Can you check my pronunciation, please? I read the text below. More than once I saw a little blue bus going through the street of Moscow. On its sides are painted the moon and the sun, the planets and many stars. This week I discovered just what this blue bus does! And the first thing I found out was that it isn’t a bus at all, but an observatory. Moscow, as you know, has a fine planetarium. The bus is run by the planetarium's scientific workers who take it round to factories and building sites where they give interesting little lunch-time talks about astronomy, space travel, the universe.
