Colin’s cloud

  This topic is very attracted me. Because I usually stay up late for studying. Sometimes I wondered that if we didn’t have enough time to sleep, maybe we will  distract ? And  how long does “enough time” of sleeping  should be define. If I only slept for four hours I would feel just as tired as if I slept for 10 hours So I'd rather just sleep for four hours.  As for whether it will affect the learning effect, so far I don't think it will affect it. I think perseverance is your superpower   

I’m this topic’s presenter. After this presentation, I think I have grown up because I feel  braver than before presentation. Everyone should keep working hard. Don’t stay where you are, we should improve and improve. Do as well as possible.
