Examiner 改一篇 Task 2，前 30 秒就能察覺幾件事：段落結構、時態控制、以及——標點。

標點錯一個：Band 7 → 可能還保得住。錯五六個：直接降到 Band 6。大多數台灣考生把標點當小事——這是 IELTS Writing 最被低估的扣分項目。

本篇整理 IELTS Writing 最關鍵的 6 種標點規則：逗號、分號、冒號、破折號、撇號、引號。

先看 被動語態攻略 與 條件句攻略。

1. 逗號（Comma）

最常用、也最常錯的標點。五個核心規則：

規則 1：列舉三項以上

Education, healthcare, and infrastructure all require sustained investment.

Oxford comma 爭議：healthcare, and 這個最後一個逗號——IELTS 用或不用都接受。建議統一用 Oxford comma（避免歧義）。

規則 2：連接詞連接兩個獨立子句時

當 and, but, so, yet, or, nor 連接兩個完整的句子，前面加逗號。

✓ The policy was introduced in 2015, and it has already produced measurable results. ✗ The policy was introduced in 2015 and has already produced results.（一個主詞兩個動詞——不加）

規則：兩邊都有獨立主詞 → 加逗號；共用主詞 → 不加。

規則 3：句首副詞子句後

Although the policy has been criticised, its results speak for themselves. Since 2015, emissions have fallen by 12%. In contrast, rural areas have seen little change.

規則：句首副詞 / 副詞子句後一定加逗號。

規則 4：非限定子句（non-defining）兩邊加逗號

The report, which was published last year, has already influenced policy.（非限定——可省略） The report that was published last year has already influenced policy.（限定——不可省略，不加逗號）

規則：which 引導的非限定子句兩邊都要加逗號；that 限定子句不加逗號。

規則 5：句中插入語

Taiwan, unlike most of its neighbours, maintains universal healthcare. This approach, in my view, overlooks the underlying cause.

逗號最嚴重錯誤：Comma Splice

兩個獨立子句中間只用逗號——這是 IELTS 最常扣分的標點錯誤之一。

❌ The policy was popular, it achieved its stated goals.

兩個完整句子，中間只用逗號——錯。

4 個修法

✓ The policy was popular; it achieved its stated goals.（分號） ✓ The policy was popular, and it achieved its stated goals.（加連接詞） ✓ The policy was popular. It achieved its stated goals.（句號拆成兩句） ✓ The policy was popular because it achieved its stated goals.（從屬連接詞）

2. 分號（Semicolon）

Band 7+ 的標誌之一——大多數台灣考生沒用過。

用法 1：連接兩個緊密相關的獨立子句

The policy was controversial; nevertheless, it passed. Urban areas have seen rapid growth; rural regions have stagnated. Education matters enormously; without it, social mobility collapses.

規則：分號兩邊必須都是完整句子，語意緊密相關。如果語意不緊密，用句號。

用法 2：分隔內部含逗號的列舉項目

The study surveyed participants from Taipei, Taiwan; Seoul, South Korea; and Tokyo, Japan.

何時用分號、何時用句號？

| 情境 | 選擇 | |----------------------------|-------| | 兩句關係緊密、互相補充 | 分號 | | 兩句可獨立存在、無直接關係| 句號 | | 想加連接詞（and, but） | 逗號 + 連接詞 |

Band 7+ 秘訣：一篇 Task 2 essay 用 1-2 個分號——Examiner 立刻看到文法廣度。用 5 個就過頭。

3. 冒號（Colon）

用法 1：引出解釋、列舉、例子

Three factors drive this trend: urbanisation, ageing, and migration. The conclusion is clear: action must begin now.

規則：冒號前面必須是完整句子。

❌ The three factors are: urbanisation, ageing, migration.（are 後面不完整——錯） ✓ The three factors are urbanisation, ageing, and migration.

用法 2：引出重要結論或引言

The data suggests one outcome: further delay will prove catastrophic.

4. 破折號（Dash / Em-dash）

不是連字號（hyphen）——是更長的 em-dash：—。

用法：插入補充資訊或強調

The policy — widely criticised at the time — has since been vindicated. Three factors drove the decline — weather, demand, and regulation. Education matters — but so does opportunity.

破折號 vs 逗號 vs 括號

| 標點 | 語氣 | |--------|---------------| | 逗號 | 中性、流暢 | | 破折號 | 強調、戲劇性| | 括號 | 次要、附註 |

Band 7+ 建議：一篇 essay 用 1 次 em-dash——錦上添花，但不要依賴。用太多顯得隨意。

5. 撇號（Apostrophe）

用法 1：所有格

the government's policy（單數所有格） students' exam results（複數所有格） children's education（不規則複數）

用法 2：縮寫

it's = it is don't = do not I'm = I am

最常見錯誤：its vs it's

❌ The policy achieved it's goals. ✓ The policy achieved its goals.（所有格——沒撇號） ✓ It's clear that the policy succeeded.（it is 的縮寫——有撇號）

關鍵規則：學術寫作避免縮寫（don't, isn't, I'm, won't）。Task 2 正式語氣——寫 do not, is not, I am, will not。

6. 引號（Quotation Marks）

IELTS Writing 的引號用法

學術 essay 很少直接引用——但偶爾需要：

用法 1：直接引用

As Keynes famously observed, "In the long run, we are all dead."

用法 2：特殊術語首次出現

The phenomenon of "qualification inflation" has pushed employers to demand more credentials.

用法 3：不表示字面意義

These so-called "reforms" have achieved little beyond rhetorical impact.

規則：IELTS Task 2 不鼓勵直接引用（你也沒來源可查）——用轉述比較安全。參考 轉述句攻略。

標點優先順序——Band 7+ 的 80/20

如果時間有限，只改這三個地方標點錯誤：

  1. Comma splices（兩獨立子句只用逗號）——最嚴重
  2. its vs it's——最常錯
  3. 句首副詞後沒加逗號——最常漏

把這三個修好，你的 Grammar Accuracy 從 Band 6 → Band 7。

標點不要做的事

| 不要做 | 為什麼 | |-------------------------------|--------------------------------| | 用 ! 驚嘆號 | 不符學術語氣 | | 用 ... 省略號 | 不夠正式 | | 用連字號 - 當 em-dash | 視覺上錯誤 | | 縮寫 don't, can't, I'm | 學術 essay 要全寫 | | 每句都用分號 | 過度使用失去效果 | | 中文全形標點 ，。； | 英文 essay 一律半形 |
