Lesson content
Read, practise, then check your understanding
Form it with have/has plus the past participle. The present perfect links prior events to now: experience at unspecified time, a current result, or activity within unfinished time. Use simple past with a finished past time such as yesterday.
Patterns and examples
- I have visited Delhi twice.
- She has lost her keys, so she cannot enter.
- We have worked here since 2022.
Notice how form and meaning work together. Read examples aloud, identify the controlling word or clause, and compare them with nearby alternatives before applying the pattern in new writing.
Practice sentences
- Choose: I have seen/saw him yesterday.
- Write sentences with since and for.
After answering, explain the rule in your own words and create one original sentence using the same structure.
