B Some parents will buy any high-tech toy if they think it will help their child, but researchers said puzzles help children with math-related skills. Psychologist Susan Levine, an expert on mathematics development in young children the University of Chicago, found children who play with puzzles between ages 2 and 4 later develop better spatial skills. Puzzle play was found to be a significant predictor of cognition (认知) after controlling for differences in parents' income, education and the amount of parent talk, Levine said. The researchers analyzed video recordings of 53 child-parent pairs during everyday activities at home and found children who play with puzzles between 26 and 46 months of age have better spatial skills when assessed at 54 months of age. "The children who played with puzzles performed better than those who did not, on tasks that assessed their ability to rotate (旋转) and translate shapes," Levine said in a statement. The parents were asked to interact with their children as they normally would, and about half of children in the study played with puzzles at one time. Higher-income parents tended to have children play with puzzles more frequently, and both boys and girls who played with puzzles had better spatial skills. However, boys tended to play with more complex puzzles than girls, and the parents of boys provided more spatial language and were more active during puzzle play than parents of girls. The findings were published in the journal Developmental Science.1.

Simply increasing physical activity levels alone is unlikely to reduce body weight in young children, and therefore will probably not prevent obesity (肥胖), although it may set the stage for a healthier lifestyle, the results of a study conducted in Scotland suggest. Instead, a combination of increased physical activity and other lifestyle changes like sticking to a healthy diet may be needed to stop the trend of obesity. “Many children are obese, even at preschool age,” Dr John J. Reilly from the University of Glasgow and his colleagues note in the British Medical Journal. Considering the general lack of evidence on proper ways to prevent obesity in this age group, Reilly’s team had 545 children from 36 nursery schools in the “Movement and Activity Glasgow Intervention (干预) in Children” or MAGIC trial. The trial was specifically designed to see if an increase in activity could reduce body mass index (身体质量指数). Each week for 24 weeks roughly half of the preschoolers, who were an average of 4.2 years old, participated in three 30-minute active workouts while at nursery school and their parents were encouraged to increase the child’s activity levels at home. The other half of the children, serving as contrasts, followed their usual nursery school schedule. According to the researchers, the physical activity intervention had no significant effect on body mass index of the children. However, compared with contrast children, intervention children show greater gains in body movement skills, which, the researchers say, may increase confidence in physical ability, perhaps increasing the opportunities of future participation in physical activity or sports. In a word, Reilly and his colleagues suggest that “successful interventions to prevent obesity in early childhood may require changes not just at nursery, school, and home, but in the wider environment. Changes in other behaviors, including diet, may also be necessary.” (1) (2) (3) (4) (5) (6) (7) (8) (9)

Of many problems in the world today, none is as widespread, or as old, as crime. Crime has many forms, including crimes against property, person, and government. Crime, in all its forms, penetrates every layer of society and touches every human being. You may never have been robbed, but you suffer the increased cost of store-bought items because of other’s shoplifting and you pay higher taxes because of other’s tax evasion. Perhaps your house is not worth as much today as it was a few years ago because of the increased crime rate in your neighborhood, or maybe your business is not doing as well as it used to because tourism is down due to increased terrorism in your part of the world. Whatever you do, wherever you go, you are a victim of crime whether you like it or not, whether you know it or not. Crime, especially violent crime, has risen to a point where many people are afraid to walk alone in their own neighborhoods, afraid to open their door after dark. Expert argues whether the number of crimes committed is actually on the rise. This issue is particularly true in eases of family violence, the abuse of husbands, wives or children. Throughout much of history, eases of family violence and neglect often went unreported because of the attitude of society, which considered family matters to be private.It can be inferred from the passage that（） A. cases of family violence are on the riseB. there have been more cases of family violence than those recordedC. cases of family violence are fewer than those of other crimesD. victims of family violence don’t report for fear of losing face
