Preview of articles with links

Hello ! I'm still working on the www.spff.ch website. The landing page displays the articles. I put an article "article test" : - the text is a "lorem ipsum" with 5 paragraphs - the second paragraph is composed of 2 words "Lorem ipsum" with a link On the landing page, the paragraphs are grouped and the link is not active. I have to click on "Continuer la lecture" to get the full article, with the active link. How can I configure this to have at least the 2 or 3 first paragraphs and (most important) the link? Thanks for your precious help! Marc
