1. 细节理解题：根据第一段"People start this study on March 12 and finish it on March 26"可知研究从3月12日到3月26日，共14天，也就是半个月，对应选项B。
2. 细节理解题：根据第二段"And more and more college students use their mobile phones just before they sleep and the percentage is even higher"，结合前文71%的学生在21点到午夜使用手机，可知大学生使用手机最多的时段是睡前，对应选项C。
3. 词义猜测题：后文提到男生用手机放松的占比更高，女生用手机网购的占比更高，说明男女生使用手机的情况不一样，因此"difference"的中文含义是“差异”，对应选项A。
4. 数字计算题：文中提到参与研究的男生共590人，其中66%的男生用手机放松，计算可得590×66%≈390，对应选项B。
5. 主旨大意题：文章介绍了相关研究，分别说明了大学生使用手机的时长、常用时段、不同性别的使用方式，以及手机对学习的帮助，目的是告诉读者大学生什么时候、如何使用手机，B选项的“喜欢用手机的原因”文中没有重点阐述，C选项只覆盖了文章一小部分内容，过于片面，对应选项A。
