     The ostrich (鸵鸟) is the largest bird in the world. From far away, it looks more like a camel than a

bird. It has a long neck, long legs and a walk like a camel. Its eyes are very large and sharp. Like the

camel, the ostrich can go for a long time without water. It lives in sandy desert, too.

     Its wings are too short for flying, but they do help the ostrich to run fast. The wind gets under the

wings and lifts the bird off the ground. In this way, it can take very long steps. An ostrich can run faster

than a horse.

     Ostriches are big and strong, but sometimes they do not seem very smart. When they are afraid, they

run around in circles.

     Ostrich eggs are large. The shells are very strong. They are so strong that they can be used for cups

and bowls.
