What Are Adverbs of Frequency?
Adverbs of frequency are words that describe how often an action happens. They help us talk about routines and habits.
Here are some common adverbs of frequency:
- always (100% of the time)
- usually (about 90% of the time)
- often (about 70% of the time)
- sometimes (about 50% of the time)
- rarely / seldom (about 10% of the time)
- never (0% of the time)
Where Do Adverbs of Frequency Go?
The position of adverbs of frequency in a sentence is very important. There are three main rules to remember:
- Before the main verb: Most adverbs of frequency come before the main verb in a sentence. For example, I always eat breakfast.
- After the verb to be: When the verb is am, is, 或 are, the adverb of frequency comes after it. For example, She is usually late.
- Between an auxiliary verb and the main verb: If there is an auxiliary verb (like do, does, have, can, will) and a main verb, the adverb goes in the middle. For example, They don't often visit.
Special Cases: 'Sometimes' and 'Often'
The adverbs sometimes 和 often are more flexible. They can also appear at the beginning or end of a sentence for emphasis.
- Sometimes I walk to work. (Beginning)
- I walk to work sometimes. (End)
- Often we go to the cinema. (Beginning)
- We go to the cinema often. (End)
However, the most common position for these adverbs still follows the main rules (before the main verb).
Asking About Frequency
To ask how often someone does something, we use the question phrase How often...?
- How often do you exercise?
- How often is she late for class?
You can answer these questions using adverbs of frequency or other time expressions like once a week, every day, 或 twice a month.
| Adverb of Frequency | Approximate Frequency |

| always | 100% |
| usually | 90% |
| often | 70% |
| sometimes | 50% |
| rarely / seldom | 10% |
| never | 0% |

西班牙语母语者常犯的错误
A common mistake for Spanish speakers is placing the adverb 之后 the main verb. In Spanish, adverbs often follow the verb, but in English, they usually come before it.
- 错误： I eat always breakfast.
- 正确： I always eat breakfast.
Another error is using never with a negative verb. Never already means 'not ever', so you don't need another negative word.
- 错误： I don't never go there.
- 正确： I never go there.
