As a result of pollution , Lake Erie , on the borders of the USA and Canada, is now without any living things.　　
Pollution in water is not simply a matter of “poisons” killing large numbers of fish overnight. Very often the effects of pollution are not noticed for many months or years because the first organism(生物体 ) to be affected are either plants or plankton. But these organisms are the food of fish and birds and other creatures. When this food disappears, the fish and birds die too. In this way a whole food chain can be wiped out, and it is not until dead fish and water birds are seen at the river’s edge or on the sea shore that people realize what is happening.　　
Where do the substances which pollute the water come form? There are two main sources sewage (污水) and industrial waste. As more detergent (洗涤剂 ) is used in the home, so more of it is finally put into our rivers. lakes and seas. Detergents harm water birds dissolving the natural substances which keep their feathers waterproof. Sewage itself, if not properly treated, makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen they need. Industrial waste is even more harmful since there are many highly poisonous things in it, such as copper and lead(铅 ).　　
So , if we want or stop this pollution , the answer is simple: sewage and industrial waste must be made clean before flowing into the water. It may already be too late to save some rivers and lakes, but others can still be saved if the correct action is taken at once.

If you are asked to name some national emblems of China, the dragon will probably be one of the famous images that pop into your head. We Chinese often consider ourselves "the descendants（后代）of the dragon." It is not unfamiliar to you that your parents hope that you "may become the dragon".  

　　As a mythical（神秘的）creature, the dragon is deeply rooted in Chinese culture. Traditionally, dragons are considered to govern rainfall. They have the power to decide where and when the rain falls. In addition, the dragon is a symbol of imperial （帝王的）power. The emperors thought they were real dragons and the sons of the heaven.  　

But the creature is regarded differently in Western countries. In the Bible, dragons represent the devil（恶人）. Western people usually see dragons as cold-blooded reptiles（爬虫）, like snakes and cruel killers. In their eyes, dragons are also dishonest.　　

　　Dragons in Western literature are presented as monsters（怪物）. It is a common tale for a mediaeval knight（中世纪的骑士） to kill a dragon and save a princess and her country from its evil. Even the popular boy wizard Harry Potter has to battle against a dragon.  　　

　　However, dragons are not all bad in the West. "Puff the Magic Dragon" is a well-known song. The lyrics(歌词) tell a bitter-sweet story of the dragon Puff and his playmate Jackie Paper, a little boy. When Jackie grows up, he loses interest in the imaginary adventures of childhood and leaves Puff upset. Puff represents the innocence of a child's imagination, which is very positive for a dragon.  　　

1.The underlined word” emblems” in the first paragraph means “_______”.

2.What is a dragon presented as according to Western literature?

A wizard      B. A mediaeval knight  C. A princess           D. A monster

3.The writer gave the example of “ Puff the Magic Dragon” to show_____.

　The dream of flying into outer space, cherished by the Chinese people for centuries, will soon come true.

　　China launched its fourth unmanned spacecraft （飞船）“Shenzhou Ⅳ” on December 30 at the Jiuquan Satellite Launch Centre in Gansu Province. It was the 27th consecutive（连续的 ）and successful launch of China - made rockets since October 1996. This launch has made it more realistic for China to send a person into space on its own following Russia and the USA.

　　Qi Faren，leading designer of the spacecraft system, said all the functions （功能） designed for manned flights have withstood （经受住）the test of three previous, successful launches and return landings of the “Shenzhou” spaceships.

　　China launched the “Shenzhou Ⅰ ”, “Shenzhou Ⅱ ”and “Shenzhou Ⅲ ”spacecrafts in 1999,2001 and 2002 respectively.

　　“Shouzhou Ⅳ” was to make it a more comfortable place in which astronauts can live and work. All parts of the application system for manned flight are aboard the “Shenzhou Ⅳ”craft in all test flights.

　　China’s manned flight programme began in 1992. A number of unmanned test flights will be launched before Chinese astronauts are sent into space.

　　Leading scientists in charge of China’s manned space programme said the successful launch of the “Shenzhou Ⅳ” laid a solid foundation for the country’s future task of sending Chinese astronauts to outer space.

　　The spacecraft returned to the earth on January 5, after completing seven experiments in space.
