请根据以下提示，结合你校园生活中的一个事例，就与人合作这一话题，用英语写一篇短文。Working in groups at school is an opportunity to learn about team work. Teamwork shows us how other people’s roles fit the purpose of the group, and it teaches to be patient and how to respond to different people.
Years of school life has taught me a lot of things, of which teamwork is the most important for me. In fact, I didn’t realize its importance until I was chosen monitor of my class in my senior middle school. At first, I did most of the duties myself while other students cared little about class activities. As a result, I was tired out and depressed. Then I turned to my teacher and he advised me to cooperate with others. Thus I began to recognize the strengths（优点；长处） of my classmates and have everyone do their part in class. It is working in teams instead of on my own that freed me of trouble and made my work more efficient.
