频度副词和频率副词的区别

如题所述

1. 频度副词和频率副词在英语中都用于表示动作的频率,但它们在句中的位置和使用规则上有所不同。
2. 频度副词通常位于系动词、助动词或情态动词之后,行为动词之前。例如:
- 在系动词之后:She is sometimes very busy.(她有时很忙。)
- 在助动词之后:I will never forget this lesson.(我将永远忘不了这一课。)
- 在实义动词之前:We often go there.(我们常去那儿。)
3. 频度副词有时也可以放在句首、句中或句末。例如:
- 句首:Sometimes she writes to me.(她有时候给我写信。)
- 句中:She writes to me sometimes.(她有时候给我写信。)
- 句末:She writes to me often.(她经常给我写信。)
4. 当句子中有两个助动词时,频度副词通常放在第一个助动词之后。例如:
- 两个助动词:We have never been invited to one of their parties.(他们聚会,一次也没邀请过我们。)
- 两个助动词:She must sometimes have wanted to run away.(她有时候一定想到过要逃走。)
5. 在否定句中,频度副词的位置和用法有所不同:
- usually和often可以位于否定词之前或之后:
- They don’t often hold such parties.(他们不常开这样的晚会。)
- They usually don’t get up before nine on Sundays.(星期日我们一般不在9点以前起床。)
- always必须位于否定词之后:
- Things are not always what they seem to be.(外表往往是靠不住的。)
- Silence must not always be read as consent.(沉默并不见得一定意味着同意。)
- sometimes必须位于否定词之前:
- Jim is sometimes not very punctual.(吉姆有时不太准时。)
- Debbie is sometimes not responsible for what she does.(黛比有时不对她所做的事负责任。)
