用法說明
How is "Assume" different from similar structures?What usage mistakes are common with "Assume"?
assume doing vs assume to do
- assume doing 通常用於描述「承擔（某項任務或責任）」或「呈現（某種狀態）」，後面接動名詞 (gerund) 表示已存在或持續的動作或狀態。
- assume to do 則較為少見且用法特殊，通常出現在「assume someone/something to be...」（假定某人/某物是...）的結構中，或與情態動詞如
would連用，表示「（錯誤地）自以為有權力做某事」或「擅自做某事」，帶有負面含義。 - 在表示「假設、認為」時，更常見的結構是 assume (that) + 子句，或 assume something。 EN: She assumed managing the project after John left. 翻譯: 約翰離開後，她接手管理這個專案。
EN:He would never assume to speak for the entire team without consulting us.
翻譯:他絕不會不經商量就擅自代表整個團隊發言。
EN:We assume the data being accurate for our initial calculations.
翻譯:我們初步計算時假設數據是準確的。
EN:I assumed him to be the new manager when I first saw him.
翻譯:我第一次見到他時，以為他是新來的經理。
總結建議
在大多數情況下，使用 assume (that) + 子句 或 assume + 名詞 來表達「假設」，而使用 assume doing 來表達「承擔（工作）」，應避免單獨使用 "assume to do" 來表示意圖或計劃。
易混淆對比

引述
在對話中，用來引述或轉述他人的想法、計畫或假設。 EN: So, if I assume you're coming, I'll book a table for five. 翻譯: 所以，如果我假設你會來，我就訂一張五人桌。
EN:Don't just assume I know what you're thinking.
翻譯:別只是假設我知道你在想什麼。
語氣強調
用於強調某個推測或前提，常與「let's」、「just」或「always」等詞連用，使語氣更自然。 EN: Let's assume for a moment that the meeting is cancelled. What's our backup plan? 翻譯: 我們先假設會議取消了。我們的備案是什麼？
EN:You always assume the worst will happen.
翻譯:你總是假設最壞的情況會發生。
停頓填充
在組織思緒或尋找合適字眼時，作為短暫的停頓填充詞，類似「let me see...」。 EN: Hmm, I assume... we could try calling them directly. 翻譯: 嗯，我假設…我們可以直接試著打電話給他們。
EN:The cost, I assume, would be around a thousand dollars.
翻譯:這個成本，我假設，大概是一千美元左右。
注意：在正式書寫（如報告、論文）中，應避免將 "assume" 用作停頓填充詞，並確保其引述的假設有明確的邏輯依據。

×I am assuming that he is coming.
✓I assume he is coming.
在表達一個普遍的假設或信念時，通常使用一般現在式 "assume"，而非現在進行式。現在進行式 "am assuming" 多用於強調說話當下正在進行的思考過程，較不常見。

×I assume her as a doctor.
✓I assume she is a doctor.
"assume" 表示「假定、認為」時，後面直接接子句 (that + S + V)，或直接接名詞（如：I assume her identity）。不接 "as + 名詞" 的結構。"regard as" 或 "think of as" 才用 "as"。
×We are all assume that the plan will work.
✓We all assume that the plan will work.
"assume" 是主要動詞，前面不應再有 "be" 動詞 (are)。"We are all" 後面應接形容詞 (e.g., We are all happy) 或現在分詞 (e.g., We are all assuming...)，但後者語意不同（見錯誤2）。
×I made an assume that he was guilty.
✓I made an assumption that he was guilty.
