| An Ohio State University study has
linked behavior in young children with the type of job their mother has. Mothers
with complex occupations that are self-directed and require working with other
people tended to have offspring with relatively low levels of behavior problems.
The opposite held true when the jobs were routine, closely supervised, and dealt
with things, rather than people. "A job that challenges and interests a mother and gives her an opportunity to exercise judgment and solve problems clearly has positive consequences for her children’s behavior," indicates associate professor of sociology Elizabeth Menaghan. Occupations with more positive conditions include management, sales, and teaching positions. Jobs that may be related to increased child behavior problems include book-keeping, food service, and assembly lin A. Less controlled mothers at work rely much on physical punishment. B. The frequency of behavior problems in children is determined by mothers. C. Parents with challenging jobs give their children better home environment. D. Children are encouraged to follow parental demands even when they aren’t being supervised. [单项选择]目前啤酒过滤的方法中使用最普遍的是（）。

His dream began in the first grade when he learned that people were dying because they didn't have clean water,and that as little as $70 could build a well."We really take water for granted,"says Ryan,of Kemptville,Ontario,in Canada."In other countries,you have to plan for it." Ryan earned the first $70 by doing extra chores（零工）,but with the help of others, he has since raised hundreds of thousands of dollars.His efforts led to the start of the Ryan's Well Foundation,which raises money for clean water and health-related services for people in African countries and developing countries.
