Almost everyone knows the meaning of Mr., Mrs. and Miss. People use Mr. with men’s last names. And Mrs. is for married women and Miss is for single (单身的) women. But what is Ms?
For some time, people in the United States use Ms. before a woman’s name when they do not know whether the woman is married or not. Today many people like to use Ms. Some women feel that it is not important for people to know whether they are married or not.
There are some problems with Ms. Not all women like it. Some like the old ways of doing things. They find it difficult to pronounce (发音) the word. But young people like it.
What do people usually use before married women’s name?
