Last summer, Robert and Harry stayed at their grandparents' house by the sea. One hot and sunny morning, Grandmother made a picnic and took the boys to the beach. After lunch, Grandmother laid down and opened her book. The boys were playing football on the beach and then made a little castle with some sand. Then Harry saw a strange cave which was near some big, grey stones at the other end of the beach. The boys quickly ran to it and looked in, but they couldn't see anything because it was very dark. Harry said, "It looks big inside. Come on! I'll go first." Harry and Robert were playing inside the cave when suddenly Robert said, "Oh no! I can hear the sea! It's coming into the cave." They were very afraid, but then Harry felt something wet on his hand. It was their dog's nose! The dog was very smart. It showed the boys the way out of the cave and back to the beach. When they told their grandmother about the dog, she gave it three biscuits and said, "Well done!" "We're hungry too" the boys said, "Well", Grandmother answered, "you must wait when we have a dinner. It was silly to go into a dangerous place like that." "We're very, very sorry, Grandma!" they said. "We won't do it again." a) true b) false 1) The weather was hot and rainy. 2) Harry went first into the cave. 3) It was dark in the cave. 4) The dog couldn't help the boys. 5) Grandmother gave the boys tasty things.
