Elephants are very special animals. They are very smart and have different emotions(情感), such as happiness and sadness. They can even cry. Elephants can learn many things, and in some countries, people let them carry heavy things.
There are two kinds of elephants: African and Asian elephants. African elephants are usually larger and they can be 7,000 kilos or more. All elephants like eating different kinds of plants, such as grass, leaves and vegetables. They eat a lot-up to(多达)300 kilos a day. They can live for about 60 years.
Unluckily, the number of wild elephants is going down. Many people kill(杀死) them mainly for their tusks-the long pointed(尖的) teeth. Now more and more people try to protect them.
