Would、Could、Might：改變現實感的小字

「Send me the file.」

直接。清楚。也可能是那種讓同事盯著螢幕，低聲說「也祝你早安」的句子。

「Could you send me the file?」

同一個請求，不同的溫度。

這就是 would、could 和 might 的魔力。它們是小字，卻能改變句子的心情。它們可以讓想法更柔和、更有禮貌、更不確定、更有想像空間、更謹慎，或更有幫助。它們不是裝飾品，而是現實控制鈕。

快速答案

Would、could 和 might 是 modal verbs。Modal verbs 放在另一個動詞的原形前面。

• would go
• could help
• might rain

後面不要加 to：

• could to help
• could help

不要加 -s：

• She could helps.
• She could help.

基本意思：

• Would 常表示想像、偏好、禮貌請求、過去重複習慣，或預期結果。
• Could 常表示能力、可能性、許可，或禮貌請求。
• Might 常表示可能性、不確定，或溫和建議。

它們常讓句子比 will、can 或 may 更不絕對。

模式

把這些字想成滑桿。

Will 強而直接：

• I will call you.

Would 把句子移進想像、禮貌或條件意義：

• I would call you, but my phone is dead.
• Would you call me later?

Can 是直接的能力：

• I can help.

Could 可以表示過去能力、較柔和的能力、可能性或禮貌請求：

• I could swim when I was five.
• I could help after lunch.
• Could you open the window?

May 可能聽起來正式：

• It may rain.

Might 聽起來更試探：

• It might rain.

文法形式很簡單：

subject + modal + base verb

• She would enjoy this.
• They could join us.
• We might need more time.

否定句：

• would not = wouldn't
• could not = couldn't
• might not = might not

談過去的 perfect forms：

modal + have + past participle

• would have gone
• could have helped
• might have missed

這些形式常談想像中或不確定的過去情況。

語氣差異很重要。Can you help? 直接詢問能力。Could you help? 更有禮貌地請求幫忙。Will you review this? 可以像普通的未來請求。Would you review this? 增加距離與柔和感。It may fail 可能聽起來正式或技術性。It might fail 通常更口語，也比較不確定。

這種距離很實用，因為不是每個句子都應該穿著重靴進場。在職場訊息、回饋、邀請與修正中，這些 modals 讓你能清楚表達，又不至於像警告標誌。

自然例句

Would 表示想像結果

當結果取決於想像條件時，使用 would。

• I would travel more if flights were cheaper.
• She would accept the offer if the schedule were flexible.
• They would move faster with clearer instructions.

條件可能說出來，也可能省略：

• That would be difficult.

隱藏意思是「如果我們那樣做」或「在那種情況下」。

Would 表示禮貌請求

Would 可以讓請求更順。

• Would you send me the agenda?
• Would you mind checking this paragraph?
• Would it be possible to reschedule?

當請求會花對方時間、注意力或耐心時，特別好用。

Would 表示偏好

用 would like 或 would rather 表示禮貌的偏好。

• I would like a receipt, please.
• We would like to start at 10.
• I would rather discuss this tomorrow.

Would 表示過去重複習慣

用 would 表示過去重複的動作，尤其在說故事時。

• Every summer, we would visit the same beach.
• After dinner, my grandfather would tell long stories.

對過去狀態，通常用 used to，不太用 would：

• I would live near the station.
• I used to live near the station.

Could 表示能力

用 could 表示過去能力或可能的能力。

• I could read music when I was younger.
• She could finish this by Friday if nothing urgent appears.
• We could use the smaller room.

Could 表示禮貌請求

Could 是英文裡最實用的請求字之一。

• Could you repeat that?
• Could I ask a quick question?
• Could we move the meeting to 2?

它聽起來比直接命令不那麼強硬。

Could 表示可能性

當某事可能但不確定時，使用 could。

• The delay could affect the launch.
• This could be a good solution.
• The keys could be in your bag.

Might 表示不確定

當某事可能但不確定時，使用 might。

• I might be late.
• She might not see the message in time.
• This answer might need more detail.

當你不想聽起來太肯定時，might 很有用。

Might 表示溫和建議

用 might 輕輕提出建議。

• You might want to save a backup copy.
• We might try a shorter introduction.
• It might help to add an example.

這通常比「You should」更圓滑。

Modal perfects：沒有走上的那條路

談過去可能性時，使用 would have、could have 和 might have。

• I would have joined, but I had another meeting.
• She could have finished earlier if the data had arrived.
• They might have misunderstood the instructions.

差異小但好用：

• would have：想像中的結果
• could have：可能的能力或錯過的機會
• might have：不確定的過去可能

這些形式常出現在謹慎解釋中。它們讓你能談沒有發生的事、曾經可能的事，或你不完全確定的事。

常見陷阱

陷阱 1：modal 後面加 to

• You could to call me.
• You could call me.

Modal verbs 直接接動詞原形。

陷阱 2：modal 後面加 -s

• She might knows.
• She might know.

主要動詞保持原形。

陷阱 3：用 could 表示一次成功的過去動作

表示一般過去能力時，could 可以：

• When I was ten, I could swim across the pool.

表示一次成功的過去動作時，使用 was able to 或 simple past。

• I could fix the printer yesterday.
• I was able to fix the printer yesterday.

陷阱 4：不小心讓請求太直接

「Give me your phone number」文法上沒錯，但常常太尖銳。試試：

• Could you give me your phone number?
• Would you mind sharing your phone number?

陷阱 5：混淆 might have 和 might

• She might forget the meeting. 未來或一般可能性。
• She might have forgotten the meeting. 可能的過去事件。

have + past participle 形式把可能性移到過去。

陷阱 6：每個禮貌句都用 would

禮貌不是一種尺寸套到底。Would 很有幫助，但 could 對請求通常更自然。

• Would you send me the file? 正確且有禮貌。
• Could you send me the file? 也正確，而且很常見。

邀請時，would you like 很適合：

• Would you like to join us?

徵求許可時，could I 通常自然：

• Could I ask a question?

錯誤 / 更好 / 原因

   c. might to

6. You _____ want to add a clearer example here.
   a. might
   b. mights
   c. might to

答案

1. a. Could - 禮貌請求使用 could + base verb。
2. a. might - 表示不確定的未來可能。
3. a. would - 想像結果使用 would + base verb。
4. a. might - 過去可能性使用 might have + past participle。
5. a. could - 這描述一般過去能力。
6. a. might - 這是溫和建議。

超短總結

Would、could 和 might 很小，卻會改變句子的力道。Would 常開啟想像結果、禮貌請求與偏好。Could 處理能力、可能性與禮貌請求。Might 加入不確定，或溫和地給建議。結構保持簡單：modal 加動詞原形。不要 to，不要 -s，不用慌。這些小字是英文調整音量、距離與信心的方式。
