中考复习 非谓语动词Class: 3 Class 9 Grade Teacher:朱悲鸿Date: Apr 17th , 2014Topic: 动词不定式（Infinitive）教学目标：1.掌握动词不定式的几种形式2.掌握动词不定式在句子中可以作什么成分 3.掌握动词不定式用法/功能4.掌握运用动词不定式注意事项教学难点：动词不定式用法和几种特殊情况 教学方法：合作，探究式教学教学过程：Step1.通过复习归纳动词不定式的几种形式1.动词不定式的基本形式a. to + 动词原形 b.有时可以不带to(秃头不定式）2.动词不定式的否定形式a. not to do b. not do （why not do ?）Step2. 结合练习题让学生思考：动词不定式在句子中可以作什么成分？学生得出结论：1.作主语2. 作宾语3. 作宾语补足语4. 作定语5. 作状语6. 作表语7. 与疑问词等连用Step3. 讨论动词不定式用法/功能，并总结(1). 作主语To see is to believe.Its exciting to surf on the Internet 作主语的不定式如果很短，通常位于句首；若不定式（短语）较长时，常用it作形式主语，而把真正的主语（即动词不定式）放在后面以避免头重脚轻。(2) 宾语The workers decided to get better pay.常用动词不定式作宾语的动词有：want, hope, wish, refuse, learn, would like, choose, decide, agree, pretend, expect, plan (3). 宾补The teacher told me to clean the blackboard.He often helps me (to) repair my bike.常用动词不定式作宾补的动词有：tell, ask, want, warn, wish, allow, encourage, expect, teach, help(4). 定语I have something to say.动词不定式若在句中作定语，常放在被修饰的名词或代词后。如果不定式中的动词是不及物动词,则要带上与之搭配的介词，构成及物动词短语。Eg:He is looking for a room to live in .(5) 状语He got up early to catch the train.动词不定式作状语主要用来表示目的，原因，或结果等。(6). 表语My job is to help the patient.不定式可以放在be动词后，形成表语。(7) 与疑问词连用He didnt know what to say. (宾语) How to solve the problem is very important.(主语) My question is when to start. (表语)不定式与疑问词who, which, when, how, what 等连用，形成带疑问词的不定式。在句中起名词作用，可充当主语、表语、宾语等。在与why连用时，只用于why或why not开头的简短疑问句中，后面紧跟的动词不定式不带to。 Why do sth.? Why not do sth.?Step4.难点突破：a.不定式的逻辑主语Its good for you to do morning exercises.The question is too difficult for us to answer. Its very kind of you to think of the others.如果要说明不定式表示的动作是谁做的，可以在不定式前加一个for(of)引起的短语。介词for(of)的宾语叫不定式的逻辑主语。即：It+be+adj+for/of+sb+to do sth注：若是形容词是描述不定式行为者的性格、品质的，如kind，good，nice，right，wrong，clever，careless，polite，foolish等，用of,否则用for 。b.形式宾语不定式作宾语时，如带有宾语补足语，则要把不定式放到后面，用it作形式宾语，构成“主语+动词+it+宾补（形容词、名词）+不定式”结构。Eg:He found it very difficult to get to sleepc.在使役动词let，make，have和感官动词see，hear, watch, notice, feel, find等后要用不带to的动词不定式作宾补。但是，当上述动词变为被动语态后，其后的不定式必须补上to。如： We often hear her sing. 我们经常听见她唱歌。 被动语态： She is often heard to sing.Step5.通过练习来加强学生对本课知识的掌握巩固。 Fill in each blank with the proper word from the brackets:1.The teacher often tells us _(not be) late.2.It takes me an hour _(do) my homework every day.3.His parents often make him _ (do) a lot of exercises.4.Your skirt is nice.
