The butterflies were marked and realeased from Taipei. 句中realeased前面不用再加were. 但是如果把realeased改成flew away,flew away是主動用法，所以它的前面也不用加were。
Louis:那麼如果要表示The butterflies were marked and flew away from Taipei.這句話的意思...正確語法應為何??
: The butterflies were marked and then they were flew away from Taipei.
Toming88:be=have a state or quality where 跟 2 passive voice.by somebody.這2具什麼意思有點不懂

The butterflies were marked and released from Taipei.
＝ The butterflies were marked and (then they were) released from Taipei.
對等連接詞所連結的文字在語法上必是同類的（對應的是兩個過去分詞marked vs released），所以助動詞were只要寫一個。

本句因為未出現by ...，所以動詞的被動意味不強烈。你可以把marked and released from Taipei視為主詞補語（用表示被動的過去分詞當補語）。

The butterflies were marked and then they were flew away from Taipei.
After being marked, the butterlies flew away from Taipei.是正確的寫法。

Having been marked, the butterflies flew away from Taipei.也是正確的寫法．

1. The butterflies were marked and realeased from Taipei. 句中marked and realeased共用助動詞were. 但是如果把realeased改成flew away主動用法，因為有先後順序〈先做記號再飛走，主動與被動無法共用，這是邏輯問題〉。需寫成After having been marked, the butterflies flew away.2. 若無先後順序而是同時發生，就可主動與被動共用。例如：Some protesters were seen setting objects on fire.3. 你的問題頗有創意，向學精神令人欽佩
