Помогите перевести, Text 1. Would I like to live here? I really haven't thought about it. The Australians I've met are very hospitable and much friendlier than the British. After two weeks I understood why Australia is called "the lucky country". One reason is that the weather is good. The sun is always shining. Thanks to warm, sunny weather, you can spend all the time outdoors. What a good chance one can have to look sunburned, to enjoy sunbathing and water sports. Well< Australia is a great place to live.

Text 2. I think it doesn't matter much what country it might be. Now I'm dreaming of living in a home one green hillside within a 10-minute walk of a broad white sand beach or of a nearby river. I'd like to have a lot of horses, a fertile farmland and a good climate for growing a variety of fruits and vegetables. But if I happen to change my mind, I know, I can move to any place. Because it's a vast country with various climates, landscapes and possibilities where you can always find a place to your liking.

Text 3. I don't want to live anywhere else but in Russia. I was born here and I'm not going to leave it. But a lot of countries attract me as a traveler. I've read much about European countries and I finally set my eyes on Spain. Firstly, I like its climate, hot and dry. Another reason for my choice is Spanish food. A lot of exotic fruits that I have never seen in Russia grow there. But what attracts me most of all Spain? Of course, people. Unfortunately, I haven't got any Spanish friends, even pen friends, but I believe the Russians and the Spanish have much in common.

If I happen to live in Spain, I'll live in a small provincial town, far from big cities. My house will be in the mountains where nature is wild and magic. But still it is dream, and perhaps some day I'll visit Spain, but I will only visit, I'm not going to live there. East or West, home is best. I can't imagine my life in another country without Russian friends, the Russian language, Russian frost and Russian cookery:
