Dear Sir, I (am writing) to you to see whether your school (will be interested) in taking part in exchange visits with our school. Quite recently we (have done) research ... , in case you (haven't heard) the name before! I expect you might have seen some of the cars which (are made) here. ... And last year a new sport center (was built). ... We (have already found) many families here who would be happy to receive students from your school and many of us (are looking) forward to visiting your city.
Ilya Muromets fights for his homeland. He isn't a guarder who is hired, he is a Motherland defender, although he does all his job by himself. He is strong, courageous, manly. He never lets someone in trouble. He is clever, kind and friendly. Ilya Muromets is ready to give his life for the righteous cause. He is Russian; he is fair-haired and blue-eyed. He is a soldier and he was dedicated by elders. He makes ordinary people's dream come true and their dream is to live in peace. So Ilya Muromets puts all his efforts into clearing his homeland from villains, enemies and bad people who want to occupy his Motherland and break the peace amongst ordinary people.
