But sometimes we can't sleep too much time .Why ?Because sometimes we have too much homework or we have any important things to do .So somebody only can sleep 5~6 hours ,but it's really not enough .
And sometimes we must get up ,now l'm boarder l want have more sleep ,schoo just beside this buliding ,and we never late for class (no one time) Why can't let us sleep more times ,if we're not late for class that's ok ,and every day we eat breakfast .
Sometimes it's very cold or the light is on ,we can't get up soon .So l think if we can have enough sleep everything will be better .
