For years scientists have been worried about the effects of air pollution on the earth’s natural conditions. Some believe the air inside many houses may be more dangerous than the air outside. It may be one hundred times worse.
Indoor air pollution can cause a person to feel tired, to suffer eye pain, headache and other problems. Some pollutants(污染物)can cause breathing disorders, diseases of blood and even cancer. Most scientists agree that every modern house has some kind of indoor pollution.
People have paid more attention to the problem now. It is true that when builders began making houses and offices they did not waste energy. To do this they build buildings that limited the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to let out harmful gases.
As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control system for building—green plants. Scientists do not really know how plants control air pollution. They believe that a plant’s leaves absorb(吸收)or take in the pollutants. In exchange the plant lets out oxygen through its leaves and tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each absorbs different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and healthier place.

When I was 12 years old, I was at a very hard stage in life. I was short and fat, which was bad for a girl, so coordination(协调)was not one of my strongest features. On the other hand, my mother was a very talented
softball player who even acted as my coach. Night after night, I would try my best to impress “my coach”.Unfortunately, I just felt like a terrible disappointment to my mother.
One summer afternoon, my mother told us we were going to visit Uncle David. Since we lived in an apartment, going to the country was quite a treat. My uncle David always had a way of making me feel special.
When we arrived, my uncle and cousin Jeff were throwing metal rings at two holes in the ground. I was curious about what they were doing so I went over to watch. Noticing that I was standing there, my uncle asked if I had ever played washers.
Being a “city girl”, my reply was that the only “washers” I knew were the ones that cleaned clothes. To my embarrassment, Uncle David, chuckling(咯咯笑),explained that the metal rings were called washers. I was shocked to hear my uncle saying he wanted me to take his place. He then gave me the washers and gave tips on how to throw better.
Unwillingly, I joined Jeff. Gradually, I found myself not only enjoying but also wanting to win this game. The washer went into the air and began to fall. Then a cloud of dust appeared as the washer sank into the hole. My first try! I had actually thrown the washer into the hole!
Although 23 summers have gone by since that day, this small success in washer playing helped me get back self confidence lost when I struggled with the game of softball.
1.Why did the author live a hard life at the age of twelve?
A. Because her body has many health problems.

B. the author’s mother was good at softball
C. the author had never met Uncle David before the visit

4.Which is the RIGHT time order of the changes in the author’s feelings when she was at her uncle’s?

What is your favourite colour? Do you like yellow, orange, red? 1. Do you prefer greys and blues? Then you are probably quiet, shy, and you would rather follow than lead. You tend to be pessimist. At least, this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of colour preference, as well as the effect that colours have on human beings. 2. If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.
3. A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. 4. A black bridge over the Thames River, near London, used to be the scene of more suicides than any other bridge in the area ------ until it was repainted green. The number of suicide attempts immediately fell sharply. Perhaps it would have fallen even more if the bridge had been done in pink or baby blue.
5. It is an established fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or grey.
A. They tell us, among other facts, that we do not choose our favourite colour as we grow up ----- we are born with our preference.
B. On the other hand, black is depressing.

A famous doctor once received a little child who was badly ill. Thanks to his skill and care, his young patient got well and was soon able to get up and run about again.
The child’s mother was very much obliged to the doctor, and she called on him to thank him for what he had done for her child. “Doctor,” she said, “you have saved my little son. I don’t know how to thank you enough. I feel that money alone cannot repay you, so I have made this little purse with my own hands, as a sign of my gratitude. I hope you will accept it.” The doctor stood up and said coldly, “Madam, a little present like that is very nice between friends, but a doctor needs to be paid properly for what he has done.” The lady was so surprised and hurt so much that she could not reply for a moment. Then she said quietly, “Perhaps you will tell me how much your fee is?”
“Fifty pounds”, he answered.
