for people to live in为什么一定要for people to live in呢?不定式作定语呢?这里又不表示目的,求讲解

to live in 是不定式作定语,for people 是状语.定语不表示目的,只起到修饰名词的作用.状语的功能很多,有表示目的的.这里for people 作方面状语.live只要是居住的意思,都是不及物动词吗?那其他的形式如for people living in为什么不行呢?to live in for people为什么不行呢?,这里面for people to live in是做定语说明place的作用吗?a good place to live in 一个可以住的好地方 (不定式的主动能表示被动)a good place living in 不对,因为living是主动的,这个动作要明确主语是人。to live in for people 也不对,因为for sb. to do sth. 是一个比较固定的结构。a good place for people to live in 一个可以供人住的好地方,不定式说明place的功能或作用。这里面,live没有同源宾语,所以只能是不及物动词吗?那么a good place lived in行不行,也表示被动啊。也就是说主语是this city,他是被住的,所以用被动形式吗?这里面为什么to live in可以主动表被动呢?a good place lived 不行,因为没有we live a good place(我们住一个好地方)这种说法。有we live in a good place 这种说法,但是这个句子无法变为被动句,就是说a good place is lived in by us不符合英语表达习惯。 很多不定式的主动形式都能表示被动的意思,最常见的就是to eat,例如 There is nothing to eat in the fridge.(冰箱里没有什么可吃的。)(made of)aluminum,the machine is very light in weight那么这道题写成the machine which is made of aluminum吗?那么这道题里having made of可不可以选,铁变成铝之后,就变轻了,有先后顺序啊可以写成The machine, which is made of aluminum, is very light in weight.having made of不能选,因为它没有被动的意思。
