1. Basic Form of the Present Perfect

The basic structure of the present perfect is have / has + p.p. It is used when an event that occurred in the past has an influence on the present. Let’s review this with some examples I created myself!!

Closing

This time, I practiced by creating example sentences for the content covered in units 7 and 8.

There were many sentences that I had to correct due to grammatical errors, and sometimes I couldn't write the sentences exactly as I intended in my head. However, as I have been practicing by creating my own examples several times, I now feel more confident in constructing sentences, even if I still make minor mistakes.

I hope you will also practice creating your own sentences like I did, so that you can become more confident in your writing.

Good luck with your studies, and I'll see you in the next post!
