90：请问怎样使用Mr., Mrs., Ms. 和 Miss这些称呼？

Question 90: Can you tell me how to use the titles such as Mr., Mrs., Ms. and Miss?

Answer: People often show confusion when using the abbreviations Mr., Mrs., Ms., and Miss. The female abbreviations can get tricky for beginners.

Mr. is the obvious and the easiest. It shows that one is talking of a male subject.    e.g.
Mr. Smith is a very nice principal.

Mrs. is related to the female gender. Mrs. means that the female is married or has taken a spouse.    e.g.
Mr. and Mrs. Snow celebrated their tenth anniversary of marriage last week.

Ms. is also related to the female gender. Ms. is used when the marital status of a woman is unknown or irrelevant.    e.g.
Dear Ms. Baker, …

Miss is used as a courtesy title to an unmarried woman.    e.g.
Miss Carter is in her first year of teaching.

问题90：请问怎样使用Mr., Mrs., Ms. 和 Miss这些称呼？

回答：人们时常搞不清楚该怎样使用Mr., Mrs., Ms. 和 Miss这些缩写。对于初学英语的学生来说，对于女性的称呼的使用更是一道难题。

Mr. 最明显也最容易。他表示被谈论的那个人是名男性。 例如：
Mr. Smith is a very nice principal.

Mrs. 和女性有关。 Mrs. 意味着那名女性已经结婚，或是已有配偶。 例如：
Mr. and Mrs. Snow celebrated their tenth anniversary of marriage last week.

Ms. 也同女性有关。 当那名女性的婚姻状况不得而知或无关紧要时，就采用Ms.。例如：
Dear Ms. Baker, …

Miss 是对未婚女子的尊称。 例如：
Miss Carter is in her first year of teaching.
