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-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 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 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.
