1.Happiness is to hear sweet voice which is like that a robin sings around the happy flowers,which makes me enjoy myself.
2.Happiness is like that you play on a swing,the swing will take you across the big wall and let you see the big world.
3.Happiness is when people is in trouble,there is someone staying with and comforting you.
上面几句我稍微修饰了一下.至于造句,每个人的风格不一样,还是你想好了,我帮你翻吧.
想好了,追问我就可以了
