单选题 Step Back in Time Do you know that we live a lot longer now than the people who were born before us? One hundred years ago the average woman lived to be 45. But now, she can live until at least 80. One of the main reasons for people living longer is that we know how to look after ourselves better. We know which foods are good for U. S. and what we have to eat to make sure our bodies get all the healthy things they need. We know why we sometimes get ill and what to do to get better again. And we know how important it is to do lots of exercise to keep our hearts beating healthily. But in order that we don't slip back into bad habits, let's have a look at what life was like 100 years ago. Families had between 15 and 20 children, although many babies didn't live long. Children suffered from lots of diseases, especially rickets (佝偻病) and scurvy (坏血病), which are both caused by bad diets. This is because many families were very poor and not able to feed their children well. Really poor families who lived in crowded cities like London and Manchester often slept standing up, bending over a piece of string, because there was no room for them to lie down. People didn't have fridges until the 1920s. They kept fresh food cold by storing it on windowsills (窗台板), blocks of ice, or even burying it in the garden. Some children had to start work at the age of seven or eight to earn money for their parents. If you had lived 100 years ago, you might well be selling matchsticks (火柴杆) (a job done by many children)or working with your dad by now.

单选题Freezing to Death for Beauty People in Beijing wear a lot of clothing during winter to fend (抵御) off the cold. In the United States, however, people wear 1 , partly because the car is the primary mode of transportation. Cars take 2 straight to their workplaces, which are heated well. The American diet is full of calories, so the 3 can afford to burn heat more quickly. Fewer layers of clothing give people the opportunity to stay 4 . Lots of Yale girls wear skirts 5 when it"s 10 degrees Centigrade (摄氏温度) outside. Some of them at least wear boots, tights, and leg-warmers. Some, however, really just go for the look 6 the risk of health. These girls have nothing to prevent their legs 7 the wind, and no socks to protect their feet.

单选题 Preserving Nature for Future 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% of reptile (爬行动物) species and 24% of butterflies (蝴蝶) are in danger of 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 (证书) for nature reserves (自然保护区) 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 short sighted view that reserves had to serve immediate human demands for outdoor recreation (户外娱乐) should be replaced by full acceptance of their importance as places to preserve nature for the future. "We forget that they are the guarantee of life systems, on which any built-up area ultimately 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 shrunk (缩小) to become mere islands in a spoiled and highly polluted Landmass."

单选题Happiness A proverb allegedly (据说) from ancient China was widely spread in the West: "If you want to be happy for a few hours, go to get drunk; if you want the happiness to last three years, get married; if you want a lifetime happiness, take up gardening. " The reason for the last option is this: Gardening is not only useful; it helps you to identify yourself with nature, and thus brings you new joy each day besides improving your health. A research of a US university that I"ve read gives a definition of happiness as what makes a person feel comfortably pleased. To put it specifically, happiness is an active state of mind where one thinks one"s life is meaningful, satisfactory and comfortable. This should be something lasting rather than transitory. Lots of people regard it the happiest to be at leisure. But according to the study, it is not a person with plenty of leisure but one at work that feels happy, especially those busy with work having little time for leisure. Happiness does not spell gains one is after but a desire to harvest what one is seeking for. People often do not cherish what they already have but yearn for what they cannot get. That is somewhat like a man indulging in dreams of numerous lovers while reluctant to settle down with the woman beside him. Happiness is a game balancing between two ends—what one has and what one wishes for, i. e. , one"s dream and the possibility to realize it. The study comes to this conclusion: A happy man is one who aims high but never forgets his actual situation; one who meets challenges that tap his ability and potentiality; one who is proud of his achievements and the recognition given to him. He has self-respect and self-confidence; treasures his own identity and loves freedom. He is sociable and enjoys wide-range communication with others; he is helpful and ready to accept assistance. He knows he is able to endure sufferings and frustrations; he is sensible enough to get fun from daily chores. He is a man capable of love and passion.
