C
We often talk about snails(蜗牛) and their slow movement. But usually snails don't move at all. They are in their shells(壳)—sleeping.
Hot sun will dry out(使变干) a snail's body. So when it is very hot, a snail draws its body into its shell. A snail will die in the heavy rain. So when it rains, a snail does the same thing too. A snail can sleep for a long time. It spends all the winter in its shell, sleeping.
In spring, the snail wakes up(醒来). Its body is only about 7 cm long out of the shell. When it is hungry, the snail looks for food. Its eyesight is not very good. But it has a very good sense of smell(嗅觉). This helps the snail to find food and the new plants.
A snail's mouth is no bigger than a full stop(句号). But it has about 25,600 teeth! The teeth are very small, and you can't see them. If you put a snail in a paper box, it will eat the box and find its way out! And if its teeth are too old, it will grow new ones.
