Упражнение 5. Прочитайте текст. Определите, какие из приведенных утверждений 1-7 соответствуют содержанию текста (True), а какие не соответствуют (False).
It was in the morning and Millie and Billy finished their breakfast. They helped Mummy to wash the dishes.
“Can we go out to play now?” they asked.
“I’m afraid not,” Mummy said. “The weather is awful.”
Millie and Billy looked out of the window. It was windy and it was raining.
“It’s very cold too,” Mummy said. “So you’ll stay at home.”
“What can we do then?” Billy asked.
“You can have indoor fun,” Mummy said. “Think of things that will be fun to do indoors and do them.”
So, that is what they did.
They draw some pictures and coloured them. Millie did a picture of an elephant and Billy did one of a bear.
Then they looked all around the house for secret places. They couldn’t find one but what they found was a little toy dinosaur behind a cupboard in the spare room. The toy was dusty, the children washed it and it was as good as a new .
After that they made a camp in the living room. They took the dinosaur into the camp.
Later Millie and Billy played “scary monsters”. Millie put on the monster mask. It was a Halloween mask. And Billy was ghost.
When it was bath time, Millie and Billy played again. This time they were fishes and they were swimming in the river.
“We really had lots of indoor fun today!” Billy said.

“Sweet dreams,” Billy replied sleeply and soon he and Millie were sleeping of indoor games.
