The -ing form as the Attributive
02
动名词作定语
动名词作定语,说明它与被修饰语是"目的或用途关系"。
a walking stick
a walking stick
a wafering can
我们可以用for doing或used for doing来置换这个动名词,放在被修饰语之后作定语。
a swimming pool → a pool for swimming → a pool used for swimming
a waiting room →a room for waiting
reading materials →materials for reading
现在分词作定语
说明被修饰语与现在分词是“主谓关系”。现在分词的特征是“主动和进行”,一般可以扩展为一个主动语态的定语从句,从句常用进行时态。单个的现在分词作前置定语,分词短语作后置定语。
单个现在分词作前置定语
a sleeping baby→ a baby who is sleeping
a barking dog→ a dog that is barking
现在分词短语作后置定语
The boy playing football on the playground is my brother.
=The boy who is playing football on the playground is my brother.
在操场上踢足球的男孩是我弟弟。
playing football on the playground
Do you know the girl standing by the school gate
=Do you know the girl who is standing by the school gate
你认识站在学校门口的那个女孩吗
the girl standing by the school gate
who is standing by the school gate
who is playing football on the playground
有时,现在分词不一定表示正在进行的动作。如果现在分词表示习惯意义,如人的国籍、职业、事物的客观存在等,转换为定语从句则用一般时态。
They are visitors coming from several countries.
=They are visitors who come from several countries.
他们是来自几个国家的游客。
coming from several countries
who come from several countries
A young man writing novels came to give us a report yesterday.
=A young man who writes novels came to give us a report yesterday.
一位写小说的青年昨天来向我们作报告。
writing novels
who writes novels
现在分词的被动式作定语
现在分词作定语时,如果被修饰词与其是被动关系,则要用被动式 being done,表示正在被做。
The tall building being built now is our school library.
正在被建的那座高楼是我们学校的图书馆。
The question being discussed was presented by the headmaster.
正在被讨论的问题是校长提出的。
being built
being discussed
在下列情况下,不能用现在分词作定语,应使用定语从句。
(1)如果作定语的动词所表示的动作已经发生,或者与句子谓语动词表示的动作不在同一个时间范围,应使用定语从句,不能用现在分词作定语。
The professor visiting our school yesterday will give us a lecture.
The professor who visited our school yesterday will give us a lecture.
(2)现在分词的完成式,主要用来作状语,表示动作早于谓语动词发生,但不能作定语。
The girl having turned in her paper is Cheryl.
The girl who has turned in her paper is Cheryl
表示情绪变化的现在分词形容词作定语
一些表示令人情绪变化的现在分词表示事物本身的性质及给人的感受,多用来修饰、描写事物,意为"令人……的"。这类形容词是由表示人的心理或情绪变化的"使令性动词"变来的。
The news excites all of us. That is to say , this is exciting news or the news is exciting.
这消息使我们大家很兴奋。也就是说,这是令人兴奋的消息,或者说这消息是令人兴奋的。
excite是一个表示人的心理或情绪变化的"使令性动词",意为"使兴奋;使激动"。
exciting是它的现在分词和形容词,作定语或表语。
amazing, amusing, annoying, astonishing, boring, confusing, convincing,
disappointing, discouraging, disturbing, embarrassing, encouraging,
fascinating, frightening, frustrating, inspiring, interesting, moving,
pleasing, puzzling, pleasing, relaxing, satisfying, striking, shocking,
surprising, tiring, touching, terrifying, worrying等
常见的这类词有
这些分词形容词既可以作定语,也可以作表语,而且都是由相应的“使令性动词”变来。

过去分词表示过去已经完成的动作
the changing world 正在发生变化的世界
the changed world 已经变化了的世界
现在分词作定语,扩展成定语从句是主动语态
The woman standing beside him is his secretary.
→The woman who is standing beside him is his secretary.
过去分词作定语,扩展成定语从句是被动语态

习惯性动作
将要发生的动作

done, being done和to be done,这三种非谓语形式都表示被动,都可以作定语,但它们是有明显区别的。done表示"已经被做",being done表示"正在被做",to be done表示"将要被做"。

她的业余爱好是集邮。
The only way to cure your disease is going to bed.
治疗你的病的唯一办法是睡觉。
collecting stamps
going to bed
现在分词作表语
现在分词作表语,说明该现在分词具备了形容词的作用。它表示句子的主语所具备的某种性质,这个性质是主动的,具备使令意味,让人在情绪上发生变化。
Tom's progress in English is satisfying.
汤姆在英语上的进步是令人满意的。
The story about space travelling is interesting.
那个关于宇宙旅行的故事很有趣。

动名词作表语、现在进行时与现在分词形容词作表语的辨别
Her job is doing the homework.
句1的意思是"她的工作是做作业"。本句中,is是系动
词,looking after the children是动名词短语作表语,
它说明主语的具体内容。主语和表语是对等关系,所
以可以互换位置而意思保持不变:Doing the homework
is her job.
动名词作表语、现在进行时与现在分词形容词作表语的辨别
She is doing the homework.
句2的意思是"她正在照料孩子"。本句中,is是助动词,
looking after the children是现在分词短语,一起构成
进行时态,所以is前后两部分不能互换。不可说:
*Doing the homework is she.
动名词作表语、现在进行时与现在分词形容词作表语的辨别
Her job is very boring.
句3的意思是"她的工作很无聊"。这是现在分词形容词
boring作表语,表明boring具备了形容词的作用,用程
度副词very修饰,说明它已经是形容词了。由于它是由
使令性动词 bore 变化而来,具有主动使令意味。
所以,可以转换为一个主谓宾的句子:
Her job bores her. “她的工作令她厌倦”。
