Equivalence Principles, Lense-Thirring Effects, and Solar-System Tests   of Cosmological Models
  In this talk, we review the empirical status for modern gravitational theories with emphases on (i) Equivalence Principles; (ii) Lense-Thirring effects and the implications of Gravity Probe B experiment; (iii) Solar-System Tests of Cosmological Models.
