A new study suggests that the round­the­clock availability that cell phones have brought to people's lives may take a toll on family life. The study，which followed more than 1,300 adults over 2 years, found that those who consistently used a mobile phone throughout the study period were more likely to report negative “spillover” between work and home life—and，in turn，less satisfaction with their family life.

Spillover essentially(本质上)means that the line between work and home begins to become unclear. Work life may invade home life when a parent is taking job­related calls at home，for instance—or family issues may start to take up work time. For example，a child may call mum at work，telling her “microwave exploded”，explained Noelle Chesley，an assistant professor of sociology at the University of Wisconsin­Milwaukee and the author of the study. The problem with cell phones seems to be that they are allowing for even more spillover between work and home.

This may be especially true for working women，the study found. Among men，consistent use of mobile phones seemed to allow more work issues to creep (潜入)into family time. But for women，the spillover tended to go in both directions. Being “connected” meant that work cut into home time，and family issues came into work life.

Cell phones seem to be opening more lines for stressful exchanges among family members. But there may be ways to control the spillover，according to Chesley. Employers, she said，could look at their policies on contacting employees after hours to make sure their expectations are “reasonable”．For their part，employees could decide that cell phones go off during family time, Chesley said.

4.What is the main idea of the passage?

For much of the world, vegetarianism (素食主义) is largely a matter of economics: Meat costs a lot more than beans or rice, so meat becomes a special-occasion dish. Even where meat is more plentiful, it’s still used in control, and it often provides a side note to a meal rather than taking center stage.
In countries like the United States where meat is not as expensive, though, people choose to be vegetarians for reasons other than cost. Parental preferences(父母亲的偏爱), religious or other beliefs, and health problems are among the most common reasons for choosing to be a vegetarian. Many people choose a vegetarian diet out of concern over animal rights or the environment. And lots of people have more than one reason for choosing vegetarianism.
Different people follow different forms of vegetarianism. A true vegetarian eats no meat at all, including chicken and fish. A lactoovo(乳制品)  vegetarian eats dairy products  and eggs, but keeps out meat, fish, and chicken. It follows, then, that a lacto(乳，乳汁) vegetarian eats dairy products but not eggs, and an ovo （蛋，鸡蛋） vegetarian eats eggs but not dairy products.
A stricter form of vegetarianism is veganism. Not only are eggs and dairy products excluded (排除) from a vegan diet, so are animal products like honey. Some macrobiotic (养生的) diets fall into the vegan category. Macrobiotic diets limit not only animal products but also refined（经过提炼的） and processed foods, foods with preservatives, and foods that contain caffeine or other stimulants (刺激物).
Following a macrobiotic or vegan diet could lead to nutritional deficiencies (营养不足) in some people. Teens need to be sure their diets include enough nutrients to fuel growth, particularly protein and calcium (钙). If you’re interested in following a vegan or macrobiotic diet it’s a good idea to talk to a registered dietitian（营养学家）. He or she can help you design meal plans that include enough nutrients.
