bit doing vs bit to do

need to,try to）連用時。 - 在描述過去一次性的具體事件時，兩者常可互換，但 bit doing 可能更強調動作正在進行或持續的畫面。 EN: The puppy loves to bit chewing on my slippers. 翻譯: 這隻小狗很愛咬我的拖鞋。

常見錯誤
What are common mistakes with "Bit"?Which "Bit" sentences look correct but are wrong?
×He bit the apple yesterday.
✓He bit the apple yesterday.
雖然 'bit' 是 'bite' 的過去式，但學習者常誤以為 'bit' 是錯誤的，而想改成 'bited'。'Bite' 的過去式確實是不規則變化的 'bit'，過去分詞則是 'bitten'。
×I have bit my tongue.
✓I have bitten my tongue.
'Bit' 是過去式，用於簡單過去時。在完成時態（have/had + 過去分詞）中，必須使用過去分詞 'bitten'。
×Be careful, the snake bits!
✓Be careful, the snake bites!
'Bit' 僅是過去式。在現在時態中，主語為第三人稱單數時，動詞應使用 'bites'。
×I need a bit for my computer. (想表達『一點點』)
✓I need a bit for my computer. (想表達『一點點』應使用 'a little' 或 'a bit of')
學習者可能混淆動詞的 'bit'（咬）與名詞的 'bit'（位元、一小部分）。想表達『一點點』時，通常說 'a bit of' 或用於副詞片語 'a bit'（例如：a bit tired）。單獨 'a bit' 作名詞指『一小塊』或電腦的『位元』。
×The mosquito bit on my arm.
✓The mosquito bit my arm.
動詞 'bite' 是及物動詞，通常直接接受詞，不需要介系詞 'on'。'Bite' 後面可直接接被咬的物體或人。
