2、结非谓语动词中的现在分词主要起形容词和副词的作用，在句中作定语、表语、补语或状语。现在分词有两个基本特点。1.时间上表示动作正在进行。例如:a developing country一个发展中的国家/rising sun 冉冉升起的太阳（试比较:a developed country一个发达国家/risen sun 升起的太阳）2.时态上表示主动。例如:the ruling class 统治阶级/the exploiting class 剥削阶级。（试比较:the ruled class 被统治阶级/the exploited class 被剥削阶级）具体用法总结如下:(1)作定语单个分词作定语
3、时放在所修饰名词前，分词短语作定语时放在后，The sleeping boy is my son.They went along the path leading to the mountain top.并且名词与现在分词之间存有逻辑上的主谓关系，On hearing the news of his fathers death, he burst into tears.(2)作补语高中阶段只研究分词作宾补的情况，不研究作主补的情况。只有两类动词可以加现在分词作宾补:感官动词:see,hear,watch,feel,notice,observe,keep,find,listen to,look
4、at使役动词: have,get,catch,leave,set值得注意的是要想用现在分词来作宾补，只能是用于这些词后，但是并不代表这些动词后的宾补形式都要用现在分词（有些后面可以加不带to的不定式作宾补）。例如:I saw him singing now.Dont have the students studying all day.注意:宾语与作宾补的现在分词之间存在逻辑上的主谓关系，即宾语是现在分词动作的发出者。至于现在分词作主语补足语的情况，只需知道上述动词的被动语态形式中的现在分词作的是主补即可，无须深入。（3）作表语现在分词作表语有三级变化，可被副词修饰。例如:The story
5、is interesting./The match is exciting.（4）作状语作时间、条件、原因以及让步状语时要位于句首，且与后面用逗号隔开，能转换为一个相应的状语从句。作结果、方式及伴随状语时要位于句尾，且与前面用逗号隔开，有时也可以不用。注意分词作状语时的逻辑主语（即分词动作的发出者）一般要与句中主语保持一致。(这个是重点，也是考试和高考的常考点，必须记住。)作时间状语。例如:Walking in the street,I saw him.（=When/While I was walking in the street,I saw him.）Having received his
6、 letter，I decided to write back作条件状语。例如:Working hard, you will succeed. =If you work hard, you will succeed. 作原因状语。例如:Being ill, she stayed at home.（注意：being是常用来作原因状语的）Having been to the Great Wall many times，he didnt go last week. =Because (As) he had been to the Great Wall many times，he didnt go l
7、ast week. 作让步状语。-ing短语作让步状语，可置于句首或 句末，常与even if, though 连用。如：例如:Having failed many times,he didnt lost heart.Though working from morning till night, his father didnt get enough food.=Although his father worked from morning till night, he didnt get enough food. 虽然他父亲从早到晚拼命地干活，但是他还是挣不到足够的吃的。作结果状语。例如:H
8、is friend died, leaving him a lot of money.作方式状语。例如:Please answer the question using another way.作伴随状语。例如：He is standing there, singing.They came into the classroom, singing and laughing. （5）作独立成分。例如:generally speaking（一般来说）， frankly speaking坦白的说，judging from/by （由判断出）， considering考虑到Seeing that因为合作
9、探究 携手共进Successful experiences only contribute to more exploration for successes. 现在分词的否定式：现在分词的否定式中，否定词not 必须放在最前面。Not knowing much English,he found it difficult to communicate with foreigners.Not having received a reply,he wrote a letter to the professor again.现在分词的时态：（1）现在分词的一般式表示动作与谓语动词的动作同时发生。Se
10、eing the teacher is coming, the students stopped talking.(2)现在分词的完成时所表示的动作发生在谓语动词的动作之前。Having lived in the United State for many years, my brother knows a lot about the American culture.现在分词的语态：being done/ having been doneAS the lecture being given is of great importance, the students are listening
11、very carefully. Having been discussed several times, the decision was finally made.小结： 1. -ing短语与when, while, though, until, if等连词连用时，相当于这些连引导的一个从句。如：While staying in Beijing, he came to see me twice.=While he was staying in Beijing, he came to see me twice.Though willing to attend the party, he ref
12、used the invitation. =Though he was willing to attend the party, he refused the invitation.2. 动词-ing形式在句中作状语时，其逻辑主语与主句的主语保持一致。Hearing the news, he burst into tears.练一练：Choose the correct sentence.1. a.
