《课程标准解读》
词汇是语言学习的基础,是构成语言的最基本要素。要掌握好、运用好一门语言,必须具备丰富的词汇。新课程背景下的高中英语教学对词汇教学方面有了较高的要求。首先是总量激增。其次提倡从用的角度出发来学习词汇。运用词汇理解和表达不同功能、意图和态度,运用词汇给事物命名、进行指称、描述行为和特征、说明概念等。这说明对词汇学习的要求不仅仅限于辨认、识记和理解,还在于运用和表达:词汇教学不仅要求扩大学生的词汇量,还要求提高学生运用已知词汇的熟练程度。除此之外,新版教材中出现了很多新型词语,语言素材广泛,涉及各个领域,给词汇教学带来了很大困难。
传统的教师讲单词、学生背单词的教学模式已不适应新课程的目标和要求。因此,积极探索符合新课程理念的词汇教学方法和策略,已成为每个英语教师义不容辞的职责。

《课程标准解读》
语言学家吕叔湘说过:“词语要嵌在上下文里头才有生命,才容易记住,才知道用法。”任何词汇的使用都离不开具体的上下文语境。如果仅把词汇看成一个个彼此孤立的单位来学习,那就会只见树木,不见森林。记忆难度大。但如果将单词放在句子中去记忆,则既能引起学生对英语的兴趣又能轻松背单词,还能提高口语能力。因此,通常在讲解单词的时候,笔者都是给出一个句子或者是短语,让学生能够通过语境记住单词的意思。有时,也可以先给出句子,然后让学生根据句子猜测词义,印象会更深刻。同时,指导学生复习时应该通过复习句子,熟读课文来记住单词的意思。
