用法說明
How is "I" different from similar structures?What usage mistakes are common with "I"?
I vs. me
- I 是主格代名詞，在句子中作為主詞，執行動作。
- me 是受格代名詞，在句子中作為受詞，接受動作。
- 在比較結構中（如 than, as...as），正式寫作傾向使用主格 I，但口語中受格 me 也很常見。
- 在複合主詞或受詞中（如 someone and I/me），將另一個人名移除後檢查句子是否通順，是判斷該用 I 還是 me 的簡單方法。 EN: My brother and I went to the store. 翻譯: 我哥哥和我去了商店。
EN:The teacher gave the books to my brother and me.
翻譯:老師把書給了我哥哥和我。
總結建議
記住「I 做動作，me 接受動作」的基本原則，並在複合結構中使用移除法來檢查。
易混淆對比
What is the difference between "I" and similar words?How to choose "I" vs alternatives?

「I」為主格，用於主詞位置；「me」為受格，用於受詞位置。
i vs myself
「I」是主格代名詞；「myself」是反身代名詞，用於強調或當動詞受詞與主詞相同時。
i vs my
「I」是代名詞，指「我」這個人；「my」是所有格代名詞，意為「我的」。
口語用法

引述
在引述自己或他人的話語時，口語中常會重複使用 "I" 來強調發言者。 EN: I was like, "I don't think so," and he just walked away. 翻譯: 我那時就說：「我可不這麼認為。」然後他就直接走開了。
EN:She goes, "I told you I would be late," and I'm like, "I know, I know."
翻譯:她就說：「我告訴過你我會遲到。」然後我就回：「我知道，我知道。」
語氣強調
在口語中，會透過重音或拉長音來強調 "I"，以凸顯個人感受、意見或與他人的對比。 EN: I really wanted to go, but no one asked me. 翻譯: 我真的很想去，但就是沒人問我啊。
EN:I didn't take it! (Someone else did.)
翻譯:我才沒拿呢！（是別人拿的。）
停頓填充
在思考或組織句子時，"I" 有時會與其他填充詞（如 "um", "well"）一起出現，或單獨作為停頓的起點。 EN: I... I'm not sure how to put this. 翻譯: 我…我不太知道該怎麼說。
EN:Well, I mean, I guess we could try.
翻譯:嗯，我的意思是，我想我們可以試試看。
正式書寫注意：在正式寫作（如論文、報告、商業信件）中，應避免上述口語用法。引述應使用標準引述格式，避免 "I was like"；強調應透過選詞與句子結構來達成，而非口語重音；並應刪除所有思考停頓的填充詞，使行文簡潔直接。
