寫作指導
這是一篇描寫文(Description)。用通俗的話說，描寫文就是用文字給人物、地點、景物畫象。一篇描寫文主要是通過所感受的細節——所見所聞發展而來的。在寫人時，不僅僅要用細節描寫其外貌，而要注重通過他的言行來表現其人物性格、思想和品德，更要抓住他區別于他人的性格特點，這樣就容易給讀者留下深刻的印象。短文的第一、二段敘述故事發生的時間、地點，故事發生的原因及故事所涉及的人物。文章的三、四、五段描寫的是人物的外貌，穿著及性格特點。通過對人物言行的簡單描寫來揭示主人翁的助人為樂的高尚精神。短文的最后一段，要用一句話概括作者對主人翁的看法：Agoodguy。文章有描述，有議論，要加敘加議，有血有肉，上下文連貫要緊密，首尾要呼應，人和事要給人們留下深刻印象。

翻譯：
最近，一些地方大學開始將方言列為某些學生的必修課程，學生們要學習當地方言，然后被評分以作為畢業的依據之一。一方面，支持此種做法的人認為，將方言列為必修課可防止其消失，從而使當地傳統文化和文化多樣性得以弘揚，同時城市獨特的個性得以保留。另一方面，反對此種做法的人爭論說，當地學生與外地學生相比有很多絕對優勢，因此將方言列為必修課會引起教育不公平的問題。而且，將方言列為必修課程還會引起一些其他問題，如教材使用、師資問題和考試標準等。在我看來，方言作為傳統文化不可缺少的一部分和一種交流工具，可以讓學生自愿學習和使用，而不是強制完成。
