In my blog "www.novidadestecnologicas.blog.br ". Why does my homepage posts appear in list form? I would like they  appear with the posts with their images and their summaries. How to do that?

The photo refers to the page as it appears . But I would like to change to posts with their images and their summaries, like you can  see on the following link When I choose posts by month: http://www.novidadestecnologicas.blog.br/blog/index.php?month=201906

Wy does it happens?

Thank you.
