時間副詞
時間副詞會透露某個動作發生的時間、持續多久、頻率多寡。
透露何時發生的副詞
這類時間副詞一般會放在句尾。
舉例
- Goldilocks went to the Bears' house yesterday.
- I'm going to tidy my room tomorrow.
- I saw Sally today.
- I will call you later.
- I have to leave now.
- I saw that movie last year.
把這類時間副詞放在句尾，屬於中立的作法；但這些副詞也可以放在其他位置，只是強調的事情會不太一樣。如果把這類副詞放在句首，則是強調時間的要素。在正式書寫上，有些時間副詞也可以放在主要動詞前，而其他時間副詞則不能放在這個位置。
舉例
- Later Goldilocks ate some porridge.（時間很重要）
- Goldilocks later ate some porridge.（這種寫法較正式，類似警察做的筆錄）
- Goldilocks ate some porridge later.（中立的寫法，沒有特別強調哪個字）
透露持續時間的副詞
這類副詞通常會放在句尾。
舉例
- She stayed in the Bears' house all day.
- My mother lived in France for a year.
- I have been going to this school since 1996.
在這類副詞片語中，for 的後面一律接一段時間；而 since 後面一律接一個時間點。
舉例
- I stayed in Switzerland for three days.
- I am going on vacation for a week.
- I have been riding horses for several years.
- The French monarchy lasted for several centuries.
- I have not seen you since Monday.
- Jim has been working here since 1997.
- There has not been a more exciting discovery since last century.
透露頻率多寡的副詞
這類副詞透露某個動作發生的頻率，一般放在主要動詞前，或是助動詞（如 be、have、may、must 等）之後。唯一的例外，就是當主要動詞為 Be 動詞時，副詞才會接在主要動詞後。
舉例
- I often eat vegetarian food.
- He never drinks milk.
- You must always fasten your seat belt.
- I am seldom late.
- He rarely lies.
這類副詞有些可放在句首或句尾，有些則不行。當這些副詞被放在句首或句尾時，副詞的意思就會顯得更強烈。
| 可用於兩種位置的副詞 | 意思顯得較強烈的位置 | 意思顯得較弱的位置 |
|---|---|---|
| frequently | I visit France frequently. | I frequently visit France. |
| generally | Generally, I don't like spicy foods. | I generally don't like spicy foods. |
| normally | I listen to classical music normally. | I normally listen to classical music. |
| occasionally | I go to the opera occasionally. | I occasionally go to the opera. |
| often | Often, I jog in the morning. | I often jog in the morning. |
| regularly | I come to this museum regularly. | I regularly come to this museum. |
| sometimes | I get up very early sometimes. | I sometimes get up very early. |
| usually | I enjoy being with children usually. | I usually enjoy being with children. |
有些頻率副詞則表達動作發生的確切次數，這些副詞通常會放在句尾。
舉例
- This magazine is published monthly.
- He visits his mother once a week.
- I work five days a week.
- I saw the movie seven times.
yet 的用法
yet 用在問句或否定句，放在 not 的後面，則表示某件事尚未發生；而放在問句的句尾，則是詢問某件可能還沒發生、卻期待發生的事。
舉例
- Have you finished your work yet? (= 單純詢問資訊)
- No, not yet. (= 單純否定答句)
- They haven't met him yet. (= 單純否定陳述句)
- Haven't you finished yet? (= 表達驚訝)
still 的用法
still 表達的是持續性。在肯定句中，still 會放在主要動詞前，或是 be、have、might、will 等助動詞後。但如果主要動詞是 Be 動詞，則將 still 放在助動詞後。在問句中，still 就要放在主要動詞前。
舉例
- She is still waiting for you.
- Jim might still want some.
- Do you still work for the BBC?
- Are you still here?
- I am still hungry.
時間副詞的順序
如果要在一個句子中使用多個時間副詞，就使用此順序：
1: 多久 2: 頻率 3: 何時
舉例
- 1 + 2 : I work (1) for five hours (2) every day
- 2 + 3 : The magazine was published (2) weekly (3) last year.
- 1 + 3 : I was abroad (1) for two months (3) last year.
- 1 + 2 + 3 : She worked in a hospital (1) for two days (2) every week (3) last year.
