Top 20 文法錯誤列表
- 動詞第三人稱單數不加 -s 錯誤：He go to school every day. 正確：He goes to school every day. 為什麼錯？：一般現在式，第三人稱單數主詞（he/she/it/單數名詞）動詞要加 -s 或 -es。 IELTS 影響：Writing Task 1 & 2 基礎語法錯誤，容易讓 Grammar 分數卡在 5.5–6.0。 小訣竅：看到主詞是 he/she/it/名字/單數，就立刻提醒自己「要加 s」。
- 現在完成式 vs 過去簡單式混淆 錯誤：I have been to London last year. 正確：I went to London last year. / I have been to London (但不能加明確過去時間)。 為什麼錯？：有明確過去時間（last year, yesterday, in 2020）不能用 have + pp。 IELTS 影響：Task 2 與 Speaking Part 2 最常見失分點之一。
- 冠詞 a/an/the 亂用或漏用 錯誤：I want to be doctor. 正確：I want to be a doctor. 錯誤：The life is beautiful. 正確：Life is beautiful.（抽象名詞通常不加 the） 小訣竅：可數名詞單數一定要有冠詞；抽象/泛指名詞大多不用。
- 可數 vs 不可數名詞單複數錯誤 錯誤：I have many homeworks. 正確：I have a lot of homework.（不可數） 錯誤：She gave me some advices. 正確：She gave me some advice. 小訣竅：advice, homework, information, furniture, luggage 都是不可數，永遠不加 s。
- 比較級與最高級形態錯誤 錯誤：This book is more cheaper than that one. 正確：This book is cheaper than that one. 錯誤：She is the most tallest in class. 正確：She is the tallest in class. 小訣竅：單音節形容詞直接 +er / est，雙音節以上用 more / most。
- 介係詞搭配錯誤（常見幾組） 錯誤：I’m good in English. 正確：I’m good at English. 錯誤：depend in 正確：depend on 錯誤：interested about 正確：interested in 小訣竅：把常見動詞+介詞當成一個單字記，例如 good at / depend on / interested in。
- 被動語態 be 動詞遺漏或形態錯 錯誤：The room clean every day. 正確：The room is cleaned every day. 錯誤：The book was wrote by him. 正確：The book was written by him. 小訣竅：被動語態一定要有 be + pp。
- 情態助動詞後面接原形動詞 錯誤：You must to study hard. 正確：You must study hard. 錯誤：She can sings very well. 正確：She can sing very well. 小訣竅：can/must/should/will/may 後面永遠接動詞原形。
- 連接詞誤用（although / but / however） 錯誤：Although it was raining, but we went out. 正確：Although it was raining, we went out.（although 後面不能再加 but） 錯誤：It was raining. However we went out. 正確：It was raining. However, we went out.（however 後要加逗號）
- 主詞與動詞一致性（複合主詞） 錯誤：My family like to travel. 正確：My family likes to travel.（family 視為單數單位） 錯誤：The news are shocking. 正確：The news is shocking.（news 是不可數）
- 不定詞 to + 原形 vs 動名詞 -ing 錯誤：I enjoy to play football. 正確：I enjoy playing football. 錯誤：I look forward to see you. 正確：I look forward to seeing you.
- 條件句時態錯誤 錯誤：If I have time, I will go.（未來假設） 正確：If I had time, I would go.（第二條件句）
- 關係子句 that / which / who 誤用 錯誤：The man which helped me is my teacher. 正確：The man who helped me is my teacher.（人用 who）
- 數量詞誤用 錯誤：There is a few students. 正確：There are a few students. 錯誤：Too much people came. 正確：Too many people came.
- 所有格 ‘s 與 of 混淆 錯誤：The book of John. 正確：John’s book. / The book of John（正式時可用，但日常偏好 ‘s）
- 形容詞順序錯誤 錯誤：a red big car 正確：a big red car（大小 → 顏色）
- 副詞位置錯誤 錯誤：She sings beautiful. 正確：She sings beautifully.
- 雙重否定錯誤 錯誤：I don’t have nothing. 正確：I don’t have anything. / I have nothing.
- too / very / enough 誤用 錯誤：It’s too much hot. 正確：It’s too hot. / It’s very hot.
- used to vs be used to 錯誤：I’m used to wake up early. 正確：I’m used to waking up early.（be used to + ing） 錯誤：I used to living here. 正確：I used to live here.（過去習慣 + 原形）
