頻率副詞用法全解
頻率副詞專門用來回答「多常 (How often)?」這個問題。它們為「現在簡單式」所描述的習慣與事實「上色」，標示出動作發生的「頻繁程度」。
認識頻率的光譜
我們可以將頻率副詞想像成一個從「總是發生」到「從不發生」的連續光譜。
| 頻率副詞 | 頻率 (約略) | 中文 | 範例 |
|---|---|---|---|
| always | 100% | 總是 | He always drinks coffee. |
| usually | 80-90% | 通常 | I usually walk to work. |
| often | 60-70% | 常常 | They often watch movies. |
| sometimes | 30-50% | 有時候 | She sometimes feels tired. |
| seldom / rarely | 10-20% | 很少 | He seldom goes to the movies. |
| never | 0% | 從不 | We never eat fast food. |
語法焦點: seldom (很少) 和 never (從不) 本身帶有否定含義, 句子不需再加 not。
黃金定位規則
將頻率副詞放在句子的正確位置至關重要。其位置完全取決於句子中使用的是「Be 動詞」還是「一般動詞」。口訣:「一般動前, Be 動後」。
規則 A: 放在「一般動詞」之前
主詞 + 頻率副詞 + 一般動詞...
- I always get up early.
- She usually reads books.
規則 B: 放在「Be 動詞」之後
主詞 + Be 動詞 + 頻率副詞...
- He is always happy.
- You are often late.
如何詢問頻率: How often...?
若要詢問別人做某件事的頻率, 我們使用 How often...? 來開頭。
句型: How often + do/does/is/are + 主詞 + ...?
- Q: How often do you go swimming?
A: I sometimes go swimming. - Q: How often is she busy?
A: She is usually busy.
