问题     There are plenty of so-called energy drinks on the market. Most of them have an attractive color and cool name. But after a careful check you may find that most energy drinks contain high levels of caffeine. These drinks are typically aimed at young people, students, busy people and sports players.
    Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much.
    Caffeine raises your heartbeat. Because of this, the International Olympic Committee has limited their use. The amount of caffeine in most energy drinks is at least as high as in a strong cup of coffee or strong tea.
    Research by Australian scientists has found that many teenagers are affected by caffeine. The results of their survey show that 27 per cent of boys aged 8~12 take in more caffeine than their parents.
    There are potential health risks linked to energy drinks. Just one can of energy drink can make you nervous, have difficulty sleeping and can even cause heart attacks. Teenagers should be discouraged from consuming drinks with a lot of caffeine in them, an expert from the Australia Nutrition Foundation said.
选项
答案 市场上所谓的功能饮料琳琅满目，它们大多色彩醒目，名字极酷。不过，再仔细地看看说明，你就会发现大多数功能饮料咖啡因含量都很高。这些功能饮料都将目标人群锁定在年轻人、学生、工作忙碌的人以及运动员等。 有时，生产商宣称其饮品可以使人在从事体育运动时精力更为充沛，并能让人保持清醒的头脑。但务必小心，千万不要过量饮用。 咖啡因会让人心跳加快，为此，国际奥委会已经限制其使用。而大部分功能饮料里咖啡因的含量几乎相当于一杯浓咖啡或浓茶。 澳大利亚科学家的研究表明，咖啡因对许多孩子造成了影响，研究结果显示，27％的8岁至12岁的男孩摄入的咖啡因多于其父母。 功能饮料可能会危害健康。比如，喝一罐功能饮料就能让人产生紧张情绪，导致失眠甚至引发心脏病。澳大利亚营养基金会的一位专家指出，青少年不宜饮用咖啡因含量过高的饮料。
