Teeth are important. Strong, healthy teeth help you chew foods that help you grow. They help you speak clearly. And, they help you look your best. Here are some advice for you to take care of your teeth.
● Brush your teeth the right way.
Brush your teeth at least twice a day after breakfast and before bedtime. If you can, brush after lunch or after sweet snacks（快餐）, too.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
Brush all your teeth, not just the front ones. Spend time brushing teeth along the sides and back of your mouth. Brush away from your gums（齿龈）, too.
Spend at least three minutes each time you brush. Play a song you like to help pass the time.
Get a new toothbrush every three months. When you buy your tooth brush, be sure it has soft bristles（鬃毛）.
● Learn how to floss your teeth.
Flossing is a very important way to keep your teeth healthy. Food may hide in places where a toothbrush cannot get to, like the space between the teeth. Flossing can help get rid of it. Carefully move the floss between two teeth, up and down. You need to floss your teeth at least once a day.
● Have good eating habits.
You need to be careful about what you eat and drink. Eating sugar is a major cause of tooth decay（腐朽）. Eating sugar before you go to bed can make things even worse. Eat lots of fruit and vegetables and drink water instead of soda.

We’ve talked about snails (蜗牛) and their slow move. But much of the time snails don’t move at all. They are in their shells (壳) —sleeping.
Hot sun will dry out a snail’s body. So at the least sign of hot sun, a snail draws its body into his shell. A snail will die in a heavy rain. So when it rains, a snail does the same thing, too. A snail can sleep for as long as it needs to. It spends all the winter months in its shell, asleep.
In the spring the snail wakes up. Its body, about three inches long, comes out from the shell. When hungry, the snail looks for food. Its eyes, at the end of the top feelers (触角), are very weak. But its sense (感觉) of smell is very strong. It helps the snail to find food and the new greens.
A snail’s mouth is no bigger than the point of a pin (大头针). Yet it has 256,000 teeth! The teeth are very small, and you can’t see them. If you put a snail in a hard paper box, it will eat its way out! And if a snail wears out its teeth, it will grow new ones.
