补全对话是考查交际会话能力的主要题型.它可考查课标和教材中出现的所有交际功能项目, 如打电话, 谈论天气, 度假, 看病, 购物等。强调了语境的作用，加大了对语言运用能力的检测力度。内容上更加接近学生日常生活，在一段对话中留出若干空白，要求学生从所给的选项中选出恰当的句子或填写合适的单词，使补全后的对话完整、通顺、意义正确。它要求学生根据上下文的逻辑关系，在整体把握对话的基础上，去分析、判断与综合，初步考查学生口语运用的能力。有利于考察学生理解和应用英语知识的能力。复习和解题中要注意以下几点:
1.通读对话全文，摸清对话发生的地点、时间，人物的身份，对话的内容。
2.理清上下句的逻辑关系，使你填入的话和整篇对话文理通顺，融为一体。答题时, 依据语言环境补全对话，逐句推敲。
3.符合说英语国家人的习惯。答题时，语言要得体，表达要地道。要注意口语交际中的一些习惯用语，特别是汉语和英语表达方式的不同，要认真通读对话。
4.应将一些常见情景下经常运用的句型，词组背熟。比如:看病, 问路, 邀请等常规用语。
5.注意空白处的标点。是问号，就应填问句；是句号，就应填陈述句。
