动词不定式概述
动词不定式指由to加上动词原形所构成的一种非限定性动词,但在有些情况下to 可省略。动词不定式在语法功能上可作主语、宾语、表语、定语和状语,如:
To ignore this dangerous signal would be a terrible mistake. (作主语)
He promised not to tell anyone else about it. (作宾语)
To treat comrades like enemies is to go over to the side of the enemy.(作表语)
The manager announced his intention to retire.(作定语)
The old man walked slowly on the ice in order not to fall down.(作状语)
不定式中的动词仍然具有动词的特性,可以有自己的宾语和状语,另外虽然动词不定式在语法上没有表面上的主语,但它所表达的意义是动作,这一动作的执行者就是该动词的逻辑主语,动词不定式要和它的逻辑主语在语态和时态上保持一致。
