Dedicated students believe they must work hard,and they do work hard; that is to say,they conscientiously carry out all the tasks the teacher sets them and they study their course books or follow their computer programs regularly.

• 致力于学习的学生认为自己必须用功，也确实很用功，换句话说，他们自觉地完成老师布置的所有作业，并按部就班地温习课本或按电脑教学程序操作。
