Would 用法：意思、句型與 Will、Should、Could、Might 的差別

Would 是英文中最常用的情態動詞之一，但也容易與 will、could 或 used to 混淆。在本文中，ELSA Speak 將帶你了解 would 意思、would後面加什麼、would 用法、would like用法、would you用法，並透過易懂的例句區分 can could will would 用法。 

Would 是什麼？

Would是一個情態動詞（modal verb），通常被視為will的過去式。然而，在現代英文中，would不僅用於表達”過去的未來”，還可用於表達假設、禮貌性提議、願望、過去的習慣等多種情境。 

例句：

• She said she would come tomorrow. (她說她明天會來。)
• Would you help me? (你能幫我嗎？)
• If I had more time, I would travel around the world. (如果有更多時間，我會環遊世界。)

Would後面加什麼？

Would 後面必須接不加 to 的原形動詞（bare infinitive）。根據不同語境，would會搭配不同結構，用於表達過去未來式、假設、願望或過去未發生的事情。 

結構	用法
Would + V (原形動詞)	表達過去未來式、假設或禮貌性提議
Would + not + V	would的否定句
Would + be + N/Adj	在假設或過去未來式情境中表達狀態或職業
Would + have + V3/ed	表達過去未發生的事（第三條件句、遺憾）
Would + like + N/to V	表達願望或禮貌性邀請

注意：would後面不接 to + V或V-ing。一律使用原形動詞（固定結構如 would like to + V 或 would have + V3/ed 除外）。 

英文 would 用法

Would是英文中用法最多的情態動詞之一。根據不同語境，would可用於表達過去的未來、條件句、禮貌性提議、願望或過去的習慣。以下是你需要熟練掌握的would常見用法。 

Would 作為 will 的過去式  (Future in the Past)

Would用於描述從過去某時間點看來屬於未來的動作或計劃。 

句型結構：

S + would + V (原形動詞)

例句：

• She said she would come the next day. (她說她隔天會來。)
• I knew he would pass the exam. (我知道他會通過考試。)

Would 表達預測或可能性

Would 可用於作出預測或推測，確定程度低於 will，通常帶有“或許”、“大概”的含義。 

例句：

• That would be Jack at the door. (應該是 Jack 在門外。)
• She would probably agree with you. (她大概會同意你的看法。)

Would 表達過去的習慣 

Would可用於表達過去反覆發生的動作，類似 used to 用法。 

句型結構：

S + would + V (原形動詞)

例句：

• Every summer, we would go camping. (每個夏天，我們通常會去露營。)
• My grandmother would tell us stories every night. (我奶奶每天晚上都會給我們講故事。)

注意：would 僅表達習慣或反覆發生的動作，而 used to 可同時表達過去的習慣與狀態。 

Would 用於提出禮貌性提議或請求 

Would you用法是使用 Would you……？結構，以禮貌的方式提出請求、邀請或提議。這在日常溝通與職場環境中都是常見的表達方式。 

句型結構	例句
Would you + V…?	Would you open the window? (你能幫我開窗嗎？)
Would you mind + V-ing…?	Would you mind closing the door? (你介意幫我關門嗎？)
Would you please + V…?	Would you please wait a moment? (你能稍等一下嗎？)

Would 用於表達願望 

要表達願望或偏好，would 常與多種不同結構搭配使用。以下 ELSA Speak 將說明 would like用法與 would rather用法，並附結構、例句及詳細區分。 

句型結構	用法	例句
Would like + N	想要某樣東西	I’d like a cup of tea. (我想要一杯茶 。)
Would like + to V	想做某事	We’d like to travel to Japan. (我們想去日本旅遊 。)
Would rather + V	比較喜歡做……	I’d rather stay at home. (我比較想待在家 。)
Would prefer + to V	想要或偏好……	She’d prefer to drive. (她比較想自己開車 。)

Would 在 if條件句中 

了解 would 的正確位置與使用方法如果出現在 if 用法裏： 

If would用法：第二條件句

用於描述現在或未來不真實的情境。 

句型結構：

If + S + V2/V-ed, S + would + V

例句：If I were you, I would accept the offer. (如果我是你，我會接受這個提議。)

If would用法：第三條件句 

用於描述過去未曾發生的事情。 

句型結構：

If + S + had + V3/ed, S + would have + V3/ed

例句：If they had left earlier, they would have caught the train. (如果他們早點離開，就能趕上那班火車了。)

Would 在間接引語中

將直接引語轉換為間接引語時，will 通常改為 would。 

句型結構：

S + said (that) + S + would + V

例句：

• She said she would help me. (她說她會幫我。)
• They told us they would arrive on Friday. (他們告訴我們他們星期五會來。)

Would與其他情態動詞的區分 

區分 will would 用法 

儘管兩者都可用於描述未來，will 與 would 在確定程度、時間與使用語境上有所不同。 

	Will	Would
確定程度	確定、預測程度高	較不確定，帶有假設性
未來	表達未來	過去的未來或假設
過去	不使用	在間接引語中作為will的過去式
禮貌程度	語氣較直接	提出請求或提議時更禮貌
假設	不使用	常用於條件句

例句：

• I will call you tomorrow. (我明天會打電話給你。)
• I would call you if I had your number. (如果我有你的號碼，我會打電話給你。)

區分 could should would 用法

	Would	Could	Should
主要意思	願望、假設、禮貌	能力、可能性	建議、義務、期望
表達願望	✔️	✖️	✖️
表達可能性	✖️	✔️	✖️
禮貌性提議／請求	✔️	✔️ (強調可能性 )	✖️

例句：

• She could speak French when she was young. (她小時候會說法語。)
• You should study harder. (你應該更認真學習。)

區分 used to would用法

Would 與 used to 都可表達過去的習慣，但用法並不完全相同。 

	Would	Used to
過去的習慣	✔️	✔️
過去的狀態	✖️	✔️
反覆發生的動作	✔️	✔️

注意：Would 僅用於反覆發生的動作，而 used to 可同時用於過去的狀態與習慣。 

例句：

• My grandfather used to live in the countryside. (我爺爺以前住在鄉村。)

Could	可以（過去）、可能性	過去的能力、禮貌性提議	Could you help me? (你能幫我嗎？)
