问题描述：
Guilin is one of the tourist attractions famous both at home and abroad
为什么直接famous?
答
很高兴为你解答.
保证正确率~!
【解析】：
Guilin is one of the tourist attractions famous both at home and abroad.
桂林是国内外都著名的旅游景点之一.
这里的 famous both at home and abroad 是形容词短语做后置定语.等于：
Guilin is one of the tourist attractions 【 that are】 famous both at home and abroad.
形容词短语作定语都需要后置,单个的形容词作定语一般前置（除了修饰enough等的特殊情况）.
祝开心~!为什么可以省略are不是省略 are ，是省略 that are，这里是形容词短语做后置定语。单独的 are，句子不就有两个谓语了？
