The topics include the present status of the standard model, Higgs physics, supersymmetry, strongly interacting electroweak symmetry breaking mechanism, and top quark physics.Talk presented at The First ACFA Workshop on Physics/Detector at the Linear Collider, Nov. 26-27, 1998, Tsinghua University, Beijing, China. 35 pages with 3 figures, using epsfig.sty and rotate.styHigh Energy Physics - Phenomenologytext
