第一次發問

煩請高手回答一下囉

關於分詞構句的

1.As he was idle in his youth, he has to work hard in his old age.

=Having been idle in his youth, he has to work hard in his old age.
~~~~~~~~

我的問題是 去掉連接詞As 和相同的主詞he 任何動詞改現在分詞

那為何會出現having勒? 應該是由was變為being 然後省略掉being不是嗎?


2.(改錯) Comparing with his brother, he is not so intelligent.
~~~~~~~~~~~

~~~~~部分要改為compared 這是為什麼呀?

謝謝!!
