1、,非谓语动词是语法填空的必考考点,每年高考至少有1道题。不仅如此,掌握非谓语动词的基本用法,对增强书面表达的文采和提高阅读理解能力都有明显的作用。首先,我们回顾一下非谓语动词的语法功能(在句中充当何种成分):,考点解密,现在,我们简要回顾其主要考点:,考点1:作主语表示一般的、泛指的或习惯性的行为用-ing形式;表示具体的、一次性的或将来的动作用不定式。考点2:作表语(1) 动名词和不定式作表语说明主语的具体内容。(2)分词作表语则说明主语的性质,像puzzling, surprising, exciting等-ing分词表示“令人的(事物)”;像puzzled, surprised, exc
2、ited等-ed分词表示“(人)感到的”。,考点3:作宾语(1)有些动词只能用不定式作宾语。如refuse, expect, promise, decide, offer, pretend等。(类似动词和短语动词还有哪些?请补上)(2)有些动词只能用动名词作宾语。如:keep, allow, finish, enjoy, mind, practice, avoid, admit, advise, consider, imagine, appreciate, escape, suggest等。(类似动词和短语动词还有哪些?请补上)(3) 在表示“需要”的need, want和require等后用
3、-ing形式的主动形式表示被动意义,也可用不定式的被动式。,(4)在forget, remember, regret, mean, try等动词后既可接动名词,也可接不定式,但意义差别较大。(5)在介词之后用动名词作宾语。注意to是介词的短语,如be /get used to, be accustomed to(习惯于), contribute to , devote oneself to /be devoted to, get down to, look forward to等。(6)含介词的固定句式:prevent /stop /keep sb. /sth. from doing 阻止做,
4、spend /waste time or money in doing 在做方面花费/浪费时间或金钱have some difficulty/trouble in doing 在做方面有些困难have a hard time in doing sth.做某事很艰难there is no sense in doing做是没有理由/道理的(7)介词后一般只能接动名词,但在表示“除外”的介词but和except后,有时可接不定式;当前面有行为动词do时,不定式不带to;前面没有行为动词do时,要带to。,考点4:作宾补当宾语与作宾补的动词在逻辑上是主动关系时,用不定式(未来或全过程)或-ing形式(
5、正在进行或一直处于某种状态);当宾语与作宾补的动词在逻辑上是被动关系时,用-ed形式。另外,请注意复习以下6点:(1)在ask, invite, encourage, advise, forbid, remind等动词后,用带to的不定式作宾补。(2)在help后作宾补的不定式带不带to均可。,(3)在make, let, have等使役动词和feel, smell, hear, see, watch等感官动词后,一般用不带to的不定式作宾补,但在其被动式后作主语补足语时,要加上to。(4)在with的宾语后,若用-ed形式,表示宾语与-ed形式在逻辑上是被动关系,且意味着该动作已经完成;若用
6、-ing形式,表示宾语与-ing形式在逻辑上是主动关系,且表示动作持续进行。,(5)get sb. to do sth. =have sb. do sth.使某人做某事(主动、将来); get/havedoing使处于某一状态中(主动、持续); getdone=have sth. done请人做/遭受(被动)。(6) make oneself 后常用understood, heard, seen, known等作宾补,表示让别人明白自己的意思/让自己讲的话被别人听到/让自己被别人看到/让自己被别人认识。,考点5:作状语(1)在表示时间、让步、方式或伴随情况时,非谓语动词若与句子主语在逻辑上是主
7、动关系,用-ing形式,若与句子主语在逻辑上是被动关系,用-ed形式。(2)不定式作状语只能放在句末,且不用逗号,多用于表示情绪或情感反应的动词、形容词(如glad, sorry, surprised, frightened, delighted)之后,表示原因。(3)不定式表结果,其动作发生在谓语动词之后,往往表示未曾预料到的或令人不快的,前面常加only;也还用于tooto, enough to, so/suchas to等固定结构中。-ing形式表示的结果,是伴随谓语动词的发生而产生的自然结果(同时发生),谓语动词与现在分词的动作是因果关系。,(4)在作表语的形容词后或者作宾补的形容词后
8、作状语,一般只用不定式。(5)表示目的时只能用不定式,此时的不定式可以放在句首。(6) 在“连词(如when, while, if, though等)+分词”结构中,当分词与主句主语是主动关系时用-ing形式,是被动关系时用-ed形式。,考点6:作定语(1)动词不定式作定语:常放在所修饰的名词之后,表示一个将来的动作,多用来修饰have、there be、with之后的名词,表示“有要”;或修饰“the+序数词”。(2)分词作定语:被修饰的名词与分词是主动关系,用-ing形式,是被动关系时用-ed形式。,考点7:特殊句式Why not do sth.? =Why dont you do sth
9、.?何不做某事呢?had better (not) do sth.最好(不)做某事would rather (not) do sth.宁愿(不)做某事would do A rather than do B = would rather do A than do B = prefer to do A rather than do B = prefer doing A to doing B 宁做A事不做B事,考点8:独立结构(1) -ing形式的独立成分:judging by /from(根据判断), generally speaking(一般说来),strictly speaking(严格说来)
10、, frankly speaking(坦率地说)等。(2)不定式的独立结构:to tell you the truth(和你说实话吧), to make things worse(情况更糟的是)等。(3)用作介词或连词的considering(考虑到,就而言)和given(考虑到)后接名词或that从句。,解答语法填空时,首先分析句子结构,若句子已有谓语动词且不是并谓语时,所给动词必定用非谓语动词;然后分析该非谓语动词在句中作什么句子成分,初定作该成分的应是哪一种或几种非谓语动词形式;最后再根据非谓语动词各自的特点和用法,同时看谓语动词有没有特别的要求,再结合与逻辑主语的关系,确定该填哪种形式
11、。,解题技巧,另外,在确定用-ing形式还是用-ed形式,用to do还是用to be done时,都是由该非谓语动词与逻辑主语是主动关系还是被动关系来确定的。那么,如何找出非谓语动词的逻辑主语?这与非谓语动词在句中作何种成分有关,详见下表:,例1the proverb, “plucking up a crop 32 (help) it grow”, is based on the following story. (2008年广东),实例剖析,思路分析:因句中已有谓语is based,而“plucking up a crop 32 (help) it grow”是the proverb的同位
12、语,是一个名词短语而非同位语从句,因此,help应是谓语动词;“帮助禾苗长”是“将禾苗拨起来”的目的,作目的状语,用动词不定式,故填to help。,例2While she was getting me _34_ (settle) into a tiny but clean room(2007年广东),思路分析:因句中已有谓语was getting,所以settle应是非谓语动词;又由settle sb. into/in/on(使某人舒服地处于某处)可知,me与settle是被动关系,要用过去分词用宾补,故填settled。,非谓语动词,一、考点分析非谓语动词在语法填空中,每年必考,且每年一个
13、小题,但四年来,只涉及到非谓语动词的两种用法。,1.作状语。(2010年广东)He spit it out, 37 (say) it was awful. 解析因句中已有谓语spit,此处又没有连词,say不是并列谓语,而是非谓语动词;又因he与say是主动关系,故用现在分词作伴随状语。,saying,2.作宾补。(2007年广东)Finally, I accepted the offer of an old peasant woman who lived alone in a little house. While she was getting me 34 (settle) into a
14、tiny but clean room,解析由settle sb. into/in/on(使某人舒服地处于某处)可知,me与settle是被动关系,要用过去分词用宾补。又如:A nurse settled the old man into a chair.护士让那位老人舒舒服服地坐在椅子上。,settled,温馨提示:虽然只考查了非谓语动词作状语和作宾语补足语,但复习时,非谓语动词作定语、作主语和作宾语也不可忽视。,二、真题演练用所给词的适当形式填空。1. She wished that he was as easy 32 (please) as her mother, who was alw
15、ays delighted with perfume. (2009年广东),1. to please 句中已有谓语was easy,please应为非谓语动词;因在形容词后作状语,只能用动词不定式,故填to please。,to please,2. For example, the proverb, “plucking up a crop32 (help) it grow”, is based on the following story. (2008年广东),2. to help 作目的状语,用动词不定式。,to help,3. There were many talented actors
16、 out there just waiting _ (discover). (2010江西卷),3. to be discovered。动词wait后习惯上接不定式;另外,actors与discover之间为被动关系,即“等着被发现”,故选不定式的被动式。,to be discovered,4. We were astonished _(find) the temple still in its original condition. (2010辽宁卷),4. to find。be astonished后要接不定式表示原因。,to find,5. With Fathers Day around
17、 the corner, I have taken some money out of the bank _ (buy) presents for my dad. (2010全国卷I),5. to buy。“给父亲买礼物”是“从银行拿钱出来”的目的,作目的状语,用动词不定式。,to buy,6. His first book _ (publish) next month is based on a true story. (2010陕西卷),6. to be published。根据句中的next month可知是将出版,故要用不定式;又因为book与publish之间为被动关系,故要用不定式
18、的被动式。,to be published,7. I have a lot of readings _ (complete) before the end of this term. (2010山东卷),7. to complete。表示有事要做,用“have+宾语+不定式”结构,其中的不定式用作定语,修饰其前的名词。,to complete,8. Many buildings in the city need repairing, but the one _ first is the library. (2010重庆卷),8. to be repaired。表示首先要修理的那座建筑物,即表示
19、未来,用动词不定式;又the one与repair是被动关系,故用不定式的被动式。,to be repaired,9. _ (approach) the city center, we saw a stone statue of about 10 meters in height. (2010上海卷),9. Approaching。因we与approach是主动关系,所以用现在分词短语作状语。,Approaching,10. In many peoples opinion, that company, though relatively small, is pleasant _ (deal)
20、with. (2010四川卷),10. to deal。在形容词easy, hard, difficult, pleasant等后作状语,用动词不定式,且习惯上要用主动形式表示被动含义。,to deal,11. That is the only way we can imagine _ (reduce) the overuse of water in students bathrooms. (2010上海卷),11. to reduce。不定式在此用作定语,修饰the only way。其实,the only way还有两个定语,一个是we can imagine,另一个是to reduce
21、the overuse of water。,to reduce,12. I had great difficulty _ (find) the suitable food on the menu in that restaurant. (2010上海卷),12. finding。have difficulty (in) doing sth 为固定句式,其意为“做某事有困难”。,finding,13. Im calling to enquire about the position _ (advertise) in yesterdays China Daily. (2010北京卷),13. ad
22、vertised。由于position(职位) 与 advertise(登广告) 之间为被动关系,且广告昨天已经刊发了,故用过去分词作定语。,advertised,14. So far nobody has claimed the money _ (discover) in the library. (2010湖南卷),14. discovered。由于money与discover之间为被动关系,由句意可知,钱“已经”被发现,故用过去分词作定语。,discovered,15. Alexander tried to get his work _ (recognize) in the medica
23、l circles. (2010辽宁卷),15. recognized。考查“get+宾语+过去分词”结构。其中的“宾语”与其后的“过去分词”之间为被动关系。,recognized,16. Mrs. White showed her students some old maps _ (borrow) from the library. (2010全国卷I),16. borrowed。因maps与borrow之间为被动关系;再根据句意,地图是“已经”借来了,所以用过去分词作定语。,borrowed,17. Though _ (surprise) to see us, the professor
24、gave us a warm welcome. (2010全国卷II),17. surprised。因the professor与surprise是被动关系,故用“连词+过去分词”作状语。,surprised,18. _ (see) from the top of the tower, the south foot of the mountain is a sea of trees.

25、h a dining table already _(lay) for a meal to be cooked. (2010山东卷),19. laid。短语lay a table的意思是“摆桌子”,因句中的table与动词lay之间为被动关系,所以用过去分词作定语。,laid,20.
