一、背景與分值權重

全國聯招英語中，非謂語動詞約8-12分。單選和完形填空常考不定式、動名詞和分詞的形式選擇，閱讀理解中長難句的準確理解也依賴非謂語知識，寫作中使用非謂語結構是提升語言層次的重要手段。非謂語動詞是連接詞法與句法的樞紐，備考價值極高。

二、不定式的句法功能與特殊用法

不定式由to+動詞原形構成，在句中可作主語、賓語、表語、定語、狀語和補足語。作主語：To see is to believe. 作賓語：I want to go. 作表語：My dream is to become a doctor. 作定語：I have a lot of work to do. 作狀語：She came here to learn Chinese——目的狀語。作補足語：He asked me to help him.

不定式的特殊用法：不定式作賓語時，若後面還有賓語補足語，常用it作形式賓語而把真正賓語後置——I find it important to learn English well。不定式省略to的結構：感官動詞see、watch、notice、hear、feel和使役動詞make、let、have後接不定式作賓補時省略to——I saw him enter the room；變被動語態時要補回to——He was seen to enter the room。疑問詞+不定式結構：what to do、how to do it、where to go——在句中作主語、賓語或表語——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。

不定式作狀語時，目的狀語可用in order to或so as to強調——so as to不能放在句首；結果狀語常用only to表示出乎意料的結果——He hurried to the station only to find the train had left。too...to和enough...to結構也是高頻考點：The box is too heavy to carry；The boy is old enough to go to school。注意不定式作定語與所修飾名詞構成動賓關係時，若不定式爲不及物動詞需加介詞——I need a pen to write with。

三、動名詞的句法功能與固定搭配

動名詞由動詞+ing構成，兼具動詞和名詞特徵，在句中可作主語、賓語、表語和定語。作主語：Reading aloud is important. 作賓語：I enjoy reading. 作表語：My hobby is collecting stamps. 作定語：a swimming pool——表用途。動名詞作主語時謂語動詞用單數；動名詞作賓語時要特別注意動詞的固定搭配。

只接動名詞作賓語的常見動詞和短語：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。口訣：考慮建議盼原諒——consider、suggest、look forward to、excuse/pardon；承認推遲沒得想——admit、delay/put off、fancy；避免錯過繼續練——avoid、miss、keep on、practice；否認完成停止吧——deny、finish、stop/give up。

既接不定式又接動名詞且意義差別大的動詞是重點：remember to do記得去做、remember doing記得做過；forget停止想；regret後悔做過；try to do設法做、try doing試着做；stop to do停下來去做另一件事、stop doing停止正在做的事；go on to do繼續做另一件事、go on doing繼續做同一件事；mean to do打算做、mean doing意味着做。典型考題：Remember to lock the door when you leave. I remember locking the door yesterday.

四、現在分詞與過去分詞

現在分詞由動詞+ing構成，表示主動和進行；過去分詞由動詞+ed或特殊形式構成，表示被動和完成。分詞在句中可作定語、狀語、表語和補足語。作定語：a sleeping boy、a broken window；作狀語：Hearing the news, they jumped with joy——時間狀語；Being tired, I went to bed early——原因狀語；作補足語：I saw him crossing the street. I had my car repaired.

現在分詞和過去分詞的選擇關鍵看與邏輯主語的關係：主動且進行用現在分詞，被動且完成用過去分詞。The film was interesting——film令人感興趣；I was interested——我感興趣。The teacher came in, followed by some students——老師被學生跟着。Choosing the right words is important——主動。The problem being discussed is very difficult——正在被討論。

分詞的時態和語態形式：一般式doing表示主動進行、done表示被動完成；完成式having done表示主動且先於謂語動作發生、having been done表示被動且先於謂語動作發生。Having finished the work, he left the office. Having been told the news, she burst into tears. 現在分詞的被動式being done表示正在進行且被動——The bridge being built will be completed next year。

五、非謂語動詞的邏輯主語與獨立主格

非謂語動詞作狀語時，邏輯主語必須與句子主語一致；不一致時需使用獨立主格結構或用with複合結構。獨立主格結構：名詞/代詞+分詞、不定式、形容詞、副詞或介詞短語——The weather being fine, we went for a picnic. 等於Because the weather was fine。He came in, book in hand——相當於with a book in his hand。獨立主格在句中作狀語，表時間、原因、條件或伴隨情況，是寫作中的提分結構。

with複合結構：with+賓語+賓補——with the light on、with a book in his hand、with the work done、with him leading the team。with複合結構可作狀語表伴隨、原因等，也可作定語。典型考題：The teacher entered the classroom, with a book in his hand. With all the work finished, they went home. 注意with後面的賓語與賓補之間的關係：主動用現在分詞、被動用過去分詞、表示狀態用介詞短語或副詞。

判斷邏輯主語的具體方法：先找到非謂語動詞所在位置；再看句子的主語是誰；如果非謂語動作是主語發出的用現在分詞，是主語承受的用過去分詞，如果邏輯主語不是句子主語則需要獨立主格或with結構。典型考題：Looking out of the window, I saw the children playing outside——look與I是主謂關係。Looked up at the sky, he saw many stars——此句錯誤——應該用Looking up at the sky——look與he之間是主動關係。

六、典型綜合場景與常見失分點

典型綜合場景：完形填空中考查非謂語動詞的選擇，需要結合上下文邏輯關係：後文表示原因時用分詞作狀語表原因——Being ill, she didn't go to school；表示結果時用不定式表結果——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。表示伴隨用現在分詞——He sat there reading a book。解題順序：先判斷非謂語在句中的成分——主語、賓語、定語、狀語、補語；再找邏輯主語判斷主被動關係；最後結合時間先後選擇時態形式。

常見失分點：固定搭配記憶混淆——enjoy後接動名詞卻寫成不定式；使役動詞和感官動詞後省略to的不定式在被動語態中忘加to；分詞作狀語時忽略與句子主語的一致性——Expecting/Expected選擇錯誤；動名詞邏輯主語用賓格還是所有格拿不準——正式語法中動名詞前的邏輯主語用所有格，口語中可用賓格——His coming late made us angry，非正式場合Him coming late也可見到；不定式作定語時漏加介詞——a chair to sit容易忽略on；remember/forget/stop/go on等動詞後接不定式和動名詞的語義差別混淆。

典型錯誤案例：Seeing from the top of the hill, the city looks beautiful——此句錯誤——see與city之間是被動關係，應該用Seen from the top of the hill。I am looking forward to hear from you——錯誤——to在此處是介詞，後接動名詞hearing。The question is too hard to answer it——錯誤——too...to結構中不定式的賓語就是前面的主語question，不能再保留it。

訓練建議：每天默寫只接動名詞和不接動名詞的動詞清單；把remember、forget、regret、try、stop、go on、mean等詞的兩種搭配對比記憶；做非謂語專項練習時先寫一句完整句再劃出非謂語結構，標註邏輯主語、成分、主動被動和時態關係；寫作時有意識地使用不定式作目的狀語、分詞作伴隨狀語和獨立主格結構提升語言層次。近五年聯招真題中，非謂語動詞在單選中佔2-3題，完形中約1-2題，寫作中使用非謂語結構可獲得語言表達加分。
