i just found out that the pictures can only be seen on the windows xp system computers. yesterday don was asking me what i think about making students attend class. well, i am a class-skipper. i mean, if i have a good teacher and i am interested in the course, i will work very hard, just like the literature class i have now, but, if i find a class very boring and useless, i will just skip it as long as i can and use the time to learn things i really want to learn. so i skip some " must-taken" classes, but i also go to classes for other students which i probably shouldn't be there since i didn't pay for it. so i would say i hope i can go to any class i want and don't have to attend classed i am not interested in at all. but if i am a teacher, i will also consider should i make the students study. 'cause some students will skip any class they can since they literally don't want study in college. and as a teacher, if i just let them do it, am i being too irresponsible? maybe one day they will regret that they didn't study more in college. i heard in beida you could just go to listen any class you want. but i guess you have to pass those required ones. how about that, as long as you could pass the test, you could either come or not come to the class. well, i should've been in my  advanced listening class now, but i skiped it, agiain :)  i don't think it's not good for everyone, at least i think there is a better way for me to practice my listening.
