问题     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.
    Diarrhea(腹泻) is the main cause of death among children in developing countries. Diarrhea results when the body tries to clear itself of harmful bacteria(细菌). The body does this by getting out liquids, sometimes uncontrollably. If too much water, sugar and salt are lost in this way, the body cannot work normally. The child may die.
    The United Nations International Children’ s Fund, UNICEF, introduces a technique. It uses a simple mixture of sugar and salt in water. The mixture does not stop diarrhea. But if used often as needed, it keeps fluid (体液) levels normal until the body has fought off the harmful bacteria.
    In Egypt, for example, the treatment was used in a children’ s health care program in the province of Alexandria. It reduced by one-half the number of deaths caused by diarrhea. The technique has now been used throughout the country. [br] Which of the following situations will cause the death of a child?
选项 A、The child clears its body of bacteria.
B、The body loses liquids without any control.
C、The child has diarrhea in a developing country.
D、The body controls its fluid levels.
答案 B
解析 在文章的第二段最后部分“If too much water，sugar and salt are lost in this way，the body cannot work normally．The child may die．”，也就是说孩子腹泻会让孩子失掉大量的水分，盐分和糖，这样往往才是导致孩子因腹泻而死亡的真正原因。故正确的答案为B。
