我今天考了 不是這个考古:一種動物還是烏模仿人說話的問題。
某種鳥唱duet with her partner, when other lone female is around and other lone male is around than when other female accompany with male partner. 某專家說 This is to indicate how female bird try to protect security over her partnership.
Ask: When does this female bird sing duet? A. When other female lone bird around, than other male lone bird aound, than other female with family. B. When other female lone bird or other male bird around than other females with families. 大概這樣 |
