How did you manage to finish it so soon?如果不定式（宾语）后面有宾语补足语，则用it作形式宾语，真正的宾语（不定式）后置，放在宾语补足语后面，常见的词有：think feel expect make suppose imagine 例如： Marx found it important to study the situation in Russia. 动词不定式也可充当介词宾语，如： I have no choice but to stay here. He did nothing last Sunday but repair his bike. 有些动词常用代疑问词的不定式作宾语，例如：teach,remember,advise,show,advise,show,know,forget,learn,understand,see,hear,find out,explain,decide,discuss等动词不定式前有时可与疑问词连用，如： He gave us some advice on how to learn English.They havent decided when to leave so far. （4）作宾语补足语： 在复合宾语中，动词不定式可充当宾语补足语，补充说明作宾语的名词或代词的动作或状态，如下动词常跟这种复合宾语：want, wish, ask, tell, order, beg, permit, help, advise, persuade, allow, prepare, cause, force, call on, wait for, invite, invite, warn, expect, prefer, encourage等Their parents prefer them to be home early.My parents dont allow me to go out at night.（5）作定语： 动词不定式作定语，放在所修饰的名词或代词后。与所修饰名词有如下关系： 1.动宾关系： I have a meeting to attend. 注意：不定式为不及物动词时，所修饰的名词如果是地点、工具等，应有必要的介词，如： He found a good house to live in. The child has nothing to worry about. What did you open it with? 如果不定式修饰time, place, way，可以省略介词： He has no place to live. This is the best way to work out this problem. 如果不定式所修饰名词是不定式动作承受者，不定式可用主动式也可用被动式： Have you got anything to send? 你要送什么东西吗？ (你自己去送)Have you got anything to be sent? 你有什么东西需要送吗？ （别人替你送） 2.被修饰名词是不定式逻辑主语： He is the first to get here. 6）作状语： 表目的，常译成 为了 ，不定式一般放在被修饰词之后，但为了强调目的也可放在句首。为了加强语气，还可用in order to 或so as to.We should do whatever we can to help them.We took an umbrella so as not to get wet.注意不定式放句首时，逻辑主语与句子主语要一致： wrong：To save money, every means has been tried. right：To save money, he has tried every means. wrong：To learn English well, a dictionary is needed. right：To learn English well, he needs a dictionary.表结果(往往是与预期愿望相反的结果)： only to do sthHe arrived late only to find the train had gone. I visited him only to find him out. 表原因： They were very sad to hear the news. 表程度： Its too dark for us to see anything. The question is simple for him to answer. （7）作独立成分： To tell you the truth, I dont like the way he talked.不定式省略to的几种情况： （1）在cannot but, cannot choose but 与cannot help but 之后的不定式一般都不带to, 常翻译为“不得不”。例如： I cant but admire her courage. 我不能不钦佩她的勇气。 He cant choose but do it. 他只好做这件事了。 I cant help but love her. 我不禁爱上了她。 （2）在连词but之前如有动词do, 其后的不定式不用to, 即：do nothing but+动词原形，译为“只”；但如果连词but之前的动词不是do，其后的不定式一般要带to，例如： He does nothing but complain. The workers do nothing but drink tea and talk to each other. He had no choice but to accept the fact. (3) 有些动词如make, let, have等使役动词后用作宾语补足语的不定式必须省略to 如： He had his son clean the car. Rain makes plants grow. 当使役动词用于被动语态时，要补上在主动语态中省略的to (主要指make)， He was made to work long hours. (4)在see, hear, observe, notice, feel, watch 等感官动词后用作宾语补足语的不定式必须省略to. She noticed the man look at her a couple of times. I felt something crawl up my arm. 注：若这些动词用于被动语态或不定式用于完成式，其后的不定式要带to，如： I noticed her to have come early. He was seen to enter the building. 注：若动词feel后用作宾语补足语的不定式为to be, 则要带to, 如 They felt the plan to be unwise. (5)在动词help后用作宾语或宾语补足语的不定式可以不带to, I helped him (to) repair his bike. 当help用于被动语态时，不定式前的to不能省。 The boy was helped by a woman to collect his scattered coins. （6）不定式的并列：第二个不定式可省略to。 He wished to study medicine and become a doctor. （7）不定式的省略：保留to省略do动词。 If you dont want to do it, you dont need to. 不定式用主动表示被动的几种常见情形 （1）不定式to blame, to let用作表语时，通常要用主动表被动。如： The house is to let. 此屋出租。 Mr Green stood up in defence of the 16-year-old boy, saying that he was not the one to blame （2）某些”be+adj+to do”结构中的不定式通常要用主动形式表示被动意义。如： The book is difficult to understand. The work is impossible to finish in a week. 注：这类结构的特点是句子主语就是其后不定式的逻辑宾语，按理说其中的不定式要用被动形式，但习惯上却要用主动表被动。这类形容词常见的有awkward, convenient,dangerous, difficult, easy, hard, impossible, interesting, nice, pleasant, safe, tough, tricky, unpleasant 等。 （3）在tooto do sth和enough to do sth这两个结构中，若句子主语与其后的不定式to do sth为被动关系，则该不定式通常用主动形式表示被动意义（但有时也可直接用被动式）。如： The writing is too faint to read (to be read). 这笔迹太模糊，看不清。 These boxes are not strong enough to use (to be used) as a platform.注意 ： 句型：cannot help but do sth cannot but do sth cannot choose but do sth can do nothing but do sth have no choice/alternative but to do sth上述句型的意思接近，即“不得不做”、“不禁做”、“不由自主地做”、“不能不做”、“只能做”。其共同的特点是都有一个否定词和but。如：Nobody can help but be fascinated by the world into which he is taken by the science fiction.When I consider how talented he is as a painter, I cannot help but believe that the public will appreciate his gift.现在分词现在分词既具有动词的一些特征，有时态和语态的变化，又具有形容词和副词的句法功能，在句中做表语、定语、状语、补语。1现在分词的形式：现在及 物 动 词 write不及物动词go分词主动语态被动语态主动语态一般式writingbeing writtengoing完成式having writtenhaving been writtenhaving gone否定式：not + 现在分词（1）现在分词的主动语态：现在分词主动语态的一般式表示与谓语动词所表示的动作同时发生；完成式表示的动作在谓语动词所表示的动作之前发生，常作状语。e.g.They went to the park, singing and talking. 他们边唱边说向公园走去。Having done his homework, he played basket-ball. 做完作业，他开始打篮球。（2）现在分词的被动语态：一般式（being done）表示与谓语动词同时发生的被动的动作，完成式（having been done）表示发生在谓语动词之前的被动的动作。e.g.The problem being discussed is very important. 正在被讨论的问题很重要。Having been told many times, the naughty boy made the same mistake.被告诉了好几遍，这个淘气的孩子又犯了同一个错误。2现在分词的句法功能（1）作定语：现在分词作定语，当分词单独做定语时，放在所修饰的名词前；如果是分词短语做定语放在名词后。e.g.In the following years he worked even harder. 在后来的几年中，他学习更努力了。The man speaking to the teacher is our monitors father. 正与老师谈话的那个人是我们班长的父亲。现在分词作定语相当于一个定语从句的句法功能，如：in the following years也可用in the years that followed, the man speaking to the teacher可改为the man who is speaking to the teacher.（2）现在分词作表语：e.g.The film being shown in the cinema is exciting. 正在这家上演的电影很棒。The present situation is inspiring. 当前的形势鼓舞人心。“be + doing”既可能表示现在进行时，也可能是现在分词做表语，它们的区别在于“be + doing”表示进行的动作是进行时，而表示特征时是系动词be与现在分词构成系表结构。（3）作宾语补足语以下动词后可跟现在分词作宾语补足语：see, watch, hear, feel, find, get, keep, notice, observe, listen to, look at, leave, catch等。e.g.Can you hear her singing the song in the next room? 你能听见她在隔壁唱歌吗？He kept the car waiting at the gate. 他让小汽车在门口等着。（4）现在分词作状语作时间状语e.g.(While) Working in the factory, he was an advanced worker. 在工厂工作时，他是一名先进工人。作原因状语e.g.Being a League member, he is always helping others. 由于是共青团员，他经常帮助他人。作方式状语，表示伴随e.g.He stayed at home, cleaning and washing. 他呆在家里，又擦又洗。作条件状语e.g.(If) Playing all day, you will waste your valuable time. 要是整天玩，你就会浪费宝贵的时间。作结果状语：e.g.He dropped the glass, breaking it into pieces. 他把杯子掉了，结果摔得粉碎。作让步状语 e.g.Though raining heavily, it cleared up very soon. 虽然雨下得很大，但不久天就晴了。过去分词过去分词只有一种形式：规则动词由动词原形加词尾-ed构成。不规则动词的过去分词没有统一的规则 过去分词的句法功能： 1过去分词作定语： Our class went on an organized trip last Monday. 上周一我们班开展了一次有组织的旅行。 Those selected as committee members will attend the meeting. 当选为委员的人将出席这次会。 注意当过去分词是单词时，一般用于名词前，如果是过去分词短语，就放在名词的后面。过去分词做 定语相当于一个被动语态的定语从句。 2过去分词作表语： The window is broken. 窗户破了。 They were frightened at the sad sight. 他们对眼前悲惨的景象感到很害怕。 注意：be + 过去分词，如果表示状态是系表结构，如果表示被动的动作是被动语态。区别： The window is broken.（系表） The window was broken by the boy.（被动） 有些过去分词是不及物动词构成的，不表示被动，只表示完成。如： boiled water（开水） fallen leaves（落叶） newly arrived goods（新到的货） the risen sun（升起的太阳） the changed world（变了的世界） 这类过去分词有：gone, come, fallen, risen, changed, arrived, returned, passed等。 3过去分词作宾语补足语： I heard the song sung several times last week. 上周我听见这首歌被唱了好几次。 4过去分词作状语： Praised by the neighbours, he became the pride of his parents. 受到邻居们的表扬，他成为父母的骄傲。（表示原因） Once seen, it can never be forgotten. 一旦它被看见，人们就忘不了。（表示时间） Given more time, Ill be able to do it better. 如果给予更多的时间，我能做得更好。（表示条件） Though told of the danger, he still risked his life to save the boy. 虽然被告之有危险，他仍然冒生命危险去救那个孩子。（表示让步） Filled with hopes and fears, he entered the cave. 心中充满了希望与恐惧，他走进山洞。 独立主格结构 独立主格结构（Independent Genitive）有两部分组成，前一部份是名词或者代词，后一部分是非谓语动词(不定式、动名词和分词)或形容词、副词、或介词短语。前后两部分具有逻辑主谓关系。独立主格结构在句中做状语，多用于书面语。 独立主格结构本身不是句子，在句子中作状语，表示时间、原因、条件、伴随、目的等。形式:1.名词/主格代词+现在分词名词/主格代词与现在分词之间是主谓关系。如： The girl staring at him (= As the girl stared at him，表原因), he didnt know what to say. 姑娘两眼望着他，他不知道说什么好。 Time permitting (= If time permits，表条件), we will go for an outing tomorrow. 如果时间允许的话，我们明天去郊游。 2.名词/主格代词+过去分词名词/主格代词与过去分词之间是动宾关系。如： The problems solved (= As the problems were solved，表时间), the quality has been improved. 随着问题的解决，质量已经提高了。 Her glasses broken (= Because her glasses were broken，表原因), she couldnt see the words on the blackboard. 由于眼镜摔坏了，她看不见黑板上的字。 3.名词/主格代词+不定式名词/主格代词与不定式之间是主谓关系，且强调的是一次具体性的动作。如： He is going to make a model plane, some old parts to help. 借助于一些旧零件，他要做一个飞机模型。 They said good-bye to each other, one to go home, the other to go to the bookstore. 他们道别后，一个回了家，一个去了书店。 4.名词/主格代词+形容词如： An air accident happened to the plane, nobody alive. 那架飞机遭遇了空难，无一人生还。 So many people absent, the meeting had to be called off. 这么多人缺席，会议不得不取消。 5.名词/主格代词+副词如： The meeting over, they all went home. 会议一结束，他们就都回家了。 6.名词/主格代词+介词短语如： The boy goes to the classroom, book in hand. 那男孩手里拿着书去教室。 Mary was sitting near the fire, her back towards the door. 玛丽靠近火炉坐着，背对着门。 7.
