My hometown,( A ) at the fooy of Mouny Tai,is not very moder

答：是：My hometown,which is located at the foot of Mount Tai,is not very modern but it is beautiful.
的另一种表达法,就是用非谓语动词来表示非限制性定语（或状语）表示附加补充信息.
去年which is 剩下的就是located
更深层次思考：locate是及物动词,locate sth.somewhere就是将某物放置在某地.某物与locate在逻辑上是被动关系,得用过去分词,用现在分词,则后面应有一个宾语!
我造一个句子:
The mother,locating her baby in the cradle,is cooking now.
locate =place,put ,lay的意思.
只不过sth.is located in /at/ on .不是被动动作而是一种状态而已.
类似的：Dressed in a white coat,he.
Devote to .,he.
Compared with .,he.
Seated on .,he.
规律：及物动词的过去分词+介词短语,主语.
且这些动词的宾语都为“人”,dress oneself,devote oneself to ...,compare himself with .,seat himself on .

locate 是个及物动词 后边要加宾语的
正常逻辑 应该是 sb locate sth
这句中的 逻辑应该是 locate hometown 反过来不就是 hometown located 过去分词表被动
所以应该用被动

locate 意思是“确定…的位置；确定…地点”，它的用法是 to locate some place，place和locate是动宾关系，如果地点作主语，locate就要用被动语态
located的意思是：位于，一般是地方作主语
在这个句子中，located at the foot of Mount Tai 是过去分词短语作定语，修饰hometown，表示被动。
