结束了长期分裂局面，是中国重新统一的朝代是（   ）

    My new Chinese teacher is Miss White. She is funny and kind. Her favourite food is salad because it is fresh and healthy. She can sing English songs and play the guitar. There is a lake in front of her house. Behind the house, there is a mountain. So she often climbs the mountain and plays some sports on the weekend. I like my Chinese teacher.
