中文摘要：

以250名四川灾区中学生为被试，考察了性别、年级与学习动机的关系，然后对比2009年与2011年四川灾区学生的学习动机水平，探索时间变量在学习动机水平改变中所起的作用，最后以60名灾区中学生为被试通过实验室实验证明地震所引起的自我控制资源损耗能够解释灾区学生学习动机降低的现象。由此可以解释为，随着时间的逝去，灾区学生的自我控制资源得到了一定程度的恢复，学生对学习的内生动机又重新唤起。

英文摘要：

The present study, by making a survey of 250 secondary school students from the emthquake-hit areas in Sichuan Province, aims to probe into the relationship between gender, grade, and learning motivation. The study, by comparing these students＇ learning motivations in 2009 and 2011, explores the effect of the time variable on the change of learning motivations; a survey of 60 students out of the students surveyed is used to prove that self-controlled resource depletion caused by the earthquake can help explain the reduced learning motivations of the students in earthquake-hit areas. The research results show that, with the passage of time, the students＇ intrinsic learning motivations have been renewed because their self-controlled resources have been recovered to a certain degree.
