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 adjectives Teaching 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）Step Lead-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.Mum threw away that broken cup. The boy named Tom will come here tomorrow.Edison became interested in science when he was very young.When I returned home, I found my wallet gone.When completed, the museum will be open to the public.Excited by the new discovery, we decided to go out and celebrate.Given more time, we could do it much better.The boy sat at the table buried in his homework.【总结】(1)以上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-句中的过去分词分别充当什么状语？分别为： ， ， ， 【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。Step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。Step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. They took the injured woman to the nearby hospital at once._ _ 2. The firemen were trying to rescue the people trapped in the fire. _ _ _ 3. The books, written by Lu Xun, are popular with many Chinese people. 4. 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：表示感觉和心理状态的动词：see, hear, notice, watch, find, feel, ；使役动词：get, have, make, leave, keep；with的复合结构。4.Adverbial in sentences（过去分词作状语）1). 作时间状语, 相当于时间状语从句 (常同连词when, whenever, while, once, until等连用)Seen from the hill, the park looks very beautiful.= When the park is seen from the hill, it looks very beautiful.Once seen, it can never be forgotten. = Once it is seen, it can never be forgotten.2). 作原因状语，相当于原因状语从句。Lost in thought, he almost ran into the car in front of him.= Because he was lost in thought, he almost ran into the car in front of him.3). 作条件状语, 相当于条件状语从句Given more time, we could do it much better.= If we were given more time, we could do it much better.Unless invited to speak, you should remain silent at the conference.= Unless you are invited to speak, you should remain silent at the conference.4). 作伴随状语, 相当于并列句The girl lay in bed lost in thought. = The girl lay in bed and was lost in thought. The boy sat at the table buried in his homework.= The boy sat at the table and was buried in his homework. 5)作方式状语,相当于方式状语从句The plan gets on well as planted/expected.【设计意图】本环节设计过去分词的四个语法功能的讲解展示。每个环节都旨在通过例句的直接呈现，让学生观察理解后自己总结出它的具体用法规则，然后即时设置相关题目当堂巩固训练，使学生在独立思考完成中稳扎稳打完成每一个语法功能的掌握和运用。Step 充当形容词的现在分词和过去分词的区别（分层次问题学习B类问题）This section needs 3 minutes. The Ss have a short discussion and then give their answers. Then the teacher checks the answers by PPT and gives relative explanation.例句：1）The news was really exciting. 2）She was too disappointed to say a word. 【总结】现在分词常用来修饰 ，说明主语的性质或特征，意为令人；过去分词用来修饰 ，说明主语所处的状态，意为感到【注意】过去分词也可修饰与人直接有关的事物。如：expression, look, face等。例：The boy looked up with a pleased expression.【设计意图】在实际问题中，学生往往会混淆现在分词和过去分词的意义和用法，所以在学生已经掌握现在分词的基础上有必要在本课时学习过去分词后对两者进行区分掌握。Step 考点例析（分层次问题学习C类问题）This section needs 7 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.考点一：done, to be done和being done做定语的区别试比较：a bridge built last year a bridge to be built next year a bridge being built now【总结】 做定语表示一个被动或完成的动作；不定式一般式的被动语态表示一个 的动作；现在分词一般式的被动语态表示一个 的动作。【考题印证】1. (2010北京卷)Im calling to enquire about the position in yesterdays China Daily.A. advertised B. to be advertised C. advertising D. having advertised 2. (2010全国卷) Mrs. White showed her students some old maps from the libraryA. to borrow B .to be borrowed C. borrowed D. borrowing考点二：过去分词做状语的用法过去分词做状语，其逻辑主语通常就是句子的主语，且主语是过去分词动作的承受者，也就是说，过去分词与句子的主语之间是被动关系。【考题印证】(2010陕西卷) _ from the top of the tower, the south foot of the mountain is a sea of trees . A. Seen B. Seeing C. Have seen D. To see考点三：在with的复合结构中，过去分词做宾语补足语与其他非谓语动词做宾语补足语的区别在with复合结构中，过去分词做宾语补足语与宾语之间是被动和完成的关系；现在分词与宾语之间是主动关系；而不定式表示将来发生的动作。(2010山东卷) The living room is clean and tidy, with a dining table already _ for a meal to be cooked.A. laid B. laying C. to lay D. being laid考点四：系动词后接过去分词做表语的用法表状态的系动词如remain等后接过去分词做表语构成的系表结构强调主语的特点和所处的状态，此时，过去分词已形容词化。1. (2010福建卷) In April, thousands of holidaymakers remained abroad due to the volcanic ash cloud.A. sticking B. stuck C. to be stuck D. to have stuck2. (2009四川卷) Ladies and gentlemen, please remain _ until the plane has come to a complete stop.A. seated B. seating C. to seat D. seat【设计意图】对于过去分词的学习最终是要升级到具体问题的应用中，所以本环节对过去分词经常涉及的考点例题进行呈现说明，通过考点说明，思考总结和考题印证使学生在理解思考中对每个考点进行掌握和应用，使学生从理论的学习上升到解决考题的高度。Step Homework(分层次问题检测)This section needs 10 minutes after class.
