Basic rules
不定式、动词-ed形式、动词-ing形式都可用作表语,但它们所表示的含义却各不相同。
一、基本概念
什么是表语 从形式上讲,位于系动词后的成分就是表语。从含义上讲,表语是回答主语“是什么”或“怎么样”的语法成分。如:
Albert Einstein is a famous physicist.
阿尔伯特·爱因斯坦是一位著名的物理学家。
原文再现
Every artist's wish is to create something that expresses an idea.
动词不定式作表语有何功能?
动词不定式作表语说明主语的具体内容,表示具体的或将来的动作,还可以表示目的、结果、安排、命令、要求、劝告、意愿等。
当主语是aim,duty,hope,idea,mistake,plan,purpose,suggestion等词或以这些词为中心词的名词词组时,动词不定式作表语表示主语的内容,如:
My work is to clean the room every day.
My chief purpose is to point out the difficulties of the matter.
to create somehing 是动词不定式作表语
工作内容
目标的内容
二、相关语法精讲
以what引导的主语从句,不定式作表语说明主语的内容,如
What I would suggest is to put off the meeting.(建议的内容)
What I'd like to say is to treat the poor creature well. (说话的内容)
Every artist's wish is to create something that expresses an idea.(愿望的内容)
当主语和表语都是不定式时,主语表示条件,表语表示结果,如:
To be kind to the enemy is to be cruel to the people.
To see is to believe.(to see为条件,to believe为结果)
主语表示条件
表语表示结果
动词不定式作表语时to能否省略?
一般情况下,不定式作表语不能省略。
我能做的就是等待。表语表示主语的内容,主语从句中含有do,所以to wait中的to省略
★但如果前面的主语从句中含有do时,可以省略to;如:
All I could do was wait.
★由and或or等连接并列的动词不定式时,第二个(和后面的)不定式可以省略to,如:
My dream is to be an astronaut and explore the universe.
原文再现
动词的-ing form作表语有何功能
动词的-ing form作表语用来说明主语的内容,表示主语的某种性质或状态。当与主语是同一概念的时候,主语与表语的位置可以替换,如:
上面的例句也可以替换为:
Turning to his children's toys is one way for him to find inspiration.
One way for him to find inspiration is turning to his children's toys.
turning to his children's toys在句中作表语,说明主语的内容。
-ing form作表语时句子主语常是表示无生命的事物的名词或what引导的名词性从句。-ing form与主语通常是对等的关系,表示主语的内容,主语、表语可互换位置。如果句中的主语和表语同为动词时,要注意保持两个动词在形式上的一致。如:
Your task is cleaning the windows. 你的任务就是擦窗户。
(Cleaning the windows is your task.)
What I hate most is being laughed at.我最痛恨的就是被别人嘲笑。
(Being laughed at is what I hate most.)
The only thing that interests her is working.她唯一感兴趣的事就是工作。
(Working is the only thing that interests her.)
二者通常可以互换,没有区别;如:
如果一定要区分的话,-ing form表示一般的或抽象的多次行为,to infinitive 表示具体的或一次动作;如:
The most important thing now is to save the boy, whatever it costs.
to infinitive
和-ing form
作表语有什么区别
The most popular pastime is playing chess. 最大众化的消遣是下棋
The most popular pastime is to play chess. 最大众化的消遣是下棋
原文再现
He was particularly interested in the old story about a fish jumping through the “Dragon Gate”.
interested in the old story在句中作表语,表示主语的状态。
动词-ed形式作表语,表示主语的状态。如:
The city is surrounded on three sides by mountains. 这座城市三面环山。
(动词-ed形式作表语)
The library is now closed. 图书馆关门了。(动词-ed形式作表语)
This was a terrible attack and the woman is still very shocked.
这是一次可怕的袭击,这位女士现在仍然很震惊。(动词-ed形式作表语)
动词-ed form作表语和被动语态有何区别?
动词-ed form作表语通常用来描写情景、叙述人或事物的特征及所处的状态,而被动语态强调动作,重点说明动作由谁完成、怎样完成。
试比较以下两个句子∶
(1)The shop is closed now. (动词-ed形式作表语,说明商店的状态)
(2)It was closed by the manager. (被动语态,强调动作)
此外,动词-ed形式作表语时,在功能上更接近形容词,它不仅可以用于be之后,也可根据需要用于其他系动词(如seem, appear)之后,而被动语态中的过去分词动作意味较强,它只能与助动词be(有时可能是get)构成被动结构,不能用于其他动词之后。
表示“使……”意义的动词的-ed form和-ing form作表语
amaze 使惊讶
astonish 使惊奇
bore 使厌倦
confuse 使迷惑
disappoint 使失望
delight 使高兴
discourage 使气馁
excite 使兴奋
encourage 使鼓舞
exhaust 使疲倦
inspire 激励
move使激动
please使高兴
puzzle使不解
satisfy使满意
surprise使吃惊
shock使震惊
tire使疲惫
upset 使恼怒
frighten 使恐惧
interest 使感兴趣
这类动词通常称为
半使役类动词
半使役类动词的-ing form和 -ed form的用法区别,-ing form修饰事物,描述事物的特征,-ed form修饰人或人的表情、心理活动等;如:
The film we saw last night was very interesting. 我们昨天晚上看的电影非常有趣。
We were all interested in the film. 我们都对这部电影感兴趣。
The frightening hurricane made the girl very frightened.
令人恐惧的飓风使这个女孩感到害怕。
