一、頻度副詞的概念與用法
頻度副詞是指表示動作發生的次數副詞，常見有的never, seldom, sometimes, frequently, often, usually, always 等。頻度副詞通常位于實義動詞之前，動詞be、助動詞、情態動詞等之后。如：
We often get together. 我們常常聚會。
Jane usually goes to work by bike. 簡通常騎自行車上班。
He sometimes goes there on business. 他有時到那里出差。
He can never understand. 他永遠也不會明白的。
I was never very good at maths. 我的數學從來不好。
I shall always remember this. 我將永遠記住這一點。
You have often been told not to do that. 多次告誡過你別干那事。
注：如果有兩個助動詞，頻度副詞通常放在第一個助動詞后面。如：
We have never been invited to one of their parties. 他們聚會，一次也沒邀請過我們。
She must sometimes have wanted to run away. 她有時候一定想到過要逃走。
二、頻度副詞位于助動詞之前兩種情況
1. 為了表示強調，頻度副詞有時也可位于動詞be、助動詞、情態動詞之前；此時助動詞等應重讀。如：
She always was late. 她老是遲到。
I never can remember. 我永遠也記不住。
She hardly ever has met him. 她幾乎從來沒有遇見過他。
He never should have joined the army. 他根本不應當參軍。
2. 在簡略答語中，當頻度副詞與動詞be、助動詞或情態動詞位于句末時，頻度副詞必須前置。如：
“Philip is late again.” “Yes, he always is.”“菲利普又遲到了。”“是的，他總是遲到�！�
“Can you park your car near the shops?” “Yes. I usually can.” “你可以在商店附近停車嗎?”“是的，通常可以�！�
I know I should take exercise, but I never do. 我知道我應該進行體育鍛煉，但我從來沒這樣做過。
