得腿痒痒的，因为有很多小鱼在你腿边玩耍呢。

可是不久，灾难降临了。小溪的东边有一个加工厂，天天排放污水。小鱼都一只只地翻了肚皮，花儿也变得暗淡无色了，那原本像天上人间一样的小溪变成了招引无数苍蝇的臭水沟。看到这儿，我的心都碎了……但是，去年暑假我回奶奶家时，发现加工厂不见了!取而代之的却是一副全新的景象：小鱼比以前更多、更美了，是不是还跃出睡眠亲亲你的脸蛋，好调皮呀!花园又回来了，迎春花、百合花、桃花、梨花、玉兰花……小溪又这么大的变化是为什么呢?原来，政府搬迁了加工厂，找人清理了河里的杂物。附近的居民也很珍惜这失而复得的环境，只要看到脏东西和青苔都立刻打扫得干干净净。从此，奶奶家门口的小溪没有了污染，更加美丽了。

我们要保护环境，否则，我们将不再拥有这个美丽的家园——地球。 环境污染的作文六

吃过晚饭，我和妈妈出去散步。

我们行走在干净的小区道路上，两旁的树木排列整齐、交相辉映，就好像给小区披上了一件绿色的披风，显得格外美丽。我们边走边说，甭提有多高兴了。突然我们看见前面的地上乱扔了些瓜果皮，脏兮兮的，显得格外显眼。我环顾四周，心想：这么干净漂亮的小区怎么会有人乱扔垃圾呢? “扔垃圾的人真不讲文明，稍微注意一点往前走走扔到指定的地方，爱护别人也爱护自己啊!”我气愤地说。妈妈也说：“是啊，就是有个别一些人，他们只顾省事图自己方便，却一点也不爱惜公共环境。”于是我走过去，把垃圾捡起来扔到垃圾箱里去了，看着重新变得干净的小区道路，我开心地笑了，妈妈也开心地笑啦!

以后，我只要看见有乱扔的垃圾，我都会自觉地打扫干净;看见有人正准备乱扔的时候，我会及时上前阻止，告诉他们我们要爱护公共卫生。

我们只有一个地球，我们要爱护她，保护她。讲究文明、爱护公共卫生是我们每一个人应尽的义务。我们应该时刻提醒自己，从我做起，以身作则，用实际行动来美化我们的家园。

Protect our environment

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.

今年清明节时，爸爸自己动手做了清明饼，自己采的蒿青，说那才是真正的绿色食品。可谁知饼倒是做得不错，却有种怪味：汽油味。绿色食品不绿色了，反倒成了有毒食品，这是怎么回事呢？原来呀，爸爸的蒿青是在小区门口采的，那儿车辆进进出出的非常多，排出的尾气让人喘不过气儿，那小草一天24小时呆在那儿，能好吗？表面看起来绿油油的挺健康，其实早就中毒不浅了。要知道小草们的家园，我们的生活环境，早已被肮脏的恶劣的变质的空气所包围着，多么可怕呀！21世纪，大气污染，被称为社会一大公害。越是交通发达的国家，由汽车尾气排放的污染物越严重，已成为污染大气的罪魁祸首，激起了社会公愤。据各地监测分析，汽车尾气排放量已占大气污染源85％左右。目前，全世界的汽车拥有量已超过6亿辆，全世界每千人拥有汽车110辆。全世界的汽车拥有量以每年3000万辆的速度增长，预测到全球汽车数量将增到10亿辆。中国的汽车拥有量已超过1400万辆。在车辆不多的情况下，大气的自净能力尚能化解车辆排出的毒素。但眼下已车满为患，交通拥堵成为家常便饭，汽车本应具备的便捷、舒适、高效的特点却被过多的车辆逐步抵消。“汽车灾难”已经形成，汽车尾气更是害人不浅。

空气污染对人们的健康造成越来越大的威胁，而这些有毒气体70％出自汽车尾气。据医学界研究分析，汽车尾气的主要化学成分是二氧化硫、一氧化硫、氮氧化物、铅。它能引起呼吸道感染和哮喘，使肺功能下降，严重的可引起肺气肿。汽车尾气中的铅一般分布于地面上方1米左右的地带，正好是青少年的呼吸带，因而铅污染对青少年危害更重。汽车尾气中的一氧化碳与血液中的血红蛋白结合的速度比氧气快250倍。所以，即使有微量一氧化碳的吸入，也可能给人造成可怕的缺氧性伤害。轻者眩晕、头痛，重者脑细胞将受到永久性损伤；氮氧、氢氧化合物会使易感人群出现刺激反应，患上眼病、喉炎，尾气中氮氢化合物所含苯并芘是致癌物质，它是一种高散度的颗粒，可在空气中悬浮几昼夜，被人体吸入后不能排出，积累到临界浓度便激发形成恶性肿瘤。听听，多么可怕呀，可这一切又都是由人类自己造成的。人类呀，改变你们的生活方式吧！难道你们要做自己生命健康的杀手吗？

June 15th, 2006

Dear Sir or Madam,

Thank you for taking time to read this letter. As the problem of food safety has been becoming worse and worse nowadays, I am obliged to write to you.

Several days ago, one of my classmates came back from supermarket with a large bag of food. Because of having found a new style of tinned?ish in the food store, she was very glad. Several other roommates were invited to enjoy the “mouth?atering chicken”. Unfortunately, after finishing the food, all of my three friends had stomachaches and vomited, their faces having become paler and paler. Due to sensitivity to that kind of tinned food, I escaped that suffer. At that time, my mind went blank. I dialed the emergency number with my trembling hand, therefore they were quickly sent to hospital. The doctor said they were lucky to be out of danger because they did not eat too much of that rotten fish and were hospitalized on time.

This is the matter that happened around me which made me realize the seriousness of the food safety problem. I sincerely hope that the whole society could attach much importance to this issue.

Thanks!

Yours,

Julie

The protection of the border is not a new problem for us, and our government has long proposed clear targets for governance. As every ordinary person in real life, although it is impossible to work directly in environmental protection, we can start from small things and start from me. Can you raise your hand when you see the tap in the bathroom? When the battery runs out, can you classify it instead of throwing it away? How about when shopping doesnt use ultra-thin plastic bags? ...... Small things are small, but they reflect how much environmental awareness we have.

Recycling one ton of waste paper can regenerate 800 kg of paper, can save 17 tree. 20 waste recycling boxes can create a beautiful pen container. Recycling one glass bottle to save the energy, can make the bulb light for four hours. Recycling one aluminum can is to save the half oil cans. So we should place the garbage classification, reproduction by the relevant department after recycling reuse!

As long as we start from oneself, starts from the minor matter, everybody joint efforts, perseverance, we will be for the society, also a piece of clear water, blue sky for yourself, I hope everybody can voluntarily protect the environment, to make our environment more beautiful life.

境保护对我们来说并不是一个新问题，我国政府也早就提出了明确的治理目标。作为现实生活中的每一个普通人，虽然不可能都直接从事环保工作，但我们完全可以从小事做起，从我做起。当看到洗手间的水龙头在滴水时，是不是能够举手关上呢?当电池用完后能否分类收藏处理而不是随手扔掉呢?当购物时能否自觉不使用超薄塑料袋呢?……一件件小事虽然都很不起眼，但却体现我们究竟具备了多少环保意识。

回收1吨废纸可再造出800千克好纸,可以挽救17棵大树.回收20个废餐盒可以造出一个漂亮的笔筒.回收一个玻璃瓶节省的能量,可使灯泡亮4个小时.回收1个铝罐就等于节约了半个铝罐的石油.所以我们应将垃圾分类安放,由有关部门回收后再生产再利用!

只要我们从自己做起，从小事做起，大家共同努力，持之以恒，就一定能为社会、也为自己留下一片碧水蓝天，我希望人人都能自觉保护环境，让我们的生活环境更加美好。

Its our duty to protect ourenvironment. Where do we live? The earth. The earth is the only one place we live in. So you know how important the environment is.

保护环境是我们的义务。我们居住在哪里？地球。地球是我们唯一居住的地方，所以可想而知环境对于我们的重要性。

But now, some people are harming the environment, like cutting down trees, drawing pictures on public walls,litteringonto the ground. Its terrible if we still do it.

但是现在，很多人都在破坏环境，比如砍伐树木，在公共墙壁上乱涂乱画，随地扔垃圾。如果我们继续这样下去是非常可怕的。

Now, its time for all the people in the society to protect the environment. Its our duty. It needs each of us to make a contribution to improving the environment. We should make our environment more and more beautiful.

现在，是人们保护环境的时候了，这是我们的义务，我们都要为改善环境做贡献，我们应该努力让我们的环境变得更好。

星期天，妈妈带我去葡萄湖那里玩，妈妈告诉我：“葡萄湖清澈见底，非常漂亮，我听了妈妈的话，急忙让妈妈收拾东西，开车过去。”

我来到这里，立即向那里跑过去，我看着葡萄湖，惊讶极了，我问妈妈这是怎么回事，妈妈说：“原来的时候，葡萄湖清澈见底很漂亮，但是由于科技越来越发达，厂越来越多，那里面冒出的二氧化钛，让葡萄湖呼吸收了，就变成了这样。”我伤心的掉下了一颗“金豆豆”，“不哭，不哭，忘了还有一个好消息告诉你。”“那是什么?”我着急的问妈妈。“主席也考虑到了这个问题，正在想办法解决。”“耶!”我高兴的蹦了起来，妈妈也笑了。我在公园跑来跑去，直到傍晚，我累的筋疲力尽，“宝贝。我们回家吧!”我点了点头。

希望人们保护环境，不再丢垃圾。

Environmental Pollution

the problem of pollution, cause, artificial substances, release, waste products, industrial production, consumption of goods, bring it under control, agriculture, chemicalsubstancea.

Environmental Pollution

I read a piece of news recently. It says that in Japan marly businessmen ave selling fresh air to customers.and now it is becoming more and more popular. Why? --Fresh air is getting less and less in Japan, and so is it in the U. S. A.

In fact, environmental pollution is a very serious problem the whole world is facing.

it is mainly caused by the waste products released from artificial substances, industrial

production and increased consumption of goods. Bedsides, the use of chemical substances

in agriculture also causes environmental pollution.Look at the sky, you can see that dense smoke is being released from the high and big chimneys; those dirty and poisonous substances are flowing into the rivers that we use for drinking water and millions of tons of waste products are heaping around us.

How to change this condition? More and more countries are trying to work out some effective means to bring it under control, but no great success has been made.

环境污染

最近我读了一则消息说在日本，许多商人向顾客出售新鲜空气，现在这种情况越演越烈。为什么呢? 因为在日本新鲜空气越来越少，在美国也是如此。

事实上，环境污染是整个世界正在面临的一个严重问题。这主要是由于人造物质，工业生产过程中所产生的废料以及消费商品的增长造成的。另外，在农业中使用化学物品也造成了环境污染。看看天空，你可以看到浓烟从高大的烟囱中释放出来，这些脏而有毒的物质流入我们赖以饮水的河流，数百万吨废物正堆积在我们周围。 中国大学排名

怎样改变这种状况呢？越来越多的国家正在试图拟定出一些有效措施控制环境污染，但至今成效不大。

After entering college, we found, to our surprise, that differences between high school life and college life are great. In high school, we always depended on our parents and teachers to solve all kinds of difficult problems. At college, however, we have to rely exclusively on ourselves. Whats more, we have to learn how to get along with our classmates and roommates.

Four years at college is an important yet very short period of time in our life. So it is always expected that we adapt to this life as quickly as possible. But it is a pity that not everyone can do so immediately. Here are some suggestions.

First, get familiar with the main buildings on the campus. Spend one or two hours by yourself or with your classmates to go around the campus so that you can know the location of such important places as the library, the dining room, the post office, the clinic and classrooms. Next, try to be independent. Learn to do such things as making sound decisions on how to spend your time, how to spend your money etc, and washing clothes on your own. Furthermore, form good study habits. Talk with your classmates and learn from their good habits. Finally, try to take part in all kinds of activities to get out of your solitude and get on well with your classmates.

每当我看见垃圾都忍不住要去清理，一点也不留，保持城市环境清洁，全靠你我他，我们怎么能让绿色的城市污染斑斑呢？

有一天，我在小区墙上看见很多小广告，就拿回家清理小广告，准备刮了小广告。我先拿来刮棒，使劲的刮，可是，我怎么也没有想到，广告刮也刮不下来。我想：难道是贴小广告的人用了什么材料，贴上去吧？我想着想着挑来一桶水，往上一泼，真的有一些掉下来了，接着，我使劲的刮，这次终于刮下来了，但是我发现地上有一些白色的小东西，回家查了下，原来这种东西会让人得牛皮癣，于是，我拿扫把把这些白色的小东西给清理了，感觉轻松了很多，旁边的老奶奶夸我是个好孩子。

经过这件事之后，我明白，如果人们都举手之劳的小事做好，世界将会更加美好。

World Cup (soccer), two international soccer tournaments, one for men and one for women, each held every four years. Both tournaments are the pinnacle of international competition in the sport.

The mens World Cup is considered the most popular sporting event in the world and is followed with passionate interest around the globe—the final game of the 1998 tournament was played to a television audience of more than 1 billion viewers. Founded in 1930 with just 13 teams, the tournament now attracts entries from more than 140 countries. The teams must participate in elimination games within their own continents before qualifying to become one of the 32 nations participating in the final tournament. The womens World Cup was first played in 1991 and has gained popularity steadily since then. More than 90,000 fans attended the finals of the 1999 tournament—one of the largest crowds ever to witness a womens sporting event. Nearly 75 nations attempted to qualify for the 1999 event, which was a 16-team elimination tournament.The FIFA World Cup (often called Football World Cup, The World Cup, or simply World Cup) is the most important competition in international football (soccer), and the worlds most repreteam sport event.

Organised by Federation Internationale de Football Association (FIFA), the sports governing body, the World Cup is contested by mens national football teams which are FIFA members.

The World Cup is held every four years, but the qualifying rounds of the competition take place over a three-year period, using regional qualifying tournaments. 197 national teams entered the qualification tournaments for the 2006 World Cup. The final tournament phase involves 32 national teams competing over a four-week period in a previously nominated host nation.

The World Cup final competition (often called the "Finals""), which has

been held every four years since 1930, except in 1942 and 1946 when it was cancelled due to World War II, is the most widely-viewed and followed sporting event in the world. It has a global audience of more than 3 billion people (half the worlds population) exceeding even the Olympic Games.

世界杯(足球)，两个国际足球锦标赛，一个男人和一个女人，每四年举行一次。这两项赛事都是体育界国际竞争的顶峰。

男子世界杯被认为是世界上最受欢迎的体育赛事，紧随其后的是全世界的热情，1998场比赛的最后一场比赛是由超过10亿名观众观看的。成立于1930，只有13支球队，现在的比赛吸引了来自超过140个国家的参赛作品。参赛队伍必须在自己的大洲参加淘汰赛，才能成为参加决赛的32个国家之一。女足世界杯于1991首次出现，此后一直稳步普及。超过90000球迷参加了决赛的1999场比赛的最大的人群之一，见证了女子体育赛事。近75个国家参加了1999事件，这是一个16队的淘汰赛。国际足联(常称为世界杯足球世界杯，世界杯，或只是世界杯)是国际足球最重要的比赛(足球)，和世界上最repreteam体育赛事。

由国际足球联盟组织(国际足联)，这项运动的管理机构，世界杯是有争议的，是国际足联的成员国家男子足球队。

More and more people have become aware of the significance of work efficiency. What does workefficiency mean?First of ali, it means working without any waste of time. A person with efficiency can produce more things in less time. In addition, work efficiency is closely linked with better quality of work results.

Many people are interested in improving their work efficiency because it can bring a lot of benefits both to an individual and to the society.The most obvious benefit of work efficiency is that a person can use the time saved to do a lot of other valuable things.For example, a student who studies with high efficiency can win time to read more books, and to be engaged in more activities. Another benefit is that a person who works efficiently can have more leisure time to enjoy life. He can do whatever he likes to do in his leisure time, such as listening to music,going to movies, shopping, and touring.

High efficiency in work will undoubtedly lead to the great increase of output and the improvement of the quality of products, which will, in turn, contribute to the development and the prosperity of the society.

星期天，我去姥姥的老家玩。走在路上，一望无边的田里，农民正忙碌着收割庄稼。突然，一阵阵黑烟飘来，呛的我直咳嗽。我一边跑一边问：“这是哪儿来的烟？呛的我快受不了啦！”旁边的人也直抱怨：“是呀，这几天焚烧麦杆，我们坐在附近的也倒霉了！”另外一个人也连忙接话：“是呀，这样下去世界会变成啥样子呀！”看着滚滚浓烟，我仿佛看到了许多年以后的情景：

早晨刚开门，一阵黑烟直扑进来，人们不得不戴上厚厚的口罩。回家一进门就要赶紧把门窗关紧，否则全家人就得不停在咳嗽。尽管室内空气混沌，人们却不能打开窗户透透气，也不敢出门游玩。从窗户望出去，浓烟滚滚，空气再也不清新了。花草树木有的熏死了，活着的也一个个耷拉着脑袋。公园里最漂亮的景点也折腾的不成样子了，儿童乐园、麦香村等商店有时一个人也没来，最后只好倒闭。人们在家里没事做，快闷死了，小孩更是哭着闹着，大人也无可奈何地唉声叹气。

我想着想着，不禁大叫：“人们，不要再污染环境了，这样下去我们怎么受得了啊！”一旁的农民说：“你说的倒好，草杆不焚烧怎么行？”我愤愤不平道：“谁能发明一个自动焚烧器多好呀，焚烧的又好又不污染环境，照这样下去，世界真变得不知成啥样子了！”农民嘲讽道：“你来发明呀，你发明出来，我把全部家当送给你！”“我一定能发明的出来！”“你试试呀！”我大声叫道：“我长大了一定要发明一个！”

说完，我转身和家人一起上了长途汽车，车开远了，农民们还在后面嘲笑：“输了吧……”

空气中有人类赖以生存的氧气，没有氧气人类就不能生存!然而，人们却在生活中不断地污染空气。

星期六早上，我和爸爸在散步。路上，我看见一家工厂的烟囱上面在冒烟，附近一片天空都变黑了，平日在天空翱翔的小鸟也不见了。路上驶过一辆辆汽车，车尾的尾气和烟囱排出的废气一样，乌黑一团，并伴有难闻的气味。我顿时意识到，这乌黑的一团烟是杀手，是危害我们健康的杀手。

为了保护环境、净化空气，我觉得我们应该多种植物。另一方面，科技越来越发达，我们应该让进步的科技帮助工厂少排废气，甚至不排废气。同时，我们也要在尽量不污染空气的前提下让科技进步。总而言之，没有了清新甜润的空气，就不会有人类美好的生活!

环境的污染和破坏，对人们的身体健康影响很大。儿童时期是人一生中生长发育的初始阶段，身体各部分器官还未成熟，环境污染对孩子们健康肌体的损害就更加严重。空气污染主要来自燃料的燃烧、工业生产过程和汽车废气。科学家们测算，烧1吨煤要排放20-80公斤烟尘，炼1吨钢要产生60立方米烟尘，汽车跑1小时要排出40-100立方米废气，它们都严重地污染了空气。

污染了的空气中含有灰尘、一氧化碳、二氧化硫及各种有毒有害物质，侵入孩子的呼吸；系统可引起感冒、鼻炎、哮喘等疾病，而且，还会影响嗅觉和呼吸功能。据沈阳市有关部门测定，生活在重污染区的孩子有20%嗅觉迟钝〈在清洁区只占5%〉；有45．1%的孩子鼻粘膜充血，并经常有鼻涕流出；有9．8%的孩子眼晴长期红肿，经常流眼泪（在轻污染区只有16%的孩子鼻粘膜充血和1%的孩子眼睛发炎）。

汽车废气中含有铅物质。据统计，全世界现在每年从汽车排出的废气中所含的铅达40多万吨，这些含铅的废气（烧基铅）也威胁着少年儿童的健康。烧基铅最容易随空气进入孩子们的呼吸道，虽然每次吸入的含铅废气是微量的，但由于它们是蓄积性毒物，毒性较大，故对儿童危害较大。经科学研究表明，微量的铅污染，就足以使孩子们的身体和智力受到损害，推迟大脑发育或诱发急性脑症。恶臭污染也严重地危害着孩子们的健康。恶臭主要来自化工肥料、造纸、制革等工厂在生产过程中排放的废气。另外，由于一些人的社会公德和环境意识差，不讲究卫生，随地大小便，以及乱丢的果皮和乱倒的垃圾，都会产生恶臭气体。人们生活在恶臭的环境中，会出现恶心、头痛、疲劳等症状。水是人类生命的源泉，水的污染对儿童身体健康危害极大。随着现代工jk的发展和人口的不断增长，水的污染日趋严重。工业污水和生活污水中的有毒有害物质，经过多种途径污染着地面水和地下水，而农药和工业废气、废渣中的有害物质，经雨水的冲刷溶解，也污染了水源。少年儿童饮用了污水后，会引起急性或慢性中毒，以致影响身体发育。饮水中氟含量大时，会得氟骨症、牙齿松脱症。电镀废水中含有很多有毒物质，如未经处理就排入水中，它的危害性极大。饮用水被肠道致病菌污染后，会引起霍乱、伤寒、肝炎等疾病的流行。

噪声对少年儿童的健康危害极大。生活在城市里，喇叭声、撞击声、轰鸣声、爆裂声、吵闹声以及电视机、收录机等家用电器发出的噪音都会影响孩子们的身体健康。噪音在当今世界上的很多国家，都已成为公害之首。噪音可以使人头痛、昏晕、智力衰退。受噪音影响的时间长了，还可能引起心血管系统的疾病，有时会使血压升高，甚至使人发疯。

据调查，在美国洛杉矶国际机场附近上小学的儿童，每天都听到喷气式飞机起飞和降落的噪音，因而普遍患有持续的高血压症。

我国的环境专家曾对居住在某铁路边的青少年进行过心脏和脑神经健康状况的检查，然后通过电子计算机进行分析，证明噪音会损伤心脏，噪音也会影响儿童的智力发育，吵闹区的儿童智力比安静区低20%，长期生活在铁路旁受噪音影响的青少年儿童健康的危害已经引起全社会的关注。

As soon as I was enrolled in college I reit a big burden off my mind. So did my classmates. We just wanted to relax. But at our first English Lesson on how to improve our study the teacher told us," There is no end to learning. You can only become a top student with additional work." And she says hard work is rewarding.

The teachers words awakened me. In fact everyone in the world is always learning. Mans talents are like wild plants. They need cutting and pruning with the tool of learning, We lears not only inside the classroom but also outside the classroom. Learning is a process in which man adapts to his surroundings. It is driven by mans desire to win respect and to contribute to society. It is the curiosity for knowledge stimulated by knowledge itself." To learn is to be young. Not to learn is to die." This saying applies to every society and to all ages.

Indeed, everyone living on earth is learning all the time. Man learns not only from books but also from his own experience We can not hope that as long as we learn we will gain benlfits. Efficient study is inseparable from good methods and motivation, A man of a strong sense of responsibility and full of ambition is insatiable in learning.

I entered the university after much efforts. I know it is only the first step on the road leading to the sea of knowledge. It is but the first page in the book of science. The further away ! am off shore, the more far-sighted! will be. The more you learn. the more you feel the need to learn. Art is long, life is short.

一进大学，我感到思想上卸了一个包袱，就像我们的同班同学一样，大家都想放松一下。可在如何提高学习水平的笫1堂英语课上，老师就对我们说：“学无止境。只有通过努力才能成为优等生。”同时还说努力学习是会有报偿的。

老师的话唤醒了我。事实上，世上每一个人都在学习。人的才能如野生植物，需要用学习这把工具予以修剪。我们不仅在课堂上学，而且还要在课外学。学习就是不断适应环境的过程。学习受“人要赢得尊重，就得对社会做贡献”的欲望所驱使。学习就是知识本身所引起的对知识的好奇。“学习使人年轻，不学习等于死亡。”这句话造用于任何社会、任何时代。

确实，世人无时不在学习。人不仅从书本上学，而且在经验中学。我们不能指望只要学习就必有所获。有效的学习是与好的方法与动机分不开的。责任心强且有抱负的人会学而不厌。

经过努力，我进了大学，但我知道，这只是通往知识海洋上的第一步，只是科学这本书中的第1页。离岸越远，视野越宽。越学越想学。生命短暂，艺术无涯。
