乡村铁质    

刘向民   

  乡村是我永远的家园。在我全部的生活中,乡村是最重要的。

  虽然走进了城市,不可能与土地日日肌肤相亲,但我始终以农民的眼光审视乡村。乡村是城市的依托,没有乡村也就没有城市的存在,乡村是城市的母体,城市是乡村的延伸和延续。乡村是狗吠鸡鸣牛哞,是薄薄的晨雾和袅袅的炊烟,一条静静地流淌的小河,茂密的小草尖上晶莹的露珠闪耀着太阳的光彩。乡村的早晨是清新和鲜明的。

  走进田野,就走进了自我。一株株茂盛的高梁、谷子或者玉米,就是我们的兄长。闪着光芒的锄探进植物的根部,根系蔓延,锄的铁质意念就通过异常发达的根系蔓延了整个土地,广阔的原野处处闪耀着铁质的浑厚和沉重,所以我们收获的每一粒粮食、每一季粮食都包含着铁质。铁质沿着血管流动,扎根于我们的每一处神经,我们的脊梁才如此坚挺。

  粮食的存在,使乡村有了存在的充分理由。一茬一茬的庄稼,一茬一茬的人生,在乡村的远天下格外亮丽。已经死去多年的大树仍然直直地挺立,黑枯的树干直指青天,乡村中许多的构思和想象缘自树干的启迪。镰刀闪着铁质的锋利,农民的梦想始终与庄稼有关,一头牛与一架犁在土地深处探寻,浑黄或者黝黑的土壤蕴涵着无穷的力量,只要播下种子,幻想就无可阻挡地蓬勃起来了。土地时刻迸发着铁质的响声。

  土地养育了庄稼,也养育了整个乡村。乡人们的性格和作为,任何时候都充满着铁质,欢喜时会无所顾忌地畅心大笑,发怒时会打上一架,或者跑到村街上不明不白地骂上一场,悲哀时会痛痛快快淋漓尽致地大哭一场,然后又执著地走进田野,走进劳作,一切都毫无遮遮掩掩。嫉恶如仇,旗帜鲜明,高昂的气概和高亢的声音比得过任何烦琐深奥的说教。他们不怕风,不怕雨,不怕雷鸣,他们饮风露餐,吃得下千般苦,受得住万般罪,他们常说“没有吃不了的苦,没有受不了的罪”,年景的丰歉和日子的辛苦都是岁月的点缀,他们从不怨天尤人,总烫日出而作,日落而息,沿着太阳的方向走进田野,走进庄稼地里,走进乡村深处的每一个细节,使乡村的每一刻都充充实实和铿锵,有声。哪怕只是一声劳动的号子,也如雷鸣一般响亮;哪怕只是向前迈出一步,也如山一般稳重;哪怕只是一个耕或者种的手势,也都是乡村的经典动作。乡村,处处铁质,铁质处处。

  乡村是农民的部落。城里人已经厌烦的事情,乡村还在喜欢或者也早已厌烦,喜欢的是一种没有丢失的乡村质朴,厌烦的是曾经生活在乡村里的城里人的造作。城里人始终也在吃着乡村的粮食,但缺少了乡村的铁质。铁质似乎已被城里人丢失殆尽。我们是否要寻找乡村的铁质,使乡村铁质在城市里闪烁,应该是我们思考的问题。

  乡村是我们生存的依托,也是城市生活的依据,没有了乡村就没有城市。是否有人为城市的一天天的侵占乡村沾沾自喜呢?如果缺少了乡村,缺少了乡村铁质,我们将会更加颓废,城市也将因此而变得莫名其妙地失去方向。因此,不论生活在乡村还是城市里的人们,都不能忘记永远的乡村铁质,它是我们永远的支撑,我们永远的方向。  (选自《散文选刊》2006年1期)

    An allergy (过敏反应) is a strong reaction to a substance. Many things can cause

allergies. The most common cause is pollen (花粉), which is usually produced by trees in

the spring, grasses in the summer and weeds in the fall, as part of their reproductive

process.

    Other causes include organisms, chemicals, plants and dead skin particles (微粒) from

dogs and cats can also cause allergic reactions. So can insect stings and some food.

    The most common kind of allergic reactions is itchy (痒的), watery eyes and a blocked

or watery nose. Allergies can also cause red, itchy skin. Some reactions can be life-

threatening, for example, when breathing passages become blocked.

    It is not always easy to avoid allergies. Drugs may offer an effective treatment.

injected with small amounts of the allergy-causing substance. The idea is that larger and

larger amounts are given over time until the patient develops a resistance in his body.

allergies. Every year these allergies cause about 30,000 cases with severe reactions that

by peanuts and tree nuts like walnuts.

Immunology says about 10% of bad reactions to commonly used medicines are allergic. In
