⑦在仰韶文化时期,我国就有了对竹利用的确切记载。竹自竹简、珠笔到竹纸,在保存和传播我们中华民族的古老文化上立下了汗马功劳。以竹为题材的诗词歌赋,用竹编织和雕刻的艺术品,竹制的笙管笛箫奏出的音乐,无不给人类美的享受。⑧在我国文化史上,竹蕴含着中华民族重要的精神价值。人们在长期的劳动实践和文化活动中,把竹的生物特征逐渐升华为一种做人的美德。竹四季常青,不畏逆境,和松、梅并誉为“岁寒三友”;竹中空外直,虚怀若谷,和梅、兰、菊并称为“四君子”。⑨无论是魏晋嵇康、向秀等“竹林七贤”,还是唐朝李白、韩准等“竹溪六逸”,莫不对竹有一份执着和憧憬,清代郑板桥,与竹为邻,以竹为友,爱竹、写竹、画竹、赞竹。“千磨万击还坚韧,任尔东西南北风”,正是他坚忍不拔、超凡脱俗的人格写照。
青蒿素治疗疟疾效果显著,是抵抗疟疾耐药性最好的药物。中国发现青蒿素时,美国也研制出一种抗疟新药—化学合成的甲氟喹,但疟原虫很快就适应了它,产生耐药性,临床使用后患者还出现了明显的不良反应。而对于青蒿素这种从中草药中提取的药物,疟原虫对它完全没有抵抗能力。1976 年1月,柬埔寨爆发疟疾,因疟原虫已经产生耐药性,疫情一时难以控制。中国医疗队携带一批青蒿素在柬埔寨大显神威,挽救了一大批疟疾患者的生命。

遥看起伏的山峦,心存疑惑:把店开到山顶,哪来的底气和自信?车子往山上爬的时候,是在一条不足丈宽的小路上。路已年久,不少地方坑洼不平,好几个弯道,极陡,路边不见护栏,我瞪着眼睛,双手紧紧擦着扶手。近一小时的惊恐后,终于见到被大树环绕着的一幢幢钢架结构的时尚小屋,夕阳斜照,大玻璃墙晃人眼睛,飘窗摆着素雅的靠垫。突然想起,在这高山之巅,晚饭没法下山吃了,那险窄之道,在漆黑的山林里,谁还受得了一上一下?

鱼,我所欲也;熊掌,亦我所欲也。二者不可得兼,舍鱼而取熊掌者也。生,亦我所欲也;义,亦我所欲也。二者不可得兼,舍生而取义者也。生亦我所欲,所欲有甚于生者,故不为苟得也;死亦我所恶,所恶有甚于死者,故患有所不辟也。

金风换成了北风,秋去冬来了。冬天刚刚冒了个头,落了一场初雪,我满庭斗艳争娇的芳菲,顿然失色,鲜红的老来娇,还有各色的傲霜菊花,一夜全白了头。两棵丁香,叶子簌簌辞柯了,像一声声年华消失的感叹。
