非谓语动词在高考中的考点及易错点详解

非谓语动词在高考中的考点及易错点详解

非谓语动词在高考中的考点及易错点 一．非谓语题的解题总方法与思路：‎ ‎ 1.先看四个答案：如果四个答案分别为动词原形、不定式、现在分词、过去分词等情况，那么这个题多半是非谓语动词题。‎ ‎ 2.看符号：中间有个逗号，末尾有个句号（有时中间没有逗号）；‎ ‎ 3.看有没有连接词（引导词）。如果用逗号隔开的两个部分都没有连接词的话，一部分是句子时，那么另一部分就一定是非句子，而非句子里的动词就是非谓语动词。‎ ‎ 4.定语态：如果本句的主语（或动词自带的逻辑主语）与它是逻辑上的主谓关系，那么答案一般用Ving形式；如果本句的主语（或动词自带的逻辑主语）与它是逻辑上的动宾关系（被动关系），那么答案一般用Ved形式。‎ ‎ 5.定时态：如果非谓语的动作比谓语先（或先很久）发生，那么非谓语动词要用完成式（to have done/to have been done/ having done/ Having been done），否则我们要用非谓语的一般式（to do / to be done / doing / being done / done）。‎ Eg. ‎ ‎ 1._________ for an hour by his teacher, the boy felt depressed.‎ ‎ A. Being scolded B. Having been scolded C. To be scolded D. Scolding 【1答案：B】‎ 二．非谓语动词可能出现的考查点及易错点：‎ 一)．使用非谓动词的语言结构。‎ ‎1） 在“句子, and/or/but +句子” 的并列句结构中，可能会考查“以动词原形开头”的祈使句，四个答案表面上象非谓语，其实考查的是谓语。‎ ‎ 2.______hard and you will succeed in the exam.‎ ‎ 3.______hard or you will fail in the exam.‎ ‎ A. Study B. To study C. Studying D. Studied 【2、3答案：AA】‎ ‎2） 在“句子，非句子”结构中，非句子部分用非谓语：‎ ‎ 4. The teacher devoted his life to his career, ______ most of his students successful in study.‎ ‎ A. make B. to make C. making D. made 【4答案：C】‎ ‎3） 在“非句子，句子”结构中，非句子部分用非谓语：‎ ‎ 5. _________with children, I know what is needed most.‎ ‎ A. Working B. Having worked C. Worked D. To work 【5答案：B】‎ ‎4) 在“with + 宾语+ 宾语补足语”结构中，宾语补足语可能用非谓语动词：‎ ‎ 6. With her baby _______ on her back, the woman was cleaning the rich man’s house.‎ ‎ A. sleep B. slept C. to sleep D. sleeping 【6答案：D】‎ ‎ 7. With his hair _______ like a role in the film, the boy felt very cool.‎ ‎ A. cut B. to be cut C. cutting D. to cut 【7答案：B】‎ ‎5） 在drive/leave/keep/make/have/let/get/find/hear…等使让动词或感观动词后面作宾语补足语时，也可能用非谓语动词。‎ ‎ 8. He made his sister ______ by taking away her toy.‎ ‎ 9. His sister was made _______ by his taking away her toy.‎ ‎ A. cry B. to cry C. crying D. cried 【8、9答案： A B】‎ ‎ 10. the policeman found the thief ______ his hand into an old man’s pocket and arrested him.‎ ‎ A. put B. putting C. to put D. being put 【10答案：B】‎ ‎ ‎ 二). 非谓语动词考点易错点：‎ ‎1） 表面上考分词，实际上考形容词的情况：‎ ‎ 11.__________ , he fell asleep quickly.‎ ‎ A. Tire B. Tiring C. Tired D. To tire 【11答案：C】‎ ‎ 12.The man won a big prize, __________and ________.‎ ‎ A. surprised ; happy B. surprising ; happy ‎ ‎ C. surprised ; pleasant D. surprising ; pleased 【12答案：A】‎ ‎ 13. _______ in thought of the problems, the man didn’t realize his girlfriend’s coming in.‎ ‎ A. Losing B. Lost C. To lose D. Having lost 【13答案：B】‎ ‎ 14. The students ________ in art can sign in the form and be a member of our school.‎ ‎ A. interest B. interesting C. interested D. To interest 【14答案：C】‎ ‎2) 在“被动形式表主动”情况中出题：‎ ‎ 15. __________ a white skirt, the girl looks like a angel.‎ ‎ A. Worn B. wear C. dressed in D. dressing 【15答案：C】‎ ‎ (wear的后面加衣服；dress表示动作时，后面要加人而不加衣；be dressed in是固定搭配，其中的dressed已经演变成形容词，本是其实可以看成是when the girl is dressed in a white skirt省略而来的。)‎ ‎ 16. _______ in a armchair, he is always surfing online, eating fish and chips.‎ ‎ A. Sit B. Sat C. Seating D. Seated 【16答案：D】 ‎ ‎ （Sit是动词，这里应该用sitting; seat作动词时，其后不加凳子，要加人，而且这个词一般用被动形式表示主动意义。）‎ ‎3） 在“主动形式表被动”的情况中出题：‎ ‎ 17.________ tired and weak, the woman should have a day off to see a doctor.‎ ‎ A. Look B. Looking C. Looked D. Looking 【17答案：D】 ‎ ‎ （look在本题中不是实意动词，而是感观系动词，系动词在非谓语中用主动式表被动。）‎ ‎ 18. With many problems ________ ________ , the newly selected president will have a hard time. ‎ ‎ A. remain; unsettled B. remaining; unsettled ‎ ‎ C. remained ; unsettling D. remained; unsettling 【18答案：B】‎ ‎ （用with开头的部分在这里是一个介词短语，不是句子，因此用非谓语，而remain表示“仍然；仍然是”时是系动词，只能用主动形式；problems与unsettle是动宾关系或被动关系，所以用过去分词unsettled.）‎ ‎ 19. Having some clothes ___________, I cannot join you to see the film.‎ ‎ A. to wash B. to be washed C. washed D . washing 【19答案： A】‎ ‎ （宾语补足语中的动词用非谓语动词；虽然衣服应该是被洗，但是当句子主语与不定式为主谓关系时，我们用主动形式表被动。） ‎ ‎ 20. _________ smooth, this kind of pen sells well in our school.‎ ‎ A. To write B. Writing C. being written D. Written 【20答案 ：B】 ‎ ‎ ｛20解析：动词如果不是表示动作，而是表示物体具有某种性质或特征时，往往用主动形式表示被动。｝‎ ‎4）从“主语一致或主语不一致”角度出题：‎ ‎ 逗号分开的前后两部分有时逻辑主语一致，有时逻辑主语不一致。逻辑主语不一致时，非谓语动词一般要自带逻辑主语，这种现象叫做“分词的独立主格结构。”‎ ‎ 21. _________ from this angle, the mountain looks like a face of a man.‎ ‎ A. To see B. Seeing C. Seen D. Saw 【21答案：C】‎ ‎ ｛21解析：空格处的动词本身没有带主语，那么本句的主语the mountain就要做其逻辑主语，由于the mountain与see是动宾关系，所以我们选用过去分词。｝‎ ‎ 22. _______, I'll go there with you tomorrow afternoon. 【22答案：C】‎ ‎ A. Time permits B. If time permitting C. Time permitting D. Time's permitting ‎ ｛22 解析：permit与I没有主谓关系，也没有动宾关系，permit自带了逻辑主语time(“时间允许的话”)，而time与permit为逻辑上的主谓关系，所以用现在分词的独立结构。｝‎ 注意的几点：‎ 有些分词有时可作分词有时又可作形容词。‎ ‎ 23. _________ enemy, Liu Hunan was very brave. 【23答案C】‎ ‎ 24. _________ with difficulties, we should not give in.【24答案B】‎ ‎ A. To face B. Faced C. Facing D. face ‎ ｛23、24解析：23题中的face是一个动词，由于与Liu Hunan是逻辑上的主谓关系，我们用现在分词形式，；24题中实际上考查了be faced with这一固定搭配，其中的faced看成形容词。｝‎ ‎ 25. The president of South Africa flied to Libya, ______ to help solve the crisis.‎ ‎ 26. The president of South Africa flied to Libya, ______ at helping solve the crisis.‎ A. aim B. aiming C. aimed D. to aim 【25选B 26选C】‎ ‎ ｛25、26解析：25题考查了动词aim to do sth.(旨在做某事)，；26题考查固定搭配be aimed at doing sth. (旨在做某事)其中的aimed看成形容词｝‎ ‎ 27. Though _______ money, his parents sent him to a key university.‎ ‎ 28. Though _______ in money, his parents sent him to a key university.‎ ‎ 29. Though in _____ of money, his parents sent him to a key university.‎ A. lack B. lacking C. lacked D. to lack 【27选B、28选B、29选A】‎ ‎ ｛27、28、29解析：27题中非谓语动词lacking（与his parents及money分别构成逻辑上的主谓关系和动宾关系）；28题中考查了固定搭配：be lacking in(“缺少”)，其中的lacking 为形容词；29题考查了固定搭配（介宾结构）in lack of(“缺少”)，其中的lack是名词，这其实是由though his parents were in lack of money省略了主语和were而业的｝‎ 作结果状语时，doing与(only)to do的区别。‎ ‎ 表示结果状语时，现在分词（v+ing）表示意料之中的结果；而不定式（to do/ only to do）表示意料之外的结果：‎ ‎ 30. His parents were killed in the accident,(thus )_______ him an orphan.‎ ‎ A. leave B. leaving C. left D. to leave 【 30选B】‎ ‎ ｛30解析：他父母出了事故，他变成了孤儿就是意料之中在事情了，用现在分词表结果状语。｝‎ ‎ 31. I hurried to school, only _______ that it was Sunday. 【31选D】‎ ‎ A. find B. finding C. found D. to find ‎ ｛31解析：发现是星期天是我匆忙赶到学校意料之外的结果，说明我忘记了，如果我知道是星期天就不可能还匆忙地赶到学校了。用不定式表意料之外的的结果。｝‎ 作主语时，非谓语动词之to do 与doing 的区别。‎ ‎ 32. _________is a good form of exercise for both young and old. 【32选B】‎ ‎ A. The walk B. Walking C. To walk D. Walk ‎ ｛不定式做主语常表示具体的一次性的动作;动句词表示一般的经常性的动作，多次散步才会有利于健康。｝‎ 演变成了介词或连词的分词。‎ 英语中有些词表面上看是分词，但实际上已经变成了介词，因此应该用ing形式还是分词ed形式已经变得约定俗成了。这时往往不适用非谓动词规则，而是看英美人士的习惯。‎ ‎33. ___________her age，she looks quite young．‎ A．Consider B. Considered C. To consider D. Considering ‎｛33解析：题意是：“就她的年龄而论，她显得十分年轻。”这里的considering表示“考虑到；鉴于”，它已经变成了介词，不管是“考虑还是被考虑”这里都用considering。｝‎ 高中阶段我们还学过的有：‎ 介词 concerning regarding according to including owing to 关于 关于 根据；按照 包括 因为；由于 连词 given supposing seeing (that) imaging providing/provided 鉴于 假如 因为；既然 假如 假如 有些非谓语动词是省略而来的，有些则不是。‎ ‎34. ______ by her mother, the girl burst into tears. 【34选B】‎ A. Be scolded B. Scolded C. Scolding D. To scold ‎｛34解析：scold与the girl是动宾关系，因此用过去分词作原因状语；其实这个句子也是由一个完整的原因状语从句省略来的。原句为：Because the girl was scolded by her mother, the girl burst into tears.当主从复合句的主语一致，且谓语动词里有be 动词时，可以把 “连词+主语+be” 部分省略。｝‎ ‎35. ____________ the tomb for 5 years, he is now called an expert more or less. 【35选B】‎ A. Studying B. Having studied C. Having been studied D. To study ‎｛35解析：逗号前面部分不是句子省略而来，由于he 与study是逻辑上的主谓关系，加上study在先（有5年了），被 叫做“专家”在后，所以用非谓语动词的主动完成式｝‎ ‎“连词+分词”和“介词+动名词”的区别。‎ ‎36. if _________ another hour, I would have finished it better.(give的恰当形式填空)。‎ ‎37. While _________ homework, the boy likes listening to light music.(do的恰当形式填空)‎ ‎｛6、37解析：36.given 是由if I had been given another hour省略来的，if 在省略前省略后都是连词；37.doing 是由while the boy are doing homework省略来的，while在省略前后都是连词｝‎ ‎38. After __________ , he found a job as a secretary in a company.(graduate的恰当形式填空)‎ ‎39. Before_________ a proper person to be the new president, the old president wouldn’t resign.(select的恰当形式填空)‎ ‎｛38、39解析：38. graduating/graduation after 这时是个介词，所以后面总是用动名词，如果改为after he graduated，那么这个after就变成了连词。39题中的before用法与after 一样，后面加句子时，是连词，后面只加一个动词时，要用动名词形式，并充当介词。所以39填selecting｝‎ 非谓语动词专练：‎ ‎1.
