[解析]
There was a time when I was addicted to playing phone game all day and all night, caused me to fall asleep in class frequently.One day I was sleeping while my headteacher called my name and it was the fourth time that I have slept in English class.Therefore,he severe criticized me.It was not until then ∧I realized I had made such silly a mistake.While falling far behind,I decided to study hard and caught up with my classmates.With your teacher's help,I would surely make a great progress in the coming examination.
解析
1.game改为games.考查名词.根据状语 all day and all night可知作者玩了很多游戏,所以用可数名词复数games.
2.caused改为causing.考查现在分词.做I was addicted to playing phone game all day and all night,的必然的结果状语,用现在分词causing.
3.while改为when.考查连词.和was sleeping 连用,引导时间状语从句 my headteacher called my name ,表示"就在那时",用when.
4.have改为had.考查固定句式.和it was the fourth time that 连用,因为主句用了一般过去时态,所以从句的谓语动词用过去完成时态,所以 have改为had.
5.severe 改为severely.考查副词.修饰动词criticized用副词,所以severe 改为severely.
6.I前加that.考查强调句式.强调状语not until then ,用强调句式It was …that,所以I前加that.
7.such改为so.考查单词辨析.such修饰名词;so修饰形容词和副词,所以修饰形容词 silly ,such改为so.
8.caught改为catch.考查动词.做decided的宾语,和动词不定式to study hard up with my classmate并列,用省略to的动词不定式,所以caught改为catch.
9.your改为my.考查代词.根据上下文可知表示"在我老师的帮助下",所以your改为my.
10.去掉a.考查冠词.progress是不可数名词,所以去掉a.
