Oral English is always ignored by teaching in senior school.After years of learning,as we all know most students are so called high scores and low abilities,or what they obtain is so-called"mute English".At present,the English teaching in high school mainly emphasis on written examination ability,so the senior student master certain elementary reading,writing and listen ing skills while their speaking competence is poor.The author made some analysis from different aspects of the present situation of senior students and worked out some ways according to the motivation theory in order to arouse students to improve their speaking competence. 展开更多
