2009年上学期樊家庙中学九年级英语学科学教稿 主备教师 李柳贞 集体备课成员 王勇 学生姓名 备课时间 5月6日 集体研究时间 主管行政 教学内容 动词不定式的形式和用法 课时安排 共1课时 教学目标 掌握动词不定式的基本形式和用法 教学重点 动词不定式的用法 教学难点 动词不定式的用法 学法指导 讲练结合 预习导学 阅读八年级下册有关动词不定式的用法 课堂研讨 一、动词不定式分_______和___________两种。带to 不定式由_______构成,其否定形式为_______;不带to不定式与______同形。 二、不定式的用法 动词不定式在句中可作主语、宾语、宾补、表语 、定语、和状语。判断下列动词不定式的用法: 1.To learn English is not an easy thing . ( ) 2.It is our duty to learn the knowledge well.( ) 3.He wants to visit Nanjing . ( ) 4.I expect you to write to me .( ) 5.To see is to believe .( ) 6.Is there anything toeat ?( ) 7.My little sister is too young to go to school .( ) 8.My job is to plant cotton . 9.I asked him to show me his new dictionary .( ) 10.He has no house to live in ( ) 三、注意几点 1.不定式作主语时,常用it 代替不定式结构,it被称为形式主语,作为句子真正主语的不定式后置。常用句型:It’s +adj./n.+for /of sb. +to do sth.形容词表示做事情怎样用for 引出不定式的逻辑主语;形容词表示人的特点或性质则用of引出不定式的逻辑主语。如: It’s important _____us ____learn English well . It’s very nice ______you _____help me . ___is hard to say .A.This B. It C.That 2. 常接不定式作宾语的动词有want,hope ,refuse ,would like,help,decide,wish,plan,等等。 The teacher decided _________a speech at that time. 3. 不定式作定语与被修饰的词是动宾关系,所以动词要用及物动词,如果为不及物动词则要接介词。 He is a man to depend on .(on不能省) He has no house ____________ A. to live B.to live in C.live in 4. 常接不定式作宾语补足语的动词有want,ask ,tell,wish,would like ,get,encourge, allow,invite等。但在使役动词make ,let,have和感官动词see,hear,watch,notice,feel等之后,要把作宾补的不定式结构中的to省略。 1)I often hear Tom ________in the next room.

But the teacher’s smile made her _____better . A feel B to feel C fall D to fall 5.疑问句+不定式 不定式可以和疑问词who ,what,which,why,when,how,where等连用,构成“疑问词+不定式”结构,通常用于 下列动词之后:tell,teach,know,wonder,learn,show,find,out,ask,understand等等。 1).We are going for a picnic tomorrow.I’ll call Wendy to make sure ____ A.why to start B.when to start C.what to start D.which to start 2).

(2)remember to do sth./remember doing sth (3)forget to do sth./forget doing sth. (4)go on to do sth./go on doing sth.
