复习非谓语动词作定语、状语和补语一、非谓语动词作定语1．动词不定式作定语(1)动词不定式作定语，需放在被修饰的名词或代词的后面。动词不定式与所修饰词一般存在逻辑上的主谓关系、动宾关系或同位关系。
The man t help yu is Mr Smith．(the man will help yu)要帮助你的人是史密斯先生。I have a lt f wrk t d．(t d a lt f wrk)我有许多工作要做。The ability t express an idea is as imprtant as the idea itself．(the ability＝t express an idea)表达观点的能力与观点本身同等重要。
[温馨提示]动词不定式作定语，且与被修饰词有逻辑上的动宾关系时，动词不定式用及物动词；如果作定语的动词不定式是不及物动词，或者动词不定式所修饰的名词或代词是动词不定式动作的地点、工具等，动词不定式后需要加相应的介词。He has n pen t write with．他没有钢笔写字。
(2)当中心词为序数词、形容词最高级、the last、the nly等或被这些词修饰时，常用动词不定式作定语。It's agreed that the last persn t arrive pays fr the meal．大家一致同意最后到的人付餐费。(3)有些抽象名词后常用动词不定式作定语，这类名词常见的有ability，chance，pprtunity，plan，attempt等。The exhibitin is a unique pprtunity t see her later wrks.这次展览是观看她后期作品的难得的机会。
2．动词-ing形式(短语)和过去分词作定语(1)动词-ing形式(短语)和过去分词作定语往往具有形容词的性质。单个的动词-ing形式(短语)和过去分词作定语经常置于所修饰词之前；动词-ing形式(短语)短语和过去分词短语作定语经常置于所修饰词之后。He pured sme biled water int the bttle．他往瓶子里倒了一些开水。The huse standing n the nrth bank f the river was built in 1955．河北岸的那所房子是1955年建的。
(2)动词-ing形式(短语)作定语表示被修饰名词的某种用途或性能，常置于所修饰词的前面。a walking stick拐杖a sleeping bag睡袋a parking lt停车场cking il食用油
(3)动词-ing形式(短语)作定语，与所修饰词之间存在逻辑上的主谓关系，表示事物存在的状态或动作正在进行。They built a way leading t the muntains．他们建了一条通往山里的路。(4)过去分词(短语)作定语，与所修饰词之间存在逻辑上的动宾关系，表示被动或完成。The players selected frm the whle cuntry are expected t bring us hnur in this summer game．从全国选拔出来的运动员有望在今年夏天的比赛中为我们带来荣誉。
二、非谓语动词作状语非谓语动词作状语时，非谓语动词的逻辑主语必须与句子的主语保持一致。1．动词不定式作状语动词不定式可以起副词作用，在句中作状语。动词不定式可以作目的状语、结果状语、原因状语等。
(1)动词不定式作目的状语动词不定式作目的状语，意为“为了……；以便于……”，常用t d，in rder t d，s/such as t d等结构。We will cntinue ur campaign t prevent and cntrl air pllutin t make ur sky blue again．我们将继续我们防治空气污染的运动，以使我们的天空再次蔚蓝。T avid any delay，please phne yur rder directly．为避免延误，请直接打电话订购。
[温馨提示]强调动词不定式所表示的目的时，可用in rder t或 s as t接动词原形，但s as t不用于句首。动词不定式作目的状语可转换为 s that/in rder that或s ...引导的目的状语从句。He gt up early in rder t catch the first bus．他早起是为了赶上第一班公共汽车。The bus stpped s as t pick up passengers．公共汽车停下来以便搭载乘客。
He wrked very hard t pass the exam．→He wrked s hard that he culd pass the exam．→He wrked hard s that/in rder that he culd pass the exam．他努力学习是为了通过考试。
(2)动词不定式作结果状语动词不定式作结果状语常表示出乎意料的结果，常用于下列结构中：nly t d，enugh t d，t d ...，s/such t arrived at the shp nly t find I'd left all my mney at hme．我到达商店却发现钱全落在家里了。He is t tired t stay up any lnger．他太累了以至于不能再熬夜了。
(3)动词不定式作原因状语动词不定式在某些表示喜、怒、哀、乐等的形容词后作原因状语，用以说明产生这种情绪的原因。常见的这类形容词有srry，surprised，glad，disappinted，excited，happy等。He was glad t be hme again．再次回到家里，他感到很高兴。
2．动词-ing形式和过去分词作状语动词-ing形式和过去分词作状语表示时间、原因、结果、条件、让步、方式或伴随情况，相当于状语从句。(1)作时间状语Seen frm the hill，ur twn lks beautiful．从山上看，我们的城镇很美。When crssing the street，yu must be careful．过马路时，你必须小心。
(2)作原因状语Being ill，he didn't g t schl yesterday．由于生病，他昨天没去上学。(3)作结果状语(过去分词无此用法)Fifteen millin trees had been blwn dwn by the high winds，blcking rads，paths and railway lines．1 500万棵树被狂风刮倒，大小道路和铁路线都堵塞了。[温馨提示]动词-ing形式作结果状语表示自然而然的结果。
(4)作条件状语Given mre time，we culd have dne it better．如果给我们更多的时间，我们会做得更好。(5)作让步状语Warned f the danger，he still went skating n the thin ice．虽然被警告有危险，但他仍然去薄冰上滑冰。(6)作方式或伴随状语Mary std at the schl gate waiting fr Betty．玛丽站在学校门口等贝蒂。
三、非谓语动词作补语1．作宾语补足语(1)动词不定式作宾语补足语下列动词或词组后面要跟动词不定式作宾语补足语：frbid，advise，allw，ask，beg，cause，encurage，expect，persuade，prefer，frce，get，intend，invite，remind，require，teach，tell，want，depend n等。Yu are nt allwed t smke here．这里不允许抽烟。The dctr warned him nt t eat t much meat．医生告诫他不要吃太多的肉。
[温馨提示]下列动词(短语)接省略t的动词不定式作宾语补足语：一感(feel)，二听(hear，listen t)，三让(let，have，make)，四看(see，ntice，bserve，watch)。(2)动词-ing形式(短语)和过去分词作宾语补足语动词-ing形式(短语)和过去分词一般只在两类动词(短语)后作宾语补足语：
①感觉、感官、意愿动词(短语)：see，bserve，ntice，watch，lk at，hear，listen t，smell，feel，find，want，wish等。②使役动词：have，make，get，leave，keep，set等。When I pened the dr，I fund the grund cvered by fallen leaves．当我打开门时，我发现地上覆盖着落叶。I saw him entering the bank．我看见他正走进银行。I had my bike repaired yesterday．昨天我修了我的自行车。
2．作主语补足语动词不定式作主语补足语时，同句子的主语是逻辑上的主谓关系。动词-ing形式(短语)作主语补足语时，说明主语的状态、动作等。He was cnsidered t have prspects．人们认为他有前途。Tm was caught sleeping in class．汤姆被抓到在课堂上睡觉。
[温馨提示]带有宾语补足语的句子变为被动句时，原来的宾语成为被动句的主语，原来的宾语补足语变成主语补足语。若宾语补足语为省略t的动词不定式，句子变为被动句时，动词不定式符号t要还原。Smene bserved him enter the reading rm．→He was bserved t enter the reading rm．有人看见他进了阅览室。
