五花山

    小朋友，你们说山是什么颜色的？

我家就住在大山里，我知道山是什么颜色的。

    春天的山是绿色的，可那绿是浅浅的，许多树叶儿冒出芽来，嘴上还带着嫩嫩的黄色呢。

    夏天的山也是绿色的，可那绿是深深的，一片片树叶，不管是大的还是小的，都像被绿色的蜡笔涂了，连雨点落上去，都给染绿了。

    秋天的山呀，可不再是一个颜色了。下了一场秋霜后，你看吧：有的树叶变成了金黄色，好像所有的阳光都照到那里去去了；有的树叶变成了杏黄色，远远看去，就像枝头挂满了熟透的杏和梨；有的树叶变成了火红色，风一吹，树叶跳起舞来，就像一簇簇火苗在跳跃；还有的树叶变得紫红紫红，那颜色就像剧场里的大幕布。只有松树不怕秋霜，针样的叶儿还是那样翠绿翠绿的。

    秋天的山就是这样五颜六色。一层金黄，一层翠绿，一层火红„„人们给五颜六色的山起了个名字，叫“五花山”。
