Tracking galaxies’ evolution by studying the relation between their AGN activity and recent star-formation(RSF) history is one of hot topics of modern astronomy. With the advent of GALEX UV observations, we may have much more accurate information than ever about RSF histories of early-type galaxies in the local Universe. Benefiting from the UV data of 30,000 morphologically-selected early-type galaxies, we have identified three otherwise unrecognizable RSF modes of early-types: Galaxies (a) in a quiescent mode (no UV, no Hα), (b) in a post-SF mode (UV, no Hα), and (c) in an ongoing starburst mode (UV, strong Hα). In this poster, we present a preliminary yet interesting result on the possible evolutionary connection between the AGN activities and the RSF histories of early-type galaxies.
