2012年秋，新生入学伊始，北京、上海等地多所学校开出“苹果班”教程，学生上课时使用iPad回答问题，放学后家庭作业也需要用iPad来完成。对此不少家长产生疑虑，认为加重了经济负担；孩子也可能沉迷游戏、影响学习。但也有不少家长反映，用高科技教学，不仅能提高孩子的兴趣，更能减少“拉箱书包”给孩子造成的负担。请围绕这个话题写一篇英语短文，并谈谈你的看法。

After failing in the exam，my life got such dark that I didn't want to study any more. I always hid myself in his bedroom and cried quietly. In my family，I felt I am never important. I was not allowed to watch TV，using the computer or go out unless permitted. What's more，I had to stay in the study except when having meals. I almost lost my heart.
But one evening，my friend Zhang Wen came special to see me. She told me，“Nothing is impossible. You should believe in yourself.” Encouraging by what she said，I regained confidence，and made up my mind study. I hoped that I could catch up to others.
