动词不定式的简介
动词不定式是由to+动词原形组成,是动词的非谓语形式。它可以带宾语,构成动词不定式短语,在句中起名词、形容词和副词的作用,因此在句中可以充当谓语以外的任何成分,即主语、表语、宾语、定语、状语、宾补、主补和同位语。
一、动词不定式的语法功能
(1)动词不定式(短语)作主语
To love is to be loved. 爱别人就是被人爱
To teach is to give. 教育就是奉献
※注意:
1)在口语中,动词不定式作主语时常用it做形式主语,而真正的主语则被置于句子的后面。
It will takes me three hours to do this job.
It is of great importance to solve the housing problem.
动词不定式做主语
2)假如动词不定式要带逻辑主语。则需介词of或for来引导。
It is good for me to have a talk with you.
It is cruel of man to kill animals in such a casual manner.
总结:能用于介词of的结构的形容词有:good, kind, bad ,wicked,clever,wise,foolish,stupid,selfless ——主观感情或态度
能用于介词for的结构的形容词有:important,necessary,impossible,better——客观情况
3)在疑问句或感叹句中要用it来做主语
例如:Is it worth our while to hold such a long meeting?
What good news it is for me to hear that my brother has got his visa to America!
(2)动词不定式作宾语
She decided to quit her job at last.
I hope to see you soon.
