Motivating English as a foreign language (EFL) students to read in English extensively can be a difficult task. EFL educators often use a wide range of methodologies to encourage their students to continue reading. Many of them also seek ways to motivate their students to engage in extensive reading (ER) autonomously. This paper presents a study of a private Japanese university’s ER program which uses graded readers through a mobile library cart system as well as a main library. The study utilized 2,075 student reading records and a survey of 755 Japanese EFL students in 75 required 1 and 2 year EFL classes to better understand how the main and mobile libraries affected student ER. Results indicate that the main library plays an important role in the ER program by making students responsible for their own learning and initiative. However, the mobile library proves to be more successful at getting students to engage in ER and develop autonomous reading skills.

辅助功能和自主阅读的促进

激发英语作为外语（EFL）的学生广泛阅读英语可能是一项艰巨的任务。EFL教育者经常使用多种方法来鼓励学生继续阅读。他们中的许多人还寻求各种方法来激发学生自主参与广泛阅读（ER）的能力。本文介绍了对日本一所私立大学的ER计划的研究，该计划通过移动图书馆购物车系统和主图书馆使用分级阅读器。该研究利用了2,075名学生的阅读记录，并对75名需要1年和2年EFL课程的755名日本EFL学生进行了调查，以更好地了解主要图书馆和流动图书馆如何影响学生的ER。结果表明，主图书馆通过使学生对自己的学习和主动性负责，在ER计划中发挥了重要作用。然而，
