  │ 写作点拨 写作点拨 开放作文与传统意义上的写作形似而神不似,是一种全新的写作形式。随着高考英语改革进程的不断深入与发展,相信英语写作的命题形式也会日趋灵活与开放。开放作文更能反映出考生的真实写作水平。 开放作文属于非控制性写作,与传统意义上的写作有所不同。开放作文的题目主要为简短的文字提示或图画,这给考生留下了很大的自由发挥和想象的空间。但也对考生提出了更高的要求,它不仅考查考生的语言表达和组织能力,更考查考生的逻辑思维和想象能力,同时还从多角度考查考生分析和解决问题的能力。 开放作文侧重考查两种文体:记叙文和议论文。记叙文体的开放作文往往给考生一段材料,要求考生根据所给材料的内容,运用逻辑推理的方法,给故事添加开头、发展过程及结尾;议论文体的开放作文逻辑性强,要求考生在所给材料或图画的基础上提炼观点,进行论证,并得出结论。写作时要遵循以下写作技巧: 第一部分:阐述图画中的内容与主题。仔细观察,认真审题,通过审题确定文章的主题、时态和体裁。 阅读写作(二十二)

  │ 写作点拨 第二部分:结合考生的生活或学习情况,阐明图画的寓意及其对我们生活的启示。要紧扣图画信息的主题,进行合理的阐述,并表达自己的感想。在这一部分,只需用简单的语言讲出道理即可,没有必要过深地挖掘图画信息,但要保证文章思想是健康的、积极向上的。
