Сам текст:
Misha: How are we going to get to England?
Rob: The cheapest way is by bus. Eurolines go all over Europe.
Misha: But how can we get to England by bus? England is an island!
Rob: Oh, that's not a problem. In France the bus goes on a ferry. It is a big boat, which can carry buses, cars and people.
Misha: How much is the bus then?
Rob: A single ticket is £52 if you are 12 years old and £148 if you are older.
Misha: That's really cheap! I am twelve. How long does it take?
Rob: I don't know. We must find out.
Misha: What about the plane?
Rob: It is the fastest way. It took me only three and a half hours to get to Russia from England. But it was expensive! I paid £350 for a return ticket with British Airways.
Misha: And what about the train?
Rob: I don't think it's a good idea. It will take a long time to get to England by train and it is more expensive than the bus.cheapest way, because a ticket ... only $52
