Many people like elephants. The African elephant is the world's largest land animal, growing up to eleven feet tall. It is the elephant's trunk that makes this animal so interesting.
An elephant's strong trunk can do many things. Its trunk can be up to five feet long. Elephants can use their trunks to pick up small pieces of fruit. With their trunks, they can reach high up into trees to get the best leaves. In this way, the elephant can eat the leaves easily.
Elephants drink a lot of water each day. Elephants can use their trunks like straws(吸管). First, the elephant will suck(吸) water into its trunk. Then, it puts the end of its trunk into its mouth to give itself a nice drink.
Sometimes, elephants will use their trunks to take a shower. They can fill their trunk up with water and shower themselves. They also reach out to say hello to one another with their trunks. A baby elephant will sometimes use its trunk to hold to its mother's tail so it doesn't get lost when they walk to find a new feeding area. Elephants use their trunks to smell and to breathe(呼吸). As it swims, an elephant can hold its trunk above the water to breathe.
