非谓语动词的核心考点
1. 非谓语动词作状语
(1)不定式作状语
①表示目的
He ran so fast as to catch the first bus.
②不定式作结果状语表示出乎意料的结果,动词不定式前常加only。
George hurrieded to the station, only to be told that his train had just left.
③too...to... 结构,too 修饰形容词或副词,不定式表示否定含义。only too...to... 或否定词+too...to... 结构,不定式表示肯定含义。
The box is too heavy for me to carry. 箱子太沉,我搬不动。
I am only too pleased to help you. 能帮助您,我感到十分荣幸!
We are never too old to learn. 活到老,学到老。
④enough to... 结构,enough 后置修饰形容词或副词,意思是“足以……”。
The boy is old enough to go to school. 孩子这么大了,该上学了。
⑤不定式有些约定俗成的说法,可以用作独立状语,主要有:
to tell the truth / to be honest 说实话
to cut a long story short 长话短说
to make matters worse 更糟糕的是
to be sure 可以肯定的是
to be frank 坦率地说
To be honest, the pay isn’t attractive enough.
(2)现在分词作状语
①一般式doing
表示动作和谓语动词同时或几乎同时发生,与句子的主语是主动关系。
Walking in the street, I caught sight of a tailor’s shop. (主动关系)
②完成式having done
表示动作发生在谓语动作之前,与句子主语是主动关系。
Not having completed the programme, they have to stayed there for another two weeks.
③被动式having been done
表示动作发生在谓语动作之前,与句子的主语是被动关系。
Having been asked to work overtime that evening, I missed a wonderful film. (被动意义,非谓语动词的动词的动作发生在谓语动词动作之前)
(3)过去分词作状语
过去分词作状语时,与句子主语之间是被动关系或逻辑上的动宾关系。
Seen from the moon, the earth looks green.
Satisfied with what he did, the teacher praised him in class.
Compared with you, I still have a long way to go.
Explained a hundred times, he still can’t understand it.
The cup fell down to the ground, broken into pieces.
时间状语
原因状语
条件状语
让步状语
结果状语
2. 非谓语动词作定语
(1)现在分词作定语
现在分词主动形式(短语)作定语与所修饰的名词之间存在着逻辑上的主谓关系,表示该动作的主动和进行;现在分词被动形式(补语)作定语与所修饰的名词之间存在着逻辑上的动宾关系,表示该动作的被动和进行。
