In English teaching, it is necessary to pay attention to students' psychology and cognition in order to make them harmonious and effective. Therefore, English teacher would change their teaching opinions, realizing teaching object, guiding student's minds and ideas to study by some measures, such as accordant teaching and study, making students as a base in study, and students' self-study. In other words, making student study actively rather than passively is much better for their English abilities.
