回答“多麽經常”這樣問題的時間副詞通常被稱為頻度副詞。常見的這類副詞有：always, often, usually, sometimes, occasionally, seldom, never, generally, frequently, hardly, ever, constantly, continually, rarely, scarcely等。
二、頻度副詞在句中的位置
頻度副詞常用在句中，其位置與有無助動詞有關。句中無助動詞或情態動詞時，位於動詞be之後，其他動詞之前，如：
She is sometimes late.
She sometimes comes late.
We occasionally saw him walking along the river bank.
Films like this rarely reach the big screen.
動詞帶有壹個或壹個以上的助動詞或情態動詞時，位於第壹個助動詞或情態動詞之後，如：
She has sometimes been coming late.
Do you often hold such parties?
He has never been late.
It has occasionally been done.
An Lee has never directed a martial arts film before.
註意：(1)句中副詞如移至助動詞之前則是為了強調緊跟在其後的助動詞。如：
He never has been and never will be successful.
他現在和以後都不會成功。(強調助動詞has和will)
You always were generous. 妳總是很慷慨。
(2) 有些頻度副詞的位置比較靈活，如：sometimes, often等，還可以位於句首或句末。
1)在句首，即在主語前，這是最強調的位置，如：
Sometimes she comes late.
2)在句末，在動詞及賓語或補足語之後。這個位置的強調性弱於句首但強於句中。如：
She comes late sometimes.
三、什麽是地點副詞
表示地點的副詞和表示位置關系的副詞統稱為地點副詞。常見的這類副詞有：
表示地點的：here, there, home, upstairs, downstairs, anywhere, everywhere, nowhere, somewhere, abroad, elsewhere等。
表示位置關系的：above, below, down, up, out, in, across, back, along, over, round, around, away, near, off, on, inside, outside, past等。
在表示位置關系的副詞中，有些副詞也可用作介詞(如：above, over, beyond, around, below, down, up, in, along, near, off, on, past等),在沒有賓語時就是副詞，有賓語時就是介詞，如：
Come in, please. (副詞)
They live in the next room. (介詞)
Let's take along. (副詞)
Let's walk along this street. (介詞)
She looked around. (副詞)
They sat around the table. (介詞)
Let's go on with the work... (副詞)
What subject will you speak on? (介詞)
四、地點副詞在句中的位置
地點副詞常放在動詞後面，如果是及物動詞，壹般就放在賓語後面。如：I remember having seen him somewhere.
Wuxia films are popular in China.
地點副詞和時間副詞並列使用時，壹般要把地點副詞放在時間副詞之前。如：
We had a meeting here yesterday.
He did the work carefully here yesterday.
如果地點狀語很長時，也可以放在時間狀語之後。如：
He was born in 1940 in a small village at the foot of Mount Tai.
五、地點副詞常可以用作表語
副詞可以用作表語，主要是地點副詞，時間副詞和其他副詞有時也可以用作表語。如：
They are inside. 他們在裏面。
How long will she be away? 她要離開多久？
When will you be back? 妳什麽時候回來？
You haven't been around much. 妳很少到這邊來。
He'll be round in an hour. 他壹個小時內就到。
Now autumn is in. 秋天來了。
I must be off now. 我得走了。
We are behind in our plan. 我們落在計劃後面了。
