1. Forty-thousand of the world’s young children die every day. This is 15-million a year. Many of these deaths can be prevented. In fact, experts say techniques now exist to save the lives of half of these children. The techniques are medically effective, simple to use and low cost. The biggest task has been to inform parents about these life-saving techniques. 2. The Untied Nations Children’s Fund, UNICEF, list four ways to improve children’s health. The first way is to use a mixture of sugar, salt and water to treat diarrhea (腹泻). The second way is to use vaccines(疫苗)to protect children against common diseases. The third way is to feed babies mother’s milk. And the fourth way is to measure carefully children’s growth rates. 3. Diarrhea is the major cause of death among children in developing countries. Diarrhea results when the body tries to clear itself of harmful bacteria. The body does this by forcing fluids out, sometimes uncontrollably, from the bowels(肠). If too much water, sugar and salt are lost in this way, the kidneys(肾)and heart cannot work normally, The child may die. 4. UNICEF’s diarrhea treatment is called Oral Rehydration Therapy. It uses a simple mixture of sugar and salt in water. The mixture does not stop diarrhea. But if used as often as needed, it keeps fluid levels normal until the body has fought off the harmful bacteria.
