There are several recent activity blocks but most do not have snippets of recent posts. The only block I know of that has snippets of recent posts in it's Recent Activity block is a block in Widget Collection available by lms. The problem I have with this block though is that it does not include Post Ratings and the text is blurry for some reason. When someone has rated a post it shows up empty. So I would basically be paying you to create the same widget, but it must show Post Ratings as well instead of an empty block as you can see in these screenshots and it must include a snippet of the recent post.
