Even if you eat a lot of fast foods, you may still suffer from _____.

Families should sit down and thoroughly discuss the problems involved before buying a dog. [29] Even if the children in your family are the ones who want the dog, the parents are the ones who are really responsible for seeing that the animal is properly cared for. If you don't know much about dogs, it's a good idea to go to the library or the ASPCA for books about various kinds of dogs, as well as books about how to train a puppy. In reading about the different breeds, you should know that a dog described as very alert may be too jumpy and bouncy. When a book describes a dog as an ideal hunting dog, it probably means that the dog won't be happy living in a small apartment. Dog breeds vary in popularity as the years go by. [30] One of the most popular dogs these days is the German shepherd, this is because it provides protection as well as comRanionship. The family should be warned that these dogs grow up to be very big, and may be too powerful for children to handle. If space is limited, a toy dog may be a good choice. There dogs are very small and easy to train. [3] They don't need to be walked daily, since they can exercise in the space available in the home. (33) A．Children. B．Family. C．Parents. D．ASPCA

M: ...and be boxed in by a thousand other houses I suppose~ Surrounded by a thousand faceless neighbors. No, let' s go for the village. After all I'm the one who has to do all the traveling. Back and forth to London every day. And I would rather add a 15 minutes bus ride to the train ride than be--How does it go？--cabin' d, cribb' d confi' d. F: That' s all very well...all very well to take that romantic attitude. You know... you think you can get out of everything...wriggle out of any argument...by quoting Shakespeare. What about my preferences？ You are being selfish you know. M: Selfish？ Me？ F: Yes. Think of the children. Its seems to me that you are so carried away with the idea that your personal likes and dislikes are making you anything but practical. What's the relations between the speakers？ A．Friends. B．Colleagues. C．Husband and wife. D．Landlord and tenant.

Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse's liver genes can be made to behave as they did when the mouse was young simply by limiting its food for four weeks. The genetic rejuvenation won't reverse other damage caused by time for the mouse, but could help its liver metabolize drugs or get rid of toxins. Spindler's team fed three mice a normal diet for their whole lives, and fed another three on half-rations. Three more mice were switched from the normal diet to half-feed for a month when they were 34 months old—equivalent to about 70 human years. The researchers checked the activity of 11,000 genes from the mouse livers, and found that 46 changed with age in the normally fed mice. The changes were associated with things like inflammation and free radical production—probably bad news for mouse health. In the mice that had dieted all their lives, 27 of those 46 genes continued to behave like young genes. But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 percent of these gene changes. "This is the first indication that these effects kick in pretty quickly," says Huber Warner from the National Institute on Aging near Washington, D.C.. No one yet knows if calorie restriction works in people as it does in mice, but Spindler is hopeful. "There's attracting and tempting evidence out there that it will work," he says. If it does work in people, there might be good reasons for rejuvenating the liver. As we get older, our bodies are less efficient at metabolizing drugs, for example. A brief period of time of dieting, says Spindler, could be enough to make sure a drug is effective. But Spindler isn't sure the trade-off is worth it. "The mice get less disease, they live longer, but they're hungry," he says. "Even seeing what a diet does, it's still hard to go to a restaurant and say: 'I can only eat half of that'." Spindler hopes we soon won't need to diet at all. His company, Life Span Genetics in California, is looking for drugs that have the effects of calorie restriction. According to the passage, which of the following is NOT true？ A．Eating less than usual might make us live longer. B．If we go on a diet when old, we may keep healthy. C．Dieting might not be needed. ~ D．We have to begin dieting from childhood.

A．ripe B．mature C．perfect D．far

A stage is actually a box. One side of the box has been removed so the audience can see what's going on inside. The actors remain at a fixed audience. In the film, however, the camera can bring the audience up close and fix their attention on small but important things: a frightened look, a whisper, a trembling of hands. The camera offers the film maker freedom allowing him to move easily across barriers (界限) of time and space. He can show his action in real cities and on real farms. He can also use the camera to change the scene dozens of times in one film. No expert of the stage can do this. The main idea of the text is that______. A．stage plays and films are two different kinds of art B．it is always disappointing to turn play into films C．films have certain advantages over stage plays D．the camera has made film making easy and possible

People may be the most interesting show in a large city. Stroll through busy streets and see what everybody else is doing. You will probably see people from all over the world; you will certainly see people of every age, size, and shape, and you'll get a free fashion show, too. Window—shopping is also a safe sport—is the stores are closed. Check the listings in your neighborhood paper. Local colleges or schools often welcome the public to hear an interesting speaker or a good debate. The film or concert series at the local public library probably won't cost you a penny. Be sure to check commercial ad vertisements too. A flea market can provide hours of pleasant brow sing. Perhaps you can find a free cooking or crafts in a department store. Plan ahead for some activities. It is always more pleasant not to have people in front of you in a museum or at a zoo. You may save some money, too, since these places often set aside one or two free admission days at slow times during the week. (79) Pretend that you are a tourist from time to time, and get to know your city all over a gain including the indispensable (不可错过的) sights that people travel miles to see. If you feel like taking an interesting walk, find a free walking tour, or plan one yourself. You will see your city in a new perspective (视角) once you know more about its history or its architectural treasures. With imagination and a spirit of adventure you can quite easily find good entertainment at no cost at all. Which of the following statements is NOT true？ A．There are many kinds of amusements you can enjoy without spending much money. B．Local colleges often hold meetings to debate the issues people are interested in. C．The film shown at the local public library is often free of charge. D．You should be a tourist if you want to know more about the city you live in.

A．Right B．Wrong C．Not mentioned

Businessmen can travel from London to New York in three hours and lots of people exceed the seventy-mile-per-hour speed limit on motorways. A person of 75 is not old these days. A serious illness does not mean certain death because there have been so many advances in medical science. We no longer need to be afraid of contracting diseases like polio or smallpox. I can speak to my son in Australia from my own sitting room here in Manchester, watch athletes running a race on the other side of the world without moving from my own home and I can even do my shopping while I sit here in an armchair. I never need to worry about food going bad in the warm weather and, at the flick of a switch, I can have a hot meal in a couple of minutes. So, it seems, the quality of life has greatly improved since my own childhood. I'm not convinced, however, that people are happier today than they were 50 years ago. We are certainly materially better off than we were but most people still seem to be weighed down by problems. My daughter and her family are a good illustration. They have a spacious, comfortable home with every labor-saving device you can think of. There's a washing machine, a clothes dryer, a food processor, a vacuum cleaner and all sorts of other household items which are designed to save time but it seems to me that my daughter and her husband just spend all that "saved" time working! They never relax and are always complaining of being tired and "stressed". What is the passage mainly about？ A．How life has improved. B．How life has become worse. C．A comparison of life now and that in the past. D．Memory of life in the past.
