My fantasy my coming every day all is a clear and boundless sky , remotest places thinks of lollipop kind of seven colored beautiful rainbow being hanging forever; Local working in me is full of laughter , is conducting till very far very distant place; While I recall past events to school, can hear bright reading a book; The fragrance being multicolored fragrance , the earth , for a short time careless fragrance assailing the nostrils but coming while I return to hometown; Solidity having seen multicolored tenderness and beauy , the earth , for a short time careless indomitableness; More important be cheering and laughing of the children!

我幻想我的未来每天都是晴空万里，天边永远挂着想棒棒糖一样美丽七彩的彩虹；在我工作的地方充满着笑声，一直传到很远很远的地方；当我到学校回想往事的时候，可以听见朗朗的读书声；当我回到故乡的时候扑鼻而来的是花的香气、大地的香气、小草的香气；看到了花的娇艳、大地的坚实，小草的顽强；更重要的是孩子们的欢声笑语！
