       佛祖道:“我与你打个赌赛:你若有本事,一筋斗打出我这右手掌中,算你赢,再不用动刀兵苦争战,就请玉帝到西方居住,把天宫让你;若不能打出手掌,你还下界为妖,再修几劫,却来争吵。”大圣闻言,暗笑道:“这如来十分好呆!我老孙一筋斗去十万八千里。他那手掌,方圆不满一尺,如何跳不出去?”急发声道:“既如此说,你可做得主张?”佛祖道:“做得,做得!”伸开右手,却似个荷叶大小。那大圣收了如意棒,抖擞神威,将身一纵,站在佛祖手心里,却道声:“我出去也!”你看他一路云光,无影无形去了。佛祖慧眼观看,见那猴王风车子一般相似不住,只管前进。大圣行时,忽见有五根肉红柱子,撑着一股青气。他道:“此间乃尽头路了。这番回去,如来作证,灵霄宫定是我坐也。”又思量说:“且住!等我留下些记号,方好与如来说话。”拔下一根毫毛,吹口仙气,叫:“变!”变作一管浓墨双毫笔,在那中间柱子上写一行大字云:“齐天大圣到此一游。”写毕,收了毫毛。又不庄尊,却在第一根柱子根下撒了一泡猴尿。翻转筋斗云,径回本处,站在如来掌内道:“我已去,今来了。你教玉帝让天宫与我。”如来骂道:“我把你这个尿精猴子!你正好不曾离了我掌哩!”大圣道:“你是不知。我去到天尽头,见五根肉红柱,撑着一股青气,我留个记在那里,你敢和我同去看么!”如来道:“不消去,你只自低头看看。”那大圣睁圆火眼金睛,低头看时,原来佛祖右手中指写着“齐天大圣到此一游”。大指丫里,还有些猴尿臊气,大圣吃了一惊道:“有这等事,有这等事!我将此字写在撑天柱子上,如何却在他手指上?莫非有个未卜先知的法术。我决不信,不信!等我再去来!”好大圣,急纵身又要跳出,被佛祖翻掌一扑,把这猴王推出西天门外,将五指化作金木水火土五座联山,唤名“五行山”,轻轻的把他压住。

根据短文内容出选择正确答案。

     A farmer had a brother in town who was a gardener, and his brother had a garden full of the finest fruit trees. So his skill and his beautiful trees were famous everywhere. One day the farmer went into the town to visit his brother, and was surprised at the trees that grew quite well.

      "Look, my brother," said the gardener. "I will give you an apple tree, the best from my garden, and you, and your children, and your children's children will enjoy it."

       Then the gardener called his workmen and ordered them to take up the tree and carry it to his brother's farm. They did so, and the next morning the farmer began to wonder where he should plant it.

"If I plant it on the hill," he said to himself, "the wind might catch it and shake down the delicious fruit before it is ripe. If I plant it close to the road, passersby will see it and take away the apples--but if I plant it too near the door of my house, my children may pick the fruit." So, after he had thought the matter over, he planted the tree behind his barn (谷仓).

      Time passed, but the tree had no fruit the first year, nor the second-then the farmer called his brother. When the gardener came, the farmer said angrily, "You have cheated me, and given me a useless tree instead of a fruitful one. This is the third year and still it brings out nothing but leaves! "

      The gardener laughed and said, "See where the tree was planted, it has no sun or warmth. How could you expect flowers and fruit?"
