Poles and Zeros Physical meaning


We obtain the pole and zero from the transfer function of a circuit.And many tutors said that the gain begin to rise at 20db/decade above a zero,and fall off at a pole.
I don't know why this occurs.How to relate the pole and zero to the physical circuit? Anyone can show me some meterials about this?
