副詞子句英文(Adverb Clause)全攻略:定義、分類、用法與減縮子句詳解

什麼是副詞子句?為什麼掌握副詞子句是提升英文寫作與口說能力的關鍵?副詞子句(Adverb Clause)是英文文法中用於修飾動詞、形容詞或整個句子的從屬子句,透過when、because、if、although等連接詞,為句子增添時間、原因、條件、讓步等多層次的邏輯關係。無論你是準備多益(TOEIC)、雅思(IELTS)等英文檢定,或是在職場、學術領域需要精準表達複雜概念,熟練運用副詞子句都能讓你的英文表達更加專業流暢。

然而,許多學習者在使用副詞子句時常犯下時態錯誤、標點符號誤用、或混淆三大從屬子句的問題。特別是「時間與條件子句必須用現在式代替未來式」這條規則,即使是中高階學習者也經常忽略。PREPEDU深入分析英文學習者的常見盲點,為你整理出九大類副詞子句的完整用法、30組實戰練習題,以及分詞構句簡化技巧,助你系統化掌握這項核心文法,在考試與實務溝通中展現卓越的英文實力。

I. 什麼是副詞子句英文?定義與核心概念

副詞子句(Adverb Clause 或 Adverbial Clause)是一種從屬子句(Dependent Clause),其功能如同副詞一般,用於修飾句中的動詞形容詞或另一個副詞,為句子增添時間、地點、原因、條件、目的、結果、讓步、方式或比較等額外資訊。

結構公式

從屬連接詞 + 主詞 + 動詞(+ 其他成分)

 

例如:

  • When the sun rises,birds start singing.(當太陽升起時,鳥兒開始歌唱。)

  • She studied hard because she wanted to pass the exam.(她努力讀書,因為她想通過考試。)

  • I will wait until you arrive.(我會等到你抵達。)

副詞子句本身無法獨立存在,必須依附於主要子句(Independent Clause 或 Main Clause)才能構成完整句意。這種從屬性質使它成為複句(Complex Sentence)的重要組成元素,讓句子表達更具深度與邏輯性。在英文寫作中,熟練運用副詞子句能讓你的文章結構更加緊密,邏輯關係更加清晰,是從中階邁向高階英文能力的關鍵指標。

錯誤範例 ❌

說明

句首

主要子句前必須加逗號

Although it was raining heavily in Kaohsiung, we went hiking in the mountains.(雖然高雄下著大雨,我們還是去山上健行。)

Although it was raining heavily in Kaohsiung we went hiking in the mountains.

副詞子句置於句首時,需以逗號與主要子句區隔,這是正式寫作的基本規範

句尾

主要子句後不加逗號

We went hiking in the mountains although it was raining heavily in Kaohsiung.(我們去山上健行,儘管高雄下著大雨。)

We went hiking in the mountains, although it was raining heavily in Kaohsiung.

句尾副詞子句通常不需逗號;非正式口語可見,但正式寫作應避免

句中(較少見)

前後皆需加逗號

The project, when completed next month, will benefit many communities in Taiwan.(這個專案在下個月完成時,將會造福台灣許多社區。)

The project when completed next month will benefit many communities in Taiwan.

插入句中的副詞子句屬補充說明,需用成對逗號標示

這個「句首加逗號、句尾不加逗號」的原則是副詞子句用法中最重要的標點規範,務必牢記並在寫作中正確應用。掌握這個規則,能讓你在托福(TOEFL)、雅思(IELTS)或多益(TOEIC)等英文檢定的寫作部分取得更高分數。

IV. 重要注意事項:時態陷阱與特殊結構

在使用副詞子句時,最容易犯錯的地方就是英文時態的選擇,特別是在「時間副詞子句」與「條件副詞子句」中。英文有一條絕對規則必須遵守:用現在式代替未來式。這個規則是英文學習者最常忽略,卻也是考試中最常被測試的重點之一。

當副詞子句表達未來的時間或條件時,子句內必須使用現在式,而非未來式,即使主要子句使用未來式亦然。這條規則適用於所有時間連接詞(when、before、after、as soon as、until 等)與條件連接詞(if、unless、as long as 等)。

類型

正確句(現在式)

錯誤句(未來式)

錯誤原因說明

時間副詞子句(when)

✅ When he arrives at the Songshan Airport tomorrow, we will start the meeting.(當他明天抵達松山機場時,我們就會開始會議。)

❌ When he will arrive at the Songshan Airport tomorrow, we will start the meeting.

時間副詞子句不可使用未來式

條件副詞子句(if)

✅ If it rains in Taipei next weekend, I will stay home and finish the report.(如果下週末台北下雨,我就會待在家完成報告。)

❌ If it will rain in Taipei next weekend, I will stay home and finish the report.

條件副詞子句不可使用未來式

時間副詞子句(before)

✅ Before Xiaowang leaves for the Xianggang business trip, he must submit all pending documents.(在小王動身前往香港出差之前,他必須提交所有待處理的文件。)

❌ Before Xiaowang will leave for the Xianggang business trip, he must submit all pending documents.

時間副詞子句不可使用未來式

時間副詞子句(as soon as)

✅ As soon as the quarterly results are published, the stock price will react immediately.(季度業績一公布,股價就會立即反應。)

❌ As soon as the quarterly results will be published, the stock price will react immediately.

時間副詞子句不可使用未來式

條件副詞子句(unless)

✅ Unless the company implements cost-cutting measures, profitability will continue to decline.(除非公司實施削減成本措施,否則獲利能力將持續下降。)

❌ Unless the company will implement cost-cutting measures, profitability will continue to decline.

條件副詞子句不可使用未來式

例外情況:名詞子句可以使用未來式

當 when 或 if 引導的是名詞子句而非副詞子句時,可以使用未來式。這是許多學習者感到困惑的地方,關鍵在於判斷子句的功能。

名詞子句範例(可用未來式)

副詞子句範例(必須用現在式)

  • I don't know when he will arrive.(我不知道他什麼時候會到達。)——名詞子句,作為 know 的受詞

  • Please tell me if you will attend the meeting.(請告訴我你是否會參加會議。)——名詞子句,作為 tell 的受詞

  • The question is whether Xiaowang will accept the promotion.(問題是小王是否會接受升遷。)——名詞子句,作為補語

  • When he arrives,we will start.(當他到達時,我們就會開始。)——副詞子句,修飾動詞 will start

  • Call me if you need help.(如果你需要幫助就打給我。)——副詞子句,修飾動詞 call

區分方法:若子句可被 something、the time、the fact 等名詞取代,即為名詞子句,可用未來式;若子句修飾動詞,即為副詞子句,須用現在式。

其他時態使用注意事項

使用情境

時態用法說明

英文例句

過去時間的副詞子句

描述過去已發生的事件時,副詞子句與主要子句皆正常使用過去式

When I visited Taipei last month,I stayed at a hotel near Xinyi District.(當我上個月造訪台北時,我住在信義區附近的飯店。)

完成式(強調已完成)

當要強調某動作在另一動作之前已完成時,使用現在完成式或未來完成式

After she has finished the project,she will take a week off.(她完成專案後就會休假一週。)

完成式(By the time)

表示在某時間點之前已完成的動作,常搭配完成式使用

By the time you arrive,I will have prepared everything.(到你抵達的時候,我會已經準備好一切。)

持續性動作

當強調動作在一段時間內持續進行時,使用進行式

While I was working on the report,my phone kept ringing.(當我在處理報告時,我的電話一直響。)

這條時態規則是副詞子句中最重要也最容易犯錯的地方,在多益(TOEIC)、托福(TOEFL)、雅思(IELTS)等英文檢定考試中頻繁出現,務必牢記並在寫作與口說中正確應用。

V. 進階:副詞子句的簡化(減縮子句與分詞構句)

當副詞子句與主要子句的主詞相同時,可將副詞子句簡化為分詞構句(Participial Phrase 或 Reduced Adverb Clause),使句子更簡潔流暢。這是進階文法技巧,掌握後能大幅提升寫作品質,讓你的英文表達更加精煉專業。在學術寫作、商業報告與正式文件中,分詞構句的使用頻率很高,是展現高階英文能力的重要指標。

簡化三步驟公式

  1. 確認主詞動詞一致性:副詞子句與主要子句的主詞必須相同

  2. 省略連接詞與主詞:刪除從屬連接詞和副詞子句的主詞

  3. 改寫動詞

    • 主動語態→ V-ing(現在分詞)

    • 被動語態→ V-p.p.(過去分詞)或 Being + V-p.p.

    • 否定形式→ Not + V-ing/V-p.p.

    • 完成式→ Having + V-p.p.(主動)或 Having been + V-p.p.(被動)

掌握副詞子句的簡化技巧,能讓你的英文寫作更加精煉優雅,特別在撰寫學術論文、商業報告或正式書信時,適當使用分詞構句能展現高階的語言掌握能力,這也是多益、托福、雅思等考試寫作部分獲得高分的關鍵技巧之一。

VI. 辨析:副詞子句 vs. 名詞子句 vs. 形容詞子句

英文的三大從屬子句常讓學習者混淆,透過句法位置與功能的對比,能快速掌握它們的本質差異。理解這三類子句的區別,是建立完整英文文法體系的重要基礎,也能幫助你在閱讀複雜句子時快速分析結構。

子句類型

句法位置

功能

連接詞範例

例句與說明

名詞子句

主詞(S)、受詞(O)、補語(C)位置

當名詞使用,可作為句子的主要成分

that,whether,if,what,who,when,where,why,how

  • What Xiaowang suggested in the meeting is worth considering.(小王在會議中建議的內容值得考慮。)——作為主詞

  • I know that the project deadline is next Friday.(我知道專案截止日期是下週五。)——作為受詞

形容詞子句

緊接名詞後方

修飾名詞,提供額外描述

who,whom,whose,which,that,where,when

  • The book that Xiaoming recommended is extremely helpful.(小明推薦的那本書極為有用。)——修飾 book

  • This is the café where we first discussed the business plan.(這是我們第一次討論商業計畫的咖啡廳。)——修飾 café

副詞子句

句首、句中、句尾(修飾位置)

修飾動詞、形容詞、副詞或整個句子

when,because,if,although,while,since,unless,so that

  • When the financial report is completed,we'll schedule the board meeting.(當財務報告完成時,我們會安排董事會議。)——修飾動詞 schedule

  • She is confident because she prepared thoroughly.(她很有信心,因為她準備得很充分。)——修飾形容詞 confident

進階辨析重點

有些連接詞如 when、where 可引導不同類型的子句,判斷關鍵在於它們的功能:

  • When she arrives is uncertain.(她何時抵達不確定。)——名詞子句,作主詞

  • I remember the day when we met.(我記得我們見面的那天。)——形容詞子句,修飾 day

  • When she arrives,call me.(當她抵達時打給我。)——副詞子句,修飾 call

掌握這個對照表能幫助你在閱讀與寫作時快速判斷子句類型,避免混淆三者的用法與位置,這對於理解複雜的學術文章或撰寫結構嚴謹的正式文件都極為重要。
