语法精讲
(一)动词不定式
基本形式是“1o+动词原形”,有时也可以不带0。没有人称和数的变化,在句子中不能作
形式
谓语。否定形式是在动词不定式前加not。如:Lily asked me not to use her computer.
作主语:一般位于句首,谓语动词用单数。为了避免句子“头重脚轻”,常用作形式主
语,而把真正的主语(动词不定式)放在句尾。如:It took me half an hour to walk there
作宾语:①及物动词后直接跟带to的不定式。如:I decide to spend the summer in Yunnan.
②“及物动词+疑问词+带to的不定式”结构。如:He told me how to learn English well.
动词不定式
作宾语补足语:常接不定式作宾语补足语的动词有tell,ask,want,teach,order,advise
法
等。如:Mom asks me to sleep early.
作表语:放在系动词之后。如:His dream is to be a teacher.
作定语:放在被修饰词之后。如:Would you like something to eat?
作状语:常作目的状语。如:He raised his voice to be heard clearly,
在使役动词之后,如have,make,let等。
在感官动词之后,如feel,hear,see,watch,notice等。
省略o
的情况
help后的不定式可省略to,也可以带上to。
在其他周定搭配中,如had better do sth.,why not do sth.等。
