Today, the biology class is very different. We don’t need to sit in the classroom, because the teacher takes us to do activities. We go to a field that is near our school, and the task for us is to observe flowers. We feel so excited and finish the task very carefully. It is a good way for us to learn knowledge. I am so happy. 
今天，生物课与平时不太一样，我们不需要在教室里面坐着，因为老师带我们去做活动。我们来到学校附近的一片田野上，我们的任务是观察花朵。我们非常激动，也非常认真地完成这项任务。这是一个学习知识的好方法。我很开心。
