學(xué)農(nóng)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.
“空氣”英語(yǔ)作文譯文：
我們周?chē)目諝鈱?duì)大家都很重要。沒(méi)有空氣，我們就無(wú)法生存。每個(gè)人都明白這一點(diǎn)。但是在很多其他方面――那些不大明顯或不大為人所知的方面，空氣也是必不可少的。
比如，沒(méi)有空氣就沒(méi)有聲音，因?yàn)槁曇羰峭ㄟ^(guò)空氣傳送的。沒(méi)有空氣也就沒(méi)有火，也就沒(méi)有汽車(chē)，因?yàn)槠?chē)發(fā)動(dòng)機(jī)需要空氣來(lái)運(yùn)轉(zhuǎn)。
沒(méi)有空氣就沒(méi)有風(fēng)，沒(méi)有云，沒(méi)有天氣。夜晚會(huì)非常冷，白晝會(huì)非常熱。我們會(huì)被迫對(duì)找地方躲避陽(yáng)光，因?yàn)闆](méi)有大氣層保護(hù)我們不受致命光束的侵害。
大氣就是環(huán)繞地球的空氣。大氣壓則是所有空氣對(duì)地球表面形成的'重量。正如大家所知道的，地球上許多事情離開(kāi)氣壓就無(wú)法實(shí)現(xiàn)。在此不再枚舉 。
一句話，離開(kāi)空氣，我們就無(wú)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.

Poeple in villages are healthier than people in towns. That is because the air in villages is very fresh. Farmers are working all day in the fields, breathing fresh clean air. But there are too many factories in cities.
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!

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.
