阅读短文，下列问题

A

       There was once a tree. It was the biggest tree in the forest. However, the tree would never share its shadow (阴影) with any of the animals and wouldn't let them come anywhere near.

       One year, the winter was terrible (令人不快的). And the tree, without its leaves, was going to die of cold. A little girl found the poor tree when she went to live with her grandma that winter. So she went to get a great scarf to warm the tree up. At that time, the Spirit (仙子) of the Forest appeared. She told the little girl why that tree was so lonely and why no one would help it. Even so, the girl decided to put the scarf on the tree.

       The next spring, the tree learnt from the girl's kindness. When she sat next to it, the tree put itself down to give her shadow and let her keep away from the sun. The Spirit of the Forest saw this and went to tell all the animals. She told them that from then on they could get shadow from the tree, because it learnt a lesson. If there are more kind and generous humans around, the world will be a much better place to live in.     

阅读《济南的冬天》节选，完成下列小题。

      ①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，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!

      ②古老的济南，城里那么狭窄，城外又那么宽敞，山坡上卧着些小村庄，小村庄的房顶上卧着点雪，对，这是张小水墨画，也许是唐代的名手画的吧。
