Hello， we are ostriches（鸵鸟）. We come from Africa（非洲）. We are the biggest birds in the world， about 3 meters tall！
Our feathers（羽毛） are black. We have a long neck* and two long legs. We have wings*， but we can’t fly. Flapping（拍打） our wings can help us go faster on the ground.* We can run very fast， about 80 kilometers an hour. So we are also the fastest birds on the ground！ Do you want to have a race* with us？

Flapping our wings can help us go faster on the ground.
拍打我们的翅膀可以帮助我们在陆地上走得更快。
Ha ha， you can’t see my head now.
We will hide* when we see an enemy（敌人）.
When we see an enemy， we will lie flat（平躺） on the ground and outstretch（伸展） our necks. This will make us look like a bush*.
We can carry people on our backs.
Look， the men are riding us happily. Is it funny？ They are having an ostrich race. How wonderful！
Our eggs are very big.
Our eggs are the biggest eggs in the world. An egg weighs（重） about 1.5 kilograms（千克）. They are very delicious. People like drawing pictures on our eggs too. Are they beautiful？
