分词引导的状语从句

由分词引导的状语从句
Having had lunch,he had a cup of tea.关于这个句子有什么见解.对于这样的我不怎么明白,前面的分词怎么解释

Answer 1

我觉得是
have had 即 have done 是现在完成时
have had 的现在分词形式 having had 引导 lunch,做伴随状语，
表示一个主语做两件事，主语两个he，省略一个he
He have had lunch,he had a cup of tea
他吃完了饭，他喝了杯茶
Having had lunch,he had a cup of tea
吃完了饭，他喝了杯茶
He have had lunch,having a cup of tea
他吃完了饭，喝了杯茶
这三句，每句都分成两句看，he是主语，
have done 和 had 和 have 分别是谓语，
lunch和tea是宾语，
a cup of 是限定词，限定tea
因为一个句子成分主谓宾齐全了，不能有两个谓语，又要把两句话一起说
所以省略一个主语，变换谓语动词的形式，即变成doing引导的伴随状语

Answer 2

可以认为是(while he was) having had lunch,he had a cup of tea所有类似的句子都可以理解成 在分词之前有个when 或者while
