All parents know it is difficult to get children to eat their vegetables. Some of them offer rewards or treats for children finishing their share. But researchers have discovered that youngsters who are not praised for trying vegetables are more likely to eat them eventually. (16) The study found that the best way to get children to eat food they do not like is simply to give them repeated exposure to it.
    Psychologists from Ghent University in Belgium, studied 98 children. They gave them 5 kinds of vegetables to eat: mushrooms, peas, eggplants, carrots and cabbages. (17) The taste tests revealed that carrots were the least liked vegetable among youngsters. The children were then given a bowl of boiled carrots and told to choose how much to eat. After 8 minutes they were asked to rate the dish as delicious, just okay or disgusting. The trial went on twice a week for a month with a follow-up taste test after 8 weeks. Children were split into three groups, with one group asked to try the bowl of carrots repeatedly with no further encouragement. The other two groups were given rewards of a toy or verbal praise. (18) After the trial, 81% of children who simply try the carrots consistently liked them. This is contrast to 68% for the group given a toy and 75% for the group given verbal praise.
Questions 16 to 18 are based on the passage you have just heard.
16. What is the best way to get children to eat vegetables according to a recent study?
17. What did the researchers find about carrots?
18. What does the result of this research show?

选项 A、Vegetables differ in their nutritional value.
B、Children’ s eating habits can be changed.
C、Parents watch closely what children eat.
D、Children’ s choices of food vary greatly.

答案B

解析 题干问的是研究的结果表明了什么。短文中提到,实验结束后,持续尝试吃胡萝卜的孩子中81%的孩子喜欢上吃胡萝卜,被奖励玩具的人中有68%的人喜欢,给予口头奖励的有75%的人喜欢。由此可知,孩子的饮食习惯是可以改变的,故答案为B(孩子们的饮食习惯可以改变)。A项(各种蔬菜的营养价值是不同的)、C项(父母密切关注孩子们吃什么)和D项(孩子们对食物的选择差异很大)短文中均未提及,故排除。
