Nowadays, we are living in a competitive society. Everyone spares no effort to come to the top. I suggest when we are on the road to success, don 't lack for the cooperation.

Cooperation can facilitate us to establish a close connection with others. Take myself for instance, last week, my teacher of spoken language asked us to prepare for a short film in the form of a group to the class. To be honest, listening to this task, I felt confused and didn't know how to do it. Luckily, my group got together to think about various contents and we quickly decided the theme. After examined by our teacher, we began to perform as the playbook. Then, we teamed up to editing and rearrangement and added the subtle. Finally, we thanked our teacher and classmates for their watching. So, I think it is important for us to cooperate with others. No only us but also countries can need to cooperate. Cooperation can meet the increasing demand of economic development. When faced new challenges, countries should enhance exchanges and cooperation and mutual coordination. Only by cooperation, every country can build stable international relationship and create a favorable environment for economic development.

In a word, cooperation can facilitate the development of collectivity, society and even the world.
