Apparently，we are safe neither at home nor in the business office.We use water in both places，but the research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted side effects.These chemicals can cause potential harm through drinking and in seemingly harmless activities as cleaning one’s house.They are released(set free)from water by daily actions like water running out of tap，spraying from garden pipes，or splashing in dishwashers and washing machines.As the water is moving.these chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health.

　　Does this mean we should stop bathing? No, say the scientists, but we should put all pollution into perspective. Activities at home such as the burning of coal, cooking oil, or even candles release carbon monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or living near heavy traffic. New tugs, bedding, and even clothing give off that“new smell, ”which is a sure sign of chemicals. In the office, newly applied paint, newly purchased telephones and other telecommunications equipment, and computers release polluting chemicals, too. As offices and homes often have inadequate ventilation (通风), these chemicals can build up to become health problems. Their poisonous effects are only now being slowly recognized.

　　These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical smell is a wise warning. Home and office windows should be opened during good weather. Even one’s car needs to be ventilated as well while in the garage.

　　We need further research to understand better other potential health dangers, too. For example, the effects of overcrowding of schools (carbon dioxide build-up ), the factory work environment ( an endless list of potentially dangerous substances ), and even home heating and cooling (the air conditioner may be our enemies, not our friends) have only recently started to come to light. Until we understand the effects of our new technological environment better, we can only hope that“there is no place like home.”

　　As the country's economy continues to steam ahead,once popular forms of entertainment,such as Karaoke(卡拉OK),card games and even boxing bars,appear to be losting their attractiveness.Stressed out white - collar wokers are camping out on rooftops,smashing(砸）up restaurants,pretending to be children and even visiting cemeteries in a effort to ease the pressure of modern life.

　　Consider the members of Shanghai's Cat Rain club.By day,this group of young women work executive (决策管理的) jobs,but by night they climb buildings so they can spend the night on the roof."You feel relaxed when you're sitting on the roof,looking up to the sky and chatting with friends," said Gong Ying,25.

　　The stress of work is not just limited to people in Shanghai.A recently opened restaurant in Beijing encourages customers(顾客) to smash plates --- as long as they are willing to pay to replace them.Some workers even wish to return to their childhoods.Recently,hundreds of people took part in a festival in which adults pretended to be children.It was an adultsonly event,and participants could read comics and eat sweets all day.

　　Scenic places such as parks and rivers can also help people relax and put things in perspective.But a cemetery?

　　Cemetery companies in Shanghai organized visits to local graveyards for stressed - out workers in March.The participants were taken to quiet spots in the cemetery where they could think about life and their futures."Pressure may bring us unhappiness,but it doesn't mean we can't find ways out,"says Chen Bin,a rooftop camping fan with still some other interests."Life should be imaginative."

　Demands for stronger protection for wildlife in Britain sometimes hide the fact that similar needs are felt in the rest of Europe. Studies by the Council of Europe, of which 21 countries are members, have shown that 45 per cent of reptile (爬行动物) species and 24 per cent of butterflies are in danger or dying out.

　　European concern for wildlife was outlined by Dr Peter Baum, an expert in the environment and natural resources division of the council, when he spoke at a conference arranged by the administrators of a British national park. The park is one of the few areas in Europe to hold the council’s diploma for nature reserves of the highest quality, and Dr Baum had come to present it to the park once again. He was afraid that public opinion was turning against national parks, and that those set up in the 1960s and 1970s could not be set up today. But Dr Baum clearly remained a strong supporter of the view that natural environments needed to be allowed to survive in peace in their own right.

　　“No area could be expected to survive both as a true nature reserve and as a tourist attraction,” he went on. The shortsighted view that reserves had to serve immediate human demands for outdoor recreation should be replaced by full acceptance of their importance as places to preserve nature for the future.

　　“We forget that they are the guarantee (保证) of life systems, on which any built-up area depends,” Dr Baum went on. “We could manage without most industrial products, but we could not manage without nature. However, our natural environment areas, which are the original parts of our countryside, have become mere islands in a spoiled and highly polluted land.”

59. Recent studies by the Council of Europe have declared that ____ .

　A. wildlife needs more protection only in Britain

　B. all species of wildlife in Europe are in danger of dying out

　C. there are fewer species of reptiles and butterflies in Europe than elsewhere

　D. many species of reptiles and butterflies in Europe need protecting

60. Why did Dr Baum come to a British national park?

　A. Because he needed to present it with a council's diploma.

　B. Because he was concerned about its management.

　C. Because it was the only national park of its kind in Europe.

　D. Because it was the only park that had ever received a diploma from the council.

61. The last sentence in the second paragraph implies that ____ .

　A. people should make every effort to create more environment areas

　B. people would go on protecting national parks

　C. certain areas of the countryside should be left intact (完整的)

　D. people would defend the right to develop the areas around national parks

62.Which of the following can be inferred from the last paragraph?

　A. We have developed industry at the expense of countryside.

　B. We have forgotten what our original countryside looked like.

　C. People living on islands should protect natural resources for their survival.

One morning a few years ago，Harvard President Neil Rudenstine overslept. For this busy man，it was a sort of alarm: after years of non-stop hard work，he might wear himself out and die an early death.

Only after a week's leave—during which he read novels, listened to music and walked with his wife on a beach—was Rudenstine able to return to work.

In our modern life, we have lost the rhythm between action and rest. Surprisingly, within this world there is a universal but silly saying:“I am so busy.”

We say this to one another as if our tireless efforts were a talent by nature and an ability to successfully deal with stress. The busier we are, the more important we seem to ourselves and, we imagine, to others. To be unavailable to our friends and family, and to be unable to find time to relax—this has become the model of a successful life.

Because we do not rest, we lose our way. We miss the guide telling us where to go, the food providing us with strength, the quiet giving us wisdom.

How have we allowed this to happen? I believe it is this: we have forgotten the Sabbath, the day of the week—for followers of some religions—for rest and praying. It is a day when we are not supposed to work, a time when we devote ourselves to enjoying and celebrating what is beautiful. It is a good time to bless our children and loved ones, give thanks, share meals，walk and sleep. It is a time for us to take a rest, to put our work aside, trusting that there are larger forces at work taking care of the world.

Rest is a spiritual and biological need；however，in our strong ambition to be successful and care for our many responsibilities，we may feel terribly guilty when we take time to rest. The Sabbath gives us permission to stop work. In fact, “Remember the Sabbath ”is more than simply permission to rest；it is a rule to obey and a principle to follow.

50. The “alarm” in the first paragraph refers to “______”.

　　A. a signal of stress                                   B. a warning of danger

　　C. a sign of age                                       D. a spread of disease

51. According to Paragraph 4,a successful person is one who is believed to ____.

　　A. be able to work without stress　　            B. be more talented than other people

　　C. be more important than anyone else　　 D. be busy working without time to rest

52. Some people feel guilty when taking time to rest because they ____.

　　A. think that taking a rest means lacking ambitions

　　B. fail to realize that rest is an essential part of life

　　C. fail to realize that religions force them to rest

　　D. think that taking a rest means being lazy

53. What is the main idea of this passage?

　　A. We should balance work with rest.

　　B. The Sabbath givers us permission to rest.

　　C. It is silly for anyone to say “I am so busy.”

　　D. We should be available to our family and friends.
