1、Unit4 Body LanguageGrammar本课件主要介绍动词-ing形式作定语和状语，做练习启发学生思考，通过示例引导学生总结出动词-ing形式在什么情况下作状语或定语。举例说明如果动词-ing形式出现在名词前后，并修饰该名词，一般作定语，该定语可变为介词短语或定语从句。举例说明如果动词-ing形式用于修饰某动词或整个句子时作状语，可变换为状语从句。作状语时对谓语起修饰和陪衬作用，表示时间，原因，条件，让步，结果，方式或伴随情况。最后让学生做练习，题型涉及造句，填空，改错和单选，让学生当堂完成，及时巩固。Grammar一一:V-ing:V-ing 形式由形式由“dodoinging”
