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。
