認識頻率副詞 (always, usually, often, sometimes, never)

要表達做某件事的「頻率」或「頻繁程度」，我們就需要用到「頻率副詞」(Adverbs of Frequency)。這篇就來認識最常見的五個頻率副詞！

一、認識常見的頻率副詞 (Common Adverbs of Frequency)

這些副詞告訴我們一件事情「多常」發生。以下是從最頻繁到最不頻繁的順序：

• always (總是；一直): 表示百分之百都會發生。
  例：He always drinks coffee in the morning. (他早上總是喝咖啡。)
• usually (通常): 表示很常發生，大概 80-90% 的機率。
  例：I usually walk to work. (我通常走路去上班。)
• often (常常): 表示蠻常發生的，大概 60-70% 的機率。
  例：They often watch movies on weekends. (他們週末常常看電影。)
• sometimes (有時候): 表示偶爾發生，大概 30-50% 的機率。
  例：She sometimes feels tired after lunch. (她有時候午餐後覺得累。)
• seldom (很少；不常): 表示發生的頻率很低，大概 10-20% 的機率。 (與 rarely 意思相近)
  例：He seldom goes to the movies alone. (他很少自己去看電影。)
• never (從不): 表示完全不會發生，百分之零。
  例：We never eat fast food. (我們從不吃速食。)

(注意：seldom 和 never 本身帶有否定意思，所以句子中不需要再加 not 或 don't/doesn't)

二、頻率副詞放哪裡？(Position of Frequency Adverbs)

把頻率副詞放在句子中正確的位置非常重要！主要有兩個規則：

規則 1：放在「一般動詞」前面

如果句子裡用的是像 eat, play, study, walk 這樣的一般動詞，頻率副詞要放在動詞的**前面**。

句型： 主詞 + **頻率副詞** + 一般動詞 + ...

• I always get up early.
• She usually reads books before bed.
• He seldom complains.

規則 2：放在「Be 動詞」後面

如果句子裡用的是 Be 動詞 (am, is, are)，頻率副詞要放在 Be 動詞的**後面**。

句型： 主詞 + Be 動詞 (am/is/are) + **頻率副詞** + ...

• He is always happy.
• You are often late for class.
• I am never bored at home.

三、如何問頻率？(Asking about Frequency)

想問別人「多常」做某件事，可以用 How often...? 來開頭。

• Q: How often do you go swimming? (你多常去游泳？)
  A: I sometimes go swimming. (我有時候去游泳。)
• Q: How often is she busy? (她多常很忙？)
  A: She is usually busy. (她通常很忙。)
• Q: How often does he visit his grandparents? (他多常去探望祖父母？)
  A: He seldom visits them. (他很少去探望他們。)

練習 1：根據描述，選擇最適合的頻率副詞

1. Mary eats vegetables every day. She _______ eats vegetables. (A. sometimes / B. always / C. never)
2. John doesn't like coffee at all. He _______ drinks coffee. (A. never / B. often / C. usually)
3. We go to the park maybe two or three times a week. We _______ go to the park. (A. always / B. sometimes / C. often)
4. My dad only works on weekdays, maybe once or twice a year he needs to work on Saturday. He _______ works on Saturdays. (A. usually / B. seldom / C. never)

解答：1. B 2. A 3. C 4. B

練習 2：將括號中的頻率副詞放入句子正確的位置

1. I drink tea. (usually) →
2. He is tired. (often) →
3. They play outside. (never) →
4. Are you late? (sometimes) →
5. She helps her mom. (seldom) →

解答：1. I usually drink tea. 2. He is often tired. 3. They never play outside. 4. Are you sometimes late? 5. She seldom helps her mom.

頻率副詞小總結：

• 頻率副詞告訴我們事情發生的頻繁程度 (always > usually > often > sometimes > seldom > never)。
• **位置規則：** 放在**一般動詞前**，放在**Be 動詞後**。
• 用 How often...? 來詢問頻率。
• 記住這幾個常用副詞和它們的位置，就能更精確地表達你的習慣囉！
