[1]A new study has found evidence of aggressive behaVior in children who drink four or more servings of soft drinks every day．
[2]The mothers of 3，000 five-year-olds took part in the study．They were asked to keep a record of how many servings of soft drinks their children drank over a two-month period and keep records of how they behaved．The researchers found that 43 percent of the boys and girls drank at least one daily serving of soda．Four percent of the youngsters had four or more sodas to drink every day．
[3]Children who drank the most soda were more than two times likely to show signs of aggression．“For the children who consumed four or more  soft drinks per day，we see an association between aggressive behaviors, attention problems and withdrawn behaviors．”Shakira Suglia says．The aggressive behaviors included destroying possessions belonging to others，taking part in fights and physically attacking people.
[4]Shakira says the researchers identified the link after they considered the factors like the child’s age and sex．They also considered     ，such as whether the boys and girls were eating sweets or given fruit drinks on a normal day．In addition，the researchers examined parenting styles and other social conditions that might be taking place in the home.
[5]It is not quite clear why young children who drink a lot of soda have behavior pmblems．However，a substance oftell found in soft drinks is caffeine，which helps to make people feel energetic．Doctor Suglia suggests that caffeine could be causing the children to be more aggressive.
[6]The research is part of a larger study called the Fragile Families and Child Welibeing Study．It follows 5，000 poor mothers and their children in 20 American cities.

解析

试题分析:一项新的调查表明每天喝四杯以上软饮料的儿童比不喝软饮料的儿童更具有攻击性，有着更强的好斗性格。研究人员发现造成这种状况的原因是由于软饮料中含有的咖啡因会让人精力旺盛，从而让儿童产生了好斗的行为。
小题1:信息归纳题。本文开头提出A new study has found evidence of aggressive behavior in children who drink four or more servings of soft drinks every day，然后在下文详细叙述了调查情况，由此判断文章中心是介绍软饮料可能会造成孩子好斗的行为，答案为Soft drinks could cause aggressive behavior in children。
小题2:信息判断题。根据上文They were asked to keep a record of how many servings of soft drinks their children drank over a two-month period ….可知参与调查的母亲要记录孩子在两个月期间喝多少饮料，所以要求记录的也是孩子的行为，而且本文中心内容是关于孩子攻击性行为和饮料的关系，由此可知they指代“孩子们”，答案为The children ; Their children ; The mothers’ children。
小题3:信息查找题。根据文章第三段The aggressive behaviors included destroying possessions belonging to others，taking part in fights and physically attacking people. 可知攻击性行为包括
①destroying others’ possessions ②taking part in fights ③attacking people physically。
小题4:信息归纳题。在第四段首句Shakira….the link after they considered the factors like the child’s age and sex中提到他们考虑到年龄、性别这样的因素，再根据下文They also considered…判断此处指其他因素的，所以填other possible influences (factors)/ other factors (influences)。
小题5:信息转换题。 根据第五段a substance oftell found in soft drinks is caffeine，which helps to make people feel energetic．Doctor Suglia suggests that caffeine could be causing the children to be more aggressive.可知咖啡因会使人精力充沛，也可能使孩子更具有攻击性，而咖啡因正是咖啡中所含有的成分，由此判断喝咖啡会让人精力旺盛或者更具有攻击性，此空填energetic 或者/aggressive。
