    Some people like to work alone while others enjoy teamwork. In my opinion, everyone had better learn to work with others together because teamwork is definitely necessary and important in modern society.

    First, working in a team provides a chance for us to communicate with each other. Just as the saying goes, “many hands make light job.” Working in a team, teammates share their ideas with each other, which is helpful to create a better achievement. Second, working in a team is a way to broaden our horizon(眼界). Teammates in a team can learn something from each other because they are from different places, owning various experiences and hold different views towards things. Therefore, getting along with other teammates is also a process of increasing our knowledge. Third, working in a team is also a way to establish(建立) our friendship. Teammates in a team have chances to help each other, to solve the problems together, to share the happiness of being successful, which make a great contribution（贡献） to establishing friendship.

    So working in a team is one of the most effective（有效的） ways to extend（扩展） our personal relationships. To sum up, to learn to work in a team is really necessary and important and we should try to enjoy it.
