It is maintained that one of the significant determining issues of success is motivation, and enhancing EFL/ESL students' motivation is dominant in cultivating their learning in the classroom. Moreover, teachers are reflected as the most noteworthy figure of any scholastic organization and the positive rapport between students and teachers is significant for learners' state motivation. In line with the investigations of teacher-student rapport, principles from positive psychology (PP), and motivational theories such as self-determination and rhetorical/relational goal theory, the present theoretical review seeks this type of relationship and its effects on learners' motivation. Student-teacher rapport results in progressive practices for learners, as well as superior classroom involvement, and motivation. Subsequently, the helpfulness of findings for teachers, learners, materials developers, and teacher trainers are conferred.

Learning motivation is closely related to second language acquisition. Strong learning motivation can make up for the lack of language competence and poor learning conditions to a certain extent, while lack of motivation or demotivation will hinder language-gifted learners from achieving their expected learning goals. This study investigates the demotivating factors of learning English among non-English majors in medical university by interviewing 60 undergraduates. The findings show that the demotivating factors mainly involve the teachers, teaching contents, learning environment and the learners. The study further puts forwards some practical suggestions for stimulating and maintaining students’ learning motivation.

Learning motivation has been considered as a determining factor in foreign language learning.The decreasing of learning motivation will bring negative impact on students' foreign language learning and teachers' foreign language teaching. In recent years, many researchers have done some empirical studies on learning demotivation among elementary students, middle school students and non-English major college students. This paper attempts to sort out the literature on the decline of foreign language learning motivation and find out the research gap, hoping to inspire relevant researches in the future.
