Mr and Mrs Smith have just opened a small restaurant. In order to1 customers, they put a notice in front of the restaurant, which said，"Meals on the 2 for Three Days. "

A foreign student happened to 3 by the restaurant on the second day. And he didn't know much English. It was lunchtime and he felt hungry. "Well，here is a restaurant. I'm going to have something to eat. "

He saw the notice when he was walking to the restaurant. "American people are really4 They even eat food on the house! But how can I get onto the 5 of the house?" He said to himself. 

He looked around and found a ladder (梯子)6 the tree nearby. He was very glad. But as he reached the top of the house, he heard someone shouting at him. "Hey, what are you doing up there?" Mr Smith was looking at him 7 . And a policeman was beside Mr Smith. "Doesn't your notice 8 "Meals on the House for Three Days"? Is it just a joke?" the foreign student answered.

After hearing this, both Mr Smith and the policeman9 . 

"Don't you know what 'ON THE HOUSE' means? Look it up in the dictionary." the policeman suggested. 

Actually，that means the restaurant provide drinks or meals for10 and you don't have to give money.
