      Bill and his friends are going hiking this weekend. He's afraid he's going to be hungry. So he buys a lot

of food and his bag is big and heavy. They start at nine in the morning and they get to the city five hours later.

They're all tired and his friends get on a bus, but Bill can't. His bag sticks (卡住) in the door and he has to

get off. The bus leaves and he doesn't know where he's going to meet them. He walks in the street and when

it's eight in the evening, he goes into a restaurant. He asks for some drinks and soon begins to sleep. When he

wakes up (醒来) in the midnight (半夜), he can't find any people in the restaurant. The door is closed and he

can't go out. He finds a telephone number on a piece of paper and begins to call Mr. Jackson, the owner of

the restaurant. "Hello," says the boy. "When do you open your restaurant, Mr Jackson?" The telephone wakes

the man up and he isn't happy. So he says,  "Don't ask me about that, I won't let you in."
