一、背景与分值权重

全国联招英语中，非谓语动词约8-12分。单选和完形填空常考不定式、动名词和分词的形式选择，阅读理解中长难句的准确理解也依赖非谓语知识，写作中使用非谓语结构是提升语言层次的重要手段。非谓语动词是连接词法与句法的枢纽，备考价值极高。

二、不定式的句法功能与特殊用法

不定式由to+动词原形构成，在句中可作主语、宾语、表语、定语、状语和补足语。作主语：To see is to believe. 作宾语：I want to go. 作表语：My dream is to become a doctor. 作定语：I have a lot of work to do. 作状语：She came here to learn Chinese——目的状语。作补足语：He asked me to help him.

不定式的特殊用法：不定式作宾语时，若后面还有宾语补足语，常用it作形式宾语而把真正宾语后置——I find it important to learn English well。不定式省略to的结构：感官动词see、watch、notice、hear、feel和使役动词make、let、have后接不定式作宾补时省略to——I saw him enter the room；变被动语态时要补回to——He was seen to enter the room。疑问词+不定式结构：what to do、how to do it、where to go——在句中作主语、宾语或表语——I don't know what to do。不定式的否定式在to前加not——She decided not to give up。

不定式作状语时，目的状语可用in order to或so as to强调——so as to不能放在句首；结果状语常用only to表示出乎意料的结果——He hurried to the station only to find the train had left。too...to和enough...to结构也是高频考点：The box is too heavy to carry；The boy is old enough to go to school。注意不定式作定语与所修饰名词构成动宾关系时，若不定式为不及物动词需加介词——I need a pen to write with。

三、动名词的句法功能与固定搭配

动名词由动词+ing构成，兼具动词和名词特征，在句中可作主语、宾语、表语和定语。作主语：Reading aloud is important. 作宾语：I enjoy reading. 作表语：My hobby is collecting stamps. 作定语：a swimming pool——表用途。动名词作主语时谓语动词用单数；动名词作宾语时要特别注意动词的固定搭配。

只接动名词作宾语的常见动词和短语：admit、avoid、consider、delay、deny、enjoy、finish、imagine、keep、mind、miss、practice、risk、suggest、can't help、give up、put off、feel like、look forward to、be used to、devote to、object to。口诀：考虑建议盼原谅——consider、suggest、look forward to、excuse/pardon；承认推迟没得想——admit、delay/put off、fancy；避免错过继续练——avoid、miss、keep on、practice；否认完成停止吧——deny、finish、stop/give up。

既接不定式又接动名词且意义差别大的动词是重点：remember to do记得去做、remember doing记得做过；forget停止想；regret后悔做过；try to do设法做、try doing试着做；stop to do停下来去做另一件事、stop doing停止正在做的事；go on to do继续做另一件事、go on doing继续做同一件事；mean to do打算做、mean doing意味着做。典型考题：Remember to lock the door when you leave. I remember locking the door yesterday.

四、现在分词与过去分词

现在分词由动词+ing构成，表示主动和进行；过去分词由动词+ed或特殊形式构成，表示被动和完成。分词在句中可作定语、状语、表语和补足语。作定语：a sleeping boy、a broken window；作状语：Hearing the news, they jumped with joy——时间状语；Being tired, I went to bed early——原因状语；作补足语：I saw him crossing the street. I had my car repaired.

现在分词和过去分词的选择关键看与逻辑主语的关系：主动且进行用现在分词，被动且完成用过去分词。The film was interesting——film令人感兴趣；I was interested——我感兴趣。The teacher came in, followed by some students——老师被学生跟着。Choosing the right words is important——主动。The problem being discussed is very difficult——正在被讨论。

分词的时态和语态形式：一般式doing表示主动进行、done表示被动完成；完成式having done表示主动且先于谓语动作发生、having been done表示被动且先于谓语动作发生。Having finished the work, he left the office. Having been told the news, she burst into tears. 现在分词的被动式being done表示正在进行且被动——The bridge being built will be completed next year。

五、非谓语动词的逻辑主语与独立主格

非谓语动词作状语时，逻辑主语必须与句子主语一致；不一致时需使用独立主格结构或用with复合结构。独立主格结构：名词/代词+分词、不定式、形容词、副词或介词短语——The weather being fine, we went for a picnic. 等于Because the weather was fine。He came in, book in hand——相当于with a book in his hand。独立主格在句中作状语，表时间、原因、条件或伴随情况，是写作中的提分结构。

with复合结构：with+宾语+宾补——with the light on、with a book in his hand、with the work done、with him leading the team。with复合结构可作状语表伴随、原因等，也可作定语。典型考题：The teacher entered the classroom, with a book in his hand. With all the work finished, they went home. 注意with后面的宾语与宾补之间的关系：主动用现在分词、被动用过去分词、表示状态用介词短语或副词。

判断逻辑主语的具体方法：先找到非谓语动词所在位置；再看句子的主语是谁；如果非谓语动作是主语发出的用现在分词，是主语承受的用过去分词，如果逻辑主语不是句子主语则需要独立主格或with结构。典型考题：Looking out of the window, I saw the children playing outside——look与I是主谓关系。Looked up at the sky, he saw many stars——此句错误——应该用Looking up at the sky——look与he之间是主动关系。

六、典型综合场景与常见失分点

典型综合场景：完形填空中考查非谓语动词的选择，需要结合上下文逻辑关系：后文表示原因时用分词作状语表原因——Being ill, she didn't go to school；表示结果时用不定式表结果——He woke up to find the fire had gone out；表示目的用不定式——She worked hard to pass the exam。表示伴随用现在分词——He sat there reading a book。解题顺序：先判断非谓语在句中的成分——主语、宾语、定语、状语、补语；再找逻辑主语判断主被动关系；最后结合时间先后选择时态形式。

常见失分点：固定搭配记忆混淆——enjoy后接动名词却写成不定式；使役动词和感官动词后省略to的不定式在被动语态中忘加to；分词作状语时忽略与句子主语的一致性——Expecting/Expected选择错误；动名词逻辑主语用宾格还是所有格拿不准——正式语法中动名词前的逻辑主语用所有格，口语中可用宾格——His coming late made us angry，非正式场合Him coming late也可见到；不定式作定语时漏加介词——a chair to sit容易忽略on；remember/forget/stop/go on等动词后接不定式和动名词的语义差别混淆。

典型错误案例：Seeing from the top of the hill, the city looks beautiful——此句错误——see与city之间是被动关系，应该用Seen from the top of the hill。I am looking forward to hear from you——错误——to在此处是介词，后接动名词hearing。The question is too hard to answer it——错误——too...to结构中不定式的宾语就是前面的主语question，不能再保留it。

训练建议：每天默写只接动名词和不接动名词的动词清单；把remember、forget、regret、try、stop、go on、mean等词的两种搭配对比记忆；做非谓语专项练习时先写一句完整句再划出非谓语结构，标注逻辑主语、成分、主动被动和时态关系；写作时有意识地使用不定式作目的状语、分词作伴随状语和独立主格结构提升语言层次。近五年联招真题中，非谓语动词在单选中占2-3题，完形中约1-2题，写作中使用非谓语结构可获得语言表达加分。
