具体内容：（一）构成和用法其形式是“to+动词原形”。to是不定式符号，无词义。其否定式是在to前面加上not, never等否定词。 不定式可以有自己的逻辑主语，由for引出，加在不定式短语前面。    所谓逻辑主语，就是指非谓语动词等动作的执行者。由于非谓语动词等带有动词的特征，但又不是谓语动词，所以这个动作的执行者就不能称为主语，而在逻辑上又是这个动作的执行者，所以就称为逻辑主语。如果不定式逻辑上的主语是这个不定式所表示的动作的承受者，这个不定式一般要用被动语态。疑问词（who, whom, whose, what, which, when, where, why, how还包括whether）等后面加不定式构成不定式短语，可做主语，表语，宾语等。 1. 作主语。 在不定式短语作主语的句子中，往往用it作形式主语，而不把不定式短语放在句子的后面。如：to die like that is a terrible thing. =it is a terrible thing to die like that. 像那样死去是一件可怕的事。（it作形式主语，把真正的主语to die like that放在后面）.to know oneself is difficult. =it’s difficult t know oneself. 有自知之明不容易。to tell a lie is not always easy. =it’s not always easy to tell a lie. 撒谎并非总是容易的。never to offend anyone is my principle. 永远不得罪任何人就是我的原则。it’s against nature to remain single.保持单身是违反自然的。12345678910111213to see is to believe.眼见为实。for a dog to die like that is a terrible thing. =it is a terrible thing for a dog to die like that. 一条狗像那样死去是一件可怕的事。（for a dog是不定式的主语）for one to know everything is impossible. =it’s impossible for one to know everything. 一个人什么都知道是不可能的。for his brother john to go to sea seems natural. =it seems natural for his brother john to go to sea. 他兄弟john去当水手是很自然的事。it’ll be a great shame for you to forget her. 你要是把她忘了，那可太不应该了。it’s not proper for us not to accept the invitation. 我们不接受邀请不合适。（否定）it has not yet been decided when and where to discuss her resignation. 何时何地讨论她的辞职还没定。但是，下列形容词做表语时，不定式的逻辑主语由of引出：careless粗心的，clever聪明的，cruel残忍的，foolish愚蠢的，good好的，kind好心的 ，naughty淘气的，nice好的，polite礼貌的，right正确的，rude无礼的 ，silly愚蠢的，stupid傻的，unwise不明智的，wise明智的，wrong错误的，等等。为什么这些词要用of引出不定式呢？因为这些形容词都是描写人的性格和特点的形容词。“it is + 形容词 ＋of sb.+ to do sth.”这样的句型更强调某人如何如何，可以改写为：“sb. + be + 形容词 + to do sth.” 而“for sb. to do sth.”这一结构更强调做某事如何如何。例如：it is unwise of you to go to the united states at this time. =you are unwise to go to the united states at this time. 强调你不明智。而 “it is difficult for you to learn english.”更强调学英语很难，不能写成you are difficult to learn english. （这句话含有逻辑错误。）it’s very kind of you to come to see us off. =you’re kind to come to see us off. 你来为我们送行太好了。it’s unwise of him to drink and smoke so much. =he is unwise to drink and smoke so much. 他喝这么多酒抽这么多烟是不明智的。it’s extremely cruel of john to kill animals. john杀害动物真是残忍之极。it’s rude/polite of jack to say this to her. jack对她说这个，很无礼/不礼貌。 2. 作宾语及宾语补语。（1） 有些及物动词常用动词不定式作宾语。常见的这类动词有：afford负担得起，agree同意，arrange安排，ask要求，attempt试图，beg乞求，begin开始，choose选择，claim声称，consent同意，dare敢，decide决定，decline谢绝，desire欲想，demand要求，determine决心，expect期待，fail失败，forget忘记，hate讨厌，help帮助，hope希望，intend打算，learn学习，like喜欢，long渴望，manage设法，mean打算，need需要，offer主动提出，plan计划，prefer更喜欢，prepare准备，pretend假装，promise答应，refuse拒绝，remember记得，seek寻求，seem好像，tend倾向，threaten威胁，undertake承担，volunteer志愿，want想要，wish希望等。例如：i

holidays.关于去哪里度假，她刚才征求了我的意见。（3） 有些动词需要不定式作宾语补足语。这种动词常见的有：ask请求，advise劝告，allow允许，beg乞求，believe相信，call on号召，cause促使，compel强迫，command指挥，direct指导，enable使…能够，encourage鼓励，expect期望，feel觉得，force迫使，get使得，hate不喜欢，have使，hear听见，help帮助，inspire鼓舞，intend 打算,invite邀请,instruct指示，know知道，lead引导，let让，like喜欢，listen to

happen.一位警察看见事故发生。we listened to her talk about her experience abroad. 我们听她讲国外的经历。we’d be glad to have you work with us. 我们会很高兴有你和我们一起工作。上述help后面的不定式省掉to与保留to都可以。在被动语态中，上述动词后面的不定式要把省去的to还原。例如：12345678910111213i heard the dog come in. =the dog was heard to come in.我听见那条狗进来。   有人听见那条狗进来。i saw her go out by bike.    =she

干吗冒犯法的险呢？12345678910111213（5）不定式作宾语而后面还有宾语补语时，常用it来代替不定式短语，而把真正作宾语的不定式短语放在补足语后面。常见的动词有：consider认为，feel觉得，find发现，make使，think认为，等等。例如：i think it best to go. 我想最好走。do you consider it right to send our doctors over? 你觉得派我们的医生去对吗？i found it strange for her not to come today.我发现她今天没来是很奇怪的。注意：hope希望，demand要求，suggest建议，这三个词不能跟不定式作宾补。错：i hope you to be happy. 我希望你快乐。i suggest you to take him

glad to have met your parents here. 我很高兴在这儿见到了你父母。（已见过）    i’m sorry to have kept him waiting for me so long.我很抱歉让他等了我这样久。（已经等过了）动词不定式的完成式和下列动词的过去时连用，表示过去没有实现的事情：plan, hope, expect, be, intend, mean,

didn’t. 他原计划上周出国的。i’d like to have been offered the job and（to have been）given the opportunity to prove myself.我真想（当时）把这个工作给了我，给我个机会让我证明我自己。同样的意思也可用上述动词的过去完成时加动词不定式的一般式来表达。例如：i had hoped to visit the great pyramid. =i hoped to have visited the great pyramid. =i hoped to visit it, but i didn’t. 我本希望参观大金字塔的。they would have liked to have your help. =they would like to have had your help. =they wanted to have your help but they didn’t have it. 他们本想得到你的帮助的。不定式的被动语态。当不定式的逻辑主语是这个不定式所表示的动作的承受者时，不定式一般要用被动形式。不定式的被动形式有两种：一般式：to be+过去分词完成式：to have been+过去分词you’re lucky to have been accepted .你很幸运已经被接受了。these criminals are to be hanged .这些罪犯是将被绞死的。we’re glad to have been invited. 受到邀请我们很高兴。what’s to be done next? 下一步做什么？it is an honor for me to be asked to speak here.

song?” “i prefer not to.” “你愿意为他们唱首英文歌吗？”“我不想唱。”you’d better sing an english song if they ask you （to） again.如果他们再要求你，你最好唱一首英文歌。后面常省略不定式而保留to的结构，还有：used to 常常       be going to        打算12345678910111213mean to 打算      ought to          应该plan to  计划      want to          要想两个不定式由and, or, except, but, than 连接时，第二个可省略to，尤其是两个不定式紧密相连时。如：i intend to call on him and discuss this

here.搭出租车也比在这等强。句子中but后面的不定式带不带to，取决于but前面的句子里含不含do，只要有与do/did有关的词（do作谓语，to do作定语等等），but后面的不定式就省掉to。i have no choice but to go there alone. 除了独自一个去以外， 我别无选择。i can do nothing but go there alone. 除了独自一个到那里去，我别无选择。i have nothing to do but go there alone. 除了独自一个到那里去，我没事可干。 he did nothing but cry all day long. 他除了整天哭，什么也不干。 【典型例题】例：用动词的不定式结构完成下列句子：1）let’s _______ （早回家）.→ go home early2）i am going
