Who talks more，women or men？ The seemingly conflicting evidence is resolved by the difference between what I call public and private speaking.More men feel comfortable doing "public speaking," while more women feel comfortable doing "private" speaking.Another way of capturing these differences is by using the terms report-talk and rapport-talk.For most women, the language of conversation is primarily a language of rapport: a way of establishing connections and negotiating relationships. Emphasis is placed on displaying similarities and matching experiences. From childhood, girls criticize their friends who try to stand out or appear better than others. People feel their closest connections at home, or in places where they feel at home -- with one or a few people they feel close to and comfortable with -- in other words, during private speaking. But even the most public situations can be approached like private speaking.
For most women，talk is primarily a means to preserve independence and negotiate and maintain status in a hierarchical(等级制度的) social order.This is done by exhibiting knowledge and skill，and by ho1ding center stage through verbal performance such as torytelling，joking，or conveying information.From childhood，men learn to use talking as a way to get and keep attention.Therefore，they are more comfortable speaking in 1arger groups made up of people they know 1ess well，in the broadest sense，"public speaking”.
