教学课题：M5U3 Grammar and usageVerb-ed form and verb-ed phrases教学背景：本单元学生将掌握过去分词和过去分词短语在句中形式意义，几种语法功能和四个考点例析。
对于它们在句中的不同功能学生要能区分掌握。
本课时将利用本校特色教学—分层次问题教学的方式使学生在自学质疑﹑交流展示﹑互动探究精﹑讲点拨和迁移应用的教学模式中顺利完成本科室的教学目标。
教材分析：高二第一学期要求学生全部掌握分词的用法，而本单元作为分词板块的最后一个单元，采用比较直接的方法从现在分词的用法回顾导入课题，首先是考虑到知识的延续性，同时动词的现在分词形式在进一步学习动词的过去分词的过程中起到了不可忽视的对比作用。
再者，考虑到学生在高中英语学习的过程中对于分词已经有了一定程度的了解，因此在本单元语法第一板块的教学中主要采用启发式回顾、对比、总结然后操练的方式，让学生熟悉并能运用过去分词在句中所充当的定语、表语、宾语补足语等成分。
教学方法和策略：全班被分成六个小组，以讨论的形式，合作探究参与教学活动，并由小组代表展示小组成果。
教师在适当的时间和环节结合PPT进行精讲点拨。
Teaching aims:（教学目标）1. Enable the Ss to master the usage of verb-ed form and verb-ed phrases2. Enable the Ss to identify the difference and usage of verb-ing and verb-ed as adjectivesTeaching important and difficult points:（教学重难点）1.The consolidations of each part which should be finished by the Ss independently.2.The related exercises should be finished fluently.Teaching procedures:（学习过程）StepⅠLead-in（分层次问题学习A类问题）This section needs 7 minutes. Ask the Ss to watch the following sentences and do conclusion to fill in the blanks through discussion .Then, one group gives the answers. At last, the teacher checks the answers by PPT and gives relative explanation.①Mum threw away that broken cup.②The boy named Tom will come here tomorrow.③Edison became interested in science when he was very young.④When I returned home, I found my wallet gone.⑤When completed, the museum will be open to the public.⑥Excited by the new discovery, we decided to go out and celebrate.⑦Given more time, we could do it much better.⑧The boy sat at the table buried in his homework.【总结】(1)以上①②③④句中划线的过去分词在句中担当什么成分？句中做定语，句中做表语，句中做宾语补足语。
(2) 单个V-ed词作定语时，一般置于被修饰名词之_____，分词短语做定语时，则一般置于被修饰名词置于名词之_____。
(3)以上⑤-⑧句中的过去分词分别充当什么状语？分别为：⑤，⑥，⑦，⑧【设计意图】作为对本课时的导入，利用八个包含过去分词四个语法功能的句子，使学生在自学质疑中试着自主地总结出它的语法功能。
能够使学生在思考中带着问题进入本课时语法学习。
学生要展示自己的总结，教师作必要纠正点拨。
StepⅡ过去分词的形式和意义（分层次问题学习A类问题）This section needs 3 minutes. The Ss are required to fill in the blanks and one student from one group to give the answers. Then, the teacher checks the answers by PPT.1.形式：过去分词只有一种形式，即；其否定形式为2.意义：及物动词的过去分词表或；不及物动词的过去分词只表，不表【设计意图】要了解过去分词的语法功能，要先明确其表达的意义和具体的形式，才能在具体理解掌握它的用法时做到精准和区分。
学生要自行总结和解释，教师辅助之。
StepⅢ过去分词的语法功能（分层次问题学习C类问题）This section needs 25 minutes. First, each group has a discussion and has a communication with its own group members and other groups. Second, fill in the relative blanks and finish the related exercises. Third, present their answers by 4 students from 4 groups. At last, the teacher checks the answers by PPT and gives relative explanation.1: Attribute(定语)the injured woman= the woman who was injuredthe escaped criminal= the criminal who has escapedfallen leaves=leaves which have fallenthe name mentioned in the letter= The name which was mentioned in the letter【总结】单个V-ed词作定语修饰名词一般置于名词之_____，V-ed词组修饰名词则置于名词之_____，相当于一个________从句。
【注意】1.有些单个的过去分词，像left(剩余的)，concerned(有关的)等，习惯上作后置定语。
例：standing room left所剩的立足之地the people concerned有关人士2.过去分词修饰something, anything, everything, nothing, anybody, somebody, nobody, everybody等不定代词或不定代词those时，要放在这些词的后面【当堂检测】Rewrite the following sentences with attributive clauses.1.

The meeting, attended by one thousand students, was a success.2: Predicative (表语)例句：1) Edison became interested in science when he was very young.2) The little boy was very excited when he heard that he could go to the party. 【总结】过去分词作表语，置于连系动词：be, seem, appear, look, sound ,feel, remain, stay, become…之后，通常表示主语的心理感觉或所处的状态,相当于______词,其主语通常是人.【观察】以下两个句子是系表结构还是被动语态？1）The book is well written.（）2）The book was written by Lu Sun..（）【总结】由过去分词构成的系表结构，强调主语的特点或所处的状态；构成被动语态的过去分词，则强调动作。
3. Object Complement(宾语补足语)1) As he knows little English, he finds it difficult to make himself understood.2) I had my hair cut yesterday.3) He sat there, with his hands tied behind.【总结】1.做补语的过去分词一般都来自及物动词，和宾语有逻辑上的关系。
2.可用过去分词做宾语补足语的有：①表示感觉和心理状态的动词：see, hear, notice, watch, find, feel, …；②使役动词：get, have, make, leave, keep…；③with 的复合结构。
