中国社会科学院2009年6月15日上午举行了2009年中国城市发展高峰论坛暨《城市蓝皮书》发布会。中国社会科学院城市发展与环境研究中心副主任魏后凯指出，从去年的情况来看，中国的城乡收入差距依然比较大，城乡收入比值为3.31。从每百户家用电脑拥有量来看，去年城镇地区达到59.3台，比农村地区高10倍左右。如此大的收入差距，必然会影响我国的社会稳定和经济的发展，因此解决这一问题，实现社会公平是党和国家的重要任务。 根据上述材料回A new study has found evidence of aggressive (攻击性的) behavior in children who drink four or more servings of soft drinks every day. Information for the study came from the mothers of 3,000 5-year-olds. Researchers asked the women to keep a record of how many servings of soft drinks their children drank over a two-month period. They were also asked to complete a checklist of their children’s behavior. The researchers have found that 43 percent of the children drink at least one daily serving of soda, and 4 percent of the youngsters have even four or more sodas to drink every day. Shakira Suglia, a famous expert, says they’ve found that children who drink the most soda are more than twice as likely as those who drink no soda to show signs of aggression. “For the children who consume four or more soft drinks per day, we see more withdrawn behaviors, which make them hard to get along well with others.” The aggressive behaviors include destroying possessions belonging to others, taking part in fights and physically attacking people. The researchers have determined the link after considering factors like the child’s age and sex. They have also considered other possible influence, such as whether the boys and girls are eating sweets or giving fruit drinks on a normal day. In addition, the researchers have examined parenting styles and other social conditions that may be taking place in the home. Researches are trying to find why young children who drink a lot of soda have behavior problems. An ingredient often found in soft drinks is caffeine, which helps to make people feel energetic. Doctor Suglia suggests that caffeine could cause the 5-year-olds to be more aggressive. Earlier studies of adults have found the highest sugar levels in those who carry weapons (武器) and show signs of negative social behavior.【小题1】What section of a newspaper is the passage probably taken from?A．Scientific TechnologyB．Science FictionsC．Social NewsD．Health Report【小题2】The underlined word “withdrawn” in paragraph 4 can probably be replaced by the word ______.A．backwardB．unsocialC．generousD．friendly【小题3】Researchers studied the following aspects of the children except ______.A．ageB．sexC．gamesD．parents【小题4】According to the research, which of the following is right?A．Mothers were asked to keep a record of how many servings of soft drinks their children drank over a three-month period.B．4 percent of the youngsters have even four or fewer sodas to drink every day.C．Children who drink no soda show fewer aggressive behaviors.D．Children with the highest sugar levels tend to carry weapons and show signs of negative social behavior.【小题5】After a further study on ingredients in soda, Shakira Suglia implies that the direct cause of the aggressive behaviors may be ______.A．soft drinksB．attention problems C．caffeineD．social conditions
