眼睛看到的是阳光,耳朵听到的是鸟语,鼻子嗅到的是花香,口中许下的是诺言,双手握住的是机遇,肩膀上扛起的是责任。当盘古用肩膀打起蓝天时,他肩负的责任是为大地上、蓝天下所有生灵创造生存空间。于是他的血液流淌成江河,身躯矗立成高山,呼吸幻化为微风,泪水挥洒作细雨,当他用双肩挑起日月,他用生命成就肩负的责任。当女娲用肩膀担起五色石时,她肩负起了为暴雨中的生命创造一方晴空的责任。于是,她燃起熊熊烈火,任滚滚浓烟黯淡她明亮的双眸,任红热炭火灼伤她的细嫩肌肤。当她用柔弱肩膀担起五色石飞向倾斜的天柱,她用美丽成就肩负的责任。当大禹一次次用肩膀担起泥沙时,他肩负的责任不是自己一个小家的安 相似文献

Objective: We aim to describe the environment iodine concentration in salt, water and soil along Zhejiang Province coast in the China foreland. It will be helpful for us to judge whether this area is insufficient in iodine and universal iodized salt is necessary or not. Methods: We collected iodized salt samples, drinking water samples (tap water in the towns, and well water or spring water in the villages), water samples from different sources (ditches, lakes, rivers) and soil samples through random sampling in June, 2005. Salt, water and soil iodine was detected by arsenic-cerium redox method. Statistical analysis was expressed as mean±SEMby Windows SPSS 13.0. Results: (1) The iodine concentration in salt was 27.9±4.33 mg/kg (n=108). (2) Seventy-five water samples were collected. The water iodine value was 0.6~84.8 μg/L (mean of 11.66 μg/L). The watershed along the Qiantang River has significantly higher iodine content than the water in Lin'an in mountain area (P<0.01). The iodine content and mean iodine content of tap water, well or spring water and natural water sources were 4.30±2.43 μg/L (n=34), 23.59±27.74 μg/L (n=19)and 12.72±10.72 μg/L (n=22) respectively. This indicated that among environmental water sources, the ditch iodine content was the highest with river water iodine being the lowest (P<0.01). (3) Soil iodine value was 0.11~2.93 mg/kg (mean of 1.32 mg/kg).Though there was no statistical difference of soil iodine in different districts (P=0.131), soil iodine content correlated positively with water iodine content. Conclusion: Iodine concentration in salt accords with national policy of adding iodine in salt. Foreland has more iodine in water than mountain area. The data reflected that water and soil iodine in foreland area was not high, which suggests universal iodized salt should be necessary. Environment iodine has relatively close association with pollution. 相似文献

有个渔人有着一流的捕鱼技术,被人们尊称为“渔王”。然而“渔王”年老的时候非常苦恼,因为他的三个儿子的渔技都很平庸。
于是他经常向人诉说心中的苦恼:“我真不明白,我捕鱼的技术这么好,我的儿子们为什么这么差?我从他们懂事起就传授捕鱼技术给他们,从最基本的东西教起,告诉他们怎样织网最容易捕捉到鱼,怎样划船最不会惊动鱼,怎样下网最容易请鱼入瓮。他们长大了,我又教他们怎样识潮汐,辨鱼汛……凡是我长年辛辛苦苦总结出来的经验,我都毫无保留地传授给了他们,可他们的捕鱼技术竟然赶不上技术比我差的渔民的儿子!” 相似文献
