Chapter 4 'A Summary of Zhuang Zi's Poetic Thought', based on a'close reading'of thirty-three sections of Zhang Zi and the three parts'primordial thought'T's discourse'and'poetic living', systematically combs and interprets the basic framework of Zhuang Zi's poetic thought.lt starts from a'primordial thought' about a 'carefree life' that overcomes 'grief and 'heavy burdens'and obtains Toe's wisdom', and experiences a judgment of various discourses of man, a listening to the discourse of heaven and earth and a preception of 'Tao's discourse'. With this as a basis, a realm of 'poetic living' is attained: such a realm is rooted in a confirmation of 'useless use', a method of 'inaction',and an ideal state of 'floating by means of Tao-Te'.

Most of Prehistorical and historical sites in the region of the three Gorges distributed at three dale belts. At these dale belts, the banks of river were even and the thickness of soil was relative thick, which provided better inhabited location for ancient people.

三峡地区史前和历史时期考古遗址多分布在三个宽谷地带，这里江岸平缓，谷地上土层堆积相对较厚，为先民提供了适宜的居住场所，可见地貌形态是影响考古遗址分布的重要因素之一。

By the comparison between archaeological stratigraphy, sediment characteristics of cultural layers and cultural interruptions, 46 ~(14)C chronological data of buried paleotrees and peat, the synthetical analysis of the distribution laws of sites, and the reference to the results from other scholars, we can see that there are 7 cultural interruptions in the three Gorges and 7 cultural interruptions in the Yangtze Delta. They are from the last stage of Chengbeixi Culture to the initial stage of Daxi Culture (7200～6000a BP)→the third stage of Guanmiaoshan Culture Style of Daxi Culture (5800～5500a BP)→the initial stage of Shangzhou Culture (4000～3500a BP )→the last stage of Shangzhou Culture (2500～2200a BP)→During the Song dynasty Culture (960-1276AD) During the Ming and Qing Culture (1368-1911AD) in the prehistorical and historical period in the three Gorges.

对长江三峡和长江三角洲考古遗址进行地层对比，考古遗址文化层和文化断层沉积特征、文化层的叠压关系、考古遗址淤砂和淤土层厚度、46处埋藏古树和39处泥炭的~(14)C年代统计数据和空间分布规律、文化遗址分布的时空变化规律等特征综合分析，发现长江三峡地区新石器时代到历史时期考古遗址地层中有7期文化断层：(1)城背溪文化末期到大溪文化初期(7200～6000a BP)；(2)大溪文化关庙山类型三期(5800～5500a BP)；(3)商周早期(4000～3500a BP)；(4)商周晚期(2500～2200a BP)；(5)宋代时期(960-1276AD)：(6)明清时期(1368-1911AD)；(7)近现代时期。

His recently published account of his year contains a list of prematch supersitions that are so complex that he apologises to the reader in advance:the identical seat on the team coach,three sips of wateron the journey,three bananas for his pre-match meal, a seat always directly in line with the right-hand side of the screen for Mourinho's pre-match briefings.

他最近出版的年度自传中透露了他在赛前的一些迷信想法，这些迷信内容有的非常复杂，但他事先已经向读者们致歉了：他在球队大巴上总是坐相同的位置，前往球场的途中只喝3口水（从不喝4口），在赛前正餐中他必须要吃3个香蕉，在穆里尼奥赛前的吹风会上一定要坐在和屏幕右端呈直线的椅子上。

For three different reaction paths leading to ortho, meta, para-chloropyridine, two transition states have been located by PM3 on each reaction path, while only one transition state by ab initio, however both methods give the same results: the energy of transition state and activation barrier on producing 2-chloropyridine are the lowest among three reaction paths, so 2-chloropyridine is obtained priorly, which agrees with the experimental results.

生成邻、间、对氯代吡啶三条不同反应途径PM3方法优化得到两个过渡态，而从头算方法中只优化得到一个过渡态。但两种方法的研究结果均表明：三条反应途径中生成2-氯吡啶的过渡态能量和活化能最低，因此反应优先生成2-氯吡啶，与实验结果一致。

Moreover,it was demonstrated that the threesubstances,E,DE and DA,increased dramatically and quickly after LPS treatment.Also,it was revealed that the changes of three substances were more quickly than thechanges of the above mentioned APPs during the same LPS treatment.Thesesuggested that the three substances existed as neurotransmitter.The presence and thechange of the CAs in amphioxus after treated with LPS indicated the evolutionaryexistence of CAs and acute phase response in the protochordate lineage.
