20、 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现在分词的句法功能：,（2）现在分词作表语：The film being shown in the cinema is exciting. 正在这家上演的电影很棒。The presen
21、t 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： 如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。例如： Can you hear her singing the song in the next room?

(to talk是目的状语，指停下前一动作来进行talk)Remember, forget doing something (指已做过的事)Remember, forget to do something (指未做过的事),2 分词和动名词作定语的区别。分词往往表示它所修饰的词所做的动作，即逻辑主语是它所修饰的词；动名词往往表示与它所修饰的词有关的动作，即所修饰的词不能充当逻辑主语。例如：scorching heat (
31、= heat that is scorching) (炙人的热气) （分词） a sleeping car (= a car for sleeping) (动名词)a sleeping baby(=a baby who is sleeping) working method (= method of working)(动名词),3. 动词不定式作宾语补语和现在分词作宾语补语的区别动词不定式只说明宾语的一个动作，而分词则说明宾语的动作正在进行。例如： Just then he heard someone sing in the next room. (不定式) Just then he hear
32、d someone singing in the next room. (现在分词)4. 不定式, 现在分词, 过去分词做定语的区别:不定式表示即将发生的动作, 现在分词表示现在发生的动作, 过去分词表示已经发生的动作. The building to be completed next month is our library. (不定式) The building being built is our library. (现在分词) The building built is our library. (过去分词),四、独立主格结构,独立主格结构 (absoluteconstruction
33、)，又叫做独立结构。它在句法上游离于句子主体之外，跟主句没有任何句法联系，但在意义上却与主句紧密联系在一起，共同构成一个完整的语义环境。独立主格结构没有主语和谓语，只有逻辑上的主语。因此，它在句法上不是句子，而是一个独立于句子成分之外的独特结构。如：The teacher came in, book in hand.Book in hand, the teacher came in.独立主格结构分为四个类型: (1) 独立分词结构 (2) 独立不定式结构 (3) 独立无动词结构 (4) with复合结构,1. 独立分词结构 独立分词的构成是：“主格词分词”。主格词可以是代词、名词和名词词组；分
34、词可以是现在分词和过去分词的各种时态和语态。独立分词结构的句法功能是在句中做状语，相当于分词短语，表示谓语动词的时间、原因、条件、方式和和伴随状况。 Spring coming, the fields are full of life. 春天来了，田野里充满生机。（时间） Professor Wang being ill, the lecture was put off. 因为王教授生病了，报告被推迟了。（原因）,More time given, we should have done it much better.如果给我们更多的时间，我们会做得更好。（条件） The tourists vi
35、sited many scenic spots, the guide acting as interpreter. 导游做翻译，游客们游览了很多景点.（方式）The boy stood there, his right hand raised.那个男生坐在那里，右手高举。（伴随）,2. 独立不定式结构 独立分词结构表示的时间是发生在主句动词动作之前或同时发生。如果时间发生在主句动词动作之后或者还没有发生，就需要用独立不定式结构来表达。独立不定式结构的构成是：“主格词不定式”，主格词是代词、名词和名词词组。在独立不定式结构中，不定式多表示将来的动作行为或状态，有企图、约定等含义，指的是计划、安排
36、、假设的事情。,More time to be given, we will make full use of it. 再给一些时间，我们就会充分利用它。(将来时间，表示假设) Nobody to come tomorrow, we will have to put off the meeting till next week. 如果明天没有人来，我们将把会议推迟到下周。（将来时间，表示计划）,3. 独立无动词结构 独立无动词结构的构成是：“主格词非动词部分”。主格词可以是代词、名词和名词词组，非动词部分是名词（短语）、形容词（短语）、副词（短语）和介词（短语）。这种结构多用来表达对主句细节的
37、补充说明，对主句动词意义上的伴随，有时还用来表达事件发生的原因、时间等。,I heard that she got injured in the accident, my heart full of worry. 我听说她在这场事故中手了伤，内心充满担忧。 （形容词）（伴随） The murderer got into the house, a knife in his hand.凶手闯进房间，手里拿着刀。（介词短语）（伴随） The murderer got into the house, knife in hand. （介词短语）（伴随）,4. with复合结构 with复合结构比较常见，
38、它的构成是：“with宾语宾语补足语”。宾语由代词、名词和名词词组充当，宾补由分词、不定式、形容词、副词、介词短语、名词等充当。根据句意需要，with可换为without。 Holms and Watson sat with the light on for half an hour.福尔摩斯和沃森做着，让灯亮了半个小时。（介词短语）（伴随） Possibly this person died without anyone knowing where the coins were hidden. 也许这个人死了，谁也不知道钱币藏在哪里。（现在分词）（伴随）,He used to sleep with the door open.他过去常开着门睡觉。（形容词）（伴随） With the work done, he went home. 工作做完后，他回了家。（过去分词）（时间） With you to help us, we will finish the task in time. 由你来帮助，我们将会及时完成任务。(不定式）（条件）Hong Kong looks more beautiful with thousands of lights on at night. 夜里，香港万盏灯火，分外美丽。（副词）（伴随）,THE END Thank You,
