生命(ming)的壮歌———“生命(ming)桥(qiao)”
沈石溪
随(sui)(sui)着(zhe)(zhe)镰刀头羊的(de)(de)(de)那(nei)声(sheng)吼叫，整个(ge)斑(ban)(ban)羚(ling)(ling)(ling)(ling)(ling)(ling)群迅速分(fen)成两拨(bo)(bo)(bo)，老年(nian)(nian)斑(ban)(ban)羚(ling)(ling)(ling)(ling)(ling)(ling)为(wei)一(yi)拨(bo)(bo)(bo)，年(nian)(nian)轻(qing)(qing)斑(ban)(ban)羚(ling)(ling)(ling)(ling)(ling)(ling)为(wei)一(yi)拨(bo)(bo)(bo)。在老年(nian)(nian)斑(ban)(ban)羚(ling)(ling)(ling)(ling)(ling)(ling)队伍里(li)，有公(gong)斑(ban)(ban)羚(ling)(ling)(ling)(ling)(ling)(ling)，也(ye)(ye)有母斑(ban)(ban)羚(ling)(ling)(ling)(ling)(ling)(ling)；在年(nian)(nian)轻(qing)(qing)斑(ban)(ban)羚(ling)(ling)(ling)(ling)(ling)(ling)队伍里(li)，年(nian)(nian)龄参差(cha)不(bu)齐，有身(shen)强(qiang)力壮的(de)(de)(de)中年(nian)(nian)斑(ban)(ban)羚(ling)(ling)(ling)(ling)(ling)(ling)，有刚刚踏进(jin)成年(nian)(nian)行列的(de)(de)(de)大斑(ban)(ban)羚(ling)(ling)(ling)(ling)(ling)(ling)，也(ye)(ye)有稚气未脱的(de)(de)(de)小斑(ban)(ban)羚(ling)(ling)(ling)(ling)(ling)(ling)。两拨(bo)(bo)(bo)分(fen)开后(hou)，老年(nian)(nian)斑(ban)(ban)羚(ling)(ling)(ling)(ling)(ling)(ling)的(de)(de)(de)数量比年(nian)(nian)轻(qing)(qing)斑(ban)(ban)羚(ling)(ling)(ling)(ling)(ling)(ling)那(nei)拨(bo)(bo)(bo)少十(shi)来只。镰刀头羊本来站在年(nian)(nian)轻(qing)(qing)斑(ban)(ban)羚(ling)(ling)(ling)(ling)(ling)(ling)那(nei)拨(bo)(bo)(bo)里(li)，眼光在两拨(bo)(bo)(bo)斑(ban)(ban)羚(ling)(ling)(ling)(ling)(ling)(ling)间转了(le)几(ji)个(ge)来回(hui)，悲怆地轻(qing)(qing)咩了(le)一(yi)声(sheng)，迈着(zhe)(zhe)沉重的(de)(de)(de)步伐走(zou)到老年(nian)(nian)斑(ban)(ban)羚(ling)(ling)(ling)(ling)(ling)(ling)那(nei)一(yi)拨(bo)(bo)(bo)去了(le)。有几(ji)只中年(nian)(nian)公(gong)斑(ban)(ban)羚(ling)(ling)(ling)(ling)(ling)(ling)跟随(sui)(sui)着(zhe)(zhe)镰刀头羊，也(ye)(ye)自动从年(nian)(nian)轻(qing)(qing)斑(ban)(ban)羚(ling)(ling)(ling)(ling)(ling)(ling)那(nei)拨(bo)(bo)(bo)里(li)走(zou)出(chu)来，归进(jin)老年(nian)(nian)斑(ban)(ban)羚(ling)(ling)(ling)(ling)(ling)(ling)的(de)(de)(de)队伍。这么一(yi)来，两拨(bo)(bo)(bo)斑(ban)(ban)羚(ling)(ling)(ling)(ling)(ling)(ling)的(de)(de)(de)数量大致均衡(heng)了(le)。

试跳(tiao)成功。紧接着，一(yi)对对斑羚凌空(kong)跃起，在山涧(jian)上空(kong)画出一(yi)道道令(ling)人(ren)
yǎn huā liáo luàn( )的弧线，每一(yi)(yi)只年轻斑(ban)羚(ling)的成功飞(fei)渡，都(dou)意(yi)味着(zhe)有(you)(you)一(yi)(yi)只老(lao)年斑(ban)羚(ling)摔(shuai)得粉(fen)身碎(sui)骨。山(shan)涧上(shang)空，和(he)那道(dao)(dao)彩虹平行，又架起(qi)了(le)一(yi)(yi)座桥，那是一(yi)(yi)座用死(si)亡(wang)做桥墩架设起(qi)来的桥。没有(you)(you)拥挤，没有(you)(you)争夺，zhì xù jǐng rán( )，快(kuai)速飞(fei)渡。我十分注(zhu)意(yi)盯着(zhe)那群(qun)注(zhu)定要送死(si)的老(lao)斑(ban)羚(ling)，心想，或(huo)许(xu)有(you)(you)个(ge)别(bie)滑头的老(lao)斑(ban)羚(ling)会(hui)从注(zhu)定死(si)亡(wang)的那拨(bo)(bo)偷偷溜到(dao)新生的那拨(bo)(bo)去，但(dan)让我震惊的是，从头至尾(wei)没有(you)(you)一(yi)(yi)只老(lao)斑(ban)羚(ling)调换(huan)位置(zhi)。它们心甘情(qing)愿用生命为下一(yi)(yi)代开辟一(yi)(yi)条生存了(le)道(dao)(dao)路。
绝大部分(fen)老斑(ban)羚(ling)都用高超的(de)(de)跳跃技艺，帮助(zhu)年轻斑(ban)羚(ling)平安地飞渡到(dao)对岸的(de)(de)山峰，只有一(yi)(yi)头(tou)衰(shuai)老的(de)(de)母斑(ban)羚(ling)，在(zai)和(he)一(yi)(yi)只小(xiao)斑(ban)羚(ling)空中衔接时，大概(gai)力不从(cong)心，没(mei)能(neng)让(rang)小(xiao)斑(ban)羚(ling)踩上自己的(de)(de)背，一(yi)(yi)老一(yi)(yi)小(xiao)一(yi)(yi)起(qi)坠进深渊(yuan)。
我没(mei)(mei)想到，在面临种(zhong)群灭(mie)绝的(de)关键时刻，斑羚群竟然想出牺牲一半挽(wan)救(jiu)另(ling)一半的(de)办法(fa)来赢得种(zhong)群的(de)生存机会。我更没(mei)(mei)想到，老斑羚们会那么从(cong)容地走向死亡(wang)。
我看得(de)目瞪(deng)(deng)口呆(dai)，所有的猎人都看得(de)目瞪(deng)(deng)口呆(dai)，连狗也惊讶地张大嘴，伸(shen)出了长长的舌头。
