What is intensifying of the four basic facial management techniques?
【正确答案】：In communication very often we need to respond to the expectations from the people around us and to exaggerate our facial behaviours to meet these expectations. We have all, perhaps, had the experience of receiving a present from a friend, classmate or colleague. On such occasions we normally show pleasure, surprise or excitement so that we would not disappoint him or her, even when we do not really like the gift. We exaggerate our facial responses to maintain positive social relations.
