[解析]
Recently,the phenomenon of stuff exchanging has caused my attention.For me,I am looking forward to getting a watch by giving my computer out.(开头引出话题并提出将拿出什么物品进行交换)
There are two reasons for this exchange.For one thing,this computer,popular﹣brand and stable,is available at my home.Though it looks old,the soft wares and hard wares go well in it.Despite the tiring appearance,it never makes troubles eventually.For another,never have I worn a watch.【高分句型】On condition that a watch was as profitable as the computer,I would be thankful.【高分句型】Of course,however,I will not accept broken stuff.(具体介绍该物品及希望换回什么物品)
By the way,anyone who likes my computer reply to me in this way please,【高分句型】and I am happy to tell you every detail about it until you know it completely.(请愿意交换的朋友给你留言)
