video games.all of us were interested in it.we learned a lot from the discussion.video games have become very popular in recent years.wherever you go，you can always see the middle school students playing the games in internet bars or at home.when we were children，almost all of us enjoyed playing video games.we had a good time.but the majority spent too much time playing them，which certainly did harm to our health and study.video games can train us to respond to things quickly，and develop our imagination and interest in computer science.obviously games give us great pleasure and satisfaction.in my opinion，in the future，we can combine video games with programmes.we can design buildings，cars，cartoons and clothes with the help of video games.in conclusion，video games are a kind of wonderful entertainment.if we have enough selfcontrol capacity for playing them，we can certainly not only relax ourselves but also gain benefit from them.【点评】1巧妙地引入正题。此文第一句this afternoon we had a discussion about.点出本次讨论的话题是讨论playing video games。2层次清晰。第二、三、四段分别说明了在过去、现在学生玩电子游戏的状况和未来对电子游戏的设想。3用词恰当。此文中使用了较高级词汇obviously，pleasure and satisfaction，respond，imagination，computer science，majority。4句式复杂。较为复杂的句子wherever you go.和which certainly does harm to.都是得高分的依据。5过渡自然。in my opinion，in conclusion，not only.but also.都起到了画龙点
