Because of air pollution being greatly reduced, this city is still __________.
A. a good place which to be lived in B. lived as a good place
C. a good place to live in D. living in as a good place
答案是C,请问为什么A不对?

答：本题设计得不好.Because of +名词+(定语为分词短语）,因为...的空气污染,（所以）这个城市仍然是一个居住的好地方. 这样的句子有语病!
应改为：As/Because air pollution is greatly reduced, this city is still a good place to live in.
由于（因为）空气污染已经大大减少,（所以说）这所城市仍然是一个居住的好地方.
不过本题的考点不在状语,而在主句中.在主句中a good place后的定语部分.
句型：sth. is +adj. +to +及物动词.比如：sth. is easy to do.=To do sth. is easy.
这里用不定式的主动态表被动.
类似的I have sth. to do .中的to do也是用不定式的主动表被动,在这里是作sth.的后置定语的.
The city is a good place to live in. ==The city is a good place (for us/everyone) to live in.
交流双方（大家）都知道,这不定式的逻辑主语是“人”,是“大家”,所以为了句子的简洁,就用不定式的主动式作后置定语了.
其实,不定式作定语时,其逻辑主语就是被它所修饰的名词（或代词）,你的思维并没有错：place和live in是被动关系.说：The city is still a good place to be lived in (by people) =The city is still a place that is to be lived in (by people).
BD项为凑数项,你能排除,就不去说了.
A项为什么不可以呢?你可能见过介词+which +不定式作后置定语的句式吧?
如：We need more actual facts on which to base our arguments.
本句中的on which to base our arguments就是.=We need more actual facts on which we can base our arguments.=We need more actual facts (which/that) we can base our arguments on.
在定语从句时,介词on可以放在关系代词which前,也可以留在句子后面,但是改用特殊不定式时,则必须是介词+which+to do sth.
为避免一题有两个答案,为避免争议,出题者没有将A中的in放在which的前面.不然,你的：
this city is still a good place in which to be lived . 说不定也是可以的.
