由于样本容量较小，且研究时间跨度较短，导致最终提出的建议仅局限于短期层

Due to the small sample size and short research time span, the final recommendations are limited to the short-term level, and cannot explain the impact of long-term autonomous English learning on English performance or English ability. In the follow-up research, more attention should be paid to the selection of samples. The appropriate sample size is the premise. Second, the research span can be extended to one year or longer. Finally, the object of this study is limited to students. Later, we can increase interviews with parents and teachers to fully understand the characteristics of students' self-directed learning process, and finally put forward more and more constructive suggestions for the study.

Due to the small sample size and the short duration of the study, the final recommendations were limited to the short-term level, which did not explain the impact of long-term English self-learning on English scores or English proficiency. In subsequent studies, more emphasis should be placed on the selection of samples, with the appropriate sample size as a prerequisite, and secondly, the study span can be extended to one year or more. Finally, the object of this study is limited to students, later can increase the interview with parents and teachers, a comprehensive understanding of the characteristics of students in the process of self-learning style, and finally for the study to put forward more and more constructive suggestions.

Due to the small sample size and short research time span, the final suggestions are limited to the short-term level, which can not explain the impact of long-term autonomous learning on English achievement or English ability. In the follow-up study, we should pay more attention to the selection of samples. The appropriate sample size is the premise. Secondly, the research span can be extended to one year or longer. Finally, the object of this study is only limited to students. In the later stage, we can increase interviews with parents and teachers to fully understand the characteristics and styles of students' autonomous learning process, and finally put forward more constructive suggestions for the study.<br>
