pause is a very common phenomenon in spoken english, which is defined as a break or filler of equal to or longer than 0.2 or 0.3 second (riggenbach, 1991; zhang wenzhong, 2002). learners need pausing linguistically and physically when they speak english. it often happens when speakers don#8217;t know how to say or what to say. some researches classify pauses as filled pause, unfilled pause or silence (lennon, 1990; smith and clark, 1993; richard, 2002). pause has the function to adjust speech speed and to arouse the attention of listeners. therefore, pause is an essential part of communication.

numerous analyses on pauses have already been made by many scholars so far, among which some have talked about the influence of pause on oral fluency and disfluency. and the researches are from home and abroad.
