学生,尤其是中学生,参与社会实践的机会少,获取的写作材料大都是书本上、课堂上的间接的旧材料。这些旧材料大都是前人用过的,我们再拿来写作,必须从中发掘出新的思想,否则便是炒别人的“熟饭”,索然无味。如何从旧材料中发掘新思想呢?笔者以为应从以下几个方面下功夫。一、反面材料正面看许多事物(人物),由于时代的局限和传统观念的思维定势,人们一直贬抑它们,把它们看着是反面的东西。《水浒传》中的武大郎,仅仅因为他生理上的缺陷,身材矮小,人们便瞧不起他,说他是三寸丁谷树皮,卑劣猥琐,甚至诽谤说武大郎开店 Students, especially middle school students, have few opportunities to participate in social practice. The writing materials they obtain are mostly indirect old materials in books and classes. Most of these old materials were used by the predecessors. We must use them to create new ideas. Otherwise, we will fry others’ “cooked rice” and be boring. How to discover new ideas from old materials? The author thinks that he should work hard from the following aspects. First, the negative side of the material to see many things (characters), due to the limitations of the times and the traditional concept of mindset, people have always devalued them and looked at them as negative things. Wu Dalang in the “Outlaws of the Marsh” was only short because of his physical defects. People looked down on him and said that he was a three-inch Ding Gu tree bark.
