用法說明
How is "Extend" different from similar structures?What usage mistakes are common with "Extend"?
extend doing vs extend to do
- extend doing 通常不自然，因為 "extend" 作為及物動詞時，後面通常接名詞（如時間、範圍、邀請），而非動名詞片語。
- extend to do 也較為少見，但可能出現在較正式的語境中，表示「將某事物（如邀請、優惠、影響力）擴大到涵蓋做某事的範圍」。更常見的結構是 extend something to someone 或 extend into/over something。
- 表達「延長做某事的時間」時，更自然的說法是 extend the time for doing something 或 extend the period of doing something。
- 在假設或禮貌性提供某事物時，可能會用到 would be happy to extend an invitation to you to attend... 這類較長的結構。 EN: The company decided to extend the deadline for submitting proposals. 翻譯: 公司決定延長提交提案的截止日期。
EN:The scholarship program may extend to cover postgraduate studies next year.
翻譯:這項獎學金計畫明年可能會擴大到涵蓋研究生課程。
總結建議
使用 "extend" 時，最常見且自然的結構是後接名詞受詞（extend something），或使用 "extend to + 名詞" 表示範圍擴大，應避免直接接 "doing" 或 "to do"。
易混淆對比
What is the difference between "Extend" and similar words?How to choose "Extend" vs alternatives?

extend vs stretch
「extend」強調使某物達到更遠點或更長狀態；「stretch」強調通過拉拽使其長度或彈性發生變化。

引述
在引述他人要求或提議時，常用來緩和語氣，表示這不是自己的主意。 EN: So, they want to extend the deadline by a week. 翻譯: 所以，他們想把截止日期延長一個禮拜。
EN:She said we could extend the offer until Friday.
翻譯:她說我們可以把這個提議延長到週五。
語氣強調
與「really」、「actually」等副詞連用，強調延長的動作或程度，帶有意外或強調的語氣。 EN: We actually had to extend our stay because of the storm. 翻譯: 我們因為暴風雨，實際上不得不延長停留時間。
EN:I really need to extend this cable; it's way too short.
翻譯:我真的需要延長這條線，它實在太短了。
停頓填充
在思考或組織語句時，用來填充停頓，常以「extend that...」、「extend it...」等形式出現。 EN: The plan is to, you know, extend the project into the next quarter. 翻譯: 計畫是，你知道的，把這個專案延續到下一季。
EN:We should... extend an invitation to the new team as well.
翻譯:我們應該…也向新團隊發出邀請。
正式寫作注意：在正式書面語（如報告、論文）中，應避免上述口語用法，直接使用「extend」陳述事實，並減少填充詞和過於個人化的語氣強調。

常見錯誤
What are common mistakes with "Extend"?Which "Extend" sentences look correct but are wrong?
×I want to extend my visa for another year.
✓I want to extend my visa for another year.
雖然句子本身正確，但學習者常將 'extend' 與 'renew' 混淆。'Extend' 指延長現有事物的長度或期限，而 'renew' 指重新開始或更新一個已到期的合約、證件等。例如，簽證到期後重新申請應使用 'renew'。
×Can you extend the meeting time?
✓Can you extend the meeting? / Can we extend the meeting time?
學習者常直接將中文「延長時間」逐字翻譯為 'extend the time'，但在英文中，'extend' 的受詞通常是事件本身（如 meeting, deadline, visit），或使用 'extend the duration'。'Extend the time' 聽起來不自然，除非在特定上下文（如 extend the time limit）。
×He extended his arm to reach the book.
✓He reached out his arm to get the book. / He stretched out his arm to reach the book.
描述物理上的「伸出手臂」時，'extend' 較為正式或書面化，常用於描述範圍或線性延伸（如道路、鐵路）。在口語或描述具體身體動作時，更常使用 'reach out', 'stretch out', 或 'hold out'。
×We extended the invitation for him to join the party.
✓We extended an invitation to him to join the party.
表達「發出邀請」時，固定搭配是 'extend an invitation to someone'，而不是 'extend the invitation for someone'。介系詞 'to' 用於指向接受邀請的對象。
×I will extend my thanks to everyone.
✓I would like to extend my thanks to everyone. / I extend my thanks to everyone.
'Extend thanks/greetings/apologies' 是正式的表達方式，常用於書信、演講或公告中。在即時、非正式的對話中直接說 'I will extend...' 聽起來不自然。通常使用 'I would like to extend...'（較禮貌）或現在式 'I extend...'（用於正式聲明）。
