阅读理解。 Two men named Jack and Joe were walking along a road one hot summer morning. They were very thirsty (渴) and wanted very much to have a glass of cold beer (啤酒), but they had no money. 'I can get some beer for us without (没有) money,' said Jack,' Come with me.' They went to a pub (酒吧) about one kilometer away. It was lunch time and a lot of people were in the pub. The owner (店主) was selling drinks at one end of the long bar (柜台) while a waiter (招待员) was selling drinks at the other end. 'My friend and I can't agree,' Jack went up to the owner and said, 'I say there are two glasses in a litre (升) and he says there are four.' 'You're right,' said the owner, 'There are only two glasses in a litre.' 'Thank you.' said Jack, and went over to Joe. He was standing at the other end of the bar. He asked for two glasses of beer and told the waiter that the owner was going to pay for it. Then he called out loudly, 'You did say two glasses, didn't you?' 'Yes, that's right. Two glasses.'
