In many corners of the world, mass malnutrition is a deadly threat to people’s life. It is plainly defined as a state of insufficiency of food for the population, where the majority of the people do not obtain enough food calories (卡路里) to meet the lowest needs for support of physical work and for maintenance of health. Compared with wars or natural disasters like earthquake or flood, mass malnutrition is rather an unnoticeable health killer, which escapes enough public attention.
In Latin America, as in other places, the frightening protein-shortage disease kwashiorkor has been said to take toll of thousands of children, greatly affecting the area’s child population and leaves many more children in terribly poor health. The reason for the problem might lie in the traditional diets in the area which are not balanced in nutrition. Here people keep their eating pattern year after year without the knowledge of what these eating habits are doing to themselves and to future generations.
In these poor areas, in stead of thoroughly altering the local people’s long-term habits, the best way might be to find food substitutes which could meet nutritional needs. Mixtures of vegetable proteins, like soybeans and peanuts could provide cheap and useful protein where meat, eggs and milk are not within economic reach of large groups in population.
Efforts could also be made to increase the agricultural productivity in some areas, where mass production of vegetable protein crops could bring life-saving nutrition to local people. Being used wrongly, large areas of land now are devoted to luxurious entertainment constructions, such as golf course or riding field, which are targeted at a small number of rich people. But isn’t a large area of productive planting land more acceptable and down-to-earth a choice to these countries suffering from mass malnutrition right now?

新思维假期作业寒假吉林大学出版社系列答案Researchers found that compared with teens who spent much of their free time in front of TV sets, those who were physically active often had higher self-respect, better grades and were less likely to have risky behavior like taking drugs, smoking, or drinking．The findings, based on a national survey of nearly 12,000 middle and high school students, were published in a journal．
"Across the board, children who engaged in any kind of activity were belier off than kids who watched a lot of TV," said study co author professor Penny Gordon Larsen of the University of North Carolina．
Other studies have linked certain content of television programs, such as violence and sex, to children's behavior．But beyond this issue, Gordon-Larsen said that kids who spend hours watching TV "miss opportunities" to develop skills, learn teamwork and have other experiences that their more active peers benefit from．
That doesn't mean, however, that kids have to be on the football team． The study found that some activities like skating and skateboarding——which adults sometimes frown upon——were also related to better self respect and less risk taking．
That skaters were better behaved than TV watchers might come as a surprise to some adults who consider these teens to be bad, according to Gordon-Larsen．Skateboarding is forbidden in many public areas, and some communities oppose building skating parks．But if kids who like to skate have nowhere to do it, "it's a shame," said Gordon-Larsen．
Not only should parents encourage their kids to engage iii the physical activities they enjoy, she said, but schools and communities should also do more to create opportunities for children to be active．
