Avoid duplicate content in my Blog site

Hi there,

I do have a question regarding to SEO guidelines.

I have un blog part in my website which is made with on the top the last article resume and on the bottom 6 articles resume.

When I go to the next article I create a new page with the same top.

Some SEO tools warning me with duplicate content.

Do you know a tips to hide the top article on the next page (2, 3…)

Thank you for you advice
Gwen
