四、语法点
本单元主要语法是 动词不定式(不定式做宾补和状语),这里有拓展,整体进行不定式用法的一个汇总。
一)概念
动词不定式是一种非谓语动词形式,意味着它不能在句子中独立作谓语。它由 to + 动词原形 构成,但有时可以省略 to。
它在句中起名词、形容词或副词的作用,同时保留动词的某些特性(可以带自己的宾语、状语等)。
2. 基本形式:
带 to 的不定式如:to do, to be, to have, to play, to study
不带 to 的不定式(裸不定式):在特定动词和结构后,to 必须省略。
二) 句法功能(在句子中充当的成分)
动词不定式几乎可以充当除谓语以外的所有成分。
1. 作主语 (Subject)
用法:表示某个动作或状态。
位置:
直接置于句首(常用于陈述句,有时显得头重脚轻):
To learn a new language is challenging. 学习一门新语言是具有挑战性的。
To err is human. 犯错乃人之常情。
更常用的形式:用 It 作形式主语,将真正的主语(不定式)后置,使句子平衡。
It is challenging to learn a new language.
It is important to get enough sleep. 获得足够的睡眠很重要。
It took me an hour to finish the work. 完成这项工作花了我一个小时。
2. 作宾语 (Object)
用法:紧跟在及物动词之后,表示动作的内容。
常用后接不定式作宾语的动词:
want (想要), hope (希望), wish (希望)
plan (计划), decide (决定), choose (选择)
agree (同意), promise (承诺), refuse (拒绝)
learn (学习), manage (设法完成), fail (未能)
offer (提供), ask (要求), help (帮助) - help 后接不定式可带 to 也可不带。
例句:
She wants to become a doctor. 她想成为一名医生。
They decided to move to another city. 他们决定搬到另一个城市。
He promised to be here on time. 他承诺会准时到这里。
We are learning to code. 我们正在学习编程。
3. 作宾语补足语 (Object Complement)(本单元涉及的主要部分)
用法:对宾语进行补充说明,表示宾语“做什么”或“是什么状态”。
结构:主语 + 谓语动词 + 宾语 + (to) do sth.
情况一:带 to 的不定式
常用动词:ask (要求), tell (告诉), want (想要), invite (邀请), encourage (鼓励), allow (允许), order (命令), warn (警告), would like (想要)。
例句:
The teacher asked us to be quiet. 老师要求我们保持安静。
My parents want me to study hard. 我父母想让我努力学习。
I invited him to join our party. 我邀请他参加我们的聚会。
情况二:不带 to 的不定式(裸不定式)
常用动词:let (让), make (使), have (让,使) - 这些是"使役动词"。以及感官动词 see, watch, hear, feel, notice (注意到) 等。
例句:
Let me help you. 让我来帮你。
The movie made me cry. 那部电影让我哭了。
I saw him enter the building. 我看见他进了大楼。
I heard her sing in the next room. 我听到她在隔壁唱歌。
【重要提示】 在被动语态中,这些动词后面的不定式必须恢复 to。
He was made to clean the room. (被动) 他被要求打扫房间。
She was seen to leave. (被动) 有人看见她离开了。
4. 作表语 (Predicative)
用法:放在系动词(如 be, seem, appear 等)之后,说明主语的内容。
例句:
My dream is to travel around the world. 我的梦想是环游世界。
His wish is to be a pilot. 他的愿望是当一名飞行员。
She seems to be tired. 她似乎累了。
5. 作定语 (Attribute)
用法:放在名词或代词后面,修饰这个名词,表示一个未来的动作。
常见被修饰词:
way (方法), time (时间), chance (机会), opportunity (机会), reason (理由), something, anything, nothing 等。
例句:
I have a lot of homework to do. 我有很多作业要做。
She is the right person to talk to. 她是可以交谈的合适人选。
There is nothing to worry about. 没什么可担心的。
This is the best way to solve the problem. 这是解决这个问题的最好方法。
6. 作状语 (Adverbial)(本单元主要涉及的部分)
用法:修饰动词、形容词或整个句子,表示目的、结果、原因等。
(1)目的状语 (最常见):为了做某事,可以放在句首或句尾。为了强调目的,可以用 in order to 或 so as to。
He came to help me. 他来是为了帮我。

(3)原因状语:说明产生某种情绪的原因。

三) 特殊形式与结构
1. 疑问词 + 动词不定式
结构:what/which/when/where/how/whether + to do
功能:相当于一个名词短语,常在句中作主语、宾语、表语等。
常用动词:know, decide, tell, show, learn, forget, remember, wonder。
例句:

The question is where to find the money. (作表语) 问题是去哪里找这笔钱。
When to start has not been decided. (作主语) 何时开始还没有决定。
2. 不定式的否定形式
结构:not (或 never) + to do

例句:
He told me not to be late. 他告诉我不要迟到。
It's impolite not to say "Thank you". 不说"谢谢"是不礼貌的。
She decided never to see him again. 她决定再也不见他。
3. 不定式的时态和语态
虽然不定式不能单独作谓语,但它本身有简单的时态和语态变化。
下面作为了解。
形式 构成 含义与用法 例句
一般式 to do 动作与谓语动词同时发生或在其后发生 I want to play football. (想和玩同时或之后)
进行式 to be doing 强调动作在谓语动词发生时正在进行 He seems to be sleeping. (似乎正在睡觉)
完成式 to have done 动作在谓语动词发生之前已经完成 I'm sorry to have troubled you. (麻烦已经发生)
被动式 to be done 逻辑主语是不定式动作的承受者 The house needs to be cleaned. (房子需要被打扫)
完成被动式 to have been done 被动动作在谓语动词之前已完成 The book is said to have been translated. (书据信已被翻译)
