结(精选)
一、语法动词不定式与动名词(小结)
动词不定式与动名词都属于非谓语动词。
有些结构中必须用动词不定式,有些结构中必须用动名词,有些结构后面既可以跟不定式,还可以跟动名词,但意义不同。
一)动词不定式
1、什么是动词不定式
动词不定式由to+动词原形构成。
这里的to是不定式标志,没有词义。
不定式的否定结构是在动词不定式前直接加not。
不定式具有名词、形容词或副词的某些语法功能,又有动词的时态和语态的特点及作用。
常见的形式如表所示(以及物动词do为例),不及物动词没有被动语态。
主动语态被动语态
一般式 to do to be done
进行式 to be doing
完成式 to have done to have been done
完成进行式 to have been doing
2、不定式功能及常见不定式
第一类:动词+不定式
语法分析:有些及物动词后面可以用不定式表示动作的对象,这时不定式相当于名词或代词,做及物动词的宾语。
1) want to do sth. 想做某事
