Many of us enjoy watching animals in the wild．They usually make us pleased，cheer us up and，sometimes，even get us scared．But did you know they can teach us？Geese，for example，teach a very good lesson about teamwork．
In fall，Canada geese fly south to get away from Canada's cold winter weather．They lift off in no order．Yet very quickly they form a V shape，with one bird leading the flock （雁群）．Scientists have discovered that geese flying in a V-shaped formation can help them to save energy．In this way，they can fly 70percent farther without rest than birds flying alone．
How does this apply to （适用于） humans？
Work together．Whether it is in our personal lives or our professional ones，we need other people．We are encouraged by their enthusiasm and energy．If we face the difficulties in life alone，the risks are greater．
Be an encourager．We have found that geese make sound in flight to encourage those up front to keep up the speed．Team members should regularly communicate with each other while working towards a common goal．
Take turns．The goose out in front has the hardest job as it breaks up the air currents．When it gets tired，it moves behind，and another goose moves into the lead．By sharing the role，the flock can travel great distances．Teams can benefit from the same idea．Based on their experience and skills，people can take turns sharing the leadership role．
Set a good example．When geese are on land，if something scares the leader，it might fly off．So does the flock．But if the leader remains calm，the flock will do the same．Geese and people usually___ their leaders．When leading，we must remember that our actions and emotions are passed on to our followers．
Like geese，when we work together，our burdens are lighter．
