概念：动词-ing形式是动词的一种非谓语形式，包括现在分词和动名词两种。

动词-ing形式的时态和语态：语态时态主动语态被动语态一般式doingbeingdone完成式havingdonehavingbeendone

动词-ing形式在句中的语法作用：动名词在句中作主语、宾语、表语和定语，现在分词在句中作表语、状语、宾语补足语和定语。一、动词-ing形式作主语动词-ing形式作主语时，往往表示经常性、习惯性的动作，通常置于句首。Readingaloud

isagoodwaytolearnalanguage.大声朗读是学习语言的一种好方法。注意：①不定式作主语表示具体的或一次性的动作。eg:Tolietoheriswrong.对她撒谎不对。②动名词作主语时，谓语动词用单数。eg:Climbingmountainsisreallydifficultfortheold.对于老人来说爬山确实困难。二、动词-ing形式作宾语1.作动词的宾语常接动词-ing形式作宾语的动词可用下面的口诀帮助记忆：避免错过少延期(avoid，miss，postpone)建议完成多练习(advise/suggest，finish，practise)喜欢想象禁不住(enjoy，imagine，can’thelp)承认否定与嫉妒(admit，deny，envy)逃避冒险莫原谅(escape，risk，excuse)忍受保持不介意(stand，keep，mind)eg:Wouldyoumindopening

thewindow?你介意打开窗子吗？2.作动词短语的宾语常见的跟动词-ing形式作宾语的动词短语有：insiston，objectto，begoodat，befondof，leadto，putoff，giveup，lookforwardto，feellike，devote...to，get/beusedto，payattentionto，beworth等。eg:Heinsistedondoingitinhisownway.他坚持要按照自己的方法做。3.在有些动词的后面，如：start，begin，continue等既可接动名词也可接不定式作宾语，两者意义区别不大。eg:Theycontinuedworking/toworkasifnothinghadhappened.他们继续工作，似乎什么也没发生过。动词宾语的形式意义forgettodo忘记做……doing忘记做过……remembertodo记着要去做……doing记得做过……4.有些动词(短语)后跟不定式和动词-ing形式作宾语均可，但含义不同。常见的有：regrettodo遗憾/抱歉要做……doing后悔做了……trytodo尽力做……doing尝试做……meantodo打算做……doing意味着……goontodo接着做(另外一件事)doing接着做(同一件事)stoptodo停下来去做……doing停止做……5.下列动词可接动词-ing形式的主动形式表示被动意义，相当于不定式的被动形式。need/want/require/deservedoing＝need/want/require/deservetobedoneeg:Thebike

needsrepairing/toberepaired.这辆自行车需要修理。三、动词-ing形式作表语作表语的动词-ing形式包括现在分词和动名词。1.现在分词作表语，往往具有形容词的性质，说明主语的性质、特征等。作表语的现在分词，许多是由能够表示人们某种感情或情绪的动词变化而来的。常见的有：moving，interesting，encouraging，exciting，inspiring，boring，surprising，puzzling，amusing，astonishing...这类分词有“令人……的”的含义，常修饰物。eg:Theargumentisveryconvincing.这个论点很令人信服。Yourspeechisveryinterestingandencouraging.你的演讲很有趣而且很鼓舞人。注意：不定式和动词-ed形式也可作表语，但不定式通常强调一次性的、具体的、将要发生的动作，动词-ed形式则表示被动、完成含义。2.动名词作表语多表示抽象性的或习惯性的动作，一般说明主语的内容。eg:Herjobiskeepingthelecturehallascleanaspossible.

＝Keepingthelecturehallascleanaspossibleisherjob.她的工作是尽量使报告厅保持干净。四、动词-ing形式作定语及物动词-ing形式作定语被修饰的名词与非谓语动词为逻辑上的主动关系，动词-ing形式表示被修饰词的特征Ihaveneverseenamoremovingmovie.不及物动词-ing形式作定语表示动作正在进行Thewomansendingherchildrentoschoolismyhistoryteacher.五、动词-ing形式作宾语补足语常跟宾语补足语的谓语动词有see,watch,hear,set,keep,find,have,get等词。eg:Isawhimwalkinginthestreet.

我看见他在街上走。Iheardthemsingingintheclassroom.我听见他们在教室里唱歌。Wefoundtheboysleeping.我们发现小孩睡着了。六、动词-ing形式作状语动词-ing形式作状语时，可以表示时间、原因、结果、条件、让步、方式、伴随情况等，其前可加连词while,when,once,if,unless等。
