Because、Although、However：打亂邏輯嘅句子連接詞
Academic Discussion 仲剩三分鐘。你有一個清晰嘅立場同一個唔錯嘅例子。你想承認對立觀點，然後反駁。你打：「Although public transit is cheaper, but it doesn't reach every neighborhood.」你繼續向前。一位評分員讀到嗰句會停一停——唔係因為個想法弱，而係因為兩個連接詞做緊同一份工，靜靜雞噉互相抵消。歡迎嚟到 TOEFL Writing 第二常見嘅文法漏洞。
連接詞係一個論證嘅隱形棚架。佢哋話畀讀者知每個想法點樣同下一個有關係：因果、對比、讓步、添加、順序。用得好，你嘅回應就算想法簡單都感覺有組織。用得差，就算想法強勁都讀落散修修。喺時間壓力下，學習者會伸手揀同樣嘅三個連接詞——because、although、however——而且喺出奇地一致嘅方式上面跣親。
點解呢樣嘢喺 TOEFL iBT 2026 好重要
喺 Reading 度，一篇文章嘅邏輯結構往往環繞單一個連接詞嚟轉。一句以 however、nevertheless 或者 on the other hand 開頭嘅句子，示意下一個主張同上一個矛盾——而 Read an Academic Passage 嘅推論模式好鍾意考你有冇留意到。喺 Listening 度，講者用 because 同 although 嚟標示主要想法同限定條件；錯過個訊號可以喺一條功能題上面整失你一分。
喺 Writing 度，賭注更加即時。TOEFL Writing 評分標準明確噉獎勵「想法之間有清晰連繫嘅良好發展推理」。連接詞係嗰啲連繫嘅可見訊號。一個列出三個好論點但唔將佢哋連接起嚟嘅回應，讀落係一疊意見。一個用精確連接詞將同樣三個論點接合嘅回應，讀落係一個論證。
喺 Speaking 度——尤其係 Take an Interview——你嘅評分員會聽邏輯標記，因為口語回應短而密。喺啱嘅位置用一個乾淨嘅 because，可以將一個回應抬高足足一分。
陷阱
三個連接詞造成大部分傷害。佢哋喺日常用法上面睇落可以互換，但係喺正式英文裏面行為好唔同。
Because。 Because 引入一個從屬子句。佢唔可以獨立成句。「Because public transit is cheaper.」係一個片段，唔係一句句子。喺時間壓力下，寫作者會將一個長想法拆成兩句句子，意外噉將一個 because 子句擱喺度。評分員每次都留意到。
Although 對 but。 Although 係一個引入讓步嘅從屬連接詞。But 係一個引入對比嘅對等連接詞。喺同一句裏面同時用兩個——「Although it is cheaper, but it is slower」——重複咗個邏輯動作，造成結構冗餘。揀一個；永遠唔好兩個都用。
However。 However 係一個副詞，唔係連接詞。佢唔可以淨係用一個逗號將兩個獨立子句黐埋一齊。「Public transit is cheaper, however it is slower」係一個逗號黏連。正確嘅形式係 分號 + however + 逗號：「Public transit is cheaper; however, it is slower.」或者兩句句子：「Public transit is cheaper. However, it is slower.」好多學習者會寫嗰個逗號黏連版本幾十次，先至有人標出嚟。
Nevertheless 對 on the other hand 對 however。 三個都示意對比，但係佢哋有唔同嘅味道。However 中性，喺幾乎任何語域都行得通。Nevertheless 示意「儘管我啱啱講過嗰啲嘢」。On the other hand 引入一個平行嘅替代選項——佢自然噉同段落較早出現嘅「on one hand」配對。當佢哋係完全嘅同義詞，就會令段落讀落機械化。
So 對 therefore 對 thus。 So 非正式，喺逗號之後嘅子句開頭行得通：「It was raining, so we stayed inside.」Therefore 同 thus 係正式副詞，需要更強嘅標點：「It was raining; therefore, we stayed inside.」喺一段裏面混埋非正式同正式形式會打破語域，尤其係喺語域被直接評分嘅 What's the Right Way to Write an Email on the TOEFL 2026? 回應入面。
錯 / 較好 / 點解
| 錯 | 較好 | 點解 |
|---|---|---|
| Although public transit is cheaper, but it doesn't reach every area. | Although public transit is cheaper, it doesn't reach every area. | 用 although 或者 but，唔好兩個都用——佢哋執行同一個讓步。 |
| The proposal is reasonable. Because it addresses both costs and access. | The proposal is reasonable because it addresses both costs and access. | 一個以 because 開頭嘅子句唔可以獨立成為一句完整句子。 |
| Many students prefer remote classes, however attendance is harder to track. | Many students prefer remote classes; however, attendance is harder to track. | However 係副詞，需要一個分號（或者一句新句子），唔係淨係一個逗號。 |
| She studied for weeks, therefore she passed. | She studied for weeks; therefore, she passed. | Therefore 用分號連接兩個獨立子句。 |
| Despite of the rain, we walked to class. | Despite the rain, we walked to class. | Despite 直接接一個名詞，冇 of。 |
| In spite the cost, the program is worth it. | In spite of the cost, the program is worth it. | In spite of 永遠包含 of。 |
| He failed the test. So that he had to retake it. | He failed the test, so he had to retake it. | So（結果）係一個字；so that（目的）意思唔同。 |
| Public libraries are quiet, also they are free. | Public libraries are quiet, and they are also free. | Also 係副詞，唔係對等連接詞——佢需要一個真正嘅連接詞或者一句新句子。 |
邊度會出現
Write for an Academic Discussion。 一個 130 字嘅回應通常包含兩三個連接詞。每一個對評分員嚟講都高度顯眼。喺一個短回應入面，單單一個用 however 嘅逗號黏連，就足夠拉低個感知到嘅組織性。
Read an Academic Passage 同 Listen to announcements and academic talks。 學術來源刻意用 however、on the other hand、nevertheless 同 despite this 嚟標示對比。如果你喺練習總結同 Writing 回應入面正確噉呼應嗰啲連接詞，你就示意你理解咗個結構。如果你用含糊嘅 and 或者 also 嚟代替佢哋，你就將個對比壓平。
Read an Academic Passage 嘅推論模式。 條題目往往環繞單一個 however、yet、while 或者 whereas 嚟轉。知道第二個子句係支持、限定，定係矛盾第一個，就係成個技巧。
Speaking 任務。 喺一個短口語回答入面用一個受控嘅 because 顯示推理。喺口語回答入面避免堆疊 and... and... and...；一個放得啱位嘅 however 令個回應聽落有組織。
快速修正
三條規則會喺考試壓力下捕捉到大部分連接詞錯誤。
第一，一個以 because 開頭嘅子句必須黐住一個主句。如果一句句子淨係由「Because students need more time」組成，將個句號推返後，將個子句連接到主要想法。
第二，although 同 but 永遠唔共享一句句子。一打 although 喺句首，就喺心入面擦走任何想喺後面出現嘅 but。淨係用 but，或者淨係用 although——永遠唔好兩個都用。
第三，however、therefore、nevertheless、moreover、furthermore、thus 同 consequently 連接兩個子句時全部都需要一個分號。喺呢啲字前面用逗號幾乎一定造成逗號黏連。安全嘅替代方法係一句新句子：寫一個句號，然後用個連接詞加一個逗號嚟開始下一句句子。
一條簡短嘅第四規則有助你嘅回應更加精緻：唔好每一句句子都用同一個連接詞開頭。如果你最後三句句子全部都以 however 開頭，就用 yet、that said 嚟變化，或者重組將個對比放入句子裏面（「While X is true, Y matters more」）。變化讀落係一種掌控。
小練習
- 修正連接詞冗餘：Although the article was short, but it covered all the main points.
- 修補片段：The professor extended the deadline. Because many students were sick that week.
- 修正逗號黏連：Online lectures are convenient, however they limit student interaction.
- 揀啱嘅連接詞並加標點：The data was incomplete (therefore / so / however) the team had to repeat the experiment.
- 用單一個精確嘅連接詞改寫：Public libraries are free. They are quiet. Also, they have reliable Wi-Fi.
可能嘅改良版本：(1) Although the article was short, it covered all the main points. (2) The professor extended the deadline because many students were sick that week. (3) Online lectures are convenient; however, they limit student interaction. (4) The data was incomplete; therefore, the team had to repeat the experiment. (5) Public libraries are free, quiet, and reliably equipped with Wi-Fi.
提交前要檢查啲咩
喺任何 Writing 或者 Email 任務最後嘅六十秒，做一次連接詞掃描。視覺上搵任何句子開頭嘅 because——如果你搵到一個，檢查佢有冇接到一個主句。搵 however、therefore、nevertheless、moreover、thus 同 furthermore——每一個都需要一個分號或者一句新句子，永遠唔好得一個孤單嘅逗號。喺成個回應裏面任何地方搵 although——如果同一句句子出現一個 but，刪走其中一個。最後，喺心入面大聲讀返個回應：如果每一句句子都以同一個連接詞開頭，至少變化其中一個。一個乾淨嘅連接詞層唔淨止修正文法——佢令一個 Band 4 回應感覺好似 Band 5。
