    Cola is bad for our health. Cola is sweet, because it has sugar in it. Too much sugar can let you get fat. Drinking one bottle of cola each day can make you get fifteen pounds(磅) each year. And because the sugar in cola can make you feel full, you can't eat much healthy food, such as fruit, vegetables and rice. And cola is bad for your teeth and bones(骨头).

Drink water, please. Water is very important to our body. It keeps us healthy. We get water from drink and food, especially(特别是) from fruit and vegetables. But it's better to drink water. If you don't like plain(清淡的) water, you can put a little 100% fruit juice into it.
