Мой лучший друг Пушок достался мне от наших соседей, когда они всей семьей насовсем уезжали из родного города. Мы росли вместе с этим замечательным псом, которого я знал с детства. Мы часто играли и гуляли с ним вдвоем. Пушок – беспородная дворняга, но его уму и сообразительности позавидует любой чемпион собачьих выставок. Он послушно выполнял все команды и, даже, мог сам придумать интересную забаву. Например, спрятаться от меня так, что найти его я не мог, пока он не выпрыгивал или не выбегал из неожиданного тайника с веселым лаем. На аглийском My best friend Down I got from our neighbors when the whole family was gone forever from his native city. We grew up together with this wonderful dog, whom I knew since childhood. We often played and walked with him alone. Fluff – mongrel a mongrel, but his intelligence and ingenuity envy of any champion dog shows. He obediently fulfilled all the commands and even he could come up with an interesting fun. For example, to hide from me, so that to find him I couldn't, until he jumped out or not out from an unexpected hiding place with a cheerful barking.
Australia, or the Commonwealth of Australia, as it is officially called, is situated on the island continent. It also occupies the Island of Tasmania and some minor islands round the coast of the continent.
It is a highly developed industrial-agrarian country. Its area is about 8 million km2. It is the only state in the world that occupies the territory of a whole continent.
The capital of Australia is Canberra, which became the capital only in 1927.
From 1787 to 1867 Australia was a place where criminals were sent from Britain. That is why the official language of Australia is English.
Almost one half of Australian territory is occupied by deserts and semideserts. For quite a long period of time it was thought to be useless for economic development. But it is rich in coal, iron ore, bauxites, uranium, lead and many other mineral resources.
For almost a century the production and export of sheep wool was the basis of the economy of the country. Now the most important industries are oil, chemical, ore mining, radioelectronics, and food industry. The country exports agricultural products and raw materials.
As for the nature, the commonest trees of Australia are the eucalyptus and the Australian acacia or mimosa, the national emblem of the country. Such unusual animals as a kangaroo or a koala-bear originate from Australia.
Australia is one of the most unusual and exotic countries of the world. A significant feature of modern Australian society is the representation of a lot of cultures drawn from many lands by its people.
Historically part of the British Empire and now a member of a Commonwealth of Nations, it is a relatively prosperous and independent nation.
