这个答案是哪里用到了非限定性动词啊?
请教一个关于非限定性动词的问题
首先你得了解什么是限定和非限定性动词.
英语动词有限定(finite)和非限定(non-finite)两类.
句子中的谓语动词(predicative verb)是限定的;限定动词受人称(person)和数目(number)的限制.此外,还有时态(tense )、语态(voice)和情态(mood)等.例如:
① Good leaders serve the people whole-heartedly.
② Jason is giving a public lecture.
③ Who did it?
④ I would appreciate it if you could do me a favour.
在句子中可以施展其他功能的动词是非限定动词;这些动词具有一般动词的许多特性,但没有“人称”和“数目”的限制.非限定动词分三种:不定式,分词( the participle); 动名词(the gerund); 分词又分现在分词( the present participle)和过去分词(the past participle).例如:
⑥ Helen has a smiling face.
⑦ Your written English is good.
⑧ Smoking is harmful to health.
⑥里的是现在分词;⑦里的是过去分词; ⑧里的是动名词.
非限定动词及其短语,语法功能庞大,涉及下列五方面:
一 当主语
动名词可当句子的主语,取代名词和代名词.例如:
⑨ Swimming makes us hale and hearty.
二 当补足语
可当主语的句子成分也可当补足语.例如:
● A good government's desire is serving the people.
● What is difficult is to hoodwink the public indefinitely.
同样的,现在分词与过去分词也可充当接系动词(the linking verb)的补足语.例如:
● The witness's evidence is quite convincing.
● At long last,John was fully convinced.
三 当宾语
动名词可充当及物动词的宾语.例如:
● Janet suddenly stopped talking.
它们也可以成为介词的宾语,但除了“except,but,about,than”之外,介词的宾语多数是动名词.
例如:
I am tired of repeating the same point.
四 当名词修饰语
Don't disturb the sleeping dog.(现在分词)
Can you remove the damaged machine?(过去分词)
The sailors came in a fishing boat.(动名词)
五 当动词修饰语
Walking along the road,he came across a friend.(现在分词短语)
Extremely frightened,the picnickers fled.(过去分词短语)
Peter came running.(动名词)
