上周，老师给了我们一个任务，要求我们以小组为单位完成作业。

Last week, the teacher gave us a task. We needed to do homework in group. At first, I was so afraid of doing the group work, because I got used to do homework alone. But later I found that I could collect more ideas and created something new. I liked to do group work and I learned so much.
