定义 / 说明
频率副词表示某事发生的频率。常见词有 always, usually, often, sometimes, 和 never。它们在句中的位置很重要：通常放在实义动词前，但放在 be 后。这条小小的语序规则在日常英语里非常常见。
关键规则
- 与大多数实义动词连用时，副词放动词前：I always eat breakfast.
- 与 be 连用时，副词放 be 后：She is often late.
- 这些副词常与 Present Simple 一起表示习惯。
- never 已经是否定意义，不要再叠加否定。
- 这些副词能让你描述习惯时更自然、更具体。
例句
- I always drink tea in the morning. - 我早上总是喝茶。
- We usually go by bus. - 我们通常坐公交去。
- He often calls his mother. - 他经常给妈妈打电话。
- They sometimes eat out. - 他们有时在外面吃饭。
- She is never late. - 她从不迟到。
- I am usually tired after work. - 我下班后通常很累。
常见错误
- ❌ I drink always tea in the morning. -> ✅ I always drink tea in the morning.
- ❌ She often is late. -> ✅ She is often late.
- ❌ He doesn't never cook. -> ✅ He never cooks.
提示
- 可按从 100% 到 0% 记忆：always -> usually -> often -> sometimes -> never。
