standing up against the wall。这是什么句型?为什么会用现在分词?

Question

如题所述

Answer 1

回答：这不是句子，且无上下文，故可以看作现在分词或动名词短语（现在分词和动名词形式一样，都是动词+-ing）。现在分词和动名词的语法功能不尽相同，现讲述如下：
现在分词在句中作表语(相当于形容词)、定语(与所修饰词之间在逻辑上有主谓关系)、宾补、状语(表示时间、原因、伴随、方式、条件、让步等)。如：
The match is very exciting.
I feel the story interesting.
Being ill, he didn't come.
The burning house (相当于The house which is burning) is my uncle's.
动名词在句中作主语、表语（相当于名词，与主语之间是对等关系，可互换位置，意思不变）、宾语、同位语、定语（与所修饰词之间无主谓关系，只表示所修饰词的用途）。如：
Her job is teaching.
Teaching is my job.
I love jogging in the morning.
The reading room (相当于The room for reading) is large.
This is my plan, going abroad for further studies.
