　　　最妙的是下点小雪呀！看吧，山上的矮松越发的青黑，树尖上顶着一髻儿白花，好像日本看护妇。山尖全白了，给蓝天镶上一道银边。山坡上，有的地方雪厚点儿，有的地方草色还露着；这样，一道儿白，一道儿暗黄，给山们穿上一例一件带水纹的花衣；看着看着，这件花衣好像被风儿吹动，叫你希望看见一点更美的山的肌肤。等到快日落的时候，微黄的阳光斜射在山腰上，那点薄雪好像忽然害了羞，微微露出点粉色。就是下小雪吧，济南是受不住大雪的，那些小山太秀气了。

So long as teachers fail to distinguish between teaching and learning, they will continue to undertake everything to do for children that only children can do for themselves. Teaching children to read is not passing reading on to them. It is certainly not endless hours spent in activities about reading. Douglas insists that “reading cannot be taught directly and schools should stop trying to do the impossible”.

Teaching and learning are two entirely different processes. They differ in kind and function. The function of teaching is to create the conditions and the climate that will make it possible for children to devise the most efficient system for teaching themselves to read. Teaching is also a public activity. It can be seen and observed.

Learning to read, however, involves all that each individual does to make sense of the world of printed language. Almost all of it is private, for learning is an occupation of the mind, and that process is not open to public scrutiny.

If teacher and learner roles are not interchangeable, what then can be done through teaching that will aid the child in the quest (探索) for knowledge? Smith has one principal rule for all teaching instructions. “Make learning to read easy, which means making reading a meaningful, enjoyable and frequent experience for children.”

When the roles of teacher and learner are seen for what they are, and when both teacher and learner fulfill them appropriately, then much of the pressure and feeling of failure for both is eliminated. Learning to read is made easier when teachers create an environment where children are given the opportunity to solve the problem of learning to read by reading.
