1. 引言
《普通高中英語课程标准(实验)》中八级词汇知识目标之一为:学会使用3300个左右的单词和400-500个习惯用语或词语搭配(教育部,2003)。词汇是语言三要素之一,它维系着语音和语法,是构筑语言结构和意义的基本单位。没有语法,表达甚微;没有词汇,表达为零(Wilkins,1972)。由此可见词汇教学的重要性。
教材中的词汇通常可分为两个层次:第一层是核心词汇;第二层是非核心词汇即认知词汇。对于认知词汇,学生会认读,了解其词义、词性即可;而对于核心词汇则要求学生不但能在听和读的过程中感知词语形式并提取其意义,还要求在说和谐的活动中有能力输出这些词汇(葛庆波,2012)。因此,词汇教学的重点要放在核心词汇上。
在词汇教学领域,很多专家和教师都提出过有效的方法,如任务型词汇教学法、话题词汇教学法、游戏竞赛法、自主探究法、归类记忆法和例句记忆法等(魏恒健,2007)。而实际上词汇教学大都形式单一,“领读——跟读——讲解——背诵——听写”,词汇学习枯燥无味,事倍功半。只有高度化的语境才能充分展示词汇的语义、句法和搭配特征等深度知识(张文忠、吴旭东,2003)。因此,教师应当创设语境进行词汇教学。
