TOEIC 那些「看起來太簡單」的介系詞陷阱
你正在 TOEIC Part 5 一路順順地寫,平均一題二十秒、毫無壓力。然後你撞到這題:
"Please submit your report _____ Friday."
A) by B) until C) at D) on
你停了一下。好像四個都通?你選了「until」因為聽起來最合理,繼續往下寫,然後悄悄丟掉了一分本來不該丟的分。TOEIC 介系詞陷阱的可怕之處不是題目很難,而是題目「看起來」太簡單,於是你停止仔細讀題。
中文母語者特別容易在這裡踩坑,因為很多商用英文搭配跟中文直譯出來的版本剛好相反。「在 3 點開會」直譯就想用 in,但英文要 at;「30 天內付款」直譯成 in 30 days,但英文要 within;「支票開給供應商」直譯想成 for 或 give,英文卻是 payable to。
來看看命題者在商用情境裡反覆使用的固定模式,這樣你下次就能提前認出它們。
快速解答
- TOEIC 介系詞題在考「固定搭配」,不是在考文法規則。
- 四大陷阱區:時間(by/until/within)、地點(at/in/on 用於辦公室)、email 用語(in/on/at + 文件)、付款(within/by/to)。
- 策略:記固定搭配本身,不要記某一個具體的句子。
核心規則
- By = 截止時間(不晚於那個時間點)。
- Until = 動作持續到某個時間點為止。
- Within = 在某個時間窗口之內。
- 商用地點:at = 具體某個點、in = 封閉的空間、on = 樓層/表面。
真實例句
截止時間與日期
- Please submit the report by Friday.(要在星期五當天或之前完成。)
- The office will be closed until Monday.(一直關到星期一。)
- Payment is due on the 15th.(具體日期。)
- The proposal must be finalised by end of day.(截止時間。)
- All invoices are payable within 30 days.(在 30 天的窗口之內。)
會議與排程
- The conference call is at 3 p.m.(具體時間。)
- Our next review is on the 12th.(具體日期。)
- Annual targets are reviewed in Q4.(在一個較大的時段之內。)
- The meeting starts at 9:30 sharp.(時鐘上的時間永遠搭 at。)
- The training session is scheduled for next Tuesday.("For" 用在「排定的活動」。)
Email 與文件用語
- Please see the figures in the attached spreadsheet.(在檔案裡面。)
- That item is on the agenda for tomorrow.(列在議程這個「表面」上。)
- I'll respond at your earliest convenience.(固定片語,永遠是 at。)
- The contract is under review.(狀態片語。)
- Details are in section 3 of the proposal.
辦公室地點
- Please check in at the front desk.(具體某個點。)
- The all-hands is in the main conference room.(封閉空間。)
- HR is on the third floor.(樓層永遠用 on。)
- The printer is in the corner of the break room.
發票與付款
- Please remit payment within 14 days of receipt.
- Make the cheque payable to Greenfield Solutions Ltd.
- The amount will be charged to your corporate account.
- A late fee applies after 30 days.
常見錯誤
- ❌ "Please reply until Friday." → ✅ "Please reply by Friday." · Until 是「一路持續到那個時間點」,by 才是「在那個截止點之前」── 商用情境幾乎永遠要的是後者。
- ❌ "The meeting is in 3 p.m." → ✅ "The meeting is at 3 p.m." · 時鐘上的具體時間永遠用 at,不會用 in。
- ❌ "Make the cheque payable for the supplier." → ✅ "Make the cheque payable to the supplier." · "Payable to" 是商用世界的固定片語。
- ❌ "The report is in the agenda." → ✅ "The report is on the agenda." · 議程被當作「表面上的清單」,所以用 on。
- ❌ "Please respond on your earliest convenience." → ✅ "Please respond at your earliest convenience." · 商用固定片語;只有 at 這個版本存在。
- ❌ "Our office is in the third floor." → ✅ "Our office is on the third floor." · 英文裡「樓層」永遠用 on,雖然辦公室本身是 in 這棟樓。
- ❌ "Payment is due in 30 days from now." → ✅ "Payment is due within 30 days." · Within 才正確框出「窗口」;in 30 days 意思是「剛好第 30 天那天」。
考試陷阱
TOEIC 介系詞陷阱有三層。第一層:四個選項都是常見又合理的介系詞,無法靠直覺刪掉任何一個。第二層:題幹通常很短,只有一句話,你拿不到太多上下文線索。第三層:考試會重複使用固定的商用片語(payable to、at your earliest convenience、on the agenda、within 30 days),這些你就是必須整組記下來。修法不是去刷上千題練習題期待自己有一天會通靈,而是把這些片語以 chunk 為單位記住,就像背 "good at" 或 "afraid of" 一樣 ── 一個單位、不能拆。重要提醒:不要 試圖背實際的 TOEIC 試題本身。除了違規之外,真實題目會退役、會更新,唯一會延續下去的是「模式」。學模式,永遠不要去背特定句子。
小試身手
- The application must be submitted _____ 5 p.m. on Friday.
- The supply room is _____ the second floor, next to the kitchen.
- Please remit payment _____ 30 days of receiving the invoice.
- Make the cheque payable _____ ABC Industries Ltd.
- Your meeting is scheduled _____ 10:30 a.m. _____ Thursday.
解答
- by ── 提交截止時間永遠用 by,意思是「不晚於那個時間」。
- on ── 商用英文裡樓層永遠搭 on,不會是 in。
- within ── "Within 30 days" 才正確框出「窗口」;in 30 days 會被解讀成「剛好第 30 天」,這不是發票要表達的意思。
- to ── "Payable to" 是商用固定片語,其他介系詞在這裡都不通。
- at / on ── 時鐘時間搭 at、星期幾搭 on ── 一個短句裡同時出現兩個介系詞,是非常經典的 TOEIC 題型。

TOEIC 介系詞題獎勵的是「模式辨識」,不是「死背個別句子」。把上面這張表練到變成肌肉記憶,那些「看起來太簡單」的題目就真的會變簡單。
