爱藕说

       映日荷花,接天连叶,亭亭莲蓬和藕,本是四位一体的。

       爱佼佼荷花者有之,咏田田莲叶者有之,赞点点莲子者有之。偏心的诗人哟,为何厚此薄彼?为什么不肯为嫩藕多唱几支短歌?

       藕,自生与世间,变委身水下,不见日月,在浊泥污土的围困中生活。一旦出淤泥。风采翩翩,洁似玉,白如学,一尘不染。不是贞洁操守。孰能如此?它孔窍玲珑,称得起虚心;它居下而有节,贫贱不屈;它虽然嫩而且柔,藕牙儿却能穿透青泥碧水,劲挺起翡翠一般的绿茎,托起红花碧叶,算得上是柔中有刚。古人将六月二十四日,奉为荷花节日。默默困顿于泥水里的藕,谁知它声于何时?它像竹鞭那样,孕出藕牙,长大开花,再生出莲子以续生生之脉,谁知它年寿几何?它节节横生,从未与花叶争宠夺艳,甘居地下,无日无夜的托着花儿叶儿,像是母亲的玉臂偎抱着幼子,睡知它有几多辛劳?

       给我一支花的诗笔吧,我想寻找动情的诗句,写给养育那莲花的母亲——玉藕;

       也想把真挚的感情奉献给千千万万的妇女——伟大的含辛茹苦的母亲!

咏莲

       迸发出心中最真的火焰,打印在夏日的扉页中的是莲。你在这里重新锤炼,终于挣脱出那泥牢中的锁链,婷婷盛开在这苍茫大地间,向世人倾诉着至善的语言。坚忍的意志在这苦海中尽显,最终铸成一朵金刚净莲。

       心中的一团圣火,理想中的一只白鸽,都成了你的主宰,多少智者依你而眠,多少善者永远在心中把你挂牵。看那一柄净碧的荷叶荡涤着人们迷中的眼,一片淡粉的莲瓣成了多少代人的梦幻,凸起的莲籽成了永不改变的琴键,奏响了激荡万古的乐章。人间的一朵净花,凡尘的一方净土。生命因你而明白了纯净的内涵——哦,莲!

莲子

       中国是莲子的故乡。早在五千年前仰韶文化遗址中,就曾发掘到两粒莲子;三千年前的《诗经》中,就有“隰有荷花”的诗名。

       莲子补中养神,止渴去热,厚肠胃,固精气,强筋骨,补虚损,利耳目,除寒湿,是一种纯天然高级营养保健品,历来为御膳房必备之物。莲子食用方便,既可制成莲子羹,莲子汤,八宝粥,糖水莲子,又可炖鸡,炖鸭等制作美味佳肴,是强身健体,养颜驻容,馈赠亲友的上等佳品。

       产于浙江宣平的莲子更有它的独到之处。一般的莲子颗粒较小,久煮不酥,而宣莲由于本地独特的土质和气候条件,颗粒较大(465粒即达500克),酥而不烂,味美爽口。它含有高蛋白质、钙、磷、镁等多种物质。因而浙江宣莲成了历代的贡品。

    Can people change their skin color without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin color.

    The gene comes in two versions, one of which is found in 99 percent of Europeans. The other is found in 93 to 100 percent of Africans, researchers at Pennsylvania State University report in the latest issue of Science.

    Scientists have changed the color of a dark-striped zebra-fish(斑马鱼) to uniform gold by inserting a version of the pigment (色素) gene into a young fish. As with humans, zebra-fish skin color is determined by pigment cells, which contain melanin (黑色素). The number, size and darkness of melanin per pigment cell determine skin color.

    It appears that, like the golden zebra-fish, light-skinned Europeans also have a mutation (变异) in the gene for melanin production. This results in less pigmented skin.

    However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebra-fish genes.

    Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun (太阳光紫外线), which can cause skin cancer.

    But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng.

    Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin color, said Cheng.

    The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin color without damaging it like chemical treatment did on Michael Jackson.
