2. Grammar Focus
Grammar Point 1: Present Perfect Tense
Used for actions that happened at an unspecified time in the past or actions that continue to the present. The exact time is not important; the focus is on the experience or the result.
Key Examples:
- I have visited the zoo many times.
- She has lost her house keys.
- They have lived in this city for ten years.
Grammar Point 2: Present Perfect with Already and Yet
Use ‘already’ for actions that happened sooner than expected (usually in affirmative sentences). Use ‘yet’ for actions you expect to happen soon (strictly in negative sentences and questions).
Key Examples:
- We have already seen this new movie.
- My brother has not cleaned his room yet.
