学农作文600字1

　　the air surrounding us is important to everyone. without air, we could not exist. everyone understands that. but air is necessary in many other ways――ways that are not always so obvious or widely known.

　　for example, if we did not have air, there would be no sound, because sound travels through air. without air there would be no fire. there would be no automobiles, since motors need air in order to operate.

　　without air, there would be no wind or clouds. there will be no weather. the night time would be very cold and the day time very hot. we woud be forced to seek shelter from the sun, as there would be no atmosphere to protect us from the sun's deadly rays.

　　the atmosphere is all the air surrounding the earth. atmospheric pressure is the weight of ail the air against the surface of the earth. many things on earth can not do without atmospheric pressure, as everyone knows. i won't give further examples.

　　in one word, we can not live without air.

　　“空气”英语作文译文：

　　我们周围的空气对大家都很重要。没有空气，我们就无法生存。每个人都明白这一点。但是在很多其他方面――那些不大明显或不大为人所知的方面，空气也是必不可少的。

　　比如，没有空气就没有声音，因为声音是通过空气传送的。没有空气也就没有火，也就没有汽车，因为汽车发动机需要空气来运转。

　　没有空气就没有风，没有云，没有天气。夜晚会非常冷，白昼会非常热。我们会被迫对找地方躲避阳光，因为没有大气层保护我们不受致命光束的侵害。

　　大气就是环绕地球的空气。大气压则是所有空气对地球表面形成的'重量。正如大家所知道的，地球上许多事情离开气压就无法实现。在此不再枚举 。

　　一句话，离开空气，我们就无法生活。

　　Air is all around us. It is around us as we walk and play. From the time we were born air is around us on every side. When we sit down, it is around us. When we go to bed, air is also around us. We live in air. We can live without food or water for a few days, but we cannot live for more than a few minutes without air. We take in air. When we are working or running we need more air. When we are asleep, we need less air. We live in air, but we cannot see it. We can only feel it when it is moving. Moving air is called wind. How can we make air move? Here is one way. Hold an open book in front of your face, close it quickly. What can you feel? What you feel is air.

　　空气

　　我们周围到处都是空气。当我们走路和玩耍时，它就在我们身边。从我们出生的那一刻起，空气就在我们身边。当我们坐下时，它就在我们身边。当我们上床睡觉时，空气也在我们周围。我们生活在空气中。没有食物和水我们可以活几天，但是没有空气我们不能活上几分钟。我们接受空气。当我们工作或跑步时，我们需要更多的空气。当我们睡着的时候，我们需要更少的空气。我们生活在空气中，但我们看不见它。只有在移动时我们才能感受到它。移动的.空气叫风。我们怎样使空气运动?这里有一条路。把一本打开的书放在你面前，快把它合上。你能感觉到什么?你所感受到的是空气。

　　They produce more and more harmful gases. At last, cities are full of smoke. And there's many dust in cities,too. It may cause a disease.

　　So fresh air is very important to the people in cities. We need fresh air. So please don't pollute the air!

学农作文600字5

　　air pollution is one of the major problems of the modern world. a great deal of energy is needed to run the factories of modern industrial nations. automobile, trains, planes and busses need energy, too.

　　nearly all of this energy is produced by burning fuels. the burning produces wastes, some of which remain in the air, causing air pollution.

　　scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities. they are studying new ways of generating electricity that may be less damaging to the environment. in the meantime, many power plants are being modernized to give off less polluted material. also, engineers try to design and locate new power plants to do minimum damage to the environment.

　　however, it may be that we still have a long way to go before we have a "clean" world. nearly all of the countries are trying hard to prevent and control air pollution.

　　there indeed seems to be no end to tasks that environmentalists will be required to do. people will continually find new ways to control pollution.
