health, surrounded by, smog, anything but, gases, impurities, absorb, poisonous, try hard, blacked out

　　We all know that clean air is important to good health. Wherever you go and whatever you do, you are always surrounded by a sea of gases that we call air. If there are impurities in the air, they may be absorbed by our bodies and make us ill. We need clean air, but unfortunately, air pollution is globally present, especially in cities.

　　Many large cities are anything but pollution-free. Our cities have many factories, which we need to make food, clothing and other things. Every year these factories pour millions upon millions of tons of smog into air. Power plants and houses that burn coal add greatly to air pollution. Besides, there are more cars in cities now. Once out on the streets, they will take in fresh air and replace it with poisonous gases.

　　Our country is trying hard to prevent and control air pollution. As long as every citizen also realizes its importance and makes join efforts, the day will come soon when people will take in only clean air. Then, the sunlight will no longer be blackened out by smoke and soot.

　　健康,包圍,煙霧,除了氣體、雜質(zhì),吸收,有毒的,努力,昏了過去

　　我們都知道清潔空氣對于健康是很重要的。無論你去哪里,無論你做什么,你總是被海洋包圍的氣體,我們稱之為空氣。如果空氣中有雜質(zhì),它們可能會被我們的身體吸收,使人生病。我們需要清潔的空氣,但不幸的是,空氣污染是目前全球,尤其是在城市。

　　許多大城市都無污染。我們的城市有很多工廠,我們需要食物,衣服和其他東西。每年這些工廠倒成百上千萬噸的煙霧進入空氣。燃燒煤炭的發(fā)電廠和房屋也大大加重空氣污染。除此之外,在城市有更多的汽車。一旦在街上,他們將在新鮮空氣和有毒氣體取代它。

　　我們的國家正努力預防和控制空氣污染。只要每個公民也意識到它的重要性,使加入的努力,這一天很快就會到來,當人們將只在清潔空氣。然后,陽光將不再是黑煙,煙灰。
