动词不定式详细讲解学案
动词不定式(Infinitives)动词不定式的形式：一、动词不定式的时态如果不定式所表示的动作与主要谓语动词所表示的动作同时（或几乎同时）发生或发生在主要谓语之后，通常用不定式的一般形式。
如：I saw him go out. I’m glad to see you.1.如果不定式所表示的动作发生在主要谓语动词或特定的时间之前，不定式就要用完成式。
如：I intended to have telephoned you, but I forgot to. I should like to have bought a dictionary.2.不定式进行式表示主要谓语动词所表示的动作发生时，不定式所表示的动作正在发生。
如：I am glad to be talking with you. She pretended to be listening attentively.3.不定式完成进行时表示的是一个开始于过去某一时刻但一直延续到谓语动词发生的那一时刻的动作。
如：He was thought to have been working on the project for two years.(1). They pretended not to see us. (一般式表示与谓语的动作同时/几乎同时/发生在它之后.)(2). He pretended to be sleeping. (在谓语动词发生的同时,不定式的动作也正在进行)(3). She pretended to have known it before. (完成式表示动作发生在谓语动作之前)(4). We’re happy to have been working with you.(完成进行式表示谓语动作发生之前,不定式的动作一直在进行而且可能之后也继续)二、不定式的被动语态当不定式的逻辑主语是动作的承受者（和不定式相关的名词或代词与不定式中的代词存在被动关系）时，这个不定式要用被动式，包括它的各种时态在内。

动词不定式的用法(学案)
动词不定式的用法非谓语动词是指那些在句中不能单独充当谓语的动词，可分为不定式，动名词，现在分词和过去分词。
1. 不定式形式:由to＋动词原形构成。
2.用途：在句中不能作谓语。
它具有动词的性质，本身可以带宾语和状语。
动词不定式在句中除了不做谓语，可以作句子任何成分。
动词不定式的被动形式除了一般形式外还有其完成式和进行式。
动词不定式及其短语还可以有自己的宾语、状语，虽然动词不定式在语法上没有表面上的直接主语，但它表达的意义是动作，这一动作一定由施动者发出。
动作的施动者我们称之为不定式的逻辑主语，其形式如下：主动形式被动形式一般式（not）to make （not）to be made完成式（not）to have made （not）to have been made进行式（not）to be making(1)语态如果动词不定式的逻辑主语是这个不定式所表示的动作的承受者，不定式一般要用被动语态形式。
如：It's a great honor _____________ (invite) to Mary's birthday party.（不定式作______）I wish ______________ (send)to work in the country.（不定式作__________）Can you tell me which is the car________________( repair)?（不定式作________）He went to the hospital______________________ (examine).（不定式作__________）(2)时态1) 现在时：一般现在时表示的动词，有时与谓语动词表示的动作同时发生，有时发生在谓语动词的动作之后。
I hope_________(see) you again. = I hope that I'll see you again. 我希望再见到你。

Step2.请学生思考：动词不定式在句子中可以作什成分？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 5.作状语6.作表语7.与疑问词等连用Step3.出示幻灯片让学生根据总结结果加强记忆。
Step4.讨论动词不定式用法/功能，并总结：(1).作主语To see is to believe.It’s 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I want to go home.The workers decided to get better pay.I found it necessary to talk to him again.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 …He found it very difficult to get to sleep 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。
学案2：不定式
不定式(The infinitive)情景探究观察上面句子, 并说出画线部分的作用①不定式作_______________。
②不定式作_______________。
要义详析动词不定式由“to+动词原形”构成。
这里的to是不定式标志, 没有词义。
不定式具有名词、形容词或副词的某些语法功能, 又有动词的特点, 可以有自己的宾语和状语, 构成动词不定式短语。
一、动词不定式的时态与语态*I plan to attend the meeting to be held tomorrow.我打算参加明天举行的会议。
(attend的动作在plan之后发生, 且meeting与hold之间为被动关系)*They are said to be studying psychology.据说他们正在研究心理学。
(be said与study同时发生)*I’m very sorry to have kept you sitting around doing nothing.让你一直无所事事闲坐着我很抱歉。
(keep发生在be sorry之前)*No harm seems to have been done.似乎并没有什么危害发生。
(do发生在seem之前, 且harm与do之间是被动关系)*She is known to have been dealing with the problems for many years. 大家知道她处理这类难题已经有很多年了。
【名师点津】不定式的“被动”与“否定”(1)不定式的被动式表示其逻辑主语为不定式动作的承受者。
*It’s a great honour to be invited to Mary’s birthday party.被邀请参加玛丽的生日聚会是一件非常荣幸的事情。
(2)不定式的否定式通常是将否定词not或never置于不定式之前, 即构成not to do 或never to do 这样的形式。
