Three men got to Dover station a few minutes after nine o'clock one evening．They asked a guard, 'What time is the next train for London?'
The guard said, 'You've just missed one．A train goes every hour．The next one is at ten o'clock.'
'That's all right,' they said, 'We'll go and have a drink.' So off they went to a bar (酒吧间)．A minute or two after ten o'clock they came running and asked the guard, 'Has the train gone?'
'Yes,' the guard said．'It went at ten, as I told you．The next one is at eleven o' clock.'
'That's all right,' they said again．'We'll go and have another drink.' So they went back to the bar.
They missed the eleven o' clock train in the same way．Then the guard said, 'Now, the next train is the last one．If you miss that train, you won't get to London tonight.'
Twelve o'clock came, and the last train was just starting out when the three of them came out of the bar running as fast as they could．Two of them got in the train just as it was leaving, but the third one didn't run fast enough, and the train went out leaving him behind．He stood there looking at the train and laughing, as if (好像) to miss a train was the best joke in the world．The guard went up to him and said, 'I told you that this was the last train．Why didn't you come earlier?'
The man kept laughing until tears came into his eyes．Then he caught hold of the guard and said, 'Did you see the two men get into the train and leave me here?'
'Yes, I did.'
'Well, I was the only one to leave for London．They were here only to see me off!'
The guard told the three people that there ______.
