    Australia has a lot of lovely animals. You cannot find them anywhere else in the world. The most famous ones are kangaroos and koalas(树袋熊).

 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 nine meters 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).

 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 very angry with them.

 The koala is another famous Australian animal. They look like bears, and have small eyes and big noses. They eat leaves from eucalyptus, where they spend most of their time.

 Koalas have a special smell. They use it to mark their home—“This is my place, you can’t come in!”

Like kangaroos, a koala baby lives in its mother’s pouch.

 But koalas have fewer places to live in. There are about 100,000 koalas in Australia. There is a law to keep them safe.

It is said that another acre of the world’s forest will be destroyed forever. Why is this happening? There are two reasons — land and wood. In many countries the trees have been cut down because the land was needed for animals or crops. In other parts of the world the trees are cut down because their wood is wanted. This wood is used by local people for firewood or it is used for building. But many people don’t know that in most places the trees won’t be replaced. The soil in the forests is very thin, but it is protected by the trees. When the trees are cut down, the soil is washed away by the rain or blown away by the wind. Soon nothing can be grown on it. The  forest becomes a desert. Then more land will be needed, and more trees will be cut down.

When the forest is destroyed, it isn’t only the trees that are lost — the homes of millions of animals and plants are destroyed, too. All kinds of animals are in danger — fish，reptiles, birds, mammals, insects, and shellfish — as well as thousands of plants.

Who is to blame for this? The answer is simple: all of us. There are just too many people in the world. The world’s population is now six billion. Of course, it’s very easy to blame the local people. We don’t cut down trees. They do. But the products are bought by people like you and me — wood houses, beds, tables, chairs, paper… Why are the forests being destroyed? Just look around. You are probably using it right now.

    A. grow crops        B. keep animals    C. build houses   D. get land and wood

2. In most places, __________after trees are cut down.

A. new trees can grow better                  B. forests will become deserts      

C. most animals can live there                 D.people build new house there

3. According to the passage, we should  _________________ to protect the forest.

A. use fewer wood products            B. plant more trees      

C. blame the local people              D. protect the soil
