阅读夏阳的《苦雪烹茶》,完成后面小题。

    ①山里有一庙,庙里有一老和尚。老和尚不喜念经拜佛,每天吃饱喝足,躺在庙门口的草地上晒太阳,观山间云生雾起。

    ②岁末,天寒地冻,天阴阴沉沉的,像要下雪了,老和尚正坐在寺庙内烤火。这时,推门进来一个不速之客,是个年轻人,背着大包小包,逃难一样。

    ③你想出家?老和尚烤着火,平静地问年轻人。这会儿,窗外的雪纷纷扬扬地下了起来。年轻人也围坐在火炉旁,搓着两只冻得通红的手,认真地点了点头。

    ④何故?

    ⑤年轻人脸上抽搐着,痛苦地说,我觉得活着没啥意思,我女朋友跟了别人,她嫌我家里穷,嫌我父母下岗。可是,我真的很爱她!

    ⑥还有吗?

    ⑦有,多呢!我写的文章倍儿棒,可是编辑就是不搭理我。这年头,你想发表作品,得帮他们拉广告。我单位的领导,经常给我穿小鞋,事事刁难我。我父母……

    ⑧老和尚摆手打断年轻人的话,认真查看年轻人的行李,问,你带篮球来做什么?年轻人以为老和尚喜欢篮球,眼里亮了—下,说,我怕山上没啥事儿干,我们可以一起玩玩篮球打发时间。老和尚苦笑着,去厨房寻了把菜刀,递给年轻人,严肃地说,本庙有一规矩,只收哑巴,你想入佛门,得割掉舌头,了断人间是非!

    ⑨割舌头?什么破规矩,太恐怖了!太残忍了!会流很多血的,会很痛的,说不定还会死的!年轻人握着菜刀,倚到墙上,感觉舌头上凉飕飕的,如同有锋利的刀刃在慢慢滑过。年轻人呆若木鸡。老和尚摇了摇头,轻轻卸下年轻人手里的菜刀,口中说道,阿弥陀佛,像你这样尘缘未了的迷路者,我已经接待过16位,施主你是第17位。年轻人满脸羞愧,搓着两只手,不敢吱声。

    ⑩老和尚望了望窗外。这时,漫天大雪,鹅毛般在飘。老和尚一施礼,说,小施主,你稍坐片刻,我去去就来。回来时,他一身洁白,右手提着半桶白如梅的雪,左手折了几枝白如雪的梅。老和尚掸去身上的雪,端出一个瓦罐坐在火炉上,从桶里挖了些雪倒进去。瓦罐无盖,残了一只耳朵。雪,在瓦罐里渐渐融化,化成泉水的幽冽,缓缓呜咽开来,热气升腾,舞姿婀娜。老和尚盛了一碗烧开的雪水递过去。年轻人接过碗,嘴伸了过去──烫!老和尚一笑,少安毋躁,小施主你性子太急,不可取。

    ⑪稍凉,年轻人再喝。老和尚问,何味?

    ⑫无味。再品。

    ⑬年轻人嘴里咂巴了一会儿,说,有点苦,一点点。

    ⑭善哉!因苦而苦,发乎于情,出世入世,常修菩提心。老和尚继续说,煮茶,上等水为山泉水,其次是江河水,再次是井水,最次是雪融水。雪融水乃天赐之水,淡而无味,兼苦,如尘世如俗人……老和尚的话,让年轻人的心绪渐渐宁静。老和尚又在瓦罐里添了些茶叶。沸腾间,茶叶在水里恣意行走,舒展开自己慵懒的身体,禅境悠远。

    ⑮老和尚递过一碗茶,年轻人抿了一口。如何?无味?

    ⑯清甜,怡人可口!年轻人孩子似的笑了。

    ⑰香吗?年轻人思考了一下,肯定地说,不香!

    ⑱老和尚折下几朵梅花,搁入瓦罐,用木勺小心地搅动了几下,又盛了一碗给年轻人。梅花在碗里怒放,一股淡雅的清香氤氲开来,花房般温暖。年轻人笑着说,不用品了,没喝就香满屋了。

    ⑲其实最好的茶水非山泉水,而是寒梅之苦雪。为何?你是读书之人,应该明白这里面的道理。

    ⑳年轻人遥看窗外。雪停了,白茫茫一片,如童话世界。三天后,年轻人下山了。

同类题3

选择适当的选项填到对应的空

     Teaching your child to read can be one of the most rewarding(值得的) experiences you have as a parent.

____

      Nothing can replace the head start(起步时的优势)that a child receives from becoming familiar with books and the way that the written word sounds when read aloud. If your child sees that reading is important to you, then he will be much more likely to want to learn how to read himself.

____

       If your child shows interest in learning letters and looking through books, he may be ready to begin learning to read. Learning how to read cannot be rushed. If your child has no interest in learning his letters, then wait a month or so and try again.

____

      You can make this fun, such as saying “I see a k-æ-t-cat” whenever you see a cat. The sound of a letter is much more important than a letter's name because the child will need to combine the letter sounds to make words.

____

      Some children learn their letters faster by seeing or hearing them, while other children learn letters by using their bodies. Encourage your child to draw the letter and then paste pictures of something that begins with that sound onto the letter. Sing songs about the letter. Read your child a story that repeatedly uses that letter sound.

____

      Rather than try to teach a child 26 new letters at one time, focus on one letter a day or a week. This enable the child to master each letter sound and feel proud of himself/herself for doing so.


A. Read to your child daily.

B. Show your child your love for reading.

C.  Make sure your child is ready to begin learning how to read.

D. Focus on one letter at a time.

E. Teach your child the sound of each letter.

F. Use sight, sound and touch as you teach each letter.
