we've是动词 are moving是动词,这句那个是真正的动词?

你好这个句子的主干属于：
It + is/was + adj./n.(形容词或名词） +to do sth.
即：it 做形式主语,后边的动词是is
“It’s disheartening to see that【后边是一个整体,可以理解为that引导的宾语从句】 we’re losing people that we’ve known our whole lives,are moving to different parts of the country for work,to retire,"
注意,从句也是句子,也有自己的动词
we’re losing people that 【引导定语从句代替people,在从句中做宾语】we’ve known our whole lives,【逗号这里相当于and,是个并列句】are moving to different parts of the country for work,to retire,"
还原给你：We've known [特指提到的人people] our whole lives and [特指提到的人people]are moving to different parts of the country for work,to retire
因此：have known 和 are moving 都是动词哦,是从句中的谓语动词
