被動語態不是反派：什麼時候該用，什麼時候該停

被動語態不是反派：什麼時候該用，什麼時候該停

"Mistakes were made" 很像有人一邊倒退一邊離開房間的句子版本。誰犯了錯？印表機？行事曆？一張可疑的試算表？被動語態名聲不太好，因為它可以把負責的人藏起來。但被動語態不一定有問題。有時候它正是最適合的工具。

訣竅不是「永遠不要用被動語態」。這個建議太簡化了。更好的問題是：讀者應該把焦點放在執行動作的人，還是承受動作的事物？

Quick Answer

主動語態把執行者放前面：

  • The team fixed the error.
  • A storm damaged the roof.
  • The manager approved the request.

被動語態把承受者放前面：

  • The error was fixed by the team.
  • The roof was damaged by a storm.
  • The request was approved.

當承受動作的事物比執行者更重要，或執行者未知、明顯、不重要，或句子需要更正式、更重視流程的語氣時，可以用被動語態。當它會隱藏責任、讓句子變笨重，或削弱清楚的動作時，就應避免。

The Pattern

被動語態由 be + past participle 組成：

  • is written
  • was built
  • were chosen
  • has been approved
  • will be delivered

時態放在 be 動詞裡。主要動作變成過去分詞。

Tense Active Passive
Present simple They review the file. The file is reviewed.
Past simple They reviewed the file. The file was reviewed.
Present perfect They have reviewed the file. The file has been reviewed.
Future They will review the file. The file will be reviewed.

如果執行者重要，可以加上 by + doer：

  • The song was written by two friends.
  • The bridge was designed by a local architect.

但很多被動句會省略執行者，因為那不是重點：

  • The package was delivered this morning.
  • The road is closed for repairs.
  • The results will be announced tomorrow.

Natural Examples

When the Receiver Matters More

  • The museum was opened in 1924.
  • The tickets were sold out in ten minutes.
  • The proposal was rejected after the budget review.

在這些句子裡，museum、tickets 和 proposal 才是主角。執行者可能已知，但它不是最有用的句首資訊。

When the Doer Is Unknown

  • My bike was stolen.
  • The window was broken during the night.
  • The file was deleted by accident.

如果你不知道是誰做的，被動語態能避免硬編一個主詞。

When the Doer Is Obvious

  • The patient was taken to the hospital.
  • The suspect was arrested at the airport.
  • The exam papers were collected at the end.

執行者從情境就很容易猜到。除非那些細節重要，否則不需要說 "by the medical team"、"by the police" 或 "by the teacher"。

When the Tone Is Formal or Process-Focused

  • Applications must be submitted by Friday.
  • All devices should be turned off before takeoff.
  • The data was analyzed using the same method.

被動語態常見於指示、政策、學術寫作、報告和公告，因為流程通常比人更重要。

When It Improves Flow

被動語態也能讓段落順著舊資訊移動到新資訊。英文讀者通常喜歡句子從已經提過的東西開始，再加入下一個資訊。

  • We found a crack in the wall. The crack was repaired the next morning.

你也可以寫 "A contractor repaired the crack the next morning"，如果 contractor 很重要，這完全沒問題。但如果段落在談 crack，被動語態會讓聚光燈留在同一個位置。

報告裡也常見這種情況：

  • The survey included 600 responses. The responses were grouped by age and study goal.

第二句從 responses 接下去，而不是從那個未知的整理者開始。這不是軟弱的寫法，而是有組織的寫法。

When Active and Passive Both Work

有時候兩個版本文法都正確，但會引導讀者注意不同地方。

  • Active: The city council approved the new bike lanes.
  • Passive: The new bike lanes were approved by the city council.

如果段落在談 city council 的決策，主動句比較好。如果段落在談 bike lanes 發生了什麼事，被動句比較好。選擇前先問：這段文字正在追蹤什麼？行動者、動作，還是結果？

這個問題在長篇寫作中特別有用。一個句子單獨看可以很清楚，但如果它把聚光燈打錯方向，在段落裡仍然會不順。

Common Traps

Trap 1: Hiding Responsibility

"The deadline was missed" 文法上可能正確，但如果責任很重要，聽起來會像在閃躲。"We missed the deadline" 更清楚，也更直接。

被動語態可以禮貌，但也可能變成霧。如果讀者需要知道誰做了事，就說出誰做了事。

Trap 2: Making Easy Sentences Heavy

"The sandwich was eaten by Sam" 是正確的，但 "Sam ate the sandwich" 更俐落。被動語態要值得它佔的位置。如果主動版本更短且同樣清楚，選主動。

Trap 3: Confusing Passive Voice With Past Tense

不是每個有 was 的句子都是被動。

  • She was tired. 這不是被動。
  • The meeting was long. 這不是被動。
  • The report was written yesterday. 這是被動。

找 be + past participle，以及主詞是否承受一個動作。

Trap 4: Forgetting Agreement

be 動詞必須和主詞一致：

  • The file was updated.
  • The files were updated.
  • The information was updated.

不要被動詞後面的名詞分心。控制動詞的是主詞。

Trap 5: Adding By When It Does Not Help

"The forms were submitted by applicants" 往往比 "Applicants submitted the forms" 弱。如果執行者是一個一般群體，而且動作很簡單，主動語態可能更自然。

Trap 6: Using Passive Voice to Sound Serious

被動語態可以聽起來正式，但正式不等於更好。"The notes were reviewed and the plan was discussed" 可能正確，但如果作者可以說 we，"We reviewed the notes and discussed the plan" 更清楚。不要只是因為句子感覺更官方就選被動。要因為焦點放對了才選。

Wrong / Better / Why

Weak or Wrong Better Why
The decision was made by the committee after three meetings. The committee made the decision after three meetings. 執行者重要，而且主動語態更俐落。
The phone was stole. The phone was stolen. 被動語態需要過去分詞。
The files was uploaded. The files were uploaded. be 動詞要配合複數主詞。
Mistakes were made in the report. We made mistakes in the report. 如果責任重要，就說出執行者。
The road workers repaired the road, and the road was reopened by them. The road workers repaired the road and reopened it. 重複被動讓句子變笨重。
The tickets sold out quickly by the fans. The tickets were bought quickly by fans. 這裡 sold out 常是不及物用法；被動形式需要真正的及物動作。

Mini Practice

判斷每句應該保留被動，還是改成主動。需要時請改寫。

  1. The roof was damaged by heavy rain.
  2. The report was finished by Maya at midnight.
  3. The password was changed yesterday.
  4. The new policy was announced by the company.
  5. The cookies were eaten by my brother.
  6. The museum was built in 1890.
  7. The invoice was not sent on time.
  8. The coach selected three new players.

Answer Key

  1. 被動可以。焦點是 roof，而且原因重要。
  2. 主動可能更好：Maya finished the report at midnight.
  3. 如果執行者未知或不重要，被動可以。
  4. 兩種都可以。政策是焦點就用被動；公司是焦點就用主動。
  5. 主動更俐落：My brother ate the cookies.
  6. 被動很自然。焦點是 museum。
  7. 被動可能聽起來像在閃躲。如果執行者重要，可以說：We did not send the invoice on time.
  8. 主動已經很清楚。保留。

Tiny Summary

被動語態是 be + past participle。

當承受者、結果或流程最重要時使用。

當它隱藏責任或讓簡單句變笨重時避免。

直接動作通常用主動語態更清楚。

被動語態不是反派。它是一個工具。要有意識地使用。
