КОНТРОЛЬ ЧТЕНИЯ
1) Прочитать текст 2-4 раза и ознакомиться с незнакомыми словами.
FILM STAR
Pauline wanted to be a film star. When she was twelve she said to her parents, “I want to be a film star.”
But it was not easy. She got into films- not as a star- she became an “extra” – one of the people in a crowd.
No director asked her to be a star; the telephone never rang to offer her a big part.
One evening the man at the agency called her up and said “There is a film for you tomorrow, Pauline. Come by eight o’clock. You’re a telephonist.”
Pauline came to the studious by a quarter to eight. She waited three hours before they came to the scene she was in.
The assistant director showed her where to sit – there were two other girls with her.
“O. K., Ben,” said the director. “Are you ready?”
“Yes, Mr K.,“ said the assistant.
It was very short: the star, a famous American actor, came to the girls and stopped in front of where Pauline was sitting. Mr K. did not like it. “That’s bad,” he said, “very bad. Put some dialogue in there.”
The two men talked for a moment and then Mr K. said, “Hey, you at the end of the row there.” Pauline jumped.
“Me?” she asked.
“Yes, you. I want a line from you here. I want you to look at Harry when he comes in and say, “Mr Marlowe, there’s a call for you! An you say that?”
Pauline said she could, and they ran the scene throuth. This time Mr K. was very pleased, and the star smiled at her.
“That’s great,” Mr K. said, coming over to Pauline. “What’s your name?”
“Pauline Grant.”
“I like that, Pauline,” Mr K. said. “Thanks.”
Pauline was very happy that evening.
Some week later she booked two seats for the premier and went to see her film with her boy-friend Michael.
Before the film started she saw Samuel K. only a few feet away from her.
It was a good film but there was no Pauline in it. Her scene together with many other unimportant scenes had been cut out.(After Piers Plowright)

2) To offer – предлагать
3) I want a line from you. - я хочу, чтобы вы сказали несколько слов.
