5 . I rise in the east, and it is day. I send my light into your room, and tell you it is time to get up. When I shine, you can not lie in bed or sleep. You must work and study.
I send my light here and there. I shine over the trees, the houses, the hills and the water, and I make everything beautiful.
I am high up in the sky, higher than the highest mountains, higher than the clouds. Sometimes I hide(藏)my face behind a thick cloud, and you cannot see me. But when there are no clouds and the sky is blue, and when I shine at noon, you can not look at me, because I am too bright.
