例如,略读和寻读能力是高中学生必须具备的重要阅读技能,这两种技能都要求学生在快速阅读中捕捉关键词。笔者在课堂上常常利用段落阅读与找关键词相结合的形式提高学生的略读和寻读能力。例如,在教学环节中,老师可以先给学生展示一段已标出关键词的段落:When the Romans invaded Britain in AD 43 and conquered a large part of the island, they encouraged the leading Celts to adopt Roman customs, to live in fine houses and to enjoy Roman cookery. The Roman cook had many advantages. He did not have to prepare everything himself. Bread came from the bakery, meat from a skilled butcher and other things could be bought ready to use. 然后,教师隐去未划线的句子,让学生根据划线的关键词复述段落大意,体会关键词在提炼句意中的作用。接着,教师可以要求学生仿照这种方法划出所学课文中某个段落的关键词,并用这些词概括本段大意。或者,教师可以在让学生阅读一篇有较多生词但并不影响学生理解大意的文章,并进行标注关键词、归纳文章大意、推测文章标题、讨论文章的写作对象等多种多样的活动。
