Team spirit ,in my opinion,it should include three words:unity,loyalty and contribution. To begining with,every member of the team should be aware of the importance of their own role in the team,and regard the whole team as their family.Only when the team members believe that everyone of them is a part of the big family and no one missing ,can they understand the meaning of Unity is strength.And then,loyalty is vital to a successful team,too.If there is someone selfish and wants to be a hero,chances are high that he would make trouble to the team.Last but not the least,as long as you are a team member,don't hesitate to contribute to the whole team.It is no doult that the team will be wonderful if all players try their best to contribute themselves without complains. Opinions vary from person to person.What about you ?
