Body language is the quiet,secret and most powerful language of all!It speaks louder than words.According to specialists,our bodies send out more messages than we realize.In fact,non-verbal（非言语）communication takes up about50% of what we really mean.And body language is particularly important when we attempt to communicate across cultures.Indeed,what is called body language is so much a part of us that it’s actually often unnoticed.And misunderstandings occur as a result of it.For example,different societies treat the distance between people differently.Northern Europeans usually do not like having bodily contact（接触）even with friends,and certainly not with strangers.People from Latin American countries,on the other hand touch each other quite a lot.Therefore,it’s possible that in conversation.it may look like a Latino is following a Norwegian all over the room.The Latino,trying to express friendship,will keep moving closer.The Norwegian,very probably seeing this as pushiness,will keep backing away which the Latino will in return regard as coldness.【Clearly,a great deal is going on when people talk.】
