     The weather is getting hotter. You are thirsty 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 (咖啡因) 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 has limited (限

制) 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.
