Education enables women to contribute more fully to the social and economic development of their societies. A girl's education is also an investment in future generations. The more educated a mother is, the more likely are her children—particularly her daughters—to roll and stay in school. The higher level of education attained by women is strongly associated with lower child death. Experts believe more educated women practice better hygiene and nutrition(营养),use health services more frequently, and survive better. Woman with more schooling tend to be healthier themselves. Perhaps reflecting their improved ability to avoid frequent childbearing (分娩)and to take advantage of available health services during pregnancy(怀孕). The educational level achieved by women, like family planning services, has the most powerful influence on family size. The impact of education on family size is strongest and most consistent for women who have completed some secondary schooling. Educating girls is three times more likely to lower family size than educating boys. Education appears to affect family size in many ways. More educated women not only want fewer children than their less educated husbands, but also are more likely to use effective contraception(避孕) successfully and to limit their families to the number of children, which contribute to smaller family size. Family size is ideal and child death rates are lowest, therefore, in countries that combine strong family planning and health programs with high levels of education for women.

单选题 Light Night, Dark Stars Thousands of people around the globe step outside to gaze at their night sky. On a clear night, with no clouds, moonlight, or artificial lights to block the view, people can see more than 14,000 stars in the sky, says Dennis Ward, an astronomer with the University Corporation for Atmospheric Research (UCAR) in Boulder, Colo. But when people are surrounded by city lights, he says, they're lucky to see 150 stars. If you've ever driven toward a big city at night and seen its glow from a great distance, you've witnessed light pollution. It occurs when light from streetlights, office buildings, signs, and other sources streams into space and illuminates the night sky. This haze of light makes many stars invisible to people on Earth. Even at night, big cities like New York glow from light pollution, making stargazing difficult. Dust and particles of pollution from factories and industries worsen the effects of light pollution. "If one city has a lot more light pollution than another," Ward says, "that city will suffer the effects of light pollution on a much greater scale." Hazy skies also make it far more difficult for astronomers to do their jobs. Cities are getting larger. Suburbs are growing in once dark, rural areas. Light from all this new development is increasingly obscuring the faint light given off by distant stars. And if scientists can't locate these objects, they can't learn more about them. Light pollution doesn't only affect star visibility. It can harm wildlife too. It's clear that artificial light can attract animals, making them go off course. There's increasing evidence, for example, that migrating birds use sunsets and sunrises to help find their way, says Sydney Gauthreaux Jr., a scientist at Clemson University in South Carolina. "When light occurs at night," he says, "it has a very disruptive influence." Sometimes birds fly into lighted towers, high-rises, and cables from radio and television towers. Experts estimate that millions of birds die this way every year.

单选题Eat for a Good and Healthful Life Food 46 us alive. It is our sustenance and our pleasure. But recently, research has shown that the eating habits of the average Americans may be dangerous to future health. The foods Americans now choose are oftentimes too 47 in calories and fats, so this article reports a new study: Diet and Health, Implications for Reducing Chronic Disease Risk.

Most of us—even those of us at ideal weight—need to eat 53 fat so that no more than 30% of our daily calories will come from fat. That means cutting 54 on red meat and whole milk dairy products. 55 , eat fish, chicken without skin, lean meats, and low-fat and no-fat dairy products. The report of the Committee on Diet and Health recommends we eat five or more 1/2-cup servings of vegetables and fruits 56 —especially green and yellow vegetables and citrus fruits. Eating more fruits and vegetables doesn"t have to mean increased calories intake. Many plant foods are nutrient-rich: they provide many vitamins and minerals for very few 57 . Nutrient-rich foods are particularly important for Americans 58 50-year-old. As we 59 , we need to eat less because our bodies need 60 calories to function properly.

单选题Priscilla Ouchida's "energy efficient" house turned out to be a horrible dream. When she and her engineer husband married a few years ago, they built a $100,000, three-bedroom home in California. Tightly sealed to prevent air leaks, the house was equipped with small double paned (双层玻璃的) windows and several other energy saving features. Problems began as soon as the couple moved in, however. Priscilla's eyes burned. Her throat was constantly dry. She suffered from headaches and could hardly sleep. It was as though she had suddenly developed a strange illness. Experts finally traced the cause of her illness. The level of formaldehyde (甲醛) gas in her kitchen was twice the maximum allowed by federal standards for chemical workers. The source of the gas? Her new kitchen cabinets and wall to wall carpeting. The Ouchidas are victims of indoor air pollution, which is not given sufficient attention partly because of the nation's drive to save energy. The problem itself isn't new. "The indoor environment was dirty long before energy conservation came along. " says Moschandreas, a pollution scientist at Geomet Technologies in Maryland. "Energy conservation has tended to accentuate the situation in some cases. " The problem appears to be more troublesome in newly constructed homes rather than old ones. Back in the days when energy was cheap, home builders didn't worry much about unsealed cracks. Because of such leaks, the air in an average home was replaced by fresh outdoor air about once an hour. As a result, the pollutants generated in most households seldom built up to dangerous levels.
