写作指导

这是一篇描写文(Description)。用通俗的话说,描写文就是用文字给人物、地点、景物画象。一篇描写文主要是通过所感受的细节——所见所闻发展而来的。在写人时,不仅仅要用细节描写其外貌,而要注重通过他的言行来表现其人物性格、思想和品德,更要抓住他区别于他人的性格特点,这样就容易给读者留下深刻的印象。短文的第一、二段叙述故事发生的时间、地点,故事发生的原因及故事所涉及的人物。文章的三、四、五段描写的是人物的外貌,穿着及性格特点。通过对人物言行的简单描写来揭示主人翁的助人为乐的高尚精神。短文的最后一段,要用一句话概括作者对主人翁的看法:Agoodguy。文章有描述,有议论,要加叙加议,有血有肉,上下文连贯要紧密,首尾要呼应,人和事要给人们留下深刻印象。
