第二題：英翻中【配分 25 分】 Children and adolescents should rest or drink water instead of energy drinks when they are tired, as long-term or excessive intake of energy drinks can have negative effects on intellectual development, the John Tung Foundation said yesterday. The foundation published a survey conducted last month on energy drink consumption by those aged 13 to 22 that showed that about 60 percent of respondents have tried energy drinks, but 65 percent of them did not check their ingredients. Common reasons for consuming energy drinks included for refreshment, to ease fatigue, for the taste, to replenish energy during or after exercise and to improve sports performance, the survey showed. Excessive intake of added sugar can lead to increased risks of tooth decay, obesity, a weakened immune system, irritability, changes in activity levels, increased blood pressure, cardiovascular disease and other diseases.
