　Abstract

Great progress on Gamma-ray burst (GRB) research has been made since the discovery of afterglows in 1997. Besides that the observations on GRBs are briefly reviewed, this paper focuses on the introduction of recent progress and issues in theories of GRBs, including GRBs themselves, afterglows, energy engines, host galaxies, environments, high energy particles and gravitational radiation, cosmology, etc.
