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，人們看見一個有名的心不在焉的老師在路上走，他的一只腳一直踏在街溝里，另一只腳踩在人行道上。 一個碰見他的學生說： “晚安，老師。您怎么了？” “啊，”這位老師回答說：“我想我離開家的時候還挺好的，可是現在我不知道出了什么毛病。我已經一瘸一拐走了半個小時了?！?
