常見錯誤
What are common mistakes with "Circulate"?Which "Circulate" sentences look correct but are wrong?
×The news circulated around the city.
✓The news circulated throughout the city.
使用 'around' 暗示物理上的環繞移動，但 'circulate' 更常與 'throughout', 'among', 'within' 連用，表示在群體或範圍內傳播。
×Please circulate this email to everyone.
✓Please circulate this email to everyone. / Please circulate this email.
'circulate' 本身已包含「傳給一群人」的意思，加上 'to everyone' 雖可接受但略顯冗餘。更地道的用法是直接說 'circulate something'。
×Blood is circulated by the heart.
✓Blood circulates through the body. / The heart circulates blood.
在描述血液循環的常態過程時，更常用主動語態 'circulates'。被動語態 'is circulated' 雖文法正確，但較不自然，多用於強調被某物驅動的語境。
×I will circulate the party invitation.
✓I will distribute/pass out/send out the party invitation.
'circulate' 通常用於文件、資訊、消息等在特定群體（如辦公室、會員）中傳閱，不適用於像派對邀請這種一次性發給多人的動作。應使用更具體的動詞如 'distribute'。
×The virus circulates people easily.
✓The virus circulates easily among people. / The virus spreads easily among people.
'circulate' 作為不及物動詞時，主語通常是流通的『物』（如病毒、空氣、消息），不能直接接『人』作為賓語。若要表達在人群中傳播，需使用介系詞 'among'。更常見的動詞是 'spread'。
×He circulated around the room, talking to guests.
✓He moved/walked around the room, talking to guests. / He circulated among the guests.
'circulate' 用於人時，意指在社交場合中與多人交談、周旋，是不及物動詞，後面不接 'around + 地點'。正確用法是 'circulate among + 人群' 或單獨使用。若強調在空間中走動，應用 'move around'。
