高中英语知识点归纳非谓语动词作主语
高中英语知识点归纳非谓语动词作主语非谓语动词作主语是高中英语中的重要知识点之一。
它不仅在语法上起着重要作用，而且在写作和阅读中也具有广泛的应用。
本文将对非谓语动词作主语进行归纳总结，以帮助同学们更好地掌握和运用这一知识点。
一、非谓语动词作主语的定义非谓语动词指的是动词的非限定形式，包括不定式、动名词和分词。
当不定式、动名词或分词短语作为句子的主语时，就称之为非谓语动词作主语。
例如：1. 不定式作主语：To travel around the world is my dream.（环游世界是我的梦想。
）2. 动名词作主语：Swimming is good for your health.（游泳对健康有益。
）3. 分词作主语：Walking in the park is a popular activity.（在公园散步是一项受欢迎的活动。
）二、非谓语动词作主语的用法1. 非谓语动词作主语可以表示一种普遍的、抽象的概念或真理。
例如：To love is to care for others.（爱就是关心他人。
）2. 非谓语动词作主语可以表示一种具体的、个人的愿望或目标。
例如：My dream is to become a doctor.（我的梦想是成为一名医生。
）3. 非谓语动词作主语可以表示一种习惯、常态或现象。
例如：Playing basketball in the evening is their daily routine.（他们每天晚上打篮球是他们的日常活动。
）4. 非谓语动词作主语还可以与一些特定的动词搭配，构成固定的表达方式。
例如：What I miss most is eating my mom’s homemade foo d.（我最怀念的是吃我妈妈做的家常菜。
）三、非谓语动词作主语的注意事项1. 非谓语动词作主语时，谓语动词要用单数形式。
例如：To speak English well is important for your career.（说好英语对你的事业很重要。
不定式做主语谓语的单复数
不定式作主语时谓语动词的单复数选择一、什么是不定式不定式是一种非谓语动词，它由to和动词原形构成，如to do, to see, to write等。
不定式可以在句子中充当主语、宾语、补语、定语、状语等成分，具有一定的动词性和名词性。
不定式可以有主动式和被动式两种形式，主动式表示主动的意义，被动式表示被动的意义。
不定式的被动式由to be和过去分词构成，如to be done, to be seen, to be written等。
不定式的被动式只能用于及物动词，如果是不及物动词，要在后面加上合适的介词，如to be laughed at, to be looked for 等。
二、不定式作主语时，谓语动词的单复数形式的选择原则1. 一般原则不定式作主语时，谓语动词一般用单数，因为不定式相当于一个抽象的名词，表示一个动作或状态的概念，而不是一个具体的人或物。
例如：To learn a foreign language well is not easy. 学好一门外语不容易。
但是，有时也可以用复数，主要取决于不定式的意义和语境。
如果不定式表示一个具体的、个别的或多个的动作或状态，谓语动词可以用复数。
例如：To see and to hear are two different things. 看和听是两回事。
2. 形式主语不定式作主语时，常用it作形式主语，将不定式放在句子后面，以避免头重脚轻的现象。
这时，谓语动词要与形式主语it 保持一致，用单数。
例如：It is important to protect the environment. 保护环境是重要的。
It is a pleasure to meet you. 见到你很高兴。
3. 形容词修饰不定式作主语时，如果不定式前有形容词修饰，谓语动词要与形容词保持一致，即如果形容词是单数，谓语动词也用单数；如果形容词是复数，谓语动词也用复数。
例如：One thing to remember is that you are not alone. 要记住的一件事是，你不是孤独的。
不定式的六种用法
不定式的六种用法1、不定式作主语例如：To remember this is very important.注意：为了避免头重脚轻，在许多情况下，通常都将作主语的不定式置于句子后部，而在句首主语位置使用形式主语it。
例如：It is very important to remember this.2、不定式作表语例如：He seems to be ill.注意：不定式作表语主要有三种情况，一是用于seem, appear, prove 等系动词之后的不定式（尤其是to be），二是像My job is to sweep the floor. 这样的主语与表语“等价”的情形，三是表示想法、约定、义务、命令、可能性、命运等，如：You are to come when I call.3、不定式作宾语例如：I can not afford to buy a car.注意：①不定式不仅用作动词的宾语，还可用作个别介词（but, except）的宾语。
例如：I had no choice but to wait.②当作宾语的不定式后跟有宾语补足语时，通常要用形式宾语it代替不定式，并将真正的宾语不定式置于宾语补足语之后例如：I find it difficult to learn Japanese well.4、不定式作宾语补足语例如：Who taught you to drive?5、不定式作定语例如：I have a question to ask you.注意：有的名词（如way, chance, right等）后用作不定式可换成of doing sth.如：It is the best way to do (of doing) it.但是以下名词后接不定式作定语时通常不能换成of doing sth. attempt courage decision effort fortune failure invitation wish6、不定式作状语例如：I went to France to learn French.。

2.不定式作宾语:①有些动词能直接带不定式，而不能直接带动名词，这类动词有agree, aim, apply,arrange, choose, claim, decide, demand, desire, determine,, expect, hope, learn, manage, offer, prepare, pretend, promise, refuse, seek, swear, threaten, undertake, venture, volunteer,等②动词不定式也可作介词宾语，动词不定式也可与wh-疑问词连用，如He gave me some advice on how to learn English.介词except, but后，如果之前有动词do及其变形(do的某种形式)，则其后跟不带to不定式，否则不定式带to，如They did nothing except work. ⇔ There’s no choice but to wait.形象描述为“有毒(do及其变形)无兔(to)，有兔(to)无毒(do及其变形)”(有毒则无兔子)3.不定式作宾语补足语:①有一些动词必须先带宾语再带不定式(且必须为带to不定式)，而不能直接带不定式，这类动词包括[1]arrange for, ask for, rely on, call on, wait for等词组动词；[2]consider, declare, find, prove, think, believe, discover, feel, judge, suppose, understand, want, wish, expect等表示心理状态的动词；[3]advise, allow, forbid, permit, recommend, require, urge, ask, tell, order, beg, help, persuade, prepare, cause, force, invite, oblige, enable, get, encourage, remind, request, command, warn, drive等表示劝告、允许、禁止等动词；使役动词、感官动词一般后跟不带to不定式，注意改为被动语态时需恢复to②第[2]类动词中，其后的不定式总带to，通常为to be，往往可以省略，如We considered him (to be) foolish.③第[3]类动词中advise, allow, forbid, permit, recommend等动词也可直接跟动名词作宾语，如She advised giving up smoking. ⇒ She advised us to give up smoking.④let, make, have等使役动词+宾语，之后用不带to不定式，当使役动词为被动态时，则需将不带to不定式转为带to不定式see, hear, observe, notice, feel, watch, look at, listen to等感官动词+宾语，之后用不带to不定式，当上述动词为被动态时，则需将不带to不定式转为带to不定式help或help +宾语后既可用带to不定式，也可以不带to不定式。
非谓语动词(不定式)的用法
非谓语动词(不定式)的用法非谓语动词（动词不定式的具体用法）动词不定式有三大语法功能：1.充当名词，可作主语、宾语或表语；2.充当形容词，可作后置定语或宾语补足语；3.充当副词，可作状语。

例如：___.（赢得冠军是我的雄心。
）To master a foreign language is necessary.（掌握一门外语是有必要的。

动词不定式作主语的用法教案
动词不定式作主语的用法教案动词不定式作主语的用法在英语中非常常见，尤其是在正式的语言场合中。
这种用法在语法上称为“不定式作主语”。
不定式作主语的用法是指将一个动词不定式作为一个完整的句子的主语。
在这篇文章中，我们将详细探讨不定式作主语的用法及其相关的句式结构和语法规则。
Part 1: 什么是不定式作主语不定式是一种特殊的动词形式，由“to”+动词原形构成。
它可以使用作为名词、形容词或副词。
在不定式中，动词前面的“to”是不确定的助动词，并且不参与表达时态和语态，而是用于将动词转换为名词、形容词和副词等语言形式。
不定式作主语是将不定式用作句子的主语。
这种用法是非常常见的，在语法上与其他名词性短语作主语的用法非常相似。
由于不定式作主语不是一个完整的句子，所以通常需要在不定式前面添加一个“it is”的子句或者其他的类似结构。
以下是一些例句，它们展示了不定式作主语的用法：To visit Japan is my dream.To learn English well requires practice.To be rich is not easy.这些句子中的不定式均被用于表示一种具体的含义，这正是不定式作主语的用法的主要作用。
Part 2: 不定式作主语的句式结构一般来说，不定式作主语的句式结构是“it+be+不定式原型”或“不定式原型+be”。
例如：It is important to study hard.To know you is to love you.To live happily is everyone's dream.这些句子的基本结构都是“it+be+不定式原型”，这已经成为了不定式作主语的一种固定句式。
不过，有时也可以将不定式放在句子的开头，如：To tell you the truth, I don't like him.To succeed in life, you must work hard.To be or not to be, that is the question.在这些句子中，不定式出现在主语之前，但仍可以作为句子的主语。

9. Last summer I took a course on ________ .
A. how to make dresses
B. how dresses be made
C. how to be made dresses
3. "疑问代词、疑问副词 + 不定式"常常用作动词或介词的宾语。例如：
I don't know where to spend my holiday. 我不知该去哪儿度假。
Have you decided when to marry?你决定什么时候结婚了吗？
[高考题例]
3. She pretended ________ me when I passed by.
当表语形容词说明不定式的逻辑主语具有某种品质时,常用"It's...of sb. to do sth."。例如：
It's very kind / nice of you to help me。感谢你的帮助。
当表语形容词说明不定式具有某种特征时，应使用 "It's ...for sb. to do sth."。例如：
[高考题例]
12. Tom kept quiet about the accident ________ lose his job.

如：Fen asked her mother to give her twenty dollars.（而不用Fen asked her mother giving her twenty dollars.）（2）动词不能接动名词作主语可以用不定式来替代，表示让、叫、让、觉得、告诉、是否等概念时。
如：Choose a book you like to read.（而不用Choose a book reading.）二、动名词作主语动名词作主语表示动作的主体，构成主谓结构，动名词后面往往要加上表示动作的宾语及及其他补足语。
