A trip to the USA
Teacher- Hi,everybody! I"ve got great news for you. At the end of April your group-- the winners of "English Learners Contest"-- is going to the USA!
Tanya- It's fantastic!
Misha- Wow!
Volodya- I can't believe it! It's too good to be true
Irina- I knew it! I knwe it!
Teasher- Please be quiet. I'm here to tell you all you want to know, but if you make so much noise I won't be able to do it
Volodya- When are we leaving? What places are we going to visit?
Teacher- We are starting on the 23rd of April and we are flying from Sheremetyevo to New York, Kennedy Airport.
Tanya- How long are we going to stay in New York?
Teasher- Only two days, but it's long enough to see the main sights: the Statue of Liberty, Manhattan, the famous skyscrapers, the Metropolitan and the Bronx Zoo
Irina- But New York is in the east and I have always wanted to see Hollywood and Disneyland. Are we going to do to California too?
Teacher- Yes, we are, but only at the end of our trip. Between New York and California we'll go to Philadelphia, the birthplace of America democracy, and Washington, D.C.
Misha- Just Philadelphia and Washington? Aren't we going to Texas? I've always wanred to meet cowboys or even take part in a rodeo.
Tanya- What's a rodeo, Misha?
Micha- Don't you know? It's when cowboys ride wild horses or catch wild horses throwing a lasso. I saw it in a film
Vilidya- I'd like to see the Niagara Falls. Could we please go there?
Teacher- Sorry, boys, not this time. We've got only ten days and four wonderful places to see. I'm sure you'll love them. But if you win another contest(and we're having it in May) who knows ... we may have a chance...-
