(表结果)He tried only to fail.（结果没有成功） She was happy to hear the news. (表原因)不定式常用于修饰下列形容词: able,afraid,angry, anxious, apt, careful, careless, certain, clever, considerate, delighted, difficult,eager, easy, fit, frightened , happy, interesting, likely, lucky, quick, ready, reluctant , right, sorry, surprised, sure, thoughtful, thoughtless, unable, unwilling, wrong etc.例如：French is difficult to learn. 法语难学。Im sorry to interrupt you, but I have to.(5)作独立副词成分。例如：To speak frankly, I dont like your attitude.(6)与疑问词连用。疑问代词who, what, which和疑问副词when, where, how等后加动词不定式，构成不定式短语，可在句子中作主语、宾语、表语等成分。例如：When to start has not been decided.什么时候出发还没有定。The problem is how to get there on time.问题是怎样才能准时到达哪儿。注：在有些动词后常用疑问词 + 动词不定式的结构。这类动词有：know, ask, tell, show, wonder,consider, understand, learn, instruct, guess, see, explain, discover, imagine, think, hear 等。例如：He didnt know what to do next.I havent decided whether to go to Japan.我没有决定是否到日本去。不定式的复合结构由for + 名词或代词 + 动词不定式构成的复合结构在句中可作主语、表语、宾语、状语等。例如：It is necessary for you to finish the work before Friday.你们有必要在星期五前做完这项工作。His idea is for us to travel in different cars.他的主意是让我们乘不同的车去旅游。由of 引出的不定式复合结构，经常与以下形容词连用：bold, brave, careless, civil, clever, courageous, foolish, good, honest, kind, nice, rash, right, rude, stupid, silly, thoughtful, thoughtless, wrong, wise等。例如：Its kind of you to say so.Its brave of you to go into the burning building to save the baby!你真勇敢，冲进着火的大楼里救这个婴儿不带to 的动词不定式(1)在有些使役动词及感官动词后可用省略to的动词不定式，如let, make, have, hear, see, feel, smell, hear, watch等。例如：The teacher often makes me rewrite the composition.老师常常让我把作文重写。将该句转换成被动语态：I am often made by the teacher to rewrite the composition.I heard her say that she was fed up.(2)在下列结构后常用不带to的动词不定式：had better, would rather, can not but, cannot help but, do nothing but等。例如：Id better go now, or Ill miss the train.They can not but accept his advice.我只好接受他的建议。(3)在except, but 之前有动词do作实义动词，则except, but 后一般接不带to的动词不定式，反之则接带to 的动词不定式。例如：We have no choice but to wait.我们除了等待别无选择（我们只好等待）。There is no choice but to go there.There is nothing to do but to (to 可省略) read a book.(4) 在why, why not结构中，紧接其后的动词不定式不带to例如：Why argue with him?Why not send those books back?为什么不把那些书送回去？（二）动名词在句中充当的成分(1)作主语例如：Asking for help is sometimes necessary. 请求帮助有时是必要的。Eating too much is not good for your health.吃得太多对你的健康不利。Teaching offers something besides money and power.(2)作补语、表语例如：Seeing is believing.We call such an act cheating.我们称这样的行为为作弊/欺骗行为。(3)作以下及物动词及词组的的宾语mind，finish，enjoy，suggest，permit，appreciate，consider，miss，dislike，keep(on)，avoid，permit，imagine，risk，escape，admit，stand(忍受)，allow，forbid，excuse，等等。短语动词：give up，put off，look forward to，feel like，insist on，object to，preventfrom，set about，cant help，be/get used to等；短语：be worth doing，be no good doing，be no use doing，be busy doing等例如：The mother did agree to let the boy risk swimming across the river.冒险游过河His wife doesnt allow smoking inside the room but allows him to smoke outside the room.他的妻子不允许在室内抽烟，但是允许他在室外抽。All of them insisted on my staying with them a few days longer.他们所有的人都坚持要我再跟他们多呆几天时间。Im looking forward to hearing from you soon.Being ill for a few days,she doesnt feel like eating anything.不想吃任何东西另在want, need, require等动词后，常用动名词的主动形式表示被动的意思（主语与动名词之间存在逻辑上的动宾关系）。例如：My hair needs cutting. (= My hair needs to be cut.)(5) 作定语。它与被修饰词之间没有逻辑上的主谓关系，通常只表示用途或与所修饰的名词有关的动作。例如：The factory built a swimming pool last year.游泳池Our teacher uses a very good teaching method.教学方法(6) 作同位语。例如：His hobby, making model airplanes, is very interesting.动名词的复合结构动名词的复合结构由物主代词或名词所有格 + 动名词构成。如果不是在句子开头，这种结构常可以由名词的普通格或人称代词宾格 +动名词构成， 在句中可作主语、宾语等。例如：Do you mind my closing the door?

(= The snow was boring, so the boys wee bored and went home.)China is a developing socialist country.发展中的社会主义国家The man writing the obituary (讣告) is my friend. (= The man who is writing the obituary is my friend.)The broken glass scattered on the ground.破杯注：现在分词与过去分词都可作定语，但现在分词表达的是正在进行的事情，有主动意义；而过去分词表示的是已完成的事情，有被动意义。(2)作表语、宾语补足语。能带分词作宾补的动词常见的有see, hear, keep, find, notice, watch, think, want, smell, observe等。例如：The story is boring.I found him reading a novel. 在读小说(现在分词作宾语补足语)I found him surrounded by a group of children.一群孩子包围着 (过去分词作宾语补足语)(3)作状语。分词作状语可以表示时间, 原因, 条件, 结果, 伴随情况。 例如：Having read all the required papers, he answered the questions fluently. -时间Being short of money, I decided to apply for the work. -原因Seriously injured, Allen was rushed to the hospital. -原因If going there by plane, well have to pay twice as much.条件Unless asked to answer questions, the pupils were not supposed to talk in Mrs Smiths class.条件The farmer useda new insecticide, thus raising the average yield by 15%. 结果He sat in a rocking chair, watching TV. -伴随分词的特殊结构独立主格有时分词的逻辑主语与主句主语不一致，这时分词须带上自身的主语，这种结构称为独立主格结构。这种结构在句中多作伴随状语。亦可用来表示时间、原因、条件等。例如：That being the case, wed better make some changes in the plan.Weather permitting, we will go out. = if weather permitsThe teacher having finished the lesson, the students left the classroom.“with或without + 名词或代词 + 分词”的复合结构常用作补充说明或表示伴随情况。例如：He fell asleep with the lamp burning.某些固定结构generally / frankly speaking ,judging from / by 中，分词的逻辑主语与句子的主语不一致，这种结构只限于为数很少的几个动词。例如：Judging by his dress, he comes from a wealthy family.从他的衣着判断Frankly speaking, I dont like him at all.坦率地说catch+宾语+doing例如：I caught them stealing my apples我抓住他们偷我的苹果。If she catches me reading her diary，shell be furious.如果她抓住我偷看她的日记，她会愤怒的注：有些现在分词可以作介词用：如concerning, considering, regarding, respecting等。 例如：Considering his age, he is tall.考虑了他的年龄I have nothing to say concerning his speech.关于他的演讲三、非谓语动词比较1做主语宾语：-般来说，不定式和动名词成份相同时，表示客观性、一般性行为多用动名词表示，而表示一次性、具体性行为则多用不定式。Looking after children is her job.照看小孩To clean the classroom is his job today.打扫教室I like swimming, but I dont like to swim today because I dont feel well.注意（1）：begin和start本身为进行时，或后面动词为心理变化意义的动词时，须接不定式。 When we came in, they were beginning to have supper. After his explanation, I began to understand it / realize that I was wrong. (2).有些词后面既可以接不定式亦可接动名词，但其意义有很大区别，须特别注意： Aremember，forget，regret接动名词，表示完成意义(=having done)，接不定式，表示将来意义： Please remember to bring me the book I want next time. I remember seeing her (=having seen her) somewhere before. Dont forget to write to me soon. I never forget visiting (=having visited) them for the first time.

The door is locked now. The children are well dressed these days.4.做定语： 不定式做定语与先行词有动宾、主谓和解释先行词内容等关系。在时态上常是将来意义，现在分词做定语是现在时或进行时态意义；过去分词做定语则是完成时态意义。此外，不定式做定语时只能后置，不可前置，而单个分词做定语可前置，分词短语做定语则须后置。动名词做定语，须前置，且要重读，它表明先行词的用途。而分词做定语表明先行词的性质、特征和状态。 a swimming boy=a boy who is swimming a swimming pool=a pool for swimming the boiling water=the water that is boiling drinking water=water for drinking Today I have a letter to write.Please find a man to help us.
