用法說明
How is "Guarantee" different from similar structures?What usage mistakes are common with "Guarantee"?
guarantee doing vs guarantee to do
- guarantee doing 強調「保證某個行為或事實的發生」，後接的動名詞（V-ing）本身代表一個已確定或將被確保的事件或狀態。
- guarantee to do 強調「保證會去做某個動作」，後接的不定詞（to V）帶有「意圖」和「未來承諾」的意味，動作由主語執行。
- 在許多情況下，兩者可以互換使用，語意差異細微。但在正式或法律文件中，guarantee doing 可能更側重於「確保結果」，而 guarantee to do 更側重於「承諾履行」。
- 被動語態中，通常使用 be guaranteed to do 的形式，表示「被保證會…」。 EN: The contract guarantees delivering the goods by Friday. 翻譯: 這份合約保證在週五前送達貨物。
EN:We guarantee to deliver the goods by Friday.
翻譯:我們保證會在週五前送達貨物。
EN:This process guarantees achieving consistent results.
翻譯:這個流程保證能取得一致的結果。
EN:I guarantee to finish the report before the deadline.
翻譯:我保證會在截止日期前完成報告。
總結建議
在大多數日常情境中，guarantee to do 用於個人承諾某個將執行的動作，而 guarantee doing 則用於確保某個事件或結果的發生，兩者常可通用。
易混淆對比
What is the difference between "Guarantee" and similar words?How to choose "Guarantee" vs alternatives?
guarantee vs ensure
「guarantee」強調正式承諾或擔保結果，常帶有法律或商業責任；「ensure」側重於採取措施以確保某結果發生，更通用。
guarantee vs promise
「guarantee」通常指更正式、具體的擔保，常與產品、服務或結果掛鉤；「promise」是更個人化、廣泛的承諾，可能基於誠信。
guarantee vs assure
「guarantee」強調對事件或結果的客觀擔保；「assure」側重於向某人「保證」以消除其疑慮或恐懼，對象常是人。

停頓填充

EN:It's going to rain later, guarantee.
翻譯:待會兒一定會下雨，我保證。

常見錯誤
What are common mistakes with "Guarantee"?Which "Guarantee" sentences look correct but are wrong?
×I guarantee you to get the job.
✓I guarantee (that) you will get the job.
「guarantee」作為動詞時，後面通常接「that」子句或名詞，不接「人 + to + 動詞」的結構。
×This ticket guarantees you for a seat.
✓This ticket guarantees you a seat.
「guarantee」在表示「保證某人得到某物」時，使用「guarantee + 人 + 物」的雙賓語結構，中間不需要介系詞「for」。
×We guarantee for the quality of our services.
✓We guarantee the quality of our services.
「guarantee」作為及物動詞時，後面直接接名詞作為受詞，不需要介系詞「for」。名詞「guarantee」才常與「for」連用。
×I guarantee, the weather will be fine tomorrow.
✓I guarantee (that) the weather will be fine tomorrow.
在正式或書面語中，「guarantee」後面引導子句時，通常會使用連接詞「that」（口語中可省略），但不應使用逗號直接連接兩個獨立子句。
×Eating healthy is a guarantee to not get sick.
✓Eating healthy is no guarantee against getting sick. / Eating healthy does not guarantee that you won't get sick.
使用名詞「guarantee」表示「保證」時，常見的搭配是「no guarantee of/against...」或「a guarantee that...」。使用「a guarantee to + 動詞」的結構並不自然。動詞形式在此語境下更為常見且自然。
