⑦在仰韶文化時期,我國就有了對竹利用的確切記載。竹自竹簡、珠筆到竹紙,在保存和傳播我們中華民族的古老文化上立下了汗馬功勞。以竹為題材的詩詞歌賦,用竹編織和雕刻的藝術(shù)品,竹制的笙管笛簫奏出的音樂,無不給人類美的享受。⑧在我國文化史上,竹蘊含著中華民族重要的精神價值。人們在長期的勞動實踐和文化活動中,把竹的生物特征逐漸升華為一種做人的美德。竹四季常青,不畏逆境,和松、梅并譽為“歲寒三友”;竹中空外直,虛懷若谷,和梅、蘭、菊并稱為“四君子”。⑨無論是魏晉嵇康、向秀等“竹林七賢”,還是唐朝李白、韓準等“竹溪六逸”,莫不對竹有一份執(zhí)著和憧憬,清代鄭板橋,與竹為鄰,以竹為友,愛竹、寫竹、畫竹、贊竹。“千磨萬擊還堅韌,任爾東西南北風”,正是他堅忍不拔、超凡脫俗的人格寫照。
青蒿素治療瘧疾效果顯著,是抵抗瘧疾耐藥性最好的藥物。中國發(fā)現(xiàn)青蒿素時,美國也研制出一種抗瘧新藥—化學合成的甲氟喹,但瘧原蟲很快就適應了它,產(chǎn)生耐藥性,臨床使用后患者還出現(xiàn)了明顯的不良反應。而對于青蒿素這種從中草藥中提取的藥物,瘧原蟲對它完全沒有抵抗能力。1976 年1月,柬埔寨爆發(fā)瘧疾,因瘧原蟲已經(jīng)產(chǎn)生耐藥性,疫情一時難以控制。中國醫(yī)療隊攜帶一批青蒿素在柬埔寨大顯神威,挽救了一大批瘧疾患者的生命。

遙看起伏的山巒,心存疑惑:把店開到山頂,哪來的底氣和自信?車子往山上爬的時候,是在一條不足丈寬的小路上。路已年久,不少地方坑洼不平,好幾個彎道,極陡,路邊不見護欄,我瞪著眼睛,雙手緊緊擦著扶手。近一小時的驚恐后,終于見到被大樹環(huán)繞著的一幢幢鋼架結(jié)構(gòu)的時尚小屋,夕陽斜照,大玻璃墻晃人眼睛,飄窗擺著素雅的靠墊。突然想起,在這高山之巔,晚飯沒法下山吃了,那險窄之道,在漆黑的山林里,誰還受得了一上一下?
于是,每到冬日,我會有意無意念起熨帖在冬日木格窗欞上的冰窗花。冬日的居室里,總會生了爐火,白日里,落了雪,一家人和和暖暖地或斜倚、或平躺在溫熱的土炕上。
魚,我所欲也;熊掌,亦我所欲也。二者不可得兼,舍魚而取熊掌者也。生,亦我所欲也;義,亦我所欲也。二者不可得兼,舍生而取義者也。生亦我所欲,所欲有甚于生者,故不為茍得也;死亦我所惡,所惡有甚于死者,故患有所不辟也。

金風換成了北風,秋去冬來了。冬天剛剛冒了個頭,落了一場初雪,我滿庭斗艷爭嬌的芳菲,頓然失色,鮮紅的老來嬌,還有各色的傲霜菊花,一夜全白了頭。兩棵丁香,葉子簌簌辭柯了,像一聲聲年華消失的感嘆。
