答案

看几个例子：
a factory built in 1980= a factory which was built in 1980 (可不能用 is哟）
a factory built by them=a factory which was(也可能是which has been built) by them
a map showing where the village is = a map which shows where the village is (没用is showing哟）
a map hanging on the wall = a map which is hanging on the wall
从上例可看出,不可机械地去套用什么形式.这还得要时态这方面的基础
