[其他] 為什麼這個句子不用被動態???

[Butterf1y (Butterfly)]

請問一個句子

during poor growing seasons,

when farmers are only able to produce low-quality crops,

biofuel crops will sell but food crops won't
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

請問為什麼不用被動態呢??????

推 ray289:sell當不及物動詞時可解釋為 to be sell or be on sell
→ ray289:例：Grape are selling high this season. (from AHD)
→ ray289:打錯 to be sold or be on sale 才正確
→ Butterf1y:請問應該解釋為 on sell還是 for sell
推 FULCRUM:will sale是指賣得好的意思吧?
