Em thấy hành vi của Hùng, Phong và Thái là không đúng . Các bạn học là để hiểu biết nhưng nếu như các bạn lại đi chép bài nhau vì mục đích của các bạn đi học để được điểm cao chứ ko phải đi học để hiểu biết. Từ đó suy ra: ba bạn ấy phải tự làm chứ không nên làm vậy vì làm vậy là sai.

- Nếu là bạn của ba bạn trên, em có thể ứng xử như thế nào ?

Nếu em là bạn của ba bạn trên, em sẽ:

1. Khuyên các bạn ko nên làm vậy

2. Em sẽ khuyên các bạn nên mỗi người tự học và giải thích cho các bạn nên vì sao nên làm vậy.

3.Nếu các bạn ko nghe thì báo với Giáo viên .
