常見錯誤

What are common mistakes with "Scan"?Which "Scan" sentences look correct but are wrong?

×I scanned the document to my computer.

I scanned the document into my computer.

使用 'scan' 表示將實體文件轉為數位檔案時,應搭配介系詞 'into' 或 'to' 加 'into'(scan into),而非單獨使用 'to'。'Scan to' 通常用於指定目的地裝置,如 'scan to email' 或 'scan to folder',但表示存入電腦時常用 'into'。

×I scanned the article, but I didn't find the information.

I skimmed the article, but I didn't find the information.

'Scan' 在閱讀情境中意指『快速瀏覽以尋找特定資訊』,帶有明確的搜尋目的。若只是快速閱讀以了解大意,而沒有特定的搜尋目標,應使用 'skim'。此處語意為未找到資訊,暗示是隨意瀏覽而非有目標地搜尋,故用 'skimmed' 更準確。

×The system is scanning for any viruses.

The system is scanning for viruses.

'Any' 在肯定句中常與複數名詞或不可數名詞連用,表示『任何一些』,但 'scan for' 後接的物件通常是泛指該類別的全部,使用複數名詞或不可數名詞即可,無需加 'any'。加 'any' 會使語意偏向『任何一些(可能存在的)病毒』,較不自然。

×I need to scan this barcode by my phone.

I need to scan this barcode with my phone.

表示使用工具或裝置進行掃描時,應使用介系詞 'with',而非 'by'。'By' 通常用於表示被動語態的行動者或方式,而 'with' 則表示使用的工具或手段。

×The doctor said he will scan my body tomorrow.

The doctor said he will do a scan on me tomorrow. / The doctor said I will have a scan tomorrow.

在醫療情境中,'scan' 作為名詞(指掃描檢查)比作為動詞(指掃描動作)更常見且自然。直接說 'scan my body' 聽起來過於字面且不專業。通常會使用 'have/do/get a scan'(接受掃描)或 'perform/do a scan on [部位]'(對某部位進行掃描)的說法。
