Step 1 Introduction 一、动词的 –ing 形式概念 动词的 –ing 形式包括两种: ① 现在分词：具有形容词和副 词特征，可作定语、状 语、表语、宾补 ② 动名词：具有名 词特征，可作主语，宾语，表语， 定语等。 e.g. : There are many sleeping students in class. The lesson is boring. The students feel the lesso n boring. Feeling the lesson is boring, the students are sleepy. 二、时态和语态 Vt. 主动语态 现在 分词 一般式 (与谓语动 词同时发 生) 完成式 (先与谓语 动词之前 发生) doing 被动语态 Being done
Having being done
时态和语态： 1. He hurried home, looking behind as he went. 2. Having finished their work, they had a rest.
3. The large building being built is a library. 4. Having been shown the lab, we were taken to see the library. 三、现在分词的语法功能 1.Attribute e.g.: 1. a running man 2. The man running in the pi cture is Liu Xiang. = The man who is running in the picture is Liu Xiang. 小 结: 1. V-ing 形式作定语可表示主语所作动作正在进行或表 示和所修饰词之间有逻辑主动关系。 2.单个 V-ing 词作定语修饰名词一般置于名词之前 3. V-ing 词组修饰名 词则置于名词之后此时相当于一个 定语从句 Rewrite the following sentences with attributive clauses. The people sitting behind us are teachers =The people who are sitting behind us are soccer players. 2.Predicative e.g.: Your journey in Kenya is really exciting. What you did was disappointing. The nightmare I had last night was very frightening. 现在分词作表语通常表示主语的属性和特征 ,相当于形 容词,含有“令人...",其主语通常是物. 3.Object Complement: e.g.: I heard the girl si nging in the classroom. I noticed a long queue outside the bank waiting for it to open.

I heard her singing a song just now. (正在进行的动作)
2. I he ard her sing a song just now. (听见全过程) Practice: Fill in the blanks with the verb given in its proper form. 1.

All the three boats had sunk in the storm 4.现在分词作状语 1).作时间状语,相当于时间状语从句 (常同连词 when, after, while, once, until 等连用) 注： 当现在分词短语用来表示时间时， 可以和 when,after 等引导的时间状语从句互换 Hearing the bad news, they couldn’t help crying. =When they heard the bad news, they couldn’t help crying. Having received his letter, I decided to write back. =After I had received his letter, I decided to write back. 2).作原因状语，相当于原因状语从句。 Being a student, I must work hard. =Because I am a student, I must work hard.
