　 　 Industrial pollution is not only a problem for the countries of Europe and North America but also an extremely serious problem in some developing countries.１ They want to introduce industries, and so they put few controls on the industries which cause pollution.

　 　 Cubatao, an industrial town of 85 000 people in Brazil, is an example of the connection between industrial development and pollution. In 1954, Cubatao had no industry.２　The people of the town are suffering from the poisonous matter in their environment．３ Birth shortcomings are extremely common. Among children and adults, lung problems are sometimes twelve times more common in Cubatao than in other places.

　　　４ However,  these laws are not strict enough. It is cheaper for companies to take no notice of the laws and pay the fines(罚款) than to buy the expensive equipment that will reduce the pollution. It is clear, therefore, that economic growth is more important to the government than to the health of the workers.

　　　However, the responsibility does not completely lie with the Brazilian government. ５A number of the factories in the town are owned by large companies from France, Italy, and the U. S. They are doing things in Brazil that they would not be able to do at home. If they caused the same amount of pollution at home, they would be severely punished or even put out of business.

A．So the bad effects can be clearly seen.

B．It is true that Brazil has laws against pollution,

C．For these countries, economic growth is a very important aim.

D．The pollution in Cubatao is caused by the changes of the companiess.

Ｅ．The government should play an important role in controlling pollution.

Ｆ．Today it has more than twenty large factories, which produce many pollutants(污染物)．

Ｇ．The example of Cubatao shows that international companies are not acting in a responsible way either.

 

  It is natural that children are curious about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.

　As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career in science.

　Scientists spend their lives trying to find out about the world. Those who work with the earth sciences study the earth, the oceans, and the sky. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .

　These scientists have already discovered a lot about our world. For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats 65 or 75 times a minute. Your heart is a pump that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too. So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.

　Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.

　We know a lot about our world, but there are still many answers that we do not have, and we are curious.

Mahjong, that favorite pastime of “old folks” in Shanghai, is finding a new audience among younger players, and many university students are becoming mad about this traditional Chinese game. Students at Fudan University have even formed a Mahjong club.

This resurgence of the game, however, is not without its critics. Some people still associate the game with gambling and for many years Mahjong was banned in China. One critic, surnamed Meng, was quoted as saying, “Mahjong is a bad custom that will distract students from studies.” But Yu Guangyuan, former vice-president of the Chinese Academy of Social Sciences(中国社会科学院), says Mahjong is a “healthy, scientific, friendly mind game.”

Mr. Yu’s opinion seems to be shared by the majority of Chinese. They see the game as an activity that requires great concentration and intellectual skill. They also see the game as an important part of Chinese culture and a pastime that brings family and friends closer together. This Spring Festival many families will no doubt spend hours around the Mahjong table getting reacquainted with each other. For them, playing Mahjong is a way of spending quality family time. No one knows who invented Mahjong. Some say it was Confucius, others say the current form of the game was developed right here in Shanghai in the late19th century. It is certainly because of Shanghai that the game enjoys its worldwide popularity. It was brought to America in the 1920s and has since spread throughout Europe and other parts of Asia. There is now a World Championship of Mahjong which is held every year. This year’s championship was held in Chongqing and attracted players from America, Europe and Russia, as well as students from Peking University, Tshinghua University and Nankai University. There was no prize money, but the players delighted in using their wits and their understanding of statistics and probability theory(概率论)to defeat their clever opponents.

Of course, Mahjong doesn’t have to always be that intense. For young people it can be a way to relax and to socialize, a chance to get away from their computers and talk to other people face to face. So, this Spring Festival, why not get out the “old folks” tiles: it’s good to be mad about Mahjong!

B. Because they can win a large amount of prize money.

C. They want to make more friends through Mahjong.
