After the edition, proofreading is the last quality-checking working procedure before printing. To enhance the proofreading efficiency of educational theory periodicals, we should attach importance to the manuscript processing before the proofreading. The first proofreading emphasizes particularly on check up the original manuscript; the second proofreading empha- sizes the elimination of writing mistakes; the third proofreading stresses an overview of the over-all situation; the man-machine u- nion proofreading examines the loss and makes up leaks; and the press proof inspects the overall uniformity. At the same time, the periodical editor must grasp the scientific proofreading methods, intensifies the training of reading a specific point, overcomes the disturbance of the bad psychological factors and alternates work with rest with a good work rhythm.
