A. to return B. returning C. return D. to returning 59课堂教学分词的句法作用分词的句法作用 1.作定语 单个分词作定语一般放在它所修饰的名词前，但有时也可放在名词后；分词短语作定语必须放在被修饰的名词后，但由“副词+分词”构成的短语则放在它所修饰的名词前。如果被修饰的中心词是分词表示的动作的发出者，则用现在分词作定语；如果被修饰的中心词是分词表示的动作的承受者，则用过去分词作定语。例如：60课堂教学The question discussed at the meeting is quite confidential.会上

50、所讨论的问题是十分机密的。The question being discussed at the meeting is quite confidential.会上正在讨论的问题是十分机密的。The question to be discussed at the meeting is quite confidential.会上要讨论的问题是十分机密的。 61课堂教学2）注：动名词作定语与现在分词作定语的区别：现在分词作定语表示所修饰的名词的动作。例如：flying fish飞鱼 a running dog走狗 a falling tide落潮 a crying boy哭着的孩子 比较：teach

51、ing method swimming pool62课堂教学2.作宾语补足语 现在分词作宾语补足语表示动作正在进行，宾语是动作发发出者；过去分词做宾语补足语具有被动意义，宾语是动作的承受者。可带宾语补足语的常用动词有see, watch, hear, find, notice, leave, smell, have, get, make等。要特别注意，在由“have, get, see +直接宾语+过去分词”的句型中，表达的动作不是由主语所指的人做的，而是由别人做的。例如：My hair is too long. I am going to have it cut.我头发太长了，我要去（请人）

52、理发。63课堂教学The woman teacher giving us oral lessons is from America.Did you see the man talking (=who was talking ) to the headmaster?the book written by Lu Xun注：1）分词作定语与动词不定式作定语的区 别是：现在分词表示主动，进行之意，过 去分词表示被动与完成，而不定式表示在 谓语动词表示的动作之后即将发生的动作。例如：64课堂教学He was found standing at the corner of that street.4.作状

53、语 分词及分词短语作状语可表示时间，原因，条件，结果，让步，方式或伴随情况。分词（短语）可以放在句首也可放在句末，通常用逗号与句子其他部分隔开。分词前可带“when, while, as, once, until, if ”等连接词。例如：Walking along the street, we found a purse lying on the ground. 65课堂教学Being very tired, he fell asleep immediately.Praised by the teacher of English, he has worked even harder at E

54、nglish than ever.The teacher entered the classroom, followed by his students.注意分词及其逻辑主语（即主句主语）的一致性。逻辑主语应为现在分词表示的动作的发出者或为过去分词表示动作的承受者，不能说：Looking out of the window, a car is running.66课堂教学5、作表语现在分词作表语多表示主语具有的特征；过去分词作表语多表示主语的状态，要特别注意区分下述常用现在分词与过去分词。如 amazing (令人惊异的) amazed （感到惊讶）exciting （令人激动） excite

55、d （感到激动）interesting （有趣的） interested （感兴趣）surprising （令人惊异的） surprised （感到惊异） boring （令人厌烦的） bored （感到厌烦） inspiring （令人鼓舞的） inspired （受鼓舞） moving （令人感动的） moved （受感动） discouraging （令人沮丧的） discouraged （感到沮丧）67课堂教学He heard the bell ringing. We found the path covered with snow.3.作主语补足语如果把分词作宾语补足语的句中的谓语由

56、主动语态改为被动语态，则宾语补足语就变成了主语补足语。例如：The machine must be kept running at full speed.68课堂教学分词的时态和语态分词的时态和语态1构成（以study和go为例） 及物与不及物动词 语态 时态 类别 及 物 动 词 不及物动词主动语态 被动语态 主动语态现在分词一般式 studying being studied going完成式 having studied having been studied having going过去分词一般式 studied gone2用法69课堂教学(1) 一般式：现在分词的一般式说明分词表示的

57、动作和句中谓语动作同时发生或表示分词表示的动作发生后，句中谓语动作立刻发生；过去分词的一般式说明分词表示的动作在句中谓语动作之前发生或者某些持续性动作的分词表示与句中谓语动作并无先后之分。例如：One day a few weeks later I found myself sitting in a village house， facing an old man of about eighty. 70课堂教学Compared with her achievements, her shortcomings are, after all, only secondary.(2) 现在分词的完成式：

58、现在分词的完成式表示的动作在句中谓语动作之前发生，具有主动意义。例如：Having finished reading the book, she put it aside. Not having received an answer, I wrote again.71课堂教学(3) 现在分词的被动式：一般式现在分词的被动式表示的动作和句中谓语动词表示的动作同时发生；完成式现在分词被动语态表示的动作在谓语动词表示的动作之前发生。例如：The building being built is for the professors of our institute.Not having been te

59、sted, this new-type oil pump cant be put into production.72课堂教学 分词复合结构分词复合结构 分词短语在句中作状语，一般没有自己的主语，句中的主语通常就是分词短语的逻辑主语，但有时分词短语可有自己的主语，有名词或代词表示，放在分词短语之前，他们之间有着逻辑上的主谓关系，这种结构即为分词复合结构，也称为分词独立主格结构。分词复合结构通常在句中作状语，表示时间，原因，条件或伴随情况，附加说明等，也可放在句首或句末，用逗号与句子其他部分隔开。分词复合结构主要有以下形式：73课堂教学1.分词逻辑主语（名词或代词主格）+分词Everything

60、 having been prepared, they began to make a new experiment.The meeting being over, we held a discussion.I having no money, I have to go out to find a job2.由with（或without）+分词逻辑主语+分词这种结构多表示伴随情况或作补充说明，有时也可表示时间，条件，原因等。例如 74课堂教学With night coming on, bats came out.夜幕降临，蝙蝠出来了。 He left the room angrily, without a word more spoken.他愤怒地离开房间，一句话也不再说。3.由There being +主语构成这种结构多表示原因。例如：There being a lot of books to read, he often studied till midnight.因为有许多书要读，他经常学习到深夜。75课堂教学4.分词复合结构的逻辑谓语部分如果是“系表”结构，分词being常常不出现，而仅有表语，常为形容词，副词，名词，介词短语或不定式。例如：The question (being) easy, I got full marks.76课堂教学
