新人教版B3U4动词不定式教学设计Part1：Analysis of teaching material该板块的活动主题是“描述关于太空的事实以及人类探索太空的努力”。无论是在口头表达还是笔头表达中，无论是从语义建构还是语用功能上看，不定式做状语和定语的用法都很常见。这一板块就是为了让学生掌握并运用这一结构描述已知的太空事实，太空探索历史上的重大事件和重要人物的成就。Part2：Analysis of this period 本课例是语法教学，主题是动词不定式做定语和状语。旨在帮助同学们能对动词不定式有个系统化的学习和理解，因为本课会把动词不定式做主语，宾语，表语，定语，状语和宾语补足语放在一起学习。在单元主题的引领下，如何把语法教学和单元主题联系在一起，便成了我的重点考虑：如何让学生在了解语法的同时，又能够自主探究，正确运用，从而达到真正实现语法学习的最终目的：能够在语境中有效地运用语法知识。Part 3: Analysis of students本节课授课对象是高一学生，经过高一近一年的学习，词汇量大增，听说读写也有了一定的语言技能。学生在初中阶段已经学习过不定式用作目的状语，本课增加了不定式做其他句子成份的用法。语法课是帮助学生具体语境中感知语法规则，并在实践中合理运用。Part 4: Learning objectives这节课后，学生能够：辨别动词不定式在意义和用法上的不同；掌握动词不定式的功能和形式； 能够基于语境迁移运用，正确使用不同的非谓语动词形式。Part 5: Teaching proceduresActivity 1: Observe the sentences carefully and mark the usages of the infinitives:1.
