Just couldn't sleep well!!

          Yesterday I slept at 11 o' clock and then it was too hot in my room that I woke up at 3:30 am in the morning and couldn't go back to sleep again. I try to get an eight hour sleep or at least six hours sleep every day, but I couldn't do so because of this hot weather. It makes me feel sick. When can I get a good sleep?? I guess I won't get any good sleep until this year second semester end. Why is it that our dormitory doesn't have elevator and air conditioner in the room? Without good sleep, how can students attend class well?? Most students will doze off to sleep in class because they didn't sleep well, I do doze off to sleep in some class when I am really dead tired. Hope the university's management will look into all these problems and help solve it. For me, it's really tiring and painful to attend class without a good sleep.
