问题    Nutritional(营养的) status affects children’ s behavior. Well-nourished children are more alert and attentive and are better able to benefit from physical and learning experience. Poorly nourished children may be quiet and withdrawn, or too active during class activities. Fat children also face many problems. They are often slow and less able to participate in physical activities. They may suffer from being laughed at and emotional stress by being excluded from playmates.
   Children’ s resistance to infection and illness is also definitely influenced by their nutritional status. Children who are well nourished are less likely to become ill: they also recover more quickly when they are sick. Poorly nourished children are more sensitive to infections and illness. Illness also increases the need for some nutrients. Thus poor nutrition creates a cycle of illness, poorer nutritional status, and lowered resistance to illness.
   Malnutrition is a serious problem for many young children but it is not always associated with poverty or a poor environment. Children of middle and upper income families may also be malnourished because of unwise food selections. Malnutrition occurs when there is prolonged (拖延的) imbalance of the nutrients that are required and the nutrients that are actually eaten. Malnutrition may be the result of under-nutrition or over-nutrition.
   It is important that both of these conditions be avoided in young children. An adequate intake of all required nutrients is most vital during early periods of growth and development. Also, the effects of nutritional deficiency on physical development during early childhood are less likely to be changed by improved dietary intake later.
It is implied in the passage that______.

选项 A、over-nutrition is even more harmful than under-nutrition
B、malnutrition has serious effect on children’s physical development
C、the nutritional condition of young children deserves more concern than that of adult
D、the nutrients intake can be improved as the child grows up

答案C

解析 根据第四段“…both of these conditions be avoided in young children…is most vital during early periods of growth and development...during early childhood are less likely to be changed…”可推知,孩子的营养均衡比成年人更为重要,因此也更值得关注。故选C。
