备  注：Abstract: In this talk, at first I will give a brief description of Grothendieck’s pure motives and Murre's famous four conjectures on Chow groups. Then, I will present our results on these conjectures. More precisely, we consider such a problem: if Murre’s conjectures are true for a variety $X$, when they are also true for the product of $X$ with a curve or some other variety ? Our main results generalize Murre's previous discussion and as consequences, we prove that Murre's conjecture (B) is true for two new kinds of fourfolds. This is a joint work with Xu Ze.
