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（細(xì)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（臭氧層）— this layer of ozone naturally prevents ultra-violet rays （紫外線） 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(核電站) in Ukraine. The radiation(輻射) 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.

C．The influence of the explosion will last for more than 20 years.
D．Millions of people still live in the area where the explosion happened.
【小題2】Why does the group bring children to the U.S. in summer?
A．Because the radiation is the highest in summer.
B．Because children have a long summer vacation.
C．Because the U.S. is the most beautiful in summer.
D．Because traveling in the U.S. in summer costs the least.
【小題3】Which of the following is TRUE about the Project?

以下是這些報(bào)道的簡(jiǎn)要內(nèi)容介紹，請(qǐng)配對(duì)它們的標(biāo)題。
【小題1】Where did this most popular day for couples come from? And how does it come into beings, year after year? Noel Lenski, professor of the University of Colorado, said the lovers’ holiday traces its roots to raucous annual Roman festivals held every year on February 15 and remained wildly popular well into the fifth century A.D.
【小題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. Now, 40 years later, Earth Day is every day, as the saying goes. The thing is, it’s also everyday- environmentalism that has become a routine with greenness as much a marketing tactic as a moral pursuit.
【小題3】Some 242 million turkeys were raised in the U.S. in 2010 for slaughter, according to the U.S. Department of Agriculture’s National Agricultural Statistics Service. Last year’s birds were worth about U.S. $3.6 billion. Before the big dinner, debunk the myths, we need to know that the first “real” U.S. Thanksgiving wasn’t until the 1800s and get to the roots of Thanksgiving 2010.
【小題4】Father’s Day traditionally takes a backseat to Mother’s Day, and, for the most part, dads are cool with that, experts say. Nevertheless, as traditional roles around the house gradually change, fathers are gaining more attention on their special day, at least as measured in the monetary value of gifts estimated to be given on June 19, 2011, when the holiday will be celebrated in dozens of countries.
【小題5】Cookouts, fireworks, and, of course, a chance to wish Uncle Sam a big “happy birthday” —the day means summer in full swing across the United States and beyond. Besides the founders of the US, Fireworks, first authorized by Congress in 1777, are another legacy. More than 14,000 fireworks displays light up U.S. skies each year.

Many people who work in London prefer to live outside it, and to go in to their offices or schools every day by train, car or bus, even though this means they have to get up early in the morning and reach home late in the evening. 

One advantage of living outside London is that houses are cheaper. Even a small flat in London without a garden costs quite a lot to rent. With the same money, one can get a little house in the country with a garden of one’s own. 

Then, in the country one can rest from the noise and hurry of the town. Even though one has to get up earlier and spend more time in trains or buses, one can sleep better at night and during weekends and on summer evenings, one can enjoy the fresh, clean air of the country. If one likes gardens, one can spend one’s free time digging, planting, watering and doing the hundred and one other jobs which are needed in a garden. Then, when the flowers and vegetables come up, one has the reward of one who has shared the secret of Nature. 

Some people, however, take no interest in country things: for them, happiness lies in the town, with its cinemas and theatres, beautiful shops and busy streets, dance-halls and restaurants. Such people would feel that their life was not worth living if they had to live it outside London. An occasional walk in one of the parks and a fortnight’s (two weeks) visit to the sea every summer is all the country they want: the rest they are quite prepared to leave to those who are glad to get away from London every night. 

 

1. Which of the following statements is NOT true? 

A. People who like country things prefer to live outside the city. 

B. People who work in London prefer to live in the country. 

C. Because of certain disadvantages of living outside London, some people who work in London prefer to live inside London. 

D. Because of certain advantages of living outside London, many people who work in London prefer to live outside London. 

2.One can use the same money for ________ to buy a little house with a garden in the country.

A. getting a small flat with a garden            B. having a small flat with a garden

C. renting a small flat without a garden        D. buying a small flat without a garden

3.When the flowers and vegetables in the garden come up, those _______ have the reward of one who has shared the secret of Nature. 

A. who live in the country                        

B. who have spent time working in the garden

C. who have a garden of their own                    

D. who have been digging, planting and watering

4. People who think happiness lies in the town would feel that _______ if they had to live it outside London. 

A. their life was meaningless              B. their life was invaluable

C. they didn’t deserve a happy life      D. they were not worthy of their happy life

5.The underlined word “rest” in the last paragraph refers to ________.

A. the rest time                                         B. the rest people

C. the rest of the country                                D. the rest of the parks and of the sea
