Thank special brain, let me come here to study brain development courses, this study makes me understand a lot of truth, such as before, I do not take the time to develop my own brain consciousness, and when I encounter problems, my first thought is to ask parents or my teachers for answer,and  in the end simply lazy people think, after having studied here, just know originally the brain thinking is not very boring. On the contrary I also learned a lot of new knowledge, thanks to our parents for my education, takes good care to thank mom and dad for me, thanks to the teaching assistant teacher, let me spend a happy holiday!
