用法說明
How is "From" different from similar structures?What usage mistakes are common with "From"?
from doing vs from to do
- from doing 是正確的結構，用於表示「阻止、防止、避免」某人或某物進行某個動作。介系詞 from 後面必須接動名詞 (V-ing)。
- from to do 是錯誤的結構。介系詞 from 後面不能接不定詞 (to + V)。
- 常見的動詞搭配包括 prevent...from doing, stop...from doing, keep...from doing, prohibit...from doing。
- 在這些結構中，from 有時可以省略，尤其是在口語中，但保留 from 能讓語意更清晰。
對比範例： EN: The rain prevented us from going out. 翻譯: 下雨阻止了我們外出。
EN:The fence stops the dog from running into the street.
翻譯:柵欄防止狗跑到街上。
總結建議
建議記住「from + V-ing」的固定搭配，並避免使用不存在的「from to do」結構。
易混淆對比
What is the difference between "From" and similar words?How to choose "From" vs alternatives?
from vs since
「from」和「since」都可用來表示時間的起點，但「since」強調從過去某一特定時間點持續到現在（通常與完成式連用），而「from」僅表示起點，不暗示持續性。
from vs of
「from」常表示來源、起點或分離；「of」則多表示所屬、材料或部分關係。在表示「來自某地」或「由...製成」時容易混淆。
from vs out of
「from」表示一般性的來源或起點；「out of」則強調「從...內部出來」或「由...組成」，更具體地描述從某範圍內離開或產生的過程。

引述
在口語中，from 常用來引述或轉述他人的話語或想法，表示來源。

翻譯: 他當時就說：「我從一個朋友那裡聽來的。」
EN:So I was all, "Where are you from?"
翻譯:所以我就說：「你從哪裡來的？」
語氣強調
在非正式對話中，from 有時會與其他詞結合，用於強調時間、地點或狀態的起點，語氣較強。
EN: I've been waiting from like, two o'clock!
翻譯: 我從大概兩點就等到現在了！
EN:This is totally different from what you said before.
翻譯:這跟你之前說的完全不一樣。
停頓填充
在思考或組織語句時，from... 結構有時會被用作停頓填充，特別是當說話者試圖回憶或舉例時。
EN: We need someone... from, uh, the marketing department.
翻譯: 我們需要一個…呃，從行銷部門來的人。
EN:It could be anything from, you know, a gift to just a call.
翻譯:這可能是任何東西，你知道，從一份禮物到只是一通電話。
注意：以上用法多見於非正式口語對話，在正式書寫或學術文章中應避免使用過於鬆散或填充式的結構。

常見錯誤
What are common mistakes with "From"?Which "From" sentences look correct but are wrong?
×I bought it from the store for $10.
✓I bought it at the store for $10.
使用 "from" 表示來源或起點，但談論購買地點時，通常用 "at" 或 "in"。"from" 更強調從某處取得物品，而非交易發生的地點。
×He is coming from home.
✓He is coming from his house. / He is coming from home.
"from home" 在某些語境下是正確的（如遠端工作），但當具體指涉「從他的住處出發」時，使用 "from his house/apartment" 更自然。"from home" 常與抽象概念（如感覺、工作模式）連用。
×The movie starts from 7 PM.
✓The movie starts at 7 PM.
表示事件開始的具體時間點，應使用 "at"。"from" 用於表示時間段的起點，通常與 "to" 或 "until" 連用，表示一個時間範圍。
×I prevented him from to go out.
✓I prevented him from going out.
動詞 "prevent" 的固定搭配是 "prevent someone from doing something"，介系詞 "from" 後面必須接動名詞 (V-ing)，而非不定詞。
×This is different from that one.
✓This is different from that one. / This is different to that one. (英式) / This is different than that one. (美式)
"different from" 是最通用且被廣泛接受的用法。學習者常誤以為只有一種說法，但在不同英語變體中，"different to" (英式) 和 "different than" (美式，尤其接子句時) 也正確。關鍵是避免混用或創造不存在的搭配。
×I will study abroad from next year.
✓I will study abroad starting next year. / I will study abroad from next year onwards.
單獨使用 "from" 加時間點來表示未來動作的開始不夠完整，聽起來不自然。應使用 "starting"、"from...onwards"、或 "beginning" 來使語意更清晰。
