An Absent Minded ProfessorA notoriously absentminded professor was one day observed walking along the street with one foot continually in the gutter，the other on the pavement． A pupil meeting him said： “Good evening，professor．How are you？ “Well，” answered the professor，“I thought I was all right when I left home，but now I don't know what's the matter with me．I've been limping for the last half hour．”
有一天，人们看见一个有名的心不在焉的老师在路上走，他的一只脚一直踏在街沟里，另一只脚踩在人行道上。 一个碰见他的学生说： “晚安，老师。您怎么了？” “啊，”这位老师回答说：“我想我离开家的时候还挺好的，可是现在我不知道出了什么毛病。我已经一瘸一拐走了半个小时了。”
