[EX Q]: Article: In the summer of 1885, nine-year-old Joseph Meister was very ill. He had been wounded by a sick dog that had rabies , a very dangerous disease. His parents were told that there was probably only one man who could save Joseph's life----Louis Pasteur. When Pasteur was a young boy in France, he spent many hours every day with the chemist who lived in his small town. At that time, the chemist had to make all the medicines himself. Young Louis enjoyed watching the chemist as he worked and helped those people who came to him each day. As a school boy, Pasteur worked slowly and carefully. At first, his teachers thought that young Louis might be a slow learner. Through elementary school, high school, and college, Pasteur worked in the same thoughtful way. Then he became a college professor and a scientist , and he continued to work very carefully. Pasteur was studying about the germs that cause rabies when Joseph Meister became ill.In fact, Pasteur believed he had a medical treatment for rabies, but he had never given it to a person before. At first, Pasteur was afraid to treat Joseph, but the poor child was dying. Pasteur gave Joseph an inoculation every day for ten days. Slowly, the child became better. During his lifetime, Pasteur studied germs and learned how they cause diseases in animals and people. He developed vaccinations that prevent many of these diseases. On September 28,1895, Louis Pasteur passed away, at the age of 72. The work of this great man has been of great help to modern medicine.

[EX Q]: Article: A green house is a building made of glass which is used for keeping warm when the outside temperature is low. In a similar way there are several gases in the atmosphere (mixture of gases that surround the earth) which trap the heat produced by the sun and prevent it from escaping. These gases are known as "greenhouse gases". 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 gases exist naturally in small amounts in our atmosphere, and without them the 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 many of these gases into the earth's atmosphere by burning large quantities of coal and oil and by cutting down forest. The rapid increase in greenhouse gases 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 of between I and 4degC;. 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 gases put into the atmosphere before the 1960s. Since then, our use of these gases has greatly increased.
Answer: a natural course that is to a certain degree useful to us
[EX A]: According to the passage, we can know "greenhouse effect" means _ .

[EX Q]: Article: My sister Grace Halloran spent most of her teen years in and out of the juvenile institutions for minor offenses but, at 18 she was sent to prison for stealing a car.

She swore to find something, anything, to prevent him from facing her fate. When conventional medicine offered no hope, Grace began a personal _ . She entered a local college. The office for disabled students had her reading assignments put on cassette tapes so that she could listen and learn. She began studying anatomy, physiology and other health sciences. Everyone knowing her was astonished at her persistence to educate herself, restore her vision and keep focused on raising a son who would have perfect eyesight. Eventually Grace's own way worked and she earned the PhD. in Holistic Health for her successful work in improving serious eye disorder. Her eyesight slowly improved so much that she was able to qualify for a driving license. Even better, her son had perfect vision and was accepted into the Air Force.
