阅读理解。 When we don't understand each other's language, we talk with the help of signs. A Frenchman was once traveling in England. He could not speak English at all. One day he went into a restaurant and sat down at a table. When the waitress came, he opened his mouth, put his fingers into it and took them out again. The waitress soon brought him a cup of tea. The man moved his head from side to side. The waitress understood him and took away the tea. In a moment, she brought a cup of coffeeand put it on the table. The man again moved his head from side to side. He moved his head from side to side whenever the waitress brought him something to drink. She brought him a lot of different drinks, but drinks are not food of course. When the man was going away, another man came in. This man saw the waitress, and put his hand on the stomach. That was enough. In a few minutes there was a large plate of meat and vegetables on the table in front of him. So you see, we can't understand the language of signs so well as the language of words. 1. The Frenchman opened his mouth, put his fingers into it and took them out again.
