On a hot summer day, a soft drink can really take away your thirst. At home, at school, in the park or at the movies---you can find one almost anywhere.

Carbonated

You can see bubbles(泡沫) in these! Of all soft drinks sold, about 75 percent are carbonated(碳酸的). But be careful, carbonated soft drinks have lots of sugar and caffeine(咖啡因). Caffeine is not very good for you in the summer because it takes water out of your body. And the sugar can make you overweight if you drink too much.

Fruit juice

There are different kinds of juice. One kind is made only from fresh fruit. This kind of fruit juice may not taste sweet enough for some people, but it is nutritious(有营养的). Another kind of fruit juice tastes good but has lots of sugar in it. Many young people buy this kind because the advertisements are good. It is bad for your teeth and bones to drink lots of this.

Energy drinks

These kinds of drinks have caffeine and things that make people get excited in them. They are sometimes called “party drinks”. Doctors say that if you drink too much of this kind, you may have a heart attack.

Bottled water

We have lots of different kinds of bottled water, such as mineral water, purified water and distilled water(蒸馏水). They are clean and easy to drink. But it is best not to drink very cold water. It may make your stomach feel bad.

Sports drinks

Most of these have funny names like “Scream(尖叫)” and “G-Vital(激活)”. They have lots of vitamins and minerals in them. After you play sports, you may want to drink one of these.

But if you just spend your summer holiday sitting around watching TV, you won’t need them at all!
