Keep One＇s Nose in A Book.

　　Professor John was called to the office.

　　“I＇ll be back in a few minutes，”he told the students.

　　“While I＇m gone，though，I want you to keep your noses inyour books.To make sure you do，I＇ll be giving you a testwhen I return.”When the Professor came back，he found thatthe students had not obeyed his request--more or less！“what a shame they＇ve gone，”he said to himself，“I guessthey didn＇t know that to keep one＇s nose in a book simply means to read or study abook。”

　　办公室要约翰教授去一下。

　　“我几分钟就回来，”他对学生说：“虽然我出去了，但我希望你们继续看书，一定要做，我回来后会考你们的。”当他回来时，发现学生并未照他要求的做！“他们真不像话，”他自言自语地说：“我猜他们没有一个人知道Keep one＇s nose in a book就是指埋首阅读或者学习。”(《人民日报海外版》2001-03-02)
