    When the Americans were getting ready to send (送) their first men to the moon, an old Australian was

watching TV in a restaurant (饭店). There was an Englishman in the restaurant, too, and he said to the

Australian, "The Americans are clever, aren't they? They are going to send some men to the moon. It is a

very long way from our world (世界)."

     "Oh, that's nothing," the Australian answered quickly."Our country is going to send some people to the

sun in a few months. That's much farther away than the moon, you know."

     "Oh, yes, it is," the Englishman said,"but the sun is too hot for people to go to." The Australian laughed

and said,"We won't go to the sun in the day, of course. We'll go there at night."
