     Australia has lots of lovely animals. You can't find them anywhere else in the world. The most famous

ones are kangaroos and koalas. The kangaroo is the symbol of Australia. They have large eyes and ears.

They don't walk, they jump. They use their strong back legs. They can jump at 74 kilometers per hour.

They can go over nine meters in one jump.

     Kangaroo mothers have pouches to carry their babies. The babies stay inside to get milk and keep warm.

Kangaroos are everywhere in Australia. They are on TV, in books and in the shops. But do you know that

millions of kangaroos are killed every year? There are too many of them. There are about 20 to 25 million

kangaroos in Australia. That's more than the number of people in the country. Some kangaroos go hungry

because there is not enough food to eat. They break into farms for food. Farmers are angry with them.

     The koalas is another famous Australian animal. They look like bears, have small eyes and big noses.

They eat leaves from gum trees. Koalas have a special smell. They use it to mark their home-"This is my

place, you can't come in." Like kangaroos a koalas baby lives in its mother's pouch,too.
