Jack is an Englishman. He likes travelling around the world. He has visited many countries. He knows few foreign languages, but he can always find someone who knows enough English to understand what he says. Last summer he went to China. He enjoyed himself in China and liked Chinese food very much.

One day he went into a restaurant in a small village. He knew the Chinese word ‘rice’, so he ordered some rice. The village was famous for its mushrooms, and Jack thought they must be very fresh and delicious. He asked the waiter in English, but he could do nothing for Jack. Jack thought hard. When he saw a piece of paper on the table, he had a good idea. He took out a pencil and drew a picture of a mushroom carefully.
