always, usually, often, sometimes, seldom, never 有甚麼分別???

always: do 7 times in a week

usually: do 5-6 times in a week

often: do 3-4 times in a week

sometimes: do 2 times in a week

seldom: do 1-2 times in a week

never: do 0 time in a week

(1) always (2) usually (3) often (4) sometimes (5) seldom (6) never
都是是英語中常用的adverbs of frequency。


除了字義上的分別，它們主要不同之處有以下幾點:
1. 在句子中的位置，例如開頭、結尾
2. 提問時 (question form) 的用法
3. 否定時 (negative form) 的用法

在一些早期的英文教科書中，這些adverbs of frequency 會被列表如下。
在最上方的表示 frequency最多的事情(一定做), 在最下方的表示frequency最低的(絕不會做)。


紅字是題目中的例子，為方便說明， 加入綠色其他字例。

Seldom
Rarely
Never


100% of the time (有一定 做/進行 的意思)
about 90% of the time
about 80% of the time
about 70% of the time
about 50% of the time
about 40% of the time
about 20% of the time
about 10% of the time
about 0% of the time

例句: (字義上的分別)
I always brush my teeth before I go to bed. (=every night, ∴100% of time)
I frequently watch the news before dinner. (=happens most days)
I usually have toast for breakfast. (=it is common )
I often go to the park with my dog. (=many times,)
I sometimes see him on the way to school. (=at particular occasions but not all the time)
I occasionally visit the Science Museum. (=not happening often or regularly)
I seldom have a chance to go to the theatre. (=it is not common)
I rarely smoke cigars. (=almost never)
I never work on the weekend. (=not at any time or not on any occasion)

大部分 adverb of frequency 都是放在 subject 和 verb 之間。
例句:
I always help the other students.
My brother usually comes late to school.
Jenny and Susan often study in the library after class.

但當用verb [to be]時 , adverb of frequency 都是放在verb 的後面。
例句:
I am always a good student.
My brother is usually late to school.
She is often ill in winter.

如句子中的 verb 由兩部分組成， adverb of frequency 通常會放在第一部分的後面:
例句:
I can never remember his name.
My father doesn't usually smoke.
The children have often complained about the state of the school toilets.

也可以把adverb of frequency 放在句子的開頭或結尾, 有強調作用。
例句:
We go to school by bus sometimes.

但 [Always] 不能放在句子的開頭或結尾。而 [Never], [seldom], [rarely] 等祇能放在 [polemic statements] 的開頭，更不能放在句子的結尾。
Polemic statements 例句：
Never has there been a better time to overcome our differences!
Rarely do we have an opportunities like this.
Seldom had the orchestra given a worse performance.



提問時 adverb of frequency 要放在 main verb 之前 。
例句：
Do you often go to the cinema?

但 [Never], [seldom], [rarely] 等含否定意思的 adverbs of frequency 一般不會用來提問。(not usually used in the question form.)
如句子是否定式，adverb of frequence 要放在 main verb 之前。
例句：
They do not often go to the cinema.

但 [Never], [seldom], [rarely] 等含否定意思的adverbs of frequency 一般不會用在否定式句子。(not usually used in the negative form.)
