Fooled是過分也是動片,由Don' t be fooled by nature簡化,fooled被by nature副詞修飾或當形容詞修飾, He is good by nature, good是形容詞被 by nature 副詞修,fooled算形容詞或動片?

Don't be fooled by his appearance.
這裡的主要動詞是fool，be fooled是其被動態（前面的do be都是助動詞）。介系詞片語by his appearance是其形式上的「修飾語」，功能在帶出動詞原來在邏輯上的主詞。
Tim was fooled into believing that he'd won a lot of money.受害人比較重要，故使用被動態動詞。
Don't be fooled by nature.是同樣的道理。

He is good by nature.
介系詞片語by nature修飾的對象是「述部」is good。屬副詞性質。

fooled 是被動詞，即是被整到的.....................
