At first，Jack wasn’t fond of studying and was addicted to computer games.Every time his mother went① to his room，she found that he was playing② computer games.His father had condemned③ him many times before he went to middle school，so he promised that he would study④ hard and quit computer games.
It is amazing that Jack has changed⑤ a lot in the past three years.Whenever asked about Jack’s performance at school，his mother always answers⑥ proudly，“He has been making⑦ progress.”He is making⑧ preparations for the college entrance exam.
There is no doubt that Jack will be admitted to⑨ a good college if he keeps working hard like this.Maybe in the near future he will be studying⑩ in a key university.
