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 plete 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“For the children who consume four or more soft drinks per day, we see more withdrawn behaviors, which make them hard to get along well with others.”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.

(答案→)D
解析：文章叙述了一项研究的结果。一项新的研究发现，经常喝软饮料的儿童，容易出现攻击性行为。研究人员发现，促使儿童出现攻击性行为的主要原因是软饮料中所含的咖啡因。
【小题1】文章出处题：根据第一段“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.”可知，这是一项关于儿童攻击性的研究，A科学技术；B科幻小说；C社会新闻；D健康报道。D项最符合，故选D。
【小题2】细节题：根据“which make them hard to get along well with others”可知，一天喝四杯以上软饮料的儿童，会出现孤僻的行为，他们很难与他人相处好，故选B。
【小题3】细节题：根据第六段“The researchers have determined the link after considering factors like the child’s age and sex. ...the researchers have examined parenting styles”可知，研究人员研究了儿童的年龄、性别和父母的抚养风格，没有提到游戏，故选C。
【小题4】推理题：根据第一、二段和最后一段“over a two-month period ...4 percent of the youngsters have even four or more sodas to drink every day ...Earlier studies of adults have found the highest sugar levels in those”可知，A、B、D错误。根据第三段“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.”可知，饮用软饮料最多的儿童，出现攻击性行为的可能性是不喝软饮料儿童的两倍。不喝软饮料的儿童，出现较少的攻击性行为，故选C。
【小题5】细节题：根据最后一段“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.”可知，caffeine能促使人们感觉精力充沛，能使5岁大的孩子变得更具攻击性。故选C。
