Using Time Words with Present Perfect
Time words such as "since," "for," "yet," "never," "ever," and "before" are important in present perfect sentences to indicate the time frame or duration of an action.
Time words are placed differently within the sentence based on their type.
- "Since" indicates the start time.
- "For" indicates the duration.
- "Yet" is often used in questions or negative sentences to suggest that something hasn't happened up to now.
