The weather is getting hotter. You are thirsty（口渴的） playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you are drinking. Something that looks cool may not be good for your health. There are plenty of “energy drinks” on the market. Most of them have beautiful colors and cool names. The lists on them tell you they are helpful to your health. Sounds great!
But after a careful check you may find that most energy drinks have lots of caffeine(咖啡碱)in them. These drinks are especially 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 makes your heart beat fast. Because of this, the International Olympic Committee(IOC)（国际奥委会） has limited its use. Caffeine in most energy drinks is at least as strong as that in a cup of coffee or tea. Possible health dangers have something to do with energy drinks. Just one box of energy drink can make you nervous, have difficulty sleeping and can even cause heart problems. Scientists say that teenagers should be discouraged from taking drinks with a lot of caffeine in them.

(答案→)D
解析：文章大意：这篇文章讲的是当天气变热或者运动之后，人们往往喜欢喝一些能量饮料，但是这些饮料含有大量的咖啡因，对身体是很不健康的，所以作者建议大家要少喝这些饮料。
【小题1】D主旨大意题。这篇文章主要是围绕能量饮料展开的，讲了能量饮料的成分，人们为什么爱喝能量饮料以及能量饮料对身体的危害。故D正确。
【小题2】C词义推测题。第四段Just one box of energy drink can make you nervous, have difficulty sleeping and can even cause heart problems. Scientists say that teenagers should be discouraged from taking drinks with a lot of caffeine in them.一瓶能量饮料就能使你紧张，失眠。甚至导致心脏病。由此，可推断出科学家说对青少年应该是阻止他们喝含有大量咖啡因的饮料。故discouraged的意思应是阻止，可替换成stopped。故C正确。
【小题3】A推理判断题。从文章中我们可以了解到广告对于人们购买饮料有着很重要的作用。能量饮料对于青少年的学习没有帮助。运动员应该少喝能量饮料。These drinks are especially aimed at young people, students, busy people and sports players.这些饮料的目标人群是针对年轻人、学生、忙碌的人们和运动员。可知，B,C,D错误。故A正确。
【小题4】B细节理解题。由第二段Most of them have beautiful colors and cool names. The lists on them tell you they are helpful to your health.大多数的能量饮料有着诱人的颜色和酷酷的名字。从饮料的标签可由看出这些饮料有益健康。由第三段Makers sometimes say their drinks make you better at sports and can keep you awake.制造生说他们的饮料能够使你更擅长体育而且能使你保持清醒。可知，以上就是大多数人选择能量饮料的原因。故B正确。
