S: 老师,be full of 作后置定语时,就没有be动词了？为什么？比如：
His face full of confidence looks much younger .
T: 此句来源于主系表结构的定语从句的简化：
【形容词短语作后置定语 prep】His face which is full of confidence looks much younger.=
His face (being) full of confidence looks much younger.
S: 定语从句可以简化成分词短语作后置定语，若定从是主系表句型，简化后，现在分词being可省，就成了形容词短语作后置定语。

T: 分析得很好！
所以结论是：形容词短语做后置定语，就是主系表(adj.)结构的定语从句的简化（定语从句可以是限制性或非限制性的，且句中表语为形容词。）
总结一下：
