For English learners in Taiwan, we generally have started to learn English in junior high school, some of them maybe even started earlier since sending children to bilingual school or cram school are quite popular in Taiwan. However, despite many years of learning experience in English, lots of learners still struggle with it. Hence, this study intends to find the more effective way to learn English by examine the relationship between three variables, which are English learning motivation, English proficiency and English learning system usage by examining how English learning motivation can facilitate learners in Taiwan master this language. Also, exploring whether English learning system usage can moderate the outcome between English learning motivation and English proficiency. Descriptive analysis, reliability analysis, correlation analysis and multiple linear regression were used in this study, the results indicated that English learning motivation and English learning system usage do have relationships with English proficiency. However, English learning system usage does not have the moderating effect between English learning motivation and English proficiency in the study.
