关于WHO引导的重句

看以下下面解释：
有时为了简洁起见可将定语从句转化为分词短语作定语：

Who’s the girl who is sitting beside Jim? / Who’s the girl sitting beside Jim? 坐在吉姆旁边的女孩是谁？

Most of the people who were invited to the party were teachers. / Most of the people invited to the party were teachers. 应邀参加晚会大多数是教师。

Anyone who touches that wire will get a shock. / Anyone touching that wire will get a shock.任何人触到那根电线都会遭到电击。

注意，并非所有的定语从句都能转换成分词短语，比如那些不能后置定语的分词短语就不能与定语从句进行转换：

误：This is the boy being from the country. (being引出的分词短语通常不用定语，除非它是构成被动语态的助动词)

正：This is the boy who is from the country. 这是来自乡下的那个男孩。

误：We caught the thief having stolen the car. (现在分词完成式不用作定语，即使换成一般式也不对，因为现在分词短语作定语时它不能先于谓语动作之前发生)

正：We caught the thief having stolen the car. 我们抓住了偷汽车的小偷。

没有省略吧，那个是定语从句，修饰the people 的，若加上who，是要在living前加上are的

这个不是从句啊，动名词living做people的宾补，这个句子是个名词性的句子成分，后面的是状语
