Unit 2 I'll help to clean up the city parks. SectionA (2d&Grammar Focus-4c ) 课时教学设计
课型 听说+语法课 课时 1
教材分析
本课时主要是本单元的语法部分，语法结构较为繁杂，教学压力相对较大。因此，将本单元的重点语言结构分散到本单元不同部分进行教学。例如：Section A的1a-1c的教学建议提及了could表示建议的功能，2a-2c活动的教学已囊括了动词短语的初步介绍，而在3a-3c的教学建议里已包含了对动词不定式的学习。在本课，通过不同形式的练习，可帮助学生梳理巩固。
学情分析
通过第一课时的学习，学生讨论和分享了参与志愿服务工作的方式，巩固了对动副短语用法的理解，深化了对本单元话题（Offering help）的感知。本课时阅读材料脉络清晰，层次分明，生词不多，学生没有很多理解层面的障碍。对于动词不定式，学生之前主要当做词组来记忆，需引导其加强对句子的分析，才能进一步理解动词不定式的作用。
课时教学目标
语言能力：能够在多个语篇创设的情境中正确使用动词不定式和短语动词，理解和表达他人与自己热心公益和志愿服务的意愿和经历。 学习能力：能在学习活动中积极与他人合作，共同完成学习任务；能在学习过程中积极思考，主动探究，发现并尝试使用多种策略解决语言学习中的问题，积极进行拓展性运用。 思维品质：能够在老师的引导下，通过观察、讨论、归纳等课堂活动，探究动词短语和动词不定式的语言规律，提高思维的逻辑性和深刻性，加强语言表达的准确性。 文化意识：能够了解国外的同龄人所参与的志愿服务活动，从而懂得关爱他人、服务社会的价值和意义，热心公益。
教学重难点
教学重点：正确使用动词不定式表达意愿，初步感知动词不定式在句中的多种角色；掌握文章出现的生词，达到熟练运用的目的； 教学难点：动词不定式在英语句子中的成分与作用。

Task5:Role-play Step 3：Grammar focus 探究一:动词不定式（infinitive） 1.定义:动词不定式是非谓语动词的一种，它没有人称和数的变化，在句中不能直接作谓语。 2.构成：动词不定式的基本形式是“to+动词原形”，常写作to do(有时to可以省略)。 3.用法：动词不定式具有名词、形容词和副词的特征，因此可在句中作主语、宾语、宾语补足语、定语、表语和状语等。 1).作主语 一般位于句首，谓语动词用单数形式。 为了避免句子“头重脚轻”，往往用it代替不定式作形式主语，而将不定式放在后面作真正的主语。 作宾语 We decide to plant trees this weekend. I want to be a volunteer. Lily wants to find a job as an English teacher in Beijing. 3)作宾语补足语:动词不定式用来补充说明宾语的情况。 Our teacher asked us to clean the classroom after school.

When I passed the classroom, I saw them singing. 注：see sb. do sth. 意为“看见某人做某事”，表示看见了事情的全过程或者多次看见。宾语补足语的动作已完成，动词用省略to的不定式。see sb. doing sth. 意为“看见某人正在做某事”，表示宾语补足语的动作正在进行，动词用动名词形式。 使役动词(make, let, have)后接不带to的动词不定式作宾语补足语。 My parents make me do some housework. help后面的动词不定式可加to，也可不加to。 Could you help me (to) carry the box 4）做表语：动词不定式做表语常用于以下结构： My/Her/His job/dream/goal/aim is… My dream is to be an astronaut. Her job is to look after sick children. 5）作定语 6）作状语 To keep healthy, he runs in the park every day. We should work together to save the Earth. 目的状语:动词不定式可表示某一动作或状态的目的，位于句首或句尾。 探究二：短语动词（Phrasal verbs） 1.动词+介词 介词后须有宾语，宾语位于介词后。介词有：for, after, about, of, with, at... wait for 等待 laugh at 嘲 look after 照顾 agree with 同意 2）动词+副词 副词有： up, out, down, off, away, in... give away 捐赠 hand out 分发 put up 举起；张贴 put off 推迟 3）动词+副词+介词 相当于及物动词，宾语总是位于介词之后 come up with 想出 look forward to 盼望 get on with 和睦相处 4）动词+名词 have a cold 感冒 make a difference 影响；有作用 take a walk 散步 5）动词+名词+介词 take part in 参加 pay attention to 注意 make friends with 交朋友 Step4.
