assuming that + clause vs assuming + noun phrase

易混淆對比
What is the difference between "Assuming" and similar words?How to choose "Assuming" vs alternatives?
assuming vs presume
「assuming」通常指在缺乏充分證據或未經證實的情況下，基於有限資訊或可能性而接受某事為真，語氣較為主觀或帶有條件性。而「presume」則更常指基於合理推論、已知事實或可能性極高的情況下，相信某事為真，語氣較為肯定或正式。
assuming vs suppose
「assuming」強調以某個條件為前提進行推論或計劃，帶有較強的假設性和條件性。而「suppose」則更通用，可表示單純的猜想、認為或提出一個假設情景，語氣較為中性或口語化。
assuming vs presuming
兩者皆可表示「假設」，但「assuming」更側重於以某個未經證實的條件作為行動或思考的基礎。而「presuming」則更強調在有一定依據或自信的情況下做出假設，有時帶有「擅自認定」或「冒昧」的含義。

在對話中，常用來引述或轉述他人的想法或假設，語氣較為隨意。 EN: He was just assuming you'd agree, so he went ahead and booked it. 翻譯: 他只是假設你會同意，所以就自己先預訂了。
EN:"I'm assuming the meeting is at 3?" she asked before leaving.
翻譯:她離開前問道：「我猜會議是三點吧？」
語氣強調
用於強調某個推測或前提，常與 "just" 或 "only" 連用，帶有「只不過是猜想」的意味。 EN: I'm just assuming based on what I heard, so don't quote me on that. 翻譯: 我只是根據聽到的來猜測，所以別說是我講的。
EN:That plan is only assuming the budget gets approved, which is a big if.
翻譯:那個計畫只是假設預算會通過，但這還是個很大的未知數。
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「呃」、「那個」。 EN: Well, assuming... um, that everything goes smoothly, we should finish by Friday. 翻譯: 嗯，假設…呃，一切順利的話，我們應該週五前能完成。
EN:The cost, assuming... let me think... around ten people attend, would be quite low.
翻譯:這個費用，假設…讓我想想…大概十個人參加的話，會相當低。
正式寫作注意：在正式報告或學術寫作中，應避免將 "assuming" 用作口語填充詞。建議使用更精確的結構，如 "provided that"、"on the assumption that" 或直接陳述條件，以保持文章的嚴謹性。

常見錯誤
What are common mistakes with "Assuming"?Which "Assuming" sentences look correct but are wrong?
×I am assume that you agree.
✓I am assuming that you agree.
將動詞原形 'assume' 與現在分詞 'assuming' 混淆。'Assuming' 是現在分詞或動名詞，在此句中需與 'am' 構成現在進行式。
×Assuming you finish on time, we can leave.
✓Assuming (that) you finish on time, we can leave.
雖然口語中 'that' 常被省略，但學習者應先熟悉完整結構 'assuming that...'，以明確引導條件子句。省略 'that' 雖可接受，但初學者可能因此誤解句子結構。
×Assuming it rains tomorrow, what will you do?
✓If it rains tomorrow, what will you do?
'Assuming' 用於說話者認為可能性較高或以此為前提進行推論的情況。對於單純的未來可能性或假設性問題，使用 'if' 更為自然。誤用 'assuming' 可能使語氣聽起來過於肯定或武斷。
×I assuming he is coming.
✓I assume he is coming.
將 'assuming' 誤用作主要動詞。'Assuming' 是現在分詞，不能單獨作為主要動詞使用。表達「我假設」應使用動詞原形 'assume'。
×We can start the meeting, assuming the boss arrives.
✓Assuming the boss arrives, we can start the meeting.
將 'assuming' 引導的條件子句放在句尾，可能導致語意模糊或邏輯重心錯誤。通常將條件子句置於句首，能更清楚地表達前提。
×Assuming he will come, we should book a larger table.
✓Assuming he comes, we should book a larger table.
在 'assuming (that)...' 引導的條件子句中，即使談論未來，也通常使用現在簡單式，而非 'will + 動詞'。這是英文條件句的常見時態規則。
