A greenhouse is a building made of glass which is used for keeping plants warm when the outside temperature is low. In a similar way there are several gasses in the atmosphere which trap(捕捉) the heat produced by the sun and prevent it from escaping. These gasses are known as “greenhouse gasses”, and the way in which they trap heat in the atmosphere is called the “greenhouse effect”. This is not simply air pollution. Most of the main greenhouse gasses exist naturally in small amounts in our atmosphere, and without them earth would be 30 degrees colder and human life would not exist. In other words, the greenhouse effect is a natural course which is to some degree helpful to us.
The problem is that in the last century and a half, we have been putting too much of these gasses into the earth's atmosphere by burning large quantities of coal and oil and by cutting down forests. The rapid increase in greenhouse gasses is making the world warmer. The world's temperature has already gone up by half a degree this century, and the sea level has risen by 10 centimetres. If the amount of carbon dioxide in the atmosphere doubles, there will probably be a rise in the earth's temperature between 1 and 4. This may seem a small increase, but it would be enough to cause major changes in geography and agriculture. Large areas of the world would be flooded, and some areas would become dry and unable to produce crops:It is important, too, to consider that there may be a delay of about 30 years in the greenhouse effect. This means that we are probably experiencing only now the effect of the gasses put into the atmosphere before 1960s. Since then, our use of these gasses has greatly increased.

阅读下列短文,掌握其大意,然后从每题所给的四个选项(A、B、C、D)中选出最佳选项。
Lisa is ten years old. She is handicapped(残疾) because she has brain damage. She could not do even the most simple thing until a year ago. She could not comb her hair or feed herself. Her parents loved her. But they treated her like baby.
Mr Ching has a daughter and a son. They are both grown. They live far from their father. Mr Ching felt lonely. He decided to do something about it. He decided to become a foster grandfather to a handicapped child. And that was how he met Lisa.
Foster grandparents are grandparents who are not related by birth. But foster grandparents love the children they care for. They love them just as natural grandparents love their grandchildren.
The foster grandparents also help the handicapped children in special ways. They help to dress and feed the children. They read to them and tell them stories. They also help with the handicapped children's therapy. Therapy is the treatment of a disease or disorder. It helps the children overcome their handicaps.
Mr Ching became a foster grandparent to Lisa when she was nine years old. At first, Lisa was shy. She was afraid because Mr Ching was a stranger. But he came to see her every day. Gradually, she began to trust him.
At last Lisa let Mr Ching do things for her. He came at lunch time and fed her. One day he handed her the spoon and guided it to her mouth. He told her she must learn to feed herself.
“Most of that lunch ended up on us instead of in Lisa's mouth,”Mr Ching remembers.“But it was a start for Lisa. She learned to feed herself in a few months.”
Then Lisa was ready for more therapy, thank to Mr Ching. She had learned to do one simple thing. She could learn to do other simple things. Mr Ching was trained to help with Lisa's therapy.
To become foster grandparents, people must be at least sixty years old and in good health. They must be willing to give their time to handicapped children. They are volunteers, so they are not paid. They are given money for expenses, such as transportation.
Mr Ching speaks for most foster grandparents when he says,“We all benefit. The handicapped children benefit because we help them live more useful lives. And we benefit because we know the children need us and love us. For any person, there's no greater happiness than that!”
