1. 学生能够了解本单元单词的基本用法。2. 学生能够辨析易混淆词的用法，并能熟练运用。3. 学生能够掌握重点难点词的拓展及其用法。
本节课为unit3 的单词和短语教学，单词本来是零散的，易混的，但是本节课运用了从点到线，从线到面的词汇教学方法，使重点难点单词成了容易掌握的单词块，单词串，从而实现了知识即词汇的重新组合，这一点也符合新的英语教学大纲的要求。 首先，用听本单元的单词录音进行导入，让学生从整体上感知下单词。然后，对重点单词进行讲解，既有对单词用法的拓展，又有对短语释义的延伸。讲解和巩固练习结合，让学生加深理解词汇用法并当堂掌握。而且，练习形式多样化，有翻译，有填空，有选择，从各个角度来对词汇关进行突破。
