第1讲 谓语动词
考点一 动词的时态
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 exams.
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.
