Нужен перевод, только не через переводчик!

 

1. Where does Olga come from?
2. Why are there tears in her eyes when she sees the Statue of Liberty?
3. How did she get to America?
4. What did Misha and his friends think about the Statue of Liberty?
5. Why does Olga want to go to the Rockefeller Center again?
6. Who was Rockefeller?

 

Emily: Hey, Misha, Rob, Mark! Look who's coming! It's
my grandma, Olga. She's the most interesting
person I have ever met.
Olga: Hello, Emily. Hello, boys. It's nice to meet you.
Misha:You have a Russian name. That's interesting.
Olga: I am Russian. My parents came to America many
many years ago and brought me with them. I was
only a little girl, but I remember the first thing I saw
in America from on board the ship.
Rob: It was the Statue of Liberty, wasn't it?
Olga:Yes, it was. Every time I see it I get tears in my
eyes. But you've seen it yourselves, haven't you?
What do you think?
Misha: Well, to be honest... it looks great, but...
Mark: Yes, it's one of those big American symbols which
nobody believes in any more.
Rob: Everything we saw in New York is about money: all
of those skyscrapers, built by rich people and big
corporations. And there are still so many poor
people in the streets... Is that liberty?
Olga: Well, there must be some place you haven't been
to yet in the city. I could go with you and show you
something that you haven't seen.
Rob: What's that?
Olga: How about the Rockefeller Center?
Misha: But we've already been there.
Olga: Let's see it again!

Olga and the friends arrive at the Rockefeller Center.

Olga: Look at this building again, children. What do you see?
Misha: I see a very big building which was built by somebody who had so much money that he didn't know how to spend it all.
