《Section B》语法解析
动词不定式作宾语
动词不定式是一种非谓语动词形式,其结构为 “to+动词原形”,其中to不是介词,而是动词不定式的符号,称为小品词。动词不定式没有人称和数的变化,在句子中可以作主语、表语、宾语、补足语、定语或状语等。今天我们重点学习后接动词不定式作宾语的常见动词(短语)。
用法:want,hope,decide,agree,choose,would like,plan,fail等动词(短语)后接动词不定式作宾语
例句:I decided to go to the countryside for vacation. 我决定去农村度假。

like,love,begin,start等动词后既可以接动词不定式,也可以接动名词形式,意义上差别不大
“find/think/feel+it+形容词+动词不定式”结构,其中it为形式宾语,动词不定式为真正的宾语
例句:Please teach me how to play the piano. 请教我怎么弹钢琴。
