past participle 問題

只有004做得比較接近正確，句頭要加being因為are looked after是被動式，改變後仍要維持是被動式的。但是他只是改為present praticiple，所以你是要把主句的tense轉埋做past tense。

Being well looked after, pandas lived longer in the reserve than in the wild.

我同時間把兩次出現的panda化為一個主角,把in the reserve對比in the wide結合來寫。如果擔心改得太多會錯，可以：

Being will looked after, the pandas in the reserve lived longer than the pandas in the wild.

Since the pandas in the reserve had been looked after well, they could live longer than pandas in the wild.

Being well looked after in the reserve, the pandas live longer than pandas in the wild.

這句的past participle是' Since the pandas in the reserve were well looked
after, they lived longer than pandas(或用those代替pandas) in the wild. '

past participle structure:
Well-looked after in the reserve, the pandas live longer than those in the wild.
