these are pictures of people working.句型

问题描述:

these are pictures of people working.句型
these are pictures of people working.
这句话中people working是什么成份,可否写成working people
working应该是现在分词短语做people的定语,不知道写成working people对不?

people 是做介词of的宾语
working是做people的后置定语
不可写成working people
work当工作讲,为vi
当解决讲,为vt 比如 work out math problem
