当要引起别人注意时可以说"Excuse me,Sir"或者"Pardon me,Madam/Ma'am."；在同别人打招呼时可以说"Hello Sir"或者"Good morning,Madam/Ma'am."Here are the formal titles English speakers use:英语国家人常用的正式称呼：1.Sir (adult male of any age) Sir（任何年纪的成年男性）2.Ma'am (adult female - North American) Ma'am（成年女性——常用于北美）3.Madam (adult female) Ma'am（成年女性）4.Mr + last name (any man) Mr + 姓（任何男士）5.Mrs + last name (married woman who uses her husband's last name)Mrs + 姓（用丈夫姓的已婚女性）6.Ms + last name (married or unmarried woman; common in business) Ms + 姓（已婚、未婚女性皆可,常用于商业场合）7.Miss + last name (unmarried woman) Miss + 姓（未婚女性）8.Dr + last name (some doctors go by Dr + first name)Dr + 姓（也有一些医生是用“Dr + 名”称呼的）9.Professor + last name (in a university setting)Professor + 姓（用在大学里）补充：The phrase "Yes,Sir!" (or "Yes,Madam/Ma'am!") is sometimes used by native speakers in a sarcastic way.For example when a young child tells his father to "close his newspaper" the parent might say,"Yes,sir!" and laugh.You might also hear a mother saying,"No Madam/Ma'am" to her daughter's request for something unreasonable."Yes,Sir!"和"Yes,Madam/Ma'am!"这两个表达有时会被英语国家的人用来表达讽刺的意味.比如一个小孩叫他父亲不要看报了,父亲也许会说"Yes,sir!",然后大笑.你也可以听到母亲对提出无理要求的女儿说"No Madam/Ma'am".
