非谓语动词是英语语法里的高分重点,也是写作中**瞬间提升句子档次**的核心工具。不管是考试单选、语法填空、短文改错,还是作文升级,掌握非谓语动词,就能少丢分、多拿分。
很多同学觉得它难,其实只要分清to do / doing / done三种形式的功能,就能彻底搞定。下面用最清晰、最实用的方式讲透。

一、什么是非谓语动词?一句话看懂
一个句子里已经有谓语动词了,再出现的动词就不能作谓语,必须变成非谓语形式。
非谓语只有三种:to do 不定式、doing 动名词/现在分词、done 过去分词。
二、三种非谓语核心用法(最清晰对比)
1. to do 不定式
含义:表目的、将来、要去做的动作。
常用功能:作目的状语、后置定语、宾语。
例句:I got up early to catch the bus.(表目的)
例句:I have a lot of work to do.(作定语)
2. doing 动名词 / 现在分词
含义:表主动、进行、习惯、抽象动作。
常用功能:作主语、宾语、状语、定语。
例句:Reading is useful.(作主语)
例句:He kept studying all day.(作宾语)
3. done 过去分词
含义:表被动、完成、状态。
常用功能:作定语、状语、补语。
例句:The book written by Mo Yan is popular.(被动)
例句:Seen from the top, the park looks beautiful.(被动完成)
三、写作高分必用:非谓语高级替换技巧
1. to do 替换目的状语从句(立刻简洁)
普通句:I study hard so that I can get good grades.
高级句:I study hard **to get** good grades.
2. doing 替换原因/时间状语从句
普通句:Because I was tired, I rested for a while.
高级句:Being tired, I rested for a while.
3. done 替换定语从句(瞬间高级)
普通句:The boy who is standing there is my brother.
高级句:The boy standing there is my brother.
4. with 复合结构(作文加分亮点)
例句:He fell asleep with the light on
例句:She left the room with the door closed
四、考试必考:易混点彻底分清
1. remember / forget / regret
to do:还没做(记得/忘记/后悔要做)
doing:已经做了(记得/忘记/后悔做过)
例:I forgot to bring my wallet.(忘记带)
例:I forgot telling him.(忘了告诉过他)
2. stop / try
stop to do:停下来去做另一件事
stop doing:停止正在做的事
3. 只能接 doing 的动词(必背)
enjoy, mind, avoid, finish, practice, keep, suggest, miss, be worth
例:She enjoys drawing
五、最容易丢分的陷阱:逻辑主语一致
分词作状语时,动作的发出者必须和主句主语一致。
❌ 错误:Looking out of the window, the birds are flying.
✅ 正确:Looking out of the window, I saw the birds flying.
六、写作实战升级(直接套用)
基础句:When I finished my homework, I went out to play.
升级句:Having finished my homework, I went out to play.
基础句:If time permits, we will go for a walk.
升级句:Time permitting, we will go for a walk.(独立主格)
七、快速记忆口诀
目的将来用 to do,主动进行用 doing,被动完成用 done。
主语宾语常用 doing,定语状语三种都可。
逻辑主语要一致,写作升级最给力!
