Mark Twain , thefamous American writer , was traveling in France . Once he was going by train to Dijon . That afternoon he was very tired and wanted to sleep , so he asked theconductor(检票员)to wake him up when they came to Dijon . But first he explained that he was a very heavy sleeper . “ I’ll probably protest (表示不满)loudly when you try to wake me up,” he said to the conductor , “ but do not take any notice(别在意) , just put me off the trainanyway (无论如何).” Then Mark Twain went to sleep . Later ,when he woke up , it was night time and the train was in Paris already . He realized at once that the conductor had forgotten to wake him up at Dijon . He was very angry . He ran up to the conductor and began to shout at him . “ I’ve never been so angry in all my life ,” Mark Twainsaid . The conductor looked at him calmly (冷静地). “You are not half (一点也不) so angry as the American whom I put off at Dijon ,” he said .
