Teaching of English Writing for Ph.D. Graduates Based on Output-Driven Hypothesis

The theory of output-driven hypothesis is especially appropriate for second language teaching, because language needs practicing. The teachers of Ph.D. graduates’ English writing should reform the former curriculum system, and through assigning interesting writing tasks, optimizing the content of writing instruction, discussing for writing input, providing writing feedbacks, and establishing a comprehensive evaluation system, their writing ability is sure to be enhanced.
