阅读《雪夜》,回答下列小题。

雪夜

张爱国

    ①那是一个飘雪的冬夜。天地间一片死寂,只有大朵大朵的雪花落地的“沙沙”声。虽然裹着厚厚的棉袍棉裤,但还是无法抵御彻骨的寒气。我弓腰缩背,双手紧拢,踩着没过脚踝的雪,跟着父亲走向村外的后岗。父亲仿佛看出了我的怨气,说:“今晚一定能捉住那个贼。”

    ②“不就几捆稻草吗?大半夜还出来受冻!”我没好气地说,我总以为父亲是小题大做。

    ③“你说的轻巧,没了稻草,开春后咱家大牯牛吃什么?”父亲说着就愤愤起来,“再说了,不要脸的贼你不捉住他,还不知要祸害多少人呢!”

    ④到了后岗,父亲用手电筒四下照了照,茫茫雪地里,只有我家一大一小两个草堆,顶着厚厚的雪,静静地矗立着。我和父亲钻进小草堆洞里,茫然地看着黑咕隆咚的雪的世界。

    ⑤草堆洞里虽然比外面暖和了许多,但绝比不上家里,更比不了暖和的被窝,我的双脚很快就冻得生疼。“今晚不会有贼了吧?”我说——我想让父亲同意我们早点撤退,可父亲却传出了轻微的鼾声——他天天劳作不闲,今儿又推了一整天的磨,实在太困了。

    ⑥不知过了多久,雪停了,却下起了冰子,纷纷扬扬地撒进草堆洞。草堆洞俨然成了冰窖,没有一丝温度。我正要推醒父亲回家,却见一窝微弱的灯光向这边慢慢移来。很快,我看到了,是两个孩子,一大一小,提着防风的煤油灯,径直来到我家大草堆前。

    ⑦“从里面拉,轻点,别拉倒了草堆。”小个子低声对大个子说,还挥了挥右臂——半截的右臂!天啊,她不是孩子,是矮婶啊!我忘记了推醒父亲,矮婶怎么会干这种事?怎么干这种事还带着儿子小江——小江比我还小一岁啊。

    ⑧小江双手抓着一捆稻草使劲往外拉,一个没注意,重重地滑倒在雪地里。矮婶急忙上前扶起,叫他接着拉。小江嘴里却愤愤地嘀咕着什么,站立一旁,不愿拉了。寒风中,母子俩僵持着,浑身颤抖——小江上身穿一件破棉袄,下身是一件旧单衣,而矮婶上下身穿的都是破旧的单衣。

    ⑨矮婶放下煤油灯,用左手吃力地拉着小江刚刚拉过的那捆稻草,可稻草压得太紧,她发了好几次力也拉不下。小江终于不忍,上去帮忙,母子俩好不容易才拉下了一捆稻草。然后,他们又合力拉下一捆。矮婶提起一捆稻草就要回家,小江却犹豫着说:“娘,再拉一捆吧,够牛吃三天了。”矮婶看看草堆,摇着头说:“算了吧,你四伯家的牛也要吃草呢。”说完,母子俩就提着稻草一前一后地往回走。

    ⑩我已经决定不叫醒父亲让他们走了,可父亲却突然醒来,一声大叫,明亮的手电筒的光就照上了三四丈开外的母子俩身上。我急忙抓住要往外冲的父亲,与此同时,父亲刚出口的“不要脸的……”也硬生生地吞回了半句——他也似乎明白了什么,慢慢地坐回原地。

    ⑾手电筒的灯光里,矮婶怀抱稻草,弯着腰,脸紧紧地贴着稻草,一动不动。

    ⑿呼呼的北风掀翻她单薄的衣服,枯瘦的后背整个地裸露在寒风中,任由密密的冰子肆无忌惮地击打。小江更是吓坏了,提着稻草,浑身颤抖得异常厉害。

    ⒀“是矮婶。”我贴着父亲的耳朵低低地说。

    ⒁“哦,拿草的是二柱三柱吧……你们……”父亲关了手电筒,大声地说,“你们拿回去吧,明天……明天我再找你们算账……”

    ⒂回到家,母亲还坐在床上纳鞋底,问我们抓没抓到贼。见我们谁也不说话,母亲才发现我们的神情很凝重,就一再追问到底发生了什么。

    ⒃“哎,老天造孽啊!”父亲长长地叹口气说,“你这就起来,给桂香送稻草去……”

    ⒄“是桂香啊?”母亲吃惊地大张着嘴,继而猛拍脑门,懊恼地说,“我应该早就想到是她娘几个了——秋天草堆失了火。”母亲一边穿着衣服,一边喃喃地说,“一个女人家,一见人就脸红,手又不便,还带着那么多孩子,再加上牲口,这冰天雪地的草不够用,可怎么熬啊……”

    ⒅此后,每隔两三天,夜深人静的时候,母亲就带着我,将几捆稻草悄悄地放到矮婶家的门口。

    ⒆又是一个大雪夜,送草回来,我很快地进入了梦乡,梦中依稀看见矮婶家的四周长出了青草,一片连着一片,郁郁葱葱,蓬蓬勃勃……

阅读理解

    Why do you go to the library? For books, yes--but you like books because they tell stories. You hope to get lost in a story or be transported into someone else's life. At one type of library, you can do just that--even though there's not a single book.

    At a Human Library, instead of books, you can “borrow” people. Individuals volunteer as human “books” and participants in the event can “read” the book--meaning they would have a one-on-one conversation with the volunteer and share in a dialogue about that individual's experience. “Books” are volunteers from all walks of life who have experienced discrimination (歧视) based on race, religion, class, gender identity, age, lifestyle choices, disability and other aspects of their life

    For a certain amount of time, you can ask them questions and listen to their stories, which are as fascinating and as attractive as any you can find in a book. Many of the stories have to do with some kind of stereotype. You can speak with a refugee (难民), a soldier suffering from PTSD, a homeless person or a woman living with HIV. The Human Library encourages people to challenge their own long-held beliefs-to truly get to know, and learn from someone they might otherwise make a quick judgment about.

    According to its website, the Human Library is “a place where difficult questions are expected, appreciated and answered.” It provides the opportunity for the community to share and understand the experiences of others in their community.

    The Human Library Organization came to be in Copenhagen, Denmark in 2000. Ronni Abergel, his brother Dany, and some colleagues hosted a four-day event during a major Northern European festival, hoping to raise awareness about violence among youth. After the success of this event, Abergel founded the Human Library Organization, which has been growing ever since.

    Though there are a few permanent human libraries, most aren't places at all, but events. Though many do take place at physical libraries, you don't need a library card—anyone can come and be part of the experience. There have been human library events all over the globe, in universities and in pubs, from Chicago to Tunis to Edinburgh to San Antonio.

    The stories these "books" tell range from fascinating to heartbreaking and everything in between. And that's the very point of the organization--to prove that no person can be summed up in just one word. It seeks to show people that you truly can't judge a book by its cover---or by its title or label.
