频度副词何时可位于助动词之前
 
一、频度副词的概念与用法
频度副词是指表示动作发生的次数副词,常见有的never, seldom, sometimes, frequently, often, usually, always 等。频度副词通常位于实义动词之前,动词be、助动词、情态动词等之后。如:http://yingyu.chazidian.com
We often get together. 我们常常聚会。
Jane usually goes to work by bike. 简通常骑自行车上班。
He sometimes goes there on business. 他有时到那里出差。
He can never understand. 他永远也不会明白的。
I was never very good at maths. 我的数学从来不好。
I shall always remember this. 我将永远记住这一点。
You have often been told not to do that. 多次告诫过你别干那事。
注:如果有两个助动词,频度副词通常放在第一个助动词后面。如:
We have never been invited to one of their parties. 他们聚会,一次也没邀请过我们。
She must sometimes have wanted to run away. 她有时候一定想到过要逃走。
二、频度副词位于助动词之前两种情况
1. 为了表示强调,频度副词有时也可位于动词be、助动词、情态动词之前;此时助动词等应重读。如:
She always was late. 她老是迟到。
I never can remember. 我永远也记不住。
She hardly ever has met him. 她几乎从来没有遇见过他。
He never should have joined the army. 他根本不应当参军。
2. 在简略答语中,当频度副词与动词be、助动词或情态动词位于句末时,频度副词必须前置。如:
“Philip is late again.” “Yes, he always is.”“菲利普又迟到了。”“是的,他总是迟到。”
“Can you park your car near the shops?” “Yes. I usually can.” “你可以在商店附近停车吗?”“是的,通常可以。”
I know I should take exercise, but I never do. 我知道我应该进行体育锻炼,但我从来没这样做过。
