   As people slowly learn to cure diseases, control floods, prevent hunger, and stop wars, fewer people die every year. As a result, the population of the world is becoming larger. In 1925 there were about 2 billion people in the world; today there are over 6 billion.

   When the number rises, extra mouths must be fed. New lands must be brought under development, or land already farmed must be made to produce more crops. In some areas the land is so over-developed that it will be difficult to make it provide more crops. In some areas the population is so large that the land is divided into too tiny units to make improvement possible with farming methods. If a large part of this farming population went into industrial work, the land might be farmed much more productively (多产地) with modern methods.

    There is now a race for science, technology, and industry to keep the output of food rising faster than the number of people to be fed. New types of crops, which will grow well in bad weather, are being developed, so there are now farms beyond the Arctic Circle in Siberia and North America. Irrigation (灌溉) and dry-farming methods bring poor lands under the plough. Dams hold back the waters of great rivers, which can provide water for the fields in all seasons and provide electric power for new industries. Industrial chemistry provides fertilizer to suit different soils. Every year, some new methods are made to increase or to protect the food of the world.

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 organisms（生物体）to be affected are either plants or plankton(浮游生物). 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’s not until dead fish and water birds are seen at the river’s edge or on the seashore that people realize what is happening.

　　Where do the substances which pollute the water come from? There are two main sources of sewage（下水道污物）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 water-proof (防水). 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 as there are many highly poisonous things in it, such as copper and lead.

　　So, if we want to stop this pollution, the answer is simple: sewage and industrial waste must be made clear 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.

70. Pollution of water is noticed________.

　　A. when the first organisms are affected　     

B. when a good many fish and birds die

　　C. when poisonous things are poured into water　

D. as soon as the balance of nature is destroyed

71.The living things die because there is no ________in the lake or river.

　　A. water　　　　　            B. fish            　 C. poison　　　　　   D. oxygen

72. Which of the following is harmful according to the passage?

　　A. Organisms               　B. Plants and plankton in the water

　　C. Waste water from cleaning    D. Industrial waste made clear before flowing into the water

73. The way to stop water pollution is to________.

　　A. realize the serious situation clearly

　　B. put oxygen into the river

　　C. make the waste material harmless before flowing into the water

　　D. make special room in the sea for our rubbish

As the pace of life continues to increase, we are fast losing the art of relaxation. Once you are in the habit of rushing through lift, being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body.                              

Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health.                                                

The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme, but however little the stress is, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Such serious conditions as high blood pressure and heart disease have established links with stress. Since we cannot remove stress from our lives (it would be unwise to do so even if we could), we need to find ways to deal with it.                                                               

People are finding less and less time for relaxing themselves because_____.                                                  

A. they do not know how to enjoy themselves                                       

B. they do not believe that relaxation is important for health      C. they are travelling fast all the time                                                    

D. they are becoming busier with their work  

According to the writer, the most important character for a good manager is his ________.   

A. not fearing stress                                                  B. knowing the art of relaxation         

C. high sense of responsibility                                   D. having control over performance   

Which of the following statements is true?  

A. We can find some ways to avoid stress. 

B. Stress is always harmful to people. 

C. It is easy to change the habit of keeping oneself busy with work.  

D. Different people can withstand different amounts of stress.  

In Paragraph 3, "such a reaction" refers back to_______. 

A. "making a choice between 'flight' or 'fight'"                                                         

B. "reaction to stress both chemically and physically"                                                      

C. "responding to crises quickly"

D. "losing heart at the signs difficulties" 

In the last sentence of the passage, "do so " refers to ______.     

A. "expose ourselves to stress"                               

B. "find ways to deal with stress" 

C. "remove stress from our lives"                   

D. "established links between diseases and stress"

A recent survey of teachers found that an unhealthy passion with celebrity culture is having a negative impact on British students’ studies and it discovered that celebrity couple, the Beckhams, are the favorites among most students. Many students are ignoring building their own careers to seek a chance at fame instead, the Association of Teachers and Lecturers (ATL) survey found.

Almost two-thirds of teachers said sports stars were the type of celebrity many pupils wanted to follow while more than half of students wanted to be pop stars.

The survey said the celebrities that students aspired to mostly were David and Victoria Beckham who live in Los Angeles now. Soccer player Beckham is on the top of the survey while in second place, with almost a third of the survey’s votes, was his 33-year-old pop star wife.

Almost half of the 300 teachers surveyed said pupils tried to look like or behave like the celebrities they most admired, with some girls even dressing "unsuitably".

"We are not surprised about the influence of celebrity culture in schools —it reflects the current media passion with celebrities and the effect of celebrity culture on society as a whole," ATL general secretary Mary Bousted said in a statement.

"Celebrities can have a positive effect on pupils. They can raise pupils’ aspirations and desires for the future. However, celebrity culture can spread the idea that celebrity status is the greatest achievement and reinforce the belief that other career choices are not as valuable," said one primary school teacher. "Too many of the pupils believe that school success is unnecessary, because they will be able to get fame and fortune quite easily through a reality TV show."
