women speak more than men do

                I think that it depent on situation. In informal place, women did talk more than men. In a eperiment which test normal conversation between 2nd grade boys and 2nd girls, scientists fount out that the male conversation was not much. the boys just say a few sentences. However, famale group is more arctive, girls are more like to talk. they share eperience, they are more comfortable in this talk. (conversational Coherence, Tannen)     In contrast, male are more arctive in public situation, men talk more and bahave like an expert while women are more unacceptable to behave like an expert in public situation.                          (Tv debates&'Epert Status', Kotthoff)
