Clean air is made up of only nitrogen, oxygen, and water. As we have industrialized, our cities have grown and traffic has increased. With these development there has come an increase in the number of by-products released into the air, such as particles（细粒）from burning fuels and poisonous gases from chemical reactions. These gases become pollutants.
Air pollution has a bad effect on the earth and our environment. Air pollution can result in acid rain, and it can also lead to the Greenhouse Effect—a condition in which pollution stops radiation from traveling out of the Earth’s atmosphere. This upset to the natural process means that temperatures on Earth may not be maintained within natural ranges. Due to the Greenhouse Effect, temperatures on Earth become warmer, which is known as global warming. What’s worse, air pollution may produce holes in the ozone layer（臭氧层）— this layer of ozone naturally prevents ultra-violet rays （紫外线） from the sun reaching Earth. Holes make it possible for the rays to reach us.
Don’t let all the bad news about air pollution get you down because there are many ways to help fight the air pollution. Every one of us can employ a variety of air pollution solutions. A smoker can give up smoking. While shopping, you can choose organic and natural cleaning products. Driving less and carpool more can also contribute to less pollution. Next time, keep your air-conditioning low. Of course you can plant more trees.
Air pollution is a major problem for our planet. However, as long as we realize how serious the air pollution is and take actions now, everyone can make a difference!

In the year 1986 there was a terrible explosion(爆炸). The explosion was at a nuclear power plant(核电站) in Ukraine. The radiation(辐射) caused a lot of damage. It polluted the soil and other things. People were living in the area when the explosion happened. More than twenty years later those people are still suffering. The influence of the explosion will go on for a long time.
Over two million people still live in that area. Only 56 people died from the explosion but many other problems have been caused because of it. Some types of cancer are more than 200 times above the world average(平均水平). Many children have cancer now and children born with problems have doubled since the accident.
Some people in the United States are worried about the children living in the explosion area. One group has been trying to raise money. They are called the Chenobyl Children’s Project. They want to bring children from Ukraine to the U.S. each summer.
A spokesperson for the group says that radiation is the highest in the summertime so it is a good time to get the children out of the country. They want to help the children get away for a little while. The Project wants them to be safe from radiation.
It costs $1,500 to bring each child to the United States for six weeks. The group raised enough money to bring 28 children to the United States last year. The children were able to do lots of fun things. They enjoyed clean air, healthy food, and plenty of outdoor fun. One little nine-year-old girl who got to come to the United States said that she likes America.
The spokesperson says that the children that come to America during the summer miss less school when they return home because they have a long summer vacation.

【小题1】Where did this most popular day for couples come from? And how does it come into beings, year after year?

【小题2】The first Earth Day in 1970 was a raucous, radical teach-in that helped spur clean-air, clean-water, and endangered species legislation in the United States.
