阅读理解。 Australia has a lot of lovely animals. 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 up to 74 kilometers per hour. They can go over ninemeters in one jump! Kangaroo mothers have pouches (育儿袋) 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. The government even wants to put them on passports (护照). 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 t o eat. They break into farms for food. Farmers are very angry with them. To help the farmers, the Australian Government kills somekangaroos each year. The koala is another famous Australian animal. They look like bears, and have small eyes and big noses. They eat leaves from gum trees, where they spend most of their time. Koalas have a special smell. They use it to mark (标识) their home - "this is my place, you can't come in!"
