KEDS/VANS Slip-on shoes with elastic (弹性的) sides are particularly popular among teenage boys- with Keds and Vans the most sought-after brands. The main problem is that they are just too flat-so flat that the heel, which strikes the ground first, also becomes damaged and painful. | |
BALLET PUMPS The worst shoes of all are such light and thin dolly shoes. The problem is partly their flatness, as with Keds and Vans. However ballet pumps, which have no string or heel, have other specific problems. "As the shoe has no fastening device, it relies on the toes to keep the shoe on, causing an awkward gait (步法), this leads to short- and long-term problems such as calluses (茧子), heel and knee pain." | |
WEDGES AND STILETTOS These shoes can also cause problems with gait. They may look good, but the heels on these are so high they can force the wearer"s body weight forward, making them very unstable. Teens who wear these shoes regularly are also in danger of joining those millions of women with constant back pain. | |

Those who have suffered from insomnia know the sinking feeling of watching the clock tick. Now a new study in the Archives of Internal Medicine suggests that lying in bed awake may actually contribute to the problem of sleeplessness. The study of 79 adults (average age 72) with insomnia aimed to determine whether brief behavioral interventions for insomnia would help. Traditional behavioral therapy (疗法) requires at least half a dozen hour-long sessions with a therapist-a costly commitment many patients either can"t make or don"t have access to. Other options include sleep-aiding medications or supplements. In the current study, the 39 participants in the behavioral therapy group received a 45-to 60-minute instructing session, plus a 30-minute follow-up session and two 20-minute phone calls. Doctors offered the following behavioral interventions for improving sleep: reduce time in bed; get up at the same time every day, regardless of sleep duration; don"t go to bed unless sleepy; and don"t stay in bed unless asleep. The other 40 participants in the study were given printed educational materials about insomnia, which included the same instructions given to the intervention group, but without the individualized sessions with a therapist. Two weeks later, the latter group also got a 10-minute follow-up phone call. At the end of four weeks, the behavioral treatment group was significantly more likely to show improvements in sleep than the printed-materials group. By that time, 55% of those who received behavioral treatment no longer met the criteria for insomnia, compared with 13% of the group that got educational brochures. The good news comes at the same time as a report on the health effects of insomnia from the U.K."s Mental Health Foundation. The report, Sleep Matters, suggests a link between insomnia and poor relationships, low energy levels and an inability to concentrate. Poor sleep has already been linked to depression, immune deficiency and heart disease. | |

Britain"s seed bank, the only one in the world aiming to collect all of the planet"s wild plant species, has reached its goal of banking 10 percent by 2010. The Millennium Seed Bank Project, run by Kew Gardens-one of the oldest botanical gardens-will officially deposit the 24,200th species on Thursday, a pink, wild banana from China. More than 50 countries are now on board with Kew"s giant task but vast places of the globe, including India and Brazil, still need to join in and donate seeds, director Paul Smith said. The seed bank is one of the largest and most diverse in the world with more than 1.5 billion seeds. Its goal is to help protect the planet"s bio-diversity during a time of climate change. The wild banana seed is under threat of extinction (灭绝) in southwest China from agricultural development. It is a vital food source for Asian elephants and important for growing bananas for human consumption. Stored at minus-20 degrees centigrade, so they can last for thousands of years, the seeds await the day that scientists hope never comes-when the species no longer exist in the wild. It is a race against time, Smith said, because in the last decade alone, 20 plants held in the bank have already been wiped out in the wild. He estimates that between a third and a quarter will become extinct this century. "It is urgent and it is happening now. An area, the size of England, is cleared of primary vegetation (植被) every year." Smith said. Because most of the world"s food and medicines come from nature, protecting wild plant species is quite important, scientists say. There are already many other seed banks safeguarding food crops, which only account for 0.6 percent of plant diversity. For Kew"s next goal-to collect a quarter of wild varieties by 2020-the botanists need 10 million pounds a year, or a further 100 million pounds on top of the 40 million they have already been granted. | |

Most people feel lonely sometimes, but it usually only lasts between a few minutes and a few hours. This kind of loneliness is not serious. In fact, it is quite normal. For some people, though, loneliness can last for years. Now researchers say there are three different types of loneliness. The first kind of loneliness is temporary. This is the most common type. It usually disappears quickly and does not require any special, attention. The second kind, situational loneliness, is a natural result of a particular situation, for example, a family problem, the death of a loved one, or moving to a new place. Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year. The third kind of loneliness is the most severe. Unlike the second type, chronic (长期的) loneliness usually lasts more than two years and has no specific cause. People who experience habitual loneliness have problems socializing and becoming close to others. Unfortunately, many chronically lonely people think there is little or nothing they can do to improve their condition. Psychologists agree that one important factor in loneliness is a person"s social contacts, e. g., friends, family members, co-workers, etc. We depend on various people for different reasons. For instance, our families give us emotional support, our parents and teachers give us guidance, and our friends share similar interests and activities. However, psychologists have found that, though lonely people may have many social contacts, they sometimes feel they should have more. They question their own popularity. Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy and unable to socialize and there is a connection between chronic loneliness and serious illness such as heart disease. While temporary and situational loneliness can be a normal, healthy part of life, chronic loneliness can be a very sad, and sometimes dangerous condition. | |

A. Talk to friends. B. Just ignore it. C. Go to see a doctor. D. Ask your teachers for guidance. | |

A. Chronic loneliness can cause family problems. B. Chronic loneliness can cause serious illness. C. Chronic loneliness can not be overcome. D. A, B and C are all correct. | |
