Children brought up on healthy diets are more intelligent compared with their junk food ea

Children brought up on healthy diets are more intelligent compared with their junk food eating partners, a new research suggests．
Kids fed a diet packed high in fats, sugars, and processed（加工） foods had lower IQs than those fed pasta（意大利面食）, salads and fruit, it was found．
The effect is so great that researchers from the University of Bristol said those children with a healthier diet may get an IQ improvement．
Scientists stressed good diet was essential in a child's early life as the brain grows at its fastest rate during the first three years of life．
This indicated head growth at this time is linked to intellectual ability and “it is possible that good nutrition（营养） during this period may encourage excellent brain growth” ．
Scientists tracked the long term health and happiness of around 14,000 children born in 1991 and 1992 as part of the West Country's Avon Longitudinal（纵向的）Study of Parents and Children （ ALSPAC） ．
Parents were questioned about the types and frequency of the food and drink their children consumed when they were three, four, seven and eight and a half years old． According to their different changing form, these children were marked and given grades which ranged from minus two for the most healthy to10 for the most unhealthy．
In the research, IQ was measured of 4,000 children when they were eight and half years old, using a validated（经过认证的）test－the Wechsler Intelligence Scale（韦氏儿童智力量表） for Children．
The results found after taking account of some influential factors, a leading processed food diet at the age of three was associated with a lower IQ at the age of eight and a half , whether the diet was improved after that age．
Every l point increase in dietary pattern score was associated with a l.67 fall in IQ．
【小题1】Scientists stressed good diet was essential in a child’s early life because .A．the brain grows at its fastest rate during the first three years of life．B．those children with a healthier diet must get an IQ improvement．C．children brought up on healthy diets are less intelligent．D．these children were given good grades．【小题2】Which of the following is NOT true?A．Those children with a healthier diet may get an IQ improvement．B．Good nutrition at any stage may encourage excellent brain growth．C．Scientists tracked the long term health and happiness of about 14,000 children．D．Every l point increase in dietary pattern score was associated with a l．67 fall in IQ．【小题3】The results found if a child ate a leading processed food diet when he was 3, he would ．A．have a higher IQB．have a higher IQ as long as he improved his dietC．have one IQ when he was 8D．have a lower IQ whether he improved his diet【小题4】What is the best title of the passage?A．Food for thoughtB．What is healthy food?C．Healthy diet improves children's intelligenceD．How to become clever?A

(答案→)A 解析：说明本文讨论的话题是健康的饮食会带来很高的智商的话题。【小题1】A 细节题。根据文章第四段Scientists stressed good diet was essential in a child's early life as the brain grows at its fastest rate during the first three years of life．说明在最初的三年里脑部的发育最快，故A正确。【小题2】B 推理题。根据文章第五段This indicated head growth at this time is linked to intellectual ability and “it is possible that good nutrition（营养） during this period may encourage excellent brain growth”说明良好的营养在这一阶段可以导致很好的脑部的发育，并不是在任何年龄段都有很好的影响，故B项说法错误。【小题3】D 细节题。根据文章倒数第二段The results found after taking account of some influential factors, a leading processed food diet at the age of three was associated with a lower IQ at the age of eight and a half , whether the diet was improved after that age．说明如果在三岁的时候有很好的营养，那么就会有较高的智商，故D内容正确。【小题4】C 主旨大意题。根据本文的主题段第一段内容Children brought up on healthy diets are more intelligent compared with their junk food eating partners, a new research suggests．说明饮食很健康的孩子的智商可能会更高，说明本文讨论的话题是健康的饮食会带来很高的智商的话题。故C正确。
