Australia has a lot of lovely animals. You cannot find them in other places in the world. They are only from Australia-kangaroos (袋鼠) and koalas.

The kangaroo is the symbol animal in Australia. They have big eyes and ears. They don’t walk, they jump. Kangaroo babies live in their mother’s pouches when they are very young. The babies stay in it to get milk and sleep in it.

We can see kangaroos here and there in Australia. They are on TV, in books and in the shops. But do you know how many kangaroos there are in Australia? There are about 20,000,000 to 25,000,000 kangaroos in Australia. Some kangaroos go hungry because there is no food to eat. They often get into farmers’ houses to look for their food.

The koala is another animal from Australia. They look like bears, and have small eyes and big noses. They sleep during the day, but they get up and eat leaves from trees at night. Every koala has its own (自己的) place. It often says to the others, “This is my place, you can’t come in!”
