早睡 Sleep Early

Recently, I feel tired in the class, because I can’t help playing a new computer game at night. I sleep very late. As a result, I can’t focus my mind on study. I feel really bad and decide to stop sleeping so late. I stop playing the computer game and have enough sleep. Now I feel so good. 
最近，在課堂上我感到很疲憊，因爲我無法控制自己晚上玩一種新的電腦遊戲。我睡得很晚。因此，我不能集中精力學習。我感覺非常糟糕，所以決定不睡那麼晚了。我也不玩電腦遊戲了，保證足夠的睡眠。現在我感覺很好。
