Xia’s death is warning to other students. A new rule went into effect on January 1, 2006. Teens are not allowed to buy or drink alcohol. Shops are not allowed to sell it to them.
A 1999 Chinese law forbade (禁止) shops to sell alcohol to youths under 18. But it is not taken seriously by shopkeepers because it doesn’t have specific rules. People hope the new rule will work.
“I tasted alcohol when having the dinner of the last New Year’s Eve,” said Lian Yuqi, a 16-year-old girl in Xiamen. She believes that the new rule will stop teens from drinking and help them grow in a healthy way.
“Although it may be a little disappointing not to have beer at parties, I think we can have soft drinks instead,” she said.

Education is discovering about ourselves and about the people and things around us. All the people who care about us — our parents, brothers, sisters, friends — are our teachers. In fact, we learn something from everyone we meet. We start learning on the day we are born, not on the first day" we go to school. Every day we have new experiences, like finding a bird"s nest, discovering a new street in our neighborhood, making friends with someone we didn"t like before. New experiences are even more fun when we share them with other people.
Encouragement from the people around us enables us to explore things as much as possible. As we grow up, we begin to find out what we are capable of doing. You may be good at cooking, or singing or playing football. You find this out by doing these things. Just thinking about cooking doesn"t tell you if you are good at it.
We learn so much just living from day to day. So why is school important? Of course you can learn some things better at home than at school, like how to do the shopping, and how to help old or disabled people who can" t do everything for themselves. At school, teachers help us to read and write. With their guidance, we begin to see things in different ways.

olve more and more complex chemical processes will produce larger volumes of liquid wastes, and many of these will contain chemicals which are noxious. To feed our rapidly expanding population, agriculture wil
l have to be intensified. This will involve ever - increasing quantities of agricultural chemicals. From this, it is apparent that drastic steps must be taken immediately to develop corrective measures for the pollution problem. There are two ways by which this pollution problem can be dwindled(减少). The first relates to the treatment of wastes to decrease their pollution hazard . This involves the processing of solid wastes "prior to" disposal and the treatment of liquid wastes, or effluents, to permit the reuse of the water or minimize pollution upon final disposal .
A second approach is to develop an economic use for all or a part of the wastes. Farm manure is spread in fields as a nutrient or organic supplement. Effluents from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained. Effluents from other processing plants may also be used as a supplemental source of water. Many industries, such as meat and poultry processing plants, are currently converting former waste products into marketable byproducts. Other industries are potential economic uses for waste products.
小题1:The purpose of this passage is ________.
| A．to alert the reader to the dwindling water supply |
B．to explain industrial uses of water |
| C．to acquaint the reader with water pollution problems |
| D．to demonstrate various measures to solve the pollution problem |
| A．Industrial development includes the simplification of complex chemical processes. |
| B．Diluting wastes needs certain amount of water. |
| C．Demands for water will go up along with the expanding population . |
| D．Intensive cultivation of land require more and more chemicals. |
| A．countries of the world will work together on pollution problems |
| B．byproducts from wastes lead to a more prosperous marketplace |
| C．science is making great progress in increasing water supplies |
| D．some industries are now making economic use of wastes |
| A．interviews with authorities in the field of water controls |
| B．opinions and personal observations |
| C．definitions which clarify important terms |
| D．strong arguments and persuasions |
| A．after | B．during | C．before | D．beyond |
Professor John Anthony Allan of the University of London in Britain won the award for introducing the idea of “virtual water (虚拟水)”, a calculation method that has changed the nature of trade policy and research.
Allan has written seven books and published more than 100 papers.
The Stockholm International Water Institute said this idea is now embedded (埋藏) in the production of foods and industrial products. The institute said Allan’s work had made a big effect on global trade policy and research, especially in water-scarce (缺水的) regions.
“The improved understanding of trade and water management issues on local, regional and global scales are of the highest value for the successful and sustainable (可持续的) use of water resources,” it said.
“People do not only use water when they drink it or take a shower,” the institute said. “Behind the morning cup of coffee, there are 140 liters of water that was used to grow, produce, package and ship the beans.” That is about as much water as a person in England uses on average for all daily drinking and household needs.
“For a single hamburger, about 2,400 liters of water are needed. In the USA, the average person uses nearly 7,000 liters of virtual water every day.” It said that was more than three times the average use of a Chinese person.
小题1:Allan was awarded the prize because _______.
| A．he wrote seven books on trade policy |
| B．he published more than 100 papers on water management |
| C．he found a new kind of water in water-scarce areas |
| D．he came up with the idea of virtual water |
| A．The average American uses about 7,000 liters of water a day. |
| B．The average Chinese uses nearly 2,300 liters of virtual water a day. |
| C．An Englishman usually drinks about 140 liters of coffee a day. |
| D．A hamburger usually contains about 2,400 liters of water. |
A. He won the 2008 Nobel Prize. B. He has written over 100 books
.C. He works at the University of London. D. He lives in the USA.
小题4:What effect does the idea of virtual water have?
| A．It helps us realize the importance of trade. |
| B．It helps people do successful business. |
| C．It helps us make use of water scientifically. |
| D．It tells us how much water we use a day. |
Less than 10 years ago I drove to a thinly populated section of my town, lay down in the middle of the road and watched an attracted meteor shower(流星雨). The area was short of homes, street lights and traffic. If I did that today, I wouldn’t be able to see the meteor shower as well, and I would surely be run over by a car.
Nowadays scientists are finding light pollution can be almost as bad as carbon dioxide pollution. If you’ve ever taken a flight at night, the view is beautiful, but you must remember that all the light you see is wasted electricity. The crew of the space shuttles see an even bigger picture of ho
w extensive the wasted electricity is worldwide.Additionally, electricity needs to be generated, and the generation of electricity creates pollution by giving off greenhouse gases. This affects the air we breathe and our quality of life.
Scientists are also studying the effects of light pollution on wildlife. Thousands of birds die each year when they crash into highly lighted buildings, as they become puzzled by the light. It has been long known that tiny sea turtle hatchlings become lost and follow lights on the shore instead of heading towards the sea.
Fortunately, light pollution is one of the easiest sources of pollution that can be corrected without a negative effect. Following some guidelines and a little searching on Google can give you many ideas on how to reduce your contribution to light pollution.
小题1:The author tells the story in the second paragraph mainly to _________.
| A．remember the past beauty of the town. |
| B．stress the advantages of less pollution |
| C．show the great changes of the town |
D．prove the bad effects of li ght pollution |
| A．to try to reduce unnecessary light. |
| B．not to ignore the beauty around. |
| C．to set proper light for animals |
| D．not to destroy the animal’s living conditions. |
| A．Light pollution is difficult to deal with. |
| B．Light pollution is a threat to some animals. |
| C．Light pollution has nothing to do with global warming |
| D．Astronauts can’t see clearly in space due to light pollution. |
agraph?| A．The author’s contribution to light pollution |
| B．Other sources of light pollution |
| C．Ways of reducing light pollution |
| D．More bad effects of light pollution |
