The nature and origin of the Fermi-liquid states in high-Tc superconductor have been studied by angle-resolved photoemission and inverse photoemission spectroscopies on Bi2Sr2Ca1\_xYxCu20a (x=O.O to 0.5). The result shows that impurity-like states or mid-gap states are created in the charge-transfer
