Answer:這里"tired" 雖然形似過去分詞,但做的卻是形容詞.
Tired of sleeping on the floor,a young man in Teheran saved up for years to buy a real bed.
可轉(zhuǎn)化為:
A young man in Teheran saved up for years to buy a real bed because
he was tired of sleeping on the floor.
可以看出:be tired of ...厭煩...
如果是過去分詞那么就表被動,可這里顯然不是,所以當(dāng)簡化成非謂語形式做原因狀語時只能理解成" being tired of "
補充問題回復(fù)：
surprised by his words,
這里surprised 是過去分詞 (非謂語形式的過去分詞本身表被動,這是為什么上面LZ所例句不能單純的把"tired"看成是過去分詞的原因)
還原成狀語為：
As I was surprised by his words.
因為他的話讓我感到吃驚.
