What is
non-predicate verb
动词的两个基本用法:谓语(形式多样化)和非谓语
非谓语动词—定义
在句中充当除谓语以外的句子成分的动词形式叫做非谓语动词。(简单来说,除了不作谓语,其它句子成分都可以用非谓语动词表示)。
为什么会有非谓语动词存在—功能
一个句子有且只能有一个动词作谓语。
(其他动词要在该句子中存在只能变成非谓语)。
非谓语动词的三种基本形式:
to do(不定式), doing(现在分词 / 动名词), done(过去分词)
不定式 (to do): 表示目的、未来或将发生的动作。
动名词/现在分词 (doing):表示主动、进行或习惯性动作。
过去分词 (done): 表示被动或已完成的状态。
Step1:判断是否需要用非谓语动词
1.一个简单句有且只能有一个谓语动词:
He plays football every day.
2.若句中出现两个及以上的动词,需用连词把它们连接起来:
He is a player and plays football every day.
3.复合句 (从句)中,有几个简单句就有几个谓语动词:
He is a player who plays football every day.
非谓语动词→做题技巧
Step1:判断是否需要用非谓语动词
如果一个句子中已经存在一个谓语动单词,在没有连词,也不是复合句的情况下,那么第二个动词就用非谓语动词。
I don 't know the woman talking to my mother.
句中已经有了谓语动词know,并且没有连词,也不是复合句,那么出现的第二个动词talk就得用非谓语形式。
_____many times , but he still couldn't understand it .
2. _____many times , he still couldn't understand it .
A. Having been told B. Telling
C. He was told D. To tell
C
A
Step2: 判断是主动还是被动
①找非谓语动词的逻辑主语:
②判断非谓语动词和逻辑主语之间是主谓(主动)关系还是动宾(被动)关系.
______from space , the earth looks blue .
2.____from space , we can see the earth is blue .
A. Seen B. Seeing C. To see D. See
A
B
非谓语动词虽不能作谓语,但仍具有动词特点,其逻辑上的动作执行者就叫做逻辑主语。
I like ______ (play) the piano.
He likes ______ (play) the piano.
They like ______ (play) the piano.
playing
playing
playing
The differences between predicate and non finite verb
非谓语动词(Non-finite Verbs)是动词的非限定形式,不随主语人称、数及时态变化。 非谓语动词不受主句时态影响,但存在自身时态形式以体现动作时间关系。
非谓语动词的时态、语态
非谓语 时态 主动 被动
to do 一般式 to do to be done
完成式 to have done to have been done
进行式 to be doing /
doing 一般式 doing being done
完成式 having done having been done
done 一般式 / done
Step3: 判断时态
非谓语动词(不定式、动名词、分词)的时态并非独立存在,而是通过其与句子谓语动词的时间关系来体现。核心判断标准为: 非谓语动作与谓语动作发生的先后顺序 ,具体可分为三种情况:
1.完成式 :表示动作发生于谓语动作之前。
例: Having finished homework, he went out.(现在分词完成式表前置动作)。
____ our homework, we went out to play basketball.
A. Finish B. Finished
C. we finished D. Having finished
D
Step3: 判断时态
2.一般式 :表示与谓语动作同时或之后发生。
例:She seems to understand the problem.(不定式一般式表将来动作)
Seeing the accident, she called 120 immediately.(seeing与called同时发生).
3.进行式 :强调动作正在进行。
例: Being repaired , the road caused traffic jams.(现在分词被动进行式)。
Step3: 判断时态
The building ______now is a restaurant .
2.The building ______next year will be a restaurant .
3.The building ______last year is a restaurant.
A. having been built B. to be built
C. being built D. built
C
B
D
句1中 now 说明大楼正在被修,故用进行式,选C。
句2中next year 说明大楼将在明年被修,故用表将来的不定式,选B。
句3中 last year 说明大楼已被修,但不能选A,因为现在分词的完成式不能作定语,故用过去分词, 选D

Summary
实战技巧口诀
· 作主语/宾语:“一件事”用doing,“目的未来”用to do。
· 作定语:“被动完成”用ed,“主动进行”用ing,“将来目的”用to do。
· 作状语:分析主语定主动,主被关系是关键。主动用ing,被动用ed,目的用to do。
· 作补语:看感觉和使役,主动进行用ing,被动完成用ed,省略to要牢记。

句子分析
1.Walking along the beach. she found a beautiful seashell.
她沿着海滩走着时,发现了一个美丽的贝壳。
(walk是非谓语,和谓语动作find同时发生,且和逻辑主语 she是主动关系,所以用现在分词)
2. To succeed in life. one must be persistent and hard-working.
要在生活中取得成功,一个人必须坚持不懈、努力工作。
(succeed是非谓语,和逻辑主语one是主动关系,还没有成功,所以用不定式表将来)
3. Having been invited to the party,my brother was very happy
(invite是非谓语,发生在谓语动作behappy之前,且和逻辑主语my brother是被动关系,所以用完成被动式)
