  The standard model of electroweak interactions is reviewed, stressing the top
quark's impact on precision tests and on determination of parameters of the
Cabibbo-Kobayashi-Maskawa (CKM) matrix. Some opportunities for the study of CP
violation in the decays of $b$-flavored mesons are mentioned, and the
possibility of a new ``standard model'' sector involving neutrino masses is
discussed.
