A good student always has high scores．Our duty is to study well．However, some top students are not polite, and I don't consider them good students．

　　As for movie characters, I think Hermione in Harry Potter is a standard good student．She is top at school, and is clever, kind and brave．

　　A good student has a clear goal to achieve and never gives up．For example, our monitor is always concentrating(专心)in class．He doesn't care that we laugh at his silly gestures while he is trying to learn something by heart．In the latest exam he did best in our grade!

　　In my opinion, he or she who likes studying is a good student．They may not do well in exams, but they are always working hard and trying to improve．

　　I think Thomas Edison was a good student．He must have been bad in his teachers' eyes because he didn't get good school reports．But he became a great inventor at last．

　　High scores do not mean anything．There is a student in our school who always scores high in exams．Maybe he is a good student in his teachers' eyes．But I dislike him because he doesn't know how to care for others．I think a good student is always ready to help, and he should be one whom your classmates feel comfortable to be with．
