The dean of Engineering had once walked into a class, and said “Good Morning”.
    一天，工程系的主任走進(jìn)一間教室說：“早上好?！?BR>    The whole class chorused “Good Morning”.
    全班同學(xué)異口同聲地回答：“早上好?！?BR>    “Hi, you are freshmen, aren’t you?” he asked.
    “你們是大一新生吧？”主任問道。
    One student bolder than the others asked him how he knew.
    班級里一個(gè)膽子比較大的同學(xué)問主任是如何知道的。
    “Well,” he said. “When I say ‘Good Morning’ to a class, if they are freshmen they say‘Good Morning’ too. If they are sophomores, they quietly fold their papers away, and look at me. A class of juniors will look at me over the top of their papers, and then get back to them. A class of seniors xiaogushi8.com will ignore my greeting, and keep reading the papers. When xiaogushi8.com I say ‘Good Morning’ to a class of graduate students, they write it down.”
    “嗯，”主任說，“當(dāng)我說‘早上好’的時(shí)候，假如是大一的新生，他們也一定會說‘早上好’的。假如他們是大二的學(xué)生，他們會輕輕地合上課本，然后集體看著我。大三的學(xué)生則會抱著書本，抬起頭看我一眼，然后又繼續(xù)讀書。大四的學(xué)生則根本無視我的存在，一直看著書。至于研究生班的學(xué)生，我向他們‘問早上’好，他們就會把這句話寫在筆記本上?！?
