一、动词不定式的语法功能1.动词不定式可以在句中作主语、表语、宾语等。As the saying goes，“To see is to believe.”俗话说，“眼见为实”。The place he wanted to go is the Summer Palace.他想去的地方是颐和园。
语法精析
2.需要注意的几个问题(1)动词不定式短语作主语时，往往放在谓语之后，用it作形式主语。It is right to give up smoking.戒烟是对的。(2)动词不定式短语作宾语时，如果还带有宾语补足语，往往把动词不定式放在宾语补足语之后，而用it作形式宾语。I find it very interesting to study English.我发现学英语很有趣。
(3)能直接跟带to的动词不定式结构的动词主要有agree，ask，choose，demand，decide，expect，fail，forget，hope，help，learn，love，manage，offer，plan，prepare，pretend，promise，refuse，stop，wish，want等。This weekend I’m free and therefore I want to go to the movies with you.这个周末我有空，因此我想跟你一起去看电影。Don’t forget to turn off the light before you leave.离开前别忘了关灯。
二、动词-ing形式的语法功能(一)动词-ing形式作主语1.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。Reading aloud is a good way to learn a language.大声朗读是学习语言的一种好方法。Wasting a person’s time is the same as killing him for his property.浪费别人的时间无异于谋财害命。
[温馨提示](1)动词不定式作主语表示具体的或一次性的动作。To lie to her is wrong and you can’t do that any more.对她撒谎不对，你不能再那样做了。(2)动名词作主语时，谓语动词用单数。Climbing mountains is really difficult for the old like him.对于像他那样的老人来说，爬山确实困难。
2.形式主语it代替动词-ing形式作主语此类句式常见的有：It’s a waste of time doing sth. 做某事是浪费时间。It’s useless/worthwhile doing sth. 做某事没用/是值得的。It’s no good/use/fun doing sth. 做某事没用/没意思。It is no use waiting for other people to make decisions for you.等别人替你做决定是没有用的。It is a waste of time persuading such a person to join us.劝说这种人加入我们是浪费时间。
(二)动词-ing形式作宾语1.作动词的宾语常接动词-ing形式作宾语的动词有avoid，miss，postpone，advise，suggest，finish，practise，enjoy，imagine，admit，deny，envy，escape，risk，excuse，stand，keep，mind等。Would you mind opening the window?你介意打开窗户吗？I don’t like watching television but I enjoy listening to the radio.我不喜欢看电视，但是喜欢听收音机。It was obvious that he tried to avoid answering my questions.很明显他试图对我的问题避而不答。
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：insist on，object to，be good at，be fond of，lead to，put off，give up，look forward to，feel like，devote to，get/be used to，pay attention to等。He insisted on doing it in his own way.他坚持要按照自己的方法做。
[温馨提示](1)在有些动词的后面，如：start，begin，continue等既可接动名词也可接动词不定式作宾语，两者意义区别不大。They continued working/to work as if nothing had happened.他们继续工作，仿佛什么也没发生过。(2)在love，hate，prefer，like等动词后接动词-ing形式作宾语指经常性的动作，用动词不定式作宾语指具体的动作。He preferred staying in the house when it rained.下雨时他宁愿待在家里。(用动词-ing形式作宾语，指每逢天下雨都待在家里)
I prefer to stay at home this afternoon.今天下午我宁愿留在家里。(用动词不定式作宾语，表示今天下午留在家里这一具体的动作)(3)有些动词(短语)后跟动词不定式和动词-ing形式作宾语均可，但含义不同。常见的有：
Please remember to give my best regards to your family.请记着代我向你的家人问好。I still remember visiting the museum for the first time.我仍记得第一次参观博物馆的情景。I meant to pay a visit to you the other day.前几天我打算去拜访你。Missing the train means waiting for another hour.错过了这班火车就意味着再等一个小时。
(4)下列动词可接动词-ing形式的主动形式表示被动意义，相当于动词不定式的被动形式。need/want/require/deserve doing＝need/want/require/deserve to be doneThe bike needs repairing/to be repaired.这辆自行车需要修理一下。
(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：amusing，astonishing，boring，encouraging，exciting，inspiring，interesting，moving，puzzling，surprising等，这类分词有“令人……的”的含义，常修饰物。The argument is very convincing and we are all convinced of you.这个论点很令人信服，我们都相信你。I can tell you that your speech is very interesting and encouraging.我可以告诉你，你的演讲很有趣而且很鼓舞人。
[名师点津] 动词不定式和动词-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。Her job is keeping the lecture hall as clean as possible.＝Keeping the lecture hall as clean as possible is her job.她的工作是尽量使报告厅保持干净。
三、过去分词作表语1.意义：用在系动词后面，构成系表结构，表示主语所处的状态。It seemed that she looked disappointed.她似乎看上去很失望。There’s no doubt that we were encouraged at the news.毫无疑问，听到这个消息我们很受鼓舞。2.过去分词作表语表示主语所处的状态。这一结构从形式上与被动语态相同，但被动语态强调主语所承受的动作。试比较：
The book is well written.这本书写得很好。The book was written by a soldier.这本书是由一位士兵写的。
3.感觉类及物动词的现在分词与过去分词作表语的区别英语中有很多与感觉有关的及物动词，其现在分词表示主动意义，即“令人有某种感觉的”，多用来修饰物；其过去分词含有被动意义，即“人被引起某种感觉的”，多用来指人、人的声音、笑容或表情等。如：
surprising令人吃惊的surprised感到吃惊的
discouraging令人泄气的discouraged感到泄气的
返 回
We were surprised at what he said at the meeting.我们对他在会上讲的话很是惊讶。His words were discouraging，which made many people discouraged.他的话令人泄气，使很多人灰心丧气。
